  1. Biological Markers for Alcohol Withdrawal Seizures: A Retrospective Analysis


    Karagülle, Deniz; Heberlein, Annemarie; Wilhelm, Julia; Frieling, Helge; Kornhuber, Johannes; Bleich, Stefan; Hillemacher, Thomas


    Aims: Alcohol withdrawal seizures (AWS) are among the most important possible complications during the detoxification treatment of alcohol-dependent patients. Pharmacological therapy is often used during detoxification, but can cause dangerous side effects [Eur Addict Res 2010;16:179– 184]. In separate studies several biological markers have been described as being associated with AWS risk. We investigated the role of homocysteine (HCT), carbohydrate-deficient transferrin (CDT) and prolactin ...

  3. The alcohol withdrawal syndrome.

    LENUS (Irish Health Repository)

    McKeon, A


    The alcohol withdrawal syndrome (AWS) is a common management problem in hospital practice for neurologists, psychiatrists and general physicians alike. Although some patients have mild symptoms and may even be managed in the outpatient setting, others have more severe symptoms or a history of adverse outcomes that requires close inpatient supervision and benzodiazepine therapy. Many patients with AWS have multiple management issues (withdrawal symptoms, delirium tremens, the Wernicke-Korsakoff syndrome, seizures, depression, polysubstance abuse, electrolyte disturbances and liver disease), which requires a coordinated, multidisciplinary approach. Although AWS may be complex, careful evaluation and available treatments should ensure safe detoxification for most patients.

    Full Text Available Objective: To evaluate the effect of Ashwagandha (ASW in attenuation of alcohol withdrawal in ethanol withdrawal mice model. Methods: Alcohol dependence was induced in mice by the oral, once-daily administration of 10% v/v ethanol (2 g/kg for one week. Once the animals were withdrawn from alcohol, the efficacy of ASW (200mg/kg and 500mg/kg in comparison with diazepam (1 mg/kg in the attenuation of withdrawal was studied using, pentylenetetrazole (PTZ kindling test for seizure threshold, forced swim test (FST for depression and locomotor activity (LCA in open field test (OFT. 6 hours after the last ethanol administration, seizure threshold was measured in all the groups by administering the convulsant drug, PTZ with a subconvulsive dose of 30 mg/kg i.p. In FST, mice were forced to swim and the total duration of immobility (seconds was measured during the last 4 min of a single 6-min test session. In OFT, number of crossings of the lines marked on the floor was recorded for a period of 5 min. Results: Compared to ethanol group, ASW (500 mg/Kg has suppressed the PTZ kindling seizures in ethanol withdrawal animals [0% convulsion], FST has shown decreased immobility time and OFT has exhibited increase in the number of line crossing activity by mice which may be the consequence of anxiolytic activity of ASW similar to that of diazepam. Conclusions: The present study provides satisfactory evidence to use ASW as a safe and reliable alternative to diazepam in alcohol withdrawal conditions.

  5. Clinical management of alcohol withdrawal: A systematic review

    Full Text Available Alcohol withdrawal is commonly encountered in general hospital settings. It forms a major part of referrals received by a consultation-liaison psychiatrist. This article aims to review the evidence base for appropriate clinical management of the alcohol withdrawal syndrome. We searched Pubmed for articles published in English on pharmacological management of alcohol withdrawal in humans with no limit on the date of publication. Articles not relevant to clinical management were excluded based on the titles and abstract available. Full-text articles were obtained from this list and the cross-references. There were four meta-analyses, 9 systematic reviews, 26 review articles and other type of publications like textbooks. Alcohol withdrawal syndrome is a clinical diagnosis. It may vary in severity. Complicated alcohol withdrawal presents with hallucinations, seizures or delirium tremens. Benzodiazepines have the best evidence base in the treatment of alcohol withdrawal, followed by anticonvulsants. Clinical institutes withdrawal assessment-alcohol revised is useful with pitfalls in patients with medical comorbidities. Evidence favors an approach of symptom-monitored loading for severe withdrawals where an initial dose is guided by risk factors for complicated withdrawals and further dosing may be guided by withdrawal severity. Supportive care and use of vitamins is also discussed.

    may die from these seizures. A literature study was performed of deaths due to alcohol-induced seizures, either during withdrawal or as late-onset seizures where the aetiology was established as long time alcohol abuse and a necropsy had shown no other possible cause of death than a seizure. RESULTS......: It was not possible to find any well-documented cases. It is, however, difficult to compare cases in the literature, as there is no generally accepted classification or nomenclature of seizures related to alcohol abuse....... aetiologies, but in police reports a person known to have seizures is most likely to be reported as suffering from epilepsy. It is a well-known fact that alcoholics have seizures either due to "alcohol-induced epilepsy" or due to withdrawal from drinking. It also seems to be generally accepted that alcoholics...

  7. Alcohol Withdrawal Mimicking Organophosphate Poisoning

    Full Text Available Organophosphates, which can cause occupational poisoning due to inappropriate personal protective measures, are widely used insecticides in agricultural regions of southern Turkey. Therefore, the classical clinical findings of this cholinergic poisoning are myosis, excessive secretions, bradicardia and fasciculations are easy to be recognized by local medical stuff. Diseases and conditions related to alcoholism such as mental and social impairments, coma, toxicity, withdrawal, and delirium are frequent causes of emergency visits of chronic alcoholic patients. Here we present a case diagnosed and treated as organophosphate poisoning although it was an alcohol withdrawal in the beginning and became delirium tremens, due to similar symptoms.

    Full Text Available Aim: The aim of this study is to characterize the clinical profile of patients with alcohol related seizures (ARS and to identify the prevalence of idiopathic generalized epilepsy (IGE in the same. Materials and Methods: 100 consecutive male patients presenting to a tertiary care center in South India with new onset ARS were analyzed with alcohol use disorders identification test (AUDIT score. All underwent 19 channel digital scalp electroencephalography (EEG and at least computed tomography (CT scan. Results: A total of 27 patients (27% who had cortical atrophy on CT had a mean duration of alcohol intake of 23.62 years compared with 14.55 years in patients with no cortical atrophy (P < 0.001. Twenty-two patients (22% had clustering in the current episode of whom 18 had cortical atrophy. Nearly, 88% patients had generalized tonic clonic seizures while 12% who had partial seizures underwent magnetic resonance imaging (MRI, which identified frontal focal cortical dysplasia in one. Mean lifetime duration of alcohol intake in patients presenting with seizures within 6 hours (6H-gp of intake of alcohol was significantly lower (P = 0.029. One patient in the 6H-gp with no withdrawal symptoms had EEG evidence for IGE and had a lower AUDIT score compared with the rest. Conclusion: CT evidence of cortical atrophy is related to the duration of alcohol intake and portends an increased risk for clustering. Partial seizures can be a presenting feature of ARS and those patients may benefit from MRI to identify underlying symptomatic localization related epilepsy (8.3% of partial seizures. IGE is more likely in patients presenting with ARS within first 6 hours especially if they do not have alcohol withdrawal symptoms and scalp EEG is helpful to identify this small subgroup (~1% who may require long-term anti-epileptic medication.

  11. Diazepam in the Treatment of Moderate to Severe Alcohol Withdrawal. (United States)

    Weintraub, Steven J


    Benzodiazepines ameliorate or prevent the symptoms and complications of moderate to severe alcohol withdrawal, which can include autonomic hyperactivity, agitation, combativeness, hallucinations, seizures, delirium, and death. The benzodiazepines most commonly used for this purpose are lorazepam, chlordiazepoxide, oxazepam, and diazepam. It is widely asserted that no member of this group is superior to the others for treatment of alcohol withdrawal. However, of these, diazepam has the shortest time to peak effect, which facilitates both rapid control of symptoms and accurate titration to avoid over-sedation. Furthermore, diazepam and its active metabolite, desmethyldiazepam, have the longest elimination half-lives, so their levels decrease in a gradual, self-tapering manner, resulting in a smoother withdrawal, i.e., a lower incidence and severity of both breakthrough symptoms and rebound phenomena, including a possibly decreased seizure risk. Importantly, the fear of increased risk of over-sedation with diazepam compared with other benzodiazepines is based on a misunderstanding of its pharmacokinetics and is unfounded. Similarly, the notion that diazepam should be avoided in patients with liver disease and elderly patients to avoid prolonged over-sedation is based on no more than conjecture. In fact, there is clinical evidence that diazepam is safe for the treatment of alcohol withdrawal in these patients when administered using a simple symptom-based approach. There is one instance in which diazepam should not be used: when intramuscular administration is the only option, the lipophilicity of diazepam can result in slow absorption-either lorazepam or, when rapid control of symptoms is required, midazolam should be used. The comparative pharmacokinetics of the benzodiazepines used in the treatment of alcohol withdrawal together with a comprehensive review of the literature on their use strongly suggest that diazepam should be the preferred benzodiazepine for the

  12. A 'symptom-triggered' approach to alcohol withdrawal management. (United States)

    Murdoch, Jay; Marsden, Janet

    In acute hospital settings, alcohol withdrawal often causes significant management problems and complicates a wide variety of concurrent conditions, placing a huge burden on the NHS. A significant number of critical incidents around patients who were undergoing detoxification in a general hospital setting led to the need for a project to implement and evaluate an evidence-based approach to the management of alcohol detoxification-a project that included a pre-intervention case note audit, the implementation of an evidence-based symptom-triggered detoxification protocol, and a post-intervention case note audit. This change in practice resulted in an average reduction of almost 60% in length of hospital stay and a 66% reduction in the amount of chlordiazepoxide used in detoxification, as well as highlighting that 10% of the sample group did not display any signs of withdrawal and did not require any medication. Even with these reductions, no patient post-intervention developed any severe signs of withdrawal phenomena, such as seizures or delirium tremens. The savings to the trust (The Pennine Acute Hospital Trust) are obvious,but the development of a consistent, quality service will lead to fewer long-term negative effects for patients that can be caused by detoxification. This work is a project evaluation of a locally implemented strategy, which, it was hypothesised,would improve care by providing an individualised treatment plan for the management of alcohol withdrawal symptoms.

    Christiana Care Health System implemented a Care Management Guideline for Alcohol Withdrawal Symptom Management, which provided direction for inpatient screening for alcohol withdrawal risk, assessment, and treatment. Nurses educated on its use expressed confusion with the use of the assessment tools, pharmacokinetics, and pathophysiology of alcohol withdrawal and delirium tremens. Reeducation was provided by nursing professional development specialists. Pre- and postsurveys revealed that nurses were more confident in caring for patients with alcohol withdrawal.

  16. Comparison of two oral symptom-triggered pharmacological inpatient treatments of acute alcohol withdrawal: clomethiazole vs. clonazepam. (United States)

    Bonnet, Udo; Lensing, Maresa; Specka, Michael; Scherbaum, Norbert


    To compare two inpatient symptom-triggered pharmacological treatments of acute alcohol withdrawal (AWS) (clomethiazole vs. clonazepam). Prospective observational comparison within a quality improvement project. Because of a need for extra precautions against complications such as seizures and severe respiratory complaints, patients with a history of withdrawal seizures or complications with clomethiazole in their history were automatically assigned to the clonazepam group. The remaining patients were alternately assigned either to the clonazepam group (n = 38 altogether) or the clomethiazole group (n = 36). Rescue medication could consist of adding either extra clonazepam or clomethiazole. Effectiveness was measured by Clinical Global Impression Scale, Revised Clinical Institute Withdrawal Assessment for Alcohol Scale, Mainz Alcohol Withdrawal Scale, Essen Self-Assessment-Alcohol Withdrawal and attrition rate. Safety and tolerability was estimated from adverse clinical events. Secondary outcome values were heart rate, blood and pulse pressure. There were no significant differences between the treatments with respect to primary and secondary effectiveness measures, safety or tolerability or duration of medication treatment. Both reduced the severity of initial withdrawal symptoms below 20% up to the ending of withdrawal medications. No withdrawal seizure or delirium occurred. Both score-driven treatments were equally effective, safe and well tolerated in this setting. This is the first study demonstrating the utility of clonazepam in the treatment of AWS syndrome.

  17. Epidemiological and sociodemographic factors associated with complicated alcohol withdrawal syndrome. (United States)

    To analyse the influence of epidemiological and sociodemographic factors in complicated alcohol withdrawal syndrome (AWS). A multicentre, observational prospective study was conducted on consecutively added patients with AWS hospitalised in internal medicine departments. We recorded sociodemographic, epidemiological, clinical and progression data. Complicated AWS was defined as that which progressed with seizures or delirium tremens. We studied 228 episodes of AWS in 219 patients. The mean age was 54.5 years (SD, 11.5), and 90.8% were men. AWS was the cause for hospitalisation in 39.9% of the patients. Some 27.1% of the cases presented seizures, and 32.4% presented delirium tremens. The daily quantity of alcohol ingested was 17.8 standard drink units (SD, 21.4), with 16.6 years of dependence (SD, 11.3). The pattern of alcohol abuse was regular in 82.8% of the patients. Some 38.4% of the patients were married or had a partner, and 45.6% had children. Some 72.7% of the patients were unemployed or retired. Some 68.5% had only completed primary studies. Some 4.8% consumed cannabis, 5.2% consumed cocaine and 3% consumed opioids. The independent variables related to complicated AWS were consumption of a drug other than alcohol (OR, 5.3; 95% CI 1.5-18.7), low education level (OR, 3.4; 95% CI 1.6-7.3) and hospitalisation for AWS (OR, 2.9; 95% CI 1.5-5.6). The model's receiver operating characteristic area was 0.718 (95% CI 0.643-0.793). Concomitant drug abuse and a low educational level could help identify patients at risk of complicated AWS.

  19. Voluntary wheel running attenuates ethanol withdrawal-induced increases in seizure susceptibility in male and female rats (United States)

    Devaud, Leslie L.; Walls, Shawn A.; McCulley, Walter D.; Rosenwasser, Alan M.


    We recently found that voluntary wheel running attenuated ethanol withdrawal-induced increased susceptibility to chemoconvulsant-induced seizures in male rats. Since female rats recover from ethanol withdrawal (EW) more quickly than male rats across several behavioral measures, this study was designed to determine whether the effects of exercise on EW seizures also exhibited sex differences. Animals were maintained under No-Wheel, Locked-Wheel or Free-Wheel conditions and ethanol was administered by liquid diet for 14 days with control animals pair-fed an isocaloric diet, after which seizure thresholds were determined at 1 day or 3 days of EW. Consistent with previous reports, females ran significantly more than males, regardless of diet condition. Introduction of the ethanol-containing liquid diet dramatically increased running for females during the day (rest) phase, with little impact on night phase activity. Consistent with previous reports, EW increased seizure susceptibility at 1 day in non-exercising males and females and at 3 days in males. These effects were attenuated by access to running wheels in both sexes. We also assessed the effects of sex, ethanol diet and exercise on ethanol clearance following an acute ethanol administration at 1 day EW in a separate set of animals. Blood ethanol concentrations at 30 min post-injection were lower in males, ethanol-exposed animals, and runners, but no interactions among these factors were detected. Interestingly, females displayed more rapid ethanol clearance than males and there were no effects of either diet or wheel access on clearance rates. Taken together, these data suggest that voluntary wheel running during ethanol administration provides protective effects against EW seizures in both males and females. This effect may be mediated, in part, in male, but not female rat, by effects of exercise on early pharmacokinetic contributions. This supports the idea that encouraging alcoholics to exercise may benefit

  20. Acute coronary ischemia during alcohol withdrawal: a case report

    Directory of Open Access Journals (Sweden)

    Sriram Ganeshalingam


    Full Text Available Abstract Introduction The potential of alcohol withdrawal to cause acute coronary events is an area that needs the urgent attention of clinicians and researchers. Case presentation We report the case of a 52-year-old heavy-alcohol-using Sri Lankan man who developed electocardiogram changes suggestive of an acute coronary event during alcohol withdrawal. Despite the patient being asymptomatic, subsequent echocardiogram showed evidence of ischemic myocardial dysfunction. We review the literature on precipitation of myocardial ischemia during alcohol withdrawal and propose possible mechanisms. Conclusions Alcohol withdrawal is a commonly observed phenomenon in hospitals. However, the number of cases reported in the literature of acute coronary events occurring during withdrawal is few. Many cases of acute ischemia or sudden cardiac deaths may be attributed to other well known complications of delirium tremens. This is an area needing the urgent attention of clinicians and epidemiologists.

  1. Intranasal oxytocin blocks alcohol withdrawal in human subjects. (United States)

    Pedersen, Cort A; Smedley, Kelly L; Leserman, Jane; Jarskog, Lars Fredrik; Rau, Shane W; Kampov-Polevoi, Alexei; Casey, Robin L; Fender, Trace; Garbutt, James C


    The neuropeptide, oxytocin (OT), has been reported to block tolerance formation to alcohol and decrease withdrawal symptoms in alcohol-dependent rodents. Numerous recent studies in human subjects indicate that OT administered by the intranasal route penetrates into and exerts effects within the brain. In a randomized, double-blind clinical trial, intranasal OT (24 IU/dose, N = 7) or placebo (N = 4) was given twice daily for 3 days in alcohol-dependent subjects admitted to a research unit for medical detoxification using Clinical Institute Withdrawal Assessment for Alcohol (CIWA) score-driven PRN administration of lorazepam. Subjects rated themselves on the Alcohol Withdrawal Symptom Checklist (AWSC) each time CIWA scores were obtained. Subjects also completed the Penn Alcohol Craving Scale, an Alcohol Craving Visual Analog Scale (ACVAS) and the Profile of Mood States (POMS) on inpatient days 2 and 3. All subjects had drunk heavily each day for at least 2 weeks prior to study and had previously experienced withdrawal upon stopping/decreasing alcohol consumption. OT was superior to placebo in reducing alcohol withdrawal as evidenced by: less total lorazepam required to complete detoxification (3.4 mg [4.7, SD] vs. 16.5 [4.4], p = 0.0015), lower mean CIWA scores on admission day 1 (4.3 [2.3] vs. 11.8 [0.4], p block alcohol withdrawal in human subjects. Our results are consistent with previous findings in rodents that OT inhibits neuroadaptation to and withdrawal from alcohol. OT could have advantages over benzodiazepines in managing alcohol withdrawal because it may reverse rather than maintain sedative-hypnotic tolerance. It will be important to test whether OT treatment is effective in reducing drinking in alcohol-dependent outpatients. Copyright © 2012 by the Research Society on Alcoholism.

  3. Gut microbiota modulates alcohol withdrawal-induced anxiety in mice. (United States)

    Xiao, Hui-Wen; Ge, Chang; Feng, Guo-Xing; Li, Yuan; Luo, Dan; Dong, Jia-Li; Li, Hang; Wang, Haichao; Cui, Ming; Fan, Sai-Jun


    Excessive alcohol consumption remains a major public health problem that affects millions of people worldwide. Accumulative experimental evidence has suggested an important involvement of gut microbiota in the modulation of host's immunological and neurological functions. However, it is previously unknown whether enteric microbiota is implicated in the formation of alcohol withdrawal-induced anxiety. Using a murine model of chronic alcoholism and withdrawal, we examined the impact of alcohol consumption on the possible alterations of gut microbiota as well as alcohol withdrawal-induced anxiety and behavior changes. The 16S rRNA sequencing revealed that alcohol consumption did not alter the abundance of bacteria, but markedly changed the composition of gut microbiota. Moreover, the transplantation of enteric microbes from alcohol-fed mice to normal healthy controls remarkably shaped the composition of gut bacteria, and elicited behavioral signs of alcohol withdrawal-induced anxiety. Using quantitative real-time polymerase chain reaction, we further confirmed that the expression of genes implicated in alcohol addiction, BDNF, CRHR1 and OPRM1, was also altered by transplantation of gut microbes from alcohol-exposed donors. Collectively, our findings suggested a possibility that the alterations of gut microbiota composition might contribute to the development of alcohol withdrawal-induced anxiety, and reveal potentially new etiologies for treating alcohol addiction.

  4. An alcohol withdrawal test battery measuring multiple behavioral symptoms in mice. (United States)

    Metten, Pamela; Schlumbohm, Jason P; Huang, Lawrence C; Greenberg, Gian D; Hack, Wyatt R; Spence, Stephanie E; Crabbe, John C


    Despite acceptance that risk for alcohol-use disorder (AUD) has a large genetic component, the identification of genes underlying various components of risk for AUD has been hampered in humans, in part by the heterogeneity of expression of the phenotype. One aspect of AUD is physical dependence. Alcohol withdrawal is a serious consequence of alcohol dependence with multiple symptoms, many of which are seen in multiple species, and can be experienced over a wide-ranging time course. In the present three studies, we developed a battery of withdrawal tests in mice, examining behavioral symptoms from multiple domains that could be measured over time. To permit eventual use of the battery in different strains of mice, we used male and female mice of a genetically heterogeneous stock developed from intercrossing eight inbred strains. Withdrawal symptoms were assessed using commonly used tests after administration of ethanol in vapor for 72 continuous hours. We found significant effects of ethanol withdrawal versus air-breathing controls on nearly all symptoms, spanning 4 days following ethanol vapor inhalation. Withdrawal produced hypothermia, greater neurohyperexcitability (seizures and tremor), anxiety-like behaviors using an apparatus (such as reduced transitions between light and dark compartments), anhedonia (reduced sucrose preference), Straub tail, backward walking, and reductions in activity; however, there were no changes in thermal pain sensitivity, hyper-reactivity to handling, or anxiety-like emergence behaviors in other apparatus. Using these data, we constructed a refined battery of withdrawal tests. Individual differences in severity of withdrawal among different tests were weakly correlated at best. This battery should be useful for identifying genetic influences on particular withdrawal behaviors, which should reflect the influences of different constellations of genes.

  5. [Comparison of Two Symptom-Triggered Treatments for Alcohol Withdrawal: HAES vs. SAB-P]. (United States)

    Holzbach, R; Ihlow, C; Takla, T; Kemper, U; Naber, D


    For alcohol withdrawal during hospitalization, often a medication as means for withdrawal needs to be chosen. Modern, score-controlled processes that can be used by the nursing staff after instruction by physicians are frequently not used and even unknown in hospitals. One reason for this is that some of the scores require checking several criteria and are therefore more time-consuming and complicated than use of a fixed-dosage strategy. The SAB-P and HAES are short with only 6 items that can be checked by the nursing staff. Safety of the Hamburg Alcohol Withdrawal Scale (Hamburger Alkoholentzugs-Skala (HAES)) was analyzed retrospectively and prospectively with regard to score-controlled alcohol-withdrawal treatment after rating by the nurse staff (Scoregesteuerte Alkoholentzugsbehandlung nach Rating durch das Pflegepersonal (SAB-P)). Incidence of complications in patients treated with SAB-P and HAES was nearly similar with 1% start of delirium and 3% seizures (SAB-P) and 0.5 to 1.5% start of delirium and 0 to 0.5% seizures in the HAES group. With both scales it was possible to start medical treatment while still under falling alcohol levels (0.93 and 0.91%, respectively). Medication dosage was initially higher using the HAES, so that the time needed to monitor withdrawal symptoms could be reduced (3.8 vs. 3.1 days). Using a score-controlled strategy for alcohol withdrawal leads to a lower complication rate than found in literature. The structured procedure was helpful for the nursing staff as well as for the physicians. SAB-P as well as HAES made withdrawal for the patients more comfortable and led to fewer complaints. Because of rapid reaction and faster symptom reduction of HAES, there was less time necessary for monitoring. Simple handling, clomethiazol, oxazepam or diazepam as applicable medication and clear documentation are the advantages of HAES. © Georg Thieme Verlag KG Stuttgart · New York.

  6. Ketogenic Diet Suppresses Alcohol Withdrawal Syndrome in Rats. (United States)

    Dencker, Ditte; Molander, Anna; Thomsen, Morgane; Schlumberger, Chantal; Wortwein, Gitta; Weikop, Pia; Benveniste, Helene; Volkow, Nora D; Fink-Jensen, Anders


    Alcohol use disorder is underdiagnosed and undertreated, and up to 50% of alcohol-abstinent patients diagnosed with alcohol dependence relapse within the first year of treatment. Current treatments for the maintenance of alcohol abstinence in patients with alcohol use disorder have limited efficacy, and there is an urgent need for novel treatment strategies. Decreased cerebral glucose metabolism and increased brain uptake of acetate were recently reported in heavy drinkers, relative to controls. Given the switch of metabolic fuel from glucose to acetate in the alcohol-dependent brain, we investigated the potential therapeutic benefit of a ketogenic diet in managing alcohol withdrawal symptoms during detoxification. Male Sprague Dawley rats fed either ketogenic or regular diet were administered ethanol or water orally, twice daily for 6 days while the diet conditions were maintained. Abstinence symptoms were rated 6, 24, 48, and 72 hours after the last alcohol administration. Maintenance on a ketogenic diet caused a significant decrease in the alcohol withdrawal symptoms' "rigidity" and "irritability." Our preclinical pilot study suggests that a ketogenic diet may be a novel approach for treating alcohol withdrawal symptoms in humans. Copyright © 2017 by the Research Society on Alcoholism.

  8. Nicotinic Mechanisms Modulate Ethanol Withdrawal and Modify Time Course and Symptoms Severity of Simultaneous Withdrawal from Alcohol and Nicotine. (United States)

    Perez, Erika; Quijano-Cardé, Natalia; De Biasi, Mariella


    Alcohol and nicotine are among the top causes of preventable death in the United States. Unfortunately, people who are dependent on alcohol are more likely to smoke than individuals in the general population. Similarly, smokers are more likely to abuse alcohol. Alcohol and nicotine codependence affects health in many ways and leads to poorer treatment outcomes in subjects who want to quit. This study examined the interaction of alcohol and nicotine during withdrawal and compared abstinence symptoms during withdrawal from one of the two drugs only vs both. Our results indicate that simultaneous withdrawal from alcohol and nicotine produces physical symptoms that are more severe and last longer than those experienced during withdrawal from one of the two drugs alone. In animals experiencing withdrawal after chronic ethanol treatment, acute nicotine exposure was sufficient to prevent abstinence symptoms. Similarly, symptoms were prevented when alcohol was injected acutely in mice undergoing nicotine withdrawal. These experiments provide evidence for the involvement of the nicotinic cholinergic system in alcohol withdrawal. Furthermore, the outcomes of intracranial microinfusions of mecamylamine, a nonselective nicotinic receptor antagonist, highlight a major role for the nicotinic receptors expressed in medial habenula and interpeduncular nucleus during withdrawal. Overall, the data support the notion that modulating the nicotinic cholinergic system might help to maintain long-term abstinence from alcohol.

  9. Effects of alcohol dependence and withdrawal on stress responsiveness and alcohol consumption. (United States)

    Becker, Howard C


    A complex relationship exists between alcohol-drinking behavior and stress. Alcohol has anxiety-reducing properties and can relieve stress, while at the same time acting as a stressor and activating the body's stress response systems. In particular, chronic alcohol exposure and withdrawal can profoundly disturb the function of the body's neuroendocrine stress response system, the hypothalamic-pituitary-adrenocortical (HPA) axis. A hormone, corticotropin-releasing factor (CRF), which is produced and released from the hypothalamus and activates the pituitary in response to stress, plays a central role in the relationship between stress and alcohol dependence and withdrawal. Chronic alcohol exposure and withdrawal lead to changes in CRF activity both within the HPA axis and in extrahypothalamic brain sites. This may mediate the emergence of certain withdrawal symptoms, which in turn influence the susceptibility to relapse. Alcohol-related dysregulation of the HPA axis and altered CRF activity within brain stress-reward circuitry also may play a role in the escalation of alcohol consumption in alcohol-dependent individuals. Numerous mechanisms have been suggested to contribute to the relationship between alcohol dependence, stress, and drinking behavior. These include the stress hormones released by the adrenal glands in response to HPA axis activation (i.e., corticosteroids), neuromodulators known as neuroactive steroids, CRF, the neurotransmitter norepinephrine, and other stress-related molecules.

    Rahul Mohanrao Band


    Full Text Available Background: Alcohol withdrawal syndrome (AWS is one of the most serious complications associated with chronic alcoholism. Sudden deaths are not uncommon in AWS. In severe stages of AWS, delirium tremens (DT occurs, which is characterized with agitation, global confusion, disorientation, visual and auditory hallucinations in addition to autonomic hyperactivity. Case report: A 30-year old man, chronic and heavy alcohol drinker for 10 years, abstained from alcohol for 3 days. Consequently, he started having palpitations, sweating and tremors. A day later, he was found having hallucinations and delirium. The patient was immediately transferred to the hospital. On admission, he was stuporous and had difficulty in breathing. He developed generalized seizures later on. He was successfully intubated, but there was bleeding through it. The patient’s condition deteriorated very rapidly and he died within two hours. After death, his body was transferred to forensic department. In autopsy, gastrointestinal tract was found to be intact. Massive pulmonary hemorrhage was present on cut section. Liver was found to be with yellowish discoloration and early cirrhotic changes. In heart, left ventricular hypertrophy with narrowed lumen was present and coronary arteries were patent. Discussion: Alcoholism is associated with liver dysfunction and especially in final phases with cirrhosis. Hence and due to resultant coagulopathy, patients are vulnerable to internal bleedings. Hypertrophic cardiomyopathy also occurs in chronic alcoholics. Therefore, we can speculate that our patient developed pulmonary hemorrhage as a result of combined effect of coagulopathy secondary to cirrhosis, alveolar damage (seizure and artificial ventilation and congestive heart failure. Conclusion: For a patient with delirium, convulsions, respiratory distress and coagulopathy, diagnosis of DT should be kept in mind.

  12. Psychotropic analgesic nitrous oxide for alcoholic withdrawal states. (United States)

    Gillman, M A; Lichtigfeld, F J; Young, T N


    Alcoholism is a global problem with 5-10% of the world's population demonstrating alcohol-related diseases. One of the most severe consequences of alcohol dependence is the withdrawal syndrome, for which benzodiazepines are the most popular current treatment. An alternative method to benzodiazepine employs psychotropic analgesic nitrous oxide (PAN). To assess the effects of PAN for treating alcohol withdrawal states We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 2, 2005), MEDLINE, EMBASE, CINAHL (all to May 2005). We scanned internet websites, reference lists of relevant articles and abstracts of the international Conferences on Alcoholism. We contacted researchers in the field and industry to identify unpublished trials. No language and publication restrictions. Randomised controlled trials including voluntary participants dependent on alcohol. PAN was compared to oxygen and/or benzodiazepine regimens. Two authors independently assessed the methodological quality of the trials and extracted data. Five studies, 212 participants, were included. PAN showed improvement of symptoms (RR 1.35; 95% CI 1.01 to 1.79), of the amount and duration of sedative medication and of psychomotor function (WMD -8.71; 95% CI -13.71 to -3.71). At one hour post intervention, no significant differences were found for depression (WMD -2.40; 95% CI -8.70 to 3.89) and anxiety (WMD -3.70; 95% CI -10.53 to 3.12). None of the included studies reported any significant adverse effects of any treatment. Results indicate that PAN may be an effective treatment of the mild to moderate alcoholic withdrawal state. The rapidity of the therapeutic effect of PAN therapy coupled with the minimal sedative requirements, may enable patients to enter the psychological treatment phase more quickly than those on sedative regimens, accelerating the patients recovery. Our review does not provide strong evidence due to the small sample sizes of the included trials

  14. Baclofen as prophylaxis and treatment for alcohol withdrawal: a retrospective chart review. (United States)

    Stallings, William; Schrader, Stuart


    Current standard of care for alcohol withdrawal is accomplished using benzodiazepines. There are no recommendations for prophylaxis of alcohol withdrawal in high risk populations. Baclofen has been studied for the treatment of alcohol withdrawal, but current research is limited. To determine if baclofen is an effective measure for prophylaxis and treatment of alcohol withdrawal in high risk populations upon admission to hospital wards. Design, Setting, Patients - Retrospective chart review of 42 inpatients at St. Anthony Hospital from November 2004 to April 2005. Patients were included if they were determined to be at risk for alcohol withdrawal. Patients were then divided into categories of prophylactic success versus failure and treatement success versus failure based on DSM-IV criteria for alcohol withdrawal. 17 patients were included in the study. 12 were categorized as prophylactic success and 2 were categorized as prophylactic failure. There was one treatment success and two treatment failures. The result was an 86% prophylactic success rate. Baclofen has potential in the prophylaxis of alcohol withdrawal. It is difficult to determine the clinical significance for the numbers found in this study. There are no prior studies for alcohol prophylaxis to compare what would be an acceptable success rate. Further studies that are double-blinded placebo controlled are needed to support or refute the usefulness of baclofen for alcohol withdrawal.

    Full Text Available Unmanaged sudden withdrawal from the excessive consumption of alcohol (ethanol adversely alters neuronal integrity in vulnerable brain regions such as the cerebellum, hippocampus, or cortex. In addition to well known hyperexcitatory neurotransmissions, ethanol withdrawal (EW provokes the intense generation of reactive oxygen species (ROS and the activation of stress-responding protein kinases, which are the focus of this review article. EW also inflicts mitochondrial membranes/membrane potential, perturbs redox balance, and suppresses mitochondrial enzymes, all of which impair a fundamental function of mitochondria. Moreover, EW acts as an age-provoking stressor. The vulnerable age to EW stress is not necessarily the oldest age and varies depending upon the target molecule of EW. A major female sex steroid, 17β-estradiol (E2, interferes with the EW-induced alteration of oxidative signaling pathways and thereby protects neurons, mitochondria, and behaviors. The current review attempts to provide integrated information at the levels of oxidative signaling mechanisms by which EW provokes brain injuries and E2 protects against it.

    Misra Usha


    Full Text Available A provoked seizure may be due to structural damage (resulting from traumatic brain injury, brain tumor, stroke, tuberculosis, or neurocysticercosis or due to metabolic abnormalities (such as alcohol withdrawal and renal or hepatic failure. This article is a part of the Guidelines for Epilepsy in India. This article reviews the problem of provoked seizure and its management and also provides recommendations based on currently available information. Seizure provoked by metabolic disturbances requires correction of the triggering factors. Benzodiazepines are recommended for treatment of seizure due to alcohol withdrawal; gabapentin for seizure seen in porphyria; and antiepileptic drugs (AED, that are not inducer of hepatic enzymes, in the seizures seen in hepatic dysfunction. In severe traumatic brain injury, with or without seizure, phenytoin (PHT may be given for 7 days. In ischemic or hemorrhagic stroke one may individualize the AED therapy. In cerebral venous sinus thrombosis (CVST, AED may be prescribed if there is seizure or computed tomographic (CT abnormalities or focal weakness; the treatment, in these cases, has to be continued for 1 year. Prophylactic AED is not recommended in cases of brain tumor and neurosurgical procedures and if patient is on an AED it can be stopped after 1 week.

    Fleming Rosanna


    Full Text Available Abstract Background Bupropion HCl is a widely used antidepressant that is known to cause seizures in a dose-dependent manner. Many patients taking antidepressants will consume alcohol, even when advised not to. Previous studies have not shown any interactions between bupropion HCl and alcohol. However, there have been no previous studies examining possible changes in seizure threshold induced by a combination of alcohol and bupropion HCl. Methods Experimentally naïve female Swiss albino mice (10 per group received either single doses of bupropion HCl (ranging from 100 mg/kg to 120 mg/kg or vehicle (0.9% NaCl by intraperitoneal (IP injection in a dose volume of 10 ml/kg, and single-dose ethanol alone (2.5 g/kg, or vehicle, 5 min prior to bupropion dosing. The presence or absence of seizures, the number of seizures, the onset, duration and the intensity of seizures were all recorded for 5 h following the administration of ethanol. Results The results show that administration of IP bupropion HCl alone induced seizures in mice in a dose-dependent manner, with the 120 mg/kg dose having the largest effect. The percentage of convulsing mice were 0%, 20%, 30% and 60% in the 0 (vehicle, 100, 110, and 120 mg/kg dose groups, respectively. Pretreatment with ethanol produced a larger bupropion HCl-induced convulsive effect at all the doses (70% each at 100, 110 and 120 mg/kg and a 10% effect in the ethanol + vehicle only group. The convulsive dose of bupropion HCl required to induce seizures in 50% of mice (CD50, was 116.72 mg/kg for bupropion HCl alone (CI: 107.95, 126.20 and 89.40 mg/kg for ethanol/bupropion HCl (CI: 64.92, 123.10. Conclusion These results show that in mice alcohol lowers the seizure threshold for bupropion-induced seizures. Clinical implications are firstly that there may be an increased risk of seizures in patients consuming alcohol, and secondly that formulations that can release bupropion more readily in alcohol may present additional

  19. Evaluation of clinical practice improvement programs for nurses for the management of alcohol withdrawal in hospitals. (United States)

    Daly, Michelle; Kermode, Stephen; Reilly, David


    The most common alcohol-related chronic condition for hospitalisation is alcohol dependence which can lead to an alcohol withdrawal syndrome (AWS). The aim of this paper is to report on a quality improvement program in an Australian rural area health service for the screening and management of alcohol withdrawal and the effect of two types of nursing education and training approaches: a self-directed competency training package and a more traditional in-service program. The measure of improvement was compliance to nine clinical standards or core competencies for the assessment and treatment of the AWS derived from the Clinical Institute Withdrawal Assessment for Alcohol-Revised (CIWA-Ar) scale and the NSW drug and alcohol withdrawal clinical practice guidelines. An audit of medical records using a standardised protocol for the nine standards was conducted at baseline (n=100) and follow-up (n=340) across eleven hospitals in the area. Results indicated that in three hospitals, where 70 nurses completed the self-directed competency training, there was a higher total compliance score across the nine standards compared to eight hospitals where 238 nurses received the in-service program. The self-directed competency program was also rated highly by nurses who participated in the program. The benefits of self-directed competency training are discussed as well as future recommendations for improving nurse education strategies for managing alcohol withdrawal.

  20. Are Alcohol Anti-relapsing and Alcohol Withdrawal Drugs Useful in Cannabinoid Users? (United States)

    Kleczkowska, Patrycja; Smaga, Irena; Filip, Małgorzata; Bujalska-Zadrozny, Magdalena


    Cannabinoids are still classified as illegal psychoactive drugs despite their broad and increasingly acknowledged therapeutic potential. These substances are most famous for their wide recreational use, particularly among young adults to either alter the state of consciousness, intensify pleasure induced by other psychoactive substances or as an alternative to the previously abused drugs. It is important to emphasize that cannabinoids are often taken together with a variety of medications intended for the treatment of alcohol use disorder (AUD) or alcohol withdrawal syndrome (AWS). These medications include disulfiram, acamprosate, and naltrexone. In this paper, we summarize recent advances in the knowledge of possible beneficial effects and interactions between cannabinoids and drugs commonly used for treatment of AUD and AWS either comorbid or existing as a separate disorder.

    Heberlein, Annemarie; Muschler, Marc; Frieling, Helge; Lenz, Bernd; Wilhelm, Julia; Gröschl, Michael; Kornhuber, Johannes; Bleich, Stefan; Hillemacher, Thomas


    The hypothalamic galanin expression has been associated with increased intake of carbohydrates and fats in preclinical studies. The appetite stimulating effect of galanin is thought to underlie the positive association between alcohol consumption and hypothalamic galanin expression observed in preclinical studies. In this pilot study we investigated alterations in galanin serum levels (33 male patients) in alcohol-dependent patients during alcohol withdrawal (days 1, 7 and 14) in comparison to healthy controls (19 male controls). In order to assess the putative association between appetite regulation, galanin serum levels and alcohol consumption we additionally investigated the serum levels of insulin, glucose and triglycerides. The galanin serum levels on day 1 of alcohol withdrawal were significantly reduced in the alcohol-dependent patients (T=-3.302, p=0.002) and increased significantly from day 1 to day 14 of alcohol withdrawal (F=6.437, p=0.002). We found a significant negative association between the galanin serum levels and alcohol craving measured by the Obsessive Compulsive Drinking Scale (OCDS) (r=-0.449, p=0.009) and the obsessive subscale of the OCDS (r=-0.521, p=0.002) on day 1 of alcohol withdrawal. There was no association between the galanin serum levels and the parameters of energy homeostasis (triglycerides, cholesterol, insulin, and glucose) investigated. Acute alcohol withdrawal was associated with decreased galanin serum levels in this pilot study. There was no association between the galanin serum levels and the parameters of energy homeostasis. Further research of galanin serum levels in active drinkers will be necessary to clarify the putative association between galanin serum levels, appetite regulation and alcohol consumption.

    Debadatta Nayak


    Full Text Available Background: Alcohol dependence is a common social problem which may be associated with other risk factors and co-morbidities. Abrupt cessation of alcohol intake may provoke an acute alcohol withdrawal phase with varying degrees of signs and symptoms. In conventional medical system, specific pharmacological interventions are used for management of Acute Alcohol Withdrawal (AAW. There exists a need to explore safe and holistic treatment of AAW. The present work reports the results of a prospective, observational, exploratory, multicentre trial (2008-2011 to assess the role of Homoeopathy in AAW. Materials and Methods: Individualised Homoeopathy was given to 112 patients reporting with AAW. The clinical assessment was done for 05 days using Clinical Institute Withdrawal Assessment Scale of Alcohol-Revised (CIWA-Ar. Post-withdrawal phase, quality of life of patients was assessed at end of 01 st , 03 rd and 06 th month using World Health Organisation quality of life (WHOQOL- BREF. Results and Analysis: There was a significant decrease in CIWA-Ar mean scores and increase in quality of life score (P < 0.001. The most common remedies used were Arsenicum album, Lycopodium clavatum, Belladonna, Nux vomica and Pulsatilla. Conclusion: The results of current observational pilot study suggest the promising use of Homoeopathy in the management of acute alcohol withdrawal. Further studies with large sample size and rigorous design are warranted.

    The human intestinal microbiota exerts beneficial or harmful effects in several disorders. Many factors, including alcohol consumption, may influence its composition and trigger bacterial translocation. Excessive alcohol consumption increases gut permeability and translocation of endotoxin into peripheral circulation. Although plasma endotoxin concentrations have been measured often, quantitative changes following alcohol withdrawal have never been described in subjects with alcohol use disorder (AUD). The aim of this study was to measure microbial translocation (MT) and gut permeability markers in patients with AUD, to compare these markers to healthy controls (HC) and to monitor markers during the first 6 weeks of abstinence. Sixty-five patients with AUD and hospitalized for alcohol withdrawal were included. Epidemiological, clinical, biological, and addictological data were gathered. Blood samples were collected at baseline, then 3 and 6 weeks after alcohol withdrawal. A hundred healthy volunteers were used as controls. Three markers of MT were monitored in plasma samples: sCD14 and lipopolysaccharide-binding protein (LBP) were quantified using ELISA, and 16S rDNA was quantified using real-time polymerase chain reaction. Zonulin and intestinal fatty acid binding protein (I-FABP) blood levels were also monitored as indirect markers of gut permeability, using ELISA. At baseline, LBP, 16S rDNA, sCD14 and I-FABP markers were significantly higher in patients with AUD than in HC. Six weeks after alcohol withdrawal plasma levels of sCD14 and LBP decreased significantly. Cannabis consumption and body mass index (BMI) before alcohol withdrawal influenced baseline MT levels and the decrease in MT markers after 6 weeks. Finally, markers of MT and gut permeability did not correlate with each other before and after alcohol withdrawal. Before alcohol withdrawal, MT markers were higher in patients with AUD than in HC. After 6 weeks of abstinence, an improvement in MT

    Passiflora incarnata L. (Passifloraceae) has been traditionally used for treatment of anxiety, insomnia, drug addiction, mild infections, and pain. The aim of this study was to investigate the effect of a commercial extract of P. incarnata in the analgesia induced by alcohol withdrawal syndrome in rats. In addition, brain-derived neurotrophic factor and interleukin-10 levels were evaluated in prefrontal cortex, brainstem, and hippocampus. Male adult rats received by oral gavage: (1: water group) water for 19 days, 1 day interval and water (8 days); (2: P. incarnata group) water for 19 days, 1 day interval and P. incarnata 200 mg/kg (8 days); (3: alcohol withdrawal group) alcohol for 19 days, 1 day interval and water (8 days); and (4: P. incarnata in alcohol withdrawal) alcohol for 19 days, 1 day interval and P. incarnata 200 mg/kg (8 days). The tail-flick and hot plate tests were used as nociceptive response measures. Confirming previous study of our group, it was showed that alcohol-treated groups presented an increase in the nociceptive thresholds after alcohol withdrawal, which was reverted by P. incarnata, measured by the hot plate test. Besides, alcohol treatment increased brain-derived neurotrophic factor and interleukin-10 levels in prefrontal cortex, which was not reverted by P. incarnata. Considering these results, the P. incarnata treatment might be a potential therapy in the alcohol withdrawal syndrome. Copyright © 2017 John Wiley & Sons, Ltd.

    Full Text Available Abstract Background Poor quality of sleep among alcoholics and persons undergoing alcohol withdrawal has been described as a possible cause of alcohol relapse. It has been suggested earlier that nitrous oxide gas has a significant effect on the signs of alcohol withdrawal syndrome (AWS and thus might be expected to reduce sleep disturbance during withdrawal. The aim of the present study was to investigate sleep quality during alcohol withdrawal, to evaluate the correlation between sleep quality and the severity of AWS and alcohol craving, and to determine if nitrous oxide treatment does counteract withdrawal's effects on the quality of sleep. Voluntary patients (n = 105 admitted to the A-Clinic detoxification center with AWS were included in the study. The AWS patients were randomly assigned to one of the following 45-minute gas treatments: (1 nitrous oxide/oxygen; (2 normal air/O2; and (3 medical (normal air. The study was single-blind by design. Sleep quality was assessed after these treatments during the inpatient period; sleep time, sleep efficiency and the fragmentation of sleep were recorded by wrist-worn actigraphs. Severity of AWS was evaluated by the Clinical Institute Withdrawal Assessment of Alcohol Scale (CIWA-Ar and that of alcohol dependence and craving by the Obsessive Compulsive Drinking Scale [OCDS] and the Severity of Alcohol Dependence Data (SADD questionnaire. Results The fragmentation index and the time awake while in bed were both much above the reference values for the Finnish population. These values reflect the restless and disturbed night sleep of the subjects. The only statistically significant effects between the treatment groups were found in the correlations of CIWA-Ar (severity of AWS scores, OCDS-scores (alcohol craving and coffee consumption, all of which were positively associated with movement time and negatively with total sleep time and sleep efficiency.

    Motaghinejad, Majid; Bangash, Mohammad Yasan; Motaghinejad, Ozra


    Relieving withdrawal and post-abstinence syndrome of alcoholism is one of the major strategies in the treatment of alcohol addicted patients. Diazepam, chlordiazepoxide, and topiramate are the approved medications that were used for this object. To assess the role of non-pharmacologic therapy in the management of alcohol withdrawal syndrome, we analyzed effects of forced exercise by treadmill on alcohol dependent mice as an animal model. A total of 60 adult male mice were divided into 5 groups, from which 4 groups became dependent to alcohol (2 g/kg/day) for 15 days. From day 16, treatment groups were treated by diazepam (0.5mg/kg), forced exercise, and diazepam (0.5 mg/kg) concurrent with forced exercise for two weeks; And the positive control group received same dose of alcohol (2 g/kg/day) for two weeks. The negative control group received normal saline for four weeks. Finally, on day 31, all animals were observed for withdrawal signs, and Alcohol Total Withdrawal Score (ATWS) was determined. Blood cortisol levels were measured in non-fasting situations as well. Present findings showed that ATWS significantly decrease in all treatment groups in comparison with positive control group (Pdiazepam and treated by forced exercise and Pdiazepam + forced exercise). Moreover, blood cortisol level significantly decreased in all treatment groups (P<0.001). This study suggested that forced exercise and physical activity can be useful as adjunct therapy in alcoholism and can ameliorate side effects and stress situation of withdrawal syndrome periods.

  9. [Evaluation of selected socioeconomic factors in patients with acute ethanol intoxication and alcohol withdrawal syndrome]. (United States)

    Lukasik-Głębocka, Magdalena; Sommerfeld, Karina


    Ethanol is commonly overused psychoactive substance in Poland and all around the world. It causes addiction, which occurs as a result of its chronic administration. One of the main symptoms of addiction is hunger due to psychoactive substance that prevents interruption of its adoption and contributes to relapse drinking. Acute poisoning with ethyl alcohol and alcohol withdrawal syndrome are diseases causing a potential danger to life. The prevalence of use and abuse of alcoholic beverages is a potential risk, causing health problems, including permanent damage of the central and peripheral nervous system and socio-economic problems. The aim of this study is to analyze certain aspects of the socio-economic situation of the patients hospitalized in the Department of Toxicology in Raszeja City Hospital in Poznan due to acute ethanol intoxication or alcohol withdrawal syndrome in 2010. 299 patients history was evaluated, among which 161 were treated for acute intoxication with ethanol and 138 due to alcohol withdrawal syndrome. Objects of interest were elements of subjective tests including: marital status of patients, their education and professional activity and the problem of homelessness. The study group consisted of 299 patients in age from 16 to 77 years, hospitalized in the Department of Toxicology in Raszeja City Hospital in Poznan due to acute ethanol intoxication or alcohol withdrawal syndrome. It was found that the largest group consisted of patients remaining married (42.81%) and unmarried (30.43%). Alcohol abuse affects people of all levels of education. In the present study, most patients had a vocational education (37.79%) and medium (23.08%). Patients were analyzed in terms of economic activity, among which about 40% were unemployed. In the whole group more than 10% of those were homeless. Ethyl alcohol intoxication and alcohol withdrawal represents a significant hazard. As a result of reliance, patients lose control of alcohol consumption and they

    This single site retrospective observational study assessed the evolution of sedation therapy for severe alcohol withdrawal syndrome in the intensive care unit. Patient records for 2 intervals were reviewed: Interval 1, which included 87 intensive care unit patients admitted January 2005 through September 2007, for whom benzodiazedpine monotherapy was utilized; and Interval 2, January 2010 through December 2010, for whom 54 of 84 (64.3%) intensive care unit patients, including all those intubated, received adjunctive agents, including dexmedetomidine or propofol. Clinical management was similar for both intervals, as well as prevalence of alcohol withdrawal syndrome versus total adult hospital admissions and comorbid conditions. Overall, respiratory failure (53 versus 39%), seizures (36 versus 18%), and pneumonia (51 versus 38%) were less frequent during Interval 2 (all p intensive care unit admission are excluded, the prevalence of these complications was similar (p = ns) for Interval 1 and Interval 2. Intensive care unit and hospital length of stay were not altered by adjunctive therapy, which was typically employed for more severely affected patients. High intensity sedation with adjunctive drugs led to few cardiovascular adverse events and may have facilitated management, but did not alter intensive care unit course of severe alcohol withdrawal syndrome.

    Long-term use of benzodiazepine-type drugs may lead to physical dependence, manifested by withdrawal syndrome after abrupt cessation of treatment. The aim of the present study was to investigate the influence of duration of treatment, as well as the role of α1-containing GABAA receptors, in development of physical dependence to diazepam, assessed through the level of anxiety and susceptibility to pentylenetetrazole (PTZ)-induced seizures, 24h after withdrawal from protracted treatment in rats. Withdrawal of 2mg/kg diazepam after 28, but not after 14 or 21 days of administration led to an anxiety-like behavior in the elevated plus maze. Antagonism of the diazepam effects at α1-containing GABAA receptors, achieved by daily administration of the neutral modulator βCCt (5mg/kg), did not affect the anxiety level during withdrawal. An increased susceptibility to PTZ-induced seizures was observed during diazepam withdrawal after 21 and 28 days of treatment. Daily co-administration of βCCt further decreased the PTZ-seizure threshold after 21 days of treatment, whilst it prevented the diazepam withdrawal-elicited decrease of the PTZ threshold after 28 days of treatment. In conclusion, the current study suggests that the role of α1-containing GABAA receptors in mediating the development of physical dependence may vary based on the effect being studied and duration of protracted treatment. Moreover, the present data supports previous findings that the lack of activity at α1-containing GABAA receptors is not sufficient to eliminate physical dependence liability of ligands of the benzodiazepine type.

  12. Gabapentin's acute effect on mood profile -- a controlled study on patients with alcohol withdrawal. (United States)

    Bonnet, Udo; Specka, Michael; Leweke, F Markus; Nyhuis, Peter; Banger, Markus


    Delayed beneficial effects of gabapentin on mood were frequently reported in various patient populations. This is the first controlled study which addressed acute effects of gabapentin on mood. Analysis of the German version of Profile of Mood States (POMS) throughout a randomised placebo-controlled, double-blinded study of gabapentin on acute alcohol withdrawal [Bonnet, U., Banger, M., Leweke, F.M., Specka, M., Müller, B.W., Hashemi, T., Nyhuis, P.W., Kutscher, S., Burtscheidt, W., Gastpar, M. 2003. Treatment of acute alcohol withdrawal with gabapentin -- results from a controlled two-center trial. J Clin Psychopharmacol 23, 514-519]. In addition, subjective severity of alcohol withdrawal was determined by the Essen Self-Assessment of Alcohol Withdrawal Scale (ESA) to control effects of concurrent withdrawal on POMS. Ratings were performed at intake (baseline), day 1 (study medication 400 mg q.i.d.), day 2 (study medication 400 mg q.i.d.) and day 7 (no study medication). Analyses could be performed on 46 out of 59 randomised subjects. Within the first two days of the study, a significant stronger increase in the POMS-vigour subscore occurred in the gabapentin group. A subgroup analysis suggests that gabapentin's effect on vigour largely results from a stronger improvement of vigour in a small group of 11 patients with co-morbid mild depression (according to ICD-10: dysthymia or depressive adjustment disorder). There were no significant differences between the treatment groups regarding the other POMS-subscores (dejection, fatigue, anger) ruling out an overall fast effect on mood. Moreover, ESA-measures were not significantly altered indicating a missing effect of 400 mg gabapentin q.i.d. on acute alcohol withdrawal itself. After tapering off study medication, no more significant differences between gabapentin and placebo group were observed on vigour, strongly suggesting that the initial effect results from a pharmacological gabapentin action. Gabapentin

    Full Text Available Paul Schneider1, Vicki A Nejtek2,3, Cheryl Hurd2,31Green Oaks Behavioral Health Care Services, Dallas, 2University of North Texas Health Science Center, Fort Worth, 3John Peter Smith Health Network, Fort Worth, Texas, USAAbstract: Demyelination is a hallmark of central pontine myelinolysis (CPM. Neuropsychiatric manifestations of this condition include weakness, quadriplegia, pseudobulbar palsy, mood changes, psychosis, and cognitive disturbances. These psychiatric symptoms are also associated with schizophrenia and alcohol withdrawal. Thus, it is clinically relevant to differentiate between CPM, schizophrenia, and alcohol withdrawal as the treatment and prognostic outcomes for each diagnosis are distinct. We present a series of events that led to a misdiagnosis of a patient admitted to the medical emergency center presenting with confusion, psychomotor agitation, and delirium who was first diagnosed with schizophrenia and alcohol withdrawal by emergency medical physicians and later discovered by the psychiatric consult team to have CPM. With a thorough psychiatric evaluation, a review of the laboratory results first showing mild hyponatremia (127 mmol/L, subsequent hypernatremia (154 mmol/L, and magnetic resonance brain imaging, psychiatrists concluded that CPM was the primary diagnosis underlying the observed neuropsychopathology. This patient has mild impairments in mood, cognition, and motor skills that remain 12 months after her emergency-center admission. This case report reminds emergency clinicians that abnormal sodium metabolism can have long-term and devastating psychopathological and neurological consequences. Differentiating between CPM, schizophrenia, and alcohol withdrawal using neuroimaging techniques and preventing the risks for CPM using slow sodium correction are paramount.Keywords: MRI, alcohol, schizophrenia, central pontine myelinolysis, hyponatremia

  14. Diverse autonomic regulation of pupillary function and the cardiovascular system during alcohol withdrawal. (United States)

    Jochum, Thomas; Hoyme, Johannes; Schulz, Steffen; Weißenfels, Markus; Voss, Andreas; Bär, Karl-Jürgen


    Previous research indicated the complexity of autonomic dysfunction during acute alcohol withdrawal. This study aimed to investigate the pupillary light reflex as an indicator of midbrain and brainstem regulatory systems in relation to cardiovascular autonomic function. Thirty male patients were included in the study. They were investigated during acute alcohol withdrawal syndrome and 24h later during clomethiazole treatment and compared to healthy controls. Parameters of pupillary light reflex of both eyes as well as heart rate variability, blood pressure variability and baroreflex sensitivity (BRS) were studied. We observed significantly reduced sympathetic (small diameter, e.g., left eye: 5.00 in patients vs. 5.91 mm in controls) and vagal modulation (e.g., prolonged latencies, left eye: 0.28 vs. 0.26 ms) regarding both pupils during acute alcohol withdrawal syndrome. Cardiovascular parameters showed reduced vagal modulation (e.g., b-slope of BRS: 7. 57 vs. 13.59 ms/mm Hg) and mixed results for sympathetic influence. After 24h, autonomic dysfunction improved significantly, both for the pupils (e.g., left diameter: 5.38 mm) and the heart (e.g., b-slope of BRS: 9.34 ms/mm Hg). While parameters obtained from the pupil correlated with cardiac autonomic function (e.g, BRS and left diameter: r=0.564) in healthy controls, no such pattern was observed in patients. Results obtained from the pupil during acute alcohol withdrawal do not simply mirror autonomic dysfunction regarding the heart. Pupillary and cardiovascular changes after 24h indicate state dependencies of the results. The findings are discussed with respect to autonomic mechanisms and potentially involved brain regions.

  15. Clinical Evolution of Central Pontine Myelinolysis in a Patient with Alcohol Withdrawal: A Blurred Clinical Horizon

    Directory of Open Access Journals (Sweden)

    Abdul S. Mohammed


    Full Text Available Central pontine myelinolysis (CPM, a potentially fatal and debilitating neurological condition, was first described in 1959 in a study on alcoholic and malnourished patients. It is a condition most frequently related to rapid correction of hyponatremia. Chronic alcoholism associated CPM tends to be benign with a favorable prognosis compared to CPM secondary to rapid correction of hyponatremia. We describe a normonatremic, alcoholic patient who presented with CPM after a rapid rise in his sodium levels. Our case illustrates the fact that CPM can manifest even in patients who are normonatremic at baseline. Rapid rises in sodium levels should be promptly reversed before clinical symptoms manifest in patient with risk factors for CPM irrespective of their baseline sodium levels. Furthermore, clinical evolution of CPM can be difficult to discern from the natural course of alcohol withdrawal delirium, requiring astuteness and maintenance of a high degree of clinical suspicion on the part of the physician.

  16. Cost-effectiveness analysis of baclofen and chlordiazepoxide in uncomplicated alcohol-withdrawal syndrome (United States)

    Reddy, Vikram K.; Girish, K.; Lakshmi, Pandit; Vijendra, R.; Kumar, Ajay; Harsha, R.


    Objectives: Benzodiazepines (BZDs) are the first-line drugs in alcohol-withdrawal syndrome (AWS). Baclofen, a gamma-aminobutyric acidB (GABAB) agonist, controls withdrawal symptoms without causing significant adverse effects. The objective of this study was to compare the cost-effectiveness of baclofen and chlordiazepoxide in the management of uncomplicated AWS. Materials and Methods: This was a randomized, open label, standard controlled, parallel group study of cost-effectiveness analysis (CEA) of baclofen and chlordiazepoxide in 60 participants with uncomplicated AWS. Clinical efficacy was measured by the Clinical Institute Withdrawal Assessment for alcohol (CIWA-Ar) scores. Lorazepam was used as supplement medication if withdrawal symptoms could not be controlled effectively by the study drugs alone. Both direct and indirect medical costs were considered and the CEA was analyzed in both patient's perspective and third-party perspective. Results: The average cost-effectiveness ratio (ACER) in patient's perspective of baclofen and chlordiazepoxide was Rs. 5,308.61 and Rs. 2,951.95 per symptom-free day, respectively. The ACER in third-party perspective of baclofen and chlordiazepoxide was Rs. 895.01 and Rs. 476.29 per symptom-free day, respectively. Participants on chlordiazepoxide had more number of symptom-free days when compared with the baclofen group on analysis by Mann-Whitney test (U = 253.50, P = 0.03). Conclusion: Both study drugs provided relief of withdrawal symptoms. Chlordiazepoxide was more cost-effective than baclofen. Baclofen was relatively less effective and more expensive than chlordiazepoxide. PMID:25097273

  17. Alcohol withdrawal management in adult patients in a high acuity medical surgical transitional care unit: a best practice implementation project. (United States)

    Sukhenko, Olga


    Excessive alcohol consumption, a major health problem worldwide, affects about 6% of the United States population. Caring for patients with alcohol withdrawal syndrome in a hospital ward presents complex physiologic and psycho-social challenges which are best met with evidence-based practices. An academic medical center in the United States has been experiencing an increase in patients with alcohol withdrawal syndrome. However, gaps in clinician knowledge and infrastructure supporting the management of these patients still existed. The aim of this project was to improve the continuity of care of patients undergoing alcohol withdrawal in a medical surgical high acuity transitional care unit by incorporating evidence-based practices, and thereby to positively impact on patient outcomes. Specific objectives were related to standardized assessments and pharmacologic management strategies. The project used the Joanna Briggs Institute's Practical Application of Clinical Evidence System and Getting Research into Practice audit tool for promoting change in health practice. A baseline clinical audit was conducted to assess compliance with best practices for managing alcohol withdrawal syndrome, which was followed by several interventions targeted at nurses and providers. A follow-up audit was conducted to assess compliance with the implemented strategies. The follow-up audit used the same evidence-based audit criteria as those used for the baseline audit. A non-probabilistic, convenience sampling approach was used. A sample size of 15 patients was used for both the baseline and follow-up audits. The baseline audit revealed a high compliance rate for four of the five audit criteria concerning risk assessment and pharmacologic strategies. There was sub-optimal compliance (53%) with the criterion regarding use of the Clinical Institute Withdrawal Assessment of Alcohol Scale (revised) (CIWA-Ar) scale to assess patients with alcohol withdrawal. After the interventions were

    Bonnet, Udo; Banger, Markus; Leweke, F Markus; Specka, Michael; Müller, Bernhard W; Hashemi, Thilo; Nyhuis, Peter W; Kutscher, Sven; Burtscheidt, Wilhelm; Gastpar, Markus


    A few case reports and data from animal experiments point to a possible efficacy of gabapentin (GP) in the treatment of alcohol withdrawal syndrome (AWS). Because of ethical considerations, the efficacy of GP in acute AWS was tested in an add-on fashion to clomethiazole (CLO). Given that the symptom-triggered amount of CLO required to limit AWS within the first 24 hours is related to the severity of AWS, we tested this amount of CLO during placebo (P) or GP (400 mg qid) under double blind, randomized conditions. Sixty-one patients (P = 29/GP = 32) suffering from alcohol dependence (ICD-10) and without any other psychiatric condition or psychotropic medication were included. The groups were not significantly different in baseline characteristics (eg, demographic data, severity of AWS). Both ITT and completer analyses revealed no significant differences between the groups considering the primary effectiveness measure: amount of CLO required in the first 24 hours (P = 6.1 +/- 5.4/GP = 6.2 +/- 4.7 capsules). In addition, premature discontinuations (P = 3/GP = 2) and decreases in Mainz Alcohol Withdrawal Scores were not significantly different in the first 48 hours of AWS (secondary effectiveness measures). Tolerability of combined CLO/GP was studied throughout the whole treatment comprising a 5-day lasting reduction part subsequent to the first 48 hours. Throughout the whole 7-day treatment a total of 5 and 2 patients dropped out and 6 and 5 patients reported adverse clinical events in the P and GP groups, respectively. All together, GP (400 mg qid) was no better than P in saving initial consumption of CLO or decreasing initial Mainz Alcohol Withdrawal Scores suggesting that GP was ineffective in the management of acute AWS in this model. The combination of GP and CLO was safe.

  19. Change in size, shape and radiocolloid uptake of the alcoholic liver during alcohol withdrawal, as demonstrated by single photon emission computed tomography

    International Nuclear Information System (INIS)

    Blomquist, L.; Yansen Wang; Jacobsson, H.; Kimiaei, S.


    The volume of the total liver and separate right and left lobes was studied before and after 1 week of alcohol withdrawal in 16 consecutive alcoholics by means of single photon emission computed tomography after intravenous injection of 99 Tc m -human albumin colloid; the relative tissue distribution of radioactivity was also followed. The left liver lobe increased in volume more than the right lobe during drinking and decreased more rapidly after alcohol withdrawal. Median volume reductions during 1 week of alcohol withdrawal were: total liver 12%, left lob 26%, and right lobe 8%, indicating that half of the reduction to values of a control group was achieved during this first week. The volume of the right but not of the left lobe was significantly correlated to body size in alcoholics and in controls. The left lobe had a lower capacity to concentrate the radiocolloid than the right lobe in alcoholics and in controls. The liver/spleen, liver/bone marrow and liver/background radioactivity concentration ratios in the alcoholics increased during alcohol withdrawal We conclude that heavy drinking causes both an increased total liver volume and a change in liver shape, with a relatively more enlarged left right lobe, as well as a decreased capacity to concentrate radiocolloid. These changes are rapidly reversible during abstinence from alcohol. (au) (26 refs.)

  1. Prognostic analysis of patients with epilepsy according to time of relapse after withdrawal of antiepileptic drugs following four seizure-free years. (United States)

    Park, Soochul; Lee, Dong Hyun; Kim, Seung Woo; Roh, Yun Ho


    We performed a retrospective, prognostic analysis of a cohort of patients with epilepsy according to time of relapse after four seizure-free years. Planned withdrawal of antiepileptic drugs (AEDs) and at least 3 years of follow-up after AED discontinuation were performed. The following two groups were assessed: (1) an early relapse (ER) group of patients who experienced recurrence during AED withdrawal and (2) a late relapse (LR) group of patients who experienced recurrence after completion of the AED discontinuation process. After dichotomization, the relapse rate, prognostic factors, and their impacts for each group were compared with those of a group of patients who continued to be seizure-free after AED withdrawal (SF group) using multiple logistic regression analysis. The AED intake mode was also analyzed. Two hundred seventeen (64.6%) of the 336 total patients experienced relapse. One hundred thirty-nine patients (41.4%) and 78 patients (23.2%) were included in the LR and ER groups, respectively. Symptom duration >120 months showed the strongest negative prognostic impact as demonstrated by the 4.7-fold higher risk of recurrence in the ER group compared with the SF group. Additional factors with a negative prognostic impact included an age at epilepsy onset of ≤20 years and the presence of localization-related epilepsy. No reliable predictor between the SF and LR groups was revealed. After exclusion of the SF group, post hoc analysis according to age at epilepsy onset and symptom duration showed that the above-mentioned negative prognostic factors significantly affected the relapse patterns of the LR and ER groups. The results suggest that longer symptom duration, which could be associated with intrinsic reactivation of epilepsy, is the strongest negative prognostic factor for relapse. Relapse after AED withdrawal in prolonged follow-up of seizure-free patients is one aspect of the natural history of epilepsy. © 2016 The Authors. Epilepsia published by

  2. Administration of memantine during withdrawal mitigates overactivity and spatial learning impairments associated with neonatal alcohol exposure in rats. (United States)

    Idrus, Nirelia M; McGough, Nancy N H; Riley, Edward P; Thomas, Jennifer D


    Prenatal alcohol exposure can disrupt central nervous system development, manifesting as behavioral deficits that include motor, emotional, and cognitive dysfunction. Both clinical and animal studies have reported binge drinking during development to be highly correlated with an increased risk of fetal alcohol spectrum disorders (FASD). We hypothesized that binge drinking may be especially damaging because it is associated with episodes of alcohol withdrawal. Specifically, we have been investigating the possibility that NMDA receptor-mediated excitotoxicity occurs during alcohol withdrawal and contributes to developmental alcohol-related neuropathology. Consistent with this hypothesis, administration of the NMDA receptor antagonists MK-801 or eliprodil during withdrawal attenuates behavioral alterations associated with early alcohol exposure. In this study, we investigated the effects of memantine, a clinically used NMDA receptor antagonist, on minimizing ethanol-induced overactivity and spatial learning deficits. Sprague-Dawley pups were exposed to 6.0 g/kg ethanol via intubation on postnatal day (PD) 6, a period of brain development that models late gestation in humans. Controls were intubated with a calorically matched maltose solution. During withdrawal, 24 and 36 hours after ethanol exposure, subjects were injected with a total of either 0, 20, or 30 mg/kg memantine. The subjects' locomotor levels were recorded in open field activity monitors on PDs 18 to 21 and on a serial spatial discrimination reversal learning task on PDs 40 to 43. Alcohol exposure induced overactivity and impaired performance in spatial learning. Memantine administration significantly attenuated the ethanol-associated behavioral alterations in a dose-dependent manner. Thus, memantine may be neuroprotective when administered during ethanol withdrawal. These data have important implications for the treatment of EtOH's neurotoxic effects and provide further support that ethanol withdrawal

    H.A. Lopez Morra


    Full Text Available Hepatosplenic gamma/delta T-cell lymphoma is a rare neoplasm of mature gamma/delta T-cells with sinusoidal infiltration of spleen, liver, and bone marrow. Patients are predominantly adolescent and young adult males and usually present with marked hepatosplenomegaly. Pancytopenia is another common finding. Despite an initial response to treatment, patients have a median survival of one to two years. In this report, we document a case of alcoholic hepatitis and methadone withdrawal masquerading unsuspected, hepatosplenic gamma/delta T-cell lymphoma with unusual CD20 positivity.

  5. Involvement of delta opioid receptors in alcohol withdrawal-induced mechanical allodynia in male C57BL/6 mice. (United States)

    Alongkronrusmee, Doungkamol; Chiang, Terrance; van Rijn, Richard M


    As a legal drug, alcohol is commonly abused and it is estimated that 17 million adults in the United States suffer from alcohol use disorder. Heavy alcoholics can experience withdrawal symptoms including anxiety and mechanical allodynia that can facilitate relapse. The molecular mechanisms underlying this phenomenon are not well understood, which stifles development of new therapeutics. Here we investigate whether delta opioid receptors (DORs) play an active role in alcohol withdrawal-induced mechanical allodynia (AWiMA) and if DOR agonists may provide analgesic relief from AWiMA. To study AWiMA, adult male wild-type and DOR knockout C57BL/6 mice were exposed to alcohol by a voluntary drinking model or oral gavage exposure model, which we developed and validated here. We also used the DOR-selective agonist TAN-67 and antagonist naltrindole to examine the involvement of DORs in AWiMA, which was measured using a von Frey model of mechanical allodynia. We created a robust model of alcohol withdrawal-induced anxiety and mechanical allodynia by orally gavaging mice with 3g/kg alcohol for three weeks. AWiMA was exacerbated and prolonged in DOR knockout mice as well as by pharmacological blockade of DORs compared to control mice. However, analgesia induced by TAN-67 was attenuated during withdrawal in alcohol-gavaged mice. DORs appear to play a protective role in the establishment of AWiMA. Our current results indicate that DORs could be targeted to prevent or reduce the development of AWiMA during alcohol use; however, DORs may be a less suitable target to treat AWiMA during active withdrawal.

  6. Comparison of Alcohol Withdrawal Outcomes in Patients Treated with Benzodiazepines Alone versus Adjunctive Phenobarbital: a Retrospective Cohort Study

    Directory of Open Access Journals (Sweden)

    Lauren Z. Gashlin


    Full Text Available Background: For treatment of severe alcohol withdrawal syndrome, high dose benzodiazepines (BZDs may cause delirium and over-sedation. Phenobarbital (PBT is a long-acting barbiturate effective for the treatment of alcohol withdrawal. Given the potential benefits of PBT, we sought to investigate the effectiveness of PBT as adjunctive treatment for alcohol withdrawal. Methods: This was a retrospective cohort study on patients with a diagnosis of alcohol withdrawal who had a CIWA-Ar score > 10 treated with either BZDs alone (BZD alone group or BZDs with adjunctive PBT (PBT-adjunct group. The patients received at least one dose of PBT in addition to BZDs (variable doses in the PBT-adjunct group, and three doses of 20 mg diazepam equivalents within 6 hours in the BZD alone group. The primary endpoint was the proportion of patients with a CIWA-Ar score < 10 at 24 hours after initial treatment. Duration of withdrawal and cumulative dose of BZDs were also assessed. Results: Seven subjects in the adjunctive phenobarbital and 21 in the benzodiazepine group were included in the final analysis. Two patients (28.6% in the PBT-adjunct group and 5 patients (23.8% in the BZD only group achieved the primary endpoint, though the difference between the two groups was not statistically significant (P = 0.588. The median (IQR duration of withdrawal symptoms was 44 (12-62 hours in the PBT-adjunct group compared to 53 (37-87 hours in the BZD only group, with no significant difference between the groups (P = 0.249. The median (IQR cumulative BZD dose requirement (diazepam equivalent in the PBT-adjunct group was significantly lower than BZD alone group (25 (20-226 vs. 326 (160-550 mg, P = 0.02. Conclusion: PBT appears to be a safe and effective alternative to BZDs for the treatment of alcohol withdrawal in non-critically ill patients and may be BZD sparing.

  7. Trends in pharmacotherapy selection for the treatment of alcohol withdrawal in the Free State Province, South Africa

    Directory of Open Access Journals (Sweden)

    Paulina M van Zyl


    Objectives. To engage with the problem of translating research into practice, as reflected by the selection of pharmacotherapy for alcohol withdrawal by medical practitioners in the Free State Province, South Africa. Methods. A questionnaire-based survey and interviews were conducted among 121 professionals in both the private and public sectors across the province. A subgroup was formed comprising the 58 doctors who indicated that they prescribe for alcohol withdrawal. Participants worked in private general practice, specialist psychiatry practice, in a state hospital or in a treatment centre. Results. Prescribing practices varied based on practitioners’ geographical distribution and professional capacity. Deviation from standard recommendations included the routine use of clothiapine and antidepressants in withdrawal regimens. Prescribing clothiapine appears to be a local custom. While prescription of antidepressants may indicate unrealistic expectations of therapeutic benefit, there are clear indications that this is maintained to mask the diagnosis of an alcohol-related condition. Prescribing for alcohol withdrawal is therefore not necessarily determined by pathophysiology or efficacy of medication. Conclusion. Withdrawal regimens need to be reassessed by researchers, policy makers and funders, balancing new developments with the real-life experiences and challenges of prescribers and their patients.

  8. [Mental and physical symptoms in alcoholics after alcohol withdrawal--comparing with involutional melancholia patients]. (United States)

    Kobayashi, T; Hayakawa, S; Matsuda, M; Tsuchida, H; Haga, H; Tani, N; Fukui, K


    As a factor of recurrence of drinking in patients with alcoholic dependence, emotional disorders accompanied by alcohol dependence has been noted in many reports. Particularly, it is noted to be very likely that depression after abstinence is an incentive to re-start drinking. In this study, we investigated depressive feeling in aspects of psychiatric and physical subjective symptoms after abstinence in patients with alcohol dependence, and compared the symptoms with those in patients with involutional depression. On analysis of the major component of psychiatric subjective symptoms, a sense of alienation, emotional instability, anxiety, and aggressiveness were observed. In involutional depression, depressive feeling, somnipathy, anxiety, self accusation/sense of guilt, delusion of culpability were observed. On analysis of the major component of physical subjective symptoms, autonomic nervous symptoms accompanied by feebleness, hysterical neurosis-like autonomic nervous symptoms, reduced sexual libido, anorexia, hydrodipsia/sweating were observed. Similarly, in patients with involutional depression, hysterical neurosis-like autonomic nervous symptoms, anorexia, elevation of tonus, general malaise, and hydrodipsia were noted. Differences in status were emphasized in comparison between the two groups in both analyses. Unlike involutional depression that exhibits the current features of depression, patients with alcohol dependence showed a sense of alienation, emotional instability, anxiety, and aggressiveness, reflecting self-uncertainty and loss of self-respect. Drinking may be re-started to relieve or reduce tension and frustration in such conditions.

  9. Pharmacological activation/inhibition of the cannabinoid system affects alcohol withdrawal-induced neuronal hypersensitivity to excitotoxic insults.

    Directory of Open Access Journals (Sweden)

    Marina Rubio

    Full Text Available Cessation of chronic ethanol consumption can increase the sensitivity of the brain to excitotoxic damages. Cannabinoids have been proposed as neuroprotectants in different models of neuronal injury, but their effect have never been investigated in a context of excitotoxicity after alcohol cessation. Here we examined the effects of the pharmacological activation/inhibition of the endocannabinoid system in an in vitro model of chronic ethanol exposure and withdrawal followed by an excitotoxic challenge. Ethanol withdrawal increased N-methyl-D-aspartate (NMDA-evoked neuronal death, probably by altering the ratio between GluN2A and GluN2B NMDA receptor subunits. The stimulation of the endocannabinoid system with the cannabinoid agonist HU-210 decreased NMDA-induced neuronal death exclusively in ethanol-withdrawn neurons. This neuroprotection could be explained by a decrease in NMDA-stimulated calcium influx after the administration of HU-210, found exclusively in ethanol-withdrawn neurons. By contrast, the inhibition of the cannabinoid system with the CB1 receptor antagonist rimonabant (SR141716 during ethanol withdrawal increased death of ethanol-withdrawn neurons without any modification of NMDA-stimulated calcium influx. Moreover, chronic administration of rimonabant increased NMDA-stimulated toxicity not only in withdrawn neurons, but also in control neurons. In summary, we show for the first time that the stimulation of the endocannabinoid system is protective against the hyperexcitability developed during alcohol withdrawal. By contrast, the blockade of the endocannabinoid system is highly counterproductive during alcohol withdrawal.

    Majewska, Magdalena; Tchórz, Michał; Szponar, Jarosław; Radoniewicz-Chagowska, Anna; Kołodziej, Małgorzata


    Rhabdomyolysis and associated kidney failure is a medical problem, often faced by doctors working in the centers of toxicology. Its most common cause is mechanical damage to the muscles, but predisposing factors include a big group of other pathologies and clinical conditions, including: electrolyte imbalance, immobility, infections, drug or psychoactive substances poisoning. The article presents an example of a patient with severe rhabdomyolysis syndrome caused by an alcohol withdrawal syndrome. Based on our experience and scientific studies of other clinical centres the paper presents various causes of muscle damage, including the iatrogenic effects of ethanol intoxication treatment. The article explains the importance of a proper and quick treatment which prevents damage of internal organs, including kidney failure.

  11. Chronic alcohol consumption leads to neurochemical changes in the nucleus accumbens that are not fully reversed by withdrawal. (United States)

    Pereira, Pedro A; Neves, João; Vilela, Manuel; Sousa, Sérgio; Cruz, Catarina; Madeira, M Dulce


    Neuropeptide Y (NPY)- and acetylcholine-containing interneurons of the nucleus accumbens (NAc) seem to play a major role in the rewarding effects of alcohol. This study investigated the relationship between chronic alcohol consumption and subsequent withdrawal and the expression of NPY and acetylcholine in the NAc, and the possible involvement of nerve growth factor (NGF) in mediating the effects of ethanol. Rats ingesting an aqueous ethanol solution over 6months and rats subsequently deprived from ethanol during 2months were used to estimate the total number and the somatic volume of NPY and cholinergic interneurons, and the numerical density of cholinergic varicosities in the NAc. The tissue content of choline acetyltransferase (ChAT) and catecholamines were also determined. The number of NPY interneurons increased during alcohol ingestion and returned to control values after withdrawal. Conversely, the number and the size of cholinergic interneurons, and the amount of ChAT were unchanged in ethanol-treated and withdrawn rats, but the density of cholinergic varicosities was reduced by 50% during alcohol consumption and by 64% after withdrawal. The concentrations of dopamine and norepinephrine were unchanged both during alcohol consumption and after withdrawal. The administration of NGF to withdrawn rats significantly increased the number of NPY-immunoreactive neurons, the size of cholinergic neurons and the density of cholinergic varicosities. Present data show that chronic alcohol consumption leads to long-lasting neuroadaptive changes of the cholinergic innervation of the NAc and suggest that the cholinergic system is a potential target for the development of therapeutic strategies in alcoholism and abstinence.

  14. Voluntary co-consumption of alcohol and nicotine: Effects of abstinence, intermittency, and withdrawal in mice. (United States)

    O'Rourke, Kyu Y; Touchette, Jillienne C; Hartell, Elizabeth C; Bade, Elizabeth J; Lee, Anna M


    Alcohol and nicotine are often used together, and there is a high rate of co-occurrence between alcohol and nicotine addiction. Most animal models studying alcohol and nicotine interactions have utilized passive drug administration, which may not be relevant to human co-addiction. In addition, the interactions between alcohol and nicotine in female animals have been understudied, as most studies have used male animals. To address these issues, we developed models of alcohol and nicotine co-consumption in male and female mice that utilized voluntary, oral consumption of unsweetened alcohol, nicotine and water. We first examined drug consumption and preference in single-drug, sequential alcohol and nicotine consumption tests in male and female C57BL/6 and DBA/2J mice. We then tested chronic continuous and intermittent access alcohol and nicotine co-consumption procedures. We found that male and female C57BL/6 mice readily co-consumed unsweetened alcohol and nicotine. In our continuous co-consumption procedures, we found that varying the available nicotine concentration during an alcohol abstinence period affected compensatory nicotine consumption during alcohol abstinence, and affected rebound alcohol consumption when alcohol was re-introduced. Consumption of alcohol and nicotine in an intermittent co-consumption procedure produced higher alcohol consumption levels, but not nicotine consumption levels, compared with the continuous co-consumption procedures. Finally, we found that intermittent alcohol and nicotine co-consumption resulted in physical dependence. Our data show that these voluntary co-consumption procedures can be easily performed in mice and can be used to study behavioral interactions between alcohol and nicotine consumption, which may better model human alcohol and nicotine co-addiction.

  16. Effects of chronic alcohol consumption, withdrawal and nerve growth factor on neuropeptide Y expression and cholinergic innervation of the rat dentate hilus. (United States)

    Pereira, Pedro A; Rocha, João P; Cardoso, Armando; Vilela, Manuel; Sousa, Sérgio; Madeira, M Dulce


    Several studies have demonstrated the vulnerability of the hippocampal formation (HF) to chronic alcohol consumption and withdrawal. Among the brain systems that appear to be particularly vulnerable to the effects of these conditions are the neuropeptide Y (NPY)-ergic and the cholinergic systems. Because these two systems seem to closely interact in the HF, we sought to study the effects of chronic alcohol consumption (6months) and subsequent withdrawal (2months) on the expression of NPY and on the cholinergic innervation of the rat dentate hilus. As such, we have estimated the areal density and the somatic volume of NPY-immunoreactive neurons, and the density of the cholinergic varicosities. In addition, because alcohol consumption and withdrawal are associated with impaired nerve growth factor (NGF) trophic support and the administration of exogenous NGF alters the effects of those conditions on various cholinergic markers, we have also estimated the same morphological parameters in withdrawn rats infused intracerebroventricularly with NGF. NPY expression increased after withdrawal and returned to control values after NGF treatment. Conversely, the somatic volume of these neurons did not differ among all groups. On other hand, the expression of vesicular acetylcholine transporter (VAChT) was reduced by 24% in ethanol-treated rats and by 46% in withdrawn rats. The administration of NGF to withdrawn rats increased the VAChT expression to values above control levels. These results show that the effects of prolonged alcohol intake and protracted withdrawal on the hilar NPY expression differ from those induced by shorter exposures to ethanol and by abrupt withdrawal. They also suggest that the normalizing effect of NGF on NPY expression might rely on the NGF-induced improvement of cholinergic neurotransmission in the dentate hilus. Copyright © 2016 Elsevier Inc.

  17. A systematic nurse-led approach to withdrawal risk screening, prevention and treatment among inpatients with an alcohol use disorder in an ear, nose, throat and jaw surgery department-A formative evaluation. (United States)

    Leuenberger, Deborah Linda; Fierz, Katharina; Hinck, Andreas; Bodmer, Daniel; Hasemann, Wolfgang


    Among patients with head and neck cancer comorbid alcohol use disorder is frequent which contributes to higher risk of developing perioperative alcohol withdrawal syndrome/delirium or delirium due to medical conditions. Although guidelines emphasize prevention and treatment of alcohol withdrawal in hospitalized patients, a validated systematic approach for management of these patients is still lacking. Our aim was to formatively evaluate our newly developed systematic approach in view of nurses' adherence to screening patients for regular alcohol consumption and managing their withdrawal symptoms using the Clinical Institute Withdrawal Assessment of Alcohol Scale, Revised. We conducted a formative evaluation to improve the project's design and performance and used a retrospective chart review in a consecutive sample of all adult inpatients with head and neck cancer being assigned for surgery in a university hospital. Our bundle of interventions consisted of nurses' screenings for regular alcohol consumption, withdrawal risk assessment, offering patients a substitution therapy, nurses' assessments of withdrawal symptoms and symptom oriented withdrawal management. Proximate endpoints were analyzed descriptively at each component of the bundle in terms of frequencies and severity of withdrawal symptoms, frequencies of nurses' and doctors' screenings and nurses' assessments performed as required. Between 2013 and 2014, 87 inpatients met inclusion criteria and screenings by doctors/ nurses revealed 49 alcohol consumers, where six screenings were omitted by nurses and six by doctors. Twenty-one consumers were at risk and six of them developed an alcohol withdrawal syndrome. None of the 87 showed an alcohol withdrawal delirium, but five developed a delirium due to medical conditions. Nurses correctly conducted all preventive elements of the intervention bundle in 14 (58%) patients at risk but overall, only performed 50% of the required assessments. Although nurses safely

  19. Serotonergic anti-depressants and ethanol withdrawal syndrome: a review. (United States)

    Uzbay, I Tayfun


    To review laboratory findings on the effects of anti-depressant agents that interact with the serotonergic system on signs of ethanol withdrawal syndrome in rats. Adult Wistar rats received a modified liquid diet to produce ethanol dependence. Signs of ethanol withdrawal, locomotor hyperactivity, stereotyped behaviour, tremor, wet dog shakes, agitation, and audiogenic seizures, were evaluated for the first 6 h of ethanol withdrawal. The effects of the anti-depressants fluoxetine, venlafaxine, escitalopram, tianeptine, and extract of Hypericum perforatum (St. John's wort) (HPE) were examined. Some beneficial effects of fluoxetine, tianeptine, HPE, escitalopram and venlafaxine on ethanol withdrawal signs were observed, ranked as follows: fluoxetine = tianeptine > HPE > escitalopram > venlafaxine. Tianeptine and fluoxetine seem to be potent pharmacologically active agents on ethanol withdrawal syndrome in rats. Thus, these anti-depressants may be useful in treatment of ethanol withdrawal syndrome in patients with alcoholism. In addition to serotonergic effects, interactions with nitrergic, glutamatergic, and adenosinergic systems may also provide a significant contribution to the beneficial effects of these drugs on ethanol withdrawal syndrome.

    Full Text Available Abstract Background Monitoring the scale of pharmaceuticals, illicit and licit drugs consumption is important to assess the needs of law enforcement and public health, and provides more information about the different trends within different countries. Community drug use patterns are usually described by national surveys, sales and seizure data. Wastewater-based epidemiology (WBE has been shown to be a reliable approach complementing such surveys. Method This study aims to compare and correlate the consumption estimates of pharmaceuticals, illicit drugs, alcohol, nicotine and caffeine from wastewater analysis and other sources of information. Wastewater samples were collected in 2015 from 8 different European cities over a one week period, representing a population of approximately 5 million people. Published pharmaceutical sale, illicit drug seizure and alcohol, tobacco and caffeine use data were used for the comparison. Results High agreement was found between wastewater and other data sources for pharmaceuticals and cocaine, whereas amphetamines, alcohol and caffeine showed a moderate correlation. methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA and nicotine did not correlate with other sources of data. Most of the poor correlations were explained as part of the uncertainties related with the use estimates and were improved with other complementary sources of data. Conclusions This work confirms the promising future of WBE as a complementary approach to obtain a more accurate picture of substance use situation within different communities. Our findings suggest further improvements to reduce the uncertainties associated with both sources of information in order to make the data more comparable.

  2. Adolescent Mice Are Resilient to Alcohol Withdrawal-Induced Anxiety and Changes in Indices of Glutamate Function within the Nucleus Accumbens. (United States)

    Lee, Kaziya M; Coelho, Michal A; McGregor, Hadley A; Solton, Noah R; Cohen, Matan; Szumlinski, Karen K


    Binge-drinking is the most prevalent form of alcohol abuse and while an early life history of binge-drinking is a significant risk factor for subsequent alcoholism and co-morbid affective disorders, relatively little is known regarding the biobehavioral impact of binge-drinking during the sensitive neurodevelopmental period of adolescence. In adult mice, a month-long history of binge-drinking elicits a hyper-glutamatergic state within the nucleus accumbens (Acb), coinciding with hyper-anxiety. Herein, we employed a murine model of binge-drinking to determine whether or not: (1) withdrawal-induced changes in brain and behavior differ between adult and adolescent bingers; and (2) increased behavioral signs of negative affect and changes in Acb expression of glutamate-related proteins would be apparent in adult mice with less chronic binge-drinking experience (14 days, approximating the duration of mouse adolescence). Adult and adolescent male C57BL/6J mice were subjected to a 14-day binge-drinking protocol (5, 10, 20 and 40% alcohol (v/v) for 2 h/day), while age-matched controls received water. At 24 h withdrawal, half of the animals from each group were assayed for negative affect, while tissue was sampled from the shell (AcbSh) and core (AcbC) subregions of the remaining mice for immunoblotting analyses. Adult bingers exhibited hyper-anxiety when tested for defensive marble burying. Additionally, adult bingers showed increased mGlu1, mGlu5, and GluN2b expression in the AcbSh and PKCε and CAMKII in the AcbC. Compared to adults, adolescent mice exhibited higher alcohol intake and blood alcohol concentrations (BACs); however, adolescent bingers did not show increased anxiety in the marble-burying test. Furthermore, adolescent bingers also failed to exhibit the same alcohol-induced changes in mGlu and kinase protein expression seen in the adult bingers. Irrespective of age, bingers exhibited behavioral hyperactivity in the forced swim test (FST) compared to water

  3. Identification of a QTL in Mus musculus for alcohol preference, withdrawal, and Ap3m2 expression using integrative functional genomics and precision genetics. (United States)

    Bubier, Jason A; Jay, Jeremy J; Baker, Christopher L; Bergeson, Susan E; Ohno, Hiroshi; Metten, Pamela; Crabbe, John C; Chesler, Elissa J


    Extensive genetic and genomic studies of the relationship between alcohol drinking preference and withdrawal severity have been performed using animal models. Data from multiple such publications and public data resources have been incorporated in the GeneWeaver database with >60,000 gene sets including 285 alcohol withdrawal and preference-related gene sets. Among these are evidence for positional candidates regulating these behaviors in overlapping quantitative trait loci (QTL) mapped in distinct mouse populations. Combinatorial integration of functional genomics experimental results revealed a single QTL positional candidate gene in one of the loci common to both preference and withdrawal. Functional validation studies in Ap3m2 knockout mice confirmed these relationships. Genetic validation involves confirming the existence of segregating polymorphisms that could account for the phenotypic effect. By exploiting recent advances in mouse genotyping, sequence, epigenetics, and phylogeny resources, we confirmed that Ap3m2 resides in an appropriately segregating genomic region. We have demonstrated genetic and alcohol-induced regulation of Ap3m2 expression. Although sequence analysis revealed no polymorphisms in the Ap3m2-coding region that could account for all phenotypic differences, there are several upstream SNPs that could. We have identified one of these to be an H3K4me3 site that exhibits strain differences in methylation. Thus, by making cross-species functional genomics readily computable we identified a common QTL candidate for two related bio-behavioral processes via functional evidence and demonstrate sufficiency of the genetic locus as a source of variation underlying two traits.

  4. Heavy Alcohol Consumption Effects on Blood Pressure and on Kidney Structure Persist After Long-Term Withdrawal

    Directory of Open Access Journals (Sweden)

    Sandra Leal


    Full Text Available Background/Aims: Heavy ethanol consumption is a risk factor for hypertension and prompts organ damage. There is no information regarding the impact of long-term heavy ethanol consumption on kidney structure and function linking to their hypertensive effects nor the repercussions after withdrawal. Methods: Rats were exposed to ethanol for 24 weeks and, afterwards, a group was assigned to withdrawal for 8 weeks. Blood pressure (BP was measured and serum biochemical parameters were quantified. Glomerular volume density, areal density of glomerular tuft and renal corpuscles were determined. Angiotensin II type 1 receptor (AT1R protein expression was evaluated. Results: Twenty-four weeks of ethanol consumption causes atrophy of renal corpuscles and glomeruli and reduces the volume of glomeruli. Glomerular changes induced by ethanol consumption were still evident after withdrawal. Renal AT1R levels were increased in ethanol-treated rats and returned to control levels during withdrawal. Ethanol consumption also induced an increase in BP, uric acid and albumin levels. Upon withdrawal, systolic and mean arterial pressures decreased, but were still higher than in controls rats. Conclusion: Ethanol consumption induces changes in glomerular morphology associated with increased BP and AT1R expression. Long-term withdrawal was inefficient to restore the structural integrity of renal corpuscles and in lowering systolic pressure.

  5. Acute illness-induced behavioral alterations are similar to those observed during withdrawal from acute alcohol exposure (United States)

    Richey, Laura; Doremus-Fitzwater, Tamara L.; Buck, Hollin M.; Deak, Terrence


    Exposure to an immunogen results in a constellation of behavioral changes collectively referred to as “sickness behaviors,” with alterations in cytokine expression previously shown to contribute to this sickness response. Since behaviors observed during ethanol withdrawal are strikingly similar to sickness behaviors, we hypothesized that behavioral manifestations of ethanol withdrawal might be an expression of sickness behaviors induced by ethanol-related changes in peripheral and/or central cytokine expression. Accordingly, behaviors exhibited during a modified social investigation test were first characterized in male rats following an acute injection of lipopolysaccharide (LPS; 100 μg/kg). Subsequently, behavioral changes after either a high (4-g/kg; Experiment 2) or low dose (0.5 g/kg; Experiment 3) of ethanol were also examined in the same social investigation test, as well as in the forced-swim test (FST; Experiment 4). Results from these experiments demonstrated similar reductions in both exploration and social investigatory behavior during acute illness and ethanol withdrawal, while a seemingly paradoxical decrease in immobility was observed in the FST during acute ethanol withdrawal. In follow-up studies, neither indomethacin (Experiment 5) nor interleukin-1 receptor antagonist (Experiment 6) pre-exposure reversed the ethanol withdrawal-induced behavioral changes observed in this social investigation test. Taken together, these studies demonstrate that the behavioral sequelae of acute illness and ethanol withdrawal are similar in nature, while antagonist studies suggest that these behavioral alterations are not reversed by blockade of IL-1 receptors or inhibition of prostaglandin synthesis. Though a direct mechanistic link between cytokines and the expression of acute ethanol withdrawal-related behaviors has yet to be found, future studies examining the involvement of brain cytokines as potential mediators of ethanol effects are greatly needed.

  6. [Psychotic experiences in the course of alcohol withdrawal symptoms: locus of control among patients with and without delirium and analysis of subjective experiences in delirium]. (United States)

    Kokoszka, Andrzej; Laskowska, Marta; Mikuła, Joanna


    The comparison of the locus of control in groups of patients hospitalised due to alcohol withdrawal with and without delirium and analysis of psychotic experiences of patients with delirium. 25 patients with alcohol withdrawal with delirium and 25 without delirium took part in the study. They filled-in the Internal-External (I-E) Locus of Control Scale by Rotter; Multidimensional Health Locus of Control (MHLC) scale; the group with delirium also did the Psychopathological Symptoms Inventory, by Bizoń et al. The mean score in I-E Locus of Control Scale in the group with delirium was more external than in the group without delirium (M = 13.28; SD = 2.762 versus M = 11.64; SD = 2.612; t(48) = -2.157; p = 0.036). Group with delirium had also lower mean score in the dimension of internal control in MHLC, than the group without delirium (M = 24.8; SD = 6.149 versus M = 26.8; SD = 4.648; t(48) = 1.99; p = 0.04). There were no statistically significant differences between the groups in the other subscales. The auditory and visual hallucinations were most common among patients with delirium (84%, 80% respectively, as well as delusions of taking part in not existing events (92%) and persecutory delusions (80%). Psychotic experiences influenced behaviour in nearly 50% of the cases. A more external locus of control may be one of the factors contributing to the development of alcohol delirium. The content of psychotic experiences seems to have impact on the behaviour of many patients with alcohol delirium.

  7. Role of CYP2C19 gene polymorphism in acute alcohol withdrawal treatment with loading dose of diazepam in a South Indian population. (United States)

    Jose, Manu; Mathaiyan, Jayanthi; Kattimani, Shivanand; Adithan, Surendiran; Chandrasekaran, Adithan


    Alcohol dependence is a public health problem worldwide, commonly associated with withdrawal symptoms for which diazepam is a frequently used drug. We studied the effect of CYP2C19 gene polymorphisms on diazepam loading dose requirement and time to reversal of acute alcohol withdrawal symptoms. We also studied the influence of the polymorphism in this gene on the persistent symptoms after loading dose of diazepam. Sixty-nine patients who reported to the psychiatry department with symptoms of alcohol withdrawal diagnosed by DSM-IV criteria were included for the study. A 10-mg loading dose of diazepam was administered iv after baseline assessment of withdrawal severity using CIWA-Ar scoring. The patients were assessed for improvement of the symptoms every two hourly and 20 mg oral diazepam was given based on improvement of symptoms. Genotyping for CYP2C19*2, CYP2C19*3 and CYP2C19*17 was done by PCR-RFLP and RT-PCR methods. The diazepam dose requirement as well as the time required for reversal of acute symptoms was not statistically different among the different genotype groups. Similarly, the frequency of patients with persistent symptoms after successful treatment of the acute episode was not different among the groups. However, the total diazepam dose requirement was influenced by baseline CIWA-Ar scores (adjusted OR 0.21, p = 0.026). In addition, the odds of treatment with a lower dose (10 mg) of diazepam were higher in smokers (adjusted OR 5.22, p = 0.025) and patients with other addiction (adjusted OR 9.26, p = 0.026). We found that CYP2C19 polymorphism did not have any significant effect on the diazepam dose requirement, time duration needed for successful treatment or on the persistent symptoms after loading dose of diazepam in South Indian population. However, diazepam dose requirement was influenced by baseline CIWA-Ar score, smoking status and other comorbid addictions.

  8. Alcohol consumption increases locomotion in an open field and induces Fos-immunoreactivity in reward and approach/withdrawal-related neurocircuitries. (United States)

    Wscieklica, Tatiana; de Barros Viana, Milena; Le Sueur Maluf, Luciana; Pouza, Kathlein Cristiny Peres; Spadari, Regina Célia; Céspedes, Isabel Cristina


    Drug addiction is a chronically relapsing disorder characterized by compulsion to seek and take the drug, loss of control in limiting intake and, eventually, the emergence of a negative emotional state when access to the drug is prevented. Both dopamine and corticotropin-releasing factor (CRF)-mediated systems seem to play important roles in the modulation of alcohol abuse and dependence. The present study investigated the effects of alcohol consumption on anxiety and locomotor parameters and on the activation of dopamine and CRF-innervated brain regions. Male Wistar rats were given a choice of two bottles for 31 days, one containing water and the other a solution of saccharin + alcohol. Control animals only received water and a solution of 0.2% saccharin. On the 31st day, animals were tested in the elevated plus-maze and open field, and euthanized immediately after the behavioral tests. An independent group of animals was treated with ethanol and used to measure blood ethanol concentration. Results showed that alcohol intake did not alter behavioral measurements in the plus-maze, but increased the number of crossings in the open field, an index of locomotor activity. Additionally, alcohol intake increased Fos-immunoreactivity (Fos-ir) in the prefrontal cortex, in the shell region of the nucleus accumbens, in the medial and central amygdala, in the bed nucleus of the stria terminalis, in the septal region, and in the paraventricular and dorsomedial hypothalamus, structures that have been linked to reward and to approach/withdrawal behavior. These observations might be relevant to a better understanding of the behavioral and physiological alterations that follow alcohol consumption. Copyright © 2016 Elsevier Inc. All rights reserved.

  9. The psychiatric management of patients with alcohol dependence. (United States)

    Ritvo, Jonathan I; Park, Charles


    Alcohol dependence is a chronic, relapsing biobehavioral disease mediated by various parts of the brain, including reward systems, memory circuits, and the prefrontal cortex. It is characterized by loss of the ability to drink alcohol in moderation and continued drinking despite negative consequences. The alcohol withdrawal syndrome is a common but not universal diagnostic feature of alcohol dependence. Benzodiazepine detoxification of the alcohol withdrawal syndrome prevents the development of withdrawal seizures and delirium tremens, and makes patients more comfortable, which promotes engagement in treatment. Symptom-triggered dosing, based on a withdrawal rating scale such as the Clinical Institute Withdrawal Assessment of Alcohol Scale, Revised, is optimal for minimizing the total benzodiazepine dosage. Use of a long-acting benzodiazepine (eg, chlordiazepoxide) is preferred in uncomplicated patients. Thiamine should be administered routinely before the administration of intravenous fluids to prevent the development of Wernicke's encephalopathy and Wernicke-Korsakoff syndrome. In combination with psychosocial treatment, disulfiram, naltrexone, and acamprosate can reduce the frequency of relapse. Naltrexone may be more effective for reduction of loss of control with the first drink and cue-related craving, and acamprosate may be more effective for stabilizing the physiology of post-acute withdrawal. Disulfiram, an aversive deterrent, can be useful if administration can be monitored and tied to meaningful contingencies or when used prophylactically for situations anticipated to carry high risk of relapse. Psychiatric comorbidity, especially depression, is common and is best addressed concurrently, although definitive diagnosis may have to await a period of prolonged sobriety. Prescription of addictive substances, including benzodiazepines beyond the period of acute detoxification, should be avoided, and if necessary should be closely monitored (eg, by frequent

  11. Flumazenil and seizures: analysis of 43 cases. (United States)

    Spivey, W H


    Flumazenil is a new drug indicated for the reversal of the sedative effects of benzodiazepines mediated at the benzodiazepine-receptor site. Worldwide sources to date have disclosed 43 cases of seizures related, at least temporally, to the intravenous administration of flumazenil. There was no apparent relationship between the dose of flumazenil and the development of seizures, which occurred at doses ranging from 0.2 to 10.0 mg. The seizures were not considered to be a toxic effect of flumazenil, but many of them probably were due to an unmasking of the anticonvulsant effect of the previously used benzodiazepine or to a severe benzodiazepine-withdrawal syndrome. Eighteen (42%) of the patients had ingested overdoses of cyclic antidepressants, which were considered responsible for the seizures. In addition to patients with concurrent cyclic antidepressant poisoning, high-risk populations include patients who have been treated with benzodiazepines for a seizure disorder or an acute convulsive episode, patients with concurrent major sedative-hypnotic drug withdrawal, patients who have recently been treated with repeated doses of parenteral benzodiazepines, and overdose patients with myoclonic jerking or seizure activity before flumazenil administration. To minimize the likelihood of a seizure, it is recommended that flumazenil not be administered to patients who have used benzodiazepines for the treatment of seizure disorders or to patients who have ingested drugs (eg, cyclic antidepressants, cocaine, lithium, methylxanthines, isoniazid, propoxyphene, monoamine oxidase inhibitors, buproprion HCl, and cyclosporine) that place them at risk for the development of seizures.

  12. A randomized, open-label, standard controlled, parallel group study of efficacy and safety of baclofen, and chlordiazepoxide in uncomplicated alcohol withdrawal syndrome. (United States)

    Girish, K; Vikram Reddy, K; Pandit, Lakshmi V; Pundarikaksha, H P; Vijendra, R; Vasundara, K; Manjunatha, R; Nagraj, Moulya; Shruthi, R


    Alcohol withdrawal syndrome (AWS) is a distressing condition, generally controlled by benzodiazepines (BZD's). Baclofen, a gamma-aminobutyric acid-B (GABAB) agonist, has also shown promising results in controlling AWS. As there are few studies comparing the efficacy and tolerability of chlordiazepoxide with baclofen, the present study was taken up. The objective of this study was to compare efficacy and tolerability of baclofen with chlordiazepoxide in uncomplicated AWS. Sixty subjects with uncomplicated AWS were randomized into two groups of 30 each, to receive baclofen (30 mg) or chlordiazepoxide (75 mg) in decremented fixed dose regime for 9 days. Clinical efficacy was assessed by Clinical Institute Withdrawal Assessment for Alcohol-Revised Scale (CIWA-Ar) and tolerability by the nature and severity of adverse events. Lorazepam was used as rescue medication. Secondary efficacy parameters were Clinical Global Impression scores, symptom-free days, and subject satisfaction as assessed by visual analog scale. This study was registered with Clinical Trial Registry-India (CTRI/2013/04/003588), also subsequently registered with WHO's ICTRP clinical trial portal. Both baclofen and chlordiazepoxide showed a consistent reduction in the total CIWA-Ar scores. However, chlordiazepoxide showed a faster and a more effective control of anxiety and agitation requiring lesser lorazepam supplementation, and also showed a better subject satisfaction compared to baclofen. Both the drugs showed good tolerability with mild self-limiting adverse events. The present study demonstrates that baclofen is not as good as chlordiazepoxide in the treatment of uncomplicated AWS. However, baclofen might be considered as an alternative. Copyright © 2016 Chang Gung University. Published by Elsevier B.V. All rights reserved.

  6. Seizure semiology: value in identifying seizure origin. (United States)

    Jan, Mohammed M S; Girvin, John P


    The diagnosis of epilepsy depends upon a number of factors, particularly detailed and accurate seizure history, or semiology. Other diagnostic data, consisting of electroencephalography, video-monitoring of the seizures, and magnetic resonance imaging, are important in any comprehensive epilepsy program, particularly with respect to lateralizing and localizing the seizure focus, if such a focus exists, and with respect to determining the type of seizure or seizure syndrome. The aim of this review is to present a survey of important semiologic characteristics of various seizures that provide the historian with observations, which help to lateralize and localize epileptic zones. Clinical semiology is the starting point of understanding a seizure disorder and making the diagnosis of epilepsy. While it may not provide unequivocal evidence of localization of the epileptic focus, nevertheless it usually directs subsequent investigations, whose concordance is necessary for the ultimate localization.

    Full Text Available O objetivo deste artigo é o de revisar e descrever as principais alterações neurofarmacológicas causadas pela exposição crônica ao álcool, assim como os fenômenos ocorridos durante o período de abstinência. São apresentados dados referentes às alterações neuroadaptativas e de tolerância ocorridas nos principais sistemas de monoaminas, aminoácidos neurotransmissores e canais de cálcio, o que está relacionado a uma piora no prognóstico de portadores de comorbidades psiquiátricas com o consumo de álcool. São também descritos alguns estudos relevantes que demonstram o envolvimento de outros mecanismos de ação do álcool no sistema nervoso central, como o envolvimento de opióides, entre outras substâncias. O artigo reafirma a importância, para clínicos e pesquisadores, de um sempre maior entendimento do mecanismo de ação central do álcool, pois dele depende a busca por novas opções farmacológicas, tanto para a redução dos danos provocados pelo seu uso crônico, como para o tratamento da síndrome de abstinência a esta substância.The objective of this paper is to review and describe the main neuropharmacological changes caused by the chronic use of alcohol and those observed during its withdrawal period. The results show international data referring to the involvement of monoamine systems, neurotransmitters and calcium channels in both neuroadaptation and tolerance to alcohol effects and withdrawal. Relevant studies showing the participation of other systems in those mechanisms, as opioids and other substances, are also shown. The article reinforces the importance, for both physicians and researchers, of an always growing understanding of alcohol central mechanisms of action. This understanding is necessary to new pharmacological options to alcohol harm reduction as well as to alcohol withdrawal treatment.

  8. Bacterial meningitis in alcoholic patients: A population-based prospective study. (United States)

    van Veen, Kiril E B; Brouwer, Matthijs C; van der Ende, Arie; van de Beek, Diederik


    To study clinical features and outcome of community-acquired bacterial meningitis in alcoholic patients. Patients with a history of alcoholism were selected from our nationwide, prospective cohort on community-acquired bacterial meningitis performed from March 2006 to October 2014. Data on patient history, symptoms and signs on admission, treatment, and outcome were prospectively collected. Of 1359 included episodes, 88 episodes (6%) occurred in 88 alcoholic patients. Seizures as presenting symptom were present in 18% alcoholic patients, and 23% presented with co-existing pneumonia. Causative organisms were Streptococcus pneumoniae in 76%, Listeria monocytogenes in 8%, and Neisseria meningitidis in 6% of patients. A high rate of systemic complications occurred with respiratory failure in 40% and endocarditis in 9% of patients. Outcome was unfavorable in 58% of alcoholic patients, and 25% died. Alcoholism was associated with unfavorable outcome in a multivariate analysis (OR 1.96; 95% CI 1.12-3.46; P = 0.019), but not with death (OR 0.76; 95% CI 0.35-1.68; P = 0.762). Alcoholic bacterial meningitis patients often have an unfavorable outcome, which appears to result from a high rate of systemic complications, mainly respiratory failure. Seizures are common in alcoholic patients and warrant caution of development of an alcohol withdrawal syndrome. Copyright © 2017. Published by Elsevier Ltd.

    Full Text Available Audience: This simulation session is appropriate for medical students, community physicians, or residents in emergency medicine, neurology, pediatrics, or family medicine. Introduction: Febrile seizures are the most common form of seizures in childhood; they are thought to occur in 2-5% of all children.1-3 Febrile seizures are defined as a seizure in association with a febrile illness in children without a central nervous system infection, previous afebrile seizure, known brain disorder, or electrolyte abnormalities. 1,2 They typically occur between 6 months and 18 months of age though they can occur up to 5 years of age.3 Febrile seizures are categorized as: simple (generalized seizure lasting less than 15 minutes in a child aged 6 months to 5 years, and less than 1 in a 24 hour period or complex (a focal seizure or generalized seizure lasting greater than 15 minutes, or multiple seizures in a 24 hour period. 1,3 Treatment for febrile seizures is based on treating the underlying cause of the fever and giving reassurance and education to the parents.2 Mortality is extremely rare, and there is no difference in the patient’s cognitive abilities after a febrile seizure, even when the seizure is prolonged.1 Objectives: At the end of this simulation session, the learner will be able to: 1 discuss the management of febrile seizures 2 discuss when placement of an advanced airway is indicated in the management of a febrile seizure 3 list the risk factors for febrile seizures 4 prepare a differential diagnosis for the causes of febrile seizures 5 educate family members on febrile seizures. Methods: This educational session is a high-fidelity simulation.

  11. Seizure disorders and epilepsy. (United States)

    Ozuna, J


    Seizures are uncontrolled hypersynchronous electrical discharges of neurons in the brain that interfere with normal function. They are a symptom of an underlying disorder. Epilepsy is a condition of recurring seizures that do not have a reversible metabolic cause. Seizures can be confused with a variety of other conditions, so an understanding of seizure manifestations is crucial in making an accurate diagnosis. Drug therapy is the mainstay of epilepsy treatment, but surgery and vagal nerve stimulation are options for selected refractory cases. Psychosocial consequences of recurring seizures are often more significant to patients than the seizures themselves.

  14. A differential role for neuropeptides in acute and chronic adaptive responses to alcohol: behavioural and genetic analysis in Caenorhabditis elegans.

    Directory of Open Access Journals (Sweden)

    Philippa Mitchell


    Full Text Available Prolonged alcohol consumption in humans followed by abstinence precipitates a withdrawal syndrome consisting of anxiety, agitation and in severe cases, seizures. Withdrawal is relieved by a low dose of alcohol, a negative reinforcement that contributes to alcohol dependency. This phenomenon of 'withdrawal relief' provides evidence of an ethanol-induced adaptation which resets the balance of signalling in neural circuits. We have used this as a criterion to distinguish between direct and indirect ethanol-induced adaptive behavioural responses in C. elegans with the goal of investigating the genetic basis of ethanol-induced neural plasticity. The paradigm employs a 'food race assay' which tests sensorimotor performance of animals acutely and chronically treated with ethanol. We describe a multifaceted C. elegans 'withdrawal syndrome'. One feature, decrease reversal frequency is not relieved by a low dose of ethanol and most likely results from an indirect adaptation to ethanol caused by inhibition of feeding and a food-deprived behavioural state. However another aspect, an aberrant behaviour consisting of spontaneous deep body bends, did show withdrawal relief and therefore we suggest this is the expression of ethanol-induced plasticity. The potassium channel, slo-1, which is a candidate ethanol effector in C. elegans, is not required for the responses described here. However a mutant deficient in neuropeptides, egl-3, is resistant to withdrawal (although it still exhibits acute responses to ethanol. This dependence on neuropeptides does not involve the NPY-like receptor npr-1, previously implicated in C. elegans ethanol withdrawal. Therefore other neuropeptide pathways mediate this effect. These data resonate with mammalian studies which report involvement of a number of neuropeptides in chronic responses to alcohol including corticotrophin-releasing-factor (CRF, opioids, tachykinins as well as NPY. This suggests an evolutionarily conserved role

  17. Val158Met COMT polymorphism and risk of aggression in alcohol dependence. (United States)

    Soyka, Michael; Zill, Peter; Koller, Gabi; Samochowiec, Agnieszka; Grzywacz, Anna; Preuss, Ulrich W


    Aggression, violence and antisocial behavior are common in alcoholism, but their biological basis is poorly understood. Several studies and recent meta-analyses indicate that in schizophrenia the catecholamine-O-methyltransferase (COMT) Val158Met genotype may be associated with aggression, most often in methionine allele carriers. We tested this hypothesis in a sample of treatment-seeking alcohol-dependent in-patients (293 German patients and 499 controls, and additional 190 Polish patients as replication sample). As expected, patients with a history of violent or non-violent crime were more often male, had an earlier onset of alcoholism and more withdrawal seizures and delirium tremens, and were more likely to have a history of suicide attempts. COMT genotype was not associated with a history of violent or non-violent crime. More studies are needed on the neurobiological basis of aggression and violence in alcoholism. © 2013 Society for the Study of Addiction.

  18. Athletes with seizure disorders. (United States)

    Knowles, Byron Don; Pleacher, Michael D


    Individuals with seizure disorders have long been restricted from participation in certain sporting activities. Those with seizure disorders are more likely than their peers to have a sedentary lifestyle and to develop obesity. Regular participation in physical activity can improve both physical and psychosocial outcomes for persons with seizure disorders. Seizure activity often is reduced among those patients who regularly engage in aerobic activity. Recent literature indicates that the diagnosis of seizure disorders remains highly stigmatizing in the adolescent population. Persons with seizure disorders may be more accepted by peer groups if they are allowed to participate in sports and recreational activities. Persons with seizure disorders are encouraged to participate in regular aerobic activities. They may participate in team sports and contact or collision activities provided that they utilize appropriate protective equipment. There seems to be no increased risk of injury or increasing seizure activity as the result of such participation. Persons with seizure disorders still are discouraged from participating in scuba diving and skydiving. The benefits of participation in regular sporting activity far outweigh any risk to the athlete with a seizure disorder who chooses to participate in sports.

  1. Management of a First Seizure. (United States)

    Bergey, Gregory K


    Assessment of the patient with a first seizure is a common and important neurologic issue. Less than 50% of patients who have a first unprovoked seizure have a second seizure; thus, the evaluation should focus on determining the patient's risk of seizure recurrence. A number of population studies, including some classic reports, have identified the relative risk factors for subsequent seizure recurrence. The 2014 update of the International League Against Epilepsy definition of epilepsy incorporates these findings, and in 2015, the American Academy of Neurology published a guideline that analyzed the available data. Provoked or acute symptomatic seizures do not confer increased risk for subsequent unprovoked seizure recurrence. Multiple seizures in a given 24-hour period do not increase the risk of seizure recurrence. Remote symptomatic seizures, an epileptiform EEG, a significant brain imaging abnormality, and nocturnal seizures are risk factors for seizure recurrence. Antiepileptic drug therapy delays the time to second seizure but may not influence long-term remission.

  2. Seizure semiology and aging. (United States)

    Silveira, Diosely C; Jehi, Lara; Chapin, Jessica; Krishnaiengar, Suparna; Novak, Eric; Foldvary-Schaefer, Nancy; Najm, Imad


    The incidence of epilepsy is high in older individuals. However, epilepsy in the elderly may be underdiagnosed and undertreated because of diagnostic difficulties. The main goal of this study was to determine whether seizure semiology differs between older and younger adults with epilepsy in the outpatient setting. Fifty patients with focal epilepsy aged 55 years and older and 50 patients aged between 18 and 45 years were included. Review of medical records contained detailed seizure description. There were no differences in seizure semiology between groups, except that subtle perceptions of transient confusion were seen in older patients but not in younger patients (P=0.0028). Older patients had less generalized motor seizures, but the differences between groups did not reach significance (P=0.01). Older patients may present with subtle symptoms of seizures characterized by brief periods of confusion, which may contribute to greater difficulty diagnosing seizures in the elderly.

  3. Impact of alcohol intoxication and withdrawal syndrome on social phobia and panic disorder in alcoholic inpatients Impacto das fases de intoxicação e de abstinência de álcool sobre a fobia social e o transtorno de pânico em pacientes alcoolistas hospitalizados

    Directory of Open Access Journals (Sweden)

    Mauro Barbosa Terra


    Full Text Available PURPOSE: To investigate the impact of alcohol intoxication and withdrawal on the course of social phobia and panic disorder. METHOD: A group of 41 alcoholic inpatients undergoing detoxification therapy were interviewed using the SCID-I (DSM-IV and questions to detect fluctuations in the course of social phobia and panic disorder as a function of the different phases in alcohol dependence (intoxication, withdrawal, and lucid interval. RESULTS: Only 1 (2.4% patient presented panic disorder throughout life, and 9 (21.9% had panic attacks during alcohol intoxication or during the withdrawal syndrome. Sixteen (39% alcoholic patients showed social phobia with onset prior to drug use. However, drinking eventually became unable to alleviate social phobia symptoms or worsened such symptoms in 31.2% of social-phobic patients. While patients with social phobia reported a significant improvement in psychiatric symptoms during alcohol intoxication, patients experiencing panic attacks worsened significantly during intoxication. In the withdrawal phase, patients with social phobia tended to have more and more intense phobic symptoms. CONCLUSION: Our findings indicate that the impact of alcohol intoxication is different for social phobia as compared to panic disorder, at first decreasing the social-phobic symptoms but later aggravating them. In panic disorder, the impact of intoxication by alcohol is more harmful, at least in the short term.OBJETIVO: Estudar o impacto das fases de intoxicação e de abstinência do uso de álcool sobre o curso da fobia social e do transtorno de pânico.

  4. Value and limitations of seizure semiology in localizing seizure onset. (United States)

    So, Elson L


    Seizure semiology has been the foundation of clinical diagnosis of seizure disorders. This article discusses the value and the limitations of behavioral features of seizure episodes in localizing seizure onset. Studies have shown that some semiologic features of seizures are highly accurate in the hemispheric lateralization and lobar localization of seizures. There is good agreement between blinded reviewers in lateralizing video-recorded seizures in temporal lobe and extratemporal lobe epilepsies. However, seizure semiology alone should not be used to determine the site of seizure onset. Each semiologic feature may falsely localize seizure onset. Seizure semiology in some patients may signify the site of seizure propagation rather than origination. Moreover, seizure semiology may not be as reliable in multifocal epilepsies as it is in unifocal epilepsies. Many semiologic features of seizures of adults are often missing in seizures of children. Seizure semiology should be analyzed and integrated with EEG and neuroimaging data to localize the seizure focus. A sample of the recorded seizures should be shown to the patient's relatives or friends to verify that it is representative of habitual seizures.

    Full Text Available A síndrome de abstinência alcoólica é um quadro agudo, caracterizado por um conjunto de sinais e sintomas autolimitados, com gravidade variada, secundário à interrupção total ou parcial do consumo de álcool, podendo ser associado a inúmeros problemas clínicos e/ou outros transtornos psiquiátricos. O objetivo deste artigo é rever as principais complicações psiquiátricas secundárias à síndrome de abstinência alcoólica, como convulsões e delirium tremens, bem como algumas outras condições psiquiátricas associadas à dependência de álcool, como as síndromes de Wernicke Korsakoff e de Marchiava Bignami. Pretende-se, com isso, auxiliar no diagnóstico precoce e tratamento adequado, minimizando assim a morbidade e a mortalidade associadas a tais complicações.Alcohol withdrawal syndrome is an acute condition secondary to total or partial reduction of alcohol consumption, characterized by self limited signs and symptoms and different degrees of severity. It can be complicated by several clinical and/or other psychiatric related problems. The objective of this article is to review the most important psychiatric complications to alcohol withdrawal syndrome as well as other psychiatric disorders associated with alcohol dependence as Wernicke Korsakoff and Marchiava Bignami syndromes. We aim to promote early diagnosis and treatment of these conditions, minimizing morbidity and mortality associated with them.

  6. The negative effects of alcohol hangover on high-anxiety phenotype rats are influenced by the glutamate receptors of the dorsal midbrain. (United States)

    Ezequiel Leite, L; Nobre, M J


    Alcoholism is a chronic disorder characterized by the appearance of a withdrawal syndrome following the abrupt cessation of alcohol intake that includes symptoms of physical and emotional disturbances, anxiety being the most prevalent symptom. In humans, it was shown that anxiety may increase the probability of relapse. In laboratory animals, however, the use of anxiety to predict alcohol preference has remained difficult. Excitatory amino acids as glutamate have been implicated in alcohol hangover and may be responsible for the seizures and anxiety observed during withdrawal. The dorsal periaqueductal gray (DPAG) is a midbrain region critical for the modulation/expression of anxiety- and fear-related behaviors and the propagation of seizures induced by alcohol withdrawal, the glutamate neurotransmission being one of the most affected. The present study was designed to evaluate whether low- (LA) and high-anxiety rats (HA), tested during the alcohol hangover phase, in which anxiety is the most prevalent symptom, are more sensitive to the reinforcing effects of alcohol when tested in a voluntary alcohol drinking procedure. Additionally, we were interested in investigating the main effects of reducing the excitatory tonus of the dorsal midbrain, after the blockade of the ionotropic glutamate receptors into the DPAG, on the voluntary alcohol intake of HA and LA motivated rats that were made previously experienced with the free operant response of alcohol drinking. For this purpose, we used local infusions of the N-metil D-Aspartato (NMDA) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-kainate receptors antagonist DL-2-Amino-7-phosphonoheptanoic acid - DL-AP7 (10 nmol/0.2 μl) and l-glutamic acid diethyl ester - GDEE (160 nmol/0.2 μl), respectively. Alcohol intoxication was produced by 10 daily bolus intraperitonial (IP) injections of alcohol (2.0 g/kg). Peak-blood alcohol levels were determined by gas-chromatography analysis in order to assess blood-alcohol

  7. [Alcohol dependence and anxious disorders: dangerous liaisons]. (United States)

    Gorwood, Philip


    Anxiety disorders and alcohol dependence have a higher co-occurence than expected by chance only. This association has a double origin, as the presence of alcohol dependence increases by 6 the risk of any anxious disorder, and the presence of an anxious disorder multiply by 3 the risk of alcohol-dependence. Interestingly, a large population-based epidemiological study performed 10 years apart clearly showed that anxiety disorders moderatly increase the risk of regular consumption in non-consumers or irregular drinkers (by 70%), does not increase ther risk of abuse in regular drinkers, but has a strong impact on the risk of alcohol dependence while already an abuser (OR = 2.7). Assessing the kinetic of symptoms of anxiety and focusing on some symptoms that are more specific than others (for example nausea, vomiting and/or shaking hands in the morning, all being relieved by the first drink) is helpful. Treating anxiety symptoms in alcohol dependence means, whatever the type of relationship they have, to begin with a detoxification program. Indeed, antidepresants have a larger liver-toxicity in alcohol dependence, and benzodiazepine loose most of their benefits with high level of alcohol consumption. Furthermore, when benzodiazepines are taken with large doses of alcohol, the risk of severe withdrawal symptoms is increased (such as seizures). The same trend could be proposed for psychotherapy, as cognitive behavioural therapy sollicitates a lot executive functions. The neurotoxicity of alcohol explains the damages on executive functions, CBT therefore should have larger efficacy after the detoxification program, helping to reduce the risk of relapse.

  12. Reliability of seizure semiology in patients with 2 seizure foci. (United States)

    Rathke, Kevin M; Schäuble, Barbara; Fessler, A James; So, Elson L


    To determine whether seizure semiology is reliable in localizing and distinguishing seizures at 2 independent brain foci in the same patient. Two masked reviewers localized seizures from 2 foci by their clinical semiology and intracranial electroencephalograms (EEGs). Epilepsy monitoring unit of referral comprehensive epilepsy program. Seventeen consecutive patients (51 seizures) with sufficient video and intracranial EEG data were identified by reviewing medical records of 366 patients older than 10 years. The primary outcome measures were interobserver agreement between the 2 masked reviewers; the proportion of seizures localized by semiology; the proportion of localized seizures concordant with intracranial EEG localization; and comparison between concordant and nonconcordant seizures in latency of intracranial EEG seizure spread. Interobserver agreement was 41% (κ score, 0.16). Only 30 of 51 seizures (59%) were localized by seizure semiology. The focus localized by semiology was concordant with the location of intracranial EEG seizure onset in 16 of 30 seizures (53%). No significant difference was observed between concordant and nonconcordant seizures in relation to the speed with which the EEG discharge spread from the location of seizure onset to another lobar region (P = .09, Wilcoxon rank sum test). Clinical seizure semiology is not as useful as intracranial EEG in localizing seizure onset in patients with dual seizure foci.

    The purpose of this case-matched study was to determine how frequently fibromyalgia is associated with different paroxysmal neurological disorders and explore the utility of fibromyalgia as a predictor for the diagnosis of psychogenic non-epileptic seizures. The billing diagnosis codes of 1,730 new, non-selected patient encounters were reviewed over a three-year period for an epileptologist in a neurology clinic to identify all patients with historical diagnoses of fibromyalgia. The frequency with which epileptic seizures, psychogenic non-epileptic seizures, and physiological non-epileptic events were comorbid with fibromyalgia was assessed. Age and gender case-matched controls were used for a between-group comparison. Wilcoxon tests were used to analyse interval data, and Chi-square was used to analyse categorical data (pFibromyalgia was retrospectively identified in 95/1,730 (5.5%) patients in this cohort. Females represented 95% of the fibromyalgia sample (age: 53 years; 95% CI: 57, 51). Forty-three percent of those with fibromyalgia had a non-paroxysmal, neurological primary clinical diagnosis, most commonly chronic pain. Paroxysmal events were present in 57% of fibromyalgia patients and 54% of case-matched controls. Among patients with fibromyalgia and paroxysmal disorders, 11% had epileptic seizures, 74% had psychogenic non-epileptic seizures, and 15% had physiological non-epileptic events, compared to case-matched controls with 37% epileptic seizures, 51% psychogenic non-epileptic events, and 12% physiological non-epileptic events (p = 0.009). Fibromyalgia was shown to be a predictor for the diagnosis of psychogenic non-epileptic seizures in patients with undifferentiated paroxysmal spells. However, our results suggest that the specificity and sensitivity of fibromyalgia as a marker for psychogenic non-epileptic seizures in a mixed general neurological population of patients is less than previously described.

  17. Seizures Induced by Music

    Directory of Open Access Journals (Sweden)

    A. O. Ogunyemi


    Full Text Available Musicogenic epilepsy is a rare disorder. Much remains to be learned about the electroclinical features. This report describes a patient who has been followed at our institution for 17 years, and was investigated with long-term telemetered simultaneous video-EEG recordings. She began to have seizures at the age of 10 years. She experienced complex partial seizures, often preceded by elementary auditory hallucination and complex auditory illusion. The seizures occurred in relation to singing, listening to music or thinking about music. She also had occasional generalized tonic clonic seizures during sleep. There was no significant antecedent history. The family history was negative for epilepsy. The physical examination was unremarkable. CT and MRI scans of the brain were normal. During long-term simultaneous video-EEG recordings, clinical and electrographic seizure activities were recorded in association with singing and listening to music. Mathematical calculation, copying or viewing geometric patterns and playing the game of chess failed to evoke seizures.

  18. Neonatal opioid withdrawal syndrome. (United States)

    Sutter, Mary Beth; Leeman, Lawrence; Hsi, Andrew


    Neonatal opioid withdrawal syndrome is common due to the current opioid addiction epidemic. Infants born to women covertly abusing prescription opioids may not be identified as at risk until withdrawal signs present. Buprenorphine is a newer treatment for maternal opioid addiction and appears to result in a milder withdrawal syndrome than methadone. Initial treatment is with nonpharmacological measures including decreasing stimuli, however pharmacological treatment is commonly required. Opioid monotherapy is preferred, with phenobarbital or clonidine uncommonly needed as adjunctive therapy. Rooming-in and breastfeeding may decease the severity of withdrawal. Limited evidence is available regarding long-term effects of perinatal opioid exposure. Copyright © 2014 Elsevier Inc. All rights reserved.

  2. Patterns of epileptic seizure occurrence. (United States)

    Amengual-Gual, Marta; Sánchez Fernández, Iván; Loddenkemper, Tobias


    The occurrence of epileptic seizures in seemingly random patterns takes a great toll on persons with epilepsy and their families. Seizure prediction may markedly improve epilepsy management and, therefore, the quality of life of persons with epilepsy. Literature review. Seizures tend to occur following complex non-random patterns. Circadian oscillators may contribute to the rhythmic patterns of seizure occurrence. Complex mathematical models based on chaos theory try to explain and even predict seizure occurrence. There are several patterns of epileptic seizure occurrence based on seizure location, seizure semiology, and hormonal factors, among others. These patterns are most frequently described for large populations. Inter-individual variability and complex interactions between the rhythmic generators continue to make it more difficult to predict seizures in any individual person. The increasing use of large databases and machine learning techniques may help better define patterns of seizure occurrence in individual patients. Improvements in seizure detection -such as wearable seizure detectors- and in seizure prediction -such as machine learning techniques and artificial as well as biological intelligence- promise to provide further progress in the field of epilepsy and are being applied to closed-loop systems for the treatment of epilepsy. Seizures tend to occur following complex and patient-specific patterns despite their apparently random occurrence. A better understanding of these patterns and current technological advances may allow the implementation of closed-loop detection, prediction, and treatment systems in routine clinical practice.

  3. Improving early seizure detection. (United States)

    Jouny, Christophe C; Franaszczuk, Piotr J; Bergey, Gregory K


    Over the last decade, the search for a method able to reliably predict seizures hours in advance has been largely replaced by the more realistic goal of very early detection of seizure onset, which would allow therapeutic or warning devices to be triggered prior to the onset of disabling clinical symptoms. We explore in this article the steps along the pathway from data acquisition to closed-loop applications that can and should be considered to design the most efficient early seizure detection. Microelectrodes, high-frequency oscillations, high sampling rate, high-density arrays, and modern analysis techniques are all elements of the recording and detection process that in combination with modeling studies can provide new insights into the dynamics of seizure onsets. Each of these steps needs to be considered if detection devices that will favorably impact the quality of life of patients are to be implemented.

  4. Herbal mixtures consisting of puerarin and either polyenylphosphatidylcholine or curcumin provide comprehensive protection against alcohol-related disorders in P rats receiving free choice water and 15% ethanol in pure water. (United States)

    Singh, Ashok K; Jiang, Yin; Benlhabib, Elhabib; Gupta, Shveta


    Chronic alcohol drinking has been associated with the development of a number of abnormalities, including neuron-behavioral disorders, liver, pancreas, and heart-related diseases and inflammation and immune disorders. Because diverse mechanisms are involved in the development of these disorders, the commonly used receptor- or enzyme-specific drugs do not provide comprehensive protection against the adverse effects of alcoholism. This study describes possible therapeutic potency of puerarin (PU) from kudzu root, polyenylphosphatidylcholine from soy (SPCh), and curcumin (CU) from turmeric against alcohol's addiction-related and inflammatory-related abnormalities in alcohol-preferring P rats receiving free choice water and 15% ethanol in water. P-rats were fed once daily either the vehicle (for control) or different doses of PU, SPCh, CU, PU + SPCh, or PU + CU. The rats were divided in two groups: one received water alone, and the other free choice water and ethanol. Four rats from each group were fitted with electroencephalogram (EEG) electrodes for EEG recording. After 70 days of alcohol drinking, alcohol was withdrawn for 2 weeks, and the withdrawal symptoms were assessed. This study showed that alcohol drinking for 70 days (1) caused liver inflammation characterized by elevated tumor necrosis factor-alpha, interleukin-1beta, and matrix metalloproteinase-9 expression and (2) dysregulated lipopolysaccharide (LPS)-induced pleurisy. Alcohol withdrawal after 70 days of drinking generated severe withdrawal symptoms including seizure-type EEG activity. PU suppressed the addiction-mediated abnormalities but did not affect the inflammation-related abnormalities, while SPCh or CU suppressed only the inflammation-related abnormalities in alcohol-drinking rats subjected to LPS-induced pleurisy. A combination of PU with SPCh or CU suppressed both the addiction-related and inflammation-related abnormalities of alcohol drinking. Therefore, a mixture consisting of PU and either

    1 The effects of subacute treatment with cannabidiol, delta 9-tetrahydrocannabinol (delta 9-THC), phenytoin and phenobarbitone on anticonvulsant activity and on withdrawal excitability in mice were compared in three electrically induced seizure-threshold tests. 2 In the maximal electroshock-threshold test, subacute treatment did not alter the anticonvulsant activity of cannabidiol, phenytoin or phenobarbitone, but tolerance developed to delta 9-THC. 3 In the 60 Hz electroshock-threshold test, the activity of delta 9-THC and cannabidiol did not change, but tolerance developed to phenobarbitone, and there was an increase in sensitivity to phenytoin. 4 In the 6 Hz electroshock-threshold test, there was an increase in sensitivity to both delta 9-THC and cannabidiol, there was tolerance to phenobarbitone, while the activity of phenytoin did not change. 5 Although tolerance developed in some of the seizure-threshold tests to delta 9-THC and phenobarbitone, tolerance to cannabidiol and phenytoin did not develop in any of the tests. 6 Hyperexcitability followed withdrawal from only delta 9-THC (6 Hz and 60 Hz electroshock-threshold tests) and phenobarbitone (maximal electroshock-threshold and 60 Hz electroshock-threshold tests). 7 The delta 9-THC withdrawal hyperexcitability suggests that the use of marihuana may jeopardize the control of seizures in epileptics.

  8. Visualization of groundwater withdrawals (United States)

    Winston, Richard B.; Goode, Daniel J.


    Generating an informative display of groundwater withdrawals can sometimes be difficult because the symbols for closely spaced wells can overlap. An alternative method for displaying groundwater withdrawals is to generate a “footprint” of the withdrawals. WellFootprint version 1.0 implements the Footprint algorithm with two optional variations that can speed up the footprint calculation. ModelMuse has been modified in order to generate the input for WellFootprint and to read and graphically display the output from WellFootprint.

    Several different terms have been used to describe "psychogenic nonepileptic seizures" (PNES) in the literature. In this study, we evaluated the most common English terms used to describe PNES on Google and in PubMed using multiple search terms ( and The information prevalence of the five terms most frequently used to refer to PNES in PubMed were: psychogenic non(-)epileptic seizure(s), followed by pseudo(-)seizure(s), non(-)epileptic seizure(s), psychogenic seizure(s), and non(-)epileptic event(s). The five most frequently adopted terms to describe PNES in Google were: psychogenic non(-)epileptic seizure(s), followed by non(-)epileptic event(s), psychogenic attack(s), non(-)epileptic attack(s), and psychogenic non(-)epileptic attack(s). The broad spectrum of synonyms used to refer to PNES in the medical literature reflects a lack of internationally accepted, uniform terminology for PNES. In addition to "seizure(s)," lay people use the word "attack(s)" to describe PNES. Although considered obsolete, some terms, e.g., pseudoseizure(s), are still used in the recent medical literature. Adopting a uniform terminology to describe PNES could facilitate communication between epileptologists, physicians without specific expertise in epilepsy, and patients.

  12. Effect of medication withdrawal on the interictal epileptiform EEG discharges in presurgical evaluation

    DEFF Research Database (Denmark)

    Andersen, N.B.; Alving, J.; Beniczky, S.


    Medication withdrawal (MW) is an important method of provoking seizures and activating epileptiform EEG activity during the diagnostic work-up of patients evaluated for epilepsy surgery. Previously it was suggested that MW might influence the seizure-type and activate cortical areas otherwise...... not producing epileptiform discharges, leading to a false localization of the irritative zone. In order to investigate this we reviewed 42 consecutive cases of MW, of 36 patients, during a 3-year period. We compared seizure frequency, seizure-types and the localization of interictal epileptiform discharges...... MW. In one-third of the patients the interictal EEGs after the MW were different from those recorded before the MW. However, in these discordant cases the EEG findings after the MW (and not before the MW) were concordant with the seizure onset zone and the lesional zone. We conclude that MW...

  15. Stopping epilepsy treatment in seizure remission: Good or bad or both? (United States)

    Schmidt, Dieter; Sillanpää, Matti


    To review the outcome of epilepsy after stopping antiepileptic drugs in remission. Stopping antiepileptic drugs (AEDs) in remission is routinely done in many patients. Although the consequences of an unexpected relapse seizure in the 2 years after stopping AEDs may cause anguish and social issues, the impact on the long term seizure outlook of the epilepsy is minimal, if any. Discontinuation of drug treatment does not seem to affect the long-term prognosis but exposes patients who were seizure-free for years to a transient two-fold risk of seizures for the first 2 years after stopping AEDs. In addition, 20% of patients who were seizure-free for years, do not become seizure-free immediately after restarting AED treatment after relapse. The list of potential pitfalls is long. Patients with juvenile myoclonic epilepsy, those with prior withdrawal attempts and late remission have a higher risk of relapse. Stopping AEDs in remission does not affect the long-term patterns of epilepsy and some patients report a better general health in a life without AEDs. High-risk patients should not be generally encouraged to stop their AEDs in remission. We need new drugs that combine anti-seizure and antiepileptogenic effects to prevent seizure relapse and flare up of epilepsy after stopping AEDs in remission.

  16. The paradox of the paroxysm: can seizure precipitants help explain human ictogenesis? (United States)

    Huberfeld, Gilles; Le Duigou, Caroline; Le Van Quyen, Michel; Navarro, Vincent; Baulac, Michel; Miles, Richard


    An epileptic brain is permanently in a diseased state, but seizures occur rarely and without warning. Here we examine this paradox, common to paroxysmal diseases. We review the problem in the context of the prototypic acquired epilepsies of the medial temporal lobe. We ask how an epileptic temporal lobe differs from a healthy one and examine biological mechanisms that may explain the transition to seizure. Attempts to predict seizure timing from analyses of brain electrical activity suggest that the neurological processes involved may be initiated significantly before a seizure. Furthermore, whereas seizures are said to occur without warning, some patients say they know when a seizure is imminent. Several factors, including sleep deprivation, oscillations in hormonal levels, or withdrawal from drugs, increase the probability of a seizure. We ask whether these seizure precipitants might act through common neuronal mechanisms. Several precipitating factors seem to involve relief from a neurosteroid modulation of gamma-amino butyric acid receptor type A (GABAA) receptors. We propose tests of this hypothesis.

    The mechanism of the antidepressant effect of bupropion is not fully understood. Besides, using it in the treatment of depression, it is found to be effective in reducing withdrawal symptoms due to smoking cessation. A 28-year-old female patient with a history of depression was admitted to emergency department an hour after ingestion of bupropion, quetiapine, and levothyroxine in high doses to commit suicide. While accepting her into the Intensive Care Unit, she was awake, alert, disoriented and agitated. After 2h, the patient had a generalized tonic-clonic seizure. The necessary treatment was given and 9h later with hemodynamic improvement, the patients' mental status improved. Bupropion may cause unusual behaviors such as delusions, paranoia, hallucinations, or confusion. The risk of seizure is strongly dose-dependent. We want to emphasize the importance of early gastric lavage and administration of activated charcoal. Copyright © 2014 Sociedade Brasileira de Anestesiologia. Published by Elsevier Editora Ltda.

    Seven patients with opioid dependence admitted in the de-addiction centre for detoxification developed convulsions and delirium during the withdrawal phase. After ruling out all other possible causes of these complications, opioid withdrawal seemed to emerge as the most likely explanation. The unpredictability of the course of opioid dependence and withdrawal needs to be considered when treating patients with opioid dependence.

  19. Recurrent seizures after lidocaine ingestion. (United States)

    Aminiahidashti, Hamed; Laali, Abolghasem; Nosrati, Nazanin; Jahani, Fatemeh


    Lidocaine has a concentration-dependent effect on seizures. Concentrations above 15 μg/mL frequently result in seizures in laboratory animals and human. We report a case of central nervous system (CNS) lidocaine toxicity and recurrent seizure after erroneous ingestion of lidocaine solution. A 4-year-old boy presented to the Emergency Department of Imam Hospital of Sari in December 2013 due to tonic-clonic generalized seizures approximately 30 min ago. 3 h before seizure, his mother gave him 2 spoons (amount 20-25 cc) lidocaine hydrochloride 2% solution instead of pediatric gripe by mistake. Seizure with generalized tonic-clonic occurred 3 times in home. Neurological examination was essentially unremarkable except for the depressed level of consciousness. Personal and medical history was unremarkable. There was no evidence of intracranial ischemic or hemorrhagic lesions in computed tomography scan. There were no further seizures, the condition of the patient remained stable, and he was discharged 2 days after admission. The use of viscous lidocaine may result in cardiovascular and CNS toxicity, particularly in children. Conservative management is the best option for treatment of lidocaine induced seizure.

    Vendrame, Martina; Zarowski, Marcin; Alexopoulos, Andreas V; Wyllie, Elaine; Kothare, Sanjeev V; Loddenkemper, Tobias


    The aim of this study was to evaluate the relationship between semiology of seizures in children and adolescents to the corresponding EEG localization. Charts of 225 consecutive pediatric epilepsy patients undergoing Video-EEG monitoring (VEM) over 2 years were reviewed. Seizure semiology recorded during VEM was classified according to ILAE seizure semiology terminology and EEG localization, and analyzed based on onset as defined by the EEG data (generalized, frontal, temporal, parietal, occipital or multilobar). A total of 1008 seizures were analyzed in 225 children (mean age 8.5 years, range 0-20), with 50% boys. Auras and seizures with automatisms arose predominantly from the temporal lobes (psemiologies relate to specific brain regions, with overlap between focal and generalized semiological seizure types, as identified electrographically. Semiology of seizures can provide important information for epilepsy localization, and should not be overlooked, especially in patients undergoing pre-surgical evaluation. Separation of clinical seizure description and EEG findings may be useful, in particular when only incomplete information is available. i.e. during the first office visit.

  1. Differential changes in amygdala and frontal cortex Pde10a expression during acute and protracted withdrawal

    Directory of Open Access Journals (Sweden)

    Marian L Logrip


    Full Text Available Alcohol use disorders are persistent problems with high recidivism rates despite repeated efforts to quit drinking. Neuroadaptations that result from alcohol exposure and that persist during periods of abstinence represent putative molecular determinants of the propensity to relapse. Previously we demonstrated a positive association between phosphodiesterase 10A (PDE10A gene expression and elevations in relapse-like alcohol self-administration in rats with a history of stress exposure. Because alcohol withdrawal is characterized by heightened anxiety-like behavior, activation of stress-responsive brain regions and an elevated propensity to self-administer alcohol, we hypothesized that Pde10a expression also would be upregulated in reward- and stress-responsive brain regions during periods of acute (8-10 h and protracted (6 wk alcohol withdrawal. During acute withdrawal, elevated Pde10a mRNA expression was found in the medial and basolateral amygdala, as well as the infralimbic and anterior cingulate subdivisions of the medial prefrontal cortex, relative to alcohol-naïve controls. The basolateral amygdala was the only region with elevated Pde10a mRNA expression during both acute and protracted withdrawal. In contrast to the elevations, Pde10a mRNA levels tended to be reduced during protracted withdrawal in the dorsal striatum, prelimbic prefrontal cortex, and medial amygdala. Together these results implicate heightened PDE10A expression in the basolateral amygdala as a lasting neuroadaptation associated with alcohol dependence.

  2. Epilepsy: accuracy of patient seizure counts. (United States)

    Hoppe, Christian; Poepel, Annkathrin; Elger, Christian E


    To evaluate the effects of a daily patient reminder on seizure documentation accuracy. Randomized controlled trial. Monitoring unit of an academic department of epileptology. Patients Consecutive sample of 91 adult inpatients with focal epilepsies undergoing video-electroencephalographic monitoring. Intervention While all patients were asked to document seizures at the beginning of the monitoring period, patients from the experimental group were reminded each day to document seizures. Main Outcome Measure Documentation accuracy (percentage of documented seizures). A total of 582 partial seizures were recorded. Patients failed to document 55.5% of all recorded seizures, 73.2% of complex partial seizures, 26.2% of simple partial seizures, 41.7% of secondarily generalized tonic-clonic seizures, 85.8% of all seizures during sleeping, and 32.0% of all seizures during the awake state. The group medians of individual documentation accuracies for overall seizures, simple partial seizures, complex partial seizures, and secondarily generalized tonic-clonic seizures were 33.3%, 66.7%, 0%, and 83.3%, respectively. Neither the patient reminder nor cognitive performance affected documentation accuracy. A left-sided electroencephalographic focus or lesion, but not the site (frontal or temporal), contributed to documentation failure. Patient seizure counts do not provide valid information. Documentation failures result from postictal seizure unawareness, which cannot be avoided by reminders. Unchanged documentation accuracy is a prerequisite for the use of patient seizure counts in clinical trials and has to be demonstrated in a subsample of patients undergoing electroencephalographic monitoring.

  3. [Reflex seizures, cinema and television]. (United States)

    Olivares-Romero, Jesús


    In movies and television series are few references to seizures or reflex epilepsy even though in real life are an important subgroup of total epileptic syndromes. It has performed a search on the topic, identified 25 films in which they appear reflex seizures. Most seizures observed are tonic-clonic and visual stimuli are the most numerous, corresponding all with flashing lights. The emotions are the main stimuli in higher level processes. In most cases it is not possible to know if a character suffers a reflex epilepsy or suffer reflex seizures in the context of another epileptic syndrome. The main conclusion is that, in the movies, the reflex seizures are merely a visual reinforcing and anecdotal element without significant influence on the plot.

  4. Cardiac asystole in partial seizures. (United States)

    Scott, C A; Fish, D R


    Literature review shows many anecdotal case reports of cardiac asystole in ictal recordings of partial seizures. We have reviewed our data from the last five years, of patients who are being assessed for epilepsy surgery and found 2 out of more than 1,500 complex partial seizures, recorded in 589 consecutive patients, showing a significant period of asystole (13 and 15 seconds). Our previous studies of cardiac and respiratory parameters during partial seizures showed that a central apnoea occurred in 39%. It is probable that sudden death during seizures is due to the interaction of both cardiac and respiratory irregularities. Although rare (occurrence cardiac asystole occurring in an epilepsy monitoring unit highlights the need for resuscitation equipment to be readily available and for trained nursing staff. Furthermore, it is important to recognize that the semiology of seizures may be affected by the consequences of secondary cardiac asystole.

  6. Predicting epileptic seizures in advance.

    Directory of Open Access Journals (Sweden)

    Negin Moghim

    Full Text Available Epilepsy is the second most common neurological disorder, affecting 0.6-0.8% of the world's population. In this neurological disorder, abnormal activity of the brain causes seizures, the nature of which tend to be sudden. Antiepileptic Drugs (AEDs are used as long-term therapeutic solutions that control the condition. Of those treated with AEDs, 35% become resistant to medication. The unpredictable nature of seizures poses risks for the individual with epilepsy. It is clearly desirable to find more effective ways of preventing seizures for such patients. The automatic detection of oncoming seizures, before their actual onset, can facilitate timely intervention and hence minimize these risks. In addition, advance prediction of seizures can enrich our understanding of the epileptic brain. In this study, drawing on the body of work behind automatic seizure detection and prediction from digitised Invasive Electroencephalography (EEG data, a prediction algorithm, ASPPR (Advance Seizure Prediction via Pre-ictal Relabeling, is described. ASPPR facilitates the learning of predictive models targeted at recognizing patterns in EEG activity that are in a specific time window in advance of a seizure. It then exploits advanced machine learning coupled with the design and selection of appropriate features from EEG signals. Results, from evaluating ASPPR independently on 21 different patients, suggest that seizures for many patients can be predicted up to 20 minutes in advance of their onset. Compared to benchmark performance represented by a mean S1-Score (harmonic mean of Sensitivity and Specificity of 90.6% for predicting seizure onset between 0 and 5 minutes in advance, ASPPR achieves mean S1-Scores of: 96.30% for prediction between 1 and 6 minutes in advance, 96.13% for prediction between 8 and 13 minutes in advance, 94.5% for prediction between 14 and 19 minutes in advance, and 94.2% for prediction between 20 and 25 minutes in advance.

  7. First seizure: EEG and neuroimaging following an epileptic seizure. (United States)

    Pohlmann-Eden, Bernd; Newton, Mark


    An early EEG (within 48 h) and high-resolution magnetic resonance imaging (hr_MRI) are the methods of choice for an accurate diagnosis after a first seizure presentation. Together with a careful history and examination, they will allow definition of the epilepsy syndrome in two-thirds of patients and help assess the individual risk for seizure recurrence, which is determined by the specific syndrome and is highest with focal epileptiform activity on EEG. Despite the heterogeneity of first seizure studies, EEG and etiology are consistently found to be the best predictors for seizure recurrence and prognosis. The additional yield of sleep-deprived EEG and sleep EEG is uncertain; yet MRI is essential for detecting brain tumors and other structural bases for new epilepsy. The rate occurrence of remote symptomatic seizures increases significantly with age and the most common etiology in the elderly with a first seizure is stroke; however, its exact relevance to epileptogenicity is yet to be defined. There is a striking lack of systematic studies using early EEG and hr_MRI in order to better characterize epileptogenic areas and elucidate the mechanisms of seizure provocation.

  8. Patients' and neurologists' perception of epilepsy and psychogenic nonepileptic seizures. (United States)

    Whitehead, Kimberley; Kandler, Rosalind; Reuber, Markus


    Although differences in illness perceptions between neurologists and patients with epilepsy or psychogenic nonepileptic seizures (PNES) are likely to be clinically relevant, this is the first study to attempt a direct comparison. In addition, this study compares the illness perceptions of patients with epilepsy with those of patients with PNES. Thirty-four patients with epilepsy, 40 patients with PNES, and 45 neurologists were recruited. All patient participants completed versions of the illness perception questionnaire revised (IPQ-R) adapted for epileptic or nonepileptic seizure disorders, single-item symptom attribution question (SAQ), Hospital Anxiety and Depression Scale (HADS), Quality of Life in Epilepsy-31 (QOLIE-31), and Liverpool Seizure Severity Scale (LSSS). Participating neurologists completed two versions of the IPQ-R and two SAQs for epileptic and nonepileptic seizure disorders. Differences in illness perceptions between patients with epilepsy and patients with PNES were minor compared to those between patients with either seizure disorder and neurologists. Neurologists considered both seizure disorders more treatable and more amenable to personal control than did the patients themselves. Neurologists had much more polarized views of the etiology of both conditions; whereas patients mostly considered the causes of their seizure disorders as partially "physical" and partially "psychological," neurologists perceived epilepsy as an essentially "physical" and PNES as a clearly "psychological" problem. There are considerable differences between the illness perceptions of patients with seizure disorders and their doctors, which could represent barriers to successful clinical management. In particular, a discrepancy between neurologists' and patients' beliefs about the personal control that patients may be able to exert over PNES could contribute to the confusion or anger some patients report after the diagnosis has been explained to them. Furthermore

  9. Febrile seizures. Update and controversies. (United States)

    Jan, Mohammed M; Girvin, John P


    Febrile seizures are the most common seizure disorder in children younger than 5 years of age. Most febrile seizures are brief, do not require any specific treatment or workup, and have benign prognoses. Generalists and pediatricians are frequently faced with anxious parents and are required to make rational decisions regarding the need to investigate and treat such a child. They subsequently need to provide further prognostic information and counseling to the families. The aim of this article is to provide an updated overview of febrile seizures and review the most recent diagnostic and therapeutic recommendations. Despite the progress in the understanding of this benign syndrome, a wide variation in physician evaluation and management persists. However, there is recent evidence that pediatricians are becoming more selective in admitting and investigating children with febrile seizures. Admitted children frequently had complex seizures, status epilepticus, or were ill looking. Considering the full scope of febrile seizures, the yield of investigations that might alter management remains low and does not justify extensive work-up or prolonged hospitalization.

  10. Effects of acute withdrawal on ethanol-induced conditioned place preference in DBA/2J mice. (United States)

    Dreumont, Sarah E; Cunningham, Christopher L


    Reexposure to ethanol during acute withdrawal might facilitate the transition to alcoholism by enhancing the rewarding effect of ethanol. The conditioned place preference (CPP) procedure was used to test whether ethanol reward is enhanced during acute withdrawal. DBA/2J mice were exposed to an unbiased one-compartment CPP procedure. Ethanol (0.75, 1.0, or 1.5 g/kg IP) was paired with a distinctive floor cue (CS+), whereas saline was paired with a different floor cue (CS-). The withdrawal (W) group received CS+ trials during acute withdrawal produced by a large dose of ethanol (4 g/kg) given 8 h before each trial. The no-withdrawal (NW) group did not experience acute withdrawal during conditioning trials but was matched for acute withdrawal experience. Floor preference was tested in the absence of ethanol or acute withdrawal. All groups eventually showed a dose-dependent preference for the ethanol-paired cue, but development of CPP was generally more rapid and stable in the W groups than in the NW groups. Acute withdrawal suppressed the normal activating effect of ethanol during CS+ trials, but there were no group differences in test activity. Acute withdrawal enhanced ethanol's rewarding effect as indexed by CPP. Since this effect depended on ethanol exposure during acute withdrawal, the enhancement of ethanol reward was likely mediated by the alleviation of acute withdrawal, i.e., negative reinforcement. Enhancement of ethanol reward during acute withdrawal may be a key component in the shift from episodic to chronic ethanol consumption that characterizes alcoholism.

  11. Semiology of hypermotor (hyperkinetic) seizures. (United States)

    Alqadi, Khalid; Sankaraneni, Ram; Thome, Ursula; Kotagal, Prakash


    Hypermotor seizures (HMSs) consist of complex movements involving proximal segments of the limbs and trunk that appear violent and inappropriate for the situation. We analyzed hypermotor seizure videos in seizure-free patients (Engel class I) following resective epilepsy surgery. After completion of video analysis, we reviewed EEG and neuroimaging data. Search of our epilepsy surgery database yielded 116 patients classified as having hypermotor seizures between 1996 and 2013. From this subset, 17/31 (55%) patients had been seizure-free for >6months (mean follow-up: 3.3years). Mean seizure duration was 35s (range: 6-91s), of which the HM phase lasted a mean of 22s (range: 3-53s). In 16 patients (95%), hypermotor activity was seen at or within 10s of clinical seizure onset. Type I semiology occurred in 6 patients, type II semiology in 10 patients, and 1 patient exhibited features of both. Type I and type II semiologies were noted in patients who had frontal lobe as well as extrafrontal resections. Nonversive head and body turning occurred in 10 patients (ranging from 90° to 270°) which was ipsilateral to the side of resection in all patients and seen both in frontal and extrafrontal resections. Six out of eleven patients with abnormal MRI and 4/6 patients with nonlesional MRI underwent invasive EEG evaluation. Eight patients (47%) had frontal lobe resection, 4/17 (23%) patients had temporal lobe resection, and one patient each had parietal lobe, insular, temporoparietooccipital, or motor sparing resection; 1 patient had functional hemispherectomy. Hypermotor semiology typically occurs at or within 10s after seizure onset. Ipsilateral head/body turning appears to be of lateralizing value whereas asymmetry of limb movement was not lateralizing. Hypermotor semiology is most often seen in frontal lobe epilepsy but may occur in seizures arising from other locations. Copyright © 2015 Elsevier Inc. All rights reserved.

  12. Autonomic epileptic seizures, autonomic effects of seizures, and SUDEP. (United States)

    Moseley, Brian; Bateman, Lisa; Millichap, John J; Wirrell, Elaine; Panayiotopoulos, Chrysostomos P


    Many generalized tonic-clonic seizures are accompanied by profound autonomic changes. However, autonomic seizures and autonomic status epilepticus can also be seen with specific electroclinical syndromes (Panayiotopoulos syndrome), etiologies, and localizations. Such autonomic symptoms may impact cardiorespiratory function. While it is likely that several factors contribute to SUDEP, further study of both ictal respiratory and cardiac changes and underlying neuroanatomical mechanisms involved in autonomic seizure semiology are likely to provide important data to improve our understanding of the pathophysiology of this devastating condition. This paper will review the association between autonomic symptoms and epileptic seizures and will highlight the work of three young investigators. Drs. Lisa Bateman and Brian Moseley will review their work on cardiorespiratory effects of recorded seizures and how this assists in our understanding of SUDEP. Dr. John Millichap will review autonomic seizures and autonomic dysfunctions related to childhood epilepsy and will discuss the importance of expanded research efforts in this field.

  13. Tramadole withdrawal in a neonate: a case report

    Directory of Open Access Journals (Sweden)

    Borna H


    Full Text Available Background: Tramadol is a synthetics 4-phenyl-piperidine analogue of codeine used for treating moderate to severe pain. Tramadol is a FDA pregnancy category C medication which induces release of serotonin and inhibits the reuptake of norepinephrine. Chronic use of this drug during pregnancy may lead to physical dependency and withdrawal syndrome in the neonate.Case presentation: We report the newborn of a woman admitted in the delivery ward of Mostafa Khomeini Hospital in Tehran, Iran in 2011. The mother suffered from chronic low back pain and headache and frequently took tramadol during pregnancy. The infant had a gestational age of 38.5 w, a birth weight of 2950 gr and an Apgar score of 9/10 at 1 and 5 minutes after birth. The first signs of withdrawal syndrome occurred after 24 h with nausea, vomiting, poor feeding, and tremor. Later, agitation, tremor, hyprertonicity, and repeated multifocal myoclonus, and generalized tonic-clonic seizures developed. Clinical signs of withdrawal syndrome waned under phenobarbital therapy.Conclusion: Drug withdrawal syndrome should be considered in the neonates of pregnant mothers who chronically take tramadol. Tramadol administration during pregnancy should be restricted to carefully selected cases.

  14. Self-treatment of opioid withdrawal using kratom (Mitragynia speciosa korth). (United States)

    Boyer, Edward W; Babu, Kavita M; Adkins, Jessica E; McCurdy, Christopher R; Halpern, John H


    Kratom (Mitragynia speciosa korth) is recognized increasingly as a remedy for opioid withdrawal by individuals who self-treat chronic pain. A patient who had abruptly ceased injection hydromorphone abuse self-managed opioid withdrawal and chronic pain using kratom. After co-administering the herb with modafinil he experienced a tonic-clonic seizure, but he reported only modest abstinence once kratom administration stopped. We confirmed the identity of the plant matter he ingested as kratom and identified no contaminants or adulterants. We also conducted high-throughput molecular screening and the binding affinity at mu, delta and kappa receptors of mitragynine. We report the self-treatment of chronic pain and opioid withdrawal with kratom. The predominant alkaloid of kratom, mitragynine, binds mu- and kappa-opioid receptors, but has additional receptor affinities that might augment its effectiveness at mitigating opioid withdrawal. The natural history of kratom use, including its clinical pharmacology and toxicology, are poorly understood.

  15. A case of rhabdomyolysis associated with severe opioid withdrawal. (United States)

    Gangahar, Deepali


    While the risk of opioid overdose is widely accepted, the dangers of opioid withdrawal are far less clearly defined. The purpose of this publication is to provide evidence against the erroneous clinical dictum that opioid withdrawal is never life-threatening. This case report (N = 1) illustrates an unfortunate, common scenario of a man abusing prescription opioids and heroin. His attempt at self-detoxification with buprenorphine-naloxone resulted in life-threatening opioid withdrawal. A detailed account of each day of his withdrawal period was documented by patient and family report and review of all medical records. The patient was contacted three months after hospitalization to verify information and determine progress in treatment and abstinence from drugs and alcohol. A review of the literature was completed on severe cases of precipitated and spontaneous opioid withdrawal followed by a discussion of the significance as it relates to this case. Given the widespread use of prescription opioids and opioid maintenance treatment, physicians should be aware of the complications of acute opioid withdrawal and should be equipped to treat these complications. © American Academy of Addiction Psychiatry.

  16. Transient pseudohypoparathyroidism and neonatal seizure. (United States)

    Manzar, S


    The case of a neonate is presented who had late onset seizure associated with hypocalcemia, hyperphosphatemia, and raised parathyroid hormone. The infant did not have any stigmata of pseudohypoparathyroidism. The hypocalcemia was initially resistant to calcium therapy, but responded to vitamin D analog therapy. The diagnosis of 'transient neonatal pseudohypoparathyroidism' was entertained, as the infant remained stable and seizure-free with normal serum biochemistry during 8 months of follow-up.

  17. Management Of Post Stroke Seizures

    Directory of Open Access Journals (Sweden)

    Kavian Ghandehari


    Full Text Available The incidence of seizures in relation to stroke is 8.9%, with a frequency of 10.6 and 8.6% in haemorrhagic and ischaemic stroke, respectively. In subarachnoid haemorrhage the incidence is 8.5%. Due to the fact that infarcts are significantly more frequent than haemorrhages, seizures are mainly related to occlusive vascular disease of the brain. The general view is to consider stroke-related seizures as harmless complications in the course of a prolonged vascular disease involving the heart and brain. Seizures can be classified as those of early and those of late onset in a paradigm comparable to post-traumatic epilepsy, with an arbitrary dividing point of two weeks after the event. Most early-onset seizures occur during the first day after the stroke. Late-onset seizures occur three times more often than early-onset ones. A first late-onset epileptic event is most likely to take place between six months and two years after the stroke. However, up to 28% of patients develop their first seizure several years later. Simple partial seizures, with or without secondary generalisation, account for about 50% of total seizures, while complex partial spells, with or without secondary generalisation, and primary generalised tonic–clonic insults account for approximately 25% each. Status epilepticus occurs in 12% of stroke patients, but the recurrence rate after an initial status epilepticus is not higher than after a single seizure. Inhibitory seizures, mimicking transient ischaemic attacks, are observed in 7.1% of cases. The only clinical predictor of late-onset seizures is the initial presentation of partial anterior circulation syndrome due to a territorial infarct. Patients with total anterior circulation syndrome have less chance of developing epileptic spells, not only due to their shorter life expectancy but also due to the fact that the large infarcts are sharply demarcated in these patients. The optimal timing and type of antiepileptic drug

  19. Kratom, an Emerging Drug of Abuse: A Case Report of Overdose and Management of Withdrawal. (United States)

    Diep, Jack; Chin, David Tian; Gupta, Somdatta; Syed, Faraz; Xiong, Ming; Cheng, Jianguo


    Kratom is an herb indigenous to Southeast Asia with psychoactive opioid compounds, often used as a treatment for chronic pain or opiate withdrawal symptoms. It is legally and readily available via Internet sales and has been identified as an emerging drug of abuse in the United States. Kratom use has been associated with psychosis, seizures, and even death. At lower doses, kratom acts as a stimulant, while at higher doses, it produces analgesia and euphoria. Here, we describe the successful management of kratom overdose and withdrawal in a young man with negative toxicology screens.

  20. Molecular mechanisms of synaptic remodeling in alcoholism. (United States)

    Kyzar, Evan J; Pandey, Subhash C


    Alcohol use and alcohol addiction represent dysfunctional brain circuits resulting from neuroadaptive changes during protracted alcohol exposure and its withdrawal. Alcohol exerts a potent effect on synaptic plasticity and dendritic spine formation in specific brain regions, providing a neuroanatomical substrate for the pathophysiology of alcoholism. Epigenetics has recently emerged as a critical regulator of gene expression and synaptic plasticity-related events in the brain. Alcohol exposure and withdrawal induce changes in crucial epigenetic processes in the emotional brain circuitry (amygdala) that may be relevant to the negative affective state defined as the "dark side" of addiction. Here, we review the literature concerning synaptic plasticity and epigenetics, with a particular focus on molecular events related to dendritic remodeling during alcohol abuse and alcoholism. Targeting epigenetic processes that modulate synaptic plasticity may yield novel treatments for alcoholism. Published by Elsevier Ireland Ltd.

  1. Recent developments in our understanding of the semiology and treatment of psychogenic nonepileptic seizures. (United States)

    Goldstein, Laura H; Mellers, John D C


    Psychogenic nonepileptic seizures (PNES) pose clinical challenges in terms of diagnosis and management. Recent studies have thrown further light on the extent to which features of PNES semiology may distinguish PNES patients from those with epilepsy. Management of this patient group will include discussion of the diagnosis, withdrawal of antiepileptic drugs, and psychological intervention when PNES persist. However, the evidence base for these different stages remains limited, although recent studies are beginning to provide guidance for clinicians and future research.

  2. Afghanistan after NATO Withdrawal

    Directory of Open Access Journals (Sweden)

    Bojor Laviniu


    Full Text Available The conclusion of a conflict, called by some American analysts as “America’s Longest War”, after the withdrawal of the majority of NATO military forces, requires a careful analysis of the conditions and security environment that ISAF mission, International Security Afghan Forces, leaves as legacy to the Afghan military forces. The transfer of authority towards a strong government, recognized by most Afghan provinces, and benefiting from the support of national military forces able to cope with terrorist and insurgent threats on its own, are the minimum and necessary conditions leading the country towards a stable and secure environment and towards a sustainable development. Given these realities, any approach on the consequences of the transition towards self-sustainable governance becomes interesting and timely for any military political study. These are the prospects that we propose in our paper.

    An unselected series is presented of 17 infants born to epileptic mothers and exposed to sodium valproate during pregnancy. Nine infants had minor abnormalities and of these infants five also had major malformations, described as the 'fetal valproate syndrome'. The most frequent malformation was congenital heart disease. Nine of the infants had manifestations of withdrawal, such as irritability, jitteriness, abnormalities of tone, seizures, and feeding problems. Four of these infants had an u...

  5. Explosive Blast Neuropathology and Seizures

    Directory of Open Access Journals (Sweden)

    S. Krisztian eKovacs


    Full Text Available Traumatic brain injury (TBI due to explosive blast exposure is a leading combat casualty. It is also implicated as a key contributor to war related mental health diseases. A clinically important consequence of all types of TBI is a high risk for development of seizures and epilepsy. Seizures have been reported in patients who have suffered blast injuries in the Global War on Terror but the exact prevalence is unknown. The occurrence of seizures supports the contention that explosive blast leads to both cellular and structural brain pathology. Unfortunately, the exact mechanism by which explosions cause brain injury is unclear, which complicates development of meaningful therapies and mitigation strategies. To help improve understanding, detailed neuropathological analysis is needed. For this, histopathological techniques are extremely valuable and indispensable. In the following we will review the pathological results, including those from immunohistochemical and special staining approaches, from recent preclinical explosive blast studies.

  6. Intraoperative seizures during craniotomy under general anesthesia. (United States)

    Howe, John; Lu, Xiaoying; Thompson, Zoe; Peterson, Gordon W; Losey, Travis E


    An acute symptomatic seizure is a clinical seizure occurring at the time of or in close temporal association with a brain insult. We report an acute symptomatic seizure occurring during a surgical procedure in a patient who did not have a prior history of epilepsy and who did not have a lesion associated with an increased risk of epilepsy. To characterize the incidence and clinical features of intraoperative seizures during craniotomy under general anesthesia, we reviewed cases where continuous EEG was acquired during craniotomy. Records of 400 consecutive cases with propofol as general anesthesia during craniotomy were reviewed. Demographic data, indication for surgery, clinical history, history of prior seizures, duration of surgery and duration of burst suppression were recorded. Cases where seizures were observed were analyzed in detail. Two out of 400 patients experienced intraoperative seizures, including one patient who appeared to have an acute symptomatic seizure related to the surgical procedure itself and a second patient who experienced two seizures likely related to an underlying diagnosis of epilepsy. This is the first report of an acute symptomatic seizure secondary to a neurosurgical procedure. Overall, 0.5% of patients monitored experienced seizures, indicating that intraoperative seizures are rare, and EEG monitoring during craniotomies is of low yield in detecting seizures.

  7. Varying seizure semiology according to age. (United States)

    Nordli, Douglas R


    The clinical manifestations of seizures change in a predictable fashion with advancing age. For focal seizures these changes can be summarized into domains similar to those used in developmental models. These include fine motor, communication, and gross motor manifestations. Instead of socialization the fourth domain for seizure semiology concerns synchronization. Focal seizures in the very young tend to be simpler with fewer fine motor manifestations. Auras are uncommon, even in young children with some linguistic skill and it is often difficult to discern alteration of consciousness. Infantile focal seizures can present with spasms or even diffuse tonic seizures. In terms of synchronization, orderly secondary generalization is rarely seen so that primary generalized clonic seizures are rarely recorded in infants. Amongst so-called "generalized" seizures spasms are most often seen in the first year of life. Absence seizures, myoclonic-astatic and generalized tonic-clonic seizures are all usually not seen until after age 2 years. A full description of the clinical details of seizures is probably the most important part of the epilepsy history. A detailed knowledge of seizure semiology can make the history more effective and also in the identification of the correct seizure classification. Copyright © 2013 Elsevier B.V.

  8. Control rod withdrawal monitoring device

    International Nuclear Information System (INIS)

    Ebisuya, Mitsuo.


    Purpose: To prevent the power ramp even if a plurality of control rods are subjected to withdrawal operation at a time, by reducing the reactivity applied to the reactor. Constitution: The control rod withdrawal monitoring device is adapted to monitor and control the withdrawal of the control rods depending on the reactor power and the monitoring region thereof is divided into a control rod group monitoring region a transition region and a control group monitoring not interfere region. In a case if the distance between a plurality of control rods for which the withdrawal positions are selected is less than a limiting value, the coordinate for the control rods, distance between the control rods and that the control rod distance is shorter are displayed on a display panel, and the withdrawal for the control rods are blocked. Accordingly, even if a plurality of control rods are subjected successively to the withdrawal operation contrary to the control rod withdrawal sequence upon high power operation of the reactor, the power ramp can be prevented.

  10. Seizures in the life and works of Edgar Allan Poe. (United States)

    Bazil, C W


    Edgar Allan Poe, one of the most celebrated of American storytellers, lived through and wrote descriptions of episodic unconsciousness, confusion, and paranoia. These symptoms have been attributed to alcohol or drug abuse but also could represent complex partial seizures, prolonged postictal states, or postictal psychosis. Complex partial seizures were not well described in Poe's time, which could explain a misdiagnosis. Alternatively, he may have suffered from complex partial epilepsy that was complicated or caused by substance abuse. Even today, persons who have epilepsy are mistaken for substance abusers and occasionally are arrested during postictal confusional states. Poe was able to use creative genius and experiences from illness to create memorable tales and poignant poems.

  15. Opioid Withdrawal Presenting as Delirium and Role of Buprenorphine: A Case Series. (United States)

    Das, Sourav; Sah, Divyashree; Nandi, Shiladitya; Das, Payel


    Opioid withdrawal is very rarely characterized by delirium unlike alcohol or benzodiazepine withdrawal. PubMed search through October 2016 reveals only two case series on delirium as feature of withdrawal in opioid dependence syndrome. We report two cases of opioid withdrawal (heroin) presenting with delirium when low-dose buprenorphine (2 mg/day) was added. Both the cases had no other substance abuse history and nil contributory past and family history. Both of them were improved after increasing the buprenorphine dosage to 6-8 mg/day. The possibility of delirium as a part of withdrawal symptom or as a phenomenon induced by buprenorphine or due to impurities in the heroin used is discussed.

  16. Trial of Cannabidiol for Drug-Resistant Seizures in the Dravet Syndrome. (United States)

    Devinsky, Orrin; Cross, J Helen; Laux, Linda; Marsh, Eric; Miller, Ian; Nabbout, Rima; Scheffer, Ingrid E; Thiele, Elizabeth A; Wright, Stephen


    The Dravet syndrome is a complex childhood epilepsy disorder that is associated with drug-resistant seizures and a high mortality rate. We studied cannabidiol for the treatment of drug-resistant seizures in the Dravet syndrome. In this double-blind, placebo-controlled trial, we randomly assigned 120 children and young adults with the Dravet syndrome and drug-resistant seizures to receive either cannabidiol oral solution at a dose of 20 mg per kilogram of body weight per day or placebo, in addition to standard antiepileptic treatment. The primary end point was the change in convulsive-seizure frequency over a 14-week treatment period, as compared with a 4-week baseline period. The median frequency of convulsive seizures per month decreased from 12.4 to 5.9 with cannabidiol, as compared with a decrease from 14.9 to 14.1 with placebo (adjusted median difference between the cannabidiol group and the placebo group in change in seizure frequency, -22.8 percentage points; 95% confidence interval [CI], -41.1 to -5.4; P=0.01). The percentage of patients who had at least a 50% reduction in convulsive-seizure frequency was 43% with cannabidiol and 27% with placebo (odds ratio, 2.00; 95% CI, 0.93 to 4.30; P=0.08). The patient's overall condition improved by at least one category on the seven-category Caregiver Global Impression of Change scale in 62% of the cannabidiol group as compared with 34% of the placebo group (P=0.02). The frequency of total seizures of all types was significantly reduced with cannabidiol (P=0.03), but there was no significant reduction in nonconvulsive seizures. The percentage of patients who became seizure-free was 5% with cannabidiol and 0% with placebo (P=0.08). Adverse events that occurred more frequently in the cannabidiol group than in the placebo group included diarrhea, vomiting, fatigue, pyrexia, somnolence, and abnormal results on liver-function tests. There were more withdrawals from the trial in the cannabidiol group. Among patients with

    Bárbara Werner Griciunas


    Full Text Available Case report of patient who has been an alcoholic for 40 years and, after reducing alcohol intake, developed auditory and visual hallucinations, which caused behavior change. Neurological issues, electrolyte disturbances and other organ dysfunctions were excluded as cause of said change. After intake of haloperidol and risperidone, the patient had regression of symptoms and denied having presented hallucinatory symptoms. The Manual Diagnóstico e Estatístico de Transtornos Mentais – 5ª edição (DSM-V includes alcoholic hallucinosis in the Substance-Induced Psychotic Disorder (alcohol, beginning during abstinence; however, the document is not yet very well accepted among the medical community. The difficulty of the team to confirm the diagnosis of alcoholic hallucinosis lies in the differential diagnosis, as Delirium tremens and severe withdrawal syndrome with psychotic symptoms. Thus, psychopathological differentiation is important, as well as continuity of research and collaboration of other clinical teams in the evaluation.

  18. Binge drinking during pregnancy and risk of seizures in childhood: a study based on the Danish National Birth Cohort

    Sun, Yuelian; Strandberg-Larsen, Katrine; Vestergaard, Mogens


    Seizures are often found in children with fetal alcohol syndrome, but it is not known whether binge drinking during pregnancy by nonalcoholic women is associated with an increased risk of seizure disorders in children. The authors conducted a population-based cohort study of 80,526 liveborn......, and febrile seizures was retrieved from the Danish National Hospital Register. Results showed that exposure to binge drinking episodes during pregnancy was not associated with an increased risk of seizure disorders in children, except for those exposed at 11-16 gestational weeks.

  19. Neural substrates of opiate withdrawal. (United States)

    Koob, G F; Maldonado, R; Stinus, L


    Drug withdrawal is an integral part of most types of dependence and, to a large extent, opiate withdrawal has been considered the prototypic, classic measure of opiate dependence. The opiate withdrawal syndrome is characterized by multiple behavioral and physiological signs such as behavioral activation, ptosis, diarrhea, 'wet dog' shakes and motivational dysfunction, which may be represented in the CNS at multiple sites. It seems that the activating effects associated with the opiate withdrawal syndrome may be mediated by the nucleus locus coeruleus. Other signs such as wet dog shakes may involve sites in the hypothalamus important for temperature regulation. Certain other signs such as diarrhea and lacrimation may be dependent on peripheral opiate receptors. The motivational aspects of opiate withdrawal as demonstrated by the aversive stimulus effects or negative reinforcing effects (e.g. disrupted lever-pressing for food and place aversions) may involve those elements of the nucleus accumbens that are known to be important for the acute reinforcing effects of opiates in nondependent rats. Evidence exists at the cellular and molecular level for both 'within-system' and 'between-system' adaptations to dependence. Elucidation of the neural networks, cellular mechanisms and molecular elements involved in opiate withdrawal may provide not only a model for our understanding of the adaptive processes associated with drug dependence but also of those associated with other chronic insults to CNS function.

  1. Pretreatment seizure semiology in childhood absence epilepsy. (United States)

    To determine seizure semiology in children with newly diagnosed childhood absence epilepsy and to evaluate associations with short-term treatment outcomes. For participants enrolled in a multicenter, randomized, double-blind, comparative-effectiveness trial, semiologic features of pretreatment seizures were analyzed as predictors of treatment outcome at the week 16 to 20 visit. Video of 1,932 electrographic absence seizures from 416 participants was evaluated. Median seizure duration was 10.2 seconds; median time between electrographic seizure onset and clinical manifestation onset was 1.5 seconds. For individual seizures and by participant, the most common semiology features were pause/stare (seizure 95.5%, participant 99.3%), motor automatisms (60.6%, 86.1%), and eye involvement (54.9%, 76.5%). The interrater agreement for motor automatisms and eye involvement was good (72%-84%). Variability of semiology features between seizures even within participants was high. Clustering analyses revealed 4 patterns (involving the presence/absence of eye involvement and motor automatisms superimposed on the nearly ubiquitous pause/stare). Most participants experienced more than one seizure cluster pattern. No individual semiologic feature was individually predictive of short-term outcome. Seizure freedom was half as likely in participants with one or more seizure having the pattern of eye involvement without motor automatisms than in participants without this pattern. Almost all absence seizures are characterized by a pause in activity or staring, but rarely is this the only feature. Semiologic features tend to cluster, resulting in identifiable absence seizure subtypes with significant intraparticipant seizure phenomenologic heterogeneity. One seizure subtype, pause/stare and eye involvement but no motor automatisms, is specifically associated with a worse treatment outcome. © 2017 American Academy of Neurology.

  3. Alterations of rat corticostriatal synaptic plasticity after chronic ethanol exposure and withdrawal. (United States)

    Xia, Jian Xun; Li, Jing; Zhou, Rong; Zhang, Xiao Hu; Ge, Yin Bing; Ru Yuan, Xiao


    The purpose of this study was to investigate the effects of chronic ethanol exposure (CEE) and withdrawal on corticostriatal plasticity in rats. We established an animal model of alcoholism using the method of Turchan et al. (1999). A synaptic model of long-term memory (long-term depression, LTD) was used as an index and the striatum, which is related to habit learning, was selected as a target region in the present study. The effects of CEE and withdrawal on the LTD were studied in striatal slices of ethanol-dependent rats using the extracellular recording method. A stable LTD can be induced after high-frequency stimulation (HFS) in the slices of control rats. Chronic ethanol exposure and withdrawal suppressed the induction of corticostriatal LTD to different extents, with the strongest suppressive effects on LTD occurring in the slices of rats exposed to ethanol for 10 days and in those withdrawn from ethanol for 1 day. Notably, 3 days of withdrawal resulted in the shift of corticostriatal synaptic plasticity from LTD to long-term potentiation, and the peak latencies of the population spikes were obviously shortened compared with those of control rats. After 7 days of withdrawal, ethanol's effects tended to disappear. These results suggest that the alterations of corticostriatal synaptic plasticity produced by CEE and withdrawal may play a prominent role in alcohol abuse and alcoholism.

  4. The influence of a chronic adolescent nicotine exposure on ethanol withdrawal severity during adulthood in C3H mice. (United States)

    Riley, Hugh H; Zalud, André W; Diaz-Granados, Jaime L


    Animal and human studies have shown tolerance, consumption, relapse, and behavioral interactions between ethanol and nicotine, but little is understood about their interaction, especially as it relates to ethanol withdrawal in adulthood for subjects who have an adolescent history of using these drugs. This study investigated nicotine's influence on ethanol withdrawal seizures in two different age groups of male C3H mice. Adolescent and adult male C3H mice, beginning at postnatal day 28 or 70, respectively, were subjected to a 7-day chronic exposure to ethanol only, ethanol plus nicotine, nicotine only, or vehicle treatment. Six weeks later, all the groups were subjected to chronic exposure to ethanol vapors and the severity of their ethanol withdrawal seizures was assessed by handling-induced convulsions. An adolescent exposure to chronic nicotine resulted in an exacerbation of ethanol withdrawal seizures in adulthood. Given this, adolescence may contain a neurophysiological critical period that is sensitive to nicotine and which may result in an altered response to ethanol dependency in adulthood. These findings have serious implications for the long-term consequences following co-abuse of these drugs during adolescence. 2010 Elsevier Inc. All rights reserved.

  5. Alcohol abuse and related disorders treatment of alcohol dependence

    Directory of Open Access Journals (Sweden)

    Yu. P. Sivolap


    Full Text Available Alcohol abuse and alcoholism are the leading causes of worse health and increased mortality rates. Excessive alcohol consumption is the third leading cause of the global burden of diseases and a leading factor for lower lifespan and higher mortality. Alcohol abuse decreases working capacity and efficiency and requires the increased cost of the treatment of alcohol-induced disorders, which entails serious economic losses. The unfavorable medical and social consequences of excessive alcohol use determine the importance of effective treatment for alcoholism. The goals of rational pharmacotherapy of alcohol dependence are to enhance GABA neurotransmission, to suppress glutamate neurotransmission, to act on serotonin neurotransmission, to correct water-electrolyte balance, and to compensate for thiamine deficiency. Alcoholism treatment consists of two steps: 1 the prevention and treatment of alcohol withdrawal syndrome and its complications (withdrawal convulsions and delirium alcoholicum; 2 antirecurrent (maintenance therapy. Benzodiazepines are the drugs of choice in alleviating alcohol withdrawal and preventing its convulsive attacks and delirium alcoholicum. Diazepam and chlordiazepoxide are most commonly used for this purpose; the safer drugs oxazepam and lorazepam are given to the elderly and patients with severe liver lesions. Anticonvulsants having normothymic properties, such as carbamazepine, valproic acid, topiramate, and lamotrigine, are a definite alternative to benzodiazepines. The traditional Russian clinical practice (clearance detoxification has not a scientific base or significant impact on alcohol withdrawal-related states in addicts. Relapse prevention and maintenance therapy for alcohol dependence are performed using disulfiram, acamprosate, and naltrexone; since 2013 the European Union member countries have been using, besides these agents, nalmefene that is being registered in Russia.

  6. Awake seizures after pure sleep-related epilepsy: a systematic review and implications for driving law. (United States)

    Thomas, R H; King, W H; Johnston, J A; Smith, P E M


    Who with sleep seizures is safe to drive? Driving law is controversial; ineligibility varies between individual US states and EU countries. Current UK driving law is strongly influenced by a single-centre study from 1974 where most participants were not taking antiepileptic drugs (AEDs). However, pure sleep-related epilepsy is often fully controlled on medication, and its withdrawal can provoke awake seizures. This systematic review asked, 'What is the risk of awake seizures in pure sleep-related epilepsy?' 9885 titles were identified; 2312 were excluded (not human or adult); 40 full texts were reviewed; six papers met our inclusion criteria; each of these six studies had a different pure sleep-related epilepsy definition. Using the largest prospective study, we were able to calculate next year's awake seizure chance (treated with antiepileptic medication). This was maximal in the second year: 5.7% (95% CI 3.0 to 10.4%). European licensing bodies including the UK's Driver and Vehicle Licensing Agency broadly accept a risk of less than 20% for Group 1 licensing. However, this study excluded patients with frontal-lobe epilepsies. Furthermore, follow-up (n=160) varied from 2 to 6 years, yet new awake seizures may occur even after 10-20 years of pure sleep-related epilepsy A paucity of evidence underpins present licensing law; current rulings would be difficult to defend if legally challenged. The law may be penalising people with pure sleep-related epilepsy without increased risk of awake seizures, while failing to identify subgroups at unacceptable risk of an awake seizure at the wheel.

  7. Nonlinear analysis of EEG for epileptic seizures

    Energy Technology Data Exchange (ETDEWEB)

    Hively, L.M.; Clapp, N.E.; Daw, C.S.; Lawkins, W.F. [Oak Ridge National Lab., TN (United States); Eisenstadt, M.L. [Knoxville Neurology Clinic, St. Mary`s Medical Center, Knoxville, TN (United States)


    We apply chaotic time series analysis (CTSA) to human electroencephalogram (EEG) data. Three epoches were examined: epileptic seizure, non-seizure, and transition from non-seizure to seizure. The CTSA tools were applied to four forms of these data: raw EEG data (e-data), artifact data (f-data) via application of a quadratic zero-phase filter of the raw data, artifact-filtered data (g- data) and that was the residual after subtracting f-data from e-data, and a low-pass-filtered version (h-data) of g-data. Two different seizures were analyzed for the same patient. Several nonlinear measures uniquely indicate an epileptic seizure in both cases, including an abrupt decrease in the time per wave cycle in f-data, an abrupt increase in the Kolmogorov entropy and in the correlation dimension for e-h data, and an abrupt increase in the correlation dimension for e-h data. The transition from normal to seizure state also is characterized by distinctly different trends in the nonlinear measures for each seizure and may be potential seizure predictors for this patient. Surrogate analysis of e-data shows that statistically significant nonlinear structure is present during the non-seizure, transition , and seizure epoches.

    Full Text Available The article is devoted to rare and unique type of epileptic seizures – inhibitory motor seizures, characterized by the inability to execute a voluntary movement with preserved consciousness. The exact prevalence of this type of seizures is not known, but many cases are unrecognized or non-correctly diagnosed as Todd's paralysis. Therefore practical doctors should know the clinical and electroencephalographic characteristics of this type of seizures andtake them into account in the differential diagnoses . The authors presented a detailed review of the literature, including the historical data, etiology, pathogenesis and proposed mechanisms of formation of inhibitory motor seizures, clinical and EEG characteristics, therapeutic approaches. Antiepileptic drugs of choice used in the treatment of inhibitory motor seizures are valproic acid (preferably depakine chronosphere – original prolonged form of valproate. The authors also presented their observations of patients with inhibitory motor seizures.

  9. Treatment of refractory neonatal seizures with topiramate. (United States)

    Riesgo, Rudimar; Winckler, Maria Isabel; Ohlweiler, Lygia; Ranzan, Josiane; Becker, Michele; Salvador, Socrates; Magalhaes, Luiza; Ribeiro, Ricardo


    The objective of this study is to describe the usefulness of topiramate in refractory neonatal seizures. We reported the clinical off-label use of topiramate in three cases of refractory neonatal seizures of unclear origin with no response to conventional antiepileptic drugs. In all cases, the seizures were completely controlled with adding topiramate. All patients became seizure free during hospitalization and were followed by approximately 1 year after hospital discharge, with monotherapy with topiramate. The clinical off-label use of topiramate in neonatal seizures is still incipient. When searching publications in this matter, only one report was identified. Because of its efficacy for both seizures and neuroprotection, topiramate could be a useful choice in refractory neonatal seizures.

  10. Electroencephalography after a single unprovoked seizure. (United States)

    Debicki, Derek B


    Electroencephalography (EEG) is an essential diagnostic tool in the evaluation of seizure disorders. In particular, EEG is used as an additional investigation for a single unprovoked seizure. Epileptiform abnormalities are related to seizure disorders and have been shown to predict recurrent unprovoked seizures (i.e., a clinical definition of epilepsy). Thus, the identification of epileptiform abnormalities after a single unprovoked seizure can inform treatment options. The current review addresses the relationship between EEG abnormalities and seizure recurrence. This review also addresses factors that are found to improve the yield of recording epileptiform abnormalities including timing of EEG relative to the new-onset seizure, use of repeat studies, use of sleep deprivation and prolonged recordings.

    The aim of this study was to clarify characteristics of post-encephalopathic epilepsy (PEE) in children after acute encephalopathy with biphasic seizures and late reduced diffusion (AESD), paying particular attention to precise diagnosis of seizure types. Among 262 children with acute encephalopathy/encephalitis registered in a database of the Tokai Pediatric Neurology Society between 2005 and 2012, 44 were diagnosed with AESD according to the clinical course and magnetic resonance imaging (MRI) findings and were included in this study. Medical records were reviewed to investigate clinical data, MRI findings, neurologic outcomes, and presence or absence of PEE. Seizure types of PEE were determined by both clinical observation by pediatric neurologists and ictal video-electroencephalography (EEG) recordings. Of the 44 patients after AESD, 10 (23%) had PEE. The period between the onset of encephalopathy and PEE ranged from 2 to 39 months (median 8.5 months). Cognitive impairment was more severe in patients with PEE than in those without. Biphasic seizures and status epilepticus during the acute phase of encephalopathy did not influence the risk of PEE. The most common seizure type of PEE on clinical observation was focal seizures (n = 5), followed by epileptic spasms (n = 4), myoclonic seizures (n = 3), and tonic seizures (n = 2). In six patients with PEE, seizures were induced by sudden unexpected sounds. Seizure types confirmed by ictal video-EEG recordings were epileptic spasms and focal seizures with frontal onset, and all focal seizures were startle seizures induced by sudden acoustic stimulation. Intractable daily seizures remain in six patients with PEE. We demonstrate seizure characteristics of PEE in children after AESD. Epileptic spasms and startle focal seizures are common seizure types. The specific seizure types may be determined by the pattern of diffuse subcortical white matter injury in AESD and age-dependent reorganization of the brain

  12. Vaccination, seizures and 'vaccine damage'. (United States)

    Brown, Natasha J; Berkovic, Samuel F; Scheffer, Ingrid E


    Concerns about the safety of vaccination have plagued the community, with reduction in vaccine uptake resulting in increased risk of epidemics. Vaccination has been implicated in the cause of febrile seizures, 'vaccine encephalopathy' and autistic spectrum disorders. Evaluation of alleged associations is complicated by evolution in the vaccination field. This review focuses on the risk of seizures following vaccination and the alleged associations of vaccination with vaccine encephalopathy and also with autism spectrum disorders. Over the last decade the introduction of new vaccines such as the acellular pertussis vaccine has produced a reduction in seizures following vaccination, the outcome of which was benign even with older vaccines. New evidence emerged in 2006 showing that cases of alleged 'vaccine encephalopathy' are due to mutations within a sodium channel gene. The weight of epidemiological evidence does not support a relationship between vaccination and childhood epileptic encephalopathies or autism spectrum disorders. Vaccines are safer than ever before, but the challenge remains to convey this message to society in such a way that produces change in attitudes to vaccination and subsequent increase in vaccine coverage.

  13. Smartphone applications for seizure management. (United States)

    Pandher, Puneet Singh; Bhullar, Karamdeep Kaur


    Technological advancements continue to provide innovative ways of enhancing patient care in medicine. In particular, the growing popularity of smartphone technology has seen the recent emergence of a myriad of healthcare applications (or apps) that promise to help shape the way in which health information is delivered to people worldwide. While limited research already exists on a range of such apps, our study is the first to examine the salient features of smartphone applications as they apply to the area of seizure management. For the purposes of this review, we conducted a search of the official online application stores of the five major smartphone platforms: iPhone, Android, Blackberry, Windows Mobile and Nokia-Symbian. Apps were included if they reported to contain some information or tools relating to seizure management and excluded if they were aimed exclusively at health professionals. A total of 28 applications met these criteria. Overall, we found an increasing number of epilepsy apps available on the smartphone market, but with only a minority offering comprehensive educational information alongside tools such as seizure diaries, medication tracking and/or video recording. © The Author(s) 2014.

  14. Reward, addiction, withdrawal to nicotine. (United States)

    De Biasi, Mariella; Dani, John A


    Nicotine is the principal addictive component that drives continued tobacco use despite users' knowledge of the harmful consequences. The initiation of addiction involves the mesocorticolimbic dopamine system, which contributes to the processing of rewarding sensory stimuli during the overall shaping of successful behaviors. Acting mainly through nicotinic receptors containing the α4 and β2 subunits, often in combination with the α6 subunit, nicotine increases the firing rate and the phasic bursts by midbrain dopamine neurons. Neuroadaptations arise during chronic exposure to nicotine, producing an altered brain condition that requires the continued presence of nicotine to be maintained. When nicotine is removed, a withdrawal syndrome develops. The expression of somatic withdrawal symptoms depends mainly on the α5, α2, and β4 (and likely α3) nicotinic subunits involving the epithalamic habenular complex and its targets. Thus, nicotine taps into diverse neural systems and an array of nicotinic acetylcholine receptor (nAChR) subtypes to influence reward, addiction, and withdrawal.

  17. Marked Seizure Reduction after MCT Supplementation

    Directory of Open Access Journals (Sweden)

    Raed Azzam


    Full Text Available We report the case of a 43-year-old man with history of nonsurgical partial epilepsy who previously failed multiple trials of antiepileptic drugs. Medium-chain triglycerides (MCT were added to his regular diet in the form of pure oil. Subsequently, his seizure frequency was markedly reduced from multiple daily seizures to one seizure every four days. His seizures recurred after transient discontinuation of MCT over a period of ten days. His seizure improvement was achieved at a dose of four tablespoons of MCT twice daily with no reported side effects. He developed significant diarrhea and flatulence at higher doses. We conclude that MCT oil supplementation to regular diet may provide better seizure control in some patients. MCT oil supplementation may be a more tolerable alternative to the standard ketogenic diet.

  18. Role of neuroimaging in first seizure diagnosis. (United States)

    Crocker, Candice E; Pohlmann-Eden, Bernhard; Schmidt, Matthias H


    The primary goal of neuroimaging in a first, unprovoked seizure is to identify a lesion that can explain the seizure. Secondarily, neuroimaging may be used to predict seizure recurrence and assist with the diagnosis of epilepsy. However, the events leading from a first seizure to epilepsy, with or without an identifiable epileptogenic lesion, are not well understood, and it is not always clear which lesions are epileptogenic as opposed to incidental. Much neuroimaging research to date has focused on findings in chronic epilepsy, rather than first seizure. Dedicated epilepsy imaging with high quality MRI protocols maximizes the likelihood of a diagnosis. However, a significant proportion of patients are MRI-negative, prompting researchers in the field to continue the search for better imaging strategies. Here we describe the role of neuroimaging in the assessment of a first seizure, the current state of the art and possible future directions. Copyright © 2016 British Epilepsy Association.

  20. Breakthrough seizures after starting vilazodone for depression. (United States)

    McKean, James; Watts, Hannah; Mokszycki, Robert


    Vilazodone is a new selective serotonin reuptake inhibitor (SSRI) and serotonin 5-HT1a partial agonist that is approved by the United States Food and Drug Administration to treat major depression. SSRI-induced seizures are rare and are more likely to be associated with larger doses and severe symptoms such as those present in serotonin syndrome. Several case reports have implicated SSRIs, buspirone, or the combination of these agents as the cause of seizures, but these reports were confounded with either coingestions or doses that exceeded FDA recommendations. We describe a 22-year-old woman with a history of seizure disorder who had been seizure free for the previous 8 years and experienced two breakthrough seizures shortly after starting vilazodone. Her dose of vilazodone had recently been titrated to 40 mg/day when she experienced the first seizure. She was instructed to taper vilazodone over the next several days, then discontinue the drug, and then follow up with her neurologist. Based on the patient's history, physical examination, and recent dose increase, it was plausible that vilazodone was the cause of the seizures. Use of the Naranjo adverse drug reaction probability scale indicated a possible relationship (score of 4) between her development of seizures and vilazodone therapy. The pharmacodynamics of this particular class of SSRI has both proconvulsive and anticonvulsive mechanisms. This is of particular concern in patients with a history of seizure disorder who are starting antidepressive therapy. In persons with epilepsy who are taking vilazodone and experience breakthrough seizures, practitioners should consider this drug as a potential cause of these seizures. Thus, until future research and experience with vilazodone can provide a definitive answer, clinicians should be cautious when prescribing this medication to treat depression in patients with a history of seizure disorder. © 2015 Pharmacotherapy Publications, Inc.

  1. Water withdrawals in Florida, 2012 (United States)

    Marella, Richard L.


    In 2012, the total amount of water withdrawn in Florida was estimated to be 14,237 million gallons per day (Mgal/d). Saline water accounted for 7,855 Mgal/d (55 percent), and freshwater accounted for 6,383 Mgal/d (45 percent). Groundwater accounted for 4,167 Mgal/d (65 percent) of freshwater withdrawals, and surface water accounted for the remaining 2,216 Mgal/d (35 percent). Surface water accounted for nearly all (99.9 percent) saline-water withdrawals. Freshwater withdrawals were greatest in Palm Beach County (682 Mgal/d), and saline-water withdrawals were greatest in Pasco County (1,822 Mgal/d). Fresh groundwater provided drinking water (through either public supply or private domestic wells) for 17.699 million residents (93 percent of Florida’s population), and fresh surface water provided drinking water for 1.375 million residents (7 percent). The statewide public-supply gross per capita water use for 2012 was estimated at 136 gallons per day.

  2. Molecular basis of alcoholism. (United States)

    Most, Dana; Ferguson, Laura; Harris, R Adron


    Acute alcohol intoxication causes cellular changes in the brain that last for hours, while chronic alcohol use induces widespread neuroadaptations in the nervous system that can last a lifetime. Chronic alcohol use and the progression into dependence involve the remodeling of synapses caused by changes in gene expression produced by alcohol. The progression of alcohol use, abuse, and dependence can be divided into stages, which include intoxication, withdrawal, and craving. Each stage is associated with specific changes in gene expression, cellular function, brain circuits, and ultimately behavior. What are the molecular mechanisms underlying the transition from recreational use (acute) to dependence (chronic)? What cellular adaptations result in drug memory retention, leading to the persistence of addictive behaviors, even after prolonged drug abstinence? Research into the neurobiology of alcoholism aims to answer these questions. This chapter will describe the molecular adaptations caused by alcohol use and dependence, and will outline key neurochemical participants in alcoholism at the molecular level, which are also potential targets for therapy. © 2014 Elsevier B.V.

  4. Deep Recurrent Neural Networks for seizure detection and early seizure detection systems

    Energy Technology Data Exchange (ETDEWEB)

    Talathi, S. S. [Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)


    Epilepsy is common neurological diseases, affecting about 0.6-0.8 % of world population. Epileptic patients suffer from chronic unprovoked seizures, which can result in broad spectrum of debilitating medical and social consequences. Since seizures, in general, occur infrequently and are unpredictable, automated seizure detection systems are recommended to screen for seizures during long-term electroencephalogram (EEG) recordings. In addition, systems for early seizure detection can lead to the development of new types of intervention systems that are designed to control or shorten the duration of seizure events. In this article, we investigate the utility of recurrent neural networks (RNNs) in designing seizure detection and early seizure detection systems. We propose a deep learning framework via the use of Gated Recurrent Unit (GRU) RNNs for seizure detection. We use publicly available data in order to evaluate our method and demonstrate very promising evaluation results with overall accuracy close to 100 %. We also systematically investigate the application of our method for early seizure warning systems. Our method can detect about 98% of seizure events within the first 5 seconds of the overall epileptic seizure duration.

  5. Buprenorphine for managing opioid withdrawal. (United States)

    Gowing, Linda; Ali, Robert; White, Jason M; Mbewe, Dalitso


    Managed withdrawal is a necessary step prior to drug-free treatment or as the endpoint of substitution treatment. To assess the effects of buprenorphine versus tapered doses of methadone, alpha 2 -adrenergic agonists, symptomatic medications or placebo, or different buprenorphine regimens for managing opioid withdrawal, in terms of the intensity of the withdrawal syndrome experienced, duration and completion of treatment, and adverse effects. We searched the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 11, 2016), MEDLINE (1946 to December week 1, 2016), Embase (to 22 December 2016), PsycINFO (1806 to December week 3, 2016), and the Web of Science (to 22 December 2016) and handsearched the reference lists of articles. Randomised controlled trials of interventions using buprenorphine to modify the signs and symptoms of withdrawal in participants who were primarily opioid dependent. Comparison interventions involved reducing doses of methadone, alpha 2 -adrenergic agonists (clonidine or lofexidine), symptomatic medications or placebo, and different buprenorphine-based regimens. We used standard methodological procedures expected by Cochrane. We included 27 studies involving 3048 participants. The main comparators were clonidine or lofexidine (14 studies). Six studies compared buprenorphine versus methadone, and seven compared different rates of buprenorphine dose reduction. We assessed 12 studies as being at high risk of bias in at least one of seven domains of methodological quality. Six of these studies compared buprenorphine with clonidine or lofexidine and two with methadone; the other four studies compared different rates of buprenorphine dose reduction.For the comparison of buprenorphine and methadone in tapered doses, meta-analysis was not possible for the outcomes of intensity of withdrawal or adverse effects. However, information reported by the individual studies was suggestive of buprenorphine and methadone having similar capacity to

    Energy Technology Data Exchange (ETDEWEB)

    Theodore, W.H.; Fishbein, D.; Deitz, M.; Baldwin, P.


    We used positron emission tomography (PET) with (/sup 18/F)2-deoxyglucose to study cerebellar glucose metabolism (LCMRglu) and the effect of phenytoin (PHT) in 42 patients with complex partial seizures (CPS), and 12 normal controls. Mean +/- SD patient LCMRglu was 6.9 +/- 1.8 mg glucose/100 g/min (left = right), significantly lower than control values of 8.5 +/- 1.8 (left, p less than 0.006), and 8.3 +/- 1.6 (right, p less than 0.02). Only four patients had cerebellar atrophy on CT/MRI; cerebellar LCMRglu in these was 5.5 +/- 1.5 (p = 0.054 vs. total patient sample). Patients with unilateral temporal hypometabolism or EEG foci did not have lateralized cerebellar hypometabolism. Patients receiving phenytoin (PHT) at the time of scan and patients with less than 5 years total PHT exposure had lower LCMRglu, but the differences were not significant. There were weak inverse correlations between PHT level and cerebellar LCMRglu in patients receiving PHT (r = -0.36; 0.05 less than p less than 0.1), as well as between length of illness and LCMRglu (r = -0.22; 0.05 less than p less than 0.1). Patients with complex partial seizures have cerebellar hypometabolism that is bilateral and due only in part to the effect of PHT.

  10. De novo psychogenic seizures after epilepsy surgery: case report

    Directory of Open Access Journals (Sweden)



    Full Text Available The occurrence of de novo psychogenic seizures after epilepsy surgery is rare, and is estimated in 1.8% to 3.6%. Seizures after epilepsy surgery should be carefully evaluated, and de novo psychogenic seizures should be considered especially when there is a change in the ictal semiology. We report a patient with de novo psychogenic seizures after anterior temporal lobe removal for refractory temporal lobe epilepsy. Once psychogenic seizures were diagnosed and psychiatric treatment was started, seizures stopped.

  11. Can developmental venous anomalies cause seizures? (United States)

    Dussaule, Claire; Masnou, Pascal; Nasser, Ghaïdaa; Archambaud, Frédérique; Cauquil-Michon, Cécile; Gagnepain, Jean-Paul; Bouilleret, Viviane; Denier, Christian


    Developmental venous anomalies (DVAs) are congenital anatomical variants of normal venous drainage of normal brain. Although DVAs are often discovered on the occasion of a seizure, their involvement in epilepsy is poorly studied. Our objective was to determine whether DVA can cause seizures, in the cases where there is no associated lesion, including no cavernoma or dysplasia. Based on clinical history, cerebral MRI, EEG recording, and 18 F-FDG PET, we report 4 patients with DVA revealed by seizures. The first patient had a convulsive seizure caused by a hemorrhagic infarction due to thrombosis of her DVA. The second patient had a left temporo-parietal DVA next to a nonspecific lesion, possibly a sequelae of a venous infarction. The last two patients disclosed an isolated and uncomplicated DVA with a concordant epileptic focus confirmed on ictal video EEG recording. We reviewed literature and identified 21 other published cases of seizures caused by complications of a DVA and 9 patients that may have a direct link between epilepsy and an isolated and uncomplicated DVA. Seizures are linked to a DVA in two main situations: presence of an associated epileptogenic lesion, such as cavernoma or dysplasia, and occurrence of a complication of the DVA. Before concluding that a seizure is caused by a DVA, it is essential to perform full MRI protocols to search them. It remains rare and uncertain that isolated and uncomplicated DVA can cause seizures. In this last situation, physiopathological processes are probably different in each patient.

  19. Seizure phenotypes, periodicity, and sleep-wake pattern of seizures in Kcna-1 null mice. (United States)

    Wright, Samantha; Wallace, Eli; Hwang, Youngdeok; Maganti, Rama


    This study was undertaken to describe seizure phenotypes, natural progression, sleep-wake patterns, as well as periodicity of seizures in Kcna-1 null mutant mice. These mice were implanted with epidural electroencephalography (EEG) and electromyography (EMG) electrodes, and simultaneous video-EEG recordings were obtained while animals were individually housed under either diurnal (LD) condition or constant darkness (DD) over ten days of recording. The video-EEG data were analyzed to identify electrographic and behavioral phenotypes and natural progression and to examine the periodicity of seizures. Sleep-wake patterns were analyzed to understand the distribution and onset of seizures across the sleep-wake cycle. Four electrographically and behaviorally distinct seizure types were observed. Regardless of lighting condition that animals were housed in, Kcna-1 null mice initially expressed only a few of the most severe seizure types that progressively increased in frequency and decreased in seizure severity. In addition, a circadian periodicity was noted, with seizures peaking in the first 12h of the Zeitgeber time (ZT) cycle, regardless of lighting conditions. Interestingly, seizure onset differed between lighting conditions where more seizures arose out of sleep in LD conditions, whereas under DD conditions, the majority occurred out of the wakeful state. We suggest that this model be used to understand the circadian pattern of seizures as well as the pathophysiological implications of sleep and circadian disturbances in limbic epilepsies.

  20. Do recurrent seizure-related head injuries affect seizures in people with epilepsy? (United States)

    Friedman, David E.; Chiang, Sharon; Tobias, Ronnie S.


    Seizure-related head injuries (SRHIs) are among the most commonly encountered injuries in people with epilepsy (PWE). Whether head injury has an effect on preexisting epilepsy is not known. The purpose of this study was to systematically assess for any possible effects of SRHIs on seizure frequency and seizure semiology over a 2-year period. We identified 204 patients who have been followed at the Baylor Comprehensive Epilepsy Center from 2008 to 2010. SRHI occurred in 18.1% of the cohort. Most injuries (91%) were classified as mild. Though seizure frequency varied following head injury, overall seizure frequency was not significantly impacted by presence or absence of SRHI over the 2-year study period. Changes in seizure semiology were not observed in those with SRHIs. Although mild SRHI is common among PWE, it does not appear to have an effect on seizure characteristics over a relatively short period. PMID:22227592

  1. Febrile seizures and risk of schizophrenia

    BACKGROUND: Febrile seizure is a benign condition for most children, but experiments in animals and neuroimaging studies in humans suggest that some febrile seizures may damage the hippocampus, a brain area of possible importance in schizophrenia. METHODS: A population-based cohort of all children...... with schizophrenia. A history of febrile seizures was associated with a 44% increased risk of schizophrenia [relative risk (RR)=1.44; 95% confidence interval (CI), 1.07-1.95] after adjusting for confounding factors. The association between febrile seizures and schizophrenia remained virtually unchanged when...... restricting the analyses to people with no history of epilepsy. A history of both febrile seizures and epilepsy was associated with a 204% increased risk of schizophrenia (RR=3.04; 95% CI, 1.36-6.79) as compared with people with no such history. CONCLUSIONS: We found a slightly increased risk of schizophrenia...

  2. Seizure detection algorithms based on EMG signals

    DEFF Research Database (Denmark)

    Conradsen, Isa

    Background: the currently used non-invasive seizure detection methods are not reliable. Muscle fibers are directly connected to the nerves, whereby electric signals are generated during activity. Therefore, an alarm system on electromyography (EMG) signals is a theoretical possibility. Objective......: to show whether medical signal processing of EMG data is feasible for detection of epileptic seizures. Methods: EMG signals during generalised seizures were recorded from 3 patients (with 20 seizures in total). Two possible medical signal processing algorithms were tested. The first algorithm was based...... the frequency-based algorithm was efficient for detecting the seizures in the third patient. Conclusion: Our results suggest that EMG signals could be used to develop an automatic seizuredetection system. However, different patients might require different types of algorithms /approaches....

  3. Source and sink nodes in absence seizures. (United States)

    Rodrigues, Abner C; Machado, Birajara S; Caboclo, Luis Otavio S F; Fujita, Andre; Baccala, Luiz A; Sameshima, Koichi


    As opposed to focal epilepsy, absence seizures do not exhibit a clear seizure onset zone or focus since its ictal activity rapidly engages both brain hemispheres. Yet recent graph theoretical analysis applied to absence seizures EEG suggests the cortical focal presence, an unexpected feature for this type of epilepsy. In this study, we explore the characteristics of absence seizure by classifying the nodes as to their source/sink natures via weighted directed graph analysis based on connectivity direction and strength estimation using information partial directed coherence (iPDC). By segmenting the EEG signals into relatively short 5-sec-long time windows we studied the evolution of coupling strengths from both sink and source nodes, and the network dynamics of absence seizures in eight patients.

    Cerebrovascular disease is the leading cause of epilepsy in adults, although post-stroke seizures reported frequency is variable and few studies used EEG in their identification. To describe and compare EEG and clinical epileptic manifestations frequency in patients with an anterior circulation ischaemic stroke. Prospective study of acute anterior circulation ischaemic stroke patients, consecutively admitted to a Stroke Unit over 24 months and followed-up for 1 year. All patients underwent standardized clinical and diagnostic assessment. Seizure occurrence was clinically evaluated during hospitalization and by a telephone interview at 6 months and a clinical appointment at 12 months after stroke. Video-EEG was performed in the first 72 h (1st EEG), daily after the 1st EEG for the first 7 days after the stroke, or later if neurological worsening, at discharge, and at 12 months. 151 patients were included (112 men) with a mean age of 67.4 (11.9) years. In the 1st year after stroke, 38 patients (25.2%) had an epileptic seizure. During hospitalization, 27 patients (17.9%) had epileptiform activity (interictal or ictal) in the EEG, 7 (25.9%) of them electrographic seizures. During the first week after stroke, 22 (14.6%) patients had a seizure and 4 (2.6%) non-convulsive status epilepticus criteria. Five (22.7%) acute symptomatic seizures were exclusively electrographic. At least one remote symptomatic seizure occurred in 23 (16%) patients. In the first 7 days after stroke, more than one-fifth of patients with seizures had exclusively electrographic seizures. Without a systematic neurophysiological evaluation the frequency of post-stroke seizures are clinically underestimated.

  5. Clinical features of poststroke epileptic seizures

    Directory of Open Access Journals (Sweden)

    T. V. Danilova


    Full Text Available Poststroke epileptic seizures are detected in 30–40% of patients over 60 years of age. Objective: to explore the clinical features of epileptic seizures in stroke, risk factors for their development to form the bases for prediction and elaboration of optimal therapy. Patients and methods. 468 patients with ischemic stroke were examined. A study group included 265 patients (176 men and 89 women aged 31–89 years with epileptic seizures; a control group comprised 203 non-epileptic patients (126 men and 77 women aged 31–91 years. The patients of both groups were matched for age, clinical characteristics, and pathogenetic subtypes of stroke. Instrumental examinations were performed in the attack-free interval. Neurological status was evaluated using the conventional procedure (the National Institute of Health Stroke Scale; brain magnetic resonance imaging (MRI, magnetic resonance angiography, electroencephalography, extraand transcranial duplex sound of cerebral vessels, by estimating the level and degree of stenosis and cerebrovascular responsiveness. Results and discussion. Focal seizures were noted to more frequently develop with a preponderance of simple partial seizures within the first 7 days of stroke, with neurological worsening in the acute period of the disease. Stroke in the left carotid and vertebrobasilar beds may provoke the development of early seizures. The cortical localization of ischemic foci and pre-stroke chronic brain ischemia with the signs of circulatory comorbidity in the anterior and posterior circulatory systems may be a risk factor of epileptic seizures. There was an association of the type of an epileptic seizure and the size of an ischemic focus, as evidenced by MRI, with a tendency towards the generalization of seizures in the extensive ischemic foci. A tendency toward the generalization of epileptic seizures was established in the development of stroke in the left carotid bed, as well as in critical stenoses and

  7. Nonepileptic Seizures: An Updated Review (United States)

    Perez, David L.; LaFrance, W. Curt


    Psychogenic nonepileptic seizures are a Functional Neurological Disorder/ Conversion Disorder subtype, which are neurobehavioral conditions at the interface of Neurology and Psychiatry. Significant advancements over the past decade have been made in the diagnosis, management and neurobiological understanding of PNES. This article reviews published PNES research focusing on semiologic features that distinguish PNES from epileptic seizures, consensus diagnostic criteria, the intersection of PNES and other comorbidities, neurobiological studies, evidence-based treatment interventions and outcome studies. Epidemiology and health care utilization studies highlight a continued unmet medical need in the comprehensive care of PNES. Consensus guidelines for diagnostic certainty are based on clinical history, semiology of witnessed typical event(s), and EEG findings. While certain semiologic features may aid the diagnosis of PNES, the gold standard remains capturing a typical event on video electroencephalography (EEG) showing the absence of epileptiform activity with history and semiology consistent with PNES. Medical-neurologic and psychiatric comorbidities are prevalent in PNES and should be assessed in diagnostic evaluations, and integrated into treatment interventions and prognostic considerations. Several studies, including a pilot multicenter, randomized clinical trial, have now demonstrated that a cognitive behavioral therapy informed psychotherapy is an efficacious treatment for PNES, and additional efforts are necessary to evaluate the utility of pharmacologic and other psychotherapy treatments. Neuroimaging studies, while requiring replication, suggest that PNES may occur in the context of alterations within and across sensorimotor, emotion regulation/processing, cognitive control and multimodal integration brain systems. Future research could investigate similarities and differences between PNES and other somatic symptom disorders. PMID:26996600

  8. Classification of clinical semiology in epileptic seizures in neonates. (United States)

    Nagarajan, Lakshmi; Palumbo, Linda; Ghosh, Soumya


    The clinical semiology of 61 neonatal seizures with EEG correlates, in 24 babies was analysed. Most seizures (89%) had multiple features during the EEG discharge. The seizures were classified using the prominent clinical feature at onset, and all features seen during the seizure, using an extended classification scheme. Orolingual features occurred most frequently at onset (30%), whereas ocular phenomena occurred most often during the seizure (70%). Orolingual, ocular and autonomic features were seen at onset in 55% of the seizures. Seizure onsets with clonic, tonic and hypomotor features were seen in 20%, 8% and 18% respectively. Clinico-electrical correlations were as follows. The EEG discharge involved both hemispheres in 54% of all seizures, in clonic seizures this was 93%. Focal clonic seizures were associated with EEG seizure onset from the contralateral hemisphere. Majority of the clonic and hypomotor seizures had a left hemisphere ictal EEG onset. Orolingual seizures frequently started from the right hemisphere, whereas ocular and autonomic seizures arose from either hemisphere. There was no significant difference in mortality, morbidity, abnormal neuroimaging and EEG background abnormalities in babies with or without clonic seizures. This study provides insights into neuronal networks that underpin electroclinical seizures, by analysing and classifying the obvious initial clinical features and those during the seizure.

  9. Delirium and High Creatine Kinase and Myoglobin Levels Related to Synthetic Cannabinoid Withdrawal

    Directory of Open Access Journals (Sweden)

    Ahmet Bulent Yazici


    Full Text Available Synthetic cannabinoids (SCs are included in a group of drugs called new psychoactive substances. Effects of SCs on the central nervous system are similar to other cannabinoids, but 2–100 times more potent than marijuana. Thus, addiction and withdrawal symptoms are more severe than natural cannabinoids. Withdrawal symptoms of SCs were reported in the literature previously. But there is no report about SC withdrawal delirium and its treatment. Several studies reported that agonists of CB1 receptors play a role in GABA and glutamatergic neurotransmission, which is similar to the effects of alcohol on GABA and glutamatergic receptors. Previous studies on alcohol delirium cases suggested that elevated creatine kinase (CK can be a marker of progress. This study reports delirium and high serum CK levels related to SC withdrawal and offers a treatment with benzodiazepine for them. We described two cases treated in our inpatient clinic about SC withdrawal with increase of serum CK level and other laboratory parameters. One of them demonstrated delirium symptoms and the other did not with early rapid treatment.

  10. On the nature of seizure dynamics. (United States)

    Jirsa, Viktor K; Stacey, William C; Quilichini, Pascale P; Ivanov, Anton I; Bernard, Christophe


    Seizures can occur spontaneously and in a recurrent manner, which defines epilepsy; or they can be induced in a normal brain under a variety of conditions in most neuronal networks and species from flies to humans. Such universality raises the possibility that invariant properties exist that characterize seizures under different physiological and pathological conditions. Here, we analysed seizure dynamics mathematically and established a taxonomy of seizures based on first principles. For the predominant seizure class we developed a generic model called Epileptor. As an experimental model system, we used ictal-like discharges induced in vitro in mouse hippocampi. We show that only five state variables linked by integral-differential equations are sufficient to describe the onset, time course and offset of ictal-like discharges as well as their recurrence. Two state variables are responsible for generating rapid discharges (fast time scale), two for spike and wave events (intermediate time scale) and one for the control of time course, including the alternation between 'normal' and ictal periods (slow time scale). We propose that normal and ictal activities coexist: a separatrix acts as a barrier (or seizure threshold) between these states. Seizure onset is reached upon the collision of normal brain trajectories with the separatrix. We show theoretically and experimentally how a system can be pushed toward seizure under a wide variety of conditions. Within our experimental model, the onset and offset of ictal-like discharges are well-defined mathematical events: a saddle-node and homoclinic bifurcation, respectively. These bifurcations necessitate a baseline shift at onset and a logarithmic scaling of interspike intervals at offset. These predictions were not only confirmed in our in vitro experiments, but also for focal seizures recorded in different syndromes, brain regions and species (humans and zebrafish). Finally, we identified several possible biophysical

  13. [Semiology and propagation of epileptic seizures]. (United States)

    Gellner, A-K; Fritsch, B


    The evaluation of episodic seizure-like symptoms is a common challenge in the neurologist's daily routine. The clinical signs (semiology) are the most important puzzle pieces to distinguish epileptic seizures from other episodic entities. Due to the often far-reaching health and social consequences of the diagnosis of epilepsy, the early and rigorous assessment of episodic symptoms by means of the patient history is important. This assessment is based on knowledge of the association of certain semiologies with epileptic syndromes and brain regions; however, certain limitations and pitfalls have to be considered. Typical propagation pathways of seizure activity determine the serial occurrence of semiological features and provide supplementary information.

  14. Quantitative Autoradiography on [(35)S]TBPS Binding Sites of Gamma- Aminobutyric Acid(A) Receptors in Discrete Brain Regions of High- Alcohol-Drinking and Low-Alcohol- Drinking Rats Selectively Bred forHigh- and Low-Alcohol Preference. (United States)

    Hwang, B.H.; Kunkler, P.E.; Lumeng, L.


    It has been documented that ethanol can potentiate brain gamma-aminobutyric acid (GABA)ergic function, and there is a close link between the GABA(A) receptor complex and effects of ethanol, including reinforcement of alcohol which is a fundamental element of alcohol preference. However, it is unknown in what discrete brain regions GABA(A) receptors might be associated with alcohol preference. In the present study, [(35)S]t-butylbicyclophosphorothionate ([(35)S]TBPS) was used to localize GABA(A) receptors in high-alcohol-drinking (HAD) rats and low-alcohol-drinking (LAD) rats which were selectively bred for high and low alcohol preference, respectively. Initial qualitative observations indicated that [(35)S]TBPS binding sites were abundant in many brain areas including the cerebral cortex, hypothalamus and amygdala of HAD and LAD rats. Furthermore, the quantitative autoradiographic analysis revealed fewer [(35)S]TBPS binding sites of GABA(A) receptors in the amygdaloid complex, central medial thalamic nucleus, lateral hypothalamic nucleus and anterior hypothalamic nucleus of HAD rats than LAD rats. Collectively, this study has indicated that HAD rats selectively bred for high alcohol preference possess lower [(35)S]TBPS binding in the brain. Since lower TBPS binding has been proposed to reflect enhanced GABAergic function, as evidenced in rats with seizure or under alcohol withdrawal, the results from the present study suggest that HAD rats might have an enhanced GABAergic function. It is thus likely that enhanced GABAergic function in the brain might be related to high alcohol preference which is characteristic in HAD rats. In addition, the present result showing no difference of [(35)S]TBPS binding in the nucleus accumbens is also in agreement with a notion that [(35)S]TBPS binding may represent only a small spectrum of the GABA(A) receptor complex which is constituted of a sophisticated subunit combination whose functional compositions are still unknown.

  16. Seizure semiology identifies patients with bilateral temporal lobe epilepsy. (United States)

    Loesch, Anna Mira; Feddersen, Berend; Tezer, F Irsel; Hartl, Elisabeth; Rémi, Jan; Vollmar, Christian; Noachtar, Soheyl


    Laterality in temporal lobe epilepsy is usually defined by EEG and imaging results. We investigated whether the analysis of seizure semiology including lateralizing seizure phenomena identifies bilateral independent temporal lobe seizure onset. We investigated the seizure semiology in 17 patients in whom invasive EEG-video-monitoring documented bilateral temporal seizure onset. The results were compared to 20 left and 20 right consecutive temporal lobe epilepsy (TLE) patients who were seizure free after anterior temporal lobe resection. The seizure semiology was analyzed using the semiological seizure classification with particular emphasis on the sequence of seizure phenomena over time and lateralizing seizure phenomena. Statistical analysis included chi-square test or Fisher's exact test. Bitemporal lobe epilepsy patients had more frequently different seizure semiology (100% vs. 40%; psemiology for the identification of bilateral TLE was high (100%) with a specificity of 60%. Lateralizing seizure phenomena had a low sensitivity (59%) but a high specificity (89%). The combination of lateralizing seizure phenomena and different seizure semiology showed a high specificity (94%) but a low sensitivity (59%). The analysis of seizure semiology including lateralizing seizure phenomena adds important clinical information to identify patients with bilateral TLE. Copyright © 2014 Elsevier B.V.

  18. EEG analysis of seizure patterns using visibility graphs for detection of generalized seizures. (United States)

    Wang, Lei; Long, Xi; Arends, Johan B A M; Aarts, Ronald M


    The traditional EEG features in the time and frequency domain show limited seizure detection performance in the epileptic population with intellectual disability (ID). In addition, the influence of EEG seizure patterns on detection performance was less studied. A single-channel EEG signal can be mapped into visibility graphs (VGS), including basic visibility graph (VG), horizontal VG (HVG), and difference VG (DVG). These graphs were used to characterize different EEG seizure patterns. To demonstrate its effectiveness in identifying EEG seizure patterns and detecting generalized seizures, EEG recordings of 615h on one EEG channel from 29 epileptic patients with ID were analyzed. A novel feature set with discriminative power for seizure detection was obtained by using the VGS method. The degree distributions (DDs) of DVG can clearly distinguish EEG of each seizure pattern. The degree entropy and power-law degree power in DVG were proposed here for the first time, and they show significant difference between seizure and non-seizure EEG. The connecting structure measured by HVG can better distinguish seizure EEG from background than those by VG and DVG. A traditional EEG feature set based on frequency analysis was used here as a benchmark feature set. With a support vector machine (SVM) classifier, the seizure detection performance of the benchmark feature set (sensitivity of 24%, FD t /h of 1.8s) can be improved by combining our proposed VGS features extracted from one EEG channel (sensitivity of 38%, FD t /h of 1.4s). The proposed VGS-based features can help improve seizure detection for ID patients. Copyright © 2017 Elsevier B.V. All rights reserved.

    Background Previous laboratory-based research suggests that withdrawal from marijuana may cause increased aggression. It is unclear whether this finding extends beyond the laboratory setting to the general population of marijuana users. The purpose of this study was to test a cross-sectional association between marijuana withdrawal symptoms and aggression among a representative sample of U.S. adult marijuana users, and to test whether this association was moderated by previous history of aggression. Methods Data were analyzed from the National Epidemiologic Survey on Alcohol and Related Conditions. Wave Two data (2004–2005) were used for all variables except for history of aggression, which was assessed during the Wave One interview (2001–2002). Two outcomes were examined: self-report general aggression and relationship aggression. Odds ratios for aggression based on withdrawal symptoms and the interaction between withdrawal symptoms and history of aggression were calculated using logistic regression, adjusting for covariates and accounting for the complex survey design. Results Among marijuana users with a history of aggression, marijuana withdrawal was associated with approximately 60% higher odds of past year relationship aggression (p aggression among those without a history of aggression, and no association with general aggression regardless of history of aggression. Conclusions The findings from this study support the notion that laboratory-based increases in aggression due to marijuana withdrawal extend to the general population of marijuana users who have a previous history of aggression.

    Agibalova, T V; Petrosian, T R; Kuznetsov, A G; Gurevich, G L; Shuvalov, S A


    This article presents the results of a study of clinical features of the development and course of alcohol dependence in patients with posttraumatic stress disorder (PTSD) in comparison with alcohol-dependent patients without PTSD. The highly progressive course, continuous alcohol consumption, high alcohol tolerance, rapidly emerged altered forms of alcohol intoxication, alcohol amnesias, alcohol withdrawal with the prevalence of psychopathological component, and more pronounced social and somatic consequences of alcohol abuse were characteristic of the PTSD group. At the same time, the alcohol-dependent patients with PTSD had the best outcome to the end of 12-month treatment with intramuscular injections of vivitrol.

  1. Counselling adults who experience a first seizure. (United States)

    Legg, Karen T; Newton, Mark


    A first seizure can result in significant uncertainty, fear and apprehension. One of the key roles of the clinician in the setting of first seizure is to provide accurate, timely information and counselling. We review the numerous components to be considered when counselling an adult patient after a first seizure. We provide a framework and manner to provide that counselling. We focus on an individualized approach and provide recommendations and information on issues of diagnosis, etiology, prognosis, the role and importance of medical testing, lifestyle considerations, driving, medication and other key counselling considerations. Accurate, timely counselling can allay fears and anxieties, remove misconceptions and reduce the risk for injury in seizure recurrence. Copyright © 2016 British Epilepsy Association.

    Fukujima, M M; Cardeal, J O; Lima, J G


    Preditive clinical factors for epileptic seizures after ischemic stroke. Clinical features of 35 patients with ischemic stroke who developed epilepsy (Group 1) were compared with those of 35 patients with ischemic stroke without epilepsy (Group 2). The age of the patients did not differ between the groups. There were more men than women and more white than other races in both groups. Diabetes melitus, hypertension, transient ischemic attack, previous stroke, migraine, Chagas disease, cerebral embolism of cardiac origin and use of oral contraceptive did not differ between the groups. Smokers and alcohol users were more frequent in Group 1 (p < 0.05). Most patients of Group 1 presented with hemiparesis; none presented cerebellar or brainstem involvement. Perhaps strokes in smokers have some different aspects, that let them more epileptogenic than in non smokers.

    To assess seizure frequency in a large French cohort of autosomal dominant early-onset Alzheimer disease (ADEOAD) and to determine possible correlations with causative mutations. A national multicentric study was performed in patients with ADEOAD harboring a pathogenic mutation within PSEN1, PSEN2, APP, or a duplication of APP, and a minimal follow-up of 5 years. Clinical, EEG, and imaging data were systematically recorded. We included 132 patients from 77 families: 94 PSEN1 mutation carriers (MCs), 16 APP duplication carriers, 15 APP MCs, and 7 PSEN2 MCs. Seizure frequency was 47.7% after a mean follow-up of 8.4 years (range 5-25). After 5-year follow-up and using a Cox model analysis, the percentages of patients with seizures were respectively 19.1% (10.8%-26.7%) for PSEN1, 28.6% (0%-55.3%) for PSEN2, 31.2% (4.3%-50.6%) for APP duplications, and no patient for APP mutation. APP duplication carriers showed a significantly increased seizure risk compared to both APP MCs (hazard ratio [HR] = 5.55 [95% confidence interval 1.87-16.44]) and PSEN1 MCs (HR = 4.46 [2.11-9.44]). Among all PSEN1 mutations, those within the domains of protein hydrophilic I, transmembrane II (TM-II), TM-III, TM-IV, and TM-VII were associated with a significant increase in seizure frequency compared to other domains (HR = 4.53 [1.93-10.65], p = 0.0005). Seizures are a common feature of ADEOAD. In this population, risk was significantly higher in the APP duplication group than in all other groups. Within PSEN1, 5 specific domains were associated with a higher seizure risk indicating specific correlations between causative mutation and seizures. © 2016 American Academy of Neurology.

  10. Ketogenic diet: Predictors of seizure control (United States)

    Agarwal, Nitin; Arkilo, Dimitrios; Farooq, Osman; Gillogly, Cynthia; Kavak, Katelyn S; Weinstock, Arie


    Background: The ketogenic diet is an effective non-pharmacologic treatment for medically resistant epilepsy. The aim of this study was to identify any predictors that may influence the response of ketogenic diet. Methods: A retrospective chart review for all patients with medically resistant epilepsy was performed at a tertiary care epilepsy center from 1996 to 2012. Patient- and diet-related variables were evaluated with respect to seizure reduction at 1, 3, 6, 9 and 12-month intervals and divided into four possible outcome classes. Results: Sixty-three patients met inclusion. Thirty-seven (59%) reported >50% seizure reduction at 3 months with 44% and 37% patients benefiting at 6-month and 12-month follow up, respectively. A trend toward significant seizure improvement was noted in 48% patients with seizure onset >1 year at 12-month (p = 0.09) interval and in 62% patients with >10 seizure/day at 6-month interval (p = 0.054). An ordinal logistic regression showed later age of seizure to have higher odds of favorable response at 1-month (p = 0.005) and 3-month (p = 0.013) follow up. Patients with non-fasting diet induction were more likely to have a favorable outcome at 6 months (p = 0.008) as do females (p = 0.037) and those treated with higher fat ratio diet (p = 0.034). Conclusion: Our study reports the effectiveness of ketogenic diet in children with medically resistant epilepsy. Later age of seizure onset, female gender, higher ketogenic diet ratio and non-fasting induction were associated with better odds of improved seizure outcome. A larger cohort is required to confirm these findings. PMID:28620490

    Based on improvement in our understanding of the prognosis of young adults with new onset seizures, and cumulative experience with the rules in effect for the last 30 years, a substantial change in the regulations affecting the fitness and profiling of these soldiers has been made. In general, these liberalize retention and profiling, set limits on the duration of trials of duty, provide for fitness determinations in soldiers with pseudo-seizures, and specify when neurologic consultation is required.

  13. Infantile Spasms: Little Seizures, BIG Consequences (United States)

    Shields, W Donald


    Infantile spasms is one of the “catastrophic childhood epilepsies” because of the difficulty in controlling seizures and the association with mental retardation. However, early recognition, a careful diagnostic evaluation, and proper treatment may allow some children to attain seizure control and to achieve a normal, or at least much improved, level of development. Thus, there is the opportunity to have an important impact in the lives of these unfortunate children and their families. PMID:16761063

  14. Predictors of acute symptomatic seizures after intracranial hemorrhage in infants. (United States)

    Bansal, Seema; Kebede, Tewodros; Dean, Nathan P; Carpenter, Jessica L


    To determine the prevalence of acute symptomatic seizures in infants with supratentorial intracranial hemorrhage, to identify potential risk factors, and to determine the effect of acute seizures on long-term morbidity and mortality. Children less than 24 months with intracranial hemorrhage were identified from a neurocritical care database. All patients who received seizure prophylaxis beginning at admission were included in the study. Risk factors studied were gender, etiology, location of hemorrhage, seizure(s) on presentation, and the presence of parenchymal injury. Acute clinical and electrographic seizures were identified from hospital medical records. Subsequent development of late seizures was determined based on clinical information from patients' latest follow-up. Patients with idiopathic neonatal intracranial hemorrhage, premature infants, and those with prior history of seizures were excluded from analysis. Seventy-two infants met inclusion criteria. None. Forty percent of infants had acute symptomatic seizures. The prevalence was similar regardless of whether etiology of hemorrhage was traumatic or nontraumatic. Seizures on presentation and parenchymal injury were independent risk factors of acute seizures (p = 0.001 and p = 0.006, respectively). Younger children and women were also at higher risk (p Acute seizures were not predictive of mortality, but nearly twice as many patients with acute seizures developed late seizures when compared with those without. Electrographic seizures and parenchymal injury were also predictive of development of late seizures (p hemorrhage are at high risk for acute symptomatic seizures. This is regardless of the etiology of hemorrhage. Younger patients, women, patients with parenchymal injury, and patients presenting with seizure are most likely to develop acute seizures. Although the benefits of seizure prophylaxis have not been studied in this specific population, these results suggest that it is an important component

  15. Intravenous Carbamazepine for Adults With Seizures. (United States)

    Vickery, P Brittany; Tillery, Erika E; DeFalco, Alicia Potter


    To review the pharmacology, pharmacokinetics, efficacy, safety, dosage and administration, potential drug-drug interactions, and place in therapy of the intravenous (IV) formulation of carbamazepine (Carnexiv) for the treatment of seizures in adult patients. A comprehensive PubMed and EBSCOhost search (1945 to August 2017) was performed utilizing the keywords carbamazepine, Carnexiv, carbamazepine intravenous, IV carbamazepine, seizures, epilepsy, and seizure disorder. Additional data were obtained from literature review citations, manufacturer's product labeling, and Lundbeck website as well as and governmental sources. All English-language trials evaluating IV carbamazepine were analyzed for this review. IV carbamazepine is FDA approved as temporary replacement therapy for treatment of adult seizures. Based on a phase I trial and pooled data from 2 open-label bioavailability studies comparing oral with IV dosing, there was no noted indication of loss of seizure control in patients switched to short-term replacement antiepileptic drug therapy with IV carbamazepine. The recommended dose of IV carbamazepine is 70% of the patient's oral dose, given every 6 hours via 30-minute infusions. The adverse effect profile of IV carbamazepine is similar to that of the oral formulation, with the exception of added infusion-site reactions. IV carbamazepine is a reasonable option for adults with generalized tonic-clonic or focal seizures, previously stabilized on oral carbamazepine, who are unable to tolerate oral medications for up to 7 days. Unknown acquisition cost and lack of availability in the United States limit its use currently.

  16. Epileptic Seizures Prediction Using Machine Learning Methods

    Directory of Open Access Journals (Sweden)

    Syed Muhammad Usman


    Full Text Available Epileptic seizures occur due to disorder in brain functionality which can affect patient’s health. Prediction of epileptic seizures before the beginning of the onset is quite useful for preventing the seizure by medication. Machine learning techniques and computational methods are used for predicting epileptic seizures from Electroencephalograms (EEG signals. However, preprocessing of EEG signals for noise removal and features extraction are two major issues that have an adverse effect on both anticipation time and true positive prediction rate. Therefore, we propose a model that provides reliable methods of both preprocessing and feature extraction. Our model predicts epileptic seizures’ sufficient time before the onset of seizure starts and provides a better true positive rate. We have applied empirical mode decomposition (EMD for preprocessing and have extracted time and frequency domain features for training a prediction model. The proposed model detects the start of the preictal state, which is the state that starts few minutes before the onset of the seizure, with a higher true positive rate compared to traditional methods, 92.23%, and maximum anticipation time of 33 minutes and average prediction time of 23.6 minutes on scalp EEG CHB-MIT dataset of 22 subjects.

  17. [Seizures in neurofibromatosis. What is the risk?]. (United States)

    Drouet, A


    The prevalence and the type of seizures associated with neurofibromatosis 1 (NF1) and 2 (NF2) are not adequately characterized. NF1 has a birth incidence of one in 2500, and NF2 one in 25000. Seizures are an occasional complication in NF1 patients and there is no data for NF2 patients. Central nervous system tumors are always suspected, since NF1 and NF2 are caused by mutations in tumor suppressor gene controlling cell proliferation and differentiation. The aim of this article is to provide a synthetic overview about epilepsy associated with NF1 and NF2 based on published studies. In NF1, the type of seizures and their response to therapy are reported, the heterogeneity of etiology is also discussed. For NF2 patients, no specific data are available; the current knowledge comes from series of NF2 patients for which seizures has revealed the disease or from isolated case reports of tumors associated with seizures. Cryptogenic epilepsy without anatomic defect is likely to be related to NF1, while seizures seem to be secondary to leptomeningeal tumors (meningioma, meningioangiomatosis) in NF2 patients.

  18. Anoxic seizures: self-terminating syncopes. (United States)

    Stephenson, J B


    This review focuses on anoxic seizures induced by self terminating syncopes in the young. Anoxic seizures are nonepileptic events consequent upon abrupt interruption of the energy supply to metabolically active cerebral neurones. Anoxic seizures are the most common paroxysmal events misdiagnosed as epilepsy. Neurally mediated syncopes have numerous appellations, especially in the young. This proliferation of terminology likely results from uncertainty regarding pathophysiology. The most important type of self-limiting syncope from the point of view of diagnostic difficulty has been called neurocardiogenic or vasovagal syncope and reflex anoxic seizure, amongst other names: this review includes a video clip of such a child with prolonged asystole. It also includes a detailed case history emphasising the feelings of a patient with this type of syncope who was misdiagnosed as having epilepsy for many years. The second class of self-terminating syncope discussed and illustrated on video is the so-called breath-holding spell of young children. The third example illustrated is the compulsive Valsalva manoeuvre of individuals with autistic spectrum disorder, in which anoxic seizures - as shown on the video clips - are easily misdiagnosed as epileptic seizures, with unfortunate consequences.

  19. Monitor for status epilepticus seizures (United States)

    Johnson, Mark; Simkins, Thomas


    This paper describes the sensor technology and associated electronics of a monitor designed to detect the onset of a seizure disorder called status epilepticus. It is a condition that affects approximately 3-5 percent of those individuals suffering from epilepsy. This form of epilepsy does not follow the typical cycle of start-peak-end. The convulsions continue until medically interrupted and are life threatening. The mortality rate is high without prompt medical treatment at a suitable facility. The paper describes the details of a monitor design that provides an inexpensive solution to the needs of those responsible for the care of individuals afflicted with this disorder. The monitor has been designed as a cooperative research and development effort involving the United States Army Armament Research, Development, and Engineering Center's Benet Laboratories (Benet) and the Cerebral Palsy Center for the Disabled (Center), in association with the Department of Neurology at Albany Medical College (AMC). Benet has delivered a working prototype of the device for field testing, in collaboration with Albany Medical College. The Center has identified several children in need of special monitoring and has agreed to pursue commercialization of the device.

    Full Text Available The patient was a 41 year old woman that was brought to the emergency department (ED by her husband following seizure. According to the relatives accompanying her, the seizure was of tonic-clonic type, had occurred one hour before presentation to ED, and had lasted 3 minutes. The patient had been drowsy for about 15 minutes after the end of the seizure. She had no history of head trauma and did not mention headache, nausea and vomiting, fever, vision problems or others. On presentation, amnesia regarding the things that happened was evident. In her history, she had a generalized tonic-clonic seizure 4 years back, regarding which she had not done proper follow up for taking necessary diagnostic measures and had not been treated with anti-epileptic medication. She had a history of surgery for removing cold thyroid nodule 20 years ago and was under calcium treatment for 15 years but she had decided to stop taking her medications since 5 year ago. She did not have a history of alcohol or drug abuse. The patient was conscious and awake on presentation and did not have any specific clinical complaints. Her vital signs on presentation were as follows:Blood Pressure = 120/70mmHg, Pulse Rate = 68/minute, Respiratory Rate = 16/minute, O2saturation= 98% at air room, Oral Temperature= 37°C, and bedside blood sugar in the normal range.In head and neck examination, the surgery scar was seen in the thyroid region. Examination of the thyroid also showed a nodular surface in palpation. Examination of the heart, lungs, abdomen and extremities did not have pathologic findings. Neurologic examinations including evaluation of cranial nerves, sense and power of the muscles, cerebellar examination and deep tendon reflexes were normal. Based on the opinion of the in-charge physician, anti-epileptic drugs were not prescribed at this stage. Laboratory tests including complete blood cell count, liver function tests (LFT, and level of blood sugar (BS, sodium, potassium

    Full Text Available OBJECTIVES: This work speaks of a pilot test administered in four public services with emergency care (one at a hospital and three at community clinics in the city of Ribeirão Preto, São Paulo, to test an assessment protocol for Alcohol Withdrawal Syndrome. Involved were auxiliaries, technicians and soon-to-be-nurses. The object was to evaluate the protocol´s potential as a guide to nursing care, and to test whether it was adequate in terms of comprehension and applicability. METHODS: A protocol based on the Clinical Institute Withdrawal Assessment was constructed to be applied by nursing professionals in hospitals and community clinics, allowing for possible alterations based upon individual patients. Fifty-nine workers tested the protocol over four months. RESULTS: Sixty-eight patients (21 women and 47 men, with average age between 34 and 40 years, were interviewed. Alcohol was the predominant drug of use (90% on a daily average between both sexes. The protocol was designed to systematize health care. Among its purposes were: to facilitate care (42.4%; provide a script for faster orientation (30.5%; provide information giving professional updates (25.4%; provide explanations regarding the particular sickness (23.7. CONCLUSIONS: The experience was positive, identifying a lack of knowledge about Alcohol Withdrawal Syndrome. However, an interest to learn more on the subject became evident among workers.OBJETIVOS: Relatar la experiencia piloto en cuatro servicios públicos con servicios de emergencia (uno hospitalario y tres comunitarios en la ciudad de Ribeirão Preto- Sao Paulo, para probar un protocolo de evaluación del Síndrome de Abstinencia Alcohólica entre los auxiliares, técnicos y eventuales enfermeros, y evaluar el potencial del formulario como guía orientadora del cuidado de enfermería, asi como la adecuación del mismo en términos de comprensión y aplicabilidad.

  5. [Etiopathogenic elements of alcoholism]. (United States)

    Pelc, I


    Various factors contribute to a predisposition towards the excessive consumption of alcohol: socio-demographic factors, a disturbed family background or certain neurological disorders in childhood, a family background of heavy drinking or total abstinence, or a genetic predisposition towards the biochemical reactions of excessive drinking. Alcohol dependence is the last of several stages which begin with drinking on "social occasions" during adolescence or even childhood, which may lead to certain people drinking excessively in certain social surroundings; this may easily become a habit if the subject moreover suffers from psychological problems inducing him to consume greater quantities more frequently to overcome inhibitions or to escape. This increased consumption leads in turn to psychological dependence, and toxicomania becomes apparent since if drinking is suddenly stopped, giving rise to neuro-vegetative disorders, these only disappear when further alcohol is consumed. This vicious circle is completed by psychological problems affecting personal relationships and professional activities. Thus for the alcoholic, for whom at the outset drinking was usually merely a social habit, the consumption of alcohol has become an escape from the reality of his situation, often drinking solely to avoid withdrawal symptoms, and therefore the appropriate therapy in these cases is detoxication.

  6. Partial Seizures Are Associated with Early Increases in Signal Complexity (United States)

    Jouny, Christophe C; Bergey, Gregory K; Franaszczuk, Piotr J


    Objectives Partial seizures are often believed to be associated with EEG signals of low complexity because seizures are associated with increased neural network synchrony. The investigations reported here provide an assessment of the signal complexity of epileptic seizure onsets using newly developed quantitative measures. Methods Using the Gabor atom density (GAD) measure of signal complexity, 339 partial seizures in 45 patients with intracranial electrode arrays were analyzed. Segmentation procedures were applied to determine the timing and amplitude of GAD changes relative to the electrographic onset of the seizure. Results 330 out of 339 seizures have significant complexity level changes, with 319 (97%) having an increase in complexity. GAD increases occur within seconds of the onset of the partial seizure but are not observed in channels remote from the focus. The complexity increase is similar for seizures from mesial temporal origin, neocortical temporal and extra-temporal origin. Conclusions Partial onset seizures are associated with early increases in signal complexity as measured by GAD. This increase is independent of the location of the seizure focus. Significance Despite the often predominant rhythmic activity that characterizes onset and early evolution of epileptic seizures, partial seizure onset is associated with an early increase in complexity. These changes are common to partial seizures originating from different brain regions, indicating a similar seizure dynamic. PMID:19910249

  7. Clinical characteristics of seizures associated with viral gastroenteritis in children. (United States)

    Ueda, Hitoshi; Tajiri, Hitoshi; Kimura, Sadami; Etani, Yuri; Hosoi, Gaku; Maruyama, Tomoko; Noma, Haruyoshi; Kusumoto, Yoshio; Takano, Tomoko; Baba, Yoshiko; Nagai, Toshizaburo


    We analyzed the clinical features of seizures during gastroenteritis in children by comparing the norovirus and rotavirus pathogen, and the impact of fever, if present, during the seizure episodes. Retrospective analysis was performed on 293 consecutive pediatric patients admitted with viral gastroenteritis to Osaka General Hospital between November 2007 and May 2009. Eighteen patients developed seizures, 12 of whom were positive for norovirus and six for rotavirus, as revealed by antigen detection. Of these 18 seizure patients, eight presented without fever (the aFS group) and 10 presented with febrile episodes (FS group). Seizure patients in the rotavirus group (83%) were more likely to be febrile than those in the norovirus group (58%). Compared with the aFS group, 90% of patients in the FS group presented seizures at an early stage of gastroenteritis. The frequency of clustered seizures in the FS group was considerably higher than that of febrile seizures in general and was also as high as that of "convulsions with mild gastroenteritis (CwG)". All seizure patients, whether febrile or afebrile, presented with generalized tonic clonic seizures (GTCS), complex partial seizures (CPS), or both. Diazepam (DZP) was less effective and carbamazepine (CBZ) was completely effective for the cessation of seizures in the FS group, similar to the drug response observed in CwG. The causative pathogen (norovirus or rotavirus) affected the frequency of febrile episodes during gastroenteritis, but fever had little effect on the clinical features of seizures. However, seizures occurred earlier during gastroenteritis in the FS group. On the whole, the clinical features of febrile seizures during viral gastroenteritis may closely resemble those of "convulsions with mild gastroenteritis" (CwG) than those of febrile seizures in general with respect to the frequency of clustered seizures and the antiepileptic drug responses and may have a pathogenic mechanism distinct from those of

  8. Long-term seizure, cognitive, and psychiatric outcome following trans-middle temporal gyrus amygdalohippocampectomy and standard temporal lobectomy. (United States)

    Bujarski, Krzysztof A; Hirashima, Fuyuki; Roberts, David W; Jobst, Barbara C; Gilbert, Karen L; Roth, Robert M; Flashman, Laura A; McDonald, Brenna C; Saykin, Andrew J; Scott, Rod C; Dinnerstein, Eric; Preston, Julie; Williamson, Peter D; Thadani, Vijay M


    Previous comparisons of standard temporal lobectomy (STL) and selective amygdalohippocampectomy (SelAH) have been limited by inadequate long-term follow-up, variable definitions of favorable outcome, and inadequate consideration of psychiatric comorbidities. The authors performed a retrospective analysis of seizure, cognitive, and psychiatric outcomes in a noncontemporaneous cohort of 69 patients with unilateral refractory temporal lobe epilepsy and MRI evidence of mesial temporal sclerosis after either an STL or an SelAH and examined seizure, cognitive, and psychiatric outcomes. The mean duration of follow-up for STL was 9.7 years (range 1-18 years), and for trans-middle temporal gyrus SelAH (mtg-SelAH) it was 6.85 years (range 1-15 years). There was no significant difference in seizure outcome when "favorable" was defined as time to loss of Engel Class I or II status; better seizure outcome was seen in the STL group when "favorable" was defined as time to loss of Engel Class IA status (p=0.034). Further analysis revealed a higher occurrence of seizures solely during attempted medication withdrawal in the mtg-SelAH group than in the STL group (p=0.016). The authors found no significant difference in the effect of surgery type on any cognitive and most psychiatric variables. Standard temporal lobectomy was associated with significantly higher scores on assessment of postsurgical paranoia (p=0.048). Overall, few differences in seizure, cognitive, and psychiatric outcome were found between STL and mtg-SelAH on long-term follow-up. Longer exposure to medication side effects after mtg-SelAH may adversely affect quality of life but is unlikely to cause additional functional impairment. In patients with high levels of presurgical psychiatric disease, mtg-SelAH may be the preferred surgery type.

  9. Serial postoperative awake and sleep EEG and long-term seizure outcome after anterior temporal lobectomy for hippocampal sclerosis. (United States)

    Di Gennaro, Giancarlo; Casciato, Sara; D'Aniello, Alfredo; De Risi, Marco; Quarato, Pier Paolo; Mascia, Addolorata; Grammaldo, Liliana G; Meldolesi, Giulio N; Esposito, Vincenzo; Picardi, Angelo


    To test if postoperative prolonged awake and sleep EEG monitoring predict long-term seizure outcome in patients operated for drug-resistant temporal lobe epilepsy due to hippocampal sclerosis (TLE-HS). This longitudinal study includes 107 patients with MTLE-HS who underwent anterior temporal lobectomy (ATL), were followed for at least 5 years (mean 8.3, range 5-12), had postoperative EEG after 2 months and at least one prolonged video-EEG monitoring during both wakefulness and sleep after 12 and 24 months. At each follow-up visit, the presence of interictal epileptiform discharges (IED) was determined, and seizure outcome was evaluated. Sixty-six patients (62%) remained free from auras and seizures throughout the follow-up period. Twenty-six (24%), 22 (21%), and 16 (16%) patients had IED at the 2-month, 12-month, and 24-month follow-up, respectively. The presence of IED at each time point was found to be associated with seizure or aura recurrence. Sleep recording contributed to the identification of patients with IED, as half of patients with IED displayed anomalies in sleep EEG only. In multivariate analysis, the presence of IED 2 months after surgery was found to be associated with seizure or aura recurrence independent of pre-operative factors consistently reported as outcome predictors in the literature. The presence of IED in serial postoperative EEG including sleep recording may predict long-term seizure outcome after ATL for TLE-HS. Serial postoperative EEGs may contribute to outcome prediction and help making decision about medication withdrawal in patients operated for TLE-HS. Copyright © 2014 Elsevier B.V.

  10. Sex Differences in Seizure Types and Symptoms (United States)

    Carlson, Chad; Dugan, Patricia; Kirsch, Heidi E; Friedman, Daniel


    Background Despite the increasing interest in sex differences in disease manifestations and responses to treatment, very few data are available on sex differences in seizure types and semiology. The Epilepsy Phenome/Genome Project (EPGP) is a large-scale, multi-institutional, collaborative study that aims to create a comprehensive repository of detailed clinical information and DNA samples from a large cohort of people with epilepsy. We used this well-characterized cohort to explore differences in seizure types as well as focal seizure symptoms between males and females. Methods We reviewed the EPGP database and identified individuals with generalized epilepsy of unknown etiology (GE) (n=760; female 446, male 314), non-acquired focal epilepsy (NAFE) (n=476; female 245, male 231), or both (n=64; female 33, male 31). Demographic data along with characterization of seizure type and focal seizure semiologies were examined. Results In GE, males reported atonic seizures more frequently than females (6.5% vs. 1.7%; p<0.001). No differences were observed in other generalized seizure types. In NAFE, no sex differences were seen for seizure types with or without alteration of consciousness or progression to secondary generalization. Autonomic (16.4% vs. 26.6%; p=0.005), psychic (26.7% vs. 40.3%; p=0.001), and visual symptoms (10.3% vs. 19.9%; p=0.002) were more frequently reported in females than males. Specifically, of psychic symptoms, more females than males endorsed déjà vu (p=0.001), but not forced thoughts, derealization/depersonalization, jamais vu, or fear. With corrections for multiple comparisons, there were no significant differences in aphasic, motor, somatosensory, gustatory, olfactory, auditory, vertiginous, or ictal headache symptoms between sexes. Conclusions Significant differences between the sexes were observed in the reporting of atonic seizures, which was more common in males with GE, and for autonomic, visual, and psychic symptoms associated with NAFE

  11. Neurobiological Basis of Alcohol Addiction

    Directory of Open Access Journals (Sweden)

    Milagros Lisset León Regal


    Full Text Available Alcoholism is a serious social problem due to its impact on individual and collective health. In order to provide an update on the latest findings that explain the development and symptoms of alcohol addiction, the short and long term changes that this disorder causes in the central nervous system are shown in this paper. A total of 52 information sources were consulted, including 43 journal articles, 4 books and statistical reports. The main network managers were used. The interaction of ethanol with various structures of the neuronal membrane affects the cytoarchitecture and brain function associated with the reward system, motor processing, learning and memory, resulting in the development of alcohol dependence. In addition, ethanol-induced changes in excitation/inhibition explain the phenomena of alcohol tolerance and withdrawal.

  12. Protracted ethanol withdrawal in rats: Tolerance to the anxiolytic effects of diazepam and pentobarbital but not phenobarbital

    Energy Technology Data Exchange (ETDEWEB)

    Lai, H.; Prather, P.L. (Texas Coll. of Osteopathic Medicine, Fort Worth (United States))


    Anxiety is a common symptom during ethanol withdrawal contributing to its continuous abuse and alcoholism. Ethanol withdrawal in rats produces an interoceptive discriminative stimulus (IDS) similar to that produced by the anxiogenic drug pentylenetetrazol (PTZ). This stimulus peaks at 12 hours after last dose of ethanol and thereafter the IDS is detected for several days (protracted withdrawal) by sensitization to a probe drug. previously, the authors have shown that during the protracted withdrawal, the IDS is enhanced by GABA receptor antagonists suggesting alteration of brain GABA systems. This report provides further evidence that chronic ethanol alters GABAergic systems. Rats were trained to discriminate PTZ (20 mg/kg, ip) from saline. Diazepam, pentobarbital and phenobarbital blocked the PTZ-IDS dose dependently. Ethanol, 4.5% w/v, was then given in a nutritionally complete diet for a week. On termination of the ethanol diet, rats exhibited signs and symptoms of withdrawal which returned to baseline within 3 days. During the protracted withdrawal period, the authors then redetermined the blockade of the PTZ-IDS. Significant tolerance was observed to the effectiveness of diazepam and pentobarbital, but not to phenobarbital. Since diazepam and pentobarbital produce significantly more enhancement of GABAergic activity than does phenobarbital, these data further suggest alteration of brain GABAergic systems during protracted withdrawal from ethanol.

  15. Are seizures in the setting of sleep deprivation provoked? (United States)

    Lawn, Nicholas; Lieblich, Sam; Lee, Judy; Dunne, John


    It is generally accepted that sleep deprivation contributes to seizures. However, it is unclear whether a seizure occurring in the setting of sleep deprivation should be considered as provoked or not and whether this is influenced by seizure type and etiology. This information may have an important impact on epilepsy diagnosis and management. We prospectively analyzed the influence of sleep deprivation on the risk of seizure recurrence in patients with first-ever unprovoked seizures and compared the findings with patients with first-ever provoked seizures. Of 1026 patients with first-ever unprovoked seizures, 204 (20%) were associated with sleep deprivation. While the overall likelihood of seizure recurrence was slightly lower in sleep-deprived patients with first-ever seizures (log-rank p=0.03), sleep deprivation was not an independent predictor of seizure recurrence on multivariate analysis. Seizure recurrence following a first-ever unprovoked seizure associated with sleep deprivation was far more likely than for 174 patients with a provoked first-ever seizure (log-rank psleep deprivation should not be regarded as provoked.

  16. A new model to study sleep deprivation-induced seizure. (United States)

    Lucey, Brendan P; Leahy, Averi; Rosas, Regine; Shaw, Paul J


    A relationship between sleep and seizures is well-described in both humans and rodent animal models; however, the mechanism underlying this relationship is unknown. Using Drosophila melanogaster mutants with seizure phenotypes, we demonstrate that seizure activity can be modified by sleep deprivation. Seizure activity was evaluated in an adult bang-sensitive seizure mutant, stress sensitive B (sesB(9ed4)), and in an adult temperature sensitive seizure mutant seizure (sei(ts1)) under baseline and following 12 h of sleep deprivation. The long-term effect of sleep deprivation on young, immature sesB(9ed4) flies was also assessed. Laboratory. Drosophila melanogaster. Sleep deprivation. Sleep deprivation increased seizure susceptibility in adult sesB(9ed4)/+ and sei(ts1) mutant flies. Sleep deprivation also increased seizure susceptibility when sesB was disrupted using RNAi. The effect of sleep deprivation on seizure activity was reduced when sesB(9ed4)/+ flies were given the anti-seizure drug, valproic acid. In contrast to adult flies, sleep deprivation during early fly development resulted in chronic seizure susceptibility when sesB(9ed4)/+ became adults. These findings show that Drosophila is a model organism for investigating the relationship between sleep and seizure activity. © 2015 Associated Professional Sleep Societies, LLC.

  17. Termination patterns of complex partial seizures: An intracranial EEG study. (United States)

    Afra, Pegah; Jouny, Christopher C; Bergey, Gregory K


    While seizure onset patterns have been the subject of many reports, there have been few studies of seizure termination. In this study we report the incidence of synchronous and asynchronous termination patterns of partial seizures recorded with intracranial arrays. Data were collected from patients with intractable complex partial seizures undergoing presurgical evaluations with intracranial electrodes. Patients with seizures originating from mesial temporal and neocortical regions were grouped into three groups based on patterns of seizure termination: synchronous only (So), asynchronous only (Ao), or mixed (S/A, with both synchronous and asynchronous termination patterns). 88% of the patients in the MT group had seizures with a synchronous pattern of termination exclusively (38%) or mixed (50%). 82% of the NC group had seizures with synchronous pattern of termination exclusively (52%) or mixed (30%). In the NC group, there was a significant difference of the range of seizure durations between So and Ao groups, with Ao exhibiting higher variability. Seizures with synchronous termination had low variability in both groups. Synchronous seizure termination is a common pattern for complex partials seizures of both mesial temporal or neocortical onset. This may reflect stereotyped network behavior or dynamics at the seizure focus. Copyright © 2015 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

  18. The Cannabis Withdrawal Scale development: patterns and predictors of cannabis withdrawal and distress. (United States)

    Allsop, David J; Norberg, Melissa M; Copeland, Jan; Fu, Shanlin; Budney, Alan J


    Rates of treatment seeking for cannabis are increasing, and relapse is common. Management of cannabis withdrawal is an important intervention point. No psychometrically sound measure for cannabis withdrawal exists, and as a result treatment developments cannot be optimally targeted. The aim is to develop and test the psychometrics of the Cannabis Withdrawal Scale and use it to explore predictors of cannabis withdrawal. A volunteer sample of 49 dependent cannabis users provided daily scores on the Cannabis Withdrawal Scale during a baseline week and 2 weeks of abstinence. Internal reliability (Cronbach's alpha=0.91), test-retest stability (average intra-class correlation=0.95) and content validity analysis show that the Cannabis Withdrawal Scale has excellent psychometric properties. Nightmares and/or strange dreams was the most valid item (Wald χ²=105.6, Psleep was also an intense withdrawal symptom (Wald χ²=42.31, Pcannabis withdrawal. The Cannabis Withdrawal Scale can be used as a diagnostic instrument in clinical and research settings where regular monitoring of withdrawal symptoms is required.

This study aims to quantify functional impairment to normal daily activities from cannabis withdrawal, and looks at the factors predicting functional impairment. In addition the study tests the influence of functional impairment from cannabis withdrawal on cannabis use during and after an abstinence attempt.A volunteer sample of 49 non-treatment seeking cannabis users who met DSM-IV criteria for dependence provided daily withdrawal-related functional impairment scores during a one-week baseline phase and two weeks of monitored abstinence from cannabis with a one month follow up. Functional impairment from withdrawal symptoms was strongly associated with symptom severity (p=0.0001. Participants with more severe cannabis dependence before the abstinence attempt reported greater functional impairment from cannabis withdrawal (p=0.03. Relapse to cannabis use during the abstinence period was associated with greater functional impairment from a subset of withdrawal symptoms in high dependence users. Higher levels of functional impairment during the abstinence attempt predicted higher levels of cannabis use at one month follow up (p=0.001.Cannabis withdrawal is clinically significant because it is associated with functional impairment to normal daily activities, as well as relapse to cannabis use. Sample size in the relapse group was small and the use of a non-treatment seeking population requires findings to be replicated in clinical samples.

  1. Meta-Analysis Reveals Significant Association of the 3'-UTR VNTR in SLC6A3 with Alcohol Dependence. (United States)

    Ma, Yunlong; Fan, Rongli; Li, Ming D


    Although many studies have analyzed the association of 3'-untranslated region variable-number tandem repeat (VNTR) polymorphism in SLC6A3 with alcohol dependence (AD), the results remain controversial. This study aimed to determine whether this variant indeed has any genetic effect on AD by integrating 17 reported studies with 5,929 participants included. The A9-dominant genetic model that considers A9-repeat and non-A9 repeat as 2 genotypes and compared their frequencies in alcoholics with that in controls was adopted. Considering the potential influence of ethnicity, differences in diagnostic criteria of AD, and alcoholic subgroups, stratified meta-analyses were conducted. There existed no evidence for the presence of heterogeneity among the studied samples, indicating the results under the fixed-effects model are acceptable. We found a significant association of VNTR A9 genotypes with AD in all ethnic populations (pooled odds ratio [OR] 1.12; 95% confidence interval [CI] 1.00, 1.25; p = 0.045) and the Caucasian population (pooled OR 1.15; 95% CI 1.01, 1.31; p = 0.036). We also found VNTR A9 genotypes to be significantly associated with alcoholism as defined by the DSM-IV criteria (pooled OR 1.18; 95% CI 1.03, 1.36; p = 0.02). Further, we found a significant association between VNTR A9 genotypes and alcoholism associated with alcohol withdrawal seizure or delirium tremens (pooled OR 1.55; 95% CI 1.24, 1.92; p = 1.0 × 10(-4) ). In all these meta-analyses, no evidence of publication bias was detected. We concluded that the VNTR polymorphism has an important role in the etiology of AD, and individuals with at least 1 A9 allele are more likely to be dependent on alcohol than persons carrying the non-A9 allele.

  2. Seizure metaphors differ in patients' accounts of epileptic and psychogenic nonepileptic seizures. (United States)

    Plug, Leendert; Sharrack, Basil; Reuber, Markus


    To increase understanding of the subjective symptomatology of seizure experiences and improve differential diagnosis by studying the seizure metaphors used by patients with (psychogenic) nonepileptic seizures (NES) and epilepsy. Twenty-one unselected patients taking part in this study were admitted for 48 h of video-EEG (electroenceophalography) observation because of uncertainty about the diagnosis. Eight were proven to have epilepsy, 13 to have psychogenic nonepileptic seizures (PNES). During their admission, patients were interviewed by a neurologist. A linguist blinded to the medical diagnosis identified and categorized all seizure metaphors in verbatim transcripts. Between-group comparisons and logistic regression analysis were carried out. Of 382 metaphors identified, 80.8% conceptualized seizures as an agent/force, event/situation, or space/place. Most patients used metaphors from all categories, but patients with epilepsy and PNES showed preferences for different metaphoric concepts (differences p = 0.009 to p = 0.039). Patients with epilepsy preferred metaphors depicting the seizure as an agent/force or event/situation. PNES patients more often used metaphors of space/place. Logistic regression analyses predicted the diagnosis of PNES or epilepsy correctly in 85.7% of cases (based on different metaphor types in the each category) or 81.0% (based on all metaphor tokens). Patients with epilepsy and PNES have different preferences in the metaphoric conceptualization of their seizures. Epileptic seizures are described as a more external, self-directed entity than PNES, which are depicted as a state or place patients go through. The differentiating value of metaphoric conceptualizations suggests that metaphor preference could form the basis of future diagnostic questionnaires or other diagnostic tools.

  3. Seizures after intravenous tramadol given as premedication

    Directory of Open Access Journals (Sweden)

    Lalit Kumar Raiger


    Full Text Available A 35-year-old, 50-kg female with a history of epilepsy was scheduled for elective breast surgery (fibroadenoma under general anaesthesia. She was given glycopyrrolate 0.2 mg, ondansetron 4 mg and tramadol 100 mg i.v. as premedication. Within 5 min, she had an acute episode of generalised tonic-clonic seizure that was successfully treated with 75 mg thiopentone i.v. and after 30 min, she was given general anaesthesia with endotracheal intubation. Surgery, intra-operative period, extubation and post-operative period were uneventful. We conclude that tramadol may provoke seizures in patients with epilepsy even within the recommended dose range.

  4. Emergence of semiology in epileptic seizures. (United States)

    Chauvel, Patrick; McGonigal, Aileen


    Semiology, the manifestation of epilepsy, is dependent upon electrical activity produced by epileptic seizures that are organized within existing neural pathways. Clinical signs evolve as the epileptic discharge spreads in both time and space. Studying the relation between these, of which the temporal component is at least as important as the spatial one, is possible using anatomo-electro-clinical correlations of stereoelectroencephalography (SEEG) data. The period of semiology production occurs with variable time lag after seizure onset and signs then emerge more or less rapidly depending on seizure type (temporal seizures generally propagating more slowly and frontal seizures more quickly). The subset of structures involved in semiological production, the "early spread network", is tightly linked to those constituting the epileptogenic zone. The level of complexity of semiological features varies according to the degree of involvement of the primary or associative cortex, with the former having a direct relation to peripheral sensory and motor systems with production of hallucinations (visual and auditory) or elementary sensorimotor signs. Depending on propagation pattern, these signs can occur in a "march" fashion as described by Jackson. On the other hand, seizures involving the associative cortex, having a less direct relation with the peripheral nervous system, and necessarily involving more widely distributed networks manifest with altered cognitive and/or behavioral signs whose neural substrate involves a network of cortical structures, as has been observed for normal cognitive processes. Other than the anatomical localization of these structures, the frequency of the discharge is a crucial determinant of semiological effect since a fast (gamma) discharge will tend to deactivate normal function, whereas a slower theta discharge can mimic physiological function. In terms of interaction between structures, the degree of synchronization plays a key role in

  5. Alcohol’s Effects on Sleep in Alcoholics


    Brower, Kirk J.


    Sleep problems, which can have significant clinical and economic consequences, are more common among alcoholics than among nonalcoholics. During both drinking periods and withdrawal, alcoholics commonly experience problems falling asleep and decreased total sleep time. Other measures of sleep are also disturbed. Even alcoholics who have been abstinent for short periods of time (i.e., several weeks) or extended periods of time (i.e., several years) may experience persistent sleep abnormalities...

    Symptomatic paroxysmal hypertension without significantly elevated catecholamine concentrations and with no evidence of an underlying adrenal tumor is known as pseudopheochromocytoma. We describe the case of a female patient with paroxysmal hypertensive crises accompanied by headache, vertigo, tachycardia, nausea and altered mental status. Previously, she was treated for a longer period with alprazolam due to panic disorder. Causes of secondary hypertension were excluded. Neurological triggers (intracranial tumor, cerebral vascular lesions, hemorrhage, and epilepsy) could not be detected. Setting of the diagnosis of pseudopheochromocytoma treatment was initiated with alpha- and beta-blockers resulting in reduced frequency of symptoms. Alprazolam was restarted at a daily dose of 1 mg. The patient's clinical condition improved rapidly and the dosage of alpha- and beta-blockers could be decreased. We conclude that the withdrawal of an anxiolytic therapeutic regimen may generate sympathetic overdrive resulting in life-threatening paroxysmal malignant hypertension and secondary encephalopathy. We emphasize that pseudopheochromocytoma can be diagnosed only after exclusion of the secondary causes of hypertension. We highlight the importance of a psychopharmacological approach to this clinical entity.

  7. A systematic review of suggestive seizure induction for the diagnosis of psychogenic nonepileptic seizures. (United States)

    Popkirov, Stoyan; Grönheit, Wenke; Wellmer, Jörg


    Suggestive seizure induction is a widely used method for diagnosing psychogenic nonepileptic seizures (PNES). Despite seven decades of multidisciplinary research, however, there is still no unified protocol, no definitive agreement on the ethical framework and no consensus on diagnostic utility. This systematic review surveys the evidence at hand and addresses clinically relevant aspects of suggestive seizure induction. In addition to its use for facilitating the diagnostic process, its mechanism of action and utility in elucidating the psychopathology of PNES will be discussed.

  8. Hyperkinetic motor seizures: a common semiology generated by two different cortical seizure origins. (United States)

    Vaugier, Lisa; McGonigal, Aileen; Lagarde, Stanislas; Trébuchon, Agnes; Szurhaj, William; Derambure, Philippe; Bartolomei, Fabrice


    We report a 37-year-old, right-handed patient with drug-resistant focal epilepsy whose seizures were characterized by explosive hyperkinetic behaviour. Video-SEEG revealed bifocal organization of epilepsy with two distinct cortical origins of seizures: the right temporal pole and left temporal lateral and perisylvian cortex. Irrespective of the cortical pattern of seizure onset, the hyperkinetic semiology was extremely similar. This supports a major role for "final common pathway" subcortical circuits in the genesis of the hyperkinetic semiology in this patient.

  11. Ictal asystole mimicking seizure deterioration in temporal lobe epilepsy. (United States)

    Guldiken, Baburhan; Hartl, Elisabeth; Rémi, Jan; Noachtar, Soheyl


    We report on a patient with temporal lobe epilepsy, secondary to a left lateral temporal cavernoma, in whom the change in seizure semiology suggested recurrence of secondary generalized seizures. Anticonvulsive medication previously controlled secondary generalized seizures over a period of years but focal seizures continued at a lower rate. Continuous video-EEG monitoring revealed ictal asystole associated with myoclonic syncope and falls during focal seizures arising from the left temporal lobe. After implantation of a cardiac pacemaker, no more falls occurred during the focal seizures. In conclusion, recurrence of seizure-associated falls is typically attributed to recurrence of secondary generalized seizures, however, ictal asystole should be considered in selected epilepsy patients as a differential diagnosis of falls.

    Mandić-Gajić Gordana


    Full Text Available Background/Aim. The relationship between alcoholism and depression is observed in clinical trials. The factors which could predict persistence of secondary depression after alcohol withdrawal are not enough explored on admission. The differences between depressed (DA and non-depressed (NDA alcoholics regarding the degrees of severity of withdrawal, severity of depression and the intensity of cognitive dysfunctions were explored on admission to investigate possibility of prediction of the development of secondary depression in alcoholics. Methods. A group of primary male alcoholics (n=86 was recruited during inpatient treatment. After 4 weeks alcoholics were divided in the DA group (n=43 and NDA (n=43 group according to the score on the Hamilton Depression Rating Scale (HAM-D. Clinical assessment of withdrawal, scoring on the Alcohol Dependency Severity Scale- ASD, and scoring on the Mini Mental Scale-MMSE were performed in all the participants on admission. The differences between the groups were tested by the Student's t-test. Results. The DA group showed the significantly higher severity of depression, higher levels of alcohol withdrawal symptoms and cognitive dysfunctions than the NDA group on admission. Conclusion. The specific group of depressive alcoholics was shown to be characterized by the higher severity of alcoholism and depression on admission, which could predict prolonged, secondary depression. Early detection and concurrent therapy of secondary depression could improve the treatment, and reduce the relapse of alcoholism.

  16. Rapidly Learned Identification of Epileptic Seizures from Sonified EEG

    Directory of Open Access Journals (Sweden)

    Psyche eLoui


    Full Text Available Sonification refers to a process by which data are converted into sound, providing an auditory alternative to visual display. Currently, the prevalent method for diagnosing seizures in epilepsy is by visually reading a patient’s electroencephalogram (EEG. However, sonification of the EEG data provides certain advantages due to the nature of human auditory perception. We hypothesized that human listeners will be able to identify seizures from EEGs using the auditory modality alone, and that accuracy of seizure identification will increase after a short training session. Here we describe an algorithm we have used to sonify EEGs of both seizure and non-seizure activity, followed by a training study in which subjects listened to short clips of sonified EEGs and determine whether each clip was of seizure or normal activity, both before and after a short training session. Results show that before training subjects performed at chance level in differentiating seizures vs. non-seizures, but there was a significant improvement of accuracy after the training session. After training, subjects successfully distinguished seizures from non-seizures using the auditory modality alone. Further analyses using signal detection theory demonstrated improvement in sensitivity and reduction in response bias as a result of training. This study demonstrates the potential of sonified EEGs to be used for the detection of seizures. Future studies will attempt to increase accuracy using novel training and sonification modifications, with the goals of managing, predicting, and ultimately controlling seizures using sonification as a possible biofeedback-based intervention for epilepsy.

  17. A network analysis of the dynamics of seizure. (United States)

    Burns, Samuel P; Sritharan, Duluxan; Jouny, Christophe; Bergey, Gregory; Crone, Nathan; Anderson, William S; Sarma, Sridevi V


    Seizures are events that spread through the brain's network of connections and create pathological activity. To understand what is occurring in the brain during seizure we investigated the time progression of the brain's state from seizure onset to seizure suppression. Knowledge of a seizure's dynamics and the associated spatial structure is important for localizing the seizure foci and determining the optimal location and timing of electrical stimulation to mitigate seizure development. In this study, we analyzed intracranial EEG data recorded in 2 human patients with drug-resistant epilepsy prior to undergoing resection surgery using network analyses. Specifically, we computed a time sequence of connectivity matrices from iEEG (intracranial electroencephalography) recordings that represent network structure over time. For each patient, connectivity between electrodes was measured using the coherence in the band of frequencies with the strongest modulation during seizure. The connectivity matrices' structure was analyzed using an eigen-decomposition. The leading eigenvector was used to estimate each electrode's time dependent centrality (importance to the network's connectivity). The electrode centralities were clustered over the course of each seizure and the cluster centroids were compared across seizures. We found, for each patient, there was a consistent set of centroids that occurred during each seizure. Further, the brain reliably evolved through the same progression of states across multiple seizures including characteristic onset and suppression states.

  19. Out-of-body experiences associated with seizures

    Directory of Open Access Journals (Sweden)

    Bruce eGreyson


    Full Text Available Alterations of consciousness are critical factors in the diagnosis of epileptic seizures. With these alterations in consciousness, some persons report sensations of separating from the physical body, experiences that may in rare cases resemble spontaneous out-of-body experiences. This study was designed to identify and characterize these out-of-body-like subjective experiences associated with seizure activity. 55% of the patients in this study recalled some subjective experience in association with their seizures. Among our sample of 100 patients, 7 reported out-of-body experiences associated with their seizures. We found no differentiating traits that were associated with patients’ reports of out-of-body experiences, in terms of either demographics; medical history, including age of onset and duration of seizure disorder, and seizure frequency; seizure characteristics, including localization, lateralization, etiology, and type of seizure, and epilepsy syndrome; or ability to recall any subjective experiences associated with their seizures. Reporting out-of-body experiences in association with seizures did not affect epilepsy-related quality of life. It should be noted that even in those patients who report out-of-body experiences, such sensations are extremely rare events that do not occur routinely with their seizures. Most patients who reported out-of-body experiences described one or two experiences that occurred an indeterminate number of years ago, which precludes the possibility of associating the experience with the particular characteristics of that one seizure or with medications taken or other conditions at the time.

  2. Microglial depletion alters the brain neuroimmune response to acute binge ethanol withdrawal. (United States)

    Walter, T Jordan; Crews, Fulton T


    Recent studies have implicated microglia-the resident immune cells of the brain-in the pathophysiology of alcoholism. Indeed, post-mortem alcoholic brains show increased microglial markers and increased immune gene expression; however, the effects of ethanol on microglial functioning and how this impacts the brain remain unclear. In this present study, we investigate the effects of acute binge ethanol on microglia and how microglial depletion changes the brain neuroimmune response to acute binge ethanol withdrawal. C57BL/6J mice were treated intragastrically with acute binge ethanol for time course and dose-response studies. Cultured mouse BV2 microglia-like cells were treated with ethanol in vitro for time course studies. Mice were also administered the colony stimulating factor 1 receptor (CSF1R) inhibitor PLX5622 to deplete microglia from the brain. These mice were subsequently treated with acute binge ethanol and sacrificed during withdrawal. Brain and BV2 mRNA were isolated and assessed using RT-PCR to examine expression of microglial and neuroimmune genes. Acute binge ethanol biphasically changed microglial (e.g., Iba1, CD68) gene expression, with initial decreases during intoxication and subsequent increases during withdrawal. Acute ethanol withdrawal dose dependently increased neuroimmune gene (e.g., TNFα, Ccl2, IL-1ra, IL-4) expression beginning at high doses. BV2 cells showed biphasic changes in pro-inflammatory (e.g., TNFα, Ccl2) gene expression following ethanol treatment in vitro. Administration of PLX5622 depleted microglia from the brains of mice. Although some neuroimmune genes were reduced by microglial depletion, many others were unchanged. Microglial depletion blunted pro-inflammatory (e.g., TNFα, Ccl2) gene expression and enhanced anti-inflammatory (e.g., IL-1ra, IL-4) gene expression during acute binge ethanol withdrawal. These studies find acute binge ethanol withdrawal increases microglial and neuroimmune gene expression. Ethanol exposure

  4. Using Dictionary Pair Learning for Seizure Detection. (United States)

    Ma, Xin; Yu, Nana; Zhou, Weidong


    Automatic seizure detection is extremely important in the monitoring and diagnosis of epilepsy. The paper presents a novel method based on dictionary pair learning (DPL) for seizure detection in the long-term intracranial electroencephalogram (EEG) recordings. First, for the EEG data, wavelet filtering and differential filtering are applied, and the kernel function is performed to make the signal linearly separable. In DPL, the synthesis dictionary and analysis dictionary are learned jointly from original training samples with alternating minimization method, and sparse coefficients are obtained by using of linear projection instead of costly [Formula: see text]-norm or [Formula: see text]-norm optimization. At last, the reconstructed residuals associated with seizure and nonseizure sub-dictionary pairs are calculated as the decision values, and the postprocessing is performed for improving the recognition rate and reducing the false detection rate of the system. A total of 530[Formula: see text]h from 20 patients with 81 seizures were used to evaluate the system. Our proposed method has achieved an average segment-based sensitivity of 93.39%, specificity of 98.51%, and event-based sensitivity of 96.36% with false detection rate of 0.236/h.

    Purpose To report bilateral hemorrhagic retinopathy in an adult female following lumbar spinal surgery and seizure. Case Report A 38 year old female presented with bilateral blurry vision and spots in the visual field. The patient had lumbar spondylosis surgery which was complicated by a dural tear with persistent cerebrospinal fluid leak. Visual symptoms started immediately following witnessed seizure-like activity. At presentation, visual acuity was 20/100 and 20/25 in the right and left eye, respectively. Dilated fundus examination demonstrated bilateral hemorrhagic retinopathy with subhyaloid, intraretinal and subretinal involvement. At 4 month follow up, visual acuity improved to 20/60 and 20/20 in the right and left eye, respectively. Dilated fundus examination and fundus photography showed resolution of retinal hemorrhages in both eyes. Conclusions The first case of bilateral hemorrhagic retinopathy following lumbar spondylosis surgery and witnessed seizure in an adult was reported. Ophthalmic examination may be warranted following episodes of seizure in adults. PMID:26099062

    The aim of this study was to investigate the predictive factors and identify the characteristics of the seizure-induced signal changes on MRI (SCM) in patients with first seizures. We conducted a retrospective study of patients with first seizures from March 2010 to August 2014. The inclusion criteria for this study were patients with 1) first seizures, and 2) MRI and EEG performed within 24h of the first seizures. The definition of SCM was hyper-intensities in the brain not applying to cerebral arterial territories. Multivariate logistic regression was performed with or without SCM as a dependent variable. Of 431 patients with seizures visiting the ER, 69 patients met the inclusion criteria. Of 69 patients, 11 patients (15.9%) had SCM. Epileptiform discharge on EEG (OR 29.7, 95% CI 1.79-493.37, p=0.018) was an independently significant variable predicting the presence of SCM in patients with first seizures. In addition, the topography of SCM was as follows; i) ipsilateral hippocampus, thalamus and cerebral cortex (5/11), ii) unilateral cortex (4/11), iii) ipsilateral thalamus and cerebral cortex (1/11), iv) bilateral hippocampus (1/11). Moreover, 6 out of 7 patients who underwent both perfusion CT and MRI exhibited unilateral cortical hyperperfusion with ipsilateral thalamic involvement reflecting unrestricted vascular territories. There is an association between epileptiform discharges and SCM. Additionally, the involvement of the unilateral cortex and ipsilateral thalamus in SCM and its hyperperfusion state could be helpful in differentiating the consequences of epileptic seizures from other pathologies.

    Ebrahim Koochaki


    Full Text Available Background: The most common reason for seizure in elderly duration is the stroke. This study was conducted aiming to assess the frequency of seizure attack occurrence in those patients. Materials and Methods: This investigation was carried out through a cross-sectional method for one year on 330 patients admitted to the neurology ward as diagnosed with stroke. The required data was collected through the researcher-made questionnaire from the patients suffering from stoke which was diagnosed based on clinical findings, CT-Scan and MRI as required. Results: Among 330 patient suffering from stroke (162 men and 168 women, 48 cases (14.5% were suffering from seizure. Six percent of the patients had early seizure and another 8.5% had late seizure. Among 162 men suffering from the stroke, 32 ones were without seizures and 30 men were suffering the seizure. A number of 150 women out of total 168 ones suffering from the stroke, had no seizure and 18 others had seizures; frequency of seizure occurrence was more in male samples (p=0.044. In the people under 60 year, there were mostly early types of seizure (45% and in the age range above 60 year, it was mostly late type (89.3%. A 68.5% of the patients suffering from the seizure had experienced ischemic stroke. However, the frequency of seizure occurrence in the patients with hemorrhagic stroke was statistically greater (p=0.003. Conclusion: This examination showed that occurrence of seizure attacks in the people with stroke is 14.5% and it is seen more in the hemorrhagic strokes than ischemic ones. The frontoparietal area is the most common location involved and tonic clonic was the most common seizure in the patients suffering from it who have experienced the stroke

  17. Bilateral Paramedian Thalamic Infarction Initially Presenting as a Convulsive Seizure

    Directory of Open Access Journals (Sweden)

    Jianping Wang


    Full Text Available Bithalamic infarctions initially presenting as a convulsive seizure are rarely reported and, to our best knowledge, have never been reported in China. Here, we present a patient with convulsive seizure at the onset of bilateral paramedian thalamic infarction. The diffusion-weighted imaging revealed that the infarct area is supplied by Percheron artery. Associated with the relationship between seizure and centrencephalic system and reticular formation as previously reported, we suggest that seizure could be the onset symptom of paramedian thalamic infarction. Physicians should recognize this condition, because both seizure control and early ischemic stroke management are required.

  18. Pediatric intracerebral hemorrhage: acute symptomatic seizures and epilepsy. (United States)

    Beslow, Lauren A; Abend, Nicholas S; Gindville, Melissa C; Bastian, Rachel A; Licht, Daniel J; Smith, Sabrina E; Hillis, Argye E; Ichord, Rebecca N; Jordan, Lori C


    Seizures are believed to be common presenting symptoms in neonates and children with spontaneous intracerebral hemorrhage (ICH). However, few data are available on the epidemiology of acute symptomatic seizures or the risk for later epilepsy. To define the incidence of and explore risk factors for seizures and epilepsy in children with spontaneous ICH. Our a priori hypotheses were that younger age at presentation, cortical involvement of ICH, acute symptomatic seizures after presentation, ICH due to vascular malformation, and elevated intracranial pressure requiring urgent intervention would predict remote symptomatic seizures and epilepsy. Prospective cohort study conducted between March 1, 2007, and January 1, 2012. Three tertiary care pediatric hospitals. Seventy-three pediatric subjects with spontaneous ICH including 20 perinatal (≥37 weeks' gestation to 28 days) and 53 childhood subjects (>28 days to Acute symptomatic seizures (clinically evident and electrographic-only seizures within 7 days), remote symptomatic seizures, and epilepsy. Acute symptomatic seizures occurred in 35 subjects (48%). Acute symptomatic seizures as a presenting symptom of ICH occurred in 12 perinatal (60%) and 19 childhood (36%) subjects (P = .07). Acute symptomatic seizures after presentation occurred in 7 children. Electrographic-only seizures were present in 9 of 32 subjects (28%) with continuous electroencephalogram monitoring. One-year and 2-year remote symptomatic seizure-free survival rates were 82% (95% CI, 68-90) and 67% (95% CI, 46-82), respectively. One-year and 2-year epilepsy-free survival rates were 96% (95% CI, 83-99) and 87% (95% CI, 65-95), respectively. Elevated intracranial pressure requiring acute intervention was a risk factor for seizures after presentation (P = .01; Fisher exact test), remote symptomatic seizures, and epilepsy (P = .03, and P = .04, respectively; log-rank test). Presenting seizures are common in perinatal and childhood ICH. Continuous

  20. Regulation of operant ethanol-reinforced behavior is genetically independent of regulation of withdrawal severity in WSP and WSR mice. (United States)

    Barbera, T J; Baca, K; George, F R


    Selectively bred withdrawal seizure prone (WSP1 and WSP2) and withdrawal seizure resistant (WSR1 and WSR2) mice were used to test the extent to which severity of ethanol withdrawal response is predictive of the reinforcing effects of ethanol. Mice were systematically introduced to ethanol under a fixed ratio 1 (FR 1) schedule using adjunctive drinking methods. There were no significant differences in ethanol consumption between the lines during training. Subsequently, responding for ethanol concentrations of 8%, 0% (vehicle control), and 8% retest under a FR 1 schedule in the absence of food induction was measured. Group data showed that ethanol did not serve as a reinforcer in the test phase within any of the four lines, and there were no significant line differences in rate of responding, intake, or blood ethanol concentrations (BEC). Mice were next tested for responding for ethanol under a FR 4 schedule. Again, ethanol did not serve as a reinforcer for any of the four groups, and there were no significant differences between the lines. However, further analysis showed that there were individual differences in responding within each group, some animals were apparently reinforced by ethanol, while others showed no reinforcement and some appeared to avoid ethanol. There was no systematic pattern within or between groups for these individual differences in responding. Thus, both the group results as well as the behavior patterns of individual animals are consistent with the conclusion that genes regulating rewarding effects of ethanol appear to be segregating randomly across groups and are independent of genes mediating ethanol withdrawal severity.(ABSTRACT TRUNCATED AT 250 WORDS)

  1. Antagonist-Elicited Cannabis Withdrawal in Humans (United States)

    Gorelick, David A.; Goodwin, Robert S.; Schwilke, Eugene; Schwope, David M.; Darwin, William D.; Kelly, Deanna L.; McMahon, Robert P.; Liu, Fang; Ortemann-Renon, Catherine; Bonnet, Denis; Huestis, Marilyn A.


    Cannabinoid CB1 receptor antagonists have potential therapeutic benefits, but antagonist-elicited cannabis withdrawal has not been reported in humans. Ten male daily cannabis smokers received 8 days of increasingly frequent 20-mg oral Δ9-tetrahydrocannabinol (THC) dosages (40–120 mg/d) around-the-clock to standardize cannabis dependence while residing on a closed research unit. On the ninth day, double-blind placebo or 20- (suggested therapeutic dose) or 40-mg oral rimonabant, a CB1-cannabinoid receptor antagonist, was administered. Cannabis withdrawal signs and symptoms were assessed before and for 23.5 hours after rimonabant. Rimonabant, THC, and 11-hydroxy-THC plasma concentrations were quantified by mass spectrometry. The first 6 subjects received 20-mg rimonabant (1 placebo); the remaining 4 subjects received 40-mg rimonabant (1 placebo). Fourteen subjects enrolled; 10 completed before premature termination because of withdrawal of rimonabant from clinical development. Three of 5 subjects in the 20-mg group, 1 of 3 in the 40-mg group, and none of 2 in the placebo group met the prespecified withdrawal criterion of 150% increase or higher in at least 3 visual analog scales for cannabis withdrawal symptoms within 3 hours of rimonabant dosing. There were no significant associations between visual analog scale, heart rate, or blood pressure changes and peak rimonabant plasma concentration, area-under-the-rimonabant-concentration-by-time curve (0–8 hours), or peak rimonabant/THC or rimonabant/(THC + 11-hydroxy-THC) plasma concentration ratios. In summary, prespecified criteria for antagonist-elicited cannabis withdrawal were not observed at the 20- or 40-mg rimonabant doses. These data do not preclude antagonist-elicited withdrawal at higher rimonabant doses. PMID:21869692

  3. Seizure semiology of lesional frontal lobe epilepsies in children. (United States)

    Battaglia, D; Lettori, D; Contaldo, I; Veredice, C; Sacco, A; Vasco, J; Martinelli, D; Chieffo, D; Tartaglione, T; Colosimo, C; Di Rocco, C; Guzzetta, F


    The aim of the study was to analyse the semiology of seizures in children with frontal lobe epilepsy (FLE) and to compare them with other paediatric cohorts described in the literature as well as with adult counterparts. We analysed 174 registered seizures of 18 cases under 12 years with lesional epilepsy whose frontal origin was defined by the concordance of neuroimaging and ictal electrographic findings, and confirmed by surgery in the six cases operated on. Seizures were generally short, with a high daily frequency and usually related to sleep. The most characteristic semiological pattern consisted of complex motor seizures, particularly hypermotor. Often seizures corresponded to a mixture of different semiological patterns (tonic, gelastic, automotor, hypermotor, versive) presenting in the same seizure, often as a unique type in the same patient. With regard to several aspects the semiology of FLE in our cohort looks like that reported in adult series, in particular as to the frequency of complex motor seizures. However, our cohort was also characterised by a more protean array of seizure semiology, stressing the occurrence of seizures typically present in adults (versive and complex motor) and of some seizure patterns more characteristic in children such as epileptic spasms; moreover, the rare occurrence of secondarily generalised tonic clonic seizures (SGTCS) was confirmed.

    This study aimed to determine the accuracy of seizure diagnosis by semiological analysis and to assess the factors that affect diagnostic reliability. A total of 150 video clips of seizures from 50 patients (each with three seizures of the same type) were observed by eight epileptologists, 12 neurologists, and 20 physicians (internists). The videos included 37 series of epileptic seizures, eight series of physiologic nonepileptic events (PNEEs), and five series of psychogenic nonepileptic seizures (PNESs). After observing each video, the doctors chose the diagnosis of epileptic seizures or nonepileptic events for the patient; if the latter was chosen, they further chose the diagnosis of PNESs or PNEEs. The overall diagnostic accuracy rate for epileptic seizures and nonepileptic events increased from 0.614 to 0.660 after observations of all three seizures (p semiological diagnosis of seizures is greatly affected by the seizure type as well as the doctor's experience. Although the overall reliability is limited, it can be improved by observing more seizures. Copyright © 2014 Elsevier Inc. All rights reserved.

  5. Jacksonian seizure as the relapse symptom of multiple sclerosis

    Directory of Open Access Journals (Sweden)

    Mohammad Reza Najafi


    Full Text Available Epilepsy is more common in patients with multiple sclerosis (MS than in the general population, occurring in 2-3% of patients. Convulsions may be either tonic-clonic in nature or partial complex. In these individuals, seizures most likely result from lesions present in the cerebral cortex and subcortical white matter. A Jacksonian seizure is a type of simple partial seizure characterized by abnormal movements that begin in one group of muscles and progress to adjacent groups of muscles. We describe a case of Jacksonian seizure as the relapse symptom of MS. Focal motor seizures of this patient have been observed before and presumably marking the clinical onset or during acute bouts of MS. In this case, Jacksonian seizures appear to be the sign of a flare of MS, while the majority of seizures had been reported occur unrelated to MS relapses.

  6. Role of biomarkers in differentiating new-onset seizures from psychogenic nonepileptic seizures

    Mahendra Javali


    Full Text Available Introduction: Review of literature revealed very limited studies considering a combination of serum prolactin (PRL and serum creatine kinase (CK as markers for differentiating epileptic and psychogenic nonepileptic seizures (PNES. Therefore, in the present study, we analyzed the role of serum PRL and serum CK, individually and in combination. Methodology: This prospective study was conducted in a tertiary care medical teaching hospital over a period of 18 months. Patients aged over 15 years suspected to have new-onset seizures presenting within 5 h of ictus were included in this study. CK, serum PRL was measured at 0–1, 1–3, and 3–5 h after seizures. Results: Hundred subjects were studied for the role of serum PRL and serum CK in differentiating epileptic and PNES. The mean age was 42.24 years with a male:female ratio of 1.27:1. All patients of generalized tonic–clonic seizures (GTCS, who presented within 1 h, had elevated PRL, whereas 75% of patients with partial seizures had elevated PRL within 1 h of presentation. Nearly 91.66% of patients with GTCS who presented within 1 h had elevated CPK, whereas 70% of patients with partial seizures had elevated CPK. None of the patients diagnosed with PNES showed rise in either of the markers. Conclusion: In the present study, none of the patients with PNES showed raise in either serum PRL or CK. However, there was no correlation between the types of seizure and PRL or serum CK levels.

  7. Control rod excess withdrawal prevention device

    International Nuclear Information System (INIS)

    Takayama, Yoshihito.


    Excess withdrawal of a control rod of a BWR type reactor is prevented. That is, the device comprises (1) a speed detector for detecting the driving speed of a control rod, (2) a judging circuit for outputting an abnormal signal if the driving speed is greater than a predetermined level and (3) a direction control valve compulsory closing circuit for controlling the driving direction of inserting and withdrawing a control rod based on an abnormal signal. With such a constitution, when the with drawing speed of a control rod is greater than a predetermined level, it is detected by the speed detector and the judging circuit. Then, all of the direction control valve are closed by way of the direction control valve compulsory closing circuit. As a result, the operation of the control rod is stopped compulsorily and the withdrawing speed of the control rod can be lowered to a speed corresponding to that upon gravitational withdrawal. Accordingly, excess withdrawal can be prevented. (I.S)

  8. Effect of Shankhpushpi on Alcohol Addiction in Mice. (United States)

    Heba, Mahi; Faraz, Sana; Banerjee, Sugato


    Alcohol addiction is a worldwide problem. It has mainly two components: dependence and withdrawal. Characteristic properties of most anti-addictive compounds include anti-anxiety, anticonvulsant, antidepressant, and nootropic actions. Shankhpushpi ( Convolvulus pluricaulis . Convolvulaceae), known ethnopharmacologically as brain tonic, possess all the properties mentioned above. Here, we screen shankhpushpi for possible anti-addictive potential. Effect of shankhpushpi churna was measured on ethanol withdrawal anxiety using elevated plus maze. The role of shankhpushpi on chronic ethanol consumption (21 days) was measured using two bottle choice protocol of voluntary drinking. We also measured the effect of the above herb on cortico-hippocampal GABA levels. Shankhpushpi was found to reduce alcohol withdrawal anxiety in a dose-dependent manner. The herb also decreased ethanol intake and increased water intake significantly ( P < 0.001) after 4 days of administration. Both these effects were blocked ( P < 0.001) by GABAA antagonist suggesting the role of GABAA receptor. Chronic administration of shankhpushpi also significantly ( P < 0.01) increased cortico-hippocampal GABA levels in mice. Shankhpushpi reduced both alcohol dependence and withdrawal in a GABAA-dependent manner, thus showing anti-addictive potential. Shankhpushpi prevented ethanol withdrawal anxiety and alcohol addiction in a GABA A -dependent manner.

  9. [Causes of the people death from drunkenness and alcoholism]. (United States)

    Erokhin, Iu A; Paukov, V S; Kirillov, Iu A


    We analyzed causes of 1008 people death, who abused by alcohol. Among them 2 groups were separated out: people died due to drunkenness and due to alcoholism. The structure of the death was similar in the both groups, however depended on alcoholism stages. The major cause of the death in group of drunkenness people was acute heart insufficiency, less commonly--lung pathology, and very rarely--brain vessels pathology and liver cirrhosis. In group of people, who died due to alcoholism, lung pathology was the major cause of these deaths, acute heart insufficiency was occurred less commonly, and very rare brain pathology because of delirium tremens or alcohol withdrawal syndrome, as so liver cirrhosis with complications. Hemorrhagic pancreonecrosis after alcoholic excess was found out in both groups, but it was more often in people, who died due to drunkenness. Obtained results show importance of chronic alcoholism identification as a disease with several stages including drunkenness and alcoholism.

  10. Local cerebral metabolism during partial seizures

    Energy Technology Data Exchange (ETDEWEB)

    Engel, J. Jr.; Kuhl, D.E.; Phelps, M.E.; Rausch, R.; Nuwer, M.


    Interictal and ictal fluorodeoxyglucose scans were obtained with positron CT from four patients with spontaneous recurrent partial seizures, one with epilepsia partialis continua, and one with a single partial seizure induced by electrical stimulation of the hippocampus. Ictal metabolic patterns were different for each patient studied. Focal and generalized increased and decreased metabolism were observed. Ictal hypermetabolism may exceed six times the interictal rate and could represent activation of excitatory or inhibitory synapses in the epileptogenic region and its projection fields. Hypometabolism seen on ictal scans most likely reflects postictal depression and may indicate projection fields of inhibited neurons. No quantitative relationship between alterations in metabolism and EEG or behavioral measurements of ictal events could be demonstrated.

    alta de la UTI. CONCLUSIONES: La droga escogida para el tratamiento del síndrome de abstinencia alcohólico es el benzodiazepínico. No obstante, en el presente relato, solamente el uso coadyuvante de clonidina consiguió proporcionar tratamiento adecuado al paciente.BACKGROUND AND OBJECTIVES: Sedation of patients with past history of alcohol and drug abuse in Intensive Care Units (ICU is a challenge due to the high incidence of sedative drugs tolerance and withdrawal syndromes. This report aimed at describing a case of a young patient admitted to the ICU who developed alcohol withdrawal syndrome and tolerance to sedatives, resolved only after clonidine administration. CASE REPORT: Male patient, 18 years old, alcohol, tobacco, cocaine and marijuana abuser, victim of firearm accident, who was admitted to the ICU in the first post-enterectomy day, after gastric content aspiration during tracheal re-intubation. Clinical evolution was: vasoactive drugs up to the 4th day; bilateral bronchopneumonia with pleural effusion and need for artificial ventilation up to the 15th day. Initial sedation scheme was the association of midazolam and fentanyl. As from the 4th day, patient presented with several psychomotor agitation episodes, even after the association of lorazepam in the 6th day. In the 9th day, patient received the largest doses but remained agitated. Dexmedetomidine was associated, which has decreased other drug doses in 35% and has improved agitation. In the 12th day, midazolam and dexmedetomidine were replaced by propofol infusion with worsening of agitation. In the 13th day, clonidine was associated to the sedation scheme with total resolution of agitation. Propofol was withdrawn in the 14th day, fentanyl was maintained and midazolam infusion was restarted, with doses 75% and 65% lower as compared to peak doses of such drugs. Patient was extubated in the 15th day and was discharged from ICU. CONCLUSIONS: Benzodiazepines should remain the drugs of choice for the

  12. The Presence of Consciousness in Absence Seizures (United States)

    Bayne, Tim


    This paper examines three respects in which the study of epileptic absence seizures promises to inform our understanding of consciousness. Firstly, it has the potential to bear on debates concerning the behavioural and cognitive functions associated with consciousness. Secondly, it has the potential to illuminate the relationship between background states (or ‘levels’) of consciousness and the contents of consciousness. Thirdly, it has the potential to bear on our understanding of the unity of consciousness. PMID:21447898

  15. Exogenous Cushing's syndrome and glucocorticoid withdrawal. (United States)

    Hopkins, Rachel L; Leinung, Matthew C


    Glucocorticoid therapy in various forms is extremely common for a wide range of inflammatory, autoimmune, and neoplastic disorders. It is therefore important for the physician to be aware of the possibility of both iatrogenic and factitious Cushing's syndrome. Although most common with oral therapy, it is also important to be alert to the fact that all forms of glucocorticoid delivery have the potential to cause Cushing's syndrome. Withdrawal from chronic glucocorticoid therapy presents significant challenges. These include the possibility of adrenal insufficiency after discontinuation of steroid therapy, recurrence of underlying disease as the glucocorticoid is being withdrawn, and the possibility of steroid withdrawal symptoms. Nonetheless, with patience and persistence, a reasonable approach to withdrawal of glucocorticoid therapy can be achieved.

  16. Amphetamine and antidepressant drug effects on GABA- and NMDA-related seizures. (United States)

    Borowski, T B; Kirkby, R D; Kokkinidis, L


    Research has shown a synergistic relationship between amphetamine sensitization and limbic system kindling. To explore the role of GABA and NMDA receptor activity in modulating the positive effects of amphetamine on epileptogenesis, alterations in GABA- and NMDA-related convulsions were examined after acute and chronic amphetamine administration. A single injection of d-amphetamine (7.5 mg/kg) significantly decreased latencies to generalized motor seizures induced 12 h later by the noncompetitive GABAA receptor antagonist picrotoxin (10 mg/kg). The increased sensitivity to clonus was specific to acute amphetamine treatment and was not evident following withdrawal from chronic drug exposure. Seizures induced by NMDLA (1,000 mg/kg), on the other hand, were not modified by acute amphetamine injection; however, the latency to clonus was reduced substantially after NMDLA injection to mice chronically preexposed to amphetamine. The short- and long-term amphetamine effects on GABA- and NMDA-associated convulsive activity were not paralleled by similar drug treatment schedules involving acute (20 mg/kg) and chronic administration of desipramine, zimelidine, and buproprion. These results suggest that amphetamine may be acting on inhibitory and excitatory amino acid systems independently of its monoaminergic properties. The implications of these findings were discussed in relation to amphetamine sensitization of mesolimbic functioning.

  17. Dissociation in patients with dissociative seizures: relationships with trauma and seizure symptoms. (United States)

    Pick, S; Mellers, J D C; Goldstein, L H


    This study aimed to extend the current understanding of dissociative symptoms experienced by patients with dissociative (psychogenic, non-epileptic) seizures (DS), including psychological and somatoform types of symptomatology. An additional aim was to assess possible relationships between dissociation, traumatic experiences, post-traumatic symptoms and seizure manifestations in this group. A total of 40 patients with DS were compared with a healthy control group (n = 43), matched on relevant demographic characteristics. Participants completed several self-report questionnaires, including the Multiscale Dissociation Inventory (MDI), Somatoform Dissociation Questionnaire-20, Traumatic Experiences Checklist and the Post-Traumatic Diagnostic Scale. Measures of seizure symptoms and current emotional distress (Hospital Anxiety and Depression Scale) were also administered. The clinical group reported significantly more psychological and somatoform dissociative symptoms, trauma, perceived impact of trauma, and post-traumatic symptoms than controls. Some dissociative symptoms (i.e. MDI disengagement, MDI depersonalization, MDI derealization, MDI memory disturbance, and somatoform dissociation scores) were elevated even after controlling for emotional distress; MDI depersonalization scores correlated positively with trauma scores while seizure symptoms correlated with MDI depersonalization, derealization and identity dissociation scores. Exploratory analyses indicated that somatoform dissociation specifically mediated the relationship between reported sexual abuse and DS diagnosis, along with depressive symptoms. A range of psychological and somatoform dissociative symptoms, traumatic experiences and post-traumatic symptoms are elevated in patients with DS relative to healthy controls, and seem related to seizure manifestations. Further studies are needed to explore peri-ictal dissociative experiences in more detail.

  18. Magnetic resonance imaging in complex partial seizures

    Furune, Sunao; Negoro, Tamiko; Maehara, Mitsuo; Nomura, Kazushi; Miura, Kiyokuni; Takahashi, Izumi; Watanabe, Kazuyoshi


    Magnetic resonance imaging (MRI) and computed tomography (CT) were performed on 45 patients with intractable complex partial seizures. MRI was performed with a superconducting whole-body scanner operating at 0.5 tesla (T) and 1.5 T. In patients with temporal lobe epilepsy, 8 of 24 patients had abnormal CT, but 16 or 24 patients showed abnormal MRI. 1.5 T MRI detected more abnormality than 0.5 T MRI when CT was normal. In patients with frontal lobe epilepsy, 5 of 7 patients had normal CT and MRI. In 2 other patients, MRI demonstrated an arachnoid cyst and increased signal intensity area on the T2-weighted images which were not detected by CT. In patients with occipital lobe epilepsy, 5 of 6 patients show abnormal CT and MRI. In patients with tuberous sclerosis, MRI revealed some increased signal intensity areas on the T2-weighted images in the occipital and temporal lobe, which were not detected by CT. Most surface EEG foci corresponded with the side of MRI abnormality. These data indicate that MRI is more informative than CT in complex partial seizures. MRI is the imaging technique of choice in the diagnosis of complex partial seizures. (author)

  19. Fluorocitrate-mediated astroglial dysfunction causes seizures. (United States)

    Willoughby, John O; Mackenzie, Lorraine; Broberg, Marita; Thoren, Anna E; Medvedev, Andrei; Sims, Neil R; Nilsson, Michael


    A role for astroglia in epileptogenesis has been hypothesised but is not established. Low doses of fluorocitrate specifically and reversibly disrupt astroglial metabolism by blocking aconitase, an enzyme integral to the tricarboxylic acid cycle. We used cerebral cortex injections of fluorocitrate, at a dose that we demonstrated to inhibit astroglial metabolism selectively, to determine whether astroglial disturbances lead to seizures. Rats were halothane-anesthetized, and 0.8 nmol of sodium fluorocitrate was injected into the cerebral cortex. Extradural electroencephalogram (EEG) electrodes were implanted, after which the anesthesia was ceased and the animals were observed. In all experiments, 14 of 15 fluorocitrate-treated animals exhibited epileptiform EEG discharges, with some animals exhibiting convulsive seizures. Discharges commenced as early as 30 min postfluorocitrate injection. Intraperitoneal octanol, but not halothane by inhalation, given to test the possible participation of gap junctions in EEG discharge generation, blocked or delayed the occurrence of discharges after fluorocitrate. These results indicate that focal cerebrocortical astroglial dysfunction leads to focal epileptiform discharges and sometimes to convulsive seizures and that the process possibly depends on effects mediated by gap junctions.

    Masoumeh Seghatoleslam


    Full Text Available Nigella sativa (NS has been suggested to have neuroprotective and anti-seizures properties. The aim of current study was to investigate the effects of NS hydro-alcoholic extract on neural damage after pentylenetetrazole (PTZ – induced repeated seizures. The rats were divided into five groups: (1 control (saline, (2 PTZ (50 mg/kg, i.p., (3–5 PTZ-NS 100, PTZ-NS 200 and PTZ-NS 400 (100, 200 and 400 mg/kg of NS extract respectively, 30 min prior to each PTZ injection on 5 consecutive days. The passive avoidance (PA test was done and the brains were then removed for histological measurements. The PTZ-NS 100, PTZ-NS 200 and PTZ-NS 400 groups had lower seizure scores than PTZ group (P < 0.01 and P < 0.001. The latency to enter the dark compartment by the animals of PTZ group was lower than control in PA test (P < 0.01. Pre-treatment by 400 mg/kg of the extract increased the latency to enter the dark compartment (P < 0.05. Meanwhile, different doses of the extract inhibited production of dark neurons in different regions of hippocampus (P < 0.001. The present study allows us to suggest that the NS possesses a potential ability to prevent hippocampal neural damage which is accompanied with improving effects on memory.

  1. [Psychiatric disorders induced by drug dependence other than alcohol]. (United States)

    Lejoyeux, M; Mourad, I; Ades, J


    Most of psychoactive substances abuse or dependence disorders are associated to another psychiatric disorders. Depression, anxiety and psychotic disorders are the more frequent comorbid disorders. Psychiatric comorbidity is induced by acute consumption of psychoactive agents, chronic consumption or withdrawal. Psychiatric disorders are more frequent when patient are assessed immediately after the withdrawal. Main biological factors implicated in the pathophysiology of psychiatric disorders associated to dependence disorders are: increase in norepinephrine activity, during withdrawal, activation of locus coeruleus, kinding induced by repeated withdrawals. Psychotic disorders in opiate dependent patients can be induced by withdrawals. These psychotic disorders are more often described after methadone discontinuation. Consumption of cocaine can provocate paranoid delusions. Phenylcyclidine provocates sensorial distortion or delusive disorders resembling schizophrenia. Flash backs, following withdrawal realized brief and transient psychotic disorders. They can occur up to one year after the end of the intoxication. The occurrence of depression in dependent patients is frequent. Depressed patients are at risk for suicide. Retrospective studies showed that near of 40% of the subjects died from suicide have presented alcohol or drug abuse or dependence. Withdrawal from opiates provocates depression. Clinical picture included apathy, blunting of the affects, sadness and loss of interest. Cocaine consumption provocates manic-like disinhibition at the beginning of the intoxication. Long term consumption and withdrawal increase the risk of depression.

  2. Characterization of early partial seizure onset: frequency, complexity and entropy. (United States)

    Jouny, Christophe C; Bergey, Gregory K


    A clear classification of partial seizures onset features is not yet established. Complexity and entropy have been very widely used to describe dynamical systems, but a systematic evaluation of these measures to characterize partial seizures has never been performed. Eighteen different measures including power in frequency bands up to 300 Hz, Gabor atom density (GAD), Higuchi fractal dimension (HFD), Lempel-Ziv complexity, Shannon entropy, sample entropy, and permutation entropy, were selected to test sensitivity to partial seizure onset. Intracranial recordings from 45 patients with mesial temporal, neocortical temporal and neocortical extratemporal seizure foci were included (331 partial seizures). GAD, Lempel-Ziv complexity, HFD, high frequency activity, and sample entropy were the most reliable measures to assess early seizure onset. Increases in complexity and occurrence of high-frequency components appear to be commonly associated with early stages of partial seizure evolution from all regions. The type of measure (frequency-based, complexity or entropy) does not predict the efficiency of the method to detect seizure onset. Differences between measures such as GAD and HFD highlight the multimodal nature of partial seizure onsets. Improved methods for early seizure detection may be achieved from a better understanding of these underlying dynamics. Copyright © 2011 International Federation of Clinical Neurophysiology.

  3. Hyperglycemia associated with seizure control in status epilepticus. (United States)

    Chiewthanakul, Piyawan; Noppaklao, Parinya; Sawanyawisuth, Kittisak; Tiamkao, Somsak


    Status epilepticus (SE) is a serious neurological condition and has a high mortality rate. Factors associated with seizure control measures in nonneurointensive care units (non-NICU) are limited. Adult patients diagnosed with SE at Khon Kaen hospital, Thailand from October 1st, 2010 to September 30th, 2012 were enrolled. Patients were categorized as having controlled seizures and having uncontrolled seizures. Controlled seizures were defined as seizures that were aborted without any recurrence, while uncontrolled seizures were defined as unstoppable or recurrent seizures. Clinical factors were analyzed to find factors associated with uncontrolled SE. During the study period, there were 211 patients diagnosed with SE. Of those, 57 patients (27.01%) were in the group with controlled SE. Plasma glucose and serum albumin were two significant factors with adjusted ORs (95% CI) of 1.008 (1.001, 1.027) and 0.166 (0.059, 0.466) that differentiated patients with controlled seizures from patients with uncontrolled seizures. Central nervous system infections and cardiac arrests were also completely associated with the uncontrolled SE in the multivariate logistic analysis. In the etiology of SE, high plasma glucose and low serum albumin levels were associated with uncontrolled seizures in patients with SE in the non-NICU setting.

  4. Epileptic seizures in patients with a posterior circulation infarct

    Directory of Open Access Journals (Sweden)

    Yüksel Kaplan


    Full Text Available OBJECTIVE: The aim of this study was to investigate the frequency of seizures and the clinical features of patients with seizures related to a posterior circulation infarct (POCI. METHODS: We reviewed all ischemic stroke patients admitted to our clinic between January 2011 and January 2012. The patients’ database information was retrospectively analyzed. Fifty-five patients with a POCI were included in the study. We reviewed all patients with epileptic seizures related to a POCI. Age, gender, recurrent stroke, risk factors, etiology, radiographic localization, the seizure type and onset time, and the electroencephalographic findings of patients were evaluated. We excluded all patients who had precipitating conditions during seizures such as taking drugs, acid-base disturbances, electrolyte imbalance, and history of epilepsy. RESULTS: Seizures were observed in four patients (3 male, 1 female with a POCI related epileptic seizures (7.2%. The etiology of strokes was cardiac-embolic in 3 patients and vertebral artery dissection in 1 patient. Seizures occurred in 2 patients as presenting finding, in 1 patient within 7 days, and 1 patient within 28 days. Primary generalized tonic-clonic seizures occurred in 3 patients and simple partial seizures with secondary generalization in 1 patient. Three patients had cerebellum infarction at the left hemisphere. One patient had lateral medullary infarction at the right side. The electroencephalographic findings of patients were normal. CONCLUSION: Studies involving patients with seizures related to a POCI are novel and few in number. Three patients with seizure had cerebellum infarction. The cerebellum in these patients may contribute via different mechanisms over seizure activity.

  5. Serotonergic activity and hypothalamic-pituitary-adrenal axis response in alcohol administered and subsequently withdrawn rats. (United States)

    Ara, Iffat; Bano, Samina


    Present study aims to depict the role of serotonergic pathways in discrete brain areas (hypothalamus, amygdala, and hippocampus) and their interaction with hypothalamic pituitary adrenal (HPA) axis in alcohol dependence and subsequent withdrawal syndrome in rats. Albino Wistar rats were fed a liquid diet containing alcohol for 4 weeks. Matched control rats were fed isocaloric amounts of the alcohol-free liquid diet, in which the alcohol contribution was substituted with maltose-dextrin. Brain regional tryptophan, 5-hydroxytryptamine (5-HT), 5-Hydroxyindoleacetic acid (5-HIAA) concentrations were determined using high performance liquid chromatography with flourimetric detector. Serum corticosterone was determined spectrofluorimetrically. Data analysis showed that there was significant increase in tryptophan (hippocampus), 5-HT (hippocampus and amygdala) and 5-HT turnover in all the three regions examined when alcohol administered rats were compared with matched controls. In contrast withdrawal from alcohol decreased brain tryptophan, 5-HT and its turnover. It is concluded that the prolong alcohol use boost functions of serotonergic neuronal pathways, in particular, hypothalamus that regulate HPA-axis function and develop tolerance and adaptation. In addition, withdrawal from alcohol exacerbates serotonergic functions that results in failure to suppress corticosterone levels and hence induce low mood states and other signs and symptoms of alcohol withdrawal syndrome.

  6. Administration of memantine during ethanol withdrawal in neonatal rats: effects on long-term ethanol-induced motor incoordination and cerebellar Purkinje cell loss. (United States)

    Idrus, Nirelia M; McGough, Nancy N H; Riley, Edward P; Thomas, Jennifer D


    Alcohol consumption during pregnancy can damage the developing fetus, illustrated by central nervous system dysfunction and deficits in motor and cognitive abilities. Binge drinking has been associated with an increased risk of fetal alcohol spectrum disorders, likely due to increased episodes of ethanol withdrawal. We hypothesized that overactivity of the N-methyl-D-aspartate (NMDA) receptor during ethanol withdrawal leads to excitotoxic cell death in the developing brain. Consistent with this, administration of NMDA receptor antagonists (e.g., MK-801) during withdrawal can attenuate ethanol's teratogenic effects. The aim of this study was to determine whether administration of memantine, an NMDA receptor antagonist, during ethanol withdrawal could effectively attenuate ethanol-related deficits, without the adverse side effects associated with other NMDA receptor antagonists. Sprague-Dawley pups were exposed to 6.0 g/kg ethanol or isocaloric maltose solution via intubation on postnatal day 6, a period of brain development equivalent to a portion of the 3rd trimester. Twenty-four and 36 hours after ethanol, subjects were injected with 0, 10, or 15 mg/kg memantine, totaling doses of 0, 20, or 30 mg/kg. Motor coordination was tested on a parallel bar task and the total number of cerebellar Purkinje cells was estimated using unbiased stereology. Alcohol exposure induced significant parallel bar motor incoordination and reduced Purkinje cell number. Memantine administration significantly attenuated both ethanol-associated motor deficits and cerebellar cell loss in a dose-dependent manner. Memantine was neuroprotective when administered during ethanol withdrawal. These data provide further support that ethanol withdrawal contributes to fetal alcohol spectrum disorders.

  8. The current situation of treatment systems for alcoholism in Korea. (United States)

    Kim, Jee Wook; Lee, Boung Chul; Kang, Tae-Cheon; Choi, Ihn-Geun


    Alcoholism is becoming one of the most serious issues in Korea. The purpose of this review article was to understand the present status of the treatment system for alcoholism in Korea compared to the United States and to suggest its developmental direction in Korea. Current modalities of alcoholism treatment in Korea including withdrawal treatment, pharmacotherapy, and psychosocial treatment are available according to Korean evidence-based treatment guidelines. Benzodiazepines and supportive care including vitamin and nutritional support are mainly used to treat alcohol withdrawal in Korea. Naltrexone and acamprosate are the drugs of first choice to treat chronic alcoholism. Psychosocial treatment methods such as individual psychotherapy, group psychotherapy, family therapy, cognitive behavior therapy, cue exposure therapy, 12-step facilitation therapy, self-help group therapy, and community-based treatment have been carried out to treat chronic alcoholism in Korea. However, current alcohol treatment system in Korea is not integrative compared to that in the United States. To establish the treatment system, it is important to set up an independent governmental administration on alcohol abuse, to secure experts on alcoholism, and to conduct outpatient alcoholism treatment programs and facilities in an open system including some form of continuing care.

  9. Subjective and objective characteristics of altered consciousness during epileptic seizures. (United States)

    Campora, Nuria; Kochen, Silvia


    Conscious states are inner states and processes of awareness. These states are by definition subjective. We analyzed subjective and objective characteristics of alteration of consciousness (AOC) during epileptic seizures, including its involvement in both the level of awareness and subjective content of consciousness. We evaluated AOC using the Consciousness Seizure Scale, the Ictal Consciousness Inventory, and a new structured survey developed by our group: the Seizure Perception Survey, which incorporates patients' subjective experiences before and after they watch a video-electroencephalographic recording of their own seizure. We included 35 patients (105 seizures) with drug-resistant epilepsy. Most seizures caused profound AOC. The content of consciousness was lower during temporal seizures with profound AOC. We uncovered a correlation between the subjective perception and objective duration of a seizure using the Seizure Perception Survey regarding memory; the patients had a better recall of ictal onset during wakefulness regardless of the epileptogenic zone, laterality, or magnitude of AOC. Nonetheless, the recovery of memory at the end of a seizure took more time in patients who showed greater AOC, less vivid content of consciousness, or a longer seizure. For 85% of the patients, this was the first time they were able to view their own seizures. The majority of the patients requested to view them again because this procedure allowed them to compare the recordings with their own memories and emotions during a seizure and to verify the real duration of the seizure. Alteration of consciousness is one of the most dramatic clinical manifestations of epilepsy. Usually, practitioners or relatives assume that the patients with AOC may not have any knowledge on their seizures. In this study, however, we found that most patients with AOC had a fairly accurate perception of the duration of a seizure and retained their memory of ictal onset. In contrast, for the

  10. Minimum Electric Field Exposure for Seizure Induction with Electroconvulsive Therapy and Magnetic Seizure Therapy. (United States)

    Lee, Won H; Lisanby, Sarah H; Laine, Andrew F; Peterchev, Angel V


    Lowering and individualizing the current amplitude in electroconvulsive therapy (ECT) has been proposed as a means to produce stimulation closer to the neural activation threshold and more focal seizure induction, which could potentially reduce cognitive side effects. However, the effect of current amplitude on the electric field (E-field) in the brain has not been previously linked to the current amplitude threshold for seizure induction. We coupled MRI-based E-field models with amplitude titrations of motor threshold (MT) and seizure threshold (ST) in four nonhuman primates (NHPs) to determine the strength, distribution, and focality of stimulation in the brain for four ECT electrode configurations (bilateral, bifrontal, right-unilateral, and frontomedial) and magnetic seizure therapy (MST) with cap coil on vertex. At the amplitude-titrated ST, the stimulated brain subvolume (23-63%) was significantly less than for conventional ECT with high, fixed current (94-99%). The focality of amplitude-titrated right-unilateral ECT (25%) was comparable to cap coil MST (23%), demonstrating that ECT with a low current amplitude and focal electrode placement can induce seizures with E-field as focal as MST, although these electrode and coil configurations affect differently specific brain regions. Individualizing the current amplitude reduced interindividual variation in the stimulation focality by 40-53% for ECT and 26% for MST, supporting amplitude individualization as a means of dosing especially for ECT. There was an overall significant correlation between the measured amplitude-titrated ST and the prediction of the E-field models, supporting a potential role of these models in dosing of ECT and MST. These findings may guide the development of seizure therapy dosing paradigms with improved risk/benefit ratio.

  12. Comparing maximum autonomic activity of psychogenic non-epileptic seizures and epileptic seizures using heart rate variability. (United States)

    Jeppesen, Jesper; Beniczky, Sándor; Johansen, Peter; Sidenius, Per; Fuglsang-Frederiksen, Anders


    The semiology of psychogenic non-epileptic seizures (PNES) can resemble epileptic seizures, and differentiation between epileptic seizures with no EEG-correlate and PNES can be challenging even for trained experts. Therefore, there has been a search for a quantitative measure, other than EEG and semiology that could distinguish PNES from epileptic seizures. We used ECG to measure heart rate variability (HRV) in order to compare maximum autonomic activity of epileptic seizures and PNES. These comparisons could potentially serve as biomarkers for distinguishing these types of clinical episodes. Forty-nine epileptic seizures from 17 patients and 24 PNES from 7 patients with analyzable ECG were recorded during long-term video-EEG monitoring. Moving windows of 100 R-R intervals throughout each seizure were used to find maximum values of Cardiac Sympathetic Index (CSI) (sympathetic tonus) and minimum values of Cardiac Vagal Index (CVI), Root-Mean-Square-of-Successive-Differences (RMSSD) and HF-power (parasympathetic tonus). In addition, non-seizure recordings of each patient were used to compare HRV-parameters between the groups. The maximum CSI for epilepsy seizures were higher than PNES (P=0.015). The minimum CVI, minimum RMSSD and HF-power did not show significant difference between epileptic seizures and PNES (P=0.762; P=0.152; P=0.818). There were no statistical difference of non-seizure HRV-parameters between the PNES and epilepsy patients. We found the maximum sympathetic activity accompanying the epileptic seizures to be higher, than that during the PNES. However, the great variation of autonomic response within both groups makes it difficult to use these HRV-measures as a sole measurement in distinguishing epileptic seizures from PNES.

  13. Designing Patient-Specific Optimal Neurostimulation Patterns for Seizure Suppression. (United States)

    Sandler, Roman A; Geng, Kunling; Song, Dong; Hampson, Robert E; Witcher, Mark R; Deadwyler, Sam A; Berger, Theodore W; Marmarelis, Vasilis Z


    Neurostimulation is a promising therapy for abating epileptic seizures. However, it is extremely difficult to identify optimal stimulation patterns experimentally. In this study, human recordings are used to develop a functional 24 neuron network statistical model of hippocampal connectivity and dynamics. Spontaneous seizure-like activity is induced in silico in this reconstructed neuronal network. The network is then used as a testbed to design and validate a wide range of neurostimulation patterns. Commonly used periodic trains were not able to permanently abate seizures at any frequency. A simulated annealing global optimization algorithm was then used to identify an optimal stimulation pattern, which successfully abated 92% of seizures. Finally, in a fully responsive, or closed-loop, neurostimulation paradigm, the optimal stimulation successfully prevented the network from entering the seizure state. We propose that the framework presented here for algorithmically identifying patient-specific neurostimulation patterns can greatly increase the efficacy of neurostimulation devices for seizures.

  14. Seizure semiology of anti-LGI1 antibody encephalitis. (United States)

    Beimer, Nicholas J; Selwa, Linda M


    Limbic encephalitis associated with anti-LGI1 antibody (LGI1 encephalitis) presents with a variety of features, the most prominent of which include seizures and progressive disturbance of memory and behaviour. Although varied in semiology, recognition of the pattern of seizures in LGI1 encephalitis is important, as early diagnosis and definitive treatment may prevent subsequent development of cognitive impairment. We present a patient with LGI1 encephalitis and "faciobrachial dystonic seizures-plus", which began as classic faciobrachial dystonic seizures and progressed to focal seizures with impaired awareness, dacrystic/gelastic-like outbursts, ictal speech, manual automatisms, and autonomic signs (tachycardia). Recognition of the broad range of seizure types associated with LGI1 encephalitis is crucial for early diagnosis and definitive treatment. [Published with video sequence on].

  15. Antiepileptic drug-induced bone loss in young male patients who have seizures. (United States)

    Andress, Dennis L; Ozuna, Judy; Tirschwell, David; Grande, Lucinda; Johnson, Meshell; Jacobson, Arnold F; Spain, William


    Long-term antiepileptic drug (AED) therapy is a known risk factor for bone loss and fractures. Vitamin D deficiency is frequently cited as a cause for bone loss in patients who have seizures. To determine whether men who have seizures, but who are otherwise healthy, suffer substantial bone loss in the hip while taking AEDs. We prospectively examined femoral neck bone mineral density (BMD) by dual-energy x-ray absorptiometry in 81 consecutive men, aged between 25 and 54 years old (mean age, 45 years), who were attending an outpatient seizure clinic. Low BMD values were analyzed for known risk factors for bone loss. Dual-energy x-ray absorptiometry scans were repeated in 54 patients, 12 to 29 months later (mean, 19 months), to assess the rate of change in BMD over time. Multivariate linear regression analysis revealed that age (P<.001) and time receiving AEDs (P<.003) were the 2 important risk factors associated with low femoral neck BMD. Neither vitamin D deficiency, hypogonadism, cigarette smoking, nor excess alcohol intake were associated with low BMD after correcting for age and time on AEDs. Longitudinal analysis of femoral neck BMD revealed that only those in the youngest age group (25-44 years) showed significant declines in femoral neck BMD (1.8% annualized loss; 95% confidence interval, -3.1 to -0.9; P<.003) while receiving AED therapy. There was no evidence that a specific type of AED was more causally related to bone loss in this group although most patients were taking phenytoin sodium or carbamazepine during the longitudinal assessment. Long-term AED therapy in young male patients who have seizures causes significant bone loss at the hip in the absence of vitamin D deficiency. Dual-energy x-ray absorptiometry scanning of the hip is useful in identifying patients who are particularly susceptible to rapid bone loss while taking AEDs.

  16. Seizure-specific wavelet (Seizlet) design for epileptic seizure detection using CorrEntropy ellipse features based on seizure modulus maximas patterns. (United States)

    Behnam, Morteza; Pourghassem, Hossein


    EEG signal analysis of pediatric patients plays vital role for making a decision to intervene in presurgical stages. In this paper, an offline seizure detection algorithm based on definition of a seizure-specific wavelet (Seizlet) is presented. After designing the Seizlet, by forming cone of influence map of the EEG signal, four types of layouts are analytically designed that are called Seizure Modulus Maximas Patterns (SMMP). By mapping CorrEntropy Induced Metric (CIM) series, four structural features based on least square estimation of fitted non-tilt conic ellipse are extracted that are called CorrEntropy Ellipse Features (CEF). The parameters of the SMMP and CEF are tuned by employing a hybrid optimization algorithm based on honeybee hive optimization in combination with Las Vegas randomized algorithm and Elman recurrent classifier. Eventually, the optimal features by AdaBoost classifiers in a cascade structure are classified into the seizure and non-seizure signals. The proposed algorithm is evaluated on 844h signals with 163 seizure events recorded from 23 patients with intractable seizure disorder and accuracy rate of 91.44% and false detection rate of 0.014 per hour are obtained by 7-channel EEG signals. To overcome the restrictions of general kernels and wavelet coefficient-based features, we designed the Seizlet as an exclusive kernel of seizure signal for first time. Also, the Seizlet-based patterns of EEG signals have been modeled to extract the seizure. The reported results demonstrate that our proposed Seizlet is effectiveness to extract the patterns of the epileptic seizure. Copyright © 2016 Elsevier B.V. All rights reserved.

  2. Psychogenic non-epileptic seizures: our video-EEG experience. (United States)

    Nežádal, Tomáš; Hovorka, Jiří; Herman, Erik; Němcová, Iveta; Bajaček, Michal; Stichová, Eva


    The aim of our study was to assess the number of psychogenic non-epileptic seizures (PNES) in our patients with a refractory seizure disorder, to determine the 'typical' PNES semiology using video-EEG monitoring and describe other PNES parameters. We evaluated prospectively 596 patients with pharmacoresistant seizures. All these patients underwent continuous video-EEG monitoring. In consenting patients, we used suggestive seizure provocation. We assessed seizure semiology, interictal EEG, brain MRI, psychiatric co-morbidities, personality profiles, and seizure outcome. In the sample of 596 monitored patients, we detected 111 (19.3%) patients with PNES. Of the 111 patients with PNES, 86.5% had spontaneous and 76.5% had provoked seizures. The five most typical symptoms were: initially closed eyelids (67.6%), rapid tremor (47.7%), asynchronous limb movement (37.8%), preictal pseudosleep (33.3%), and side-to-side head movement (32.4%). Interictal EEG was rated as abnormal in 46.2% and with epileptiform abnormality in 9%. Brain MRI was abnormal in 32 (28.8%) patients. Personality disorders (46.8%), anxiety (39.6%), and depression (12.6%) were the most frequent additional psychiatric co-morbidities. PNES outcome after at least 2 years is reported; 22.5% patients was seizure-free; one-third had markedly reduced seizure frequency. We have not seen any negative impact of the provocative testing on the seizure outcome. Video-EEG monitoring with suggestive seizure provocation supported by clinical psychiatric and psychological evaluation significantly contributes to the correct PNES diagnosis, while interictal EEG and brain MRI are frequently abnormal. Symptoms typical for PNES, as opposed to epileptic seizures, could be distinguished.

  3. Consciousness and epilepsy: why are complex-partial seizures complex? (United States)

    Englot, Dario J; Blumenfeld, Hal


    Why do complex-partial seizures in temporal lobe epilepsy (TLE) cause a loss of consciousness? Abnormal function of the medial temporal lobe is expected to cause memory loss, but it is unclear why profoundly impaired consciousness is so common in temporal lobe seizures. Recent exciting advances in behavioral, electrophysiological, and neuroimaging techniques spanning both human patients and animal models may allow new insights into this old question. While behavioral automatisms are often associated with diminished consciousness during temporal lobe seizures, impaired consciousness without ictal motor activity has also been described. Some have argued that electrographic lateralization of seizure activity to the left temporal lobe is most likely to cause impaired consciousness, but the evidence remains equivocal. Other data correlates ictal consciousness in TLE with bilateral temporal lobe involvement of seizure spiking. Nevertheless, it remains unclear why bilateral temporal seizures should impair responsiveness. Recent evidence has shown that impaired consciousness during temporal lobe seizures is correlated with large-amplitude slow EEG activity and neuroimaging signal decreases in the frontal and parietal association cortices. This abnormal decreased function in the neocortex contrasts with fast polyspike activity and elevated cerebral blood flow in limbic and other subcortical structures ictally. Our laboratory has thus proposed the "network inhibition hypothesis," in which seizure activity propagates to subcortical regions necessary for cortical activation, allowing the cortex to descend into an inhibited state of unconsciousness during complex-partial temporal lobe seizures. Supporting this hypothesis, recent rat studies during partial limbic seizures have shown that behavioral arrest is associated with frontal cortical slow waves, decreased neuronal firing, and hypometabolism. Animal studies further demonstrate that cortical deactivation and behavioral

  4. Sex-specific consequences of early life seizures. (United States)

    Akman, Ozlem; Moshé, Solomon L; Galanopoulou, Aristea S


    Seizures are very common in the early periods of life and are often associated with poor neurologic outcome in humans. Animal studies have provided evidence that early life seizures may disrupt neuronal differentiation and connectivity, signaling pathways, and the function of various neuronal networks. There is growing experimental evidence that many signaling pathways, like GABAA receptor signaling, the cellular physiology and differentiation, or the functional maturation of certain brain regions, including those involved in seizure control, mature differently in males and females. However, most experimental studies of early life seizures have not directly investigated the importance of sex on the consequences of early life seizures. The sexual dimorphism of the developing brain raises the question that early seizures could have distinct effects in immature females and males that are subjected to seizures. We will first discuss the evidence for sex-specific features of the developing brain that could be involved in modifying the susceptibility and consequences of early life seizures. We will then review how sex-related biological factors could modify the age-specific consequences of induced seizures in the immature animals. These include signaling pathways (e.g., GABAA receptors), steroid hormones, growth factors. Overall, there are very few studies that have specifically addressed seizure outcomes in developing animals as a function of sex. The available literature indicates that a variety of outcomes (histopathological, behavioral, molecular, epileptogenesis) may be affected in a sex-, age-, region-specific manner after seizures during development. Obtaining a better understanding for the gender-related mechanisms underlying epileptogenesis and seizure comorbidities will be necessary to develop better gender and age appropriate therapies.

  5. Forecasting seizures in dogs with naturally occurring epilepsy.

    Directory of Open Access Journals (Sweden)

    J Jeffry Howbert

    Full Text Available Seizure forecasting has the potential to create new therapeutic strategies for epilepsy, such as providing patient warnings and delivering preemptive therapy. Progress on seizure forecasting, however, has been hindered by lack of sufficient data to rigorously evaluate the hypothesis that seizures are preceded by physiological changes, and are not simply random events. We investigated seizure forecasting in three dogs with naturally occurring focal epilepsy implanted with a device recording continuous intracranial EEG (iEEG. The iEEG spectral power in six frequency bands: delta (0.1-4 Hz, theta (4-8 Hz, alpha (8-12 Hz, beta (12-30 Hz, low-gamma (30-70 Hz, and high-gamma (70-180 Hz, were used as features. Logistic regression classifiers were trained to discriminate labeled pre-ictal and inter-ictal data segments using combinations of the band spectral power features. Performance was assessed on separate test data sets via 10-fold cross-validation. A total of 125 spontaneous seizures were detected in continuous iEEG recordings spanning 6.5 to 15 months from 3 dogs. When considering all seizures, the seizure forecasting algorithm performed significantly better than a Poisson-model chance predictor constrained to have the same time in warning for all 3 dogs over a range of total warning times. Seizure clusters were observed in all 3 dogs, and when the effect of seizure clusters was decreased by considering the subset of seizures separated by at least 4 hours, the forecasting performance remained better than chance for a subset of algorithm parameters. These results demonstrate that seizures in canine epilepsy are not randomly occurring events, and highlight the feasibility of long-term seizure forecasting using iEEG monitoring.

  10. AED discontinuation may be dangerous for seizure-free patients. (United States)

    Schmidt, Dieter


    Despite its benefits, stopping antiepileptic drugs (AEDs) in seizure-free patients is associated with several risks. AED discontinuation doubles the risk of seizure recurrence for up to 2 years compared with continued treatment. On average, one in three patients has a seizure recurrence, though the range can go up to 66% (34%, range 12-66%, 95% CI: 27-43). Furthermore, the outcome of treating a seizure recurrence in patients who have been seizure-free for years is surprisingly poor in some patients. Although the long-term prognosis is not worsened by drug discontinuation, one in five patients does not re-enter remission and for some patients, it may take several years to become seizure-free again. The risk of seizure recurrence is particularly high for those with juvenile myoclonic epilepsy and symptomatic focal epilepsy, the most frequent epilepsies in adults. Seizure-recurrence may have devastating, medical, psychological and social consequences for the individual, for example injury, loss of self-esteem, unemployment and losing a driver's license. Discontinuation should be avoided in patients with a high risk of seizure recurrence. Given these risks, patients will ultimately have to decide themselves whether they wish to discontinue drug treatment after full informed consent.

  11. Treatment Outcome Of Seizures Associated With Intracranial Cavernous Angiomas

    Directory of Open Access Journals (Sweden)

    Nievera Conrad C


    Full Text Available Seizures are among the typical presentations of intracranial cavernous angiomas (ICA. Twenty-one patients (age range: 2 to 53 years treated for seizures associated with ICA between 1983 and 1997 were restrospectively studied to evaluate their outcome following medical or surgical intervention. The mean interval between seizure onset and initial presentation at our institution was 7.6 years. Seizures were simple partial in 3 patients, complex partial in 15 and secondarily generalized tonic-clonic in 13. The commonest site of the lesion was the temporal lobe (52%. Multiple angiomas were observed in 5 (24% patients. Seven (32% patients were medically-managed with antiepileptic therapy and 14 (68% underwent either lesionectomy with resection of the epileptogenic zone (9 patients or temporal lobectomy (5 patients. Mean follow-up time was 4 years (range: 3 months to 14 years. Of the medically-managed patients, 3 (43% remained seizure-free whereas 4 (57% continued to have seizures with an average frequency of one per day. Of the surgically-managed patients, 12 (86% became seizure-free and 2 (14% had no more than two seizures per year. Surgery appears to be extremely effective in the management of seizures associated with ICA and should receive a strong and early consideration in patients who fail medical therapy.

  16. [Social aspects of epilepsy: marriage, pregnancy, driving, antiepileptic drug withdrawal and against social stigma]. (United States)

    Tsuji, Sadatoshi


    Persons with epilepsy need adequate advice and effective counselling about issues such as marriage, pregnancy, risks of inheriting epilepsy, driving, employment and antiepileptic drug withdrawal, because these persons are not receiving important information and education about their condition and possible adverse effects of treatment. Furthermore, women with epilepsy have increased rates of pregnancy complications and poor fetal outcomes including congenital malformations and developmental delay related to both their epilepsy and antiepileptic drugs. However, approximately 90% of all women with epilepsy undergo normal pregnancy and give birth to children free of birth defects. Pregnancy is generally safe in women with epilepsy. The study of long-term prognosis of childhood-onset epilepsy in Japan shows that the majority of these patients have lower levels of educational background as well as employment and marital status compared with the general population (Wakamoto H. et al). Of patients with epilepsy, 60% to 70% achieve control with antiepileptic medication. However, several antiepileptic drug withdrawal studies show variable rates of success, with relapse rates ranging from 12% to 63% (Britton J.W.). Driving is listed as major problem in persons with epilepsy. However, the patients with seizure-free more than two years have been able to get the driver's license since June, 2002. Social attitudes towards epilepsy cause more distress to the patient than the disease itself. We should realize that persons with epilepsy are normal or near-normal. To ameliorate the social stigma against epilepsy, continuous and repetitive educational efforts would be needed.

    Sieweke Nicole


    Full Text Available Abstract Background Cardiac troponin-I (cTNI is highly specific biomarker to prove myocardial damage, e.g. in acute coronary syndrome (ACS. However, it occurs in other conditions as well. We therefore analysed cTNI increase in patients after generalized convulsive seizure. Methods Consecutive patients admitted with acute generalized convulsive seizure were included in case of cTNI measurement on admission. Among 898 selected cases, 53 patients were referred secondary to our department; in 845 cases cTNI measurements on admission were available. In case of multiple admissions (81 cases, only the first admission entered our analysis. In 17 patients elevated cTNI was determined due to ACS; in one patient a myocarditis was found. 5 patients suffered of relevant renal insufficiency. Finally 741 patients were included in the analysis. A cTNI cut-off level of ≥ 0.1 ng/ml was considered. Factors associated with a cTNI increase were analysed subsequently. Results The mean age of the study population (n = 741 was 47.8 years (SD ± 18.6, 40.9% were female. In 50 patients (6.7% a cTNI elevation of unknown origin was found; no obvious cardiac involvement could be detected in these patients who all remained asymptomatic. A vascular risk profile (including at least hypertension, hypercholesterolemia or diabetes (OR = 3.62; CI: 1.59 to 8.21; p = 0.001 and elevated creatine kinase on admission (OR = 2.36; CI: 1.26 to 4.39; p = 0.002 were independent factors associated with cTNI release. Conclusion cTNI release occurs in patients with generalized convulsive seizure with predominance in patients with vascular risk profile.

  18. Benign focal epilepsy of childhood with centrotemporal spikes (BECTS: clinical characteristics of seizures according to age at first seizure

    Directory of Open Access Journals (Sweden)

    Miziara Carmen Silvia M.G.


    Full Text Available BECTS is characterized by the presence of simple partial motor seizures in the face and/or oropharynx, with or without sensory symptoms and often with secondary generalization. These seizures tend to occur more often during sleep or drowsiness. According to some authors, generalized seizures prevail over other types particularly among children aged five or less. The purpose of this study is to determine the characteristics of the first epileptic episode among children with BECTS, grouped by age as of their first epileptic seizure, as well as to analyze how such seizures change over the course of clinical evolution. A total of 61 children were examined, 16 of whom below the age of 5 and 45 above. With regard to the first and recurrent epileptic episodes, our final assessment showed that partial seizures occurred more frequently than generalized tonic-clonic seizures in both groups. Although no conclusive relation could be established between the type of partial seizure (i.e. simple versus complex and the children's age as of their first epileptic episode, it was possible to correlate the type of epileptic seizure with their clinical evolution, in which case simple partial seizures proved to be more frequent than complex partial seizures. It should be noted that the number of children under the age of five was relatively small, which evinces the need for further studies. It should also be borne in mind that the reported frequency of generalized seizures in these children's first epileptic episode may be due to their parents' lack of attention and familiarity with this pathology and their attendant difficulty in characterizing its clinical symptoms.

  19. Predictors of long term opioid withdrawal outcome after short-term stabilization with buprenorphine. (United States)

    Saleh, M I


    We aim to examine predictors of opiate abstinence status 3 months after the end of buprenorphine/naloxone treatment for opioid-dependent participants. Participants (n= 516, age > 15 years) received buprenorphine/ naloxone treatment for 4 weeks and then randomly assigned to undergo dose tapering over either 7 days or 28 days. Bivariate analysis was performed to identify possible predictors of successful opiate abstinence outome (p-value opioid and drug urine tests result at the end taper; employment status, family problems, and alcohol use domains of addiction severity index (ASI) score; and clinical opiate withdrawal scale (COWS) at the end of stabilization. Final predictor list identified by logistic regression include: ASI score for family and alcohol problems, COWS at the end of stabilization and opiate urine test at the end of taper. Participants presenting with a negative urine test for opiate, more severe alcohol, more severe family problems, or more symptoms of opiate withdrawal at the end of stabilization were more likely to have a successful opiate abstinence.

  20. Seizure semiology in males with psychogenic nonepileptic seizures is associated with somatic complaints. (United States)

    Gale, Shawn D; Hill, Stacy W; Pearson, Caleb


    Psychopathology has been studied in patients with epileptic or psychogenic non-epileptic seizures in the context of diagnosis and treatment. Unfortunately, most PNES studies include few males and do not consider possible gender differences, making findings less generalizable to males with PNES. In this study we specifically compare males with PNES to females with PNES and to males with epilepsy. Males with PNES (n=58), males with epilepsy (n=86), females with PNES (n=147), and females with ES (n=142) were evaluated on an inpatient epilepsy monitoring unit. Self-reported objective measures of psychopathology, demographics, and PNES seizure semiology were compared. Personality Assessment Inventory profiles revealed marked differences, particularly in somatic symptoms, between PNES and epilepsy. Females with PNES had higher levels of physiological depressive symptoms but lower antisocial features. Males with PNES who had clinically significant elevations on the somatic complaints scale were much more likely to have motor seizures while females with PNES classified similarly were equally likely to have either motor or non-motor events. Gender difference in PNES seizure semiology was associated with whether or not clinically significant somatic symptoms were present; males with elevated somatic symptoms were much more likely to have motor PNES. However, we did not find evidence of greater psychopathology in males with PNES compared to females with PNES. Gender differences in the behavioral manifestation of PNES in the context of presence or absence of somatization may have implications for diagnosis and treatment. Copyright © 2015 Elsevier B.V.

  11. Hemispheric surgery for refractory epilepsy in children and adolescents: outcome regarding seizures, motor skills and adaptive function. (United States)

    Hamad, Ana Paula; Caboclo, Luís Otávio; Centeno, Ricardo; Costa, Livia Vianez; Ladeia-Frota, Carol; Junior, Henrique Carrete; Gomez, Nicolas Garofalo; Marinho, Murilo; Yacubian, Elza Márcia Targas; Sakamoto, Américo Ceiki


    The aim of the study was to report the seizure outcome, motor skills and adaptive motor functions in a series of children and adolescents who underwent hemispheric surgery, analysing the risk-benefits of surgery. The clinical course, seizure and motor function outcomes of 15 patients who underwent hemispheric surgery were reviewed. The mean age at surgery was 9.5, with 1-9 years follow-up. The underlying pathologies were Rasmussen encephalitis, vascular disorders, and hemimegalencephaly. All the patients presented with severe epilepsy and different degrees of hemiparesis, although motor functionality was preserved in 80% of the patients. At last follow-up, 67% were seizure free, and 20% rarely experienced seizures. Antiepileptic drugs were reduced in 60%, and complete withdrawal from such drugs was successful in 20% of the patients. The motor outcome following the surgery varied between the patients. Despite the motor deficit after surgery, the post-operative motor function showed unchanged for gross motor function in most (60%), while 27% improved. Similar results were obtained for the ability to handle objects in daily life activities. Sixty percent of the children were capable of handling objects, with somewhat reduced coordination and/or motor speed. Pre-surgical motor function continues to play a role in the pre-surgical evaluation process in order to provide a baseline for outcome. Hemispheric surgery, once regarded as a radical intervention and last treatment resource, may become routinely indicated for refractory hemispheric epilepsy in children and adolescents, with oftentime favourable motor outcomes.

  12. Diagnosing psychogenic nonepileptic seizures: Video-EEG monitoring, suggestive seizure induction and diagnostic certainty. (United States)

    Popkirov, Stoyan; Jungilligens, Johannes; Grönheit, Wenke; Wellmer, Jörg


    Psychogenic nonepileptic seizures (PNES) can remain undiagnosed for many years, leading to unnecessary medication and delayed treatment. A recent report by the International League Against Epilepsy Nonepileptic Seizures Task Force recommends a staged approach to the diagnosis of PNES (LaFrance, et al., 2013). We aimed to investigate its practical utility, and to apply the proposed classification to evaluate the role of long-term video-EEG monitoring (VEEG) and suggestive seizure induction (SSI) in PNES workup. Using electronic medical records, 122 inpatients (mean age 36.0±12.9years; 68% women) who received the diagnosis of PNES at our epilepsy center during a 4.3-year time period were included. There was an 82.8% agreement between diagnostic certainty documented at discharge and that assigned retroactively using the Task Force recommendations. In a minority of cases, having used the Task Force criteria could have encouraged the clinicians to give more certain diagnoses, exemplifying the Task Force report's utility. Both VEEG and SSI were effective at supporting high level diagnostic certainty. Interestingly, about one in four patients (26.2%) had a non-diagnostic ("negative") VEEG but a positive SSI. On average, this subgroup did not have significantly shorter mean VEEG recording times than VEEG-positive patients. However, VEEG-negative/SSI-positive patients had a significantly lower habitual seizure frequency than their counterparts. This finding emphasizes the utility of SSI in ascertaining the diagnosis of PNES in patients who do not have a spontaneous habitual event during VEEG due to, for example, low seizure frequency.

  13. Individualized Low-Amplitude Seizure Therapy: Minimizing Current for Electroconvulsive Therapy and Magnetic Seizure Therapy (United States)

    Peterchev, Angel V; Krystal, Andrew D; Rosa, Moacyr A; Lisanby, Sarah H


    Electroconvulsive therapy (ECT) at conventional current amplitudes (800–900 mA) is highly effective but carries the risk of cognitive side effects. Lowering and individualizing the current amplitude may reduce side effects by virtue of a less intense and more focal electric field exposure in the brain, but this aspect of ECT dosing is largely unexplored. Magnetic seizure therapy (MST) induces a weaker and more focal electric field than ECT; however, the pulse amplitude is not individualized and the minimum amplitude required to induce a seizure is unknown. We titrated the amplitude of long stimulus trains (500 pulses) as a means of determining the minimum current amplitude required to induce a seizure with ECT (bilateral, right unilateral, bifrontal, and frontomedial electrode placements) and MST (round coil on vertex) in nonhuman primates. Furthermore, we investigated a novel method of predicting this amplitude-titrated seizure threshold (ST) by a non-convulsive measurement of motor threshold (MT) using single pulses delivered through the ECT electrodes or MST coil. Average STs were substantially lower than conventional pulse amplitudes (112–174 mA for ECT and 37.4% of maximum device amplitude for MST). ST was more variable in ECT than in MST. MT explained 63% of the ST variance and is hence the strongest known predictor of ST. These results indicate that seizures can be induced with less intense electric fields than conventional ECT that may be safer; efficacy and side effects should be evaluated in clinical studies. MT measurement could be a faster and safer alternative to empirical ST titration for ECT and MST. PMID:25920013

  14. Attention-deficit/hyperactivity disorder medication and seizures. (United States)

    Wiggs, Kelsey K; Chang, Zheng; Quinn, Patrick D; Hur, Kwan; Gibbons, Robert; Dunn, David; Brikell, Isabell; Larsson, Henrik; D'Onofrio, Brian M


    Individuals with attention-deficit/hyperactivity disorder (ADHD) are at increased risk of seizures, but there is uncertainty about whether ADHD medication treatment increases risk among patients with and without preexisting seizures. We followed a sample of 801,838 patients with ADHD who had prescribed drug claims from the Truven Health MarketScan Commercial Claims and Encounters databases to examine whether ADHD medication increases the likelihood of seizures among ADHD patients with and without a history of seizures. First, we assessed overall risk of seizures among patients with ADHD. Second, within-individual concurrent analyses assessed odds of seizure events during months when a patient with ADHD received ADHD medication compared with when the same individual did not, while adjusting for antiepileptic medications. Third, within-individual long-term analyses examined odds of seizure events in relation to the duration of months over the previous 2 years patients received medication. Patients with ADHD were at higher odds for any seizure compared with non-ADHD controls (odds ratio [OR] = 2.33, 95% confidence interval [CI] = 2.24-2.42 males; OR = 2.31, 95% CI = 2.22-2.42 females). In adjusted within-individual comparisons, ADHD medication was associated with lower odds of seizures among patients with (OR = 0.71, 95% CI = 0.60-0.85) and without (OR = 0.71, 95% CI = 0.62-0.82) prior seizures. Long-term within-individual comparisons suggested no evidence of an association between medication use and seizures among individuals with (OR = 0.87, 95% CI = 0.59-1.30) and without (OR = 1.01, 95% CI = 0.80-1.28) a seizure history. Results reaffirm that patients with ADHD are at higher risk of seizures. However, ADHD medication was associated with lower risk of seizures within individuals while they were dispensed medication, which is not consistent with the hypothesis that ADHD medication increases risk of seizures. © 2018 American Academy of Neurology.

  15. [Alcoholism at the end of 1980-s and beginning of 2010-s]. (United States)

    V, Nemtsov A; V, Orlov A

    To study the 20-years' clinical alteration and alcoholism basing on the changes in its clinical symptoms and course. The study included 527 alcoholics with formed alcohol withdrawal syndrome: 181 alcoholics were examined in 1988-1990 (Group 1) and 346 alcoholics in 2011-2012 (Group 2). In Group 1, vodka consumption dominated at all stages of alcoholism. Group 2 included 172 alcoholics with the domination of vodka consumption and 174 alcoholics with mixed consumption. It was shown that in comparison with Group 1 (1988-1990 patients) patients from Group 2 (2011-2012) had slower and mild development of alcoholism, especially those in the mixed consumption group. The authors suggest that the change of the clinical pattern in Group 2 was due to the change in the composition of consumed alcoholic beverages.

  17. Impact of alcohol use on thyroid function

    Directory of Open Access Journals (Sweden)

    Yatan Pal Singh Balhara


    Full Text Available Alcohol is one of the commonest illicit psychoactive substances consumed globally and is the world′s third largest risk factor for disease and disability. It has been reported to have multiple effects on the hypothalamo-pituitary-thyroid axis and the functioning of the thyroid gland. It has been reported to cause direct suppression of thyroid function by cellular toxicity, and indirect suppression by blunting thyrotropin-releasing hormone response. It causes a decrease of peripheral thyroid hormones during chronic use and in withdrawal. Alcohol use may also confer some protective effect against thyroid nodularity, goiter, and thyroid cancer. This article presents a review of the clinically relevant effects of alcohol on the functioning of the thyroid gland and also discusses the effect of medication used in treatment of alcohol dependence on thyroid function.

    Spasić Mirjana


    Full Text Available Background. Cavernous angiomas are angiographically occult vascular malformations that are present in 0.4−0.9 % of people, and represent around 5% of all cerebrovascular malformations. They can be single or multiple, and sporadic or familial. The presence of multiple lesions is more frequent in familial cavernomatosis. Ten to 30 % are associated with familial clustering. Case report. We presented the case of a 43-year-old man, admitted to the Emergency Department due to unprovoked seizure during the wide awake and everyday activities. Neurological examination was with no focal signs. A 32-channel standard digital EEG was without any significant changes of normal baseline activity. After sleep deprivation EEG showed multifocal, bilateral and asymmetric polyspikes and sharpwaves activity. Hyperventilation induced generalized epileptiform discharges. MRI scan demonstrated multiple small cavernous angiomas. Neuropsychological testing demonstrated a delayed memory impairment. Neurosurgery treatment was not recommended, and the therapy with valproate 1 250 mg/day had an excellent efficacy with no singnificant adverse effects. Conclusion. This patient considered as a rare case with multiple cavernomatosis highlights the importance of neuroradiological examination in adult patients with the first epileptic seizure but with no focal neurological signs. .

The aim of this study was to study the time from withdrawing life-sustaining treatment to death in patients with severe ischemic or hemorrhagic stroke.Methods: In total, 2,506 patients with stroke admitted to Haukeland University Hospital between 2006 and 2011 were prospectively registered in the Bergen NORSTROKE database. Risk factors, stroke severity, etiology, and blood analyses were registered. Retrospectively, the patients' records were examined to determine the number of days from withdrawing all life-sustaining treatment to death in patients who died from severe stroke during the hospital stay.Results: Life-sustaining treatment was withheld in 50 patients with severe stroke. Median time to death after withdrawing life-sustaining treatment was 4 days, and a quarter lived at least 1 week (range =1–11 days. Cox regression analyses showed that short time from withdrawing life-sustaining treatment to death was associated with high age (Hazard ratio [HR] =1.05, P=0.07, male sex (HR =2.9, P=0.01, high C-reactive protein on admission (HR =1.01, P=0.001, and hemorrhagic stroke (versus ischemic stroke, HR =1.5, P=0.03.Conclusion: One week after withdrawing life-sustaining treatment, a quarter of our patients with severe stroke remained alive. Short time to death was associated with high age, male sex, hemorrhagic stroke, and high C-reactive protein on admittance. Keywords: stroke, withdrawal of life-sustaining treatment, prognosis

  20. Perception of sleep and dreams in alcohol-dependent patients during detoxication and abstinence. (United States)

    Steinig, Jana; Foraita, Ronja; Happe, Svenja; Heinze, Martin


    This study aims to investigate sleep quality and the subjective dream experience in alcohol-dependent patients during withdrawal and abstinence compared with healthy controls. Thirty-seven patients with alcohol dependency and 35 healthy control subjects were asked to fill in several questionnaires and to give information about their subjective sleep and dream experiences. Twelve patients participated in a follow-up interview 4 weeks later. Sleep quality is impaired in alcohol-dependent patients during detoxication, and the subjective dream experience is more negatively toned compared with healthy controls. Both sleep quality and dream experience improves slightly after 4 weeks of abstinence. Patients with alcohol dependency during withdrawal and abstinence dream significantly more often about alcohol. However, none of the abstinent alcohol-dependent patients dreamed about alcohol during withdrawal. This study shows that the subjective sleep and dream quality is strongly impaired in patients with alcohol dependency. Differences in the dream experience between alcohol-dependent patients and healthy controls are in accordance with the continuity hypotheses of dreaming. The hypothesis of dreaming about alcohol as a compensatory effect, however, could not be confirmed.

  1. Seizures and Sleep in the Thalamus: Focal Limbic Seizures Show Divergent Activity Patterns in Different Thalamic Nuclei. (United States)

    Feng, Li; Motelow, Joshua E; Ma, Chanthia; Biche, William; McCafferty, Cian; Smith, Nicholas; Liu, Mengran; Zhan, Qiong; Jia, Ruonan; Xiao, Bo; Duque, Alvaro; Blumenfeld, Hal


    The thalamus plays diverse roles in cortical-subcortical brain activity patterns. Recent work suggests that focal temporal lobe seizures depress subcortical arousal systems and convert cortical activity into a pattern resembling slow-wave sleep. The potential simultaneous and paradoxical role of the thalamus in both limbic seizure propagation, and in sleep-like cortical rhythms has not been investigated. We recorded neuronal activity from the central lateral (CL), anterior (ANT), and ventral posteromedial (VPM) nuclei of the thalamus in an established female rat model of focal limbic seizures. We found that population firing of neurons in CL decreased during seizures while the cortex exhibited slow waves. In contrast, ANT showed a trend toward increased neuronal firing compatible with polyspike seizure discharges seen in the hippocampus. Meanwhile, VPM exhibited a remarkable increase in sleep spindles during focal seizures. Single-unit juxtacellular recordings from CL demonstrated reduced overall firing rates, but a switch in firing pattern from single spikes to burst firing during seizures. These findings suggest that different thalamic nuclei play very different roles in focal limbic seizures. While limbic nuclei, such as ANT, appear to participate directly in seizure propagation, arousal nuclei, such as CL, may contribute to depressed cortical function, whereas sleep spindles in relay nuclei, such as VPM, may interrupt thalamocortical information flow. These combined effects could be critical for controlling both seizure severity and impairment of consciousness. Further understanding of differential effects of seizures on different thalamocortical networks may lead to improved treatments directly targeting these modes of impaired function. SIGNIFICANCE STATEMENT Temporal lobe epilepsy has a major negative impact on quality of life. Previous work suggests that the thalamus plays a critical role in thalamocortical network modulation and subcortical arousal

    Full Text Available Mohammed A ZolalyDepartment of Pediatrics, College of Medicine, Taibah University, Al-Madinah Al-Munawarah, Kingdom of Saudi ArabiaBackground: The purpose of this study was to determine whether seizure susceptibility due to antihistamines is provoked in patients with febrile seizures.Methods: The current descriptive study was carried out from April 2009 to February 2011 in 250 infants and children who visited the Madinah Maternity and Children's Hospital as a result of febrile convulsions. They were divided into two groups according to administration of antihistamines at the onset of fever.Results: Detailed clinical manifestations were compared between patients with and without administration of antihistamines. The time from fever detection to seizure onset was significantly shorter in the antihistamine group than that in the nonantihistamine group, and the duration of seizures was significantly longer in the antihistamine group than in the nonantihistamine group. No significant difference was found in time from fever detection to seizure onset or seizure duration between patients who received a first-generation antihistamine and those who received a second-generation antihistamine.Conclusion: Due to their central nervous system effects, H1 antagonists should not be administered to patients with febrile seizures and epilepsy. Caution should be exercised regarding the use of histamine H1 antagonists in young infants, because these drugs could potentially disturb the anticonvulsive central histaminergic system.Keywords: antihistamine, nonantihistamine, histamine H1 antagonist, febrile seizures

  11. Seizure Prediction and Detection via Phase and Amplitude Lock Values. (United States)

    Myers, Mark H; Padmanabha, Akshay; Hossain, Gahangir; de Jongh Curry, Amy L; Blaha, Charles D


    A robust seizure prediction methodology would enable a "closed-loop" system that would only activate as impending seizure activity is detected. Such a system would eliminate ongoing stimulation to the brain, thereby eliminating such side effects as coughing, hoarseness, voice alteration, and paresthesias (Murphy et al., 1998; Ben-Menachem, 2001), while preserving overall battery life of the system. The seizure prediction and detection algorithm uses Phase/Amplitude Lock Values (PLV/ALV) which calculate the difference of phase and amplitude between electroencephalogram (EEG) electrodes local and remote to the epileptic event. PLV is used as the seizure prediction marker and signifies the emergence of abnormal neuronal activations through local neuron populations. PLV/ALVs are used as seizure detection markers to demarcate the seizure event, or when the local seizure event has propagated throughout the brain turning into a grand-mal event. We verify the performance of this methodology against the "CHB-MIT Scalp EEG Database" which features seizure attributes for testing. Through this testing, we can demonstrate a high degree of sensivity and precision of our methodology between pre-ictal and ictal events.

    Neuropeptide Y (NPY) is a well established anticonvulsant and first-in-class antiepileptic neuropeptide. In this study, the controversial role of NPY1 receptors in epilepsy was reassessed by testing two highly selective NPY1 receptor ligands and a mixed NPY1/NPFF receptor antagonist BIBP3226 in a rat model for limbic seizures. While BIBP3226 significantly attenuated the pilocarpine-induced seizures, neither of the highly selective NPY1 receptor ligands altered the seizure severity. Administration of the NPFF1/NPFF2 receptor antagonist RF9 also significantly attenuated limbic seizure activity. To further prove the involvement of NPFF receptors in these seizure-modulating effects, low and high affinity antagonists for the NPFF receptors were tested. We observed that the low affinity ligand failed to exhibit anticonvulsant properties while the two high affinity ligands significantly attenuated the seizures. Continuous NPFF1 receptor agonist administration also inhibited limbic seizures whereas bolus administration of the NPFF1 receptor agonist was without effect. This suggests that continuous agonist perfusion could result in NPFF1 receptor desensitization and mimic NPFF1 receptor antagonist administration. Our data unveil for the first time the involvement of the NPFF system in the management of limbic seizures. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The purpose of this study was to assess school nurses' perceptions of barriers to optimal management of seizures in schools. Eighty-three school nurses completed an electronic survey. Most agreed they felt confident they could identify a seizure (97.6%), give rectal diazepam (83.8%), and handle cluster seizures (67.1%), but fewer were confident they could give intranasal midazolam (63.3%), had specific information about a student's seizures (56.6%), or could swipe a vagus nerve stimulator magnet (47.4%). Nurses were more likely to be available at the time of a seizure in rural (17/20) (85%) versus suburban (21/34) (62%) or urban (8/25) (32%) schools (P = .001). School nurses are comfortable managing seizures in the school setting. However, a specific seizure plan for each child and education on intranasal midazolam and vagus nerve stimulator magnet use are needed. A barrier in urban schools is decreased availability of a nurse to identify seizures and administer treatment. © The Author(s) 2016.

    To examine the effects of age on different aspects of temporal lobe seizure semiology. We performed a video analysis of 605 archived seizures from 155 consecutive patients (age 10 months to 49 years) selected by seizure freedom after temporal lobectomy. Eighty patients had hippocampal sclerosis (HS). Beside semiological seizure classification, we assessed age dependency of several axes of seizure semiology: (1) aura, (2) number of different lateralizing signs, occurrence of ictal (3) emotional signs, (4) autonomic symptoms, (5) automatisms, and (6) secondary generalization as well as (7) the ratio of motor seizure components. From the 155 patients, 117 reported aura, 39 had ictal emotional signs, 51 had autonomic symptoms, 130 presented automatisms, while 18 patients showed secondary generalization at least once during their seizures. Altogether 369 (median: 2/patient) different lateralizing signs were recorded. Frequency of HS (p semiology. Conversely, other aspects (aura, emotional, and autonomic signs) are independent of the maturation process. This is the first report investigating age dependency of epileptic seizure semiology comparing all age groups.

  11. [Brain lateralization and seizure semiology: ictal clinical lateralizing signs]. (United States)

    Horváth, Réka; Kalmár, Zsuzsanna; Fehér, Nóra; Fogarasi, András; Gyimesi, Csilla; Janszky, József


    Clinical lateralizing signs are the phenomena which can unequivocally refer to the hemispheric onset of epileptic seizures. They can improve the localization of epileptogenic zone during presurgical evaluation, moreover, their presence can predict a success of surgical treatment. Primary sensory phenomena such as visual aura in one half of the field of vision or unilateral ictal somatosensory sensation always appear on the contralateral to the focus. Periictal unilateral headache, although it is an infrequent symptom, is usually an ipsilateral sign. Primary motor phenomena like epileptic clonic, tonic movements, the version of head ubiquitously appear contralateral to the epileptogenic zone. Very useful lateralization sign is the ictal hand-dystonia which lateralizes to the contralateral hemisphere in nearly 100%. The last clonus of the secondarily generalized tonic-clonic seizure lateralizes to the ipsilateral hemisphere in 85%. The fast component of ictal nystagmus appears in nearly 100% on the contralateral side of the epileptic focus. Vegetative symptoms during seizures arising from temporal lobe such as spitting, nausea, vomiting, urinary urge are typical for seizures originating from non-dominant (right) hemisphere. Ictal pallor and cold shivers are dominant hemispheric lateralization signs. Postictal unilateral nose wiping refers to the ipsilateral hemispheric focus compared to the wiping hand. Ictal or postictal aphasia refers to seizure arising from dominant hemisphere. Intelligable speech during complex partial seizures appears in non-dominant seizures. Automatism with preserved consciousness refers to the seizures of non-dominant temporal lobe.

  13. Seizure tests distinguish intermittent fasting from the ketogenic diet. (United States)

    Hartman, Adam L; Zheng, Xiangrong; Bergbower, Emily; Kennedy, Michiko; Hardwick, J Marie


    Calorie restriction can be anticonvulsant in animal models. The ketogenic diet was designed to mimic calorie restriction and has been assumed to work by the same mechanisms. We challenged this assumption by profiling the effects of these dietary regimens in mice subjected to a battery of acute seizure tests. Juvenile male NIH Swiss mice received ketogenic diet or a normal diet fed in restricted quantities (continuously or intermittently) for ∼12 days, starting at 3-4 weeks of age. Seizures were induced by the 6 Hz test, kainic acid, maximal electroshock, or pentylenetetrazol. The ketogenic and calorie-restricted diets often had opposite effects depending on the seizure test. The ketogenic diet protected from 6 Hz-induced seizures, whereas calorie restriction (daily and intermittent) increased seizure activity. Conversely, calorie restriction protected juvenile mice against seizures induced by kainic acid, whereas the ketogenic diet failed to protect. Intermittent caloric restriction worsened seizures induced by maximal electroshock but had no effect on those induced by pentylenetetrazol. In contrast to a longstanding hypothesis, calorie restriction and the ketogenic diet differ in their acute seizure test profiles, suggesting that they have different underlying anticonvulsant mechanisms. These findings highlight the importance of the 6 Hz test and its ability to reflect the benefits of ketosis and fat consumption. Wiley Periodicals, Inc. © 2010 International League Against Epilepsy.

  17. Seizure disorders: update of medical and dental considerations. (United States)

    Stoopler, Eric T; Sollecito, Thomas P; Greenberg, Martin S


    Seizure disorders and epilepsy represent neurologic conditions that commonly are seen among patients requiring dental treatment. When dentists possess a working knowledge of seizures, in addition to an understanding of updated therapies for seizure management and oral complications associated with pharmacological therapy, they are able to treat patients with these disorders more effectively. Neurologic consultations and selecting an appropriate venue for treatment may need to be addressed prior to treatment, depending on the level of seizure control. Laboratory tests designed to evaluate medication levels, leukocyte counts, and clotting ability also may be required. Frequent recall visits may be necessary for seizure disorder patients who display adverse oral complications from medication, such as gingival hypertrophy, xerostomia, and oral yeast infections.

  18. Non-Competitive NMDA Receptor Antagonist Hemantane Reduces Ethanol Consumption in Long-Term Alcohol Experienced Rats. (United States)

    Kolik, L G; Nadorova, A V; Seredenin, S B


    Activity of hemantane, an amino adamantane derivative, exhibiting the properties of lowaffinity non-competitive NMDA receptor antagonist, was evaluated in experimental in vivo models of alcoholism. Hemantane had no effects on the formation and manifestation of behavioral sensitization to ethanol in DBA/2 mice. Under conditions of free choice between 10% ethanol and water, hemantane (20 mg/kg/day for 14 days, intraperitoneally) significantly reduced the daily ethanol intake in random-bred male rats with formed alcohol motivation (>4 g/kg of ethanol). During modelling of withdrawal syndrome, hemantane administered intraperitoneally in doses of 5-20 mg/kg dose-dependently attenuated alcohol-deprivation effect after acute withdrawal with no effects on protracted abstinence. It was found that hemantane suppressed alcohol drinking behavior in long-term ethanol experienced rats and attenuated alcohol-seeking behavior after acute withdrawal.

  19. Seizure Induced by Deep Transcranial Magnetic Stimulation in an Adolescent with Depression. (United States)

    Cullen, Kathryn R; Jasberg, Suzanne; Nelson, Brent; Klimes-Dougan, Bonnie; Lim, Kelvin O; Croarkin, Paul E


    Deep transcranial magnetic stimulation (TMS) with an H-1 coil was recently approved by the U.S. Food and Drug Administration (U.S. FDA) for treatment-resistant depression (TRD) in adults. Studies assessing the safety and effectiveness of deep TMS in adolescent TRD are lacking. The purpose of this brief report is to provide a case history of an adolescent enrolled in an investigational deep TMS protocol. A case history is described of the first participant of a sham-controlled clinical trial who had a seizure in the course of deep TMS with parameter settings extrapolated from the adult studies that led to US FDA approval (H-1 coil, 120% target stimulation intensity, 18 Hz, 55 trains of 2-second duration, total 1980 pulses). The participant was a 17-year-old unmedicated female, with no significant medical history and no history of seizures or of drug or alcohol use. Brain magnetic resonance imaging showed no structural abnormalities. She initially received sham, which was well tolerated. During active treatment sessions, titration began at 85% of motor threshold (MT) and increased by 5% per day. Her weekly MT measurements were stable. On her first day of 120% MT (8th active treatment), during the 48th train, the participant had a generalized, tonic-clonic seizure that lasted 90 seconds and resolved spontaneously. She had an emergency medicine evaluation and was discharged home without anticonvulsant medications. There were no further seizures reported at a 6-month follow-up. We report a deep TMS-induced generalized tonic-clonic seizure in an adolescent with TRD participating in a clinical trial. Given the demonstrated benefits of deep TMS for adult TRD, research investigating its use in adolescents with TRD is an important area. However, in light of this experience, additional precautions for adolescents should be considered. We propose that further dose-finding investigations are needed to refine adolescent-specific parameters that may be safe and effective for

  20. A brief history of typical absence seizures - Petit mal revisited. (United States)

    Brigo, Francesco; Trinka, Eugen; Lattanzi, Simona; Bragazzi, Nicola Luigi; Nardone, Raffaele; Martini, Mariano


    In this article, we have traced back the history of typical absence seizures, from their initial clinical description to the more recent nosological position. The first description of absence seizures was made by Poupart in 1705 and Tissot in 1770. In 1824, Calmeil introduced the term "absences", and in 1838, Esquirol for the first time used the term petit mal. Reynolds instead used the term "epilepsia mitior" (milder epilepsy) and provided a comprehensive description of absence seizures (1861). In 1854, Delasiauve ranked absences as the seizure type with lower severity and introduced the concept of idiopathic epilepsy. Otto Binswanger (1899) discussed the role of cortex in the pathophysiology of "abortive seizures", whereas William Gowers (1901) emphasized the importance of a detailed clinical history to identify nonmotor seizures or very mild motor phenomena which otherwise may go unnoticed or considered not epileptic. At the beginning of the 20th Century, the term pyknolepsy was introduced, but initially was not universally considered as a type of epilepsy; it was definitely recognized as an epileptic entity only in 1945, based on electroencephalogram (EEG) recordings. Hans Berger, the inventor of the EEG, made also the first EEG recording of an atypical absence (his results were published only in 1933), whereas the characteristic EEG pattern was reported by neurophysiologists of the Harvard Medical School in 1935. The discovery of EEG made it also possible to differentiate absence seizures from so called "psychomotor" seizures occurring in temporal lobe epilepsy. Penfield and Jasper (1938) considered absences as expression of "centrencephalic epilepsy". Typical absences seizures are now classified by the International League Against Epilepsy among generalized nonmotor (absence) seizures. Copyright © 2018 Elsevier Inc. All rights reserved.

  1. Depiction of seizure first aid management in medical television dramas. (United States)

    Moeller, Andrew D; Moeller, Jeremy J; Rahey, Susan R; Sadler, R Mark


    The objective of this study was to investigate whether medical television dramas portray proper seizure first aid. Episodes of the four highest-rated US medical dramas ("Grey's Anatomy," "House M.D.", "Private Practice," and "ER") were screened for the presence of seizures. "Patient" age, sex, semiology, and etiology were recorded. The appropriateness of seizure first aid management was determined by comparison to the Epilepsy Foundation of America (EFA) guidelines. Among 364 television programs, 65 seizures (in 59 individuals) were identified (30 males; 29 females). Seizures were primary or secondarily generalized tonic-clonic in 53 (81.5%) cases. Other seizure types included complex partial (5, 7.7%), simple partial (1, 1.5%), myoclonic (1, 1.5%), absence (1, 1.5%), and psychogenic (1, 1.5%). On 63 occasions (96.9%), first aid was performed by a health care professional. First aid management was judged appropriate in 21 (32.3%) seizures, inappropriate in 28 (43.1%), and indeterminate in 16 (24.6%). Inappropriate practices included holding the person down (17, 26.2%), trying to stop the involuntary movements (10, 15.4%) and putting something in the person's mouth (11, 16.9%). The first aid management of seizures performed by actors portraying health care professionals was inappropriate in nearly half of all cases. Inaccurate depiction of seizure first aid management may contribute to misinformation of the general public. The television industry could easily incorporate the simple first aid EFA seizure guidelines as a public service without sacrificing dramatic impact.

  4. Intramuscular and rectal therapies of acute seizures. (United States)

    Leppik, Ilo E; Patel, Sima I


    The intramuscular (IM) and rectal routes are alternative routes of delivery for antiepileptic drugs (AEDs) when the intravenous route is not practical or possible. For treatment of acute seizures, the AED used should have a short time to maximum concentration (Tmax). Some AEDs have preparations that may be given intramuscularly. These include the benzodiazepines (diazepam, lorazepam, and midazolam) and others (fosphenytoin, levetiracetam). Although phenytoin and valproate have parenteral preparations, these should not be given intramuscularly. A recent study of prehospital treatment of status epilepticus evaluated a midazolam (MDZ) autoinjector delivering IM drug compared to IV lorazepam (LZP). Seizures were absent on arrival to the emergency department in 73.4% of the IM MDZ compared to a 63.4% response in LZP-treated subjects (p administration as solutions, gels, and suppositories. In a placebo-controlled study, diazepam (DZP) was administered at home by caregivers in doses that ranged from 0.2 to 0.5 mg/kg. Diazepam was superior to placebo in reduced seizure frequency in children (p intramuscularly and DZP given rectally appear to have the properties required for rapid enough absorption to be useful when intravenous routes are not possible. Some drugs cannot be administered rectally owing to factors such as poor absorption or poor solubility in aqueous solutions. The relative rectal bioavailability of gabapentin, oxcarbazepine, and phenytoin is so low that the current formulations are not considered to be suitable for administration by this route. When administered as a solution, diazepam is rapidly absorbed rectally, reaching the Tmax within 5-20 min in children. By contrast, rectal administration of lorazepam is relatively slow, with a Tmax of 1-2h. The dependence of gabapentin on an active transport system, and the much-reduced surface area of the rectum compared with the small intestine, may be responsible for its lack of absorption from the rectum. This

  5. Delayed myelination and neurodevelopment in male seizure-prone versus seizure-resistant rats. (United States)

    Sharma, Pragati; Powell, Kim L; Wlodek, Mary E; O'Brien, Terence J; Gilby, Krista L


    Aberrant myelination and developmental delay have been reported in epilepsy. However, it is unclear whether these are linked to intrinsic mechanisms that support a predisposition toward seizures and the development of epilepsy. Thus, we compared rates of myelination and neurodevelopment in male rats selectively bred for enhanced susceptibility to kindling epileptogenesis (FAST) with male rats bred for resistance (SLOW). Myelin-specific gene expression was compared in the brainstem, cerebellum, and cerebral hemisphere of FAST and SLOW rats on postnatal days (PNDs) 5, 11, 17, 23, and 90 to determine strain-specific myelination rates. Myelin protein levels were also compared at PNDs 5 and 23 in the brainstem. Relative rates of neurodevelopment were evaluated between PNDs 5 and 21 using physical growth landmarks and neuromotor tests including righting reflex, cliff avoidance, negative geotaxis, and locomotor activity. Myelin-specific mRNA expression was significantly down-regulated in FAST rats on PNDs 5 and 11 in all 3 brain structures, indicating relatively delayed myelination. Likewise, corresponding protein levels were significantly lower in FAST brainstem on PND 5. Developmental delay was evident in the FAST strain such that only 9% of FAST pups, compared to 81% of SLOW, had open eyes by PND 13, locomotor activity was significantly reduced between PNDs 12 and 16, and neuromotor task acquisition was delayed between PNDs 5 and 10. Relative delays in myelination and neurodevelopment co-occurred in the seizure-prone FAST strain in the absence of seizures. These findings suggest these symptoms are not seizure-induced and may be mechanistically linked to an underlying pathophysiology supporting a predisposition toward developing epilepsy.

  6. Resected Brain Tissue, Seizure Onset Zone and Quantitative EEG Measures: Towards Prediction of Post-Surgical Seizure Control. (United States)

    Rummel, Christian; Abela, Eugenio; Andrzejak, Ralph G; Hauf, Martinus; Pollo, Claudio; Müller, Markus; Weisstanner, Christian; Wiest, Roland; Schindler, Kaspar


    Epilepsy surgery is a potentially curative treatment option for pharmacoresistent patients. If non-invasive methods alone do not allow to delineate the epileptogenic brain areas the surgical candidates undergo long-term monitoring with intracranial EEG. Visual EEG analysis is then used to identify the seizure onset zone for targeted resection as a standard procedure. Despite of its great potential to assess the epileptogenicty of brain tissue, quantitative EEG analysis has not yet found its way into routine clinical practice. To demonstrate that quantitative EEG may yield clinically highly relevant information we retrospectively investigated how post-operative seizure control is associated with four selected EEG measures evaluated in the resected brain tissue and the seizure onset zone. Importantly, the exact spatial location of the intracranial electrodes was determined by coregistration of pre-operative MRI and post-implantation CT and coregistration with post-resection MRI was used to delineate the extent of tissue resection. Using data-driven thresholding, quantitative EEG results were separated into normally contributing and salient channels. In patients with favorable post-surgical seizure control a significantly larger fraction of salient channels in three of the four quantitative EEG measures was resected than in patients with unfavorable outcome in terms of seizure control (median over the whole peri-ictal recordings). The same statistics revealed no association with post-operative seizure control when EEG channels contributing to the seizure onset zone were studied. We conclude that quantitative EEG measures provide clinically relevant and objective markers of target tissue, which may be used to optimize epilepsy surgery. The finding that differentiation between favorable and unfavorable outcome was better for the fraction of salient values in the resected brain tissue than in the seizure onset zone is consistent with growing evidence that spatially

    Joanna M. Janczak


    Full Text Available Body packing is a common method for illegal drug trafficking. Complications associated with body packing can be severe and even lead to rapid death. Thus, a timely diagnosis is warranted. As most body packers initially do not show any symptoms, making a correct diagnosis can be rather challenging. We describe a case of a 41-year-old male, who was admitted with an epileptic seizure and who turned out to be a cocaine intoxicated body packer. Due to neurological and cardiovascular deterioration an emergency surgery was performed. Four bags of cocaine could be removed. We discuss the current management regimen in symptomatic and asymptomatic body packers and highlight pearls and pitfalls with diagnosis and treatment.

  8. Epileptic Seizure, Postictal Hemiparesis, and Hyperleukocytosis (United States)

    Olivieri, Martin; Kurnik, Karin; Heinen, Florian; Schmid, Irene; Hoffmann, Florian; Reiter, Karl; Gerstl, Lucia


    Introduction: Acute ischemic stroke (AIS) is a rare event in infancy. Besides vasculopathy, thrombophilia, or cardiac disorders, cancer and chemotherapy are known predisposing factors for AIS. Leukemia can be associated with different abnormal coagulation parameters, but severe bleeding or thrombosis occurs rarely. Clinical Course: We report the case of a 2-year-old boy who was presented to our emergency ward after a prolonged seizure with right sided postictal hemiparesis. Cranial computed tomography scan revealed a large infarction and edema due to thrombosis of the left carotid artery, the middle cerebral artery, and the anterior cerebral artery. Laboratory workup showed 196 g/L leukocytes with 75% myeloid blast cells. Immediate exchange transfusion, hydration, and chemotherapy with cytarabine were started. During the hospital course intracranial pressure increased and the patient developed a unilateral dilated pupil unresponsive to light. Cranial computed tomography scan revealed a new infarction in the right middle cerebral artery territory. Refractory increased intracranial pressure and brain stem herniation developed, and the child died 3 days after admission to hospital. Conclusion: Seizures with postictal hemiparesis due to cerebral infarction can be a rare manifestation of acute myeloid leukemia. Leukocytosis and cancer-induced coagulopathy are main reasons for thrombosis and/or hemorrhage. High leukocyte counts need immediate interventions with hydration, careful chemotherapy, and perhaps exchange transfusion or leukapharesis. In the presence of thrombosis, anticoagulation must be discussed despite the risk of bleeding due to hyperfibrinolysis and low platelet counts. Mortality may be reduced by awareness of this rare presentation of leukemia and prompt institution of leucoreductive treatment. PMID:28229095

  10. Alcoholism & depression. (United States)

    Hall, Mellisa


    One out of 2 Americans report drinking on a routine basis, making the excessive consumption of alcohol the third leading cause of preventable death in America (). Alcoholism and depression are common comorbidities that home healthcare professionals frequently encounter. To achieve the best patient outcomes, alcoholism should be addressed initially. Although all age groups are at risk, alcoholism and depression occur in more than 8 percent of older adults. Prevention through identifying alcohol use early in adolescence is vital to reduce the likelihood of alcohol dependence. This article provides an overview of the long-term effects of alcohol abuse, including alcoholic cirrhosis and hepatic encephalopathy. The diagnostic criteria for substance dependence and ideas for nonthreatening screening questions to use with patients who are adolescent or older are discussed. While providing patient care, home healthcare nurses share the patient's intimate home environment. This environment is perceived as a safe haven by the patient and home care nurses can take advantage of counseling and treatment opportunities in this nonthreatening environment.

  11. Histamine H1 antagonists and clinical characteristics of febrile seizures. (United States)

    Zolaly, Mohammed A


    The purpose of this study was to determine whether seizure susceptibility due to antihistamines is provoked in patients with febrile seizures. The current descriptive study was carried out from April 2009 to February 2011 in 250 infants and children who visited the Madinah Maternity and Children's Hospital as a result of febrile convulsions. They were divided into two groups according to administration of antihistamines at the onset of fever. Detailed clinical manifestations were compared between patients with and without administration of antihistamines. The time from fever detection to seizure onset was significantly shorter in the antihistamine group than that in the nonantihistamine group, and the duration of seizures was significantly longer in the antihistamine group than in the nonantihistamine group. No significant difference was found in time from fever detection to seizure onset or seizure duration between patients who received a first-generation antihistamine and those who received a second-generation antihistamine. Due to their central nervous system effects, H1 antagonists should not be administered to patients with febrile seizures and epilepsy. Caution should be exercised regarding the use of histamine H1 antagonists in young infants, because these drugs could potentially disturb the anticonvulsive central histaminergic system.

  12. A case of seizures induced by abstract reasoning. (United States)

    Tatsuzawa, Yasutaka; Yoshino, Aihide; Nomura, Soichiro


    We describe a case of reflex seizures induced by abstract reasoning but not other cognitive processes. The patient, a 46-year-old man, experienced myoclonic seizures whenever he played shogi (Japanese chess). To identify the critical thought processes responsible for inducing his seizures, we monitored his clinical seizures and epileptiform discharges while he performed comprehensive neuropsychological tests, including the Wechsler Adult Intelligence Scale-Revised (WAIS-R), spatial working memory, mental rotation, and Wisconsin Card Sorting Test (WCST) tasks. A myoclonic seizure occurred only during the WCST. Generalized 3- to 5-Hz spike-and-slow-wave bursts occurred repeatedly during the Block Design subtest of the WAIS-R and the WCST, whereas no discharges occurred during other subtests of the WAIS-R including the calculation, spatial working memory, and mental rotation tasks. These results indicate that abstract reasoning, independent of other cognitive processes, could induce the patient's epileptiform discharges, suggesting that his reflex seizures might be a distinct subtype of nonverbal thinking-induced seizures.

  13. Electrographic Changes Accompanying Recurrent Seizures under Ketogenic Diet Treatment

    Directory of Open Access Journals (Sweden)

    Chiara Lucchi


    Full Text Available The ketogenic diet (KD is increasingly used to treat epilepsy refractory to antiepileptic drugs and other neurological disorders. In animal models, the KD was found to increase the threshold to seizures induced by different convulsive stimulations. However, in models in which suprathreshold stimuli were used, a paradoxical seizure worsening was consistently observed in KD-fed animals. To better define this phenomenon, we characterized the electrographic response to seizures induced in mice which were treated with the KD, and then corneally stimulated at 6-Hz in four different sessions. We also evaluated the electroencephalogram (EEG in three patients in which the KD was associated with a paradoxical worsening of epileptic seizures. Although seizures were initially less severe, a remarkable prolongation of the electrographic response was observed in mice receiving the KD from the second session of 6-Hz corneal stimulation and onwards. The EEG was also markedly altered in the presence of progressive seizure aggravation observed in children treated with the KD, specifically one affected by Lennox–Gastaut syndrome and two by type I lissencephaly. These results suggest that when seizures are induced or recur because of resistance to therapeutic interventions, the KD may change the EEG by potentiating the electrographic epileptic activity.

  14. Preventing and treating posttraumatic seizures: the human experience. (United States)

    Temkin, Nancy R


    Posttraumatic epilepsy presents an ideal target for prevention efforts. Traumatic brain injury (TBI) is common, characteristics that put people at high risk such as penetrating injury or subdural hematoma or provoked seizures are easily identified, and the latency between the injury and the onset of epileptic seizures is frequently short. Several drugs have been tested for their ability to prevent provoked seizures and epilepsy after TBI. We describe the design of those studies and their results. Phenytoin and carbamazepine significantly reduce the incidence of provoked seizures. Phenobarbital and the combination of phenobarbital and phenytoin also look promising for reducing provoked seizures, but small sample sizes in the studies evaluating these drugs do not allow definitive conclusions. None of the drugs studied (phenytoin, phenobarbital, their combination, carbamazepine, valproate, or magnesium) have shown reliable evidence that they prevent, or even suppress, epileptic seizures after TBI. For most of the regimens tested (the phenytoin/phenobarbital combination being the exception), the best estimate of effect is under a 25% reduction in posttraumatic seizures, well less than the 50% reduction most studies were designed to detect. The evaluation of the tested drugs has serious limitations, however, and antiepileptic drugs (AEDs) developed since 1980 and other compounds have barely been tested at all. Better understanding the process of epileptogenesis, testing treatments that demonstrate antiepileptogenic effects in the laboratory, and performing thorough preclinical and phase II evaluations before attempting definitive trials should greatly improve the chance of identifying ways to prevent posttraumatic epilepsy, providing the ultimate cure for this condition.

  15. Cocaine-Associated Seizures and Incidence of Status Epilepticus

    Directory of Open Access Journals (Sweden)

    Majlesi, Nima DO


    Full Text Available Objectives: Acute complications from cocaine abuse are commonly treated in the emergency department (ED; one of the most consequential is status epilepticus. The incidence of this complication is not clearly defined in the prior literature on cocaine-associated sequelae. We evaluated the incidence of status epilepticus in patients with seizures secondary to suspected cocaine use.Methods: We performed a retrospective multi-center study of patients with seizures resulting from cocaine use. We identified study subjects at 15 hospitals by record review and conducted a computer-assisted records search to identify patients with seizures for each institution over a four-year period. We selected subjects from this group on the basis of cocaine use and determined the occurrence of status epilepticus among them. Data were collected on each subject using a standardized data collection form.Results: We evaluated 43 patients in the ED for cocaine-associated seizures. Their age range was 17 to 54, with a mean age was 31 years; 53% were male. Of 43 patients, 42 experienced a single tonic-clonic seizure and one developed status epilepticus. All patients had either a history of cocaine use or positive urine drug screen for cocaine.Conclusion: Despite reported cases of status epilepticus with cocaine-induced seizures, the incidence of this complication was unclear based on prior literature. This study shows that most cocaine-associated seizures are self-limited. [West J Emerg Med. 2010; 11(2:157-160.

  16. Clinical characteristics of patients seizure following the 2016 Kumamoto earthquake. (United States)

    Inatomi, Yuichiro; Nakajima, Makoto; Yonehara, Toshiro; Ando, Yukio


    To investigate the clinical characteristics of patients with seizure following the 2016 Kumamoto earthquake. We retrospectively studied patients with seizure admitted to our hospital for 12weeks following the earthquake. We compared the clinical backgrounds and characteristics of the patients: before (the same period from the previous 3years) and after the earthquake; and the early (first 2weeks) and late (subsequent 10weeks) phases. A total of 60 patients with seizure were admitted to the emergency room after the earthquake, and 175 (58.3/year) patients were admitted before the earthquake. Of them, 35 patients with seizure were hospitalized in the Department of Neurology after the earthquake, and 96 (32/year) patients were hospitalized before the earthquake. In patients after the earthquake, males and non-cerebrovascular diseases as an epileptogenic disease were seen more frequently than before the earthquake. During the early phase after the earthquake, female, first-attack, and non-focal-type patients were seen more frequently than during the late phase after the earthquake. These characteristics of patients with seizure during the early phase after the earthquake suggest that many patients had non-epileptic seizures. To prevent seizures following earthquakes, mental stress and physical status of evacuees must be assessed. Copyright © 2017. Published by Elsevier Ltd.

    was increased by 75%; in the case of pre-immobilization duration of seizures increased by 206% and the zinc content - 50%; in the case of pre-alcoholization duration of seizures increased by 234%, and a chelating zinc content - 75%. These results suggest a chelating zinc epileptiform participate in the mechanisms of seizures and, possibly, the development of mechanisms of temporal lobe epilepsy (hippocampal. The results of studies of zinc changes in central and peripheral organs of zinc-containing simulated at different functional states allow us to make the assumption that there is a common mechanism for coordination of functional activity as the hippocampus and other zinc-containing bodies with the help of changes in the chelating zinc metabolism, regulation is carried out by means of the hippocampus.

  18. Definition and classification of epilepsy. Classification of epileptic seizures 2016

    Directory of Open Access Journals (Sweden)

    K. Yu. Mukhin


    Full Text Available Epilepsy is one of the most common neurological diseases, especially in childhood and adolescence. The incidence varies from 15 to 113 cases per 100 000 population with the maximum among children under 1 year old. The prevalence of epilepsy is high, ranging from 5 to 8 cases (in some regions – 10 cases per 1000 children under 15 years old. Classification of the disease has great importance for diagnosis, treatment and prognosis. The article presents a novel strategy for classification of epileptic seizures, developed in 2016. It contains a number of brand new concepts, including a very important one, saying that some seizures, previously considered as generalized or focal only, can be, in fact, both focal and generalized. They include tonic, atonic, myoclonic seizures and epileptic spasms. The term “secondarily generalized seizure” is replace by the term “bilateral tonic-clonic seizure” (as soon as it is not a separate type of epileptic seizures, and the term reflects the spread of discharge from any area of cerebral cortex and evolution of any types of focal seizures. International League Against Epilepsy recommends to abandon the term “pseudo-epileptic seizures” and replace it by the term “psychogenic non-epileptic seizures”. If a doctor is not sure that seizures have epileptic nature, the term “paroxysmal event” should be used without specifying the disease. The conception of childhood epileptic encephalopathies, developed within this novel classification project, is one of the most significant achievements, since in this case not only the seizures, but even epileptiform activity can induce severe disorders of higher mental functions. In addition to detailed description of the new strategy for classification of epileptic seizures, the article contains a comprehensive review of the existing principles of epilepsy and epileptic seizures classification.

  19. A computational study of stimulus driven epileptic seizure abatement.

    Directory of Open Access Journals (Sweden)

    Peter Neal Taylor

    Full Text Available Active brain stimulation to abate epileptic seizures has shown mixed success. In spike-wave (SW seizures, where the seizure and background state were proposed to coexist, single-pulse stimulations have been suggested to be able to terminate the seizure prematurely. However, several factors can impact success in such a bistable setting. The factors contributing to this have not been fully investigated on a theoretical and mechanistic basis. Our aim is to elucidate mechanisms that influence the success of single-pulse stimulation in noise-induced SW seizures. In this work, we study a neural population model of SW seizures that allows the reconstruction of the basin of attraction of the background activity as a four dimensional geometric object. For the deterministic (noise-free case, we show how the success of response to stimuli depends on the amplitude and phase of the SW cycle, in addition to the direction of the stimulus in state space. In the case of spontaneous noise-induced seizures, the basin becomes probabilistic introducing some degree of uncertainty to the stimulation outcome while maintaining qualitative features of the noise-free case. Additionally, due to the different time scales involved in SW generation, there is substantial variation between SW cycles, implying that there may not be a fixed set of optimal stimulation parameters for SW seizures. In contrast, the model suggests an adaptive approach to find optimal stimulation parameters patient-specifically, based on real-time estimation of the position in state space. We discuss how the modelling work can be exploited to rationally design a successful stimulation protocol for the abatement of SW seizures using real-time SW detection.

  20. Seizure semiology and EEG findings in mitochondrial diseases. (United States)

    Chevallier, Justyna A; Von Allmen, Gretchen K; Koenig, Mary Kay


    Seizures constitute a frequent yet under-described manifestation of mitochondrial disorders (MDs). The aim of this study was to describe electroencephalography (EEG) findings and clinical seizure types in a population of children and adults with mitochondrial disease. Retrospective chart review of 165 records of children and adults with mitochondrial disease seen in the University of Texas Houston Mitochondrial Center between 2007 and 2012 was performed; all subjects were diagnosed with confirmed mitochondrial disease. EEG findings and clinical data, including seizure semiology and response to antiepileptic drugs (AEDs), were analyzed and categorized. Sixty-six percent (109/165) of subjects had a routine EEG performed. Sixty-one percent (67/109) of EEG studies were abnormal and 85% (56/67) had epileptiform discharges. The most common EEG finding was generalized slowing (40/67, 60%). The most frequent category of epileptiform activity seen was multifocal discharges (41%), followed by focal (39%) and generalized (39%) discharges. Clinical seizures were seen in 55% of subjects and the most common types of seizures observed were complex partial (37%) and generalized tonic-clonic (GTC; 37%). The most common seizure type in patients with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) was GTC (33%), with generalized or focal discharges seen on EEG. In Leigh syndrome GTC (11%) and complex partial (11%) seizures were the most frequent types. Of 60 subjects with clinical seizures, 28% were intractable to medical treatment. Mitochondrial disorder should be included in the list of differential diagnosis in any child that presents with encephalopathy, seizures, and a fluctuating clinical course. Given the relatively high prevalence of EEG abnormalities in patients with MD, EEG should be performed during initial evaluation in all patients with MD, not only upon clinical suspicion of epilepsy.

  1. Smoking prevalence and seizure control in Chinese males with epilepsy. (United States)

    Gao, Hui; Sander, Josemir W; Du, Xudong; Chen, Jiani; Zhu, Cairong; Zhou, Dong


    Smoking has a negative effect on most diseases, yet it is under-investigated in people with epilepsy; thus its role is not clear in the general population with epilepsy. We performed a retrospective pilot study on males with epilepsy to determine the smoking rate and its relationship with seizure control using univariate analysis to calculate odds ratios (ORs) and also used a multi-variate logistic regression model. The smoking rate in our sample of 278 individuals was 25.5%, which is lower than the general Chinese population smoking rate among males of 52.1%. We used two classifications: the first classified epilepsy as generalized, or by presumed topographic origin (temporal, frontal, parietal and occipital). The second classified the dominant seizure type of an individual as generalized tonic clonic seizure (GTCS), myoclonic seizure (MS), complex partial seizure (CPS), simple partial seizure (SPS), and secondary GTCS (sGTCS). The univariable analysis of satisfactory seizure control profile and smoking rate in both classifications showed a trend towards a beneficial effect of smoking although most were not statistically significant. Considering medication is an important confounding factor that would largely influence seizure control, we also conducted multi-variable analysis for both classifications with drug numbers and dosage. The result of our model also suggested that smoking is a protective factor. Our findings seem to suggest that smoking could have a potential role in seizure control although confounders need exploration particularly in view of the potential long term health effects. Replication in a much larger sample is needed as well as case control studies to elucidate this issue. Copyright © 2017 Elsevier Inc. All rights reserved.

  2. Influence of stress associated with chronic alcohol exposure on drinking. (United States)

    Becker, Howard C


    Stress is commonly regarded as an important trigger for relapse and a significant factor that promotes increased motivation to drink in some individuals. However, the relationship between stress and alcohol is complex, likely changing in form during the transition from early moderated alcohol use to more heavy uncontrolled alcohol intake. A growing body of evidence indicates that prolonged excessive alcohol consumption serves as a potent stressor, producing persistent dysregulation of brain reward and stress systems beyond normal homeostatic limits. This progressive dysfunctional (allostatic) state is characterized by changes in neuroendocrine and brain stress pathways that underlie expression of withdrawal symptoms that reflect a negative affective state (dysphoria, anxiety), as well as increased motivation to self-administer alcohol. This review highlights literature supportive of this theoretical framework for alcohol addiction. In particular, evidence for stress-related neural, physiological, and behavioral changes associated with chronic alcohol exposure and withdrawal experience is presented. Additionally, this review focuses on the effects of chronic alcohol-induced changes in several pro-stress neuropeptides (corticotropin-releasing factor, dynorphin) and anti-stress neuropeptide systems (nocicepton, neuropeptide Y, oxytocin) in contributing to the stress, negative emotional, and motivational consequences of chronic alcohol exposure. Studies involving use of animal models have significantly increased our understanding of the dynamic stress-related physiological mechanisms and psychological underpinnings of alcohol addiction. This, in turn, is crucial for developing new and more effective therapeutics for treating excessive, harmful drinking, particularly stress-enhanced alcohol consumption.

  3. Reversible loss of reproductive fitness in zebrafish on chronic alcohol exposure. (United States)

    Dewari, Pooran Singh; Ajani, Funmilola; Kushawah, Gopal; Kumar, Damera Santhosh; Mishra, Rakesh K


    Alcoholism is one of the most prevalent diseases in society and causes significant health and social problems. Alcohol consumption by pregnant women is reported to cause adverse effects on the physical and psychological growth of the fetus. However, the direct effect of chronic alcohol consumption on reproductive fitness has not been tested. In recent years, the zebrafish (Danio rerio) has emerged as a versatile model system to study the effects of alcohol on behavior and embryonic development. We utilized the zebrafish model system to address the effect of chronic alcohol exposure (0.5% alcohol in the holding tank for 9 weeks) on reproductive capacity. We found a dramatic decrease in fecundity, measured by counting the number of eggs laid, when at least one of the parents is subject to chronic alcohol exposure. Interestingly, a 9-week alcohol withdrawal program completely restored the reproductive capacity of the treated subjects. In agreement with observations on fecundity, the chronic alcohol exposure leads to increased anxiety, as measured by the novel-tank diving assay. Conversely, the withdrawal program diminished heightened anxiety in alcohol-exposed subjects. Our results highlight the adverse effects of chronic alcohol exposure on the reproductive capacity of both males and females, and underscore the utility of the zebrafish model system to understand the biology of chronic alcoholism.

  4. Budget impact analysis of adjunctive therapy with lacosamide for partial-onset epileptic seizures in Belgium. (United States)

    Simoens, Steven


    This study aims to compute the budget impact of lacosamide, a new adjunctive therapy for partial-onset seizures in epilepsy patients from 16 years of age who are uncontrolled and having previously used at least three anti-epileptic drugs from a Belgian healthcare payer perspective. The budget impact analysis compared the 'world with lacosamide' to the 'world without lacosamide' and calculated how a change in the mix of anti-epileptic drugs used to treat uncontrolled epilepsy would impact drug spending from 2008 to 2013. Data on the number of patients and on the market shares of anti-epileptic drugs were taken from Belgian sources and from the literature. Unit costs of anti-epileptic drugs originated from Belgian sources. The budget impact was calculated from two scenarios about the market uptake of lacosamide. The Belgian target population is expected to increase from 5333 patients in 2008 to 5522 patients in 2013. Assuming that the market share of lacosamide increases linearly over time and is taken evenly from all other anti-epileptic drugs (AEDs), the budget impact of adopting adjunctive therapy with lacosamide increases from €5249 (0.1% of reference drug budget) in 2008 to €242,700 (4.7% of reference drug budget) in 2013. Assuming that 10% of patients use standard AED therapy plus lacosamide, the budget impact of adopting adjunctive therapy with lacosamide is around €800,000-900,000 per year (or 16.7% of the reference drug budget). Adjunctive therapy with lacosamide would raise drug spending for this patient population by as much as 16.7% per year. However, this budget impact analysis did not consider the fact that lacosamide reduces costs of seizure management and withdrawal. The literature suggests that, if savings in other healthcare costs are taken into account, adjunctive therapy with lacosamide may be cost saving.

    Andrabi, Sara; Greene, Spencer; Moukaddam, Nidal; Moukkadam, Nidal; Li, Benjamin


    New drugs of abuse continue to emerge, including synthetic cannabinoids, synthetic cathinones, and hallucinogens. It is important to recognize their individual psychopharmacologic properties, symptoms of intoxication, and symptoms of withdrawal. Providers must be vigilant of acute medical or psychiatric complications that may arise from use of these substances. Treatment of the patient also includes recognition of any substance use disorders as well as comorbid psychiatric disorders. Although pharmacologic treatments for substance use disorder (of the drugs included in this article) are limited, there are a variety of psychotherapeutic modalities that may be of some benefit.

  10. Neural mechanisms underlying morphine withdrawal in addicted patients: a review

    Directory of Open Access Journals (Sweden)

    Nima Babhadiashar


    Full Text Available Morphine is one of the most potent alkaloid in opium, which has substantial medical uses and needs and it is the first active principle purified from herbal source. Morphine has commonly been used for relief of moderate to severe pain as it acts directly on the central nervous system; nonetheless, its chronic abuse increases tolerance and physical dependence, which is commonly known as opiate addiction. Morphine withdrawal syndrome is physiological and behavioral symptoms that stem from prolonged exposure to morphine. A majority of brain regions are hypofunctional over prolonged abstinence and acute morphine withdrawal. Furthermore, several neural mechanisms are likely to contribute to morphine withdrawal. The present review summarizes the literature pertaining to neural mechanisms underlying morphine withdrawal. Despite the fact that morphine withdrawal is a complex process, it is suggested that neural mechanisms play key roles in morphine withdrawal.

  11. Why withdrawal from the European Union is undemocratic

    Olsen, Tore Vincents; Rostbøll, Christian F.


    The Lisbon Treaty from 2009 introduced the possibility for individual member states to withdraw from the European Union (EU) on the basis of a unilateral decision. In June 2016 the UK decided to leave the EU invoking article 50 of the treaty. But is withdrawal democratically legitimate? In fact...... argue that it is the effect of withdrawal on the status of citizens as free and equal that is decisive and that explains why unilateral withdrawal of subunits from larger units is democratically illegitimate. Moreover, on the ‘all affected status principle’ that we develop, even multilaterally agreed...... withdrawal is undemocratic because the latter diminishes the future ability of citizens to make decisions together regarding issues that affect their status as free and equal. On this basis, we conclude that it is undemocratic for a member state such as the UK to withdraw from the European Union....

  12. Epigenetics—Beyond the Genome in Alcoholism (United States)

    Starkman, Bela G.; Sakharkar, Amul J.; Pandey, Subhash C.


    Genetic and environmental factors play a role in the development of alcoholism. Whole-genome expression profiling has highlighted the importance of several genes that may contribute to alcohol abuse disorders. In addition, more recent findings have added yet another layer of complexity to the overall molecular mechanisms involved in a predisposition to alcoholism and addiction by demonstrating that processes related to genetic factors that do not manifest as DNA sequence changes (i.e., epigenetic processes) play a role. Both acute and chronic ethanol exposure can alter gene expression levels in specific neuronal circuits that govern the behavioral consequences related to tolerance and dependence. The unremitting cycle of alcohol consumption often includes satiation and self-medication with alcohol, followed by excruciating withdrawal symptoms and the resultant relapse, which reflects both the positive and negative affective states of alcohol addiction. Recent studies have indicated that behavioral changes induced by acute and chronic ethanol exposure may involve chromatin remodeling resulting from covalent histone modifications and DNA methylation in the neuronal circuits involving a brain region called the amygdala. These findings have helped identify enzymes involved in epigenetic mechanisms, such as the histone deacetylase, histone acetyltransferase, and DNA methyltransferase enzymes, as novel therapeutic targets for the development of future pharmacotherapies for the treatment of alcoholism.

    The effect of pretreatment with essential oils (EOs) from eight aromatic plants on the seizure latency and severity of pentylenetetrazol- (PTZ-) induced seizures in mice was evaluated. Weight-dependent doses of Rosmarinus officinalis, Ocimum basilicum, Mentha spicata, Mentha pulegium, Lavandula angustifolia, Mentha piperita, Origanum dictamnus, and Origanum vulgare, isolated from the respective aromatic plants from NE Greece, were administered 60 minutes prior to intraperitoneal (i.p.) injection of a lethal dose of PTZ to eight respective groups of Balb-c mice. Control group received only one i.p. PTZ injection. Motor and behavioral activity of the animals after EOs administration, development of tonic-clonic seizures, seizure latency and severity, and percentage of survival after PTZ administration were determined for each group. All groups of mice treated with the EOs showed reduced activity and stability after the administration of the oil, except for those treated with O. vulgare (100% mortality after the administration of the oil). After PTZ administration, mice from the different groups showed increased latency and reduced severity of seizures (ranging from simple twitches to complete seizures). Mice who had received M. piperita demonstrated no seizures and 100% survival. The different drastic component and its concentration could account for the diversity of anticonvulsant effects.

    Full Text Available To evaluate the seizure characteristics and outcome after immunotherapy in adult patients with autoimmune encephalitis (AE and new-onset seizure.Adult (age ≥18 years patients with AE and new-onset seizure who underwent immunotherapy and were followed-up for at least 6 months were included. Seizure frequency was evaluated at 2-4 weeks and 6 months after the onset of the initial immunotherapy and was categorized as "seizure remission", "> 50% seizure reduction", or "no change" based on the degree of its decrease.Forty-one AE patients who presented with new-onset seizure were analysed. At 2-4 weeks after the initial immunotherapy, 51.2% of the patients were seizure free, and 24.4% had significant seizure reduction. At 6 months, seizure remission was observed in 73.2% of the patients, although four patients died during hospitalization. Rituximab was used as a second-line immunotherapy in 12 patients who continued to have seizures despite the initial immunotherapy, and additional seizure remission was achieved in 66.6% of them. In particular, those who exhibited partial response to the initial immunotherapy had a better seizure outcome after rituximab, with low adverse events.AE frequently presented as seizure, but only 18.9% of the living patients suffered from seizure at 6 months after immunotherapy. Aggressive immunotherapy can improve seizure outcome in patients with AE.
