    The legitimacy of nonsubstance addictions has received increased attention from clinicians, researchers and the general population as more and more individuals report symptoms consistent with impairment of impulse control. The clinical presentation of these disorders is varied, as compulsive activities may include: gambling, eating, sex, shopping, use of the Internet or videogames or even exercising, working or falling in love. As such, there is great controversy in diagnosing, treating or even naming these conditions, as many of these behaviors are daily rituals instrumental to our ultimate survival. Historically, the phrase "impulse control disorders" described these conditions but many researchers and clinicians also use the term "behavioral addictions," "process addictions" or "impulsive-compulsive behaviors" to report behavioral pathology. This review summarizes the data of each of these behavioral addictions from epidemiology to neurobiology to treatment options. Research suggests similarities between natural and drug reward processing but clinical evidence supports the utilization of treatment modalities for these behavioral conditions that can sometimes differ from traditional drug treatment.

    It is increasingly recognized that studying drug taking in laboratory animals does not equate to studying genuine addiction, characterized by loss of control over drug use. This has inspired recent work aimed at capturing genuine addiction-like behavior in animals. In this work, we summarize empirical evidence for the occurrence of several DSM-IV-like symptoms of addiction in animals after extended drug use. These symptoms include escalation of drug use, neurocognitive deficits, resistance to...

    It is increasingly recognized that studying drug taking in laboratory animals does not equate to studying genuine addiction, characterized by loss of control over drug use. This has inspired recent work aimed at capturing genuine addiction-like behavior in animals. In this work, we summarize empirical evidence for the occurrence of several DSM-IV-like symptoms of addiction in animals after extended drug use. These symptoms include escalation of drug use, neurocognitive deficits, resistance to extinction, increased motivation for drugs, preference for drugs over nondrug rewards, and resistance to punishment. The fact that addiction-like behavior can occur and be studied in animals gives us the exciting opportunity to investigate the neural and genetic background of drug addiction, which we hope will ultimately lead to the development of more effective treatments for this devastating disorder.

    The Internet is increasingly influential in the lives of adolescents. Although there are many positives, there are also risks related to excessive use and addiction. It is important to recognize clinical signs and symptoms of Internet addiction (compulsive use, withdrawal, tolerance, and adverse consequences), treat comorbid conditions (other substance use disorders, attention deficit hyperactivity disorder, anxiety, depression, and hostility), and initiate psychosocial interventions. More research on this topic will help to provide consensus on diagnostic criteria and further clarify optimal management. PMID:27338971

    Although addictive syndromes have been traditionally related to substance-use disorders, during the last few decades a novel addictive group, including the so-called "behavioral or no-drug addictions," has been recognized and has attracted increasing attention for its relevant social impact. This group includes pathological gambling, compulsive shopping, TV/Internet/social network/videogame addictions, workaholism, sex and relationship addictions, orthorexia, and overtraining syndrome. Substance and behavioral addictions show similar phenomenological features, such as craving, dependence, tolerance, and abstinence, and perhaps they share a common possible pathophysiology. It is, however, controversial whether all or at least some of them should be considered real disorders or just normal, albeit extreme, behaviors. The aim of this article is to review current data on pharmacological treatment of behavioral addictions. As no specific and validated treatment algorithms are currently available, only an improved knowledge on their psychopathological, clinical, and neurobiological features may have relevant implications for more focused preventive and therapeutic strategies.

    Full Text Available Abstract The Relapse Prevention (RP model has been a mainstay of addictions theory and treatment since its introduction three decades ago. This paper provides an overview and update of RP for addictive behaviors with a focus on developments over the last decade (2000-2010. Major treatment outcome studies and meta-analyses are summarized, as are selected empirical findings relevant to the tenets of the RP model. Notable advances in RP in the last decade include the introduction of a reformulated cognitive-behavioral model of relapse, the application of advanced statistical methods to model relapse in large randomized trials, and the development of mindfulness-based relapse prevention. We also review the emergent literature on genetic correlates of relapse following pharmacological and behavioral treatments. The continued influence of RP is evidenced by its integration in most cognitive-behavioral substance use interventions. However, the tendency to subsume RP within other treatment modalities has posed a barrier to systematic evaluation of the RP model. Overall, RP remains an influential cognitive-behavioral framework that can inform both theoretical and clinical approaches to understanding and facilitating behavior change.

    2015-05-01

    This article looks at food addiction as a subject situated between psychiatry, neurobiology, nutritional science, internal medicine, food industry, and public health. Essentially, the question is whether or not individual nutritional components can induce physical dependence, similar to the well-known effects of drugs such as alcohol and cocaine, or whether food addiction is rather a behavioral addiction. The literature describes many overlaps as well as differences of substance-based and non-substance-based addiction in both clinical and neurobiological terms. Until recently it was argued that food addiction appears only in the realms of obesity and eating disorders (e.g., binge-eating disorder, BED). Some studies, however, described the prevalence of food addiction symptoms and diagnoses independent of overweight or that they were in subjects who do not fulfill the criteria for BED. This article sums up the controversial discussion about the phenomenological and neurobiological classification of food addiction. Implications of food addiction for children and adolescents as well as public-health-related issues are also discussed.

    In this review, we highlight the role of neuroimaging techniques in studying the emotional and cognitive-behavioral components of the addiction syndrome by focusing on the neural substrates subserving them. The phenomenology of drug addiction can be characterized by a recurrent pattern of subjective experiences that includes drug intoxication, craving, bingeing, and withdrawal with the cycle culminating in a persistent preoccupation with obtaining, consuming, and recovering from the drug. In the past two decades, imaging studies of drug addiction have demonstrated deficits in brain circuits related to reward and impulsivity. The current review focuses on studies employing positron emission tomography (PET), functional magnetic resonance imaging (fMRI), and electroencephalography (EEG) to investigate these behaviors in drug-addicted human populations. We begin with a brief account of drug addiction followed by a technical account of each of these imaging modalities. We then discuss how these techniques have uniquely contributed to a deeper understanding of addictive behaviors. PMID:22117165

    Addictions are illnesses of complex causation, including inheritance and a role for gene/environment interactions. Functional alleles influencing pharmacodynamic (tissue response) and pharmacokinetic (absorption, distribution, and metabolism) play a role, but these interact with diverse environmental factors including early life stress, underage drug exposure, availability of addictive agents, and response to clinical interventions including pharmacotherapies. Identification of genetic factors in addiction thus plays an important role in the understanding of processes of addiction and origins of differential vulnerabilities and treatment responses.

    Compulsive buying behavior (CBB) has been recognized as a prevalent mental health disorder, yet its categorization into classification systems remains unsettled. The objective of this study was to assess the sociodemographic and clinic variables related to the CBB phenotype compared to other behavioral addictions. Three thousand three hundred and twenty four treatment-seeking patients were classified in five groups: CBB, sexual addiction, Internet gaming disorder, Internet addiction, and gambling disorder. CBB was characterized by a higher proportion of women, higher levels of psychopathology, and higher levels in the personality traits of novelty seeking, harm avoidance, reward dependence, persistence, and cooperativeness compared to other behavioral addictions. Results outline the heterogeneity in the clinical profiles of patients diagnosed with different behavioral addiction subtypes and shed new light on the primary mechanisms of CBB. PMID:27378999

  7. Gambling disorder and other behavioral addictions: recognition and treatment.

    Science.gov (United States)

    2015-01-01

    Addiction professionals and the public are recognizing that certain nonsubstance behaviors--such as gambling, Internet use, video-game playing, sex, eating, and shopping--bear resemblance to alcohol and drug dependence. Growing evidence suggests that these behaviors warrant consideration as nonsubstance or "behavioral" addictions and has led to the newly introduced diagnostic category "Substance-Related and Addictive Disorders" in DSM-5. At present, only gambling disorder has been placed in this category, with insufficient data for other proposed behavioral addictions to justify their inclusion. This review summarizes recent advances in our understanding of behavioral addictions, describes treatment considerations, and addresses future directions. Current evidence points to overlaps between behavioral and substance-related addictions in phenomenology, epidemiology, comorbidity, neurobiological mechanisms, genetic contributions, responses to treatments, and prevention efforts. Differences also exist. Recognizing behavioral addictions and developing appropriate diagnostic criteria are important in order to increase awareness of these disorders and to further prevention and treatment strategies.

    Aims Although relationships between addiction and personality have previously been explored, no study has ever simultaneously investigated the interrelationships between several behavioral addictions, and related these to the main dimensions of the five-factor model of personality. Methods In this study, 218 university students completed questionnaires assessing seven different behavioral addictions (i.e., Facebook addiction, video game addiction, Internet addiction, exercise addiction, mobile phone addiction, compulsive buying, and study addiction) as well as an instrument assessing the main dimensions of the five-factor model of personality. Results Of the 21 bivariate intercorrelations between the seven behavioral addictions, all were positive (and nine significantly). The results also showed that (i) Neuroticism was positively associated with Internet addiction, exercise addiction, compulsive buying, and study addiction, (ii) Extroversion was positively associated with Facebook addiction, exercise addiction, mobile phone addiction, and compulsive buying, (iii) Openness to experience was negatively associated with Facebook addiction and mobile phone addiction, (iv) Agreeableness was negatively associated with Internet addiction, exercise addiction, mobile phone addiction, and compulsive buying, and (v) Conscientiousness was negatively associated with Facebook addiction, video game addiction, Internet addiction, and compulsive buying and positively associated with exercise addiction and study addiction. Conclusions The positive associations between the seven behavioral addictions suggest one or several underlying pathological factors. Hierarchical multiple regressions showed that personality traits explained between 6% and 17% of the variance in the seven behavioral addictions, suggesting that personality to a varying degree explains scores on measures of addictive behaviors.

  12. Evolutionary and neuropsychological perspectives on addictive behaviors and addictive substances: relevance to the "food addiction" construct

    Directory of Open Access Journals (Sweden)

    Full Text Available Caroline Davis School of Kinesiology and Health Science, York University, Toronto, ON, Canada Abstract: It has been argued that food cannot be "addictive", unlike conventional drugs of abuse, because it is an essential part of life. In this paper, evidence is reviewed, largely from an evolutionary psychobiological perspective, that plant-based psychoactive drugs (such as those derived from the opium poppy and the coca leaf and gambling-related behaviors were once adaptive for human health and survival in a similar manner as energy-based foods were for nourishment. "Evolutionary mismatch" viewpoints contend that certain behaviors were enhanced during the hunter-gatherer lifestyle – from which our genetic endowment had its origins – because they bestowed both survival and reproductive advantages to the species. However, in the context of advanced technology and other rapid environmental changes, these same behaviors have tended to become maladaptive and greatly overexpressed. Similar to the manufactured purification of psychotropic plant-based substances, the reward impact of processed and hyperpalatable foods, with their high levels of sugar, fat, and salt, is much increased from foods produced in nature. It is concluded therefore that what was once beneficial and necessary for our survival has been altered and ultraprocessed into edible products that may be disadvantageous and potentially addictive.

    From a psychodynamic perspective, dependence disorders, irrespective of the object of addiction, can be seen as the expression of the subject's neurobiological, psychopathological, cultural and social vulnerability. Since vulnerability strengthens and reorganizes the personality, it can drive these subjects to perpetuate pathological behaviors. In this light, behavior disorders belong to the field of addiction diseases, especially considering that the underlying psychopathological structures are close to those observed in addiction, that depression plays a central role, and that their development into toxic addictive behavior (drugs, alcohol, psychotrope) is frequent.

    Full Text Available Objective: Determine the prevalence and compare some genetic markers involved in addictive behavior in a group of addicts to derivative of coca (cocaine/crack or heroin and a control group of non-addicted people matched for gender, age and ethnicity.Methods: A 120 addicts and 120 non-addicts Colombian male were surveyed and genotyped for 18 polymorphism of the OPRM1, DRD2, DRD4, SLC6A3, SLC6A4, ABCB1, DβH and CYP2B6 genes. For the identification of alleles markers were used mini-sequencing and fragment multiplex PCR techniques; ethnicity of cases and controls was analyzed with 61 AIMs. Results: The age of onset use of heroin or coca derivatives (cocaine/crack was 16,5±6 years and 99,2% of them consume several illicit drugs. It showed that controls and addicts belong to the same ethnic group. Significant differences between addicts and controls in relation to schooling, marital status, social security family history of substance abuse (pT ABCB1 gene (p=0,001 were found. Conclusion: The present results indicate that the VNTR-6R polymorphism of the gene SLC6A3 and the genotype 3435CC in the ABCB1 gene, are both associated with addictive behavior to heroin or cocaine.

    The easy access which modern teenagers have to new technologies favours their excessive use of video games, as they seek to escape potential existential difficulties. This harmful aspect should not mask the creative potential of games for the majority of teenagers. Treatment for young people with a gaming addiction is based on psychotherapy and takes into account the family dimension of the problem. This article presents an interview with Marc Valleur, a psychiatrist and head physician at Marmottan hospital specialising in the care and support of people with addictions.

    Addiction professionals and the public are recognizing that certain nonsubstance behaviors—such as gambling, Internet use, video-game playing, sex, eating, and shopping—bear resemblance to alcohol and drug dependence. Growing evidence suggests that these behaviors warrant consideration as nonsubstance or “behavioral” addictions and has led to the newly introduced diagnostic category “Substance-Related and Addictive Disorders” in DSM-5. At present, only gambling disorder has been placed in thi...

    Addiction coopts the brain's neuronal circuits necessary for insight, reward, motivation, and social behaviors. This functional overlap results in addicted individuals making poor choices despite awareness of the negative consequences; it explains why previously rewarding life situations and the threat of judicial punishment cannot stop drug taking and why a medical rather than a criminal approach is more effective in curtailing addiction.

    In this chapter, we briefly review the basic biology of psychological stress and the stress response. We propose that psychological stress and the neurobiology of the stress response play in substance use initiation, maintenance, and relapse. The proposed mechanisms for this include, on the one hand, the complex interactions between biological mediators of the stress response and the dopaminergic reward system and, on the other hand, mediators of the stress response and other systems crucial in moderating key addiction-related behaviors such as endogenous opioids, the sympathetic-adrenal-medullary system, and endocannabinoids. Exciting new avenues of study including genomics, sex as a moderator of the stress response, and behavioral addictions (gambling, hypersexuality, dysfunctional internet use, and food as an addictive substance) are also briefly presented within the context of stress as a moderator of the addictive process.

    2013-11-01

    Full Text Available The number of people, suffering from non-chemical addictions - workaholism, gambling, shopaholism etc. - is greatly increased during last decades. Due to the large variety of these addictions, the questions of the reasons of such behavior and its effective prevention became very urgent. Usually, these questions are tried to be solved in the field of special psychology, while the author tries to look at the problem from the position of general psychology. The paper offers the data of workaholics' addictive behavior research from the position of cultural-historical methodology and the theory of play activity's development. The goal of these study was the analysis of relations between problematic development of play in preschool age and later formation of workaholism in adult age. By using the methods of interview and writing of essay, as well as correlation and content analysis of workaholics' and non-addicts' answers, author shows that workaholics had significant underdevelopment of play in child age and also don't able to realize and/or control their play behavior in adult age. Thus, author concludes that the underdevelopment of child's play may lead to the establishment of addictive behavior and formation of addictive personality's features. Acquired data allows to provide the workaholism' prevention by the development of play in preschool age and psychotherapy of work addiction by the development of subject of play activity in adult age.DOI: http://dx.doi.org/10.12731/2218-7405-2013-9-57

    2007-10-01

    Research over the last decade has identified Internet addiction as a new and often unrecognized clinical disorder that impact a user's ability to control online use to the extent that it can cause relational, occupational, and social problems. While much of the literature explores the psychological and social factors underlying Internet addiction, little if any empirical evidence exists that examines specific treatment outcomes to deal with this new client population. Researchers have suggested using cognitive behavioral therapy (CBT) as the treatment of choice for Internet addiction, and addiction recovery in general has utilized CBT as part of treatment planning. To investigate the efficacy of using CBT with Internet addicts, this study investigated 114 clients who suffered from Internet addiction and received CBT at the Center for Online Addiction. This study employed a survey research design, and outcome variables such as client motivation, online time management, improved social relationships, improved sexual functioning, engagement in offline activities, and ability to abstain from problematic applications were evaluated on the 3rd, 8th, and 12th sessions and over a 6-month follow-up. Results suggested that Caucasian, middle-aged males with at least a 4-year degree were most likely to suffer from some form of Internet addiction. Preliminary analyses indicated that most clients were able to manage their presenting complaints by the eighth session, and symptom management was sustained upon a 6-month follow-up. As the field of Internet addiction continues to grow, such outcome data will be useful in treatment planning with evidenced-based protocols unique to this emergent client population.

    Full Text Available Factors contributing to addictive behaviors affecting student health are analyzed in this study. Smoking, alcohol consumption, and the use of illegal drugs are assessed in a sample of 290 university students. General averages indicate that 37.2% of students smoke cigarettes, 49.8% drink alcohol regularly, and 17.9% have tried illegal drugs while 4.8% of them use it regularly. Age, academic achievement, gender, religion, family status and financial status were correlated to these addictive behaviors. Major findings show a clear relationship between smoking and most variables. The main factor involved in drinking was found to be religion, while illegal drug consumption was most clearly correlated to parents’ education and monthly income. Students’ self perception regarding smoking and tendency to use illegal drug was assessed showing that 11.7% of smokers consider themselves non-smokers while 11.8% considered trying illegal drugs acceptable. Addiction rates after initial consumption are analyzed showing 74.7% for alcohol, 51.7% for smoking cigarettes and 26.9% for drugs. A risk profile for each addiction type is presented.

    2012-08-01

    Full Text Available While few studies have applied transcranial direct current stimulation (tDCS to smoking addiction, existing work suggests that the intervention holds promise for altering the complex system by which environmental cues interact with cravings to drive behavior. Imaging and repetitive transcranial magnetic stimulation (rTMS studies suggest that increased dorsolateral prefrontal cortex (DLPFC activation and integrity may be associated with increased resistance to smoking cues. Anodal tDCS of the DLPFC, believed to boost activation, reduces cravings in response to these cues. The finding that noninvasive stimulation modifies cue induced cravings has profound implications for understanding the processes underlying addiction and relapse. TDCS can also be applied to probe mechanisms underlying and supporting nicotine addiction, as was done in a pharmacologic study that applied nicotine, tDCS, and TMS paired associative stimulation to find that stopping nicotine after chronic use induces a reduction in plasticity, causing difficulty in breaking free from association between cues and cravings. This mini-review will place studies that apply tDCS to smokers in the context of research involving the neural substrates of nicotine addiction.

    2016-02-01

    Full Text Available Introduction: Behavioral addictions such as gambling, sun-tanning, shopping, internet use, work, exercise, or even love and sex are frequent, and share many characteristics and common neurobiological and genetic underpinnings with substance addictions (i.e., tolerance, withdrawal, and relapse. Recent literature suggests that both non-suicidal self-injury (NSSI and suicidal behavior (SB can also be conceptualized as addictions. The major aim of this mini review is to review the literature and explore the neurobiological and psychological mechanisms underlying the addiction to self-harming behaviors.Method: This is a narrative review. The authors performed literature searches on PubMed and Google for suicidal behavior, self-harming, addiction, and major repeaters. Given the scarce literature on the topic, a subset of the most closely related studies was selected. The authors also focused on three empirical studies testing the hypothesis that major repeaters (individuals with ≥5 lifetime suicide attempts represent a distinctive suicidal phenotype, and are the individuals at risk of developing an addiction to SB. Results: The authors reviewed the concept of behavioral addictions and major repeaters, current empirical evidence testing concerning whether or not NSSI and SB can be understood as addictions, and the putative mechanisms underlying them.Conclusion: Our review suggests that both NSSI and SB can be conceptualized as addictions. This is relevant because if some individual’s self-harming behaviors are better conceptualized as an addiction, treatment approaches could be tailored to this addiction.

    Monterosso, John; Ainslie, George

    2007-09-01

    Behavioral economic studies demonstrate that rewards are discounted proportionally with their delay (hyperbolic discounting). Hyperbolic discounting implies temporary preference for smaller rewards when they are imminent, and this concept has been widely considered by researchers interested in the causes of addictive behavior. Far less consideration has been given to the fact that systematic preference reversal also predicts various self-control phenomena, which may also be analyzed from a behavioral economic perspective. Here we summarize self-control phenomena predicted by hyperbolic discounting, particularly with application to the field of addiction. Of greatest interest is the phenomenon of choice bundling, an increase in motivation to wait for delayed rewards that can be expected to result from making choices in whole categories. Specifically, when a person's expectations about her own future behavior are conditional upon her current behavior, the value of these expectations is added to the contingencies for the current behavior, resulting in reduced impulsivity. Hyperbolic discounting provides a bottom-up basis for the intuitive learning of choice bundling, the properties of which match common descriptions of willpower. We suggest that the bundling effect can also be discerned in the advice of 12-step programs.

  7. Molecular Mechanism: ERK Signaling, Drug Addiction, and Behavioral Effects.

    Science.gov (United States)

    Sun, Wei-Lun; Quizon, Pamela M; Zhu, Jun

    2016-01-01

    Addiction to psychostimulants has been considered as a chronic psychiatric disorder characterized by craving and compulsive drug seeking and use. Over the past two decades, accumulating evidence has demonstrated that repeated drug exposure causes long-lasting neurochemical and cellular changes that result in enduring neuroadaptation in brain circuitry and underlie compulsive drug consumption and relapse. Through intercellular signaling cascades, drugs of abuse induce remodeling in the rewarding circuitry that contributes to the neuroplasticity of learning and memory associated with addiction. Here, we review the role of the extracellular signal-regulated kinase (ERK), a member of the mitogen-activated protein kinase, and its related intracellular signaling pathways in drug-induced neuroadaptive changes that are associated with drug-mediated psychomotor activity, rewarding properties and relapse of drug seeking behaviors. We also discuss the neurobiological and behavioral effects of pharmacological and genetic interferences with ERK-associated molecular cascades in response to abused substances. Understanding the dynamic modulation of ERK signaling in response to drugs may provide novel molecular targets for therapeutic strategies to drug addiction. PMID:26809997

  9. Uses of self-regulation to facilitate and restrain addictive behavior.

    Science.gov (United States)

    Baumeister, Roy F; Vonasch, Andrew J

    2015-05-01

    We apply self-regulation theory to understand addictive behavior. Self-regulation and volition depend on a limited resource, and when that resource has been depleted, self-regulation becomes prone to fail. Moving beyond traditional models that have emphasized the relevance of self-regulation to quitting addiction, we propose that self-regulation is used both to facilitate and resist addictive behaviors. Self-regulation is often needed to overcome initial aversion to drugs and alcohol, as well as to maintain addictive usage patterns despite situational obstacles (e.g., illegality, erratic availability, family disapproval). Sustaining addiction also requires preventing use from spiraling out of control and interfering with other aspects of life. More generally, the automaticity and irresistibility of addictive responses may have been overrated, as indicated by how addictive behaviors respond rationally to incentives and other concerns. Self-regulation does facilitate quitting, and relapse may be especially likely when self-regulatory capabilities are depleted. PMID:25267213

    2008-10-01

    This study aimed to a) evaluate the association between Internet addiction and problematic alcohol use; b) based on problem behavior theory, explore whether Internet addiction, as well as problematic alcohol use, correlated with the psychosocial proneness of problem behaviors among adolescents. A total of 2,114 high school students (1,204 male and 910 female) were recruited to complete the questionnaire assessing Internet addiction, problematic alcohol use, and associated psychosocial variables. The result revealed that Internet addiction was associated with problematic alcohol use. Besides, the psychosocial proneness of problem behaviors is associated with Internet addiction as well as problematic alcohol use in adolescents. These results suggest Internet addiction might be included in the organization of problem behavior theory, and it is suggested that prevention and intervention can best be carried out when grouped with other problem behaviors.

    2014-01-01

    This article reviews recent advances in the elucidation of neurobehavioral endophenotypes associated with drug addiction made possible by the translational neuroimaging techniques magnetic resonance imaging (MRI) and positron emission tomography (PET). Increasingly, these non-invasive imaging approaches have been the catalyst for advancing our understanding of the etiology of drug addiction as a brain disorder involving complex interactions between pre-disposing behavioral traits, environmental influences and neural perturbations arising from the chronic abuse of licit and illicit drugs. In this article we discuss the causal role of trait markers associated with impulsivity and novelty-/sensation-seeking in speeding the development of compulsive drug administration and in facilitating relapse.

    Four hundred seventy-nine drug abusing adolescent patients enrolled in seven Straight, Inc. Adolescent Drug-Abuse Treatment Programs in five geographic regions across the United States were studied to determine the severity and patterns of cocaine abuse. Of these, 341 admitted to cocaine use and became part of this survey. Cocaine use was categorized as heavy, intermediate, or light. Areas examined were the addictive spectrum, psychosocial dysfunction, and psychiatric symptoms. Intermediate and heavy users of cocaine abused significantly less marijuana and inhalants than light cocaine abusers. Heavy and intermediate users were more likely to use cocaine intravenously and to use crack. They developed tachyphylaxis more frequently, progressed to weekly use in less than 3 months more frequently, and became preoccupied with obtaining and using cocaine significantly more frequently. They used more sedative hypnotics to calm themselves and engaged in more criminal behavior, such as stealing from parents and stores and passing bad checks. They had more arrests for possession of drugs, stole more cars, sold more drugs, and were more likely to trade sexual favors to obtain the drug. Heavy and intermediate users were significantly more psychiatrically disturbed than light users, becoming more suspicious, nervous, aggressive, and demonstrating increased symptoms of fatigue, sleeplessness, decreased appetite, and increasing cocaine dysphoria. All of these symptoms could be mistaken for psychiatric disorders. This study suggests that cocaine is as addictive in adolescents as in adults; possibly more so. It also causes psychosocial dysfunction and psychiatric symptoms. Further research into cocaine addiction among adolescents is indicated. PMID:2582695

    The literature provides support for the hypothesis that some major repeaters (individuals with >=5 lifetime suicide attempts) are addicted to suicidal behavior (SB). This study explores whether major repeaters are addicted to SB or not using 7 criteria: tolerance (Criterion 1), withdrawal (Criterion 2), loss of control (Criterion 3), problems in quitting/cutting down (Criterion 4), much time spent using (Criterion 5), substantial reduction in activities (Criterion 6), and adverse physiological/physical consequences (Criterion 7). Total dependence on SB was indicated by the presence of 3 or more of the 7 criteria in the last 12 months. This cross-sectional study at Puerta de Hierro University Hospital (Madrid, Spain) recruited 118 suicide attempters including 8 major repeaters (7%, 8/118), who were all females. The association between each SB addiction criterion, physiological dependence and total dependence with major repeater status was tested for significance and for effect size with odds ratios (ORs) and their 95% confidence intervals. As hypothesized, major repeaters met significantly higher frequency of criteria for total dependence on SB, OR=62.9 (6.4-615). A backward stepwise logistic regression model was used to provide an OR between major repeater status and total dependence status corrected by confounding variables. Age, panic disorder without agoraphobia, borderline personality disorder, history of psychiatric inpatient admission, and total dependence on SB were introduced as independent variables with major repeater status as the dependent variable. The model selected total dependence and age as the remaining significant variables in the last step. Accordingly, major repeaters appear to be addicted to SB. PMID:25580865

    Sensation Seeking has repeatedly been related to substance use. Also, its role as a correlate of Gambling Disorder has been discussed although research has led to heterogeneous results. Likewise, first studies on Internet Addiction have indicated increased Sensation Seeking, to some extent contradicting clinical impression of patients suffering from internet addiction. We assessed Sensation Seeking in a clinical sample of n=251 patients with Gambling Disorder, n=243 patients with internet addiction, n=103 clients with excessive but not addictive internet use, and n=142 healthy controls. The clinical groups were further sub-divided according to the preferred type of addictive behavior (slot-machine gambling vs. high arousal gambling activities and internet gaming disorder vs. other internet-related addictive behaviors). Decreased scores in some subscales of Sensation Seeking were found among male patients compared to healthy controls with no differences between patients with Gambling Disorder and Internet Addiction. The type of preferred gambling or online activity was not related to differences in Sensation Seeking. Previous findings indicating only small associations between Sensation Seeking and Gambling Disorder were confirmed. Regarding Internet Addiction our results contradict findings from non-clinical samples. Sensation Seeking might be relevant in initiating contact to the health care system. PMID:27322843

    Full Text Available The purpose of this review is to discuss recent findings related to sex differences in behavioral dyscontrol that lead to drug addiction, and clinical implications for humans are discussed. This review includes research conducted in animals and humans that reveals fundamental aspects of behavioral dyscontrol. The importance of sex differences in aspects of behavioral dyscontrol, such as impulsivity and compulsivity, are discussed as major determinants of drug addiction. Behavioral dyscontrol during adolescence is also an important consideration, as this is the time of onset for drug addiction. These vulnerability factors additively increase drug abuse vulnerability, and they are integral aspects of addiction that covary and interact with sex differences. Sex differences in treatments for drug addiction are also reviewed in terms of their ability to modify the behavioral dyscontrol that underlies addictive behavior. Customized treatments to reduce behavioral dyscontrol are discussed, such as: 1 using natural consequences such as nondrug rewards (e.g., exercise to maintain abstinence, or using punishment as a consequence for drug use, 2 targeting factors that underlie behavioral dyscontrol, such as impulsivity or anxiety, by repurposing medications to relieve these underlying conditions, and 3 combining two or more novel behavioral or pharmacological treatments to produce additive reductions in drug seeking. Recent published work has indicated that factors contributing to behavioral dyscontrol are an important target for advancing our knowledge on the etiology of drug abuse, intervening with the drug addiction process and developing novel treatments.

  20. Commentary on: Are we overpathologizing everyday life? A tenable blueprint for behavioral addiction research.

    Blaszczynski, Alexander

    2015-09-01

    This commentary supports the argument that there is an increasing tendency to subsume a range of excessive daily behaviors under the rubric of non-substance related behavioral addictions. The concept of behavioral addictions gained momentum in the 1990s with the recent reclassification of pathological gambling as a non-substance behavioral addiction in DSM-5 accelerating this process. The propensity to label a host of normal behaviors carried out to excess as pathological based simply on phenomenological similarities to addictive disorders will ultimately undermine the credibility of behavioral addiction as a valid construct. From a scientific perspective, anecdotal observation followed by the subsequent modification of the wording of existing substance dependence diagnostic criteria, and then searching for biopsychosocial correlates to justify classifying an excessive behavior resulting in harm as an addiction falls far short of accepted taxonomic standards. The differentiation of normal from non-substance addictive behaviors ought to be grounded in sound conceptual, theoretical and empirical methodologies. There are other more parsimonious explanations accounting for such behaviors. Consideration needs to be given to excluding the possibility that excessive behaviors are due to situational environmental/social factors, or symptomatic of an existing affective disorder such as depression or personality traits characteristic of cluster B personalities (namely, impulsivity) rather than the advocating for the establishment of new disorders.

  1. Toward quantifying the abuse liability of ultraviolet tanning: A behavioral economic approach to tanning addiction.

    Many adults engage in ultraviolet indoor tanning despite evidence of its association with skin cancer. The constellation of behaviors associated with ultraviolet indoor tanning is analogous to that in other behavioral addictions. Despite a growing literature on ultraviolet indoor tanning as an addiction, there remains no consensus on how to identify ultraviolet indoor tanning addictive tendencies. The purpose of the present study was to translate a behavioral economic task more commonly used in substance abuse to quantify the "abuse liability" of ultraviolet indoor tanning, establish construct validity, and determine convergent validity with the most commonly used diagnostic tools for ultraviolet indoor tanning addiction (i.e., mCAGE and mDSM-IV-TR). We conducted a between-groups study using a novel hypothetical Tanning Purchase Task to quantify intensity and elasticity of ultraviolet indoor tanning demand and permit statistical comparisons with the mCAGE and mDSM-IV-TR. Results suggest that behavioral economic demand is related to ultraviolet indoor tanning addiction status and adequately discriminates between potential addicted individuals from nonaddicted individuals. Moreover, we provide evidence that the Tanning Purchase Task renders behavioral economic indicators that are relevant to public health research. The present findings are limited to two ultraviolet indoor tanning addiction tools and a relatively small sample of high-risk ultraviolet indoor tanning users; however, these pilot data demonstrate the potential for behavioral economic assessment tools as diagnostic and research aids in ultraviolet indoor tanning addiction studies.

    To investigate the model of pedophilia as a disorder of addictive behavior, pedophiles and chemically addicted individuals were compared on personality traits potentially associated with impaired behavioral inhibition. Twenty-nine pedophiles, 25 opiate addicts (OA's), and 27 healthy controls were administered the Barratt Impulsivity Scale, Hare Psychopathy Checklist-Revised (PCL-R), and Structured Clinical Interview for DSM-V for Axis-II. OA's scored higher than either pedophiles or controls on the Barratt. Pedophiles and OA's scored higher than controls on all 3 Psychopathy Checklist-Revised scores but OA's scored marginally higher than pedophiles on factor 2 (behavioral) and total scores. On Structured Clinical Interview for DSM-V for Axis-II, pedophiles scored higher than controls on paranoid and schizoid scores whereas OA's did so on paranoid scores. Thus, both pedophiles and OA's may have elevated psychopathic traits and propensity toward cognitive distortions, as reflected in cluster A traits. Such similarities support the conceptualization of pedophilia as a behavioral addiction. Pedophiles may be less impulsive than OA's, however, and more prone toward cognitive distortions.

    Internet addiction has become a serious behavioral health problem in Asia. However, there are no up-to-date country comparisons. The Asian Adolescent Risk Behavior Survey (AARBS) screens and compares the prevalence of Internet behaviors and addiction in adolescents in six Asian countries. A total of 5,366 adolescents aged 12-18 years were recruited from six Asian countries: China, Hong Kong, Japan, South Korea, Malaysia, and the Philippines. Participants completed a structured questionnaire on their Internet use in the 2012-2013 school year. Internet addiction was assessed using the Internet Addiction Test (IAT) and the Revised Chen Internet Addiction Scale (CIAS-R). The variations in Internet behaviors and addiction across countries were examined. The overall prevalence of smartphone ownership is 62%, ranging from 41% in China to 84% in South Korea. Moreover, participation in online gaming ranges from 11% in China to 39% in Japan. Hong Kong has the highest number of adolescents reporting daily or above Internet use (68%). Internet addiction is highest in the Philippines, according to both the IAT (5%) and the CIAS-R (21%). Internet addictive behavior is common among adolescents in Asian countries.

    2012-09-01

    Recently, there have been growing concerns about excessive online gaming. Playing Massively Multiplayer Online Role-Playing Games (MMORPGs) appears to be particularly problematic, because these games require a high degree of commitment and time investment from the players to the detriment of occupational, social, and other recreational activities and relations. A number of gaming motives have been linked to excessive online gaming in adolescents and young adults. We assessed 175 current MMORPG players and 90 nonplayers using a Web-based questionnaire regarding their gaming behavior, problems as consequences of gaming, and game motivations and tested their statistical associations. Results indicated that (a) MMORPG players are significantly more likely to experience gaming-related problems relative to nonplayers, and that (b) the gaming motivations escapism and mechanics significantly predicted excessive gaming and appeared as stronger predictors than time investment in game. The findings support the necessity of using measures that distinguish between different types of online games. In addition, this study proves useful regarding the current discussion on establishing (online) gaming addiction as a diagnosis in future categorizations of psychopathology.

    Internet addiction disorder (IAD) has raised widespread public health concerns. In this study, we used a gambling task to simulate extreme win/lose situations to find the reward/punishment sensitivities after continuous wins and losses. FMRI data were collected from 16 IAD subjects (21.4±3.1years) and 15 healthy controls (HC, 22.1±3.6years). Group comparisons showed higher superior frontal gyrus activations after continuous wins for IAD subjects than for HC. The brain activities in IAD subjects were not disturbed by their losses. In addition, IAD participants showed decreased posterior cingulate activation compared to HC after continuous losses. These results indicated that IAD participants showed preference to win while neglecting their losses. Therefore they engaged less executive endeavor to control their frustration after continuous losses. Taken together, we concluded that IAD subjects showed enhanced sensitivity to win and decreased sensitivity to lose. This can help us understand why IAD subjects continue playing online even after noticing the severe negative consequences of their behaviors.

    Full Text Available Objective: This study aimed to study/understand sexual risk behaviors and the perception of occupational competence in drug addicts, regarding the existence/absence of Sexually Transmitted Diseases (STD. Method: We opted for a quantitative and transversal methodology that provided an exploratory and descriptive nature to the study. To this end, 166 drug addicts aged 34.6 years on average were assessed through the following questionnaires: “Occupational Self Assessment” and “HIV-KQ”. Results: Regarding sexual behaviors, drug addicts infected with HIV were the group using condoms more frequently and having a more comprehensive knowledge about HIV. On the other hand, drug addicts with no STDs presented higher median scores related to occupational competence, volition, and performance ability when compared with the other two groups. Conclusions: Sexual risk behaviors among drug addicts differ according to their serology. Drug addicts without STD maintain sexual risk behaviors. They seem to have no perception of how serious the fact of being infected with HIV is to their health and occupational ability. When a drug addict is confronted with his own seropositivity to HIV, there seems to be a common behavior related to the use of precautions (condoms, risk reduction in every type of sexual relation, and decreased perception of occupational competence.

Whilst these 'theories of addiction' disagree about importance and/or nature of a number of key psychological processes (e.g. the necessity of craving and/or the involvement of drug-value representations), a number of commonalities exist. For instance, it is widely accepted that Pavlovian associations between cues and environmental contexts and the drug effects acquired over the course of addiction play a critical role, especially in relapse vulnerability in detoxified addicts. Additionally, all theories of addiction (explicitly or implicitly) propose that chronic drug exposure produces persistent neuroplastic changes in neurobiological circuitries underlying critical emotional, cognitive and motivational processes, although disagreement exists as to the precise nature of these neurobiological changes and/or their psychological consequences. The present review, rather than limiting itself to any particular theoretical stance, considers various candidate psychological, neurobiological and/or behavioral processes in addiction and outlines conceptual and procedural approaches for the experimental medicine laboratory. The review discusses (1) extinction, renewal and (re)consolidation of learned associations between cues and drugs, (2) the drug reward value, (3) motivational states contributing to drug seeking and (4) reflective (top-down) and sensory (bottom-up) driven decision-making. In evaluating these psychological and/or behavioral processes and their relationship to addiction we make reference to putative underlying brain structures identified by basic animal studies and/or imaging studies with humans.

    Excessive and potentially addictive use of the Internet among children and adolescents has emerged as a major concern in recent times. Internet addiction is often conceptualized as an impulse control disorder, with features similar to pathological gambling. However, there remains considerable debate about the core components, etiological processes, course, and maintaining factors of the disorder. This article presents a case study of a 16-year-old male with generalized pathological Internet use. Critical issues relevant to case conceptualization, assessment, and choice of therapy are examined. Although the evidence base is limited in this emerging area of clinical psychology, we provide a summary of empirically supported cognitive-behavioral techniques for Internet addiction.

    Behavioral addictions (BAs) are underrecognized, even in addiction programs. We assessed BAs in a substance abuse sample (n = 51; data collection 2011-2012). A self-report Behavioral Addictions Screen, assessing eight BAs, was administered using an automated telephone system. Most endorsed at least one BA, with the most common shopping/spending; eating; work; computer/internet; and sex/pornography. Lowest were gambling, self-harm, and exercise. Some BAs were correlated with others. Gender, ethnicity, age, and positive depression and posttraumatic stress disorder screens were associated with specific BAs. Future research could address interpretation of "addiction," comparison to diagnostic interviews, relationship to substance use disorders, and larger samples. PMID:24304172

    In humans, adolescence is a period of heightened propensity to develop cocaine addiction. It is unknown whether this is attributable to greater access and exposure to cocaine at this age, or whether the adolescent brain is particularly vulnerable to the addictive properties of cocaine. Here, we subjected male adolescent (P42) and adult (~P88) rats to a wide range of cocaine self-administration procedures. In addition, to determine whether behavioral differences are associated with development...

    Introduction: Internet addiction is a typical use of the internet that causes the psychological, social, educational, or occupational problems for the people. Students need the internet more than other people due to their educational or research needs. The rate and type of the internet use may affect their information-seeking behavior too. This study aims to investigate the effect of the internet addiction on the information-seeking behavior of the postgraduate students. Methods: This applied study that uses the correlation method. The research population composed of 1149 postgraduate students of Isfahan University of Medical Sciences, of which 284 were selected using the stratified random sampling as the sample. Yang’s internet addiction questionnaire and the researcher-developed questionnaire of the information-seeking behavior were used as the data collection instruments. Instrument validity was confirmed by the specialists of librarianship and medical sciences and its reliability was confirmed using the Cronbach’s alpha coefficient (0.86). Research data were analyzed using the descriptive statistics (mean and standard deviation) and inferential statistics (independent-t tests, Pearson correlation coefficient, and variance analysis). Results: Based on the findings, there was no sign of internet addiction among the 86.6% of the students. However, 13% of the students were exposed to the internet addiction and only 0.4% of internet addiction was observed among the students. There was no significant difference between the information-seeking behavior of the male and female respondents. There was no sign of the internet addiction in any dimension of the information-seeking behavior of the students. Conclusion: This study showed that there is no relationship between the information-seeking behavior of the students and the age and the rate of the internet use. Promoting the network infrastructures and increasing the internet speed as well as facilitating the use of

  6. A narrative review of binge eating and addictive behaviors: Shared associations with seasonality and personality factors

    Full Text Available Binge eating disorder (BED and seasonal affective disorder (SAD were first described as clinically-relevant conditions in very close temporal proximity a few decades ago. Both disorders have a higher prevalence rate in woman than in men, are characterized by a high proneness-to-stress and manifest heightened responsiveness to high-calorie, hyper-palatable foods. In recent years, a compelling body of evidence suggests that foods high in sugar and fat have the potential to alter brain reward circuitry in a manner similar to that seen when addictive drugs like alcohol and heroin are consumed in excess. These findings have led to suggestions that some cases of compulsive overeating may be understood as an addiction to sweet, fatty, and salty foods. In this paper, it is proposed that high seasonality is a risk factor for binge eating, especially in those characterized by anxious and impulsive personality traits – associations that could only occur in an environment with a superfluity of, and easy access to, rich and tasty foods. Given the well-established links between binge eating and addiction disorders (22-24 for reviews, it is also suggested that seasonality, together with the same high-risk psychological profile, exacerbates the likelihood of engaging in a broad range of addictive behaviors. Data from a community sample (n=412 of adults tested these models using linear regression procedures. Results confirmed that symptoms of binge eating and other addictive behaviors were significantly inter-correlated, and that seasonality, gender, and addictive personality traits were strong statistical predictors of the variance in binge-eating scores. Seasonality and addictive personality traits also accounted for a significant proportion of the variance in the measure of addictive behaviors. Conclusions are discussed in the context of brain reward mechanisms, motivational alternations in response to chronic over-consumption, and their relevance for the

    An increasing perspective conceptualizes obesity and overeating as disorders related to addictive-like processes that could share common neurobiological mechanisms. In the present study, we aimed at validating an animal model of eating addictive-like behavior in mice, based on the DSM-5 substance use disorder criteria, using operant conditioning maintained by highly palatable chocolate-flavored pellets. For this purpose, we evaluated persistence of food-seeking during a period of non-availability of food, motivation for food, and perseverance of responding when the reward was associated with a punishment. This model has allowed identifying extreme subpopulations of mice related to addictive-like behavior. We investigated in these subpopulations the epigenetic and proteomic changes. A significant decrease in DNA methylation of CNR1 gene promoter was revealed in the prefrontal cortex of addict-like mice, which was associated with an upregulation of CB1 protein expression in the same brain area. The pharmacological blockade (rimonabant 3 mg/kg; i.p.) of CB1 receptor during the late training period reduced the percentage of mice that accomplished addiction criteria, which is in agreement with the reduced performance of CB1 knockout mice in this operant training. Proteomic studies have identified proteins differentially expressed in mice vulnerable or not to addictive-like behavior in the hippocampus, striatum, and prefrontal cortex. These changes included proteins involved in impulsivity-like behavior, synaptic plasticity, and cannabinoid signaling modulation, such as alpha-synuclein, phosphatase 1-alpha, doublecortin-like kinase 2, and diacylglycerol kinase zeta, and were validated by immunoblotting. This model provides an excellent tool to investigate the neurobiological substrate underlying the vulnerability to develop eating addictive-like behavior.

    A survey of 2,095 college students in five major cities in China was conducted to examine the influence of personality, parental behaviors, and self-esteem on Internet addiction. We found that psychoticism and neuroticism were both positively related to Internet addiction. The influence of parental behaviors on Internet addition was also significant. However, fathers' and mothers' behaviors had different impacts on their children's likelihood of being addicted to the Internet. Specifically, we found that fathers' rejection and overprotection, and mothers' rejection would increase the risk for Internet addiction. Furthermore, the influence of emotional warmth from parents on Internet addiction was partially mediated by self-esteem. Finally, we found that parental behaviors of mothers and fathers affected males and females differently in terms the risk of being addicted to the Internet.

  10. Commentary on: Are we overpathologizing everyday life? A tenable blueprint for behavioral addiction research. On the slippery slopes: The case of gambling addiction.

    Science.gov (United States)

    Clark, Luke

    2015-09-01

    Billieux et al. (2015) propose that the recent proliferation of behavioral addictions has been driven by deficiencies in the underlying research strategy. This commentary considers how pathological gambling (now termed gambling disorder) traversed these challenges to become the first recognized behavioral addiction in the DSM-5. Ironically, many similar issues continue to exist in research on gambling disorder, including question-marks over the validity of tolerance, heterogeneity in gambling motives, and the under-specification of neuroimaging biomarkers. Nevertheless, I contend that the case for gambling disorder as a behavioral addiction has been bolstered by the existence of clear and consistent functional impairment (primarily in the form of debt), coupled with the development of a public health approach that has given emphasis to product features (i.e. the structural characteristics of gambling forms) as much as individual dispositions (the 'addictive personality').

    Zhou, Yan; Leri, Francesco

    2016-01-01

    Opiate addiction, similarly to addiction to other psychoactive drugs, is chronic relapsing brain disease caused by drug-induced short-term and long-term neuroadaptations at the molecular, cellular, and behavioral levels. Preclinical research in laboratory animals has found important interactions between opiate exposure and stress-responsive systems. In this review, we will discuss the dysregulation of several stress-responsive systems in opiate addiction: vasopressin and its receptor system, endogenous opioid systems (including proopiomelanocortin/mu opioid receptor and dynorphin/kappa opioid receptor), orexin and its receptor system, and the hypothalamic-pituitary-adrenal axis. A more complete understanding of how opiates alter these stress systems, through further laboratory-based studies, is required to identify novel and effective pharmacological targets for the long-term treatment of heroin addiction.

    2015-01-01

    We reviewed the cognitive and neurobiological commonalities between chemical and behavioral addictions. Poor impulse control, limited executive function and abnormalities in reward processing are seen in both group of entities. Brain imaging shows consistent abnormalities in frontoparietal regions and the limbic system. In drug addiction, exaggerated risk taking behavior and temporal discounting may reflect an imbalance between a hyperactive mesolimbic and hypoactive executive systems. Several cognitive distortions are found in pathological gambling that seems to harness the brain reward system that has evolved to face situations related to skill, not random chance. Abnormalities in risk assessment and impulsivity are found in variety of eating disorders, in particularly related to eating behavior. Corresponding findings in eating disorder patients include abnormalities in the limbic system, i.e. orbitofrontal cortex (OFC), striatum and insula. Similarly, internet addiction disorder is associated with risky decision making and increased choice impulsivity with corresponding discrepant activation in the dorsolateral prefrontal cortex, OFC, anterior cingulate cortex, caudate and insula. Sexual addictions are in turn associated with exaggerated impulsive choice and suggestive evidence of abnormalities in reward processing. In sum, exploration of executive function and decision making abnormalities in chemical and behavioral addictions may increase understanding in their psychopathology and yield valuable targets for therapeutic interventions.

  15. Studying the factors in dependency to substances changing the mood and behavior and effective methods in drug addiction counseling

    Directory of Open Access Journals (Sweden)

    2004-05-01

    Full Text Available Addicts to alcohol and other substances changing the mood and behavior attempt to stop their addiction and avoid its relapse because they suffer mental and physical problems, they are under the pressure of family members, employer and other individuals who influence over their life as well as negative effects of drug addiction on their performance in family, work and social relations. Since drug addicts experience physical pain when they are not using drugs, they refer, at first, to physicians and then to psychiatrists. Although emerging and applying non-medical and non-pharmaceutical approaches models is not too old, arising various addictive drugs and increasing the number of drug addicts as well as individual/social destructive consequences of drug addiction have caused that psychiatrists, psychologists and social workers to represent various non-pharmaceutical theories, models, methods and guidelines based on the conditions of their clients and their clinical experiences. The present article attempts to identify the reasons of drug addiction tendency, consumption patterns, models, theories of addiction to substances changing the mood and behavior, various methods of drug treatment, effective methods in drug addiction counseling and non-medical and non-pharmaceutical methods to give up drug addiction by using recent research findings. On this basis, the most effective methods to help those who suffer from alcohol and other drugs abuse and dependency are studied.

    Full Text Available : This study aimed to investigate the effectiveness of group cognitive-behavioral therapy on aggression among addicts. Method: A quasi-experimental design along with pre-posttest stages, control group, and follow-up was employed for the conduct of this study. The number of 24 addicts referring to rehabilitation clinics in Tehran was selected as the sample size of this study via convenience sampling method in accordance with the inclusion criteria. These participants were randomly assigned to experimental and control groups. In this study, Buss-Perry Aggression Questionnaire was used for data collection purposes. Results: Data analysis showed that group cognitive-behavioral therapy reduces verbal and physical aggression, anger, and hostility in addicted people. However, this therapy only led to the reduction of verbal aggression, anger, and hostility in addicted people. Conclusion: Since aggression has a high comorbidity with substance abuse, this factor can be as an obstacle to withdrawal. Therefore, it must be considered in addiction treatment.

    Most tests of video game addiction have weak construct validity and limited ability to correctly identify people in denial. The purpose of the present research was to investigate the reliability and validity of a new test of video game addiction (Behavioral Addiction Measure-Video Gaming [BAM-VG]) that was developed in part to address these deficiencies. Regular adult video gamers (n = 506) were recruited from a Canadian online panel and completed a survey containing three measures of excessive video gaming (BAM-VG; DSM-5 criteria for Internet Gaming Disorder [IGD]; and the IGD-20), as well as questions concerning extensiveness of video game involvement and self-report of problems associated with video gaming. One month later, they were reassessed for the purposes of establishing test-retest reliability. The BAM-VG demonstrated good internal consistency as well as 1 month test-retest reliability. Criterion-related validity was demonstrated by significant correlations with the following: time spent playing, self-identification of video game problems, and scores on other instruments designed to assess video game addiction (DSM-5 IGD, IGD-20). Consistent with the theory, principal component analysis identified two components underlying the BAM-VG that roughly correspond with impaired control and significant negative consequences deriving from this impaired control. Together with its excellent construct validity and other technical features, the BAM-VG represents a reliable and valid test of video game addiction.

    The aim of this study was to determine secondary school students' levels of Internet addiction and the physical and psychosocial behavior problems they face while using the Internet. This descriptive study was conducted in three state secondary schools in a rural area in the western part of Turkey. This study's sample consisted of 549 students who agreed to participate, with the consent of their families, and who had an Internet connection at home. The data were evaluated using t-tests and variance analyses. In this study the students' score of Internet addiction was at medium level (mean addiction score 44.51 ± 17.90). There were significant differences between the students' Internet addiction scores and the presence of physical behavior problems (going to bed late, skipping meals, eating meals in front of the computer) and psychosocial behavior problems (suffering from conditions such as restlessness, anger, heart palpitations, or tremors when they could not connect to the Internet, decreased relationships with family and friends, feelings of anger, arguing with parents, and finding life boring and empty without an Internet connection).

    Global treatment of drug addiction costs society billions of dollars annually, but current psychopharmacological therapies have not been successful at desired rates. The increasing number of individuals suffering from substance abuse has turned attention to what makes some people more vulnerable to drug addiction than others. One personality trait that stands out as a contributing factor is novelty seeking. Novelty seeking, affected by both genetic and environmental factors, is defined as the tendency to desire novel stimuli and environments. It can be measured in humans through questionnaires and in rodents using behavioral tasks. On the behavioral level, both human and rodent studies demonstrate that high novelty seeking can predict the initiation of drug use and a transition to compulsive drug use and create a propensity to relapse. These predictions are valid for several drugs of abuse, such as alcohol, nicotine, cocaine, amphetamine, and opiates. On the molecular level, both novelty seeking and addiction are modulated by the central reward system in the brain. Dopamine is the primary neurotransmitter involved in the overlapping neural substrates of both parameters. In sum, the novelty-seeking trait can be valuable for predicting individual vulnerability to drug addiction and for generating successful treatment for patients with substance abuse disorders.

    Uncontrolled use of the internet has been reported to affect the lives of some users in a negative way. According to epidemiological studies, about 1% of the general population is showing signs of internet addiction. Since internet addiction is becoming a growing health concern, research on potential risk factors is becoming more important in order to develop strategies for prevention and to adopt therapeutic treatment. Although there are some studies investigating personality traits in internet addiction, most of these studies are based on samples of healthy subjects. In this research project, we compared personality profiles of a sample of patients in different rehabilitation centers. 70 patients with an addiction disorder that additionally met the criteria for internet addiction were compared to 48 patients suffering from alcohol dependence. Besides Big Five personality traits, we also assessed depressive symptoms. It was shown that patients with comorbid internet addiction can be discriminated from other patients by higher neuroticism and lower extraversion as well as lower conscientiousness. After controlling for depressive symptoms, lower conscientiousness especially turned out to be a disorder-specific risk factor. As internet addiction is related to unique patterns of personality traits and can be discriminated from alcohol dependence, treatment approaches are needed that meet the specific requirements of patients with internet addiction.

    Clinical and experimental observations show individual differences in the development of addiction. Increasing evidence supports the hypothesis that dopamine receptor availability in the nucleus accumbens (NAc) predisposes drug reinforcement. Here, modeling striatal-midbrain dopaminergic circuit, we propose a reinforcement learning model for addiction based on the actor-critic model of striatum. Modeling dopamine receptors in the NAc as modulators of learning rate for appetitive--but not aversive--stimuli in the critic--but not the actor--we define vulnerability to addiction as a relatively lower learning rate for the appetitive stimuli, compared to aversive stimuli, in the critic. We hypothesize that an imbalance in this learning parameter used by appetitive and aversive learning systems can result in addiction. We elucidate that the interaction between the degree of individual vulnerability and the duration of exposure to drug has two progressive consequences: deterioration of the imbalance and establishment of an abnormal habitual response in the actor. Using computational language, the proposed model describes how development of compulsive behavior can be a function of both degree of drug exposure and individual vulnerability. Moreover, the model describes how involvement of the dorsal striatum in addiction can be augmented progressively. The model also interprets other forms of addiction, such as obesity and pathological gambling, in a common mechanism with drug addiction. Finally, the model provides an answer for the question of why behavioral addictions are triggered in Parkinson's disease patients by D2 dopamine agonist treatments. PMID:20569176

Over time, drug use causes atrophy in prefrontally mediated cognitive control networks and hijacks striatal circuits devoted to processing natural rewards in service of compulsive seeking of drug-related reward. In essence, mindfulness-based interventions (MBIs can be conceptualized as mental training programs for exercising, strengthening, and remediating these functional brain networks. This review describes how MBIs may remediate addiction by regulating frontostriatal circuits, thereby restoring an adaptive balance between these top-down and bottom-up processes. Empirical evidence is presented suggesting that MBIs facilitate cognitive control over drug-related automaticity, attentional bias, and drug cue reactivity, while enhancing responsiveness to natural rewards. Findings from the literature are incorporated into an integrative account of the neural mechanisms of mindfulness-based therapies for effecting positive behavior change in the context of addiction recovery. Implications of our theoretical framework are presented with respect to how these insights can inform the addiction therapy process.

    Plastic changes in the nucleus accumbens (NAcc), a structure occupying a key position in the neural circuitry related to motivation, are among the critical cellular processes responsible for drug addiction. During the last decade, it has been shown that memory formation and related neuronal plasticity may rely not only on protein synthesis but also on protein degradation by the ubiquitin proteasome system (UPS). In this study, we assess the role of protein degradation in the NAcc in opiate-related behaviors. For this purpose, we coupled behavioral experiments to intra-accumbens injections of lactacystin, an inhibitor of the UPS. We show that protein degradation in the NAcc is mandatory for a full range of animal models of opiate addiction including morphine locomotor sensitization, morphine conditioned place preference, intra-ventral tegmental area morphine self-administration and intra-venous heroin self-administration but not for discrimination learning rewarded by highly palatable food. This study provides the first evidence of a specific role of protein degradation by the UPS in addiction.

    Event-related potential studies of cognitive function in addiction behaviors have focused on the P300 event-related potential component. The current study investigated the association between P300 component and Internet addiction disorder. We found that individuals with Internet addiction disorder exhibited significantly longer P300 latencies than controls (N2: P = 0.035; P3a: P = 0.031; P3b: P = 0.043) and similar P300 amplitudes compared to control participants. After 3 months of cognitive behavioral therapy, P300 latencies decreased significantly in the P3a and P3b (P3a: P = 0.045; P3b: P = 0.062). These results suggest that deficits in cognitive function may be involved in Internet addiction disorder, and that clinical psychological treatment may be effective.

    Background and aims Research indicates that excessive pornography use can negatively impact romantic relationships. However, it is unclear whether these negative outcomes are different than negative outcomes produced by other compulsive or addictive behaviors, such as drug use. This study compared perceptions of relationship outcomes from either a romantic partner's excessive marijuana or pornography use. Furthermore, this study experimentally manipulated four factors potentially related to perceptions of relationship satisfaction and addictive behavior. Methods A total of 186 college-aged women read 16 scenarios describing heterosexual romantic relationships in which one partner used either pornography or marijuana. Each scenario varied on four variables: relationship commitment, secrecy of partner's behavior, frequency of partner's behavior, and context of partner's behavior. Results Results suggest that partner pornography and marijuana use are perceived to impact romantic relationships similarly and are influenced by similar factors, such as greater frequency, higher secrecy, and partner's availability for interaction. Conclusions Such findings are consistent with recommendations by professionals that compulsive pornography use be considered worthy of treatment intervention. PMID:26165604

    Full Text Available Objective: The craving is a strong desire to consume a psychotropic substance and is one of the symptoms of withdrawal syndrome in drug addiction. As a theoretical construct, craving is complex and described by different authors, which results in various theoretical models, but there is a consensus on the importance of its treatment. This paper conducted a literature review to identify and describe the most widely used techniques of Cognitive Behavior Therapy for the management of craving and to verify the impact of applying these techniques on outcome variables, specifically the craving. Method: Searches were conducted in the databases of PubMed and PsycInfo using the following descriptors in association: “craving”, “cognitive therapy” “behavior therapy” and “cognitive behavior therapy”. Results: 198 papers were found, out of which thirty four were selected for analysis. The cognitive behavior therapy treatment includes various techniques such as Relapse Prevention, Psychoeducational, Humor and Stress Management, Motivational Interviewing, Exposure to the Relapse Prevention and Relaxation techniques. The manual for Project MATCH is one of the most cited and used for the treatment of drug addicts. Cue Exposure Therapy (CET, Attentional Bias Modification (ABM and newer “mindfulness” therapeutic methods are studied, and have shown promising results, but still need to be further investigated. Conclusion: Various treatments have been proposed and have allowed the achievement of significant improvements in the reduction of craving.

    Full Text Available Impulsivity is tightly linked to addiction. However, there are several pathways by means of which impulsive individuals are more prone to become addicts, or to suffer an addiction more intensely and for a longer period. One of those pathways involves an inadequate appraisal or regulation of positive and negative emotions, leading to lack of control over hazardous behaviors, and inappropriate decisions. In the present work, we assessed cocaine-dependent individuals (CDI; n=20, pathological gamblers (PG; n=21, and healthy controls (HC; n=23 in trait impulsivity measures (UPPS-P model’s dimensions, and decision-making tasks (Go/No-go; delay-discounting task. During the Go/No-go task, electroencephalographic (EEG activity was recorded, and Go/No-go stimuli-evoked potentials (ERP were extracted. Theory-driven ERP analyses focused on the No Go > Go difference in the N2 ERP.Our results show that negative urgency is one of the several psychological features that distinguish addicts from healthy controls. Nevertheless, among the measures of trait impulsivity, negative urgency is unique at independently covarying with gambling over-pathologization in the PG sample. Cocaine dependent individuals performed more poorly than gamblers in the Go/No-go task, and showed abnormal Go/no-go stimuli-evoked potentials. The difference between the No-go stimulus-evoked N2, and the Go one was attenuated by severity and intensity of chronic cocaine use. Emotional dimensions of impulsivity, however, did not influence go/No-go performance.

    There is high comorbidity between stress-related psychiatric disorders and addiction, suggesting they may share one or more common neurobiological mechanisms. Because of its role in both depressive and addictive behaviors, the galanin system is a strong candidate for such a mechanism. In this study, we tested if galanin and its receptors are involved in stress-associated behaviors and drug addiction. Mice were exposed to 21 days of chronic restraint stress (CRS); subsequently, mRNA levels of galanin, galanin receptors (GalRs), the rate-limiting enzymes for the synthesis of monoamines, and monoamine autoreceptors were measured in the nucleus accumbens by a quantitative real-time polymerase chain reaction. Moreover, we tested the effects of this stress on morphine-induced addictive behaviors. We found that CRS induced anxiety and depression-like behaviors, impaired the formation and facilitated the extinction process in morphine-induced conditioned place preference (CPP), and also blocked morphine-induced behavioral sensitization. These behavioral results were accompanied by a CRS-dependent increase in the mRNA expression of galanin, GalR1, tyrosine hydroxylase (TH), tryptophan hydroxylase 2, and 5-HT1B receptor. Interestingly, treatment with a commonly used antidepressant, fluoxetine, normalized the CRS-induced behavioral changes based on reversing the higher expression of galanin and TH while increasing the expression of GalR2 and α2A-adrenceptor. These results indicate that activating the galanin system, with corresponding changes to noradrenergic systems, following chronic stress may modulate stress-associated behaviors and opiate addiction. Our findings suggest that galanin and GalRs are worthy of further exploration as potential therapeutic targets to treat stress-related disorders and drug addiction.

    Cue exposure techniques have been increasingly applied in the treatment of addictive behaviors. The role of cue exposure in a comprehensive approach to relapse prevention is considered from several theoretical perspectives. Issues discussed include the optimal definition of both cue and response variables in cue exposure, the relation between exposure to drug-taking cues and elicitation of outcome expectancies, and the combination of extinction-based cue exposure methods and skill training in relapse prevention programs. Whether cue exposure effects are mediated by extinction of appetitive craving responses and/or by the modification of efficacy and outcome expectancies is discussed. PMID:2248112

    Eating patterns that lead to overconsumption of high fat, high sugar (HFHS) foods share similar features with addictive behaviors. Application of addiction paradigms, such as stress inductions, cue reactivity and behavioral economic assessments, to the study of motivation for HFHS food consumption may be a promising means of understanding food consumption. To date, few studies have investigated the interaction of stress and environmental cues on craving, and no study leveraged the state relative reinforcing value of foods (RRVfood) under varying conditions of affective states, the foci of the current study. This study used a mixed factorial design (Mood Induction: Neutral, Stress; Cues: Neutral, Food) with repeated measures on time (Baseline, Post-Mood Induction, Post-Cue Exposure). Participants (N = 133) were community adults who endorsed liking of HFHS snacks but denied eating pathology. The primary DVs were subjective craving and RRVfood. Negative and positive affect (NA, PA), the amount of food consumed, and latency to first bite were also examined. Participants in the Stress condition reported no change in craving or RRVfood. Exposure to food cues significantly increased participants' craving and RRVfood, but an interaction of stress and cues was not present. Participants did not differ on how many calories they consumed based on exposure to stress or food cues, but participants in the food cues condition had a shorter latency to the first bite of food. This study highlights the importance of environmental cues in food motivation. It also demonstrates the utility of using RRVfood to further characterize food motivation. PMID:26022802

  2. Pavlovian conditioning and cross-sensitization studies raise challenges to the hypothesis that overeating is an addictive behavior.

    Elevated glucocorticoid levels and sign tracking (ST) in Pavlovian conditioning are potential biomarkers of compulsive behaviors such as addiction. As overeating is sometimes viewed as a form of addictive behavior, we hypothesized that murine Pavlovian sign trackers would have a greater propensity to overeat and develop obesity. Using a food reward in the classical conditioning paradigm, we show that ST behavior is a robust conditioned response but not a predictor of eating and growth trajectories in mice, thus challenging the view that the development of obesity and drug addiction depend on identical mechanisms. This interpretation was supported by experiments which showed that overweight mice do not display cross-sensitization to an addictive drug (morphine), and conversely, that overweight morphine-sensitized animals do not overconsume a highly rewarding food. Although the rewarding/motivational effects of both food and drugs of abuse are mediated by similar neurochemical mechanisms, obesity and drug addiction represent a summation of other dysfunctional input and output pathways that lead to the emergence of two distinct disorders, each of which would deserve a specific pharmacotherapeutic approach.

    The purpose of this study was to identify personality factor-associated predictors of smartphone addiction predisposition (SAP). Participants were 2,573 men and 2,281 women (n = 4,854) aged 20-49 years (Mean ± SD: 33.47 ± 7.52); participants completed the following questionnaires: the Korean Smartphone Addiction Proneness Scale (K-SAPS) for adults, the Behavioral Inhibition System/Behavioral Activation System questionnaire (BIS/BAS), the Dickman Dysfunctional Impulsivity Instrument (DDII), and the Brief Self-Control Scale (BSCS). In addition, participants reported their demographic information and smartphone usage pattern (weekday or weekend average usage hours and main use). We analyzed the data in three steps: (1) identifying predictors with logistic regression, (2) deriving causal relationships between SAP and its predictors using a Bayesian belief network (BN), and (3) computing optimal cut-off points for the identified predictors using the Youden index. Identified predictors of SAP were as follows: gender (female), weekend average usage hours, and scores on BAS-Drive, BAS-Reward Responsiveness, DDII, and BSCS. Female gender and scores on BAS-Drive and BSCS directly increased SAP. BAS-Reward Responsiveness and DDII indirectly increased SAP. We found that SAP was defined with maximal sensitivity as follows: weekend average usage hours > 4.45, BAS-Drive > 10.0, BAS-Reward Responsiveness > 13.8, DDII > 4.5, and BSCS > 37.4. This study raises the possibility that personality factors contribute to SAP. And, we calculated cut-off points for key predictors. These findings may assist clinicians screening for SAP using cut-off points, and further the understanding of SA risk factors. PMID:27533112

  10. Sex differences in impulsive and compulsive behaviors: a focus on drug addiction.

    Science.gov (United States)

    Fattore, Liana; Melis, Miriam

    2016-09-01

    Sex differences in inhibition and self-regulation at a behavioral level have been widely described. From an evolutionary point of view, the different selection pressures placed on male and female hominids led them to differ in their behavioral strategies that allowed our species to survive during natural selection processes. These differences reflect changes in neural and structural plasticity that might be the core of sex differences, and of the susceptibility towards one psychiatric condition rather than another. The goal of the present review is to summarize current evidence for such a dichotomy in impulsive and compulsive behavior with a focus on drug addiction. Sex-dependent differences in drug abuse and dependence will be examined in the context of pathophysiological regulation of impulse and motivation by neuromodulators (i.e. gonadal hormones) and neurotransmitters (i.e. dopamine). Advances in the understanding of the sex differences in the capability to control impulses and motivational states is key for the determination of efficacious biologically based intervention and prevention strategies for several neuropsychiatric disorders where loss of impulse control and compulsivity are the core symptoms.

    A cross-sectional school-based survey study (N=13,284; 53% females; mean age 15.8±0.7) of 14-17-year-old adolescents was conducted in seven European countries (Greece, Spain, Poland, Germany, Romania, the Netherlands, and Iceland). The aim of the study was to investigate the prevalence of Internet addictive behavior (IAB) and related psychosocial characteristics among adolescents in the participating countries. In the study, we distinguish two problematic groups: adolescents with IAB, characterized by a loss of control over their Internet use, and adolescents "at risk for IAB," showing fewer or weaker symptoms of IAB. The two groups combined form a group of adolescents with dysfunctional Internet behavior (DIB). About 1% of adolescents exhibited IAB and an additional 12.7% were at risk for IAB; thus, in total, 13.9% displayed DIB. The prevalence of DIB was significantly higher among boys than among girls (15.2% vs. 12.7%, pInternet, and greater use of social networking sites and gaming sites. Multiple linear regression analysis showed that externalizing (i.e., behavioral) and internalizing (i.e., emotional) problems were associated with the presence of DIB.

Materials and Methods: A cross-sectional study was carried out in women drug treatment centers under the supervision of Welfare Organization of Tehran province in Iran. Data collection process was conducted in three centers including a questionnaire with an interview format, clinical examination, and Chi-Square test and MANOVA for statistical analysis. Results: The mean age of 95 women participating in this study was less than forty, whereas the age of starting drugs was twenty two. A majority of the patients were unemployed (71% and more than that of two-third did not have a diploma education. Almost half of dentate participants had never or rarely brushed their teeth. Most of them had never used dental floss, while more than half had three or more times snacks or sweet drinks and more than three-fourth were daily smokers. The MANOVA analysis showed that the type of clinic to be visited, age, used stimulant, drug dependency length, the last time a dentist being visited and the brushing period had a statistically significant relationship with Decayed Teeth (DT, Missing Teeth (MT and Filled Teeth (FT (P<0.05. Conclusion: Women with the prior drug addiction history had an unpromising oral health status which was obvious in their self-perceived oral health. Taking the appropriate preventive and therapeutic actions aiming for promoting oral health status of them seems to be necessary.

    Many drugs of abuse, including cannabinoids, opioids, alcohol and nicotine, can alter the levels of endocannabinoids in the brain. Recent studies show that release of endocannabinoids in the ventral tegmental area can modulate the reward-related effects of dopamine and might therefore be an important neurobiological mechanism underlying drug addiction. There is strong evidence that the endocannabinoid system is involved in drug-seeking behavior (especially behavior that is reinforced by drug-...

    MacKillop, James

    2013-01-01

    Delayed reward discounting is a behavioral economic index of impulsivity, referring to how much an individual devalues a reward based on its delay in time. As a behavioral process that varies considerably across individuals, delay discounting has been studied extensively as a model for self-control, both in the general population and in clinical…

  18. Attention-Deficit/Hyperactivity Disorder in Relation to Addictive Behaviors: A Moderated-Mediation Analysis of Personality Risk Factors and Sex

    Directory of Open Access Journals (Sweden)

    Caroline eDavis

    2015-04-01

    Full Text Available Introduction: Research has shown that those with ADHD have an increased risk for addiction disorders like alcoholism and substance abuse. What is less clear is the mechanism(s whereby ADHD gives rise to increased engagement in addictive behaviors, and whether there are sex differences in the ADHD-addiction propensity. Both ADHD and addictions have also been associated with personality traits such as impulsivity, reward seeking, anxiousness, and negative affect. In this study, we tested a moderator-mediation model which predicted that both sex and ADHD-symptom status would make independent contributions to the variance in personality risk and in addictive behaviors, with males, and those with diagnosed ADHD, scoring higher on both dependent variables. Our model also predicted that the effect of sex and ADHD-symptom status on addictive behaviors would be via the mediating or intervening influence of personality risk factors. Methods: A community-based sample of young men and women took part in the study. Among these individuals, 46 had received a life-time diagnosis of ADHD. The non-diagnosed participants were dichotomized into a high-ADHD symptom group (n=83 and a low-symptom group (n=84. Results: We found that a high-risk personality profile may, in part, account for the relationship between ADHD symptomatology and the use/abuse of a broad range of addictive behaviors. However,we found no sex differences in personality risk for addiction or in the use of addictive behaviors; nor did sex moderate the relationships we assessed. Conclusions: While ADHD Status showed a strong relationship with both dependent variables in the model, we found no difference between those who had been diagnosed with ADHD and treated with stimulants, and their high-symptom non-diagnosed/non-treated counterparts. These results add support to claims that the treatment of ADHD with stimulant medication neither protects nor fosters the risk for substance abuse disorders.

  20. What is addiction?

    Kranzler, Henry R; Li, Ting-Kai

    2008-01-01

    This issue of Alcohol Research & Health examines addiction to multiple substances--that is, combined dependence on alcohol and other drugs (AODs), including marijuana, cocaine, and opioids. It seems fitting, then, to begin the issue with a look at what constitutes "addiction." The Oxford English Dictionary (pp. 24-25) traces the term addiction to Roman law, under which addiction was a "formal giving over by sentence of court; hence, a dedication of person to a master." This notion of relinquishment of control by the addicted person is the central feature of many lay and professional definitions of the term. The study of addictive behavior crosses several disciplines, including, among others, behavioral neuroscience, epidemiology, genetics, molecular biology, pharmacology, psychology, psychiatry, and sociology. Articles in this issue examine aspects of AOD use disorders from the perspective of some of these varied disciplines. PMID:23584810

    2016-07-01

    Recent data implicate glucagon-like peptide-1 (GLP-1), a potent anorexigenic peptide released in response to nutrient intake, as a regulator for the reinforcing properties of food, alcohol and psychostimulants. While, both central and peripheral mechanisms mediate effects of GLP-1R signaling on food intake, the extent to which central or peripheral GLP-1R signaling regulates reinforcing properties of drugs of abuse is unknown. Here, we examined amphetamine reinforcement, alcohol intake and hedonic feeding following peripheral administration of EX-4 (a GLP-1 analog) in FLOX and GLP-1R KD(Nestin) (GLP-1R selectively ablated from the central nervous system) mice (n=13/group). First, the effect of EX-4 pretreatment on the expression of amphetamine-induced conditioned place preference (Amp-CPP) was examined in the FLOX and GLP-1R KD(Nestin) mice. Next, alcohol intake (10% v/v) was evaluated in FLOX and GLP-1R KD(Nestin) mice following saline or EX-4 injections. Finally, we assessed the effects of EX-4 pretreatment on hedonic feeding behavior. Results indicate that Amp-CPP was completely blocked in the FLOX mice, but not in the GLP-1R KD(Nestin) mice following EX-4 pretreatment. Ex-4 pretreatment selectively blocked alcohol consumption in the FLOX mice, but was ineffective in altering alcohol intake in the GLP-1R KD(Nestin) mice. Notably, hedonic feeding was partially blocked in the GLP-1R KD(Nestin) mice, whereas it was abolished in the FLOX mice. The present study provides critical insights regarding the nature by which GLP-1 signaling controls reinforced behaviors and underscores the importance of both peripheral and central GLP-1R signaling for the regulation of addictive disorders.

    2002-10-01

    The goals of present article are three – fold: In the first step, it introduces a brief form of motivational Interviewing for addictive behaviors. Its primary basis is the idea that most substance abusers seek medical treatment without being ready to change addictive behaviors. As a result, attempts the addicts to change often lead to their resistance. Therefore, the use of motivational interviewing (MI in which clients are directed towards realizing their own reasons and arguments for changing their behavior, seems to be most oppropriate to motivate and prepare them for change. In the second step, the article tries to discuss advantages of motivational interviewing approach to often opproaches (e.g, skills training approach, Indirect approach and confrontational – denial approach and suggests that (MI is the most appropriate strategy for the substance abusers, according to their degree of readiness for change. Finally in the third step, the article attempts to indicate the current dominant strategies of addiction treatment in Iran and concludes that due to dominance and commonality of medicine – based treatment strategies of addictive behaviors, (MI could be introduced as an alternative and appropriate treatment strategy for drug addicts in Iran.

    Background US veterans report lower health-related quality of life (HRQoL) relative to the general population. Identifying behavioral factors related to HRQoL that are malleable to change may inform interventions to improve well-being in this vulnerable group. Purpose The current study sought to characterize HRQoL in a largely male sample of veterans in addictions treatment, both in relation to US norms and in association with five recommended health behavior practices: regularly exercising, managing stress, having good sleep hygiene, consuming fruits and vegetables, and being tobacco free. Methods We assessed HRQoL with 250 veterans in addictions treatment (96 % male, mean age 53, range 24–77) using scales from four validated measures. Data reduction methods identified two principal components reflecting physical and mental HRQoL. Model testing of HRQoL associations with health behaviors adjusted for relevant demographic and treatment-related covariates. Results Compared to US norms, the sample had lower HRQoL scores. Better psychological HRQoL was associated with higher subjective social standing, absence of pain or trauma, lower alcohol severity, and monotonically with the sum of health behaviors (all p management, and sleep hygiene. Regular exercise also related to better physical HRQoL. The models explained >40 % of the variance in HRQoL. Conclusions Exercise, sleep hygiene, and stress management are strongly associated with HRQoL among veterans in addictions treatment. Future research is needed to test the effect of interventions for improving well-being in this high-risk group. PMID:26886926

    Full Text Available Background: addiction and drug abuse have many risk factors in community and individual attitude; also causes much diversity in community perception and attitude toward addiction. Methods: in this study we assessed attitude toward an addict in 42 addict men and asked about problems in their community and recreational behaviors. They were residents of a rural area in Babol city. In the control group we assessed the same parameters in 268 non addicts in the same area. All of the addicts have been using opium more than many times a week at least for recent 6 months. Data collected via a semi structured questionnaire through conversation. Results: There was a significant difference between addicts’ attitude toward toward addiction compare to non-addicts’. Both addicts and non-addicts indicated that the first three community problems in their area were unemployment, lack of recreational facilities and addiction, in respective order. Answering questions about recreational activities, both groups indicated that there were no recreational facilities in the community. Conclusion: In planning a preventive approach, there is a major role for attitude toward addiction in any community. The conflict seen in this study between addicts’ attitudes toward an addicted person and addiction as a community problem has it’s interesting feature. Recreation and physical and cultural facilities need to pay more attention as indicated by our study participants. This seems to have an important impact in prevention of many community problems as well as addiction.

  9. Is Overeating Behavior Similar to Drug Addiction? (427th Brookhaven Lecture)

    International Nuclear Information System (INIS)

    The increasing number of obese individuals in the U.S. and other countries world-wide adds urgency to the need to understand the mechanisms underlying pathological overeating. Research by the speaker and others at Brookhaven National Laboratory and elsewhere is compiling evidence that the brain circuits disrupted in obesity are similar to those involved in drug addiction. Using positron emission tomography (PET), the speaker and his colleagues have implicated brain dopamine in the normal and the pathological intake of food by humans. During the 427th Brookhaven Lecture, speaker will review the findings and implications of PET studies of obese subjects and then compare them to PET research involving drug-addicted individuals. For example, in pathologically obese subjects, it was found that reductions in striatal dopamine D2 receptors are similar to those observed in drug-addicted subjects. The speaker and his colleagues have postulated that decreased levels of dopamine receptors predisposed subjects to search for strongly rewarding reinforcers, be it drugs for the drug-addicted or food for the obese, as a means to compensate for decreased sensitivity of their dopamine-regulated reward circuits. As the speaker will summarize, multiple but similar brain circuits involved in reward, motivation, learning and inhibitory control are disrupted both in drug addiction and obesity, resulting in the need for a multimodal approach to the treatment of obesity.

    As addiction professionals, we are becoming increasingly concerned about preteenagers and young adults' involvement with substance abuse as a way of relieving stress and anger. The turbulent underdeveloped central nervous system, especially in the prefrontal cortex (PFC), provides impetus to not only continue important neuroimaging studies in both human and animal models, but also to encourage preventive measures and cautions embraced by governmental and social media outlets. It is well known that before people reach their 20s, PFC development is undergoing significant changes and, as such, hijacks appropriate decision making in this population. We are further proposing that early genetic testing for addiction risk alleles will offer important information that could potentially be utilized by their parents and caregivers prior to use of psychoactive drugs by these youth. Understandably, family history, parenting styles, and attachment may be modified by various reward genes, including the known bonding substances oxytocin/vasopressin, which effect dopaminergic function. Well-characterized neuroimaging studies continue to reflect region-specific differential responses to drugs and food (including other non-substance-addictive behaviors) via either "surfeit" or "deficit." With this in mind, we hereby propose a "reward deficiency solution system" that combines early genetic risk diagnosis, medical monitoring, and nutrigenomic dopamine agonist modalities to combat this significant global dilemma that is preventing our youth from leading normal productive lives, which will in turn make them happier.

    Little is known about the co-occurrence of health risk behaviors in childhood that may signal later addictive behavior. Using a survey, this study evaluated high calorie, low nutrient HCLN intake and video gaming behaviors in 964 fourth grade children over 18 months, with stress, sensation-seeking, inhibitory control, grades, perceived safety of environment, and demographic variables as predictors. SEM and growth curve analyses supported a co-occurrence model with some support for addiction specificity. Male gender, free/reduced lunch, low perceived safety and low inhibitory control independently predicted both gaming and HCLN intake. Ethnicity and low stress predicted HCLN. The findings raise questions about whether living in some impoverished neighborhoods may contribute to social isolation characterized by staying indoors, and HCLN intake and video gaming as compensatory behaviors. Future prevention programs could include skills training for inhibitory control, combined with changes in the built environment that increase safety, e.g., implementing Safe Routes to School Programs.

  19. Addiction and Will

    Directory of Open Access Journals (Sweden)

    Brian eJohnson

    2013-09-01

    Full Text Available ADDICTION AND WILLA hypothesis about the neurobiological bases of drive, drive reduction and will in addictive illness is presented. Drive reduction seems to require both SEEKING and gratification. Will is the everyday term for our experience of drives functioning within us. Addictive drugs take over the will by altering neurotransmission in the SEEKING system. As a result of this biological change, psychological defenses are arrayed that allow partial gratification and reduce anxiety about the consequences of drug use. Repeated partial gratification of the addictive drive creates a cathexis to the drug and the drug seller. It also keeps the addicted person in a permanent state of SEEKING.The cathexis to the drug and drug seller creates a difficult situation for psychoanalytic therapists. The actively addicted patient will have one set of feelings for the analyst, and a split off set of feelings for the drug dealer. Addictive neuroses, which feature a split transference, are contrasted with Freud’s concept of transference and narcissistic neuroses. For treatment of an actively addicted patient, the treater must negotiate the split transference. By analyzing the denial system the relationship with the drug dealer ends and the hostility involved in addictive behavior enters the transference where it can be interpreted.Selling drugs that take over the will is a lucrative enterprise. The addictive drug industry, about the size of the oil and gas industry worldwide, produces many patients in need of treatment. The marketers of addictive drugs understand the psychology of inducing initial ingestion of the drugs, and of managing their addicted populations. The neuropsychoanalytic understanding of addiction might be used to create more effective public health interventions to combat this morbid and mortal illness.

    Full Text Available AbstractDrug addiction is viewed as a maladaptive memory induced by contextual cues even in the abstinent state. However, the variations of hedonia and appetite induced by the context during the abstinence have been neglected. To distinguish the representative behaviors between hedonia and appetite, micro-behaviors in abstinent animal such as psycho-activity and drug seeking behaviors were observed in morphine conditioned place preference (CPP. To confirm the different effects of reward between drug and natural reward, a palatable food CPP paradigm was compared in current work. After a 10-day training in CPP with morphine or food, the preference was tested on day 1, 14, 28, and the changes of micro-behaviors were analyzed further. Our data showed that tree shrews treated with morphine performed more jumps on day 1 and more visits to saline paired side on day 28, which indicated a featured behavioral transition from psycho-activity to seeking behavior during drug abstinence. Meanwhile, food-conditioned animals only displayed obvious seeking behaviors in the three tests. The results suggest that the variations of micro-behaviors could imply such a transition from hedonic response to appetitive behaviors during morphine abstinence, which provided a potential behavioral basis for further neural mechanism studies.

    Background and Aims Exercise dependence (EXD) is considered a behavioral addiction that is often associated with eating disorders. To date, only few studies examined the potential overlap between EXD and other addictive behaviors. Therefore, the present study aimed at investigating the relationship of EXD with pathological buying, pathological video gaming (offline and online), hypersexual behavior, and alcohol use disorder in a sample of clients of fitness centers. Methods The following questionnaires were answered by 128 individuals (age M = 26.5, SD = 6.7 years; 71.7% men, 74.2% university students): Exercise Dependence Scale, Eating Disorder Examination-Questionnaire, Compulsive Buying Scale, Pathological Computer-Gaming Scale, Hypersexual Behavior Inventory, and Alcohol Use Disorders Identification Test (AUDIT). Results 7.8% of the sample were at-risk for EXD, 10.9% reported eating disorder pathology, 2.3% pathological buying, 3.1% hypersexual behavior, and none of the participants suffered from pathological video gaming. The criteria for severe alcohol disorder pathology (AUDIT ≥ 16) were fulfilled by 10.2%. With regard to continuous symptom scores, EXD symptoms were positively correlated with both eating disorder pathology and pathological buying but not with pathological video gaming, hypersexuality or alcohol use disorder. It is noteworthy that more symptoms of pathological buying corresponded with more symptoms of hypersexual behavior. The correlation pattern did not differ by gender. Discussion The co-occurrence of EXD, pathological buying and hypersexual behavior on a subclinical level or in the early stage of the disorders should be taken into account when assessing and treating patients. More research is warranted in order to investigate possible interactions between these conditions. PMID:26690622

  7. Addiction and will.

    A hypothesis about the neurobiological bases of drive, drive reduction and will in addictive illness is presented. Drive reduction seems to require both SEEKING and gratification. Will is the everyday term for our experience of drives functioning within us. Addictive drugs take over the will by altering neurotransmission in the SEEKING system. As a result of this biological change, psychological defenses are arrayed that allow partial gratification and reduce anxiety about the consequences of drug use. Repeated partial gratification of the addictive drive creates a cathexis to the drug and the drug seller. It also keeps the addicted person in a permanent state of SEEKING. The cathexis to the drug and drug seller creates a difficult situation for psychoanalytic therapists. The actively addicted patient will have one set of feelings for the analyst, and a split off set of feelings for the drug dealer. Addictive neuroses, which feature a split transference, are contrasted with Freud's concept of transference and narcissistic neuroses. For treatment of an actively addicted patient, the treater must negotiate the split transference. By analyzing the denial system the relationship with the drug dealer ends and the hostility involved in addictive behavior enters the transference where it can be interpreted. Selling drugs that take over the will is a lucrative enterprise. The addictive drug industry, about the size of the oil and gas industry worldwide, produces many patients in need of treatment. The marketers of addictive drugs understand the psychology of inducing initial ingestion of the drugs, and of managing their addicted populations. The neuropsychoanalytic understanding of addiction might be used to create more effective public health interventions to combat this morbid and mortal illness. PMID:24062657

Non-invasive brain stimulation, among which transcranial direct current stimulation (tDCS, has opened up new perspectives in addiction treatment. The purpose of this work is to conduct a critical and systematic review of tDCS efficacy, and of technical and methodological considerations in the field of BA.Methods.A bibliographic search has been conducted on the Medline and ScienceDirect databases until December 2014, based on the following selection criteria: clinical studies on tDCS and BA (namely eating disorders, compulsive buying, Internet addiction, pathological gambling, sexual addiction, sports addiction, video games addiction. Study selection, data analysis and reporting were conducted according to the PRISMA guidelines.Results.Out of 402 potential articles, seven studies were selected. So far focusing essentially on abnormal eating, these studies suggest that tDCS (right prefrontal anode / left prefrontal cathode reduces food craving induced by visual stimuli.ConclusionsDespite methodological and technical differences between studies, the results are promising. So far, only few studies of tDCS in BA have been conducted. New research is recommended on the use of tDCS in BA, other than eating disorders.

    2013-09-01

    Appetitive behaviors such as substance use and eating are under significant regulatory control by the hypothalamic-pituitary adrenal (HPA) and hypothalamic pituitary gonadal (HPG) axes. Recent research has begun to examine how these systems interact to cause and maintain poor regulation of these appetitive behaviors. A range of potential molecular, neuroendocrine, and hormonal mechanisms are involved in these interactions and may explain individual differences in both risk and resilience to a range of addictions. This manuscript provides a commentary on research presented during the International Society of Psychoneuroendocrinology's mini-conference on sex differences in eating and addiction with an emphasis on how HPG and HPA axis interactions affect appetitive behaviors in classic addictions and may be used to help inform the ongoing debate about the validity of food addiction.

    Tree shrews represent a suitable animal model to study the pathogenesis of human diseases as they are phylogenetically close to primates and have a well-developed central nervous system that possesses many homologies with primates. Therefore, in our study, we investigated whether tree shrews can be used to explore the addictive behaviors induced by morphine. Firstly, to investigate the psychoactive effect of morphine on tree shrews' behavior, the number of jumping and shuttling, which represent the vertical and horizontal locomotor activity respectively, was examined following the injection of different dosage of morphine. Our results showed intramuscular (IM) injection of morphine (5 or 10 mg/kg) significantly increased the locomotor activity of tree shrews 30-60 min post-injection. Then, using the conditioned place preference/aversion (CPP/CPA) paradigm, we found morphine-conditioned tree shrews exhibited place preference in the morphine-paired chamber on the test day. In addition, naloxone-precipitated withdrawal induced place aversion in the chronic morphine-dependent tree shrews. We evaluated the craving for morphine drinking by assessing the break point that reflects the maximum effort animals will expend to get the drug. Our data showed the break point was significantly increased when compared to the baseline on the 1st, 7th and 14th day after the abstinence. Moreover, in the intravenous morphine self-administration experiment, tree shrews conditioned with morphine responded on the active lever significantly more frequently than on the inactive lever after training. These results suggest that tree shrew may be a potential candidate for study the addictive behaviors and the underling neurological mechanisms.

    Full Text Available Some addictions cannot be connected with substance abuse (pathological gambling, video games playing, binge eating, compulsive physical activity, emotional relationship addiction, TV addiction. Since 1995, Internet addiction has been accepted as a clinical entity with profound negative effect on social, familial, educational and economical personal functioning. The diagnosis of Internet addiction could be established if the person spends more than 38 hours per week on the Internet exempting online professional needs. Basic symptoms are the increased number of hours spent in front of the computer along with the Internet use, development of abstinent syndrome if the Internet access is prohibited, sleep inversion, neglect of basic social requirements and personal hygiene, many somatic symptoms developed due to prolonged sitting or monitor watching, dissocial behavior. In this paper, data about the Internet addiction are presented and a case report of an adolescent with developed Internet addiction.

    Full Text Available Research over the last two decades suggests that a wide range of substance and behavioral addictions may serve similar functions. Yet, co-occurrence of addictions has only been reported among a minority of addicts. “Addiction specificity” pertains to a phenomenon in which one pattern of addictive behaviors may be acquired whereas another is not. This paper presents the PACE model as a framework which might help explain addiction specificity. Pragmatics, attraction, communication, and expectation (PACE variables are described, which may help give some direction to future research needs in this arena.

    Novelty preference or sensation seeking is associated with disorders of addiction and predicts rodent compulsive drug use and adolescent binge drinking in humans. Novelty has also been shown to influence choice in the context of uncertainty and reward processing. Here we introduce a novel or familiar neutral face stimuli and investigate its influence on risk-taking choices in healthy volunteers. We focus on behavioural outcomes and imaging correlates to the prime that might predict risk seeking. We hypothesized that subjects would be more risk seeking following a novel relative to familiar stimulus. We adapted a risk-taking task involving acceptance or rejection of a 50:50 choice of gain or loss that was preceded by a familiar (pre-test familiarization) or novel face prime. Neutral expression faces of males and females were used as primes. Twenty-four subjects were first tested behaviourally and then 18 scanned using a different variant of the same task under functional MRI. We show enhanced risk taking to both gain and loss anticipation following novel relative to familiar images and particularly for the low gain condition. Greater risk taking behaviour and self-reported exploratory behaviours was predicted by greater right ventral putaminal activity to novel versus familiar contexts. Social novelty appears to have a contextually enhancing effect on augmenting risky choices possibly mediated via ventral putaminal dopaminergic activity. Our findings link the observation that novelty preference and sensation seeking are important traits predicting the initiation and maintenance of risky behaviours, including substance and behavioural addictions.

    Full Text Available Background: Drug addiction is one of the social health problems at the present century. The high risk sexual behaviors as well as drug abusing are factors of sexually transmitted infections. This study aimed to determine the prevalence of sexually transmitted infections and high risk behaviors among women who have referred to a de-addiction center. Methods: In this descriptive study, 76 women who have referred to Niloofar de-addiction center in Kermanshah-Western Iran, were recruited using convenience sampling method. Questionnaire was completed by all subjects and blood sample were taken to determine Hepatitis B, Syphilis, and Herpes simplex virus infection. Data were analyzed using descriptive statistics, t- test, Chi-2 and the Fisher exact test. Results: The mean age of women was 35.22±0.99 year. 51.3% of subjects were illiterate and 48.7% were supported by social welfare system. There were not common needle using and multiple sexual contacts in the subjects. None of the subjects had positive test for hepatitis B and syphilis but HSV antibody was determined in 91.6% of subjects.Conclusion: In this study, high-risk behaviors and sexually transmitted diseases were less than expected. This study was carried out in a state governmental clinic, future studies in different populations of addicted women referred to prison and private sectors are recommended.

    Full Text Available Addiction is a primary, chronic, neurobiological disease, with genetic, psychosocial, and environmental factors influencing its development. Developments in the psychopharmacology of addiction is much slower than the other disciplines of psychiatry. For a long time, social and behavioral therapeutic approaches are the only choices for the treatment of addictive disorders. Disulfiram was the only pharmacological agent approved for addiction treatment until the end of 20th century. Pharmacological treatment options available for treatment have grown along with our understanding of the neurobiological mechanisms underlying the development and persistence of addiction. Several new medications like naltrexone, acamprosate, methadone and buprenoprhine have been approved for the treatment of alcohol and opioid use disorders ever since. Based on ever-increasing information about neurotransmitter and receptors, many studies have been performed concerning craving and relapse prevention in recent years. Besides many other pharmacological agents have been focus of new researches for treatment of different types of addiction. The aim of this article is to briefly review the literature on psychopharmacology of addictive disorders and recent developments in this area.

    Previous studies have reported associations between aggression and Internet addiction disorder (IAD), which has also been linked with anxiety, depression, and impulsiveness. However, the causal relationship between aggression and IAD has thus far not been clearly demonstrated. This study was designed to (a) examine the association between aggression and IAD and (b) investigate the mediating effects of anxiety, depression, and impulsivity in cases in which IAD predicts aggression or aggression predicts IAD. A total of 714 middle school students in Seoul, South Korea, were asked to provide demographic information and complete the Young's Internet Addiction Test (Y-IAT), the Buss-Perry Aggression Questionnaire, the Barratt Impulsiveness Scale-11, the State-Trait Anger Expression Inventory-2, the Beck Anxiety Inventory, the Beck Depression Inventory, and the Conners-Wells Adolescent Self-Report Scale. Three groups were identified based on the Y-IAT: the usual user group (n=487, 68.2%), the high-risk group (n=191, 26.8%), and the Internet addiction group (n=13, 1.8%). The data revealed a linear association between aggression and IAD such that one variable could be predicted by the other. According to the path analysis, the clinical scales (BAI, BDI, and CASS) had partial or full mediating effects on the ability of aggression to predict IAD, but the clinical scales had no mediating effect on the ability of IAD to predict aggression. The current findings suggest that adolescents with IAD seem to have more aggressive dispositions than do normal adolescents. If more aggressive individuals are clinically prone to Internet addiction, early psychiatric intervention may contribute to the prevention of IAD. PMID:25902276

    Full Text Available Objective: The aim of this study was the Study of effectiveness of Marlaat’s cognitive behavior intervention and group treatment based on change stages for recovery and relapse rates in male heroin crack addictions. Method: In a experimental research design, 45 men addictions, who were diagnosed as the dependence of the heroin crack on the basis of DSM-IV-TR criteria, were chosen after successfully detoxified. They were divided two experimental groups (30 participants and a control group (15 participants that have been selected by random sampling. The first experimental group was undergone group treatment based on change stages underwent 16 sessions of 1.5 hours, totally 24 hours and the second experimental groups who were undergone Marlaat’s cognitive behavior intervention has been held 15 sessions of 2 hours, totally 24 hours. The control group were just received MMT without any psychotherapy. All participants were assessed by structured interview, urine test, before treatment, after treatment and after 3 months follow up. Results: Results showed that both psychotherapy treatments were affected on recovery and relapse rates. Conclusion: It seems that psychological problems and conflicts before addiction and after addiction could be caused for individuals’ tendency to narcotics consumption. Therefore, applying of psychotherapy could be useful in relapse prevention.

    The aim of this qualitative study was to examine the narratives of people who experience chronic pain (lasting 6 months or more) and were receiving methadone for the treatment of their opiate addiction through a major methadone clinic. This paper featured the pathway of how the participants developed chronic pain and addiction, and their beliefs of how prescription opioids would impact their addiction in the future. Thirty-four participants who experienced chronic pain and received methadone for treatment of opiate addiction were willing to tell the story of their experiences. The findings in three areas are presented: (a) whether participants experienced addiction first or pain first and how their exposures to addictive substances influenced their experiences, (b) the significance of recreational drug use and patterns of abuse behaviors leading to chronic pain, and (c) participants' experiences and beliefs about the potential for abuse of prescription opioid used for treatment of pain.

  10. Interactions between opioids and anabolic androgenic steroids: implications for the development of addictive behavior.

    Nyberg, Fred; Hallberg, Mathias

    2012-01-01

    Over the past decades, research on doping agents, such as anabolic androgenic steroids (AAS), has revealed that these compounds are often used in combination with other drugs of abuse. It seems that misuse of AAS probably involves more than a desire to enhance appearance or sports performance and studies have revealed that steroids are commonly connected with alcohol, opioids, tobacco, and psychotropic drugs. We have observed that AAS may interact with the endogenous opioids, excitatory amino acids, and dopaminergic pathways involved in the brain reward system. Furthermore, our studies provide evidence that AAS may induce an imbalance in these signal systems leading to an increased sensitivity toward opioid narcotics and central stimulants. In fact, studies performed in various clinics have shown that individuals taking AAS are likely to get addicted to opioids like heroin. This chapter reviews current knowledge on interactions between AAS and endogenous as well as exogenous opioids based not only on research in our laboratory but also on research carried out by several other clinical and preclinical investigators.

Participants were assessed with the Chinese version of the adult ADHD Self-report scale (ASRS), the Revised Chen Internet Addiction Scale (CIAS-R), the Barratt Impulsiveness Scale 11 (BIS-11), the Tridimensional Personality Questionnaire (TPQ), the UCLA loneliness scale, and the Behavioral Inhibition System and Behavioral Activation System Scale (BIS/BAS Scale). The results of hierarchical regression analysis indicated that impulsiveness, loneliness, and behavioral inhibition system were significant predictors of Internet addition among adults with ADHD. Higher loneliness was significantly associated with more severe Internet addition symptoms among the non-ADHD group. Adults with high impulsiveness, loneliness, and BIS should be treated with caution for preventing Internet addiction. In addition, adults with and without ADHD should be provided with different preventative strategies. PMID:27449004

    Neurons that produce histamine are exclusively located in the tuberomamillary nucleus of the posterior hypothalamus and send widespread projections to almost all brain areas. Neuronal histamine is involved in many physiological and behavioral functions such as arousal, feeding behavior and learning. Although conflicting data have been published, several studies have also demonstrated a role of histamine in the psychomotor and rewarding effects of addictive drugs. Pharmacological and brain lesion experiments initially led to the proposition that the histaminergic system exerts an inhibitory influence on drug reward processes, opposed to that of the dopaminergic system. The purpose of this review is to summarize the relevant literature on this topic and to discuss whether the inhibitory function of histamine on drug reward is supported by current evidence from published results. Research conducted during the past decade demonstrated that the ability of many antihistaminic drugs to potentiate addiction-related behaviors essentially results from non-specific effects and does not constitute a valid argument in support of an inhibitory function of histamine on reward processes. The reviewed findings also indicate that histamine can either stimulate or inhibit the dopamine mesolimbic system through distinct neuronal mechanisms involving different histamine receptors. Finally, the hypothesis that the histaminergic system plays an inhibitory role on drug reward appears to be essentially supported by place conditioning studies that focused on morphine reward. The present review suggests that the development of drugs capable of activating the histaminergic system may offer promising therapeutic tools for the treatment of opioid dependence.

    Full Text Available Internet addiction is regarded as a growing health concern in many parts of the world with prevalence rates of 1-2% in Europe and up to 7% in some Asian countries. Clinical research has demonstrated that Internet addiction is accompanied with loss of interests, decreased psychosocial functioning, social retreat, and heightened psychosocial distress. Specialized treatment programs are needed to face this problem that has recently been added to the appendix of the DSM-5. While there are numerous studies assessing clinical characteristics of patients with Internet addiction, the knowledge about the effectiveness of treatment programs is limited. Although a recent meta-analysis indicates that those programs show effects, more clinical studies are needed here. To add knowledge, we conducted a pilot study on the effects of a standardized cognitive-behavioral therapy program for IA. 42 male adults meeting criteria for Internet addiction were enrolled. Their IA-status, psychopathological symptoms, and perceived self-efficacy expectancy were assessed before and after the treatment. The results show that 70.3% of the patients finished the therapy regularly. After treatment symptoms of IA had decreased significantly. Psychopathological symptoms were reduced as well as associated psychosocial problems. The results of this pilot study emphasize findings from the only meta-analysis conducted so far.

    The dopamine system is a primary treatment target for cocaine dependence (CD), but research on dopaminergic abnormalities (eg, D2 receptor system deficiencies) has so far failed to translate into effective treatment strategies. The D3 receptor system has recently attracted considerable clinical interest, and D3 antagonism is now under investigation as a novel avenue for addiction treatment. The objective here was to evaluate the status and behavioral relevance of the D3 receptor system in CD, using the positron emission tomography (PET) radiotracer [11C]-(+)-PHNO. Fifteen CD subjects (many actively using, but all abstinent 7–240 days on scan day) and fifteen matched healthy control (HC) subjects completed two PET scans: one with [11C]-(+)-PHNO to assess D3 receptor binding (BPND; calculated regionally using the simplified reference tissue model), and for comparison, a second scan with [11C]raclopride to assess D2/3 binding. CD subjects also completed a behavioral battery to characterize the addiction behavioral phenotype. CD subjects showed higher [11C]-(+)-PHNO BPND than HC in the substantia nigra, which correlated with behavioral impulsiveness and risky decision making. In contrast, [11C]raclopride BPND was lower across the striatum in CD, consistent with previous literature in ⩾2 week abstinence. The data suggest that in contrast to a D2 deficiency, CD individuals may have heightened D3 receptor levels, which could contribute to addiction-relevant traits. D3 upregulation is emerging as a biomarker in preclinical models of addiction, and human PET studies of this receptor system can help guide novel pharmacological strategies for treatment.

    Many recognize that several behaviors potentially affecting the reward circuitry in human brains lead to a loss of control and other symptoms of addiction in at least some individuals. Regarding Internet addiction, neuroscientific research supports the assumption that underlying neural processes are similar to substance addiction. The American Psychiatric Association (APA) has recognized one such Internet related behavior, Internet gaming, as a potential addictive disorder warranting further study, in the 2013 revision of their Diagnostic and Statistical Manual. Other Internet related behaviors, e.g., Internet pornography use, were not covered. Within this review, we give a summary of the concepts proposed underlying addiction and give an overview about neuroscientific studies on Internet addiction and Internet gaming disorder. Moreover, we reviewed available neuroscientific literature on Internet pornography addiction and connect the results to the addiction model. The review leads to the conclusion that Internet pornography addiction fits into the addiction framework and shares similar basic mechanisms with substance addiction. Together with studies on Internet addiction and Internet Gaming Disorder we see strong evidence for considering addictive Internet behaviors as behavioral addiction.

    Exercise in appropriate quantity and of proper quality contributes significantly to the preserve our health. On the contrary, excessive exercise may be harmful to health. The term 'exercise addiction' has been gaining increasing recognition to describe the latter phenomenon. The exact definition of exercise addiction and its potential associations with other disorders is still under study, although according to the authors this phenomenon can be primarily described as a behavioral addiction. Accordingly, exercise addiction, among other behavioral and mental disorders, can be well describe within the obsessive-compulsive spectrum suggested by Hollander (1993). There are several tools used to assess exercise addiction. The authors here present the Hungarian version of the Exercise Dependence Scale (Hausenblas és Downs, 2002) and the Exercise Addiction Inventory (Terry, Szabo és Griffiths, 2004). Exercise addiction has many symptoms in common and also shows a high comorbidity with eating disorders and body image disorders. It may be more closely associated with certain sports but more data is needed to demonstrate this specificity with more certainty. Sel-evaluation problems seem to have a central role in the etiology from a psychological aspect. The relevance of neurohormonal mechanisms is less clear. The authors emphasize the importance of further research on exercise addiction. One important question to be answered is if this disorder is an independent entity to be classified as a distinct clinical disorder or is it rather a subgroup of another disorder.

On the other hand, internet use disorder and internet addiction (IA) have become reportedly serious health and social problems. In 2013, internet gaming disorder criteria have been proposed in the section of Conditions for Further Study of DSM-5. Existing epidemiological studies by questionnaire methods have reported that the prevalence of IA ranges between 2.8% and 9.9% among youths in Japan. Attention deficit hyperactivity disorder (ADHD), sleeping disorders, depression, obsessive compulsive disorder, and phobic anxiety disorder are extremely common comorbid mental disorders with IA. Some psychotherapies (e.g., cognitive behavioral therapy, motivational interviewing) and medical treatments (e.g., antidepressant drugs, methylphenidate) for comorbid mental disorders as well as rehabilitation (e.g., treatment camp) are effective for IA remission. However, some serious cases of IA may be difficult to treat, and prevention is very important. In future, the prevention, rehabilitations and treatments for IA will be more required in Japan.

The reason to addict the internet or smartphone is personalized individual characters related personal psychological and emotional factors and social environmental factors around them. We have shown that 2 discernible approaches due to 2 different addiction causes: that is behavioral treatment and complementary treatment. In the behavioral treatment, cognitive behavioral approach (CBT) is representative methods for changing additive thoughts and behaviors. Motivational interviewing (MI) is also the brief approach for persons not ready to change their behavior. Mindfulness behavioral cognitive treatment (MBCT) also the adapted treatment based on CBT. There are different types following the emphatic point, mindfulness-based relapse prevention (MBRP) or mindfulness oriented recovery enhancement (MORE). It is apparent that therapeutic recreation, music therapy using drumming activity, and art therapy are useful complementary treatment. Exercise rehabilitation contained the systematic procedures and comprehensive activities compared to previous addiction treatments by contents and techniques. Exercise rehabilitation can treat both physical symptoms at first and mental problems in the next step. So more evidence-based exercise rehabilitation researches need to do, but it is highly probable that exercise rehab can apply for smartphone addiction.

    International Nuclear Information System (INIS)

    Objective: To identify the neural mechanisms of impulsivity and the response inhibition deficits of the chronic heroin users using event-related functional MRI (stop-signal task). Methods: Seventeen individuals with heroin dependence and 17 healthy control subjects underwent fMRI scan while executing stop -signal task after anatomical scanning in 3.0 T scanner. The AFNI package was used for fMRI data preprocessing and statistical analysis. Results: The behavioral data showed that the stop signal reaction rime (SSRT) of heroin users was significantly longer than that of the control group. There was no significant difference in activation of the primary motor cortex and supplementary motor area between two groups. Comparing to the control group, heroin users had weaker activation in the right dorsal lateral prefrontal cortex, right inferior prefrontal cortex, and anterior cingulated cortex, but stronger activation in bilateral striatum and amygdala while behavioral inhibition needed. Conclusion: The results suggest that heroin users have significant changes within impulsivity and inhibitory network, where the right prefrontal cortex is considered as main region for inhibition, while the anterior cingulated cortex is associated with error monitoring, and the amygdale controls impulsivity and emotion.

    Addiction is a chronic relapsing disorder characterized by repetitive and compulsive drug-seeking behavior and drug abuse despite negative health or social consequences. Cocaine addiction is a significant worldwide public health problem, which has somatic, psychological, psychiatric, socio-economic and judicial complications. Some of the most frequent complications are cardiovascular effects (acute coronary syndrome, cardiac arrhythmias, increased blood pressure); respiratory effects (fibrosis, interstitial pneumonitis, pulmonary hypertension, alveolar haemorrhage, asthma exacerbation; emphysema), neurological effects (strokes, aneurysms, seizures, headaches); risk for contracting HIV/AIDS, hepatitis B and C, sexual transmitted disease and otolaryngologic effects. Other complications are not discussed here. The vast majority of studies indicate that there are cognitive deficits induced by cocaine addiction. Attention, visual and working memories, executive functioning are affected in cocaine users. Psychiatric complications found in clinical practice are major depressive disorders, cocaine-induced paranoia, cocaine-induced compulsive foraging and panic attacks. PMID:19642439

    The dramatically increasing prevalence of obesity, associated with potentially life-threatening health problems, including cardiovascular diseases and type II diabetes, poses an enormous public health problem. It has been proposed that the obesity epidemic can be explained by the concept of 'food addiction'. In this review we focus on possible similarities between binge eating disorder (BED), which is highly prevalent in the obese population, and drug addiction. Indeed, both behavioral and neural similarities between addiction and BED have been demonstrated. Behavioral similarities are reflected in the overlap in DSM-IV criteria for drug addiction with the (suggested) criteria for BED and by food addiction-like behavior in animals after prolonged intermittent access to palatable food. Neural similarities include the overlap in brain regions involved in food and drug craving. Decreased dopamine D2 receptor availability in the striatum has been found in animal models of binge eating, after cocaine self-administration in animals as well as in drug addiction and obesity in humans. To further explore the neurobiological basis of food addiction, it is essential to have an animal model to test the addictive potential of palatable food. A recently developed animal model for drug addiction involves three behavioral characteristics that are based on the DSM-IV criteria: i) extremely high motivation to obtain the drug, ii) difficulty in limiting drug seeking even in periods of explicit non-availability, iii) continuation of drug-seeking despite negative consequences. Indeed, it has been shown that a subgroup of rats, after prolonged cocaine self-administration, scores positive on these three criteria. If food possesses addictive properties, then food-addicted rats should also meet these criteria while searching for and consuming food. In this review we discuss evidence from literature regarding food addiction-like behavior. We also suggest future experiments that could

    Psychotherapists risk making 2 types of errors with clients who struggle with addictive behaviors: failure to addictive behaviors and failure to effectively addictive behaviors. Given the high prevalence of addictive behaviors in clinical populations, therapists are in a unique position to assist individuals with these problems. It is assumed that therapists possess general diagnostic and treatment skills and yet many do not diagnose or do not treat addictive behaviors. Reasons for making these errors include prohibitive beliefs and limited knowledge about addictive behaviors. We offer specific recommendations to reduce these psychotherapy errors. These include: (a) more deliberate screening and diagnosis of addictive behaviors, (b) increased application of empirically supported addiction treatments, (c) required education and training in addictive behaviors, (d) modification of prohibitive attitudes about addressing addictive behaviors, and (e) increased attention paid to the addictive behaviors by professional psychotherapy organizations.

    2012-01-01

    Internet addiction, defined as a maladaptive use of the Internet, is estimated to occur in 8-13% of college students (Chou, Condron, & Belland, 2005). It has become a serious mental health issue worldwide because addicts are impaired in various behavioral aspects including social interactions and academic performance (Morahan-Martin & Schumacher, 2000; Scherer, 1997; Young, 1998). Some researchers consider Internet addiction as a kind of behavioral addiction. However, there are few experimental studies on the cognitive functions of Internet addicts and limited data are available to compare Internet addicts with other addictive behaviors, such as drug abuse and pathological gambling. In the present study, we examined internet addicts' function of decision making. Two groups of participants, 42 Internet addicts (18~22 years old, 32 male, M = 19.79, SD = 1.14) and 42 controls (18~22 years old, 26 male, M = 19.71, SD = 1.13), were compared on the cognitive function and impulsivity by using a Chinese computerized versions of the IGT and Sensation Seeking Scale (SSS). In the IGT, subjects had to choose between four decks of cards. Unknown to the subjects, two piles offered larger short-term gains that are offset by greater risks of heavy losses, and hence were disadvantageous in the long run. The other two piles offered smaller short-term gains and a lower risk of loss that result in long-term maximization of the monetary payoff. The results of the present study showed that (1) compared with controls, sensation seeking of internet addicts was higher significantly, and internet addicts showed significantly higher scores on subscales of thrill and adventure seeking, disinhibition and boredom susceptibility, and they selected significantly less net decks in the Iowa Gambling Task. Furthermore, Internet addicts made no progress in selecting strategy along with the time course of the decision making. (2) reaction patterns for pure win-cards were consistent between

    Hypersexual Disorder has been proposed as a new psychiatric disorder for DSM-V, characterized by an increased frequency and intensity of sexually motivated fantasies, arousal, urges, and enacted behavior in association with an impulsivity component. Excessive appetitive and consummatory behaviors, including hypersexuality, can become a non-chemical addiction. Sexual addiction afflicts people having paraphilic or nonparaphilic behaviors associated with progressive risk-taking sexual behaviors, escalation or progression of sexual behaviors (tolerance), loss of control and significant adverse psychosocial consequences, such as unplanned pregnancy, pair-bond dysfunction, marital separation, financial problems and sexually transmitted diseases including HIV. The most common behaviors involved in sexual addiction are fantasy sex, compulsive masturbation, pornography, cybersex, voyeuristic sex, anonymous sex and multiple sexual partners. These behaviors are intended to reduce anxiety and other dysphoric affects (e.g., shame and depression). Axis I psychiatric diagnosis, especially mood disorders, psychoactive substance abuse disorders and attention deficit hyperactivity disorders, are common comorbid disorders with sexual addiction. There are significant gaps in the current scientific knowledge base regarding the clinical course, development risk factors and family history and data on women with sexual addiction are lacking.

    Kuss, Daria J

    2013-01-01

    In the 2000s, online games became popular, while studies of Internet gaming addiction emerged, outlining the negative consequences of excessive gaming, its prevalence, and associated risk factors. The establishment of specialized treatment centers in South-East Asia, the US, and Europe reflects the growing need for professional help. It is argued that only by understanding the appeal of Internet gaming, its context, and neurobiologic correlates can the phenomenon of Internet gaming addiction be understood comprehensively. The aim of this review is to provide an insight into current perspectives on Internet gaming addiction using a holistic approach, taking into consideration the mass appeal of online games, the context of Internet gaming addiction, and associated neuroimaging findings, as well as the current diagnostic framework adopted by the American Psychiatric Association. The cited research indicates that the individual’s context is a significant factor that marks the dividing line between excessive gaming and gaming addiction, and the game context can gain particular importance for players, depending on their life situation and gaming preferences. Moreover, the cultural context is significant because it embeds the gamer in a community with shared beliefs and practices, endowing their gaming with particular meaning. The cited neuroimaging studies indicate that Internet gaming addiction shares similarities with other addictions, including substance dependence, at the molecular, neurocircuitry, and behavioral levels. The findings provide support for the current perspective of understanding Internet gaming addiction from a disease framework. The benefits of an Internet gaming addiction diagnosis include reliability across research, destigmatization of individuals, development of efficacious treatments, and the creation of an incentive for public health care and insurance providers. The holistic approach adopted here not only highlights empirical research that

    This study provides a demonstration in the rat of a clear genetic difference in the propensity for addiction-related behaviors following prolonged cocaine self-administration. It relies on the use of selectively bred high-responder (bHR) and low-responder (bLR) rat lines that differ in several characteristics associated with "temperament," including novelty-induced locomotion and impulsivity. We show that bHR rats exhibit behaviors reminiscent of human addiction, including persistent cocaine-seeking and increased reinstatement of cocaine seeking. To uncover potential underlying mechanisms of this differential vulnerability, we focused on the core of the nucleus accumbens and examined expression and epigenetic regulation of two transcripts previously implicated in bHR/bLR differences: fibroblast growth factor (FGF2) and the dopamine D2 receptor (D2). Relative to bHRs, bLRs had lower FGF2 mRNA levels and increased association of a repressive mark on histones (H3K9me3) at the FGF2 promoter. These differences were apparent under basal conditions and persisted even following prolonged cocaine self-administration. In contrast, bHRs had lower D2 mRNA under basal conditions, with greater association of H3K9me3 at the D2 promoter and these differences were no longer apparent following prolonged cocaine self-administration. Correlational analyses indicate that the association of H3K9me3 at D2 may be a critical substrate underlying the propensity to relapse. These findings suggest that low D2 mRNA levels in the nucleus accumbens core, likely mediated via epigenetic modifications, may render individuals more susceptible to cocaine addiction. In contrast, low FGF2 levels, which appear immutable even following prolonged cocaine exposure, may serve as a protective factor. PMID:27114539

    Addiction to illicit drugs in one of today's most important social issues. Most addictive drugs lead to irreversible parenchymal changes in the human brain. Neuroimaging data bring to light the pharmacodynamics and pharmacokinetics of the abused drugs, and demonstrate that addiction is a disease of the brain. Continuous researches better illustrate the neurochemical alterations in brain function, and attempt to discover the links to consequent behavioral changes. Newer hypotheses and theories follow the numerous results, and more rational methods of approaching therapy are being developed. Substance abuse is on the rise in Korea, and social interest in the matter as well. On the other hand, diagnosis and treatment of drug addiction is still very difficult, because how the abused substance acts in the brain, or how it leads to behavioral problems in not widely known. Therefore, understanding the mechanism of drug addiction can improve the process of diagnosing addict patients, planning therapy, and predicting the prognosis . Neuroimaging approaches by nuclear medicine methods are expected to objectively judge behavioral and neurochemical changes, and response to treatment. In addition, as genes associated with addictive behavior are discovered, functional nuclear medicine images will aid in the assessment of individuals. Reviewing published literature on neuroimaging regarding nuclear medicine is expected to be of assistance to the management of drug addict patients. What's more, means of applying nuclear medicine to the care of drug addict patients should be investigated further.

  5. Transcriptional Mechanisms of Drug Addiction

    Science.gov (United States)

    2012-01-01

    Regulation of gene expression is considered a plausible mechanism of drug addiction given the stability of behavioral abnormalities that define an addicted state. Numerous transcription factors, proteins that bind to regulatory regions of specific genes and thereby control levels of their expression, have been implicated in the addiction process over the past decade or two. Here we review the growing evidence for the role played by several prominent transcription factors, including a Fos family protein (ΔFosB), cAMP response element binding protein (CREB), and nuclear factor kappa B (NFκB), among several others, in drug addiction. As will be seen, each factor displays very different regulation by drugs of abuse within the brain's reward circuitry, and in turn mediates distinct aspects of the addiction phenotype. Current efforts are geared toward understanding the range of target genes through which these transcription factors produce their functional effects and the underlying molecular mechanisms involved. This work promises to reveal fundamentally new insight into the molecular basis of addiction, which will contribute to improved diagnostic tests and therapeutics for addictive disorders.

    Socially valorised, sport like other forms of behaviour, can take on an addictive aspect. A review of the English and French literatures from 1979 to 2012 was conducted, using PubMed, Google Scholar, EMBASE, and PsycInfo, using the following key words alone or combined :sport, dependence, exercise, addiction. Exercise dependence is defined as a craving for physical activity that leads to extreme exercise intensity and generates physiological and psychological symptoms. Measurement scales have been proposed to make the diagnosis. No epidemiological studies have examined the prevalence of exercise dependence in the general population, although some studies suggest a frequency ranging from 10 to 80%. Disorders begin with a search for pleasure in physical effort, which then gives way to an obsession for sport resulting in a need to practice a sport more and more frequently and intensely. This addiction is more common among alcohol and illicit drug addicts than among the general population, while the rate of eating disorders can reach 40%. Personality traits most often associated are perfectionism, extraversion, and sensation seeking, while possible links between sporting activity and intensive doping will be discussed.

    This article examines the nature of exercise addiction. It presents a broad, congruent and discerning narrative literature review with the aim of providing a deeper understanding of the condition 'exercise addiction', including symptoms and options for treatment. In addition, guidelines are provided with respect to 'healthy' levels of exercise. Criteria used for determining the eligibility of studies evaluated in the review included the provision of relevant information in studies identified using pertinent search terms. The review highlights some of the key distinctions between healthy levels of exercise and exercise addiction. The findings suggest that an individual who is addicted to exercise will continue exercising regardless of physical injury, personal inconvenience or disruption to other areas of life including marital strain, interference with work and lack of time for other activities. 'Addicted' exercisers are more likely to exercise for intrinsic rewards and experience disturbing deprivation sensations when unable to exercise. In contrast, 'committed' exercisers engage in physical activity for extrinsic rewards and do not suffer severe withdrawal symptoms when they cannot exercise. Exercisers must acquire a sense of life-balance while embracing an attitude conducive to sustainable long-term physical, psychological and social health outcomes. Implementation of recommendations by the Canadian Society for Exercise Physiology, which states that all apparently healthy adults between 18 and 64 years of age should accumulate at least 150 minutes of moderate (5 or 6 on a scale of 0-10) to vigorous (7 or 8 on a scale of 0-10) intensity aerobic physical activity per week in bouts of 10 minutes or more, also expressed as 30 minutes per day distributed over 5 days per week, would be a good start.

    The purpose of the current study was to evaluate possible overlapping substance abuse and internet addiction in a large, uniformly sampled population, ranging in age from 13 to 18 years. Participants (N=73,238) in the current study were drawn from the 6th Korea Youth Risk Behavior Web-based Survey (KYRBWS-V) for students from 400 middle schools and 400 high schools in 16 cities within South Korea. Of adolescent internet users, 85.2% were general users (GU), 11.9% were users with potential risk for internet addiction (PR), and 3.0% were users with high risk for internet addiction (HR). There was a difference in the number of students with alcohol drinking among the GU, PR, and HR groups (20.8% vs 23.1% vs 27.4%). There was a difference in the number of students who smoked among the GS, PR, and HR groups (11.7% vs 13.5% vs 20.4%). There was a difference in the number of students with drug use among the GU, PR, and HR groups (1.7% vs 2.0% vs 6.5%). After adjusting for sex, age, stress, depressed mood, and suicidal ideation, smoking may predict a high risk for internet addiction (OR=1.203, p=0.004).

    Individual differences are a hallmark of drug addiction. Here, we describe a rat model based on differential initial responsiveness to low dose cocaine. Despite similar brain cocaine levels, individual outbred Sprague-Dawley rats exhibit markedly different magnitudes of acute cocaine-induced locomotor activity and, thereby, can be classified as low or high cocaine responders (LCRs or HCRs). LCRs and HCRs differ in drug-induced, but not novelty-associated, hyperactivity. LCRs have higher basal numbers of striatal dopamine transporters (DATs) than HCRs and exhibit marginal cocaine inhibition of in vivo DAT activity and cocaine-induced increases in extracellular DA. Importantly, lower initial cocaine response predicts greater locomotor sensitization, conditioned place preference and greater motivation to self-administer cocaine following low dose acquisition. Further, outbred Long-Evans rats classified as LCRs, versus HCRs, are more sensitive to cocaine’s discriminative stimulus effects. Overall, results to date with the LCR/HCR model underscore the contribution of striatal DATs to individual differences in initial cocaine responsiveness and the value of assessing the influence of initial drug response on subsequent expression of addiction-like behaviors.

    The Internet Process Addiction Test (IPAT) was created to screen for potential addictive behaviors that could be facilitated by the internet. The IPAT was created with the mindset that the term "Internet addiction" is structurally problematic, as the Internet is simply the medium that one uses to access various addictive processes. The role of the internet in facilitating addictions, however, cannot be minimized. A new screening tool that effectively directed researchers and clinicians to the specific processes facilitated by the internet would therefore be useful. This study shows that the Internet Process Addiction Test (IPAT) demonstrates good validity and reliability. Four addictive processes were effectively screened for with the IPAT: Online video game playing, online social networking, online sexual activity, and web surfing. Implications for further research and limitations of the study are discussed. PMID:26226007

    There have been several diagnostic labels for persistent, excessive sexual behaviors, often referred in the popular media as sex addiction. Two related diagnoses, Internet addictive disorder and hypersexual disorder, were considered for, but not included in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders. However, most clinicians, even those trained in sexual disorders or addiction medicine, have little to no training in treating sexual compulsivity and cybersex addiction. The authors present the historical context, proposed diagnostic criteria, evaluation protocols, comorbid disorders, speculations about the neuroscience, and treatment recommendations.

    Our understanding of the neuronal and molecular basis of alcohol addiction is still not satisfactory. As a consequence we still miss successful therapy of alcoholism. One of the reasons for such state is the lack of appropriate animal models which would allow in-depth analysis of biological basis of addiction. Here we will present our efforts to create the animal model of alcohol addiction in the automated learning device, the IntelliCage setup. Applying this model to optogenetically modified mice with remotely controlled regulation of selected neuronal populations by light may lead to very precise identification of neuronal circuits involved in coding addiction-related behaviors.

    Full Text Available Daria J KussPsychology Research and Behavior Management, Birmingham City University, Birmingham, UKAbstract: In the 2000s, online games became popular, while studies of Internet gaming addiction emerged, outlining the negative consequences of excessive gaming, its prevalence, and associated risk factors. The establishment of specialized treatment centers in South-East Asia, the US, and Europe reflects the growing need for professional help. It is argued that only by understanding the appeal of Internet gaming, its context, and neurobiologic correlates can the phenomenon of Internet gaming addiction be understood comprehensively. The aim of this review is to provide an insight into current perspectives on Internet gaming addiction using a holistic approach, taking into consideration the mass appeal of online games, the context of Internet gaming addiction, and associated neuroimaging findings, as well as the current diagnostic framework adopted by the American Psychiatric Association. The cited research indicates that the individual's context is a significant factor that marks the dividing line between excessive gaming and gaming addiction, and the game context can gain particular importance for players, depending on their life situation and gaming preferences. Moreover, the cultural context is significant because it embeds the gamer in a community with shared beliefs and practices, endowing their gaming with particular meaning. The cited neuroimaging studies indicate that Internet gaming addiction shares similarities with other addictions, including substance dependence, at the molecular, neurocircuitry, and behavioral levels. The findings provide support for the current perspective of understanding Internet gaming addiction from a disease framework. The benefits of an Internet gaming addiction diagnosis include reliability across research, destigmatization of individuals, development of efficacious treatments, and the creation of an incentive

    Drug addiction involves potentially life-long behavioral abnormalities that are caused in vulnerable individuals by repeated exposure to a drug of abuse. The persistence of these behavioral changes suggests that long-lasting changes in gene expression, within particular regions of the brain, may contribute importantly to the addiction phenotype. Work over the past decade has demonstrated a crucial role for epigenetic mechanisms in driving lasting changes in gene expression in diverse tissues, including brain. This has prompted recent research aimed at characterizing the influence of epigenetic regulatory events in mediating the lasting effects of drugs of abuse on the brain in animal models of drug addiction. This review provides a progress report of this still early work in the field. As will be seen, there is robust evidence that repeated exposure to drugs of abuse induces changes within the brain's reward regions in three major modes of epigenetic regulation-histone modifications such as acetylation and methylation, DNA methylation, and non-coding RNAs. In several instances, it has been possible to demonstrate directly the contribution of such epigenetic changes to addiction-related behavioral abnormalities. Studies of epigenetic mechanisms of addiction are also providing an unprecedented view of the range of genes and non-genic regions that are affected by repeated drug exposure and the precise molecular basis of that regulation. Work is now needed to validate key aspects of this work in human addiction and evaluate the possibility of mining this information to develop new diagnostic tests and more effective treatments for addiction syndromes.

    Intense craving is a core feature of addictive disorder, and cue-induced craving is believed to be a key factor in the maintenance and relapse of addictive behaviors. With the rapid development of the Internet, Internet addiction has become a widespread behavioral problem accompanied by many negative effects. This study used the cue-reactivity paradigm to examine cue-induced craving for the Internet among Internet addicts and non-addicts. Participants were exposed to Internet-related words, and asked to report their craving for the Internet. Results indicated that Internet-related words aroused cue-induced craving for the Internet among both Internet addicts and non-addicts; however, the craving was more intense among Internet addicts. These results suggest that craving may not be a unipolar, all or none state found only in addicts, but may also be present among non-addicts. They indicate that Internet-related words may be able to induce craving for the Internet, and that Internet addiction and other addictions may share similar underlying mechanisms. This finding has important implications for designing interventions for Internet addiction. PMID:27305097

    Among the human population, 15% of drug users develop a pathological drug addiction. This figure increases substantially with nicotine, whereby more than 30% of those who try smoking develop a nicotine addiction. Drug addiction is characterized by compulsive drug-seeking and drug-taking behaviors (craving), and loss of control over intake despite impairment in health, social, and occupational functions. This behavior can be accurately modeled in the rat using an intravenous self-administration (IVSA) paradigm. Initial attempts at establishing nicotine self-administration had been problematic, yet in recent times increasingly reliable models of nicotine self-administration have been developed. The present article reviews different characteristics of the nicotine IVSA model that has been developed to examine nicotine reinforcing and motivational properties in rats. PMID:22231818

    Drug addiction is a chronic relapsing disorder for which research has been dedicated to understand the various factors that contribute to development, loss of control, and persistence of compulsive addictive behaviors. In this review, we provide a broad overview of various theories of addiction, drugs of abuse, and the neurobiology involved across the addiction cycle. Specific focus is devoted to the role of the mesolimbic pathway in acute drug reinforcement and occasional drug use, the mesocortical pathway and associated areas (e.g., the dorsal striatum) in escalation/dependence, and the involvement of these pathways and associated circuits in mediating conditioned responses, drug craving, and loss of behavioral control thought to underlie withdrawal and relapse. With a better understanding of the neurobiological factors that underlie drug addiction, continued preclinical and clinical research will aid in the development of novel therapeutic interventions that can serve as effective long-term treatment strategies for drug-dependent individuals.

    Married men labeled as sexual addicts seek help after being discovered to have had broken monogamy rules for sexual behavior through their use of masturbation, pornography, cybersex, commercial sex involvement, paraphilic pursuits, or affairs. This study analyzed the sexual patterns and dynamics of 30 men who presented to 1 clinician between 2005 and 2009. Their important differences were captured by a 6-category spectrum: (a) no sexual excess beyond breaking the spouse's restrictive rules (n = 2), (b) discovery of husband's longstanding sexual secrets (n = 5), (c) new discovery of the joys of commercial sex (n = 4), (d) the bizarre or paraphilic (n = 7), (e) alternate concept of normal masculinity (n = 5), and (f) spiraling psychological deterioration (n = 7). Only the men with a spiraling psychological deterioration-about 25% of the sample with sexual issues-could reasonably be described as having a sexual addiction. This group experienced significant psychological failures before the onset of their deterioration. Another 25% were adequately defined as paraphilic. Half of the sample was not adequately described using addiction, compulsivity, impulsivity, and relationship incapacity models. The authors discuss the implications of these findings for DSM-5 and treatment. PMID:20432125

    Research into frequent, excessive, and compulsive social network activity has increased the last years, in which terms such as "social network site addiction" and "Facebook addiction" have been used interchangeably. The aim of this review is to offer more knowledge and better understanding of social network site addiction (SNS-addiction) among researchers as well as clinicians by presenting a narrative overview of the research field in terms of definition, measurement, antecedents, consequences, and treatment as well as recommendations for future research efforts. Seven different measures of SNS-addiction have been developed, although they have to a very little extent been validated against each other. The small number of studies conducted so far on this topic suggests that SNS-addiction is associated with health-related, academic, and interpersonal problems/issues. However such studies have relied on a simple cross-sectional study design. It is therefore hard to draw any conclusions about potential causality and long-term effects at this point, beyond hypothetical speculations. Empirical studies suggest that SNS-addiction is caused by dispositional factors (e.g., personality, needs, self-esteem), although relevant explanatory socio-cultural and behavioral reinforcement factors remain to be empirically explored. No well-documented treatment for SNS-addiction exists, but knowledge gained from Internet addiction treatment approaches might be transferable to SNS-addiction. Overall, the research on this topic is in its infancy, and as such the SNS-addiction construct needs further conceptual and empirical exploration. There is a great demand for studies using careful longitudinal designs and studies which include objective measures of both behavior and health based on broad representative samples. PMID:24001298

    Because addictive behaviors typically result from violated homeostasis of the impulsive (amygdala-striatal) and inhibitory (prefrontal cortex) brain systems, this study examined whether these systems sub-serve a specific case of technology-related addiction, namely Facebook "addiction." Using a go/no-go paradigm in functional MRI settings, the study examined how these brain systems in 20 Facebook users (M age = 20.3 yr., SD = 1.3, range = 18-23) who completed a Facebook addiction questionnaire, responded to Facebook and less potent (traffic sign) stimuli. The findings indicated that at least at the examined levels of addiction-like symptoms, technology-related "addictions" share some neural features with substance and gambling addictions, but more importantly they also differ from such addictions in their brain etiology and possibly pathogenesis, as related to abnormal functioning of the inhibitory-control brain system.

    2008-02-01

    Malfunctioning of the brain's reward center is increasingly understood to underlie all addictive behavior. Composed of mesolimbic incentive salience circuitry, the reward center governs all behavior in which motivation has a central role, including acquiring food, nurturing young, and having sex. To the detriment of normal functioning, basic survival activities can pale in importance when challenged by the allure of addictive substances or behaviors. Dopamine is the neurotransmitter driving both normal and addictive behavior. Other neurotransmitters modulate the amount of dopamine released in response to a stimulus, with the salience determined by the intensity of the dopamine pulse. Opiates (either endogenous or exogenous) exemplify such modulators. Prescribed for treating alcoholism, naltrexone blocks opiates' capacity to augment dopamine release. This article reviews naltrexone's mechanism of action in the reward center and describes a novel use for naltrexone in suppressing a euphorically compulsive and interpersonally devastating addiction to Internet pornography.

    2013-12-01

    DESPITE THE IMPORTANCE OF NUMEROUS PSYCHOSOCIAL FACTORS, AT ITS CORE, DRUG ADDICTION INVOLVES A BIOLOGICAL PROCESS: the ability of repeated exposure to a drug of abuse to induce changes in a vulnerable brain that drive the compulsive seeking and taking of drugs, and loss of control over drug use, that define a state of addiction. Here, we review the types of molecular and cellular adaptations that occur in specific brain regions to mediate addiction-associated behavioral abnormalities. These include alterations in gene expression achieved in part via epigenetic mechanisms, plasticity in the neurophysiological functioning of neurons and synapses, and associated plasticity in neuronal and synaptic morphology mediated in part by altered neurotrophic factor signaling. Each of these types of drug-induced modifications can be viewed as a form of "cellular or molecular memory." Moreover, it is striking that most addiction-related forms of plasticity are very similar to the types of plasticity that have been associated with more classic forms of "behavioral memory," perhaps reflecting the finite repertoire of adaptive mechanisms available to neurons when faced with environmental challenges. Finally, addiction-related molecular and cellular adaptations involve most of the same brain regions that mediate more classic forms of memory, consistent with the view that abnormal memories are important drivers of addiction syndromes. The goal of these studies which aim to explicate the molecular and cellular basis of drug addiction is to eventually develop biologically based diagnostic tests, as well as more effective treatments for addiction disorders.

    Science.gov (United States)

    Flanagan, Owen

    2013-01-01

    Addiction is a person-level phenomenon that involves twin normative failures. A failure of normal rational effective agency or self-control with respect to the substance; and shame at both this failure, and the failure to live up to the standards for a good life that the addict himself acknowledges and aspires to. Feeling shame for addiction is not a mistake. It is part of the shape of addiction, part of the normal phenomenology of addiction, and often a source of motivation for the addict to heal. Like other recent attempts in the addiction literature to return normative concepts such as “choice” and “responsibility” to their rightful place in understanding and treating addiction, the twin normative failure model is fully compatible with investigation of genetic and neuroscientific causes of addiction. Furthermore, the model does not re-moralize addiction. There can be shame without blame. PMID:24115936

    Li, Xuan; Wolf, Marina E.

    2014-01-01

    Brain-derived neurotrophic factor (BDNF) has been found to play roles in many types of plasticity including drug addiction. Here we focus on rodent studies over the past two decades that have demonstrated diverse roles of BDNF in models of cocaine addiction. First, we will provide an overview of studies showing that cocaine exposure alters (and generally increases) BDNF levels in reward-related regions including the ventral tegmental area, nucleus accumbens, prefrontal cortex, and amygdala. Then we will review evidence that BDNF contributes to behavioral changes in animal models of cocaine addiction, focusing on conditioned place preference, behavioral sensitization, maintenance and reinstatement of self-administration, and incubation of cocaine craving. Last, we will review the role of BDNF in synaptic plasticity, particularly as it relates to plasticity of AMPA receptor transmission after cocaine exposure. We conclude that BDNF regulates cocaine-induced behaviors in a highly complex manner that varies depending on the brain region (and even among different cell types within the same brain region), the nature of cocaine exposure, and the “addiction phase” examined (e.g., acquisition vs maintenance; early vs late withdrawal). These complexities make BDNF a daunting therapeutic target for treating cocaine addiction. However, recent clinical evidence suggests that the serum BDNF level may serve as a biomarker in cocaine addicts to predict future relapse, providing an alternative direction for exploring BDNF’s potential relevance to treating cocaine addiction.

    Full Text Available Efforts to improve the health of the population are now focused on promoting healthy lifestyle, improve living conditions and to reduce mortality. Health education activities include regular physical activity, optimal nutrition, reduce addictions and stress. The purpose of the survey conducted among 672 first-year female students at the University of Warmia and Mazury in Olsztyn (Poland was to determine the attitudes of young women towards a healthy lifestyle. Using anonymous survey questionnaire asked students about the form of physical activity, nutrition, the presence of stressful situations, the use of drugs, such as alcohol and cigarettes, and the interest in deepening knowledge of public health. The majority of students have participated only in obligatory physical education classes in high school and college. They considered that physical activity during the studies should be voluntary. Only 4.24% of students were total abstinence from alcohol, but 79.10% was non-smoking. Many of the women declared the need to change the diet, reducing alcohol intake and give up smoking habit. The students felt that stress connected with attending university is unavoidable, and thus revealed an interest in reducing and limiting mental tension. Despite their young age, students expressed interest in topics such as: first aid course, nutrition, sexuality, and pregnancy problems.

    Sexual addiction, which is also known as hypersexual disorder, has largely been ignored by psychiatrists, even though the condition causes serious psychosocial problems for many people. A lack of empirical evidence on sexual addiction is the result of the disease's complete absence from versions of the Diagnostic and Statistical Manual of Mental Disorders. However, people who were categorized as having a compulsive, impulsive, addictive sexual disorder or a hypersexual disorder reported having obsessive thoughts and behaviors as well as sexual fantasies. Existing prevalence rates of sexual addiction-related disorders range from 3% to 6%. Sexual addiction/ hypersexual disorder is used as an umbrella construct to encompass various types of problematic behaviors, including excessive masturbation, cybersex, pornography use, sexual behavior with consenting adults, telephone sex, strip club visitation, and other behaviors. The adverse consequences of sexual addiction are similar to the consequences of other addictive disorders. Addictive, somatic and psychiatric disorders coexist with sexual addiction. In recent years, research on sexual addiction has proliferated, and screening instruments have increasingly been developed to diagnose or quantify sexual addiction disorders. In our systematic review of the existing measures, 22 questionnaires were identified. As with other behavioral addictions, the appropriate treatment of sexual addiction should combine pharmacological and psychological approaches. Psychiatric and somatic comorbidities that frequently occur with sexual addiction should be integrated into the therapeutic process. Group-based treatments should also be attempted. PMID:24001295

    Full Text Available Food addiction is a new topic of focus in the scientific literature. Food intake might be concerned as food addiction in some cases, especially in obese cases and over-eaters. Addiction like behaviours are commonly observed mong these people. Recent animal, epidemiological, clinical and genetic studies partly shows the clinical validity of food addiction while the neurobiological studies focused on the similarity between the reward systems present in obesity and drug addiction. However some studies still emphasizes the differences between two. The aim of this article was to review clinical and biological aspects of etiological perspectives of food addiction via available clinical, preclinical and genetic studies.

  11. Rats that binge eat fat-rich food do not show somatic signs or anxiety associated with opiate-like withdrawal: implications for nutrient-specific food addiction behaviors.

    Previous studies suggest that binge eating sugar leads to behavioral and neurochemical changes similar to those seen with drug addiction, including signs of opiate-like withdrawal. Studies are emerging that show multiple neurochemical and behavioral indices of addiction when animals overeat a fat-rich diet. The goal of the present study was to utilize liquid and solid diets high in sugar and fat content to determine whether opiate-like withdrawal is seen after binge consumption of these diets in Sprague-Dawley rats. Control groups were given ad libitum access to the sweet-fat food or standard chow. All rats were then given a battery of tests to measure signs of opiate-like withdrawal, which included somatic signs of distress, elevated plus-maze anxiety, and locomotor hypoactivity. Neither naloxone-precipitated (3 mg/kg) nor deprivation-induced withdrawal was observed in rats that were maintained on a nutritionally complete pelleted sweet-fat diet or a sweet, high-fat diet supplemented with standard rodent chow. Naloxone-precipitated withdrawal was also not seen in rats fed a liquid sweet-fat food. Further, body weight reduction to 85%, which is known to potentiate the reinforcing effects of substances of abuse, did not affect naloxone-precipitated signs of opiate-like withdrawal. Thus, unlike previous findings reported regarding rats with binge access to a sucrose solution, rats that binge eat sweet-fat combinations do not show signs of opiate-like withdrawal under the conditions tested. These data support the idea that excessive consumption of different nutrients can induce behaviors associated with addiction in different ways, and that the behaviors that could characterize "food addiction" may be subtyped based on the nutritional composition of the food consumed.

  12. Striatal Signal Transduction and Drug Addiction

    Philibin, Scott D.; Hernandez, Adan; Self, David W.; Bibb, James A.

    2011-01-01

    Drug addiction is a severe neuropsychiatric disorder characterized by loss of control over motivated behavior. The need for effective treatments mandates a greater understanding of the causes and identification of new therapeutic targets for drug development. Drugs of abuse subjugate normal reward-related behavior to uncontrollable drug-seeking and -taking. Contributions of brain reward circuitry are being mapped with increasing precision. The role of synaptic plasticity in addiction and underlying molecular mechanisms contributing to the formation of the addicted state are being delineated. Thus we may now consider the role of striatal signal transduction in addiction from a more integrative neurobiological perspective. Drugs of abuse alter dopaminergic and glutamatergic neurotransmission in medium spiny neurons of the striatum. Dopamine receptors important for reward serve as principle targets of drugs abuse, which interact with glutamate receptor signaling critical for reward learning. Complex networks of intracellular signal transduction mechanisms underlying these receptors are strongly stimulated by addictive drugs. Through these mechanisms, repeated drug exposure alters functional and structural neuroplasticity, resulting in transition to the addicted biological state and behavioral outcomes that typify addiction. Ca2+ and cAMP represent key second messengers that initiate signaling cascades, which regulate synaptic strength and neuronal excitability. Protein phosphorylation and dephosphorylation are fundamental mechanisms underlying synaptic plasticity that are dysregulated by drugs of abuse. Increased understanding of the regulatory mechanisms by which protein kinases and phosphatases exert their effects during normal reward learning and the addiction process may lead to novel targets and pharmacotherapeutics with increased efficacy in promoting abstinence and decreased side effects, such as interference with natural reward, for drug addiction.

    Addiction is a prevalent and growing concern in all aspects of our modern society. There are considerable concerns for the growing frequency of addictions to drugs, alcohol, gambling, eating, and even sex. Though exercise is generally accepted as a positive behaviour that has many benefits associated with enhanced physical and psychological wellbeing, there is an increasing awareness that exercise addiction is becoming a common phenomenon. Theories regarding how exercise can become addictive, and studies of withdrawal from exercise are reviewed. Several physiological mechanisms, including endogenous opioids, catecholamines, functional asymmetry of brain activity and thermoregulation have been implicated in exercise dependence.

    A growing line of research has shown positive treatment outcomes from technology-based therapy for substance use disorders (SUDs). However, little is known about the effectiveness of technology-based SUD interventions for persons who already had numerous prior SUD treatments. We conducted a secondary analysis on a 12-month trial with patients (N=160) entering methadone maintenance treatment (MMT). Patients were randomly assigned to either standard MMT treatment or a model in which half of standard counseling sessions were replaced with a computer-based intervention, called Therapeutic Education System (standard+TES). Four treatment history factors at baseline, the number of lifetime SUD treatment episodes, detoxification episodes, and inpatient/outpatient treatment episodes were categorized into three levels based on their tertile points, and analyzed as moderators. Dependent variables were urine toxicology results for opioid and cocaine abstinence for 52-weeks. The standard+TES condition produced significantly better opioid abstinence than standard treatment for participants with 1) a moderate or high frequency of lifetime SUD treatment episodes, and 2) those with all three levels (low, moderate and high) of detoxification and inpatient/outpatient treatment episodes, pshistory, pstechnology-based behavioral therapy as part of treatment can be more effective than MMT alone, even among patients with a history of multiple addiction treatment episodes.

    Maladaptive use of the Internet results in Internet addiction (IA), which is associated with various negative consequences. Molecular and functional imaging techniques have been increasingly used for analysis of neurobiological changes and neurochemical correlates of IA. This review summarizes molecular and functional imaging findings on neurobiological mechanisms of IA, focusing on magnetic resonance imaging (MRI) and nuclear imaging modalities including positron emission tomography (PET) and single photon emission computed tomography (SPECT). MRI studies demonstrate that structural changes in frontal cortex are associated with functional abnormalities in Internet addicted subjects. Nuclear imaging findings indicate that IA is associated with dysfunction of the brain dopaminergic systems. Abnormal dopamine regulation of the prefrontal cortex (PFC) could underlie the enhanced motivational value and uncontrolled behavior over Internet overuse in addicted subjects. Further investigations are needed to determine specific changes in the Internet addictive brain, as well as their implications for behavior and cognition.

    Highlights of a systematic analysis of the abstracts of over 1700 publications dealing with addictive drugs (primarily alcohol) in the context of animal learning and motivation are summarized under two main headings. The behavioral effects of drugs vary with the nature of the drug, the dosage, and the behavioral baseline; behavioral tolerance frequently results from continued practice in the drug state. The paradigmatic effects show that drugs can function effectively as conditional stimuli, unconditional stimuli, responses, and reinforcers. As a result, drug habits develop their own motivational support, leading to conditioned tolerance and conditioned addiction. It is contended that principles of animal behavior can provide a basis for a theory of human drug use and abuse, but that voluntary control of addictive behavior requires uniquely human cognitive processes.

    2012-08-01

    Craving for a particular substance is an essential characteristic of addictive behavior. Increasing evidence suggests that food cravings and excessive food consumption could similarly be due to addictive processes. Recently, the Yale Food Addiction Scale (YFAS) was introduced for identifying individuals with addictive eating patterns. We conducted an online study (n=616, 75.8% female) in which participants filled out the YFAS and the Food Cravings Questionnaire-Trait (FCQ-T). Participants diagnosed as being addicted to food using the YFAS had higher scores on all food craving subscales except for anticipation of positive reinforcement that may result from eating. In a subsequent regression analysis, all food craving subscales positively predicted food addiction symptoms while positive reinforcement negatively predicted food addiction symptoms. Similar to other addictive behaviors, results indicate that individuals with addictive eating patterns experience more food cravings, but concurrently do not expect a positive reinforcement through eating.

    Full Text Available The view that anatomically distinct memory systems differentially contribute to the development of drug addiction and relapse has received extensive support. The present brief review revisits this hypothesis as it was originally proposed twenty years ago (White, 1996 and highlights several recent developments. Extensive research employing a variety of animal learning paradigms indicates that dissociable neural systems mediate distinct types of learning and memory. Each memory system potentially contributes unique components to the learned behavior supporting drug addiction and relapse. In particular, the shift from recreational drug use to compulsive drug abuse may reflect a neuroanatomical shift from cognitive control of behavior mediated by the hippocampus/dorsomedial striatum toward habitual control of behavior mediated by the dorsolateral striatum (DLS. In addition, stress/anxiety may constitute a cofactor that facilitates DLS-dependent memory, and this may serve as a neurobehavioral mechanism underlying the increased drug use and relapse in humans following stressful life events. Evidence supporting the multiple systems view of drug addiction comes predominantly from studies of learning and memory that have employed as reinforcers addictive substances often considered within the context of drug addiction research, including cocaine, alcohol, and amphetamines. In addition, recent evidence suggests that the memory systems approach may also be helpful for understanding topical sources of addiction that reflect emerging health concerns, including marijuana use, high-fat diet, and video game playing.

  8. Food Addiction in the Light of DSM-5

    Directory of Open Access Journals (Sweden)

    Adrian Meule

    2014-09-01

    Full Text Available The idea that specific kind of foods may have an addiction potential and that some forms of overeating may represent an addicted behavior has been discussed for decades. In recent years, the interest in food addiction is growing and research on this topic lead to more precise definitions and assessment methods. For example, the Yale Food Addiction Scale has been developed for the measurement of addiction-like eating behavior based on the diagnostic criteria for substance dependence of the fourth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV. In 2013, diagnostic criteria for substance abuse and—dependence were merged, thereby increasing the number of symptoms for substance use disorders (SUDs in the DSM-5. Moreover, gambling disorder is now included along SUDs as a behavioral addiction. Although a plethora of review articles exist that discuss the applicability of the DSM-IV substance dependence criteria to eating behavior, the transferability of the newly added criteria to eating is unknown. Thus, the current article discusses if and how these new criteria may be translated to overeating. Furthermore, it is examined if the new SUD criteria will impact future research on food addiction, for example, if “diagnosing” food addiction should also be adapted by considering all of the new symptoms. Given the critical response to the revisions in DSM-5, we also discuss if the recent approach of Research Domain Criteria can be helpful in evaluating the concept of food addiction.

  11. Addiction and choice: Theory and new data

    Directory of Open Access Journals (Sweden)

    Gene M Heyman

    2013-05-01

    Full Text Available Addiction’s biological basis has been the focus of much research. The findings have persuaded experts and the public that drug use in addicts is compulsive. But the word compulsive identifies patterns of behavior. Thus, the question is not whether addiction has a biology, but whether it is sensible to say that addicts use drugs compulsively. Research shows most of those who meet the American Psychiatric Association’s criteria for addiction quit using illegal drugs by age thirty, that they usually quit without professional help, and that the correlates of quitting include legal concerns, economic pressures, and the desire for respect, particularly from family members. That is, the correlates of quitting are the correlates of choice. However, addiction is, by definition, a disorder, and thereby not beneficial in the long run. This is precisely the pattern of choices predicted by quantitative choice principles, such as the matching law, melioration, and hyperbolic discounting. Although the brain disease model of addiction is perceived by many as received knowledge it is not supported by research or logic. In contrast, well established, quantitative choice principles predict both the possibility and the details of addiction.

    In this article we summarized the recent research of the food addiction, diagnosis, treatment and prevention, which is carried out in this area. The concept of food addiction is new and complex, but proven to be very important for understanding and solving the problem of obesity. First part of this paper emphasizes the neurological studies, whose results indicate the similarity of brain processes that are being activated during drug abuse and during eating certain types of food. In this context, different authors speak of "hyper-palatable", industrial food, saturated with salt, fat and sugar, which favor an addiction. In the section on diagnostic and instruments constructed for assessing the degree of dependence, main diagnostic tool is standardized Yale Food Addiction Scale constructed by Ashley Gearhardt, and her associates. Since 2009, when it was first published, this scale is used in almost all researches in this area and has been translated into several languages. Finally, distinguish between prevention and treatment of food addiction was made. Given that there were similarities with other forms of addictive behavior, the researchers recommend the application of traditional addiction treatment. PMID:25751444

    Converging evidence from clinical, animal, and neuroimaging experiments suggests that the addictive behavior is associated with dysregulated dopamine neurotransmission. The precise role of dopamine in establishment and maintenance of addiction however is unclear. In this context animal studies on the brain reward system and the associative memory processing provide a novel insight. It was shown that both processing involve dopamine neurotransmission and both are disrupted in addiction. These ...

    2013-04-01

    Neuronal nicotinic acetylcholine receptors (nAChRs) are ligand-gated ion channels that consist of pentameric combinations of α and β subunits. These receptors are widely distributed throughout the brain and are highly expressed in addiction circuitry. The role of nAChRs in regulating neuronal activity and motivated behavior is complex and varies both in and among brain regions. The rich diversity of central nAChRs has hampered the characterization of their structure and function with use of classic pharmacological techniques. However, recent molecular approaches using null mutant mice with specific regional lentiviral re-expression, in combination with neuroanatomical and electrophysiological techniques, have allowed the elucidation of the influence of different nAChR types on neuronal circuit activity and behavior. This review will address the influence of nAChRs on limbic dopamine circuitry and the medial habenula-interpeduncular nucleus complex, which are critical mediators of reinforced behavior. Characterization of the mechanisms underlying regulation of addiction pathways by endogenous cholinergic transmission and by nicotine may lead to the identification of new therapeutic targets for treating tobacco dependence and other addictions.

    Full Text Available Abstract Children living with substance abusers are more likely to experience negative outcomes. Our goal was to compare caregivers' reports on the Child Behavior Checklist (CBCL and a socioeconomic and risk form of psychological aspects of children exposed to substance abuse assisted versus not assisted by a preventive intervention program in an underprivileged community. This observational intervention study was conducted with 66 caregivers of children who attended the program and 35 caregivers of children from the same community who did not attend. Ages ranged between six and 11 years old. Chi-square and logistic regression tests indicate that children exposed to substance abusers have more mental health problems than the general population and those who did not participate in the preventive intervention program presented worse outcomes, with higher rates of behavioral/emotional problems and exposure to risk situations. Results suggest that preventive actions might be helpful to promote the mental health of children at risk, validating the need for public policies and services.

    Exercise and sports activity are beneficial both physically and psychologically but excessive exercise may have adverse physiological and psychological effects. There are methodological issues in the definition, diagnosis and etiology of exercise addiction. Several questionnaires and diagnostic tools have been developed and validated and they show high validity and reliability. Exercise addiction has been suggested as having an obsessive-compulsive dimension as well as rewarding aspects that may include it among the behavioral addictions. Biological studies show that in rodents, exercise such as wheel running activates the dopamine reward system and thus contributing to stress reduction. Further evidence suggests that running is associated with endorphins and cannabinoids thus explaining the "runners high" or euphoric feelings that may lead to exercise addiction. Genetic studies suggest that genes which control preference for drugs also control the preference for naturally rewarding behaviors such as exercise. Psychological studies also explain exercise addiction in terms of reward, habituation, social support, stress-relief, avoidance of withdrawal and reduction of anxiety. It has been suggested that exercise addiction is a part of a continuum of sportive activity that develops in stages from the recreational exercise to at-risk exercise, problematic exercise and finally into exercise addiction. Assessment and treatment should take into account the various stages of exercise addiction development, its comorbidity with other psychiatric disorders such as eating disorders or substance use and alcohol disorders. Treatment approaches for exercise addiction are based on the cognitive-behavioral approach but little is known about their effectiveness. A single-case study shows promise of pharmacological treatment for exercise addiction and further studies are required. This review summarizes diagnostic and phenomenology of exercise addiction with emphasis on

    2016-08-01

    Addiction is a major public health problem with few efficacious and safe treatments. The goal of this review is to provide an evidence-based assessment of the therapeutic role of the opioid antagonist naltrexone across the addiction spectrum-substance-based and behavioral. The PubMed database was searched for randomized, placebo-controlled clinical trials that investigated the oral or intramuscular long-acting formulation of naltrexone in substance use disorders or behavioral addictions such as pathological gambling, kleptomania, and trichotillomania. Thirty-nine efficacy studies were retrieved, covering alcohol use disorder (n = 22), opioid use disorder (n = 6), nicotine use disorder (n = 5), stimulant use disorder (n = 2), gambling disorder (n = 2), trichotillomania (n = 1), and kleptomania (n = 1). Despite the very different presentations within and between both addiction categories, the data, as a whole, show consistency in favor of naltrexone's relative efficacy and safety. Given the potential benefit and good tolerability revealed in the studies, the high morbidity associated with addiction, and the dearth of alternate treatments, naltrexone would seem like an underutilized treatment option. Further, naltrexone's seemingly broad anti-addiction efficacy supports a shared role for brain opioid pathways in the pathophysiology of addiction, broadly defined. More studies investigating the efficacy and tolerability of naltrexone and other opioid modulators are warranted. Studies should also further examine the effect of combining psychotherapy with naltrexone, as well as the potential role of naltrexone in treating comorbid addictions. PMID:27401883

    Full Text Available Objective: Although cognitive behavioral model of Internet addiction has been well described, studies on metacognitions and ruminative response styles related with Internet addiction are very limited. The aim of the present study was to compare metacognitions and ruminative response style in Internet addicts with a healthy control group. Method: The study included 30 males who presented to our Internet Addiction Outpatient clinic, and diagnosed with Internet addiction, and a control group of 30 healthy males with similar sociodemographic characteristics. A sociodemographic data form, Internet Addiction Test (IAT, Metacognitions Questionnaire (MCQ-30, Ruminative Response Scale-short version (RRS-SV, and Beck Depression Inventory (BDI were used for data collection. Results: The MCQ-30 total, MCQ-30 uncontrollability and danger score, MCQ-30 need to control thoughts score and RRS-SV scores statistically significantly higher in study group compared the control group. After correcting for BDI by ANCOVA, the difference between MCQ-30 total score and RRS-SV disappeared. Conclusion: Internet addicts show ruminative responses instead of having an effective problem-solving attitude and defining problems; and this self-focused rumination leads an individual to recall more reinforced memories about the Internet so that the problem of Internet addiction becomes deeper. As a result of this study, although Internet addiction is accompanied by depression primarily or secondarily, manifestation of Internet addiction is exacerbated by depression through ruminative responses and metacognitions

    2016-08-01

    While considerable efforts have been made to understand the neurobiological basis of substance addiction, the potentially "addictive" qualities of repetitive behaviors, and whether such behaviors constitute "behavioral addictions," is relatively neglected. It has been suggested that some conditions, such as gambling disorder, compulsive stealing, compulsive buying, compulsive sexual behavior, and problem Internet use, have phenomenological and neurobiological parallels with substance use disorders. This review considers how the issue of "behavioral addictions" has been handled by latest revisions of the Diagnostic and Statistical Manual of Mental Disorders (DSM) and the International Classification of Diseases (ICD), leading to somewhat divergent approaches. We also consider key areas for future research in order to address optimal diagnostic classification and treatments for such repetitive, debilitating behaviors. PMID:27151528

    Addiction to a wide range of substances of abuse has been suggested to reflect a ‘Reward Deficiency Syndrome'. That is, drugs are said to stimulate the reward mechanisms so intensely that, to compensate, the population of dopamine D2 receptors (DD2R) declines. The result is that an increased intake is necessary to experience the same degree of reward. Without an additional intake, cravings and withdrawal symptoms result. A suggestion is that food addiction, in a similar manner to drugs of abu...

    Addiction to MOP-r agonists such as heroin (and also addiction to prescription opioids) has reemerged as an epidemic in the twenty first century, causing massive morbidity. Understanding the genetics contributing to susceptibility to this disease is crucial for the identification of novel therapeutic targets, and also for discovery of genetic markers which would indicate relative protection or vulnerability from addiction, and relative responsiveness to pharmacotherapy. This information could thus eventually inform clinical practice. In this review, we focus primarily on association studies of heroin and opiate addiction, and further describe the studies which have been replicated in this field, and are thus more likely to be useful for translational efforts.

  19. Addiction, adolescence, and innate immune gene induction

    Directory of Open Access Journals (Sweden)

    Fulton T Crews

    2011-04-01

    Full Text Available Repeated drug use/abuse amplifies psychopathology, progressively reducing frontal lobe behavioral control and cognitive flexibility while simultaneously increasing limbic temporal lobe negative emotionality. The period of adolescence is a neurodevelopmental stage characterized by poor behavioral control as well as strong limbic reward and thrill seeking. Repeated drug abuse and/or stress during this stage increase the risk of addiction and elevate activator innate immune signaling in the brain. Nuclear factor-kappa-light-chain-enhancer of activated B cells (NF-κB is a key glial transcription factor that regulates proinflammatory chemokines, cytokines, oxidases, proteases, and other innate immune genes. Induction of innate brain immune gene expression (e.g., NF-κB facilitates negative affect, depression-like behaviors, and inhibits hippocampal neurogenesis. In addition, innate immune gene induction alters cortical neurotransmission consistent with loss of behavioral control. Studies with anti-oxidant, anti-inflammatory, and anti-depressant drugs as well as opiate antagonists link persistent innate immune gene expression to key behavioral components of addiction, e.g. negative affect-anxiety and loss of frontal cortical behavioral control. This review suggests that persistent and progressive changes in innate immune gene expression contribute to the development of addiction. Innate immune genes may represent a novel new target for addiction therapy.

  2. Pleasure and Addiction

    2013-09-01

    Full Text Available What is the role and value of pleasure in addiction? Foddy and Savalescu (2010 have claimed that substance use is just pleasure-oriented behaviour. They describe addiction as ‘strong appetites toward pleasure’ and argue that addicts suffer in significant part because of strong social and moral disapproval of lives dominated by pleasure seeking. But such lives, they claim, can be autonomous and rational. The view they offer is largely in line with the choice model and opposed to a disease model of addiction. Foddy and Savulescu are sceptical of self-reports that emphasize the ill effects of addiction such as loss of family and possessions, or that claim an absence of pleasure after tolerance sets in. Such reports they think are shaped by social stigma which makes available a limited set of socially approved addiction narratives. We will not question the claim that a life devoted to pleasure can be autonomously chosen. Nor do we question the claim that the social stigma attached to the use of certain drugs increases the harm suffered by the user. However our interviews with addicts (as philosophers rather than health professionals or peers reveal a genuinely ambivalent and complex relationship between addiction, value and pleasure. Our subjects did not shy away from discussing pleasure and its role in use. But though they usually valued the pleasurable properties of substances, and this played that did not mean that they valued an addictive life. Our interviews distinguished changing attitudes towards drug related pleasures across the course of substance use, including diminishing pleasure from use over time and increasing resentment at the effects of substance use on other valued activities. In this paper we consider the implications of what drug users say about pleasure and value over the course of addiction for models of addiction.

    More than 80% of addicted individuals fail to seek treatment, which might reflect impairments in recognition of severity of disorder. Considered by some as intentional deception, such 'denial' might instead reflect dysfunction of brain networks subserving insight and self-awareness. Here we review the scant literature on insight in addiction and integrate this perspective with the role of: (i) the insula in interoception, self-awareness and drug craving; (ii) the anterior cingulate in behavioral monitoring and response selection (relevant to disadvantageous choices in addiction); (iii) the dorsal striatum in automatic habit formation; and (iv) drug-related stimuli that predict emotional behavior in addicted individuals, even without conscious awareness. We discuss implications for clinical treatment including the design of interventions to improve insight into illness severity in addiction.

The percentage of patients addicted only to benzodiazepines was higher among females than males. Benzodiazepine consumption had started as a drug addiction behavior in only 10% of cases. The main sources of prescription identified were general practitioners (52% of cases or compliant pharmacists (25%. Overall, 15 different benzodiazepines were abused, with lormetazepam being the most commonly used (by 123 patients, 43.8% of the total.Conclusion: Our data show that, outside the population of multidrug addicts, there is an underestimated group of chronic benzodiazepine consumers who are often not referred to medical institutions for treatment. Even in the group of patients addicted to one substance only, we observed an abnormal number of requests for detoxification from lormetazepam, which appears to be more "popular" than other benzodiazepines. This drug should be prescribed according to stricter criteria and submitted to closer control.Keywords: lormetazepam, benzodiazepines, addiction, inpatient detoxification

    Cocaine use leads to health, social and legal problems. The aim of this paper is to discuss cocaine action, addicts characteristics, use patterns and consequences, as well as addiction treatment methods. A literature review was based on the Medline, PubMed, Polish Medical Bibliography databases and the Silesian Library resources. The Police and Central Statistical Office statistics, as well as the World Health Organization, the European Monitoring Centre for Drugs and Drug Addiction and the National Office for Combating Drug Addiction reports were used. Cocaine leads to mood improvement, appetite decrease, physical and intellectual activity enhancement, euphoria, inflated self-esteem, social networking ease and increased sexual desire. Cocaine hydrochloride is mainly used intranasaly, but also as intravenous and subcutaneous injections. Cocaine use and first addiction treatment fall in later age compared to other psychoactive substances. There is a high men to women ratio among addicts. There is a relationship between cocaine addiction, the presence of other disorders and genetic predisposition to addiction development. Polish reports indicate higher popularity of cocaine among people with a high economic and social status. Although Poland is a country with the low percentage of cocaine use, its popularity is growing. The consequences of cocaine use concern somatic and mental health problems, socioeconomic and legal conditions. The drug plays a role in crimes and traffic accidents. Because of the risks associated with cocaine use, it has been listed in a register of drugs attached to the Act on Counteracting Drug Addiction. Addiction treatment includes psychological, pharmacological and harm reduction strategies. Med Pr 2016;67(4):537-544. PMID:27623834

    Objectives There remains limited consensus regarding the definition and conceptual basis of exercise addiction. An understanding of the factors motivating maintenance of addictive exercise behavior is important for appropriately targeting intervention. The aims of this study were twofold: first, to establish consensus on features of an exercise addiction using Delphi methodology and second, to identify whether these features are congruous with a conceptual model of exercise addiction adapted from the Work Craving Model. Methods A three-round Delphi process explored the views of participants regarding the features of an exercise addiction. The participants were selected from sport and exercise relevant domains, including physicians, physiotherapists, coaches, trainers, and athletes. Suggestions meeting consensus were considered with regard to the proposed conceptual model. Results and discussion Sixty-three items reached consensus. There was concordance of opinion that exercising excessively is an addiction, and therefore it was appropriate to consider the suggestions in light of the addiction-based conceptual model. Statements reaching consensus were consistent with all three components of the model: learned (negative perfectionism), behavioral (obsessive-compulsive drive), and hedonic (self-worth compensation and reduction of negative affect and withdrawal). Conclusions Delphi methodology allowed consensus to be reached regarding the features of an exercise addiction, and these features were consistent with our hypothesized conceptual model of exercise addiction. This study is the first to have applied Delphi methodology to the exercise addiction field, and therefore introduces a novel approach to exercise addiction research that can be used as a template to stimulate future examination using this technique.

    Individual differences are a hallmark of drug addiction. Here, we describe a rat model based on differential initial responsiveness to low dose cocaine. Despite similar brain cocaine levels, individual outbred Sprague-Dawley rats exhibit markedly different magnitudes of acute cocaine-induced locomotor activity and, thereby, can be classified as low or high cocaine responders (LCRs or HCRs). LCRs and HCRs differ in drug-induced, but not novelty-associated, hyperactivity. LCRs have higher basal...

  13. How prevalent is 'food addiction'?

    Full Text Available Increasing evidence suggests that binge eating-related disorders could be related to addiction-like eating patterns due to the addictive potential of hyperpalatable foods. Subsequently, important implications have been derived for treatment of those disorders and even political actions. However, studies on the prevalence of food addiction are rare. Few recent studies investigated addictive eating in children, adolescents, and adults. This mini-review presents these first attempts to assess addictive eating and how prevalent addictive eating patterns were in the respective studies. It is concluded that the prevalence of food addiction is increased in obese individuals and even more so in obese patients with binge eating disorder. However, prevalence of food addiction is not sufficient to account for the obesity epidemic. Conversely, an arguably high prevalence of food addiction can also be found in under-, normal-, and overweight individuals. Future studies may investigate which factors are associated with addictive eating in non-obese individuals.

    Gambling is pertinent to neuroscience research for at least two reasons. First, gambling is a naturalistic and pervasive example of risky decision making, and thus gambling games can provide a paradigm for the investigation of human choice behavior and “irrationality.” Second, excessive gambling involvement (i.e., pathological gambling) is currently conceptualized as a behavioral addiction, and research on this condition may provide insights into addictive mechanisms in the absence of exogeno...

    Full Text Available We investigate the effect of different scales of addictive factors on the utilization of medical services in this paper using a two-part model. Data are from the 2005 National Health Interview Survey and the claims data in the National Health Insurance Research Database in Taiwan. The results show that personal addictive behavior is significantly associated with both outpatient and inpatient utilization. Moreover, our result implies that those who smoked at least 20 cigarettes per day might not visit a doctor until the illness was severe. It suggests that the government can accomplish these goals by promotion and education in order to increase public awareness of personal health.

    Excessive computer game (CG) playing may cause not only behavioral addiction, but also potential negative effects on developing brain. It is necessary to reveal how brain is affected by excessive use of CG playing and behavioral addiction of it. By using PET, we address the issue seeking to identifying patterns of regional brain activation associated with behavioral addiction and excessive use of CG playing by adolescents. 6 normal control and 8 adolescents who were met by the criteria of behavioral addiction on the survey as addiction groups with an addiction of CG playing were participated. Initial screening survey which is the adapted version of DSM-IV for pathologic gambling was done. PET were performed twice in each participants both during resting state and after 20 min playing of CG. Psychological test including Youth Self Report (YSR), memory and attention test and vocabulary item from KWAIS were performed. Scores of the vocabulary item from KWAIS and social competence from YSR were significantly lower in the addiction group. On PET, addiction group showed higher resting metabolism on inferior frontal, premotor, prefrontal and superior temporal area. Adolescents with addiction of CG revealed different patterns of regional brain activation comparing to control groups. These suggest behavioral addiction and excessive use of CG may result in functional alteration of developing brain in adolescents.

  1. Review of current researches on internet addiction

    International Nuclear Information System (INIS)

    Internet addiction (IA) is a mental illness emerged in recent years with increasing use of computer and internet. The serious consequences such as mental and physical illness and social function impairment caused by IA have attracted extensive attention of the whole society. IA affects human beings at a high prevalence all over the world which has highlighted the importance of prevention and treatment of IA. Although there is still debate about definition of IA, increasing evidences including the result from genetic research,neurobiology study and clinical manifestation show that IA may share the same mechanisms with substance addiction, and be probably classified as behavioral addiction which is represented by pathological gambling. However, since the study on IA is yet on the initial stage and neuro biological research on IA is still limited, more reliable investigations especially neuro biological research remains uppermost in this area.

    Sport is widely encouraged as it is beneficial for health. However, high-performance sport is more and more associated to rather suspicious practices; doping is one of the best example. From a physician point of view, the use of doping agents is obviously a major concern because taking such products often induce serious adverse effects on health. The present manuscript aims to inform physicians about the most frequent doping practices. It also points out that intensive sport can generate an "addictive" behavior sharing with "common"addictions a loss of practice control, a lack of interest in other activities and even a sport's practice detrimental to athlete's health. Analysis of the doping issue needs to take this reality into account as some doping products display an established " addictive" effect.

    Alcohol and other drugs of abuse have significant impacts on the neuroimmune system. Studies have demonstrated that drugs of abuse interact with the neuroimmune system and alter neuroimmune gene expression and signaling, which in turn contribute to various aspects of addiction. As the key component of the CNS immune system, neuroimmune factors mediate neuroinflammation and modulate a wide range of brain function including neuronal activity, endocrine function, and CNS development. These neuromodulatory properties of immune factors, together with their essential role in neuroinflammation, provide a new framework to understand neuroimmune mechanisms mediating brain functional and behavioral changes contributing to addiction. This chapter highlights recent advances in understanding neuroimmune changes associated with exposure to alcohol and other drugs of abuse, including opiates, marijuana, methamphetamine, and cocaine. It provides a brief overview on what we know about neuroimmune signaling and its role in drug action and addiction. PMID:25175859

    Over the last few years, the concept of food addiction has become a common feature in the scientific literature, as well as the popular press. Nevertheless, the use of the term addiction to describe pathological aspects of food intake in humans remains controversial, and even among those who affirm the validity of the concept, there is considerable disagreement about its utility for explaining the increasing prevalence of obesity throughout much of the world. An examination of the literature on food addiction indicates that mesolimbic and nigrostriatal dopamine systems often are cited as mechanisms that contribute to the establishment of food addiction. However, in reviewing this literature, it is important to have a detailed consideration of the complex nature of dopaminergic involvement in motivational processes. For example, although it is often stated that mesolimbic dopamine mediates reward, there is no standard or consistent technical meaning of this term. Moreover, there is a persistent tendency to link dopamine transmission with pleasure or hedonia, as opposed to other aspects of motivation or learning. The present article provides a critical discussion of some aspects of the food addiction literature, viewed through the lens of recent findings and current theoretical views of dopaminergic involvement in food motivation. Furthermore, compulsive food intake and binge eating will be considered from an evolutionary perspective, in terms of the motivational subsystems that are involved in adaptive patterns of food consumption and seeking behaviors and a consideration of how these could be altered in pathological conditions.

  5. The Emergence of a Circuit Model for Addiction.

    Addiction is a disease of altered behavior. Addicts use drugs compulsively and will continue to do so despite negative consequences. Even after prolonged periods of abstinence, addicts are at risk of relapse, particularly when cues evoke memories that are associated with drug use. Rodent models mimic many of the core components of addiction, from the initial drug reinforcement to cue-associated relapse and continued drug intake despite negative consequences. Rodent models have also enabled unprecedented mechanistic insight into addiction, revealing plasticity of glutamatergic synaptic transmission evoked by the strong activation of mesolimbic dopamine-a defining feature of all addictive drugs-as a neural substrate for these drug-adaptive behaviors. Cell type-specific optogenetic manipulations have allowed both identification of the relevant circuits and design of protocols to reverse drug-evoked plasticity and to establish links of causality with drug-adaptive behaviors. The emergence of a circuit model for addiction will open the door for novel therapies, such as deep brain stimulation. PMID:27145911

    This study investigated childhood psychopathology and Internet addiction in adolescents. Initial assessment data were obtained from 1998 to 1999, and a follow-up assessment was performed in 2006, when the original subjects entered middle school. Personal information for the 524 male subjects was obtained from the original data. The subjects were evaluated with the Korean version of the child behavior checklist, which was administered to the children's parents. Demographic and psychosocial factors were also evaluated. Children were reassessed with the self-reported Korea Internet Addiction Scale. Our results indicated that 3.6 % of the subjects had Internet addiction, and revealed a significant relationship between withdrawal and anxiety/depression and future Internet addiction. The results suggest that withdrawal and anxiety/depression during childhood should be considered in the etiology of problematic Internet use in boys. Accordingly, clinicians should consider anxiety/depression and withdrawal during childhood to prevent Internet addiction.

    Full Text Available Obesity is a global issue and it has been suggested that an addiction to certain foods could be a factor contributing to overeating and subsequent obesity. Only one tool, the Yale Food Addiction Scale (YFAS has been developed to specifically assess food addiction. This review aimed to determine the prevalence of food addiction diagnosis and symptom scores, as assessed by the YFAS. Published studies to July 2014 were included if they reported the YFAS diagnosis or symptom score and were published in the English language. Twenty-five studies were identified including a total of 196,211 predominantly female, overweight/obese participants (60%. Using meta-analysis, the weighted mean prevalence of YFAS food addiction diagnosis was 19.9%. Food addiction (FA diagnosis was found to be higher in adults aged >35 years, females, and overweight/obese participants. Additionally, YFAS diagnosis and symptom score was higher in clinical samples compared to non-clinical counterparts. YFAS outcomes were related to a range of other eating behavior measures and anthropometrics. Further research is required to explore YFAS outcomes across a broader spectrum of ages, other types of eating disorders and in conjunction with weight loss interventions to confirm the efficacy of the tool to assess for the presence of FA.

    Nurses have demonstrated concern for years about their interactions with pregnant women who abuse drugs. Reports of nurses' concern with substance abuse have been reported in the literature since the 1980s. As with any chronic disease, drug addiction causes physiologic changes, and the pathology that occurs in the brain drives characteristic behaviors. Research suggests that choices that addicts make are driven by pathology rather than by failure of a moral compass. This article reviews the theoretical explanations for addictive behaviors, describes the pathophysiology of drug addiction that is responsible for the predictable symptoms and behaviors exhibited by women who abuse prescription drugs and other opioids, and identifies nursing interventions to impact positive outcomes. Nurses who have a working knowledge of this disease will provide more effective nursing care to the women they encounter and are better prepared to make a difference in the lives of both women and their children.

The study was conducted on 33 drug addicts who were admitted to hospital for treatment. They were males with age range (19-30; mean 24.73 years. They were followed up at 2-weeks intervals for one month. Blood samples from 18 addicts and 10 non-drug-user control blood donors were evaluated for some lymphocyte immunophenotypic markers by flow cytometric analysis. Addicts showed significantly (P < 0.001 decreased percentages of both T-helper (CD4+ and T-cytotoxic (CD8+ compared with controls. There was also significant (P < 0.05 reduction of CD4+/CD8+ lymphocyte ratio. Sera from all addicts, whether on hospital admission or follow-up samples were subjected to the following investigations. Some blood-borne viral infections were investigated; hepatitis B surface antigen (HBsAg was present in 1/33 (3% addicts. Hepatitis C virus antibodies (anti-HCV were detected in 11/33 (33.3% addicts versus 1/10 (10% of controls. Human immunodeficiency virus antibodies (anti-HIV were present in one serum out of 33 (3% addicts. Reactivation of cytomegalovirus (CMV latent infection was assessed by detection of anti-CMV IgM in 1/33 (3% of addicts on hospital admission, which persisted during the first two weeks, then disappeared on the 4th week. Antibody activity as neutralizing antibodies to polioviruses 1,2 and 3 were tested in cell culture, the antibody titer was higher in follow-up samples than on the time of hospital admission. Antistreptolysin O (ASO was detected in serum of one addict (3% on hospital admission and in another addict 2-weeks later which indicated streptococcal infection.

    Drug addiction is a chronic relapsing disease in which drug administration becomes the primary stimulus that drives behavior regardless of the adverse consequence that may ensue. As drug use becomes more compulsive, motivation for natural rewards that normally drive behavior decreases. The discontinuation of drug use is associated with somatic signs of withdrawal, dysphoria, anxiety and anhedonia. These consequences of drug use are thought to contribute to the maintenance of drug use and to t...

    Drug addiction is marked by continued drug-seeking behavior despite deleterious consequences and a heightened propensity to relapse notwithstanding long, drug-free periods. The enduring nature of addiction has been hypothesized to arise from perturbations in intracellular signaling, gene expression, and brain circuitry induced by substance abuse. Ameliorating some of these aberrations should abate behavioral and neurochemical markers associated with an “addiction phenotype”. This review summa...

    Recent studies show similarities between cybersex addiction and substance dependencies and argue to classify cybersex addiction as a behavioral addiction. In substance dependency, implicit associations are known to play a crucial role, and such implicit associations have not been studied in cybersex addiction, so far. In this experimental study, 128 heterosexual male participants completed an Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998) modified with pornographic pictures. Further, problematic sexual behavior, sensitivity towards sexual excitation, tendencies towards cybersex addiction, and subjective craving due to watching pornographic pictures were assessed. Results show positive relationships between implicit associations of pornographic pictures with positive emotions and tendencies towards cybersex addiction, problematic sexual behavior, sensitivity towards sexual excitation as well as subjective craving. Moreover, a moderated regression analysis revealed that individuals who reported high subjective craving and showed positive implicit associations of pornographic pictures with positive emotions, particularly tended towards cybersex addiction. The findings suggest a potential role of positive implicit associations with pornographic pictures in the development and maintenance of cybersex addiction. Moreover, the results of the current study are comparable to findings from substance dependency research and emphasize analogies between cybersex addiction and substance dependencies or other behavioral addictions.

    Carroll, Marilyn E; Lynch, Wendy J

    2016-09-01

    The importance of studying sex as a biological variable in biomedical research is becoming increasingly apparent. There is a particular need in preclinical studies of addiction to include both sexes, as female animals are often excluded from studies, leaving large gaps in our knowledge of not only sex differences and potential prevention and treatment strategies but also with regard to the basic neurobiology of addiction. This review focuses on methodology that has been developed in preclinical studies to examine sex differences in the behavioral aspects and neurobiological mechanisms related to addiction across the full range of the addiction process, including initiation (acquisition), maintenance, escalation, withdrawal, relapse to drug seeking and treatment. This review also discusses strategic and technical issues that need to be considered when comparing females and males, including the role of ovarian hormones and how sex differences interact with other major vulnerability factors in addiction, such as impulsivity, compulsivity and age (adolescent versus adult). Novel treatments for addiction are also discussed, such as competing non-drug rewards, repurposed medications such as progesterone and treatment combinations. Practical aspects of conducting research comparing female and male animals are also considered. Making sex differences a point of examination requires additional effort and consideration; however, such studies are necessary given mounting evidence demonstrating that the addiction process occurs differently in males and females. These studies should lead to a better understanding of individual differences in the development of addiction and effective treatments for males and females. PMID:27345022

    Parenting attitudes of female heroin addicts were investigated in a single factor design which compared addict mothers, addict non-mothers, nonaddict mothers, and nonaddict nonmothers. A principal components factor analysis was performed on the PARI and used as the dependent measure. A factor labeled "authoritarian overinvolvement" emerged which significantly differentiated between groups. Further, the effects of mothering and addiction proved to be additive such that addict mothers were extremely high on this scale. This result was discussed in terms of the parental home environment of addict women.

    Full Text Available In this paper we contend that the psychology of addiction is similar to the psychology of ordinary, non-addictive temptation in important respects, and explore the ways in which these parallels can illuminate both addiction and ordinary action. The incentive salience account of addiction proposed by Robinson and Berridge (1993; 2001; 2008 entails that addictive desires are not in their nature different from many of the desires had by non-addicts; what is different is rather the way that addictive desires are acquired, which in turn affects their strength. We examine these 'incentive salience' desires, both in addicts and non-addicts, contrasting them with more cognitive desires. On this account the self-control challenge faced by addicted agents is not different in kind from that faced by non-addicted agents—though the two may, of course, differ greatly in degree of difficulty. We explore a general model of self-control for both the addict and the non-addict, stressing that self-control may be employed at three different stages, and examining the ways that it might be strengthened. This helps elucidate a general model of intentional action.

    Behavioral addictions, especially pathological gambling and internet addiction, have become a growing concern in research and health policy. Similarities between behavioral addictions and substance dependency are currently being discussed in the scientific community. Unfortunately the number of scientific studies on pathological gambling and internet addiction is still very low. The estimated prevalence of pathological gambling among the German population is 0.2-0.5%. These numbers are comparable to prevalence rates reported for illegal drug dependency. About 1.5 million people, i.e. 3% of the German population, are believed to be at risk of internet addiction. Therefore, it is important to investigate in more detail the clinical and neuroscientific basis of pathological gambling and internet addiction. In this review we summarize the current status of research regarding pathological gambling and internet addiction and outline possible future research perspectives in the field of neuroimaging and genetics. The aim is to develop a multifactorial and explanatory model which helps to improve the quality of existing therapeutic approaches and prevention strategies. At present, parts of the research are funded by the federal states. The authors of this article, supported by scientific associations, have established a research platform called 'pathological gambling' in which research methods and strategies will be discussed which facilitate the implementation of different studies on pathological gambling.

  8. Allostasis as a conceptual framework linking Bipolar Disorder and Addiction

    Mauro ePettorruso

    2014-12-01

    Full Text Available Bipolar disorders and addictions constitute reciprocal risk factors and are best considered under a unitary perspective. The concepts of allostasis and allostatic load may contribute to the understanding of the complex relationships between bipolar disorder and addictive behaviors. Allostasis entails the safeguarding of reward function stability by recruitment of changes in the reward and stress system neurocircuitry and it may help to elucidate neurobiological underpinnings of vulnerability to addiction in bipolar patients. Conceptualizing bipolar disorder as an illness involving the cumulative build-up of allostatic states, we hypothesize a progressive dysregulation of reward circuits clinically expressed as negative affective states (i.e. anhedonia. Such negative affective states may render bipolar disorder patients more vulnerable to drug addiction, fostering a very rapid transition from occasional drug use to addiction, through mechanisms of negative reinforcement. The resulting addictive behavior-related allostatic loads, in turn, may contribute to illness progression. This framework could have a heuristic value to enhance research on pathophysiology and treatment of bipolar disorder and addiction comorbidity.

    2016-06-01

    Background and aims This study focuses on the use of popular information and communication technologies (ICTs) by adolescents: the Internet, mobile phones, and video games. The relationship of ICT use and experiential avoidance (EA), a construct that has emerged as underlying and transdiagnostic to a wide variety of psychological problems, including behavioral addictions, is examined. EA refers to a self-regulatory strategy involving efforts to control or escape from negative stimuli such as thoughts, feelings, or sensations that generate strong distress. This strategy, which may be adaptive in the short term, is problematic if it becomes an inflexible pattern. Thus, the aim of this study was to explore whether EA patterns were associated with addictive or problematic use of ICT in adolescents. Methods A total of 317 students of the Spanish southeast between 12 and 18 years old were recruited to complete a questionnaire that included questions about general use of each ICTs, an experiential avoidance questionnaire, a brief inventory of the Big Five personality traits, and specific questionnaires on problematic use of the Internet, mobile phones, and video games. Results Correlation analysis and linear regression showed that EA largely explained results regarding the addictive use of the Internet, mobile phones, and video games, but not in the same way. As regards gender, boys showed a more problematic use of video games than girls. Concerning personality factors, conscientiousness was related to all addictive behaviors. Discussion and conclusions We conclude that EA is an important construct that should be considered in future models that attempt to explain addictive behaviors. PMID:27363463

    2016-06-01

    Background Sex addiction is a disorder that can have serious adverse functional consequences. Treatment effectiveness research for sex addiction is currently underdeveloped, and interventions are generally based on the guidelines for treating other behavioral (as well as chemical) addictions. Consequently, there is a need to clinically evaluate tailored treatments that target the specific symptoms of sex addiction. It has been proposed that second-generation mindfulness-based interventions (SG-MBIs) may be an appropriate treatment for sex addiction because in addition to helping individuals increase perceptual distance from craving for desired objects and experiences, some SG-MBIs specifically contain meditations intended to undermine attachment to sex and/or the human body. The current study conducts the first clinical investigation into the utility of mindfulness for treating sex addiction. Case presentation An in-depth clinical case study was conducted involving an adult male suffering from sex addiction that underwent treatment utilizing an SG-MBI known as Meditation Awareness Training (MAT). Following completion of MAT, the participant demonstrated clinically significant improvements in addictive sexual behavior, as well as reductions in depression and psychological distress. The MAT intervention also led to improvements in sleep quality, job satisfaction, and non-attachment to self and experiences. Salutary outcomes were maintained at 6-month follow-up. Discussion and conclusion The current study extends the literature exploring the applications of mindfulness for treating behavioral addiction, and findings indicate that further clinical investigation into the role of mindfulness for treating sex addiction is warranted.

  13. Cyber addictions: toward a psychosocial perspective.

    The concept of cyberaddiction is far from being unanimously accepted by scientists (Ko, Yen, Yen, Chen, & Chen 2012; Pezoa-Jares, Espinoza-Luna & Vasquez-Medina 2012; Nadeau et al., 2011; Perraton, Fusaro & Bonenfant 2011). The same is true of addiction to videogames (Hellman, Schoenmakers, Nordstrom, & Van Holst 2013; Coulombe 2010); or to Facebook (Andreassen et al., 2012; Levard & Soulas, 2010). While certain researchers wished to see this condition included in the DSM-5 (Block, 2008), others question the operational and practical bases for the diagnostic criteria. Some see cyberaddiction as a problem linked more to time management, to brain deficits, to an impulse-control disorder or to psychosocial conditions while others consider it to be a pre-existing comorbidity. Considering that most addiction problems are generally understood more as individual and pathological problems rather than the result of psychosocial conditions (poverty, unemployment, weak social ties, social exclusion, hyper individualism, etc), the aim of this article is to propose a psychosocial perspective for this emerging trend in cyberaddictions. To what extent social conditions and cyberaddiction behaviors constitute a potential pathology? Can we include a psychosocial approach to gain a more general picture of this contemporary issue? In response to these questions, a contextualization and an attempt to define cyberaddiction will be followed by an analysis of some major issues in the development of this type of addiction. A demonstration of the cycle of addiction on how people develop addictions, including cyberaddictions, will be done within a psychosocial perspective in order to seize the multifactorial aspects of this addiction.

This recognition is corroborated by inquiries into the neurobiological correlates of addiction, which has indicated that different manifestations of addictive pathology share common neural mechanisms. This review of the literature will explore the feasibility of the somatic marker hypothesis as a unifying explanatory framework of the decision-making deficits that are believed to be involved in addiction development and maintenance. The somatic marker hypothesis provides a neuroanatomical and cognitive framework of decision making, which posits that decisional processes are biased toward long-term prospects by emotional marker signals engendered by a neuronal architecture comprising both cortical and subcortical circuits. Addicts display markedly impulsive and compulsive behavioral patterns that might be understood as manifestations of decision-making processes that fail to take into account the long-term consequences of actions. Evidence demonstrates that substance dependence, pathological gambling, and Internet addiction are characterized by structural and functional abnormalities in neural regions, as outlined by the somatic marker hypothesis. Furthermore, both substance dependents and behavioral addicts show similar impairments on a measure of decision making that is sensitive to somatic marker functioning. The decision-making deficits that characterize addiction might exist a priori to addiction development; however, they may be worsened by ingestion of substances with

    There is a growing view that certain foods, particularly those high in refined sugars and fats, are addictive and that some forms of obesity can usefully be treated as a food addiction. This perspective is supported by a growing body of neuroscience research demonstrating that the chronic consumption of energy-dense foods causes changes in the brain's reward pathway that are central to the development and maintenance of drug addiction. Obese and overweight individuals also display patterns of eating behavior that resemble the ways in which addicted individuals consume drugs. We critically review the evidence that some forms of obesity or overeating could be considered a food addiction and argue that the use of food addiction as a diagnostic category is premature. We also examine some of the potential positive and negative clinical, social, and public policy implications of describing obesity as a food addiction that require further investigation.

OBJECTIVES: to assess 1 the prevalence of 'food addiction' in the Newfoundland population; 2 if clinical symptom counts of 'food addiction' were significantly correlated with the body composition measurements; 3 if food addicts were significantly more obese than controls, and 4 if macronutrient intakes are associated with 'food addiction'. DESIGN: A total of 652 adults (415 women, 237 men recruited from the general population participated in this study. Obesity was evaluated by Body Mass Index (BMI and Body Fat percentage measured by dual-energy X-ray absorptiometry. 'Food addiction' was assessed using the Yale Food Addiction Scale and macronutrient intake was determined from the Willet Food Frequency Questionnaire. RESULTS: The prevalence of 'food addiction' was 5.4% (6.7% in females and 3.0% in males and increased with obesity status. The clinical symptom counts of 'food addiction' were positively correlated with all body composition measurements across the entire sample (p<0.001. Obesity measurements were significantly higher in food addicts than controls; Food addicts were 11.7 (kg heavier, 4.6 BMI units higher, and had 8.2% more body fat and 8.5% more trunk fat. Furthermore, food addicts consumed more calories from fat and protein compared with controls. CONCLUSION: Our results demonstrated that 'food addiction' contributes to severity of obesity and body composition measurements from normal weight to obese individuals in the general population with higher rate in women as compared to men.

    Previous research has found similarities between addiction to psychoactive substances and excessive food consumption. Further exploration is needed to evaluate the concept of "food addiction," as there is currently a lack of psychometrically validated measurement tools in this area. The current study represents a preliminary exploration of the Yale Food Addiction Scale (YFAS), designed to identify those exhibiting signs of addiction towards certain types of foods (e.g., high fat and high sugar). Survey data were collected from 353 respondents from a stratified random sample of young adults. In addition to the YFAS, the survey assessed eating pathology, alcohol consumption and other health behaviors. The YFAS exhibited adequate internal reliability, and showed good convergent validity with measures of similar constructs and good discriminant validity relative to related but dissimilar constructs. Additionally, the YFAS predicted binge-eating behavior above and beyond existing measures of eating pathology, demonstrating incremental validity. The YFAS is a sound tool for identifying eating patterns that are similar to behaviors seen in classic areas of addiction. Further evaluation of the scale is needed, especially due to a low response rate of 24.5% and a non-clinical sample, but confirmation of the reliability and validity of the scale has the potential to facilitate empirical research on the concept of "food addiction".

    Full Text Available In the past decade, research has accumulated suggesting that excessive Internet use can lead to the development of a behavioral addiction. Internet addiction has been considered as a serious threat to mental health and the excessive use of the Internet has been linked to a variety of negative psychosocial consequences. The aim of this review is to identify all empirical studies to date that used neuroimaging techniques to shed light upon the emerging mental health problem of Internet and gaming addiction from a neuroscientific perspective. Neuroimaging studies offer an advantage over traditional survey and behavioral research because with this method, it is possible to distinguish particular brain areas that are involved in the development and maintenance of addiction. A systematic literature search was conducted, identifying 18 studies. These studies provide compelling evidence for the similarities between different types of addictions, notably substance-related addictions and Internet and gaming addiction, on a variety of levels. On the molecular level, Internet addiction is characterized by an overall reward deficiency that entails decreased dopaminergic activity. On the level of neural circuitry, Internet and gaming addiction led to neuroadaptation and structural changes that occur as a consequence of prolonged increased activity in brain areas associated with addiction. On a behavioral level, Internet and gaming addicts appear to be constricted with regards to their cognitive functioning in various domains. The paper shows that understanding the neuronal correlates associated with the development of Internet and gaming addiction will promote future research and will pave the way for the development of addiction treatment approaches.

    2016-03-01

    Scientific interest in "food addiction" is growing, but the topic remains controversial. One critique of "food addiction" is its high degree of phenotypic overlap with binge eating disorder (BED). In order to examine associations between problematic eating behaviors, such as binge eating and "food addiction," we propose the need to move past examining similarities and differences in symptomology. Instead, focusing on relevant mechanisms may more effectively determine whether "food addiction" contributes to disordered eating behavior for some individuals. This paper reviews the evidence for mechanisms that are shared (i.e., reward dysfunction, impulsivity) and unique for addiction (i.e., withdrawal, tolerance) and eating disorder (i.e., dietary restraint, shape/weight concern) frameworks. This review will provide a guiding framework to outline future areas of research needed to evaluate the validity of the "food addiction" model and to understand its potential contribution to disordered eating.

    Addictive disorders are very common and have devastating individual and social consequences. Currently available treatment is moderately effective at best. After many years of neglect, there is renewed interest in potential clinical uses for classic hallucinogens in the treatment of addictions and other behavioral health conditions. In this paper we provide a comprehensive review of both historical and recent clinical research on the use of classic hallucinogens in the treatment of addiction, selectively review other relevant research concerning hallucinogens, and suggest directions for future research. Clinical trial data are very limited except for the use of LSD in the treatment of alcoholism, where a meta-analysis of controlled trials has demonstrated a consistent and clinically significant beneficial effect of high-dose LSD. Recent pilot studies of psilocybin-assisted treatment of nicotine and alcohol dependence had strikingly positive outcomes, but controlled trials will be necessary to evaluate the efficacy of these treatments. Although plausible biological mechanisms have been proposed, currently the strongest evidence is for the role of mystical or other meaningful experiences as mediators of therapeutic effects. Classic hallucinogens have an excellent record of safety in the context of clinical research. Given our limited understanding of the clinically relevant effects of classic hallucinogens, there is a wealth of opportunities for research that could contribute important new knowledge and potentially lead to valuable new treatments for addiction.

    Acute and chronic stress–related mechanisms play an important role in the development of addiction and its chronic, relapsing nature. Multisystem adaptations in brain, body, behavioral, and social function may contribute to a dysregulated physiological state that is maintained beyond the homeostatic range. In addition, chronic abuse of substances leads to an altered set point across multiple systems. Resilience can be defined as the absence of psychopathology despite exposure to high stress a...

    Compulsive behaviors are driven by repetitive urges and typically involve the experience of limited voluntary control over these urges, a diminished ability to delay or inhibit these behaviors, and a tendency to perform repetitive acts in a habitual or stereotyped manner. Compulsivity is not only a central characteristic of obsessive-compulsive disorder (OCD) but is also crucial to addiction. Based on this analogy, OCD has been proposed to be part of the concept of behavioral addiction along with other non-drug-related disorders that share compulsivity, such as pathological gambling, skin-picking, trichotillomania and compulsive eating. In this review, we investigate the neurobiological overlap between compulsivity in substance-use disorders, OCD and behavioral addictions as a validation for the construct of compulsivity that could be adopted in the Research Domain Criteria (RDoC). The reviewed data suggest that compulsivity in OCD and addictions is related to impaired reward and punishment processing with attenuated dopamine release in the ventral striatum, negative reinforcement in limbic systems, cognitive and behavioral inflexibility with diminished serotonergic prefrontal control, and habitual responding with imbalances between ventral and dorsal frontostriatal recruitment. Frontostriatal abnormalities of compulsivity are promising targets for neuromodulation and other interventions for OCD and addictions. We conclude that compulsivity encompasses many of the RDoC constructs in a trans-diagnostic fashion with a common brain circuit dysfunction that can help identifying appropriate prevention and treatment targets.

    Full Text Available With the introduction of new technologies, computer and internet use have become an unavoidable necessity in our daily lives. Internet was originally designed to facilitate communication and research. However the dramatic increase in use of internet in recent years has led to its pathologic use. Turkey, as a developing country with an increasing rate of internet access and computer use is at high risk for this disorder. In our country, this disorder is especially seen in young people who are more skilled in internet and computer use. And because their excessive internet use has led to negative consequences in their academic, social and family lives, patients and their families began search of treatment for this disorder. So clinicians must be aware of this newly emerging disorder and they should be able to apply the appropriate therapeutic interventions. This paper aims to summarize the pharmacological and cognitive-behavioral treatment of internet addiction.

    2015-01-01

    Although most people consider gambling as a recreational activity, some individuals lose control over their behavior and enter a spiral of compulsive gambling leading to dramatic consequences. In its most severe form, pathological gambling is considered a behavioral addiction sharing many similarities with substance addiction. A number of neurobiological hypotheses have been investigated in the past ten years, relying mostly on neuroimaging techniques. Similarly to substance addiction, a number of observations indicate a central role for dopamine in pathological gambling. However, the underlying mechanism seems partly different and is still poorly understood. Neuropsychological studies have shown decision-making and behavioral inhibition deficits in pathological gamblers, likely reflecting frontal lobe dysfunction. Finally, functional MRI studies have revealed abnormal reactivity within the brain reward system, including the striatum and ventro-medial prefrontal cortex. These regions are over-activated by gambling cues, and under-activated by monetary gains. However, the scarcity and heterogeneity of brain imaging studies currently hinder the development of a coherent neurobiological model of pathological gambling. Further replications of results and diversification of approaches will be needed in the coming years in order to strengthen our current model. PMID:26340839

Noncoding RNAs are key regulators of almost all aspects of cellular physiology. MicroRNAs (miRNAs are small (~21–23 nucleotides noncoding RNA transcripts that regulate gene expression at the post-transcriptional level. Recently, microRNAs were shown to play key roles in the drug-induced remodeling of brain reward systems that likely drives the emergence of addiction. Here, we review evidence suggesting that one particular miRNA, miR-212, plays a particularly prominent role in vulnerability to cocaine addiction. We review evidence showing that miR-212 expression is increased in the dorsal striatum of rats that show compulsive-like cocaine-taking behaviors. Increases in miR-212 expression appear to protect against cocaine addiction, as virus-mediated striatal miR-212 over-expression decreases cocaine consumption in rats. Conversely, disruption of striatal miR-212 signaling using an antisense oligonucleotide increases cocaine intake. We also review data that identify two mechanisms by which miR-212 may regulate cocaine intake. First, miR-212 has been shown to amplify striatal CREB signaling through a mechanism involving activation of Raf1 kinase. Second, miR-212 was also shown to regulate cocaine intake by repressing striatal expression of methyl CpG binding protein 2 (MeCP2, consequently decreasing protein levels of brain-derived neurotrophic factor (BDNF. The concerted actions of miR-212 on striatal CREB and MeCP2/BDNF activity greatly attenuate the motivational effects of cocaine. These findings highlight the unique role for miRNAs in simultaneously controlling multiple signaling cascades implicated in addiction.

    Overeating in industrial societies is a significant problem, linked to an increasing incidence of overweight and obesity, and the resultant adverse health consequences. We advance the hypothesis that a possible explanation for overeating is that processed foods with high concentrations of sugar and other refined sweeteners, refined carbohydrates, fat, salt, and caffeine are addictive substances. Therefore, many people lose control over their ability to regulate their consumption of such foods. The loss of control over these foods could account for the global epidemic of obesity and other metabolic disorders. We assert that overeating can be described as an addiction to refined foods that conforms to the DSM-IV criteria for substance use disorders. To examine the hypothesis, we relied on experience with self-identified refined foods addicts, as well as critical reading of the literature on obesity, eating behavior, and drug addiction. Reports by self-identified food addicts illustrate behaviors that conform to the 7 DSM-IV criteria for substance use disorders. The literature also supports use of the DSM-IV criteria to describe overeating as a substance use disorder. The observational and empirical data strengthen the hypothesis that certain refined food consumption behaviors meet the criteria for substance use disorders, not unlike tobacco and alcohol. This hypothesis could lead to a new diagnostic category, as well as therapeutic approaches to changing overeating behaviors. PMID:19223127

  2. Withdrawal: Expanding a Key Addiction Construct.

    Science.gov (United States)

    Piper, Megan E

    2015-12-01

    Withdrawal is an essential component of classical addiction theory; it is a vital manifestation of dependence and motivates relapse. However, the traditional conceptualization of withdrawal as a cohesive collection of symptoms that emerge during drug deprivation and decline with either the passage of time or reinstatement of drug use, may be inadequate to explain scientific findings or fit with modern theories of addiction. This article expands the current understanding of tobacco withdrawal by examining: (1) withdrawal variability; (2) underlying causes of withdrawal variability, including biological and person factors, environmental influences, and the influence of highly routinized behavioral patterns; (3) new withdrawal symptoms that allow for enhanced characterization of the withdrawal experience; and (4) withdrawal-related cognitive processes. These topics provide guidance regarding the optimal assessment of withdrawal and illustrate the potential impact modern withdrawal conceptualization and assessment could have on identifying treatment targets.

  3. Disruption of maternal parenting circuitry by addictive process: rewiring of reward and stress systems

    Directory of Open Access Journals (Sweden)

    2011-07-01

    Full Text Available Addiction represents a complex interaction between the reward and stress neural circuits, with increasing drug use reflecting a shift from positive reinforcement to negative reinforcement mechanisms in sustaining drug dependence. Preclinical studies have indicated the involvement of regions within the extended amygdala as subserving this transition, especially under stressful conditions. In the addictive situation, the reward system serves to maintain habitual behaviors that are associated with the relief of negative affect, at the cost of attenuating the salience of other rewards. Therefore, addiction reflects the dysregulation between core reward systems, including the prefrontal cortex (PFC, ventral tegmental area (VTA, and nucleus accumbens (NAc, as well as the hypothalamic-pituitary-adrenal axis and extended amygdala of the stress system. Here, we consider the consequences of changes in neural function during or following addiction on parenting, an inherently rewarding process that may be disrupted by addiction. Specifically, we outline the preclinical and human studies that support the dysregulation of reward and stress systems by addiction and the contribution of these systems to parenting. Increasing evidence suggests an important role for the hypothalamus, PFC, VTA, and NAc in parenting, with these same regions being those dysregulated in addiction. Moreover, in addicted adults, we propose that parenting cues trigger stress reactivity rather than reward salience, and this may heighten negative affect states, eliciting both addictive behaviors and the potential for parental neglect and abuse.

  5. Deficient plasticity in the hippocampus and the spiral of addiction: focus on adult neurogenesis.

    2013-01-01

    Addiction is a complex neuropsychiatric disorder which causes disruption at multiple levels, including cognitive, emotional, and behavioral domains. Traditional biological theories of addiction have focused on the mesolimbic dopamine pathway and the nucleus accumbens as anatomical substrates mediating addictive-like behaviors. More recently, we have begun to recognize the engagement and dynamic influence of a much broader circuitry which encompasses the frontal cortex, the amygdala, and the hippocampus. In particular, neurogenesis in the adult hippocampus has become a major focus of attention due to its ability to influence memory, motivation, and affect, all of which are disrupted in addiction. First, I summarize toxicological data that reveal strongly suppressive effects of drug exposure on adult hippocampal neurogenesis. Then, I discuss the impact of deficient neurogenesis on learning and memory function, stress responsiveness and affective behavior, as they relate to addiction. Finally, I examine recent behavioral observations that implicate neurogenesis in the adult hippocampus in the emergence and maintenance of addictive behavior. The evidence reviewed here suggests that deficient neurogenesis is associated with several components of the downward spiraling loop that characterizes addiction, including elevated sensitivity to drug-induced reward and reinforcement, enhanced neurohormonal responsiveness, emergence of a negative affective state, memory impairment, and inflexible behavior.

    During last 20 years, neuroimaging with functional magnetic resonance imaging (fMRI) in people with drug addictions has introduced a wide range of quantitative biomarkers from brain's regional or network level activities during different cognitive functions. These quantitative biomarkers could be potentially used for assessment, planning, prediction, and monitoring for "addiction medicine" during screening, acute intoxication, admission to a program, completion of an acute program, admission to a long-term program, and postgraduation follow-up. In this chapter, we have briefly reviewed main neurocognitive targets for fMRI studies associated with addictive behaviors, main study types using fMRI among drug dependents, and potential applications for fMRI in addiction medicine. Main challenges and limitations for extending fMRI studies and evidences aiming at clinical applications in addiction medicine are also discussed. There is still a significant gap between available evidences from group-based fMRI studies and personalized decisions during daily practices in addiction medicine. It will be important to fill this gap with large-scale clinical trials and longitudinal studies using fMRI measures with a well-defined strategic plan for the future. PMID:26822357

    The comorbidity of depression and cocaine addiction suggests shared mechanisms and anatomical pathways. Specifically, the limbic structures, such as the nucleus accumbens (NAc), play a crucial role in both disorders. P11 (S100A10) is a promising target for manipulating depression and addiction in mice. We summarized the recent genetic and viral strategies used to determine how the titration of p11 levels within the NAc affects hedonic behavior and cocaine reward learning in mice. In particular, p11 in the ChAT+ cells or DRD1+ MSN of the NAc, controls depressive-like behavior or cocaine reward, respectively. Treatments to counter maladaptation of p11 levels in the NAc could provide novel therapeutic opportunities for depression and cocaine addiction in humans. PMID:26059306

    Drugs of abuse can "hijack" synaptic plasticity, a physiological basis of learning and memory, establishing maladaptations that can promote drug addiction. A wealth of data supports the existence and importance of neuroadaptations in excitatory neurotransmission upon drug exposure. Recent discoveries, however, have shown that inhibitory neurotransmission mediated by G protein-gated inwardly rectifying potassium (K(+)) (GIRK/Kir3) channels is also subject to adaptation triggered by exposure to drugs of abuse. GIRK channels are expressed in neuronal populations relevant to reward and reward-related behaviors, where their activation by neurotransmitters such as GABA, dopamine, and adenosine reduces neuronal excitability. Studies in animal models have implicated GIRK channels in a number of behaviors including reward. Drugs of abuse also affect the inhibitory neurotransmission mediated by GIRK channels. These changes might be important for the development, maintenance, or relapse of addiction, making GIRK channels promising targets for novel addiction therapies. PMID:26422986

  15. Addiction and dependence in DSM-V.

    Science.gov (United States)

    O'Brien, Charles

    2011-05-01

    As preparations for the fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM) are under way, this paper focuses upon changes proposed for the substance use disorders section. It briefly outlines the history behind the current nomenclature, and the selection of the term 'dependence' over 'addiction' in earlier versions of the DSM. The term 'dependence', while used in past decades to refer to uncontrolled drug-seeking behavior, has an alternative meaning--the physiological adaptation that occurs when medications acting on the central nervous system are ingested with rebound when the medication is abruptly discontinued. These dual meanings have led to confusion and may have propagated current clinical practices related to under-treatment of pain, as physicians fear creating an 'addiction' by prescribing opioids. In part to address this problem, a change proposed for DSM-V is to alter the chapter name to 'Addiction and Related Disorders', which will include disordered gambling. The specific substance use disorders may be referred to as 'alcohol use' or 'opioid use' disorders. The criteria for the disorders are likely to remain similar, with the exception of removal of the 'committing illegal acts' criterion and addition of a 'craving' criterion. The other major change relates to the elimination of the abuse/dependence dichotomy, given the lack of data supporting an intermediate stage. These changes are anticipated to improve clarification and diagnosis and treatment of substance use and related disorders.

    Full Text Available This work was a part of a broader empirical study of Internet users with excessive and dysfunctional Internet use symptoms. The aim of this particular article was to describe user profiles of Internet addicts in Serbia. The study recruited 100 subjects in total, 50 in both the clinical and control group. The clinical group included the Internet users who asked for professional help due to the symptoms of the excessive Internet use and fulfilled the diagnostic criteria for Internet behavior disorder proposed by the American Psychology Association. The results have shown that population with Internet addiction symptoms equally included both males and females, mostly adolescent and younger population, teenagers and university students, persons with higher income and users from economically more developed areas of Serbia. The user profile of this group is characterized by frequent logging on with intervals of several hours online at one time, mainly in the evening or at night, and also intensive negative reactions to any form of Internet access deprivation. By means of factor analysis, three dimensions of pathological use have been established: mixed type with particular need for up-to-date information, social interaction addiction and need for fun-seeking, namely pursuing hobbies online (cyberpornography, online games, music, art and so on.

    A survey of 80 opiate addicts included in a detoxification program was conducted at the Institute on Addictions in Belgrade. In addition to a dependence diagnosis and mental disorders based on DSM-III-R, we applied a Tridimensional Personality Questionnaire (TPQ) that measures the 3 major personality dimensions: novelty-seeking (NS), harm avoidance (HA) and reward dependence (RD). When compared with a control group (a sample of Yugoslav undergraduate students), the opiate addicts demonstrate significantly high NS dimension as well as significant divergences of HA and RD subscales. The surveyed opiate addicts demonstrate a high percentage of personality disorders specifically in cluster B. The personality dimensions of opiate addicts showed certain temperament traits, such as: impulsiveness, shyness with strangers, fear of uncertainty and dependence. NS, HA and RD determined by temperament specifics may be an etiological factor in forming of a personality disorder, an affective disorder as well as of a drug choice.

    Food addiction (FA) is loosely defined as hedonic eating behavior involving the consumption of highly palatable foods (ie, foods high in salt, fat, and sugar) in quantities beyond homeostatic energy requirements. FA shares some common symptomology with other pathological eating disorders, such as binge eating. Current theories suggest that FA shares both behavioral similarities and overlapping neural correlates to other substance addictions. Although preliminary, neuroimaging studies in response to food cues and the consumption of highly palatable food in individuals with FA compared to healthy controls have shown differing activation patterns and connectivity in brain reward circuits including regions such as the striatum, amygdala, orbitofrontal cortex, insula, and nucleus accumbens. Additional effects have been noted in the hypothalamus, a brain area responsible for regulating eating behaviors and peripheral satiety networks. FA is highly impacted by impulsivity and mood. Chronic stress can negatively affect hypothalamic-pituitary-adrenal axis functioning, thus influencing eating behavior and increasing desirability of highly palatable foods. Future work will require clearly defining FA as a distinct diagnosis from other eating disorders. PMID:27503449

    Exercise addiction is characterized by excessive exercise behavior with potential negative consequences. The symptoms consist of salience, mood modification, tolerance, withdrawal symptoms, conflicts, and relapse. The purpose of this study was to test the psychometric properties of the exercise addiction inventory (EAI) and to estimate the prevalence of exercise addiction in a Danish normal weight sport population. A sample of 780 habitual fitness and football exercisers were contacted and 590 completed the EAI and an in-house questionnaire containing questions about variables related to exercise addiction: (a) exercise frequency; (b) continuance despite injuries; and (c) personal perception of addiction. The results demonstrated an overall prevalence of exercise addiction of 5.8%. There was no significant difference between fitness and football prevalences. The internal reliability of EAI was acceptable with a Cronbach's α of 0.66. The criterion validity was tested toward the three variables related to exercise addiction. The dependent group had significantly higher scores on the three variables than the non-dependent group. Exercise addiction seems to exist in both fitness and football. The EAI is a useful screening tool and might be applicable in future screening and prevention of exercise addiction. However, further investigation about the population is needed to understand the phenomenon and to identify the risk group.

    Full Text Available An investigation was carried out on N=234 opioid drug abusers (Nm=170, Nf=64 averaged age of M=25.72 with the aim of determing the average levels for addiction and criminality, and sex and age differences. The Eysenck Personality Questionnaire for Adults that contained Subscales of Addiction and Criminality was used (EPQ R/A, Eysenck & Eysenck, 1991. The average levels were determined: for Addiction scale in male (M=16.57; SD=5.12 and female (M=17.36; MD=4.82, and for Criminality scale in male (M=17.34; SD=5.18 and female (M=18.34; SD=5.17. The correlation analysis showed significant positive correlation between the level of addiction and criminality on whole sample (r=.851, p=.000. Unemployed male and female heroin addicts had significantly higher results on the Addiction scale, and unemployed male addicts on the Criminality scale, too. This last correlation was not established for female addicts, but the another one was: with the higher level of education there was lower possibility of antisocial and criminal behavior in female addicts. The findings were interpreted in the frame of psychosocial factors that were relevant for the treatment.

    Based on Bandura theory of social learning and related theories about effect of peer norms, a cross- sectional study was conducted in Beijing to explore the relationship between Perceived Peers' Internet Overuse Behavior, attitude on Internet Overuse, pressures of Internet using and College students' Internet addiction. 3049 college students from two universities in Beijing city were invited to fulfill the questionnaire about the peers' Internet overuse behaviors, attitude on Internet overuse, pressures when they using Internet and Internet addiction level. Structural equation model were used to explore the affect mechanism of peers' pressures on the relationship between peers' Internet overuse behavior and attitude and Internet addiction. The results showed that: (1) Compared to Internet non-addicts, Internet addicts among college students perceived more Internet overuse behaviors and higher pressure from peers, and more positive attitudes about Internet overuse. (2) College students perceived peers' Internet overuse behaviors and attitude on Internet overuse; pressures of Internet using were positively correlated to Internet addiction. (3) Peers' lnternet overuse behaviors not only have a direct effect on college students' Internet addiction, but also have an indirect effect on Internet addiction through peers' pressure; meanwhile, Peers' attitude on Internet overuse can' t predict college students' Internet addiction directly, but have an indirect effect on Internet addiction through peers' pressure. Conclusion: Peers' pressure play a partial mediation effect on the relationship between Peers' Internet overuse behaviors and college students' Internet addiction level. Meanwhile, peers' pressures play a full mediation effect on the relationship between Peers' attitude on Internet overuse and college students' Internet addiction level.%基于社会学习理论和同伴规范影响理论,通过整群取样的方法从北京市两所高校中共选取3068名大一

    2016-08-01

    Full Text Available Cocaine use leads to health, social and legal problems. The aim of this paper is to discuss cocaine action, addicts characteristics, use patterns and consequences, as well as addiction treatment methods. A literature review was based on the Medline, PubMed, Polish Medical Bibliography databases and the Silesian Library resources. The Police and Central Statistical Office statistics, as well as the World Health Organization, the European Monitoring Centre for Drugs and Drug Addiction and the National Office for Combating Drug Addiction reports were used. Cocaine leads to mood improvement, appetite decrease, physical and intellectual activity enhancement, euphoria, inflated self-esteem, social networking ease and increased sexual desire. Cocaine hydrochloride is mainly used intranasaly, but also as intravenous and subcutaneous injections. Cocaine use and first addiction treatment fall in later age compared to other psychoactive substances. There is a high men to women ratio among addicts. There is a relationship between cocaine addiction, the presence of other disorders and genetic predisposition to addiction development. Polish reports indicate higher popularity of cocaine among people with a high economic and social status. Although Poland is a country with the low percentage of cocaine use, its popularity is growing. The consequences of cocaine use concern somatic and mental health problems, socioeconomic and legal conditions. The drug plays a role in crimes and traffic accidents. Because of the risks associated with cocaine use, it has been listed in a register of drugs attached to the Act on Counteracting Drug Addiction. Addiction treatment includes psychological, pharmacological and harm reduction strategies. Med Pr 2016;67(4:537–544

  11. Intertemporal Bargaining in Addiction

    Directory of Open Access Journals (Sweden)

    George Ainslie

    2013-08-01

    Full Text Available The debate between disease models of addiction and moral or voluntarist models has been endless, and often echoes the equally endless debate between determinism and free will. I suggest here that part of the problem comes from how we picture the function of motivation in self-control. Quantitative experiments in both humans and nonhumans have shown that delayed reward loses its effectiveness in proportion to its delay. The resulting instability of preference is best controlled by a recursive self-prediction process, intertemporal bargaining, which is the likely mechanism of both the strength and the experienced freedom of will. In this model determinism is consistent with more elements of free will than compatibilist philosophers have heretofore proposed, and personal responsibility is an inseparable, functional component of will. Judgments of social responsibility can be described as projections of personal responsibility, but normative responsibility in addiction is elusive.

  12. Addiction as excessive appetite.

    Science.gov (United States)

    Orford, J

    2001-01-01

    The excessive appetite model of addiction is summarized. The paper begins by considering the forms of excessive appetite which a comprehensive model should account for: principally, excessive drinking, smoking, gambling, eating, sex and a diverse range of drugs including at least heroin, cocaine and cannabis. The model rests, therefore, upon a broader concept of what constitutes addiction than the traditional, more restricted, and arguably misleading definition. The core elements of the model include: very skewed consumption distribution curves; restraint, control or deterrence; positive incentive learning mechanisms which highlight varied forms of rapid emotional change as rewards, and wide cue conditioning; complex memory schemata; secondary, acquired emotional regulation cycles, of which 'chasing', 'the abstinence violation effect' and neuroadaptation are examples; and the consequences of conflict. These primary and secondary processes, occurring within diverse sociocultural contexts, are sufficient to account for the development of a strong attachment to an appetitive activity, such that self-control is diminished, and behaviour may appear to be disease-like. Giving up excess is a natural consequence of conflict arising from strong and troublesome appetite. There is much supportive evidence that change occurs outside expert treatment, and that when it occurs within treatment the change processes are more basic and universal than those espoused by fashionable expert theories.

    2014-02-01

    Public knowledge and attitudes about addiction are largely inconsistent with scientific evidence. The gap between the facts and public and professional perceptions is due in part to the language used to describe the disease and those who have it. A key step in modifying public attitudes and improving how health professionals and policymakers address addiction is to better align the language of addiction with the scientific evidence. Unless we clarify the language, those with the disease will continue to experience the stigma associated with it and attempts to deliver comprehensive and effective evidence-based prevention, treatment, and disease management will be profoundly compromised.

    Excessive playing of computer games like some other behaviors could lead to addiction. Addictive behaviors may induce their reinforcing effects through stimulation of the brain dopaminergic mesolimbic pathway. The status of dopamine receptors in the brain may be parallel to their homologous receptors in peripheral blood lymphocytes (PBLs). Here, we have investigated the mRNA expression of dopamine D3, D4 and D5 receptors in PBLs of computer game addicts (n = 20) in comparison to normal subjects (n = 20), using a real-time PCR method. The results showed that the expression level of D3 and D4 dopamine receptors in computer game addicts were not statistically different from the control group. However, the expression of the mRNA of D5 dopamine receptor was significantly down-regulated in PBLs of computer game addicts and reached 0.42 the amount of the control group. It is concluded that unlike with drug addiction, the expression levels of the D3 and D4 dopamine receptors in computer game addicts are not altered compared to the control group. However, reduced level of the D5 dopamine receptor in computer game addicts may serve as a peripheral marker in studies where the confounding effects of abused drugs are unwanted. PMID:25967984

    2013-09-01

    Full Text Available Cannabis is one of the most widely used illicit substance among users of stimulants such as cocaine and amphetamine. Interestingly, recent accumulating evidence points toward the involvement of the endocannabinoid system (ECBS in the neurobiological processes related to stimulant addiction. This article presents an up-to-date review with deep-insights into the pivotal role of the ECBS in the neurobiology of stimulant addiction and the effects of its modulation on addictive behaviors. The aims of this article are to: 1 review the role of cannabis use and ECBS modulation in the neurobiological substrates of psychostimulant addiction and 2 evaluate the potential of cannabinoid-based pharmacological strategies to treat stimulant addiction. A growing number of studies support a critical role of the ECBS and its modulation by synthetic or natural cannabinoid in various neurobiological and behavioral aspects of stimulants addiction. Thus, cannabinoids modulate brain reward systems closely involved in stimulants addiction, and provide further evidence that the cannabinoid system could be explored as a potential drug discovery target for treating addiction across different classes of stimulants.

    This study examined the prevalence of Internet addiction among college students in China and explored the correlations between Internet addiction and psychosocial factors. A total of 1,173 Chinese college students (62.1 percent males, Mage = 19.65 years) were invited to complete a questionnaire containing measures of demographic characteristics, psychosocial correlates, including the quality of the parent-child relationship, propensity for depression, and psychosocial competence, and Internet addictive behaviors. Among the participating students, 15.2 percent were classified as having Internet addiction. Furthermore, students who reported poorer parent-child relationships, higher levels of depression, and lower levels of psychosocial competence were more likely to report behaviors indicative of Internet addiction. Internet addiction was prevalent among college students in China. The significant predictors of Internet addiction were found to include the quality of the family environment (i.e., the quality of the parent-child relationship), personal mental health status (i.e., the existence of depression), and the level of developmental assets (i.e., psychosocial competence). These findings suggest that improving the quality of family life and promoting psychosocial competence among youth can be promising approaches for preventing or/and reducing Internet addiction among college students in China.

    Roth, K

    1992-03-01

    DSM-III-R names sexual addiction for the first time as a sexual disorder. In this study a group of alcoholics was examined who described their own sexual behavior as being addictive and self-destructive. In this nearly all male patient group sexual addiction manifested itself mostly in excessive masturbation and obsessional sexual fantasies often in combination with use of pornography. Promiscuity, prostitute contacts and excessive sexual demands on a steady partner and sexually deviant behavior, were less often reported in this population. The addictive sexual behavior was said to be usually provoked by emotional distress and unresolved conflicts. More than 80% of these patients were dependent upon at least one other substance beside alcohol. Two-thirds considered their sexual addictive behavior to be their primary and earliest dependency. The nosology of this disorder seems to be unspecific, since a number of forms of neurosis and personality disorder are diagnosed. A psychodynamic interpretation of sexual addiction points to defence mechanisms against inner psychic conflicts, as seen both in addiction and sexual perversion. Aspects of differential diagnosis and classification are also discussed. PMID:1579173
