Radiation and mental retardation

International Nuclear Information System (INIS)

Pochin, E.E.

1988-01-01

A brief article discusses mental retardation in children who had been exposed to ionizing radiation in utero. The time of greatest sensitivity is between the 8th and 15th week after conception and the time of lesser sensitivity between the 16th and 25th weeks. An examination of the thresholds for exposure indicate that severe mental retardation would not result from any present environmental exposures of the public. (U.K.)

CASE REPORT OF A MENTALLY RETARDED CHILD

Full Text Available Mental retardation is a complex individual and social problem. According to WHO, around 1-3 % of world population are mentally retarded people and the percentage between school children is around 2 %.The development of a mentally retarded child depends on factors related to the disability itself, all the limitations and characteristics which results from that. But, physical, psychical, educational and social development of a mentally retarded child, also, depend on other conditions, such as the family and the wider environment, their reactions, attitudes, awareness and sensitivity for special needs of the child, as well as their preparedness and possibilities to respond.At the same time, it is necessary that the mentally retarded child is detected and diagnosed in time, as well as the early start of an adequate treatment.

Intrauterine radiation exposures and mental retardation

International Nuclear Information System (INIS)

Miller, R.W.

1988-01-01

Small head size and mental retardation have been known as effects of intrauterine exposure to ionizing radiation since the 1920s. In the 1950s, studies of Japanese atomic-bomb survivors revealed that at 4-17 wk of gestation, the greater the dose, the smaller the brain (and head size), and that beginning at 0.5 Gy (50 rad) in Hiroshima, mental retardation increased in frequency with increasing dose. No other excess of birth defects was observed. Otake and Schull (1984) pointed out that the period of susceptibility to mental retardation coincided with that for proliferation and migration of neuronal elements from near the cerebral ventricles to the cortex. Mental retardation could be the result of interference with this process. Their analysis indicated that exposures at 8-15 wk to 0.01-0.02 Gy (1-2 rad) doubled the frequency of severe mental retardation. This estimate was based on small numbers of mentally retarded atomic-bomb survivors. Although nuclear accidents have occurred recently, new cases will hopefully be too rare to provide further information about the risk of mental retardation. It may be possible, however, to learn about lesser impairment. New psychometric tests may be helpful in detecting subtle deficits in intelligence or neurodevelopmental function. One such test is PEERAMID, which is being used in schools to identify learning disabilities due, for example, to deficits in attention, short- or long-term memory, or in sequencing information. This and other tests could be applied in evaluating survivors of intrauterine exposure to various doses of ionizing radiation. The results could change our understanding of the safety of low-dose exposures

Recessive VARS2 mutation underlies a novel syndrome with epilepsy, mental retardation, short stature, growth hormone deficiency, and hypogonadism

Most mitochondrial and cytoplasmic aminoacyl-tRNA synthetases (aaRSs) are encoded by nuclear genes. Syndromic disorders resulting from mutation of aaRSs genes display significant phenotypic heterogeneity. We expand aaRSs-related phenotypes through characterization of the clinical and molecular basis of a novel autosomal-recessive syndrome manifesting severe mental retardation, ataxia, speech impairment, epilepsy, short stature, microcephaly, hypogonadism, and growth hormone deficiency.A G>A variant in exon 29 of VARS2 (c.3650G>A) (NM_006295) was identified in the index case. This homozygous variant was confirmed by Sanger sequencing and segregated with disease in the family studied. The c.3650G>A change results in alteration of arginine to histidine at residue 1217 (R1217H) of the mature protein and is predicted to be pathogenic.These findings contribute to a growing list of aaRSs disorders, broadens the spectrum of phenotypes attributable to VARS2 mutations, and provides new insight into genotype-phenotype correlations among the mitochondrial synthetase genes.

Mental Retardation, Poverty and Community Based Rehabilitation

2009-10-01

Full Text Available A person with moderate mental retardation would, in a western country, be "diagnosed" early on in life. Consequently, such a child is likely to be sent for special education. Given the high level of job requirements, such a person is unlikely to be employed in the open market later in life. Mental retardation is one of the most frequent disabilities in most studies, mental retardation is found in about three percent of the population. Persons even with mild mental retardation have very large difficulties finding employment and are for this reason often deprived of opportunities for suitable and productive income generation this is why most stay poor. But disability does not only cause poverty poverty itself causes disability. This study follows an analysis, based on a review of the Swedish programme for mental retardation during the period 1930-2000. It is concluded that in Sweden a very large proportion of mild and moderate mental retardation has been eliminated though the combination of poverty alleviation with a community-based rehabilitation programme. For these situations a pro-active programme analysing and meeting the needs of the target groups should be useful as a means to achieve poverty alleviation.

Full Text Available Introduction: Mental retardation is one of the most important problems of general health. The purpose of this study was to evaluate inheritance pattern of mentally retarded patients in Yazd city. Methods: In a descriptive cross- sectional study, all medical records and pedigrees of 320 mentally retarded children whose parents had referred for genetic consultation to the Welfare center of Yazd city were reviewed. Results: Of the total, 62.8% of the parents had consanguineous marriage. Mean inbreeding coefficient of offsprings was 0.0713 in third degree related parents versus 0.0156 in non-related parents. Mental retardation was seen in 43.4% of first– degree relatives of children (6.6% of parents and 36.8% of siblings, respectively. Frequency of mental retardation did not differ significantly in both sexes. Pedigree showed inheritance pattern in 43.4% of patients (autosomal recessive, autosomal dominant and x-linked inheritance pattern were seen in 33.75%, 6.9% and 2.8%, respectively, while 37% of patients had no definite inheritance pattern. Abnormal karyotype were seen in 19.4% of patients, 28 of whom(8.75% of all patients had Down syndrome. The prevalence of autosomal recessive inheritance in patients with consanguineous marriages and non family marriages was 62.8 % and 10%, respectively (P=0. 002. Conclusion: Since multiple cases of mental retardation were seen in families and rate of consanguineous marriage was more in parents of mentally retarded children, genetic counseling in consanguinity marriages and families of mentally retarded children can prevent incidence of mental retardation in these families.

Full Text Available The paper presents the study of the association between sleep disturbances and mental retardation in children. Attention is paid to the instant connection between sleep neurophysiology and intellectual progress, as well as between sleep disorders and the pathogenesis of mental retardation in children. The data on characteristic forms of sleep disturbances, including bed-time resistance, frequent night awakenings, parasomnias, abnormal sleep structure, and notably reduced REM-sleep proportion are provided. The potential role of abnormal melatonin production in the origins of sleep disturbances in children with mental retardation is discussed. Certain approaches to pharmacological and non-pharmacological corrections of sleep disorders are outlined.

Kernan, K T; Sabsay, S

1987-01-01

Referential first mentions in narrative reports of a short film by 40 mildly mentally retarded adults and 20 nonretarded adults were compared. The mentally retarded sample included equal numbers of male and female, and black and white speakers. The mentally retarded speakers made significantly fewer first mentions and significantly more errors in the form of the first mentions than did nonretarded speakers. A pattern of better performance by black males than by other mentally retarded speakers was found. It is suggested that task difficulty and incomplete mastery of the use of definite and indefinite forms for encoding old and new information, rather than some global type of egocentrism, accounted for the poorer performance by mentally retarded speakers.

This research is to investigate the level of mild mental retardation geometry students thinking. This research focuses on the geometry thinking level based on Van Hiele theory. This study uses qualitative methods with case study strategy. Data obtained from observation and tests result. The subjects are 12 mental retardation students. The result show that ability of mild mental retardation students with each other is different but have same level of level thinking geometry. The geometry thinking level of mental retardation students was identified in level 1 of the Van Hiele theory. Based on the level thinking geometry of mental retardation students simplify geometry thinking teachers in selecting appropriate learning methods, choose the materials in accordance with ability, and can modify the material following the geometry thinking level of mental retardation students.

Clustering of inhibitory γ-aminobutyric acidA (GABAA) and glycine receptors at synapses is thought to involve key interactions between the receptors, a “scaffolding” protein known as gephyrin and the RhoGEF collybistin. We report the identification of a balanced chromosomal translocation in a female patient presenting with a disturbed sleep-wake cycle, late-onset epileptic seizures, increased anxiety, aggressive behavior, and mental retardation, but not hyperekplexia. Fine mapping of the breakpoint indicates disruption of the collybistin gene (ARHGEF9) on chromosome Xq11, while the other breakpoint lies in a region of 18q11 that lacks any known or predicted genes. We show that defective collybistin transcripts are synthesized and exons 7–10 are replaced by cryptic exons from chromosomes X and 18. These mRNAs no longer encode the pleckstrin homology (PH) domain of collybistin, which we now show binds phosphatidylinositol-3-phosphate (PI3P/ PtdIns-3-P), a phosphoinositide with an emerging role in membrane trafficking and signal transduction, rather than phosphatidylinositol 3,4,5-trisphosphate (PIP3/PtdIns-3,4,5-P) as previously suggested in the “membrane activation model” of gephyrin clustering. Consistent with this finding, expression of truncated collybistin proteins in cultured neurons interferes with synaptic localization of endogenous gephyrin and GABAA receptors. These results suggest that collybistin has a key role in membrane trafficking of gephyrin and selected GABAA receptor subtypes involved in epilepsy, anxiety, aggression, insomnia, and learning and memory.

The purpose of this research is to find out the problems faced by teachers in teaching materials on mental retardation students. It focused on the difficulties faced by the teacher in teaching geometry. A qualitative method with field study approach used in this study. The subjects in this research are the teacher and mild mental retardation students. There are six teachers and six students involve as the subject which is chosen by purposive sampling. The data of this research is the observation and interview against teachers and mental retardation students. The data was analyzed qualitatively with Miles and Huberman steps. The results of this research show that mental retardation students have less attention to the materials, less special books or learning media props, difficult in the set the students, and the difficulty in choosing the material that suits the student needs and the condition of mental retardation students. There's not much pay attention to the children with special need, particularly mental retardation student. Thus, this study can help analyze the difficulties teachers so that learning math for mental retardation students more optimal.

Several chromosomal syndromes include brain dysfunction symptoms as mental retardation, developmental speech disorders and epilepsy. Authors present a case report of Angelman syndrome – neuro behavioral disorder associated with deletion in the maternal chromosome 15q 11-g13 causing mutation of the UBE3A gene. The main features consist of psychomotor retardation, developmental speech disorder, ataxia, tremor, hyperactivity, clapping hands, inadequate laughter and happiness, attention deficit and epilepsy. The later starts before the 3rd year of age in form of atypical absences, myoclonic and generalized tonic-clonic seizures. EEG typically shows episodes of slow activity with sharp waves occipitally. Prognosis is poor. Genetic syndromes importantly contribute to the etiology of epilepsy with early seizures. (author)

Crusted piloleiomyoma with mental retardation: A rare association

Directory of Open Access Journals (Sweden)

Kamboj Sangeeta

2009-01-01

Full Text Available Piloleiomyoma is an uncommon benign smooth muscle neoplasm arising from arrector pili muscle. It is clinically defined by the presence of solitary or multiple reddish brown, dome-shaped, smooth papules or nodules, ranging in size from a few millimeters to a centimeter. The patients are otherwise healthy; but mental retardation developing in some patients with multiple Piloleiomyomas has been emerging as an intriguing matter for analysis by the scientists. In this case report, a mentally retarded patient with Piloleiomyoma is described, who, besides the characteristic smooth and dome-shaped lesions on the anterolateral aspect of the dorsum of the right foot, had developed crusting on one of the largest lesions. The histopathological features were consistent with Piloleiomyoma. The occurrence of Piloleiomyoma in a mentally retarded child and its unusual crusted nature has been rarely reported. The association between Piloleiomyoma and mental retardation is further stressed in this case report.

Objective To understand the prevalence and rehabilitation status of autism and mental retardation in China. Methods Screening test and clinical assessment were conducted for the diagnosis of autism and mental retardation. The assessment included investigation of the histories of medical conditions and development of these two disorders, utilization and needs for the rehabilitation service, and related intellectual and behavioral appraisal. Results Among the 7345 children investigated, the prevalence of autism disorder was 1.10 cases per 1000 children aged 2-6 years (95% CI=0.34 to 2.54), and the prevalence of mental retardation was 10.76 cases per 1000 children (95% CI=8.40 to 13.12). All the children suffering from autistic disorder were intellectually disabled, whereas 31.0% of the non-autism mental retardates had other disabilities. The medical conditions prior to birth and perinatal period were important potential factors for autism. Half of the autistic children and 84% of the children with non-autism mental retardation had never received any rehabilitative service. Conclusions The prevalence of autistic disorder in children aged 2-6 years in Tianjin is rather high. It is urgent to improve the status of the autistic and intelligently disabled young children in China. In order to upgrade the level of early diagnostic and improve the intervention to autism and mental retardation, public awareness and training courses should be heightened.

Also, it is a starting point in the process of special education and rehabilitation in regards to their removal and mitigation.The structure of the physical deformities among persons with mental retardation were analyzed in terms of age and degree of mental retardation in relation to everyday life activities.The inquiry covered 170 respondents with mental retardation in both sexes. All respondents were placed in an institution for treatment of persons with severe and profound mental retardation (Special Institute Deep River. On the basis of two criteria, participants are divided into groups. The first criterion forestablishing a group of level of mental retardation: Group I - severe mental retardation (TMR and Group II - profound mental retardation (DMR. A second criterion for establishing the age group of respondents: Group I - age 18 years; Group II- Age 19 - 30 years and Group III - over 31 years. The structure of the physical deformities was analyzed in terms of age and degree of mental retardation in relation to activities in everyday life.For the purposes of the planned research , an integral protocol is established for the evaluation of physical deformities among persons with disabilities, including: an application form for general information about the respondents, a questionnaire to assess somatic status, and a clinical sheet and test activities in everyday life (Test ASZH, Rusk, 1971. All data obtained by the research are expressed quantitatively and treated with the following statistical methods and procedures: number of repetitions, frequency and percentages, measure of central tendency, the arithmetic mean and standard deviation, χ2 and Fisher Exact - test

The editorial comments on a report published by the Radiation Effects Research Foundation in Hiroshima updating information on the induction of mental changes in the light of the revised and more detailed estimate of doses of radiation during pregnancies received by those exposed at Hiroshima and Nagasaki. The estimated risks are little changed. The likelihood of a threshold for exposure during the 16th to 25th week is confirmed-at 700 mGy (with a lower 95% confidence interval of 200 mGy). For the more sensitive time between the eighth to 15th weeks a linear model with no threshold still gives a statistically adequate fit to the data. Now, however, if linear models are tested without the constraint of postulating a threshold of zero, fits are obtained indicating substantial thresholds below which mental retardation would not result. When data on all children are included the maximum likelihood threshold value averages about 250 mGy on the different criteria tested (with mean 95% confidence intervals of 0 and 550 mGy). Or if the analyses exclude five children with conditions that themselves sometimes cause mental retardation a threshold of about 400 mGy is indicated (with mean 95% confidence intervals of 150 and 600 mGy).

The percentage of people with mental retardation in the general population is estimated at about 2.3%, with adolescence (15-20 years) constituting the development period during which a peak in rates of mental retardation is observed. The increased prevalence of adolescence may be explained from the fact that the specified requirements of the school initially, and society later, inevitably lead to comparative evaluation of the teen with mental retardation in relation to peers, thus making mental retardation more apparent. Adolescents with mental retardation face a number of physical and psychological needs which are not often distinguishable and as a consequence undergo the deterioration of their already burdened quality of life. In particular, mental health problems occur 3 to 4 times more often in adolescents with mental retardation compared with adolescents of the general population. This review presents the most recent epidemiological findings regarding the correlation between behavioral disorders, substance use and the possible comorbidity in adolescents with intellectual disability, both at community level and residential care level. Epidemiological data indicate that behavioral disorders are among the most common types of psychopathology in mentally retarded adolescents with the severity and symptoms varying depending on the personal characteristics of each adolescent. Regarding substance use, the available data show that the rates of substance use (alcohol, smoking, illicit drugs) are lower in this specific population group but the differences over the last years tend to be eliminated. Finally, according to the few surveys that were examined referring to the comorbidity of behavioral disorders and substance use in adolescents with intellectual disability, the results were contradictory. Specifically, while behavioral disorders continued to be one of the most common types of psychopathology, the related substances disorders indicated lower rates compared to

The study was carried out with the aim of determining the factors affecting and to evaluate anxiety situations and self-esteem of children with and without mentally retarded siblings. The sampling included 227 healthy children: 108 of them have mental retarded sibling and 119 of them do not have mental retarded sibling. The context of this study consisted of 15-18 year of age healthy children with mentally retarded siblings and 15-18 year of aged healthy children having at least one sibling between the dates February 15(st) and June 26(st) 2010. Personal Information Form, Rosenberg Self-Esteem Scale and Trait Anxiety Scale were used. It was found out that trait anxiety of 17-18 aged of children with mental retarded sibling (47.04 ± 7.3) was higher than that of the children without mental retarded siblings (44.05 ± 11.23) (P self-esteem of children with mentally retarded sibling was not affected from the handicap of their siblings (P > 0.05). Trait anxiety score averages of children with mentally retarded sibling and experience some difficulties due to his or her siblings's handicap (47.00 ± 7.76) were found higher than those of those of the children without any problem with the environment (42.61 ± 7.48) (P self-esteem in both groups were not significant different, score of trait anxiety for children with mentally disabled siblings was higher in comparison. It was concluded that anxiety of children with and without mentally retarded siblings increased as self-esteem of these children decreased.

Full Text Available Introdution: Presence of mentally retarded children as a source of pressure can jeopardize the general health of parents, especially mothers. The range of effect depends on the recognitive evaluation and the individual. The aim of this study was to investigate the effect of coping-therapy on mental health of mothers with genetically and non genetically mentally retarded children referring to Yazd clinical center. Methods: This study was semi experimental and included 40 mothers with mentally retarded children studying in schools supported by the welfare organization of Yazd in 2009- 2010 and were selected by available sampling method. They were divided to two groups; case and control. Before any therapy, all of the mothers answered a general health questionnaire(GHQ28. In the next step, coping-therapy was performed on the case group. In the end, all of the mothers answered the same questionnaire(GHQ28 and data were analyzed by covariance method and t test. Results: The research indicated that coping-therapy has a positive effect on the mental health of mothers with genetically mentally retarded children. This effect is similar on mothers of children with non genetically mental retarded children. Coping-therapy decreases the somatic signs of depression in mothers and improves their sleeping and social efficacy. There was no association of age and educational level of mothers with coping-therapy. Conclusion: Coping-therapy can improve the mental health of mothers of both genetically and non genetically mentally retarded children

Full Text Available An important factor of the successful integration of mentally retarded people is the readiness of the society to accept such people as equal members. In this study we tested the hypothesis that the attitude toward mentally retarded people depends on values and moral factors. The sample comprised 169 students of technical college and pedagogical university. The attitude toward mentally retarded people was measured using a modified version of Mental Retardation Attitude Inventory (MRAI-R by Antonak & Harth, values were tested using Portrait Values Questionnaire (PVQ-R2 by Schwartz, and moral foundations were measured using Moral Foundations Questionnaire (MFQ by Graham et al.. We elaborated modified Russian version of MRAI-R, showed its factor structure and good psychometric properties. The main moral factor of the attitude toward mentally retarded people was the importance of fairness: the higher it is the higher is the readiness to diminish the social distance with the mentally retarded. The importance of authority was associated with the low approval of inclusive education for the mentally retarded. The most important predictor of the attitude toward mentally retarded people was gender: girls demonstrated a more positive attitude towards the mentally retarded.

Full Text Available Cognitive and mental disorders often occur in patients with epilepsy and significantly reduce the quality of life of patients and their families. Approximately in 35 % of patients, despite treatment, various violations of intelligence, behavior, affective sphere of different degree of seve rity are preserved. In general, mental (affective, anxious and psychotic disorders occur in epilepsy 2–3 times more often than in the general population. The most common is depression: the occurrence of depression and anxiety in epilepsy varies from 20 to 55 % (and more than 50 % of patients with refractory focal epilepsy, especially epilepsy of the temporal lobe of the brain. Children are a particularly vulnerable category of patients: in addition to persistent intellectual disabilities (mental retardation, they may have specific impairments in the form of mental and speech development delay, learning difficulties, attention deficit hyperactivity disorder.Causes of cognitive and mental disorders in epilepsy can directly be the factor underlying epilepsy (genetic disease, structural brain defect, etc., epileptic seizures, interictal epileptiform activity, side effects of antiepileptic drugs (AED. In many cases, a patient with epilepsy combines several of these causes, and it is often difficult to determine which one cause is leading. The contribution of specific factors is difficult to estimate, because different factors can have an independent different effect on cognitive impairment. Some of causes underlying cognitive and mental disorders in epilepsy can be influenced and thus reduce the existing risk. Such measures include early diagnosis and effective adequate treatment of epileptic encephalopathy, as early as possible control of seizures, justified appointment of AED in children with cognitive impairment of unknown etiology and frequent epileptiform discharges on the electroencephalogram, careful monitoring of cognitive side effects of AED and

Equally unequal: gender discrimination in the workplace among adults with mental retardation.

Julius, Elona; Wolfson, Hagit; Yalon-Chamovitz, Shira

2003-01-01

Gender discrimination in the work place has been widely reported. Women are usually discriminated against both with respect to level of occupation and salary. The current study explored the correlation between gender and employment among adults with mental retardation, specifically, whether gender discrimination in the work place is as prominent among people with mental retardation as in the general population. Level of occupation and salary earned were studied in 227 adults with mild and moderate mental retardation residing in institutions, hostels, and sheltered homes in Israel. The findings suggest a correlation between gender and employment similar to that in the general population. Women were found to be employed mainly in sheltered workshops and lower levels of occupation, and to earn significantly less than the men. However, closer examination of each work place revealed that within each level of occupation there were no significant gender differences in salary. The finding suggests that while women with mental retardation earn lower salaries than men, this is mainly the result of their lower level of occupation. Rehabilitation efforts should therefore be directed toward ensuring higher levels of occupation as well as community employment among women with mental retardation.

Qurashi, Abrar; Chang, Shuang; Jin, Peng

2007-01-01

Deficits in cognitive functions lead to mental retardation (MR). Understanding the genetic basis of inherited MR has provided insights into the pathogenesis of MR. Fragile X syndrome is one of the most common forms of inherited MR, caused by the loss of functional Fragile X Mental Retardation Protein (FMRP). MicroRNAs (miRNAs) are endogenous, single-stranded RNAs between 18 and 25 nucleotides in length, which have been implicated in diversified biological pathways. Recent studies have linked the miRNA pathway to fragile X syndrome. Here we review the role of the miRNA pathway in fragile X syndrome and discuss its implication in MR in general. PMID:17982588

Hair samples of mildly mentally retarded (LR), moderately mentally retarded (MR), severely mentally retarded (SR) and normal children were collected and measured, using neutron activation analysis and X-ray fluorescence to determine the concentrations of Al, Sb, As, Ca, Cu, I, Fe Pb, Mg, Mn, Hg, K, Sr, S, V and Zn. The groups of children were of ages between 5 and 13. Difference in the mean concentration of each element between groups was tested by Student's t-test. No trend, either decreasing or increasing, has been established as the degree of severity increased from normal to SR children, except for the case of Cu. The present work may shed some light in the interpretation of findings on the effects of trace elements on neurobehavioral functions. (author)

Malnutrition as a cause of mental retardation: A population-based study from Sub-Himalayan India

Directory of Open Access Journals (Sweden)

Sunil Kumar Raina

2016-01-01

Full Text Available Background: Mental retardation is one of the most common disabilities of childhood. The research on childhood malnutrition and its relationship with cognitive functioning suggests that malnutrition alone does not cause mental retardation. Objective: To identify the relation between malnutrition and cognition among children from a Sub-Himalayan state in North India. Materials and Methods: A two-phase cross-sectional study was conducted in the rural, urban, and slum area of district Kangra. A 30-cluster sampling technique was used to screen a population of children 1–10 years of age from five randomly selected panchayats (village government units of district Kangra. The screening was based on a modified version of the ten questions screen, adapted to the local population. In the first phase, a door-to-door survey was done to identify suspects of mental retardation. In the second phase, the children found positive in the first phase were called for clinical examination to confirm mental retardation. Anthropometric assessment of all study children was done by measuring weight and height. The nutritional assessment was done by categorizing them according to Waterlow classification for malnutrition. Results: Out of the total 5300 children, 1.7% were diagnosed as mentally retarded. No positive association was reported with different types of malnutrition and mental retardation. A weakly positive association existed between nutritional status and mental retardation (correlation coefficient-0.04. Children who were both wasted and stunted had the highest risk (odds ratio, 95% confidence interval - 5.57, 2.29–10.36 of mental retardation as compared to normal. Conclusion: Malnutrition may be one of the causes but certainly not the only cause of mental retardation. Other causes may be contributing more significantly toward it.

The results of clinical, genealogical, cytogenetic and molecular genetic studies of 113 patients from 96 families with different forms of mental retardation from Ukraine are presented. This study was held as part of the CHERISH project of the 7-th Framework Program. The aim of the project is to improve diagnostics of mental retardation in children in Eastern Europe and Central Asia through detailed analysis of known chromosomal and gene's aberrations and to find the new gene-candidates that cause mental retardation. All patients have normal chromosome number (46XY or 46XX). The cases with fragile-X syndrome were eliminated using molecular genetic methods. Genome rearrangements were found among 28 patients using cytogenetic analysis, multiplex ligation-dependent probe amplification (MLPA analysis) ofsubtelomeric regions and array-based comparative genomic hybridisation (array CGH screening). In 10 cases known pathogenic CNV's were identified, 11 cases are unknown aberrations; their pathogenicity is being determined. The rest cases are known nonpathogenic gene rearrangements. Obtained results show the strong genetic heterogeneity of hereditary forms of mental retardation. The further studies will allow to identificate genes candidates and certain mutations in these genes that may be associated with this pathology.

In utero exposure to A-bomb radiation and mental retardation; a reassessment

International Nuclear Information System (INIS)

Otake, M.; Schull, W.J.

1984-01-01

The prevalence of mental retardation in children exposed in utero to the atomic bombs in Hiroshima and Nagasaki has been re-evaluated in reference to gestational age and tissue dose in the fetus. There was no risk at 0-8 weeks post-conception. The highest risk of forebrain damage occurred at 8-15 weeks of gestational age, the time when the most rapid proliferation of neuronal elements and when most, if not all, neuroblast migration to the cerebral cortex from the proliferative zones is occurring. Overall, the risk is five or more times greater in these weeks than in subsequent ones. In the critical period, damage expressed as the frequency of subsequent mental retardation appears to be linearly related to the dose received by the fetus. A linear model is not equally applicable to radiation-related mental retardation after the 15th week, the observed values suggesting that there a threshold may exist. The data are consistent with a probability of occurrence of mental retardation of 0.40% per cGy or 40% per gray. (author)

Full Text Available Purpose: The aim of this work is to assess the relationship between the environment and mentally retarded persons. Material and methods: Information referring to social support of mentally retarded persons is a source material collected on the base of the data included in the Polish and foreign literature. The issues under discussion related to the following problems: social integration of persons with intellectual disabilities in a family and local environment, social functioning of people with mild intellectual disability, social rehabilitation of people with moderate, severe and profound intellectual disability and specific contact with people with disabilities. Results: For a person with an intellectual disability, the family is the source of acquisition of basic social skills that give him the opportunity for further development and performing certain social roles in a sense of safety. Full acceptance of the intellectually disabled, may dismiss their sense of shame and fear, and instill the satisfaction of belonging to a social community. Conclusions: Full social acceptance of people with intellectual disabilities is the basis for their assimilation and social functioning.

Myoclonic epilepsy associated with ragged-red fibers is one of the mitochondrial encephalomyopathies. Pathogenic mitochondrial DNA mutations have been identified in the mitochondrial transfer RNA (tRNA)(Lys) at positions 8344 and 8356. Characteristics of myoclonic epilepsy associated with ragged-red fibers include myoclonic epilepsy, generalized epilepsy, hearing loss, exercise intolerance, lactic acidosis, and ragged-red fibers. The elevated lactate level is one of the most important symptoms needed to make a diagnosis of mitochondrial encephalomyopathy. In the present case, however, myoclonic epilepsy was associated with ragged-red fibers but without increased lactate levels. Therefore, myoclonic epilepsy associated with ragged-red fibers should be suspected in a patient who has myoclonic epilepsy that is difficult to control with antiepileptic medications and who has other symptoms of mitochondrial disease, such as mental retardation, even if the patient's lactate level is normal.

Sternlicht, M

1979-01-01

The patterns of fears of institutionalized mentally retarded adults were studied in a sample of i2 moderately retarded men and women between the ages of 21-49. The direct questioning method was employed. Two interviews were held, two weeks apart; the first interview elicited the Ss' fears, while the second concerned the fears of their friends. A total of 146 responses were obtained, and these were categorized according to the types of fears: supernatural-natural events, animals, physical injury, psychological stress, egocentric responses, and no fears. The Ss displayed a higher percentage of fears in the preoperational stage than in the concrete operational stage. In a comparison of male to female fears, only one category, that of fears of animals, reached significance. The study suggested that the same developmental trend of fears that appears in normal children appears in the retarded as well, and these fears follow Piaget's level of cognitive development, proceeding from egocentric perceptions of causality to realistic cause and effect thinking.

Campbell, E M; Meyer, P A

1981-07-01

Performance of mentally retarded and nonretarded persons was compared in two experiments designed to identify processes of auditory sensory memory. In one study backward masking of pure tones occurred for a group of retarded adolescents; however, no differences in masking functions were obtained for the retarded group and control groups of equal CA and MA. In the second study a gap-detection task was used as an apparent index of echoic trace durability. Since retarded persons were hypothesized to have a less durable echoic trace, the unique prediction was made that they would outperform control subjects on the task. The retarded group was significantly more accurate and exhibited a lower threshold than did the nonretarded, CA-matched control group. The applicability of these tasks for investigations of mental development was noted, and suggestions were made concerning improvements and extensions of the present research. A theoretical model was proposed to incorporate te current pattern of results.

Between 1978 and 2010, approximately 5 million infants were born after in vitro fertilization (IVF) treatments. Yet limited information on neurodevelopment after IVF exists, especially after the first year of life. To examine the association between use of any IVF and different IVF procedures and the risk of autistic disorder and mental retardation in the offspring. A population-based, prospective cohort study using Swedish national health registers. Offspring born between 1982 and 2007 were followed up for a clinical diagnosis of autistic disorder or mental retardation until December 31, 2009. The exposure of interest was IVF, categorized according to whether intracytoplasmic sperm injection (ICSI) for male infertility was used and whether embryos were fresh or frozen. For ICSI, whether sperm were ejaculated or surgically extracted was also considered. Relative risks (RRs) for autistic disorder and mental retardation and rates per 100,000 person-years, comparing spontaneously conceived offspring with those born after an IVF procedure and comparing 5 IVF procedures used in Sweden vs IVF without ICSI with fresh embryo transfer, the most common treatment. We also analyzed the subgroup restricted to singletons. Of the more than 2.5 million infants born, 30,959 (1.2%) were conceived by IVF and were followed up for a mean 10 (SD, 6) years. Overall, 103 of 6959 children (1.5%) with autistic disorder and 180 of 15,830 (1.1%) with mental retardation were conceived by IVF. The RR for autistic disorder after any procedure compared with spontaneous conception was 1.14 (95% CI, 0.94-1.39; 19.0 vs 15.6 per 100,000 person-years). The RR for mental retardation was 1.18 (95% CI, 1.01-1.36; 46.3 vs 39.8 per 100,000 person-years). For both outcomes, there was no statistically significant association when restricting analysis to singletons. Compared with IVF without ICSI with fresh embryo transfer, there were statistically significantly increased risks of autistic disorder following

The present study was carried out to determine the prevalence of families having mental retardation in Pakistani population. We enrolled seven mentally retarded (MR) families with two or more affected individuals. Family history was taken to minimize the chances of other abnormalities. Pedigrees were drawn using the Cyrillic software (version 2.1). The structure of pedigrees shows that all the marriages are consanguineous and the families have recessive mode of inheritance. All the families were studied by linkage analysis to mental retardation locus (MRT1)/gene PRSS12. Three STR markers (D4S191, D4S2392, and D4S3024) in vicinity of mental retardation (MR) locus (MRT1)/gene PRSS12 were amplified on all the sample of each family by PCR. The PCR products were then genotyped on non denaturing polyacrylamide gel electrophoresis (PAGE). The Haplotype were constructed to determine the pattern of inheritance and also to determine that a family was linked or unlinked to gene PRSS12. One out of the seven families was potentially linked to gene PRSS12, while the other six families remain unlinked.

Full Text Available We investigated the chromosomal constitution of patients with mental retardation and/or congenital malformations in order to determine genetic causes for such disturbances. The GTG and CBG banding patterns were studied using phytohemagglutinin M-stimulated lymphocytes cultured from peripheral blood. Among 98 individuals with mental retardation and/or congenital malformations who were analyzed there were 12 cases of Down's syndrome, two of Edward's syndrome, one of Patau's syndrome, five of Turner's syndrome, two of Klinefelter's syndrome, one of "cri-du-chat" syndrome, one case of a balanced translocation between chromosomes 13 and 14, one case of a derivative chromosome and one of a marker chromosome. We found abnormal chromosomes in 26% of the patients, 82% of which were numerical abnormalities, with the remaining 18% being structural variants. We conclude that patients with mental retardation and/or congenital malformations should be routinely karyotyped.

Reducing the burden of pediatric mental illness requires greater knowledge of mental health and substance abuse (MHSA) outcomes in children who are at an increased risk of primary psychiatric illness. National data on hospital care for psychiatric illness in children with epilepsy are limited. We used the Kids' Inpatient Database (KID), the Healthcare Cost and Utilization Project (HCUP), and the Agency for Healthcare Research and Quality from 2003 to 2009 to examine MHSA hospitalization patterns in children with comorbid epilepsy. Nonparametric and regression analyses determined the association of comorbid epilepsy with specific MHSA diagnoses and examined the impact of epilepsy on length of stay (LOS) for such MHSA diagnoses while controlling for demographic, payer, and hospital characteristics. We observed 353,319 weighted MHSA hospitalizations of children ages 6-20; 3280 of these involved a child with epilepsy. Depression was the most common MHSA diagnosis in the general population (39.5%) whereas bipolar disorder was the most common MHSA diagnosis among children with epilepsy (36.2%). Multivariate logistic regression models revealed that children with comorbid epilepsy had greater adjusted odds of bipolar disorder (AOR: 1.17, 1.04-1.30), psychosis (AOR: 1.78, 1.51-2.09), sleep disorder (AOR: 5.90, 1.90-18.34), and suicide attempt/ideation (AOR: 3.20, 1.46-6.99) compared to the general MHSA inpatient population. Epilepsy was associated with a greater LOS and a higher adjusted incidence rate ratio (IRR) for prolonged LOS (IRR: 1.12, 1.09-1.17), particularly for suicide attempt/ideation (IRR: 3.74, 1.68-8.34). Children with epilepsy have distinct patterns of hospital care for mental illness and substance abuse and experience prolonged hospitalization for MHSA conditions. Strategies to reduce psychiatric hospitalizations in this population may require disease-specific approaches and should measure disease-relevant outcomes. Hospitals caring for large numbers of

Of Atkins and men: deviations from clinical definitions of mental retardation in death penalty cases.

Science.gov (United States)

Blume, John H; Johnson, Sheri Lynn; Seeds, Christopher

2009-01-01

Under Atkins v. Virginia, the Eighth Amendment exempts from execution individuals who meet the clinical definitions of mental retardation set forth by the American Association on Intellectual and Developmental Disabilities and the American Psychiatric Association. Both define mental retardation as significantly subaverage intellectual functioning accompanied by significant limitations in adaptive functioning, originating before the age of 18. Since Atkins, most jurisdictions have adopted definitions of mental retardation that conform to those definitions. But some states, looking often to stereotypes of persons with mental retardation, apply exclusion criteria that deviate from and are more restrictive than the accepted scientific and clinical definitions. These state deviations have the effect of excluding from Atkins's reach some individuals who plainly fall within the class it protects. This article focuses on the cases of Roger Cherry, Jeffrey Williams, Michael Stallings, and others, who represent an ever-growing number of individuals inappropriately excluded from Atkins. Left unaddressed, the state deviations discussed herein permit what Atkins does not: the death-sentencing and execution of some capital defendants who have mental retardation.

Objective To investigate the prevalence of four common neuropsychiatric disorders in Tibet, with an aim to providing information support to health planning. Methods The survey was carried out in four regions of Tibet. The sampling strategy was adapted from that of a national psychiatric epidemiological survey in China in 1982 and 1993. The Neurosis Screening Inventory, Screening Inventory for Alcohol Dependence and Related Problems, Child Intelligence Screening Inventory, and a questionnaire for the Detection of Epileptic Seizures were administered to the respondents through face to face interview. Those with a positive response and 10% of those with a negative response were further interviewed with the Structured Clinical Interview for DSM-IV Axis I Disorders (research version) (SCID-1 ). Anxiety disorders and alcohol used disorders were diagnosed according to the American Psychiatric Association: Diagnostic and Statistical Manual of Mental Disorders (4th edition) (DSM-IV). Hysteria and mental retardation were diagnosed according to the International Classification of Diseases, 10th edition (ICD10), and the Chinese Classification of Mental Disorders, 3rd edition (CCMD-3). Results The point prevalence of neuroses, alcohol-related disorders, mental retardation and epilepsy was 2. 56%, 4. 06%, 0. 28% and 0. 68%, respectively. The lifetime prevalence of neuroses, alcohol-related disorders, mental retardation and epilepsy was 2. 62% , 4. 24% , 0. 28% and 0. 72% , respectively. Conclusion Alcohol-related disorders and neuroses are the two common mental health problems in Tibet. Mental retardation and epilepsy are the two serious neuropsychiatric disorders affecting Tibetan children and adolescence. These disorders should be identified as priorities in the reginonal health planning in Tibet.%目的 了解神经症、酒使用障碍、精神发育迟滞和癫痫这4�

Full Text Available This presentation concerns a group for parents of mentally retarded children.A group of these parents receives professional help and environmental support. The parents are encouraged to assume responsibility in the everyday life educational process of their children.As Baker / 1980 / states: “ If parents cope better on daily basis with the child who has mental retardation, not only the child but also the parents would benefit”.Taking part in the group gave the parents:· the opportunity to meet other parents with the same children;· to talk to other parents and feel less isolated;· to share information and experiences, skills and ideas;· the opportunity to listen to the needs and problems of other parents;· to change the ways of working to meet the child’s needs;· share information about the possibilities of education and services;· parents are encouraged to meet together to support one another;· parents need a special approach to many problems existing in their families.· the education in the group puts the beginning of the work with the parents.The idea is to gather the efforts of specialists from different fields and to establish multi-disciplinary group aiming to work with the parents and create a good collaboration and partnership between them in order to improve the living conditions and services to the retarded persons.This paper reports on the development, evaluation and dissemination of the program for education of parents with mentally retarded children. At the Symposium we will be able to present the results of the effectiveness of the education.

Schizophrenia is one of the most incapacitating forms of mental disorder that runs a chronic and relapsing course. It typically starts in adolescence or early adulthood and can be life-long. It is more common in people with learning disabilities than in the general population. Its prodromal features include depression, anxiety, suspiciousness, social isolation and bizarre behaviour. It may result in significant functional, social and economic impairments. The care of patients with schizophrenia places a considerable burden on all carers including patient's family, health and social services. Treatment includes pharmacotherapy and psychosocial interventions. In this case report we describe a thirteen-year-old patient with schizophrenia who has a background history of mental retardation.

Mental health problems and parental anxiety in children with epilepsy were investigated. Parents of 83 children with epilepsy and 172 healthy children were asked to complete Strengths and Difficulties Questionnaire for their children and State-Trait Anxiety Inventory for themselves. In those with epilepsy, 39.8% (n: 33) were girls, 60.2% (n: 50) were boys and their mean age was 9.34 ± 3.99 years. Control group was more successful in school (p children with epilepsy was higher than control group (p children with epilepsy were higher. Children with epilepsy have more neuro-behavioral problems; and their parents have greater anxiety levels. Physicians should be in contact with children with epilepsy for the psychological health of the family besides seizure control.

Subjects who were exposed in utero to the atomic bombs in Hiroshima and Nagasaki, along with suitable controls, are examined annually at ABCC. Of the 1613 subjects in the study sample, 30 have gross mental retardation. Within 1500 m from the hypocenter the prevalence of mental retardation is 5 times as high as for the more distal subjects, and 6 to 15 weeks gestation was the most sensitive period. Even when subjects with possible explanations for their retardation are excluded the pattern of differences remains the same. All but two of the retarded subjects had a smaller than average head and for those who were within 1500 m this effect is accentuated. 17 references, 2 figures, 8 tables.

A long-term observation has been made in 58 patients (30 males and 28 females) with severe sequelae of neonatal anoxic encephalopathy. They aged from 8 months to 65 years. All of them had motor disturbances and profound mental retardation. Motor function was improved in 4 patients with aging. In contrast, motor activity deteriorated in 11 cases, of which 4 showed a mental regression. Among them, patients who had originally better motor ability than sitting were likely to deteriorate by uncontrollable epilepsy and/or excessive administration of anticonvulsants. Regression of the patients with worse motor ability like bedridden appeared to attributable hypertonia of muscles and bodily deformation. Fifteen cases showed an exacerbation of general condition which originated predominantly to respiratory distress. Twelve patients died including 6 exacerbated cases. Exacerbation or death may have occurred frequently in specific periods of infancy, adolescence and youth with the patients who showed very low motor function such as bedridden and no locomotion.

1988-10-01

Visual evoked potentials (VEPs) were recorded from 25 10- to 13-year-old mildly mentally retarded children and compared with those from 31 control children of the same age-range. Correlations of VEPs with age were weak, but a relationship between VEPs and IQ was demonstrated for the control group. The retarded group had significantly longer latencies and higher amplitude peaks than the control group, with the differences occurring primarily over non-specific cortex and for secondary components. Analysis also showed that the retarded group were neurophysiologically heterogeneous. Since the same children had been analyzed earlier by quantitative EEG methods, comparisons are made with respect to these two methods of investigating brain function.

Full Text Available Kinect has already been widely used in the area of retardation, and this study is to evaluate whether the Game System for Rehabilitation based on Kinect is effective for children with mental retardation. The subjects in this paper are 112 children with mental retardation in Zhejiang province of China. The Game System for Rehabilitation based on Kinect was applied to assist the rehabilitation of children. Before the training, the Pediatric Evaluation of Disability Inventory (PEDI was used to evaluate abilities of children, including self-care, mobility, and social function. And after having been trained for a month, the abilities of these children were evaluated again by PEDI. The results in this paper is that, after the application of Game System for Rehabilitation based on Kinect, the PEDI score of children is significantly higher than the score before training. And it can be concluded that the Game System for Rehabilitation based on Kinect can significantly improve self-care, mobility, and social function of children with MR.

Mutations in the cyclin-dependent kinase-like 5 gene (CDKL5) have been identified in female patients with early onset epileptic encephalopathy and severe mental retardation with a Rett-like phenotype. Subsequently CDKL5 mutations were shown to be associated with more diverse phenotypes including mild epilepsy and autism without epilepsy. Furthermore, CDKL5 mutations were found in patients with Angelman-like phenotype. The severity of epilepsy associated with CDKL5 mutations was recently shown to correlate with the type of CDKL5 mutations and epilepsy was identified to involve three distinct sequential stages. Here, we describe the phenotype of a severe form of neurodevelopmental disease in a female patient with a de novo nonsense mutation of the CDKL5 gene c.175C > T (p.R59X) affecting the catalytic domain of CDKL5 protein. Mutations in the CDKL5 gene are less common in males and can be associated with a genomic deletion as found in our male patient with a deletion of 0.3 Mb at Xp22.13 including the CDKL5 gene. We review phenotypes associated with CDKL5 mutations and examine putative relationships between the clinical epilepsy phenotype and the type of the mutation in the CDKL5 gene. © 2010 European Paediatric Neurology Society.

High level of periodontal problems of dental caries are frequently observed in mentally handicapped children. This group of patients presents various problems when they face dental treatments. Identification of such population and providing them affordable oral health care is the new concept. A systematic method for identification and screening of persons with mental retardation has been developed and is being followed. Cost and fear are the most commonly cited barriers to dental care. Physical or mental may lead to deterioration in self-care, and oral care state have a low priority. Risk factors are inter-related and are often barriers to oral health. With advancements in today's world sufficient information and support is available for each and every individual to lead a healthy life which include the access to the oral health care. Factors such as fear, anxiety and dental phobia plays a vital role in acceptance of dental care and also the delaying of dental care. Lack of knowledge of oral and dental disease, awareness or oral need, oral side-effects of medication and organization of dental services are highlighted in the literature. All health personnel should receive training to support the concept of primary oral health care. Training about dealing with such mentally handicapped people should be addressed urgently among the health professionals.

Ladd-Taylor, Molly

2014-01-01

Nonconsensual sterilization is usually seen as the by-product of a classist and racist society; disability is ignored. This article examines the 1973 sterilization of two young black girls from Alabama and other precedent-setting court cases involving the sterilization of "mentally retarded" white women to make disability more central to the historical analysis of sterilization. It analyzes the concept of mental retardation and the appeal of a surgical solution to birth control, assesses judicial deliberations over the "right to choose" contraceptive sterilization when the capacity to consent is in doubt, and reflects on the shadow of eugenics that hung over the sterilization debate in the 1970s and 1980s.

2012-05-01

The aims of this study were to evaluate the sleep habits of children with drug resistant epilepsy and to correlate sleep abnormalities with epilepsy and level of intelligence. Twenty five subjects with drug resistant epilepsy (14 males, age range 2-16.4 years) were recruited for this study. A control group was formed by 23 normal children. Two instruments to assess sleep habits were administered to the patients with epilepsy: a questionnaire on sleep habits (to preschool children) and a questionnaire on sleep behavior (for children aged more than seven years old); a cognitive test (Wechsler Intelligence Scale for Children-WISC) was also performed. Patients underwent a complete polysomnographic study and sleep parameters, including CAP, were analyzed and correlated according to cognitive-behavioral measures in children with epilepsy. Children with drug-resistant epilepsy and severe mental retardation showed sleep abnormalities such as low sleep efficiency, high percentage of wakefulness after sleep onset, reduced slow wave sleep, and reduced REM sleep. Sleep microstructure evaluated by means of CAP analysis showed a decrease in A1 index during N3 in patients with more severe cognitive impairment. Children with epilepsy and cognitive impairment (n=10) had higher Sleep Behavior Questionnaire for Children (SBQC) total scores (65.60 ± 18.56) compared to children with epilepsy and normal IQ (50.00 ± 10.40), pintellectual disability.

Death penalty support for special offender populations of legally convicted murderers: juveniles, the mentally retarded, and the mentally incompetent.

Science.gov (United States)

Boots, Denise Paquette; Heide, Kathleen M; Cochran, John K

2004-01-01

The U.S. Supreme Court recently re-examined the constitutionality of the death penalty in the context of two of three special offender populations of murderers (juveniles, mentally retarded, and mentally incompetent). The Court reaffirmed the imposition of the death penalty for juveniles 16 and 17, while reversing itself on the mentally retarded. In reaching its decision, the Court relied on society's "evolving standards of decency." Using Likert-type items, this study is the first to have prospective jurors assess support for the death penalty for these specific offender groups. The public's support for the execution of each of the groups is then compared with existing case law. Descriptive statistics and regression analyses indicate that, as expected, the levels of support for the applicability of capital punishment to the various special offender populations are much lower than that for the general adult offender. Moreover, these findings are congruent with the holdings of the Court with one notable exception: a slight majority of respondents supported executing the mentally incompetent. Reasons for the public's apparent departure from the Supreme Court holding prohibiting the execution of mentally incompetent convicted murderers are discussed. The Court's continued role in protecting marginalized populations from "cruel and unusual punishment" is explored in the context of strong public sentiment demanding justice and finality despite changes in offenders' mental capacity.

Full Text Available Objective:Having a good quality of life has always been desirable for humans, and the concept of a good life and the ways of achieving it have become important over the years. Personal wellbeing is the mental component of quality of life. Thus, the current study was conducted to assess the reliability and validity of the ‘‘Personal Well-Being Index- Cognitive Disability’’ on mentally retarded students.Method:200 mentally retarded students in north districts of Tehran (districts 1, 2 and 3 were selected by systematic random sampling. The collected data using Personal Well-Being Index- Cognitive Disability was analyzed by Cronbach’s alpha coefficient for internal consistency and linear multivariate regression for construct validity.Results:Results confirmed the reliability and validity for the Personal Well-Being Index- Cognitive Disability in mentally retarded students of exceptional schools. Studying the internal consistency of seven items showed that all the items were correlated with the total score and their scores averages were similar to each other. This indicates that the test’s questions have reliability with regard to evaluation of a common feature and results showed Personal Well-Being Index- Cognitive Disability had the most extensive coverage of construct validity .Conclusion:Personal Well-Being Index- Cognitive Disability scale could be applied to measure personal wellbeing in mentally retarded students.

Deceased loved ones in the dreams of mentally retarded adults.

Turner, J L; Graffam, J H

1987-11-01

Dream reports were collected over a 10-year period as part of an ethnographic study of mentally retarded employees in a sheltered workshop. Deceased loved ones, usually parents or other family members, figured prominently as characters in many of these dreams. Dreams about the dead were often recurring and elicited salient emotional reactions from the dreamers. The various forms that these dreams take and their characteristic thematic content were described for 154 dreams by 60 dreamers. Some of the percepts and feelings that reflect the dreamers' understanding of their dreams were also noted. Findings reveal that the dream life of retarded adults is much more rich and diverse than previous studies suggest. Clinical implications and the occurrence of similar dreams among nonretarded persons were discussed.

PGAP2 (Post-GPI Attachment to Proteins 2) gene is involved in lipid remodeling steps of Glycosylphosphatidylinositol (GPI)-anchor maturation. At the surface of the cell this gene is required for proper expression of GPI-anchored proteins. Hyperphosphatasia with mental retardation syndrome-3 is an autosomal recessive disorder usually characterized by severe mental retardation. Mutations in the PGAP2 gene cause hyperphosphatasia mental retardation syndrome-3. We have identified a large consanguineous family from Saudi origin segregating developmental delay, intellectual disability, epilepsy and microcephaly. Whole exome sequencing with 100× coverage was performed on two affected siblings of the family. Data analysis in the patient revealed a novel missense mutation c.191C>T in PGAP2 gene resulting in Alanine to Valine substitution (Ala64Val). The mutation was reconfirmed and validated by subsequent Sanger sequencing method. The mutation was ruled out in 100 unrelated healthy controls. We suggest that this pathogenic mutation disrupts the proper function of the gene proteins resulting in the disease state. Copyright © 2016 Elsevier B.V. All rights reserved.

An outbreak of El Tor cholera in an institution for the mentally retarded in Nonthaburi, June-July 1987.

Swaddiwudhipong, W; Limpakarnjanarat, K

1991-06-01

In June and July 1987, an outbreak of cholera caused by V.cholerae O1, biotype El Tor, serotype Inaba, occurred in an institution for the mentally retarded in Nonthaburi. Of the 447 retarded inmates, 74 were found to be infected and one died. Epidemiological investigation revealed that the inmates with severe mental retardation who ate food in their own sleeping-room were significantly (p less than 0.001) more likely to be infected than those taking food in the dining-room. We hypothesize that the liquid diet commonly served to the more severely mentally retarded may have increased the risk of infection by more rapid gastric emptying. The long average period of time for meal consumption among these individuals may have allowed the organisms to multiply to a level capable of causing disease. Contamination of food with cholera might have occurred during food handling in the kitchen or within the sleeping-room where overcrowded conditions and poor personal hygiene facilitated person-to-person spread of infection. Prompt implementation of control measures effectively terminated cholera transmission in the outbreak.

Cryptic structural abnormalities within the subtelomeric regions of chromosomes have been the focus of much recent research because of their discovery in a percentage of people with mental retardation (UK terminology: learning disability). These studies focused on subjects (largely children) with various severities of intellectual impairment with or without additional physical clinical features such as dysmorphisms. However it is well established that prevalence of schizophrenia is around three times greater in those with mild mental retardation. The rates of bipolar disorder and major depressive disorder have also been reported as increased in people with mental retardation. We describe here a screen for telomeric abnormalities in a cohort of 69 patients in which mental retardation co-exists with severe psychiatric illness. We have applied two techniques, subtelomeric fluorescence in situ hybridisation (FISH) and multiplex amplifiable probe hybridisation (MAPH) to detect abnormalities in the patient group. A subtelomeric deletion was discovered involving loss of 4q in a patient with co-morbid schizoaffective disorder and mental retardation. The precise region of loss has been defined allowing us to identify genes that may contribute to the clinical phenotype through hemizygosity. Interestingly, the region of 4q loss exactly matches that linked to bipolar affective disorder in a large multiply affected Australian kindred.

Law & psychiatry: mental retardation and the death penalty: after Atkins.

Science.gov (United States)

Appelbaum, Paul S

2009-10-01

In Atkins v. Virginia the U.S. Supreme Court declared execution of persons with mental retardation to constitute cruel and unusual punishment, and thus to be unconstitutional under the Eighth Amendment. However, the Court left all considerations regarding how to implement the decision explicitly to the states. Since Atkins was decided in 2002, legislatures, courts, and mental health experts have struggled with its implementation, highlighting the complexities that can arise when the courts base legal rules on clinical findings. This column reviews the Atkins case and considers the challenges associated with a clinical determination that can have life-or-death consequences for capital defendants.

Gabus, Caroline; Mazroui, Rachid; Tremblay, Sandra; Khandjian, Edouard W; Darlix, Jean-Luc

2004-01-01

The fragile X syndrome is the most common cause of inherited mental retardation resulting from the absence of the fragile X mental retardation protein (FMRP). FMRP contains two K-homology (KH) domains and one RGG box that are landmarks characteristic of RNA-binding proteins. In agreement with this, FMRP associates with messenger ribonucleoparticles (mRNPs) within actively translating ribosomes, and is thought to regulate translation of target mRNAs, including its own transcript. To investigate whether FMRP might chaperone nucleic acid folding and hybridization, we analysed the annealing and strand exchange activities of DNA oligonucleotides and the enhancement of ribozyme-directed RNA substrate cleavage by FMRP and deleted variants relative to canonical nucleic acid chaperones, such as the cellular YB-1/p50 protein and the retroviral nucleocapsid protein HIV-1 NCp7. FMRP was found to possess all the properties of a potent nucleic acid chaperone, requiring the KH motifs and RGG box for optimal activity. These findings suggest that FMRP may regulate translation by acting on RNA-RNA interactions and thus on the structural status of mRNAs.

2005-11-01

The aim of the study was to compare sleep patterns in children with epilepsy with those of their non-epileptic siblings and to determine which epilepsy-specific factors predict greater sleep disturbance. We conducted a case-control study of 55 children with epilepsy (mean age 10y, range 4 to 16y; 27 males, 28 females) and their nearest-aged non-epileptic sibling (mean age 10y, range 4 to 18y; 26 males, 29 females). Epilepsy was idiopathic generalized in eight children (15%), symptomatic generalized in seven (13%), and focal in 40 (73%); the mean duration was 5 years 8 months. Parents or caregivers completed the Sleep Behavior Questionnaire (SBQ) and Child Behavior Checklist (CBCL) for patients and controls, and the Quality of Life in Childhood Epilepsy (QOLCE) for patients. Patients had a higher (more adverse) Total Sleep score (p<0.001) and scored worse than controls on nearly all subscales of the SBQ. In patients, higher Total Sleep scores were correlated with higher scores on the Withdrawn, Somatic complaints, Social problems, and Attention subscales of the CBCL, and significantly lower Total Quality of Life Scores. Refractory epilepsy, mental retardation, and remote symptomatic etiology predicted greater sleep problems in those with epilepsy. We conclude that children with epilepsy in this current study had significantly greater sleep problems than their non-epileptic siblings.

2010-12-01

Full Text Available Introduction: The last decades have brought great advances in the understanding of child neurodevelopment and knowledge of cognitive processes that occur in the brain from an early age. As a result and thanks to the large number of standardized and scientifically guaranteed neuropsychological tests that are available today, we can assess and diagnose with high specificity, deficits or delays in the acquisition of cognitive functions. Besides, it allows knowing the strengths or normality points of children with various pathologies. Objective: To present the concepts and a neuropsychological assessment protocol for mental retardation, pervasive developmental disorder and psychomotor retardation. Development: First, the authors present a general model of neuropsychological assessment in childhood. Second, he concept, classification and aetiology of mental retardation is revised and it is proposed a neuropsychological profile. Finally, the paradigms of pervasive developmental disorder and psychomotor retardation are shown. Conclusion: Based on standardized and validated test for child neuropsychological assessment, children cognitive disorders can be accurately identified to plan each child's cognitive stimulation, and thus optimize the results of the therapy.

The fragile X syndrome is the most frequent form of inherited mental retardation in humans with an incidence of 1 in 1250 males and 1 in 2500 females. The clinical syndrome includes moderate to severe mental retardation, autistic behavior, macroorchidism, and facial features, such as long face with mandibular prognathism and large, everted ears. The molecular basis for this disease is a large expansion of a triplet repeat (CGG){sub n} in the 5{prime} untranslated region of the FMR1 gene. Due to this large expansion of the CGG repeat, the promoter region becomes methylated and the FMR1 gene is subsequently silenced. Hardly anything is known about the physiologic function of FMR1 and the pathologic mechanisms leading to these symptoms. Since the FMR1 gene is highly conserved in the mouse, we used the mouse to design a knockout model for the fragile X syndrome. These knockout mice lacking Fmrp have normal litter size suggesting that FMR1 is not essential in human gametogenesis and embryonic development. The knockout mice show the abnormalities also seen in the affected organs of human patients. Mutant mice show a gradual development through time of macroorchidism. In the knockout mice we observed cognitive defects in the form of deficits in learning (as shown by the hidden platform Morris water maze task) and behavioral abnormalities such as increased exploratory behavior and hyperactivity. Therefore this knockout mouse may serve as a valuable tool in studying the role of FMR1 in the fragile X syndrome and may serve as a model to elucidate the mechanisms involved in macroorchidism, abnormal behavior, and mental retardation.

In 1999, Hirose et al. reported a Japanese family with autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) associated with a neuronal nicotinic acetylcholine receptor α4 subunit mutation (S252L). We followed the siblings of this family, and found that the elder brother had Asperger's disorder without mental retardation (MR) and the younger brother had autistic disorder with profound MR. The clinical epileptic features of the siblings were very similar, and both had deficits in socialization, but their cognitive development differed markedly. It thus seems that epilepsy is the direct phenotype of the S252L mutation, whereas other various factors modulate the cognitive and social development. No patients with ADNFLE have previously been reported to have autism spectrum disorder or profound MR. Copyright © 2012 The Japanese Society of Child Neurology. Published by Elsevier B.V.

2004-08-01

Full Text Available Abstract Background Cryptic structural abnormalities within the subtelomeric regions of chromosomes have been the focus of much recent research because of their discovery in a percentage of people with mental retardation (UK terminology: learning disability. These studies focused on subjects (largely children with various severities of intellectual impairment with or without additional physical clinical features such as dysmorphisms. However it is well established that prevalence of schizophrenia is around three times greater in those with mild mental retardation. The rates of bipolar disorder and major depressive disorder have also been reported as increased in people with mental retardation. We describe here a screen for telomeric abnormalities in a cohort of 69 patients in which mental retardation co-exists with severe psychiatric illness. Methods We have applied two techniques, subtelomeric fluorescence in situ hybridisation (FISH and multiplex amplifiable probe hybridisation (MAPH to detect abnormalities in the patient group. Results A subtelomeric deletion was discovered involving loss of 4q in a patient with co-morbid schizoaffective disorder and mental retardation. Conclusion The precise region of loss has been defined allowing us to identify genes that may contribute to the clinical phenotype through hemizygosity. Interestingly, the region of 4q loss exactly matches that linked to bipolar affective disorder in a large multiply affected Australian kindred.

Fear of dental procedures deters many individuals with mental retardation from accepting dental treatment. This study was conducted to assess the effectiveness of two procedures, in vivo desensitization and video modeling, for increasing compliance with dental procedures in participants with severe or profound mental retardation. Desensitization increased compliance for all 5 participants, whereas video modeling increased compliance for only 1 of 3 participants.

Phenylketonuria (PKU) is the most common form of amino acid metabolism disorders with autosomal recessive inheritance. The brain damage can be prevented by early diagnosis and a phenylalanine-restricted diet. Untreated or late-treated patients may show mental retardation and other cognitive dysfunctions, as well as motor disability and/or epilepsy. Three patients with PKU and epilepsy were recognized to have reflex epileptic features, and there were ten consecutive adult patients with PKU and epilepsy who were evaluated retrospectively. Medical history, ages at diagnosis and therapy onset, age at seizure onset, seizure types and reflex features, neurological findings, cranial imaging, electroencephalography (EEG) findings, and final clinical condition were evaluated. Reflex epilepsy features were examined in detail. The cases (6 females, 4 males) were diagnosed at ages between 3.5months and 12years. All patients had various degrees of mental-motor retardation and focal or generalized seizures with age at seizure onset varied between neonatal period and 15years. Three patients had febrile seizure, 3 patients had myoclonia, and 3 patients had status epilepticus. All patients had abnormal EEG findings except one. There was a slowing of background activity, and generalized discharges were observed in 7 patients; 3 of them had asymmetrical discharges. One patient had right hippocampal sclerosis (HS), and another patient had hypointensities in the basal ganglia and corpus callosum. Reflex features were clinically observed in 3 of the patients; however, EEG results did not show any related findings. One patient had reflex seizures triggered by photic stimuli, hot water, and startling; one by photic stimuli; and the other one by startling. Reports on the clinical and electrophysiological features of adult patients with PKU were scant. We emphasized that reflex clinical features may be observed in this metabolic disease, and focal epileptiform abnormalities and asymmetry

This cross-sectional study aimed to describe the knowledge and perceptions about epilepsy and the attitudes toward people with epilepsy (PWEs) among university students in Yemen. A self-administered questionnaire was completed by 1155 students. Approximately 23% thought that epilepsy is a form of insanity, and 18% thought that it is a form of mental retardation. About 22% and 10% believed that evil spirits and an evil eye cause epilepsy, respectively. Similarly, 12% believed that children with epilepsy (CWEs) should be isolated from other children, while 12% and 14% thought that PWEs should not get married and should not have children, respectively. Approximately 23% of the students would not allow their child to play with CWEs, and 37% would not employ PWEs in a clerical job. Furthermore, 64% of the students would not agree to marry PWEs. Some misconceptions were strongly linked to attitudes toward PWEs. In conclusion, the negative attitudes toward PWEs among university students in Yemen were slightly more common compared with other settings in the Middle East and showed significant differences between genders which may warrant consideration when designing educational campaigns.

Objective: To detect brain structural difference between children with unexplained mental retardation and children with typically normal development. Methods: The high-resolution magnetic MR imaging were obtained from 21 children with unexplained mental retardation and 30 age-matched control children without intellectual disabilities. Voxel-based morphometry analysis with an optimization of spatial segmentation and normalization procedures were applied to compare differences of gray matter volume between the two groups. The total and regional gray matter volume were compared between the two groups with independent t test. Meanwhile, correlation was conducted to analyze the relationship between the total gray matter volume and intelligence quotient (IQ) with partial correlation test. Results: The total gray matter volume was significantly increased in the mental retardation children (1.012±0.079) × 10 6 mm 3 ] in relative to the controls [(0.956±0.059)×10 6 mm 3 , t=-2.80, P 0.05). Conclusions: VBM would detect the gray matter abnormalities that were not founded in routine MR scanning. The increase of gray matter volume in the frontal-thalamus network might indicate the delayed maturation of the brain development. This might be one of the causations of' mental retardation in children. (authors)

Full Text Available Objective: Giving birth and training to a child with Mental Retardation (MR can be stressful for mothers. Therefore mothers need role models and adequate preparation to effectively teach the child to function at optimum level within the environment. Nurses are in a strategic position to assume a vital role in a assisting these mothers. With observation, problem solving, and decision making. There is a lack of studies about mothers' experiences of having a child with MR. This study was preformed to investigate mother's experiences of having a child with MR and how explore and describe the experienced mothers with mental retarded child. Materials & Methods: A phenomenographic approach was used. The study was preformed at an exceptional school in Tehran. Twelve mothers were interviewed using guided interviews. Results: From 336 thematic sentences, Six categories emerged, the first having three subcategories and the second having twenty subcategories., the third having three, the fourth category having six, the fifth having two, and the sixth having two subcategories. Mother's experiences of having a child with MR, describes informants a variety of feelings, often ambivalent (acceptance and UN acceptance. In such a situation, attention to God and prayer are the most important coping strategies for positive adaptation in mothers' experiences of having a child with MR, but this perception can not effect to accept him alone. They emphasis on educational and psychological needs for better life. Conclusions: The findings of this study could be used in mothers education to promote understanding of mothers’ experiences and how best to help them. They could also be used in the general media to improve public understanding.

Studies on fragile X syndrome are scarce in Saudi Arabia and othercountries of the Arabian Peninsula. The few studies previously done haveeither been in the form of case reports or those performed oninstitutionalized mentally retarded patients. The aim of this study was todetermine the prevalence of fragile X syndrome among cases with mentalretardation who have been referred to the pediatric neurology clinics of KingKhalid University Hospital (KKUH) in Riyadh. Cytogenetic studies wereperformed in 94 cases that were referred to the pediatric neurology clinicsof KKUH because of mental retardation and/or delayed milestones ofdevelopment, from July 1995 to December 1997. Six male probands (6.4%) showedthe classic fragile X chromosome and another six (including a four year oldgirl) were detected, following extension of the cytogenetic studies to all 32first-degree relatives. Affection of more than one sibling was ascertained infour families. One family had four brothers with fragile X syndrome, whereasanother formed part of a large kindred with twelve males and five females whowere mentally retarded. A clinical, physical and psychological screeningchecklist was applied to the eleven affected males. Large testicular size,long face and short attention span were the most frequent features and eachwas detected in nine patients (82%). Pes planus and history of delayed speechwere found in eight patients (73%). The study showed that the fragile Xsyndrome clinical screening checklist has been applied in other populationsmight equally valuable and applicable among the population of Saudi Arabia.However, the presence of pale blue eyes can be excluded and more weight givento positive family history of mental to the most common clinical diagnosticfeatures of fragile X syndrome.

Full Text Available The aim of this research was to define the structure of speech disorder of children with a mild mental retardation. 100 subjects were chosen among pupils from the 1st to the 4th grade of elementary school who were under logopaedic treatment. To determine speech comprehension Reynell's developmental scales were used and for evaluation of speech articulation the Three-position test for articulation evaluation. With the Bender test we determined a child's mental age as well as defined the signs of psychological disfunction of organic nature. For the field of phonological consciousness a Test of reading and writing disturbances was applied. Speech fluency was evaluated by the Riley test. Evaluation scales were adapted for determining speech-language levels and motor skills of speech organs and hands. Data on results in psychological test and on the family was summed up from the diagnostic treatment guidance documents. Social behaviour in school was evaluated by their teachers. Six factors which hierarchicallydefine the structure of speech disorder were determined by the factor analysis. We found out that signs of a child's brain lesion are the factor which has the most influence on a child's mental age. The results of this research might be helpful to logopaedists in determining a logopaedic treatment for children with a mild mental retardation.

Rösche, J; Uhlmann, C; Weber, R; Fröscher, W

2003-04-01

Folate deficiency is common in patients with epilepsy and also occurs in patients with depression or cognitive deficits. This study investigates whether low serum folate levels may contribute to depressive mood and difficulties in mental processing in patients with epilepsy treated with anti-epileptic drugs inducing the cytochrome P450. We analysed the serum folate levels, the score in the Self Rating Depression Scale (SDS) and the results of a bedside test in mental processing in 54 patients with epilepsy. There was a significant negative correlation between the serum folate levels and the score in SDS and significant positive correlations between the score in SDS and the time needed to process an interference task or a letter-reading task. Low serum folate levels may contribute to depressive mood and therefore to difficulties in mental processing. Further studies utilizing total plasma homocysteine as a sensitive measure of functional folate deficiency and more elaborate tests of mental processing are required to elucidate the impact of folate metabolism on depressive mood and cognitive function in patients with epilepsy.

Objective: To assess how families perceive the positive and negative impacts of caring for a child with mental retardation. Methods: The quantitative descriptive study was conducted from January to August 2007 and comprised 54 families attending a private day-care centre for children with special needs in Karachi, Pakistan. The Kansas Inventory of Parental Perceptions was used to assess mothers' perceptions on the impact of caring for a child with mental retardation. Positive contributions, social comparisons with others, understanding of disability and perception of control were assessed. SPSS 16 was used for statistical analysis. Results: Mothers reported positive contribution to family life as a result of caring for a child with mental retardation (Mean: 2.95+-0.37). There was an acceptance of the situation and a trend towards upward favourable comparison with other families (Mean: 3.13+-0.07). Conclusions: Contrary to earlier studies exploring the impact of caring for a child with disabilities having largely focused on negative contributions, the study highlights some positive contributions.

Mental retardation after prenatal exposure. Re-analysis indicated

International Nuclear Information System (INIS)

Paile, W.

2000-01-01

The current risk assessment for severe mental retardation after prenatal exposure to the A-bomb radiation is based on 21 cases exposed to more than 0.005 Gy, of which 17 were exposed in the most sensitive period 8-15 weeks p.c. The latest analysis, applying the best fitting model, indicates a threshold with a lower 95% bound of 0.06-0.31 Gy, depending on whether 2 cases with Down's syndrome are included or not. The authors have interpreted this as suggesting a threshold in the low-dose region. In the dose group 0.10-0.49 Gy, except one case with Down's syndrome there is only one other case, exposed 8 weeks p.c. to 0.14 Gy. However, in a RERF report (TR 13-91) concerning brain abnormalities detected by MRI in retarded persons, the same case is described. According to this report he was actually exposed to 0.86 Gy. The distance was 1060 m, and his mother exhibited severe epilation. These details indicate that the higher dose is correct and the lower dose is erroneous. In a small material the misclassification of one case has a deep influence on the result of the data analysis. Reclassification of this case will lead to a considerable change in the estimated threshold, notably in the 95% lower bound of the threshold. There will be no indication of severe retardation after less than 0.5 Gy even in the most sensitive period. This does not preclude a milder effect on intelligence from lower doses. The fraction of severe retardation after exposure to 1 Sv in the period 8-15 weeks p.c. has been estimated at 40%. The effect on intelligence score has been estimated at 30 IQ units per Sv in the same period. These estimates have been combined in ICRP 60 to create a model, based on a presumed normal distribution of IQ scores, according to which the final outcome for an individual is determined by his expected IQ without exposure. Thus the dose required to make an otherwise normal individual retarded would be high, while a much lower dose would be enough to bring an individual

The incidence of psychogenic non-epileptic seizures (PNES) is 4.9/100,000/year and it is estimated that about 20-30% of patients referred to tertiary care epilepsy centers for refractory seizures have both epilepsy and PNES. The purpose of our study is to evaluate psychiatric disorders and neuropsychological functions among patients with PNES, patients with epilepsy associated with PNES and patients with epilepsy. We evaluated 66 consecutive in-patients with video-EEG recordings: 21 patients with epilepsy, 22 patients with PNES and 10 patients with epilepsy associated with PNES; 13 patients were excluded (8 because of mental retardation and 5 because they did not present seizures or PNES during the recording period). All patients with PNES had a psychiatric diagnosis (100%) vs. 52% of patients with epilepsy. Cluster B personality disorders were more common in patients with PNES. We observed fewer mood and anxiety disorders in patients with PNES compared with those with epilepsy. We did not find statistically significant differences in neuropsychological profiles among the 3 patient groups. This study can help to contribute to a better understanding of the impact of PNES manifestations, in addition to the occurrence of seizures, in order to provide patients with more appropriate clinical, psychological and social care.

Fragile X mental retardation protein participates in non-coding RNA pathways.

Science.gov (United States)

Li, En-Hui; Zhao, Xin; Zhang, Ce; Liu, Wei

2018-02-20

Fragile X syndrome is one of the most common forms of inherited intellectual disability. It is caused by mutations of the Fragile X mental retardation 1(FMR1) gene, resulting in either the loss or abnormal expression of the Fragile X mental retardation protein (FMRP). Recent research showed that FMRP participates in non-coding RNA pathways and plays various important roles in physiology, thereby extending our knowledge of the pathogenesis of the Fragile X syndrome. Initial studies showed that the Drosophila FMRP participates in siRNA and miRNA pathways by interacting with Dicer, Ago1 and Ago2, involved in neural activity and the fate determination of the germline stem cells. Subsequent studies showed that the Drosophila FMRP participates in piRNA pathway by interacting with Aub, Ago1 and Piwi in the maintenance of normal chromatin structures and genomic stability. More recent studies showed that FMRP is associated with lncRNA pathway, suggesting a potential role for the involvement in the clinical manifestations. In this review, we summarize the novel findings and explore the relationship between FMRP and non-coding RNA pathways, particularly the piRNA pathway, thereby providing critical insights on the molecular pathogenesis of Fragile X syndrome, and potential translational applications in clinical management of the disease.

Full Text Available Adult education of people with severe, modest and profound mental retardation got only recently an important place in the special education theory and practice. It could be established that in this area both in the intentional as well as in the contentual field the meaningfull shift has been achieved. Today we are talking about authonomy and rights of these people to taking part in a decission-making about the way of their living, but on the other  side the fast development and changes in society are again and again compelling this people to the decisions which they are not able to put into effect and which are burdening them and making them dependent of others. This could partly be prevented by continuing education as it is also true for them that in the stage of initial education they cannot subdue everything what they would need later in their life. Next to the findings of the foreign experts this has been confirmed as well in the first our investigations in this area. Some of the findings will be presented in our paper.

Full Text Available Objective: Study of the children psychomotor development, is and interdisciplinary interest among medical and rehabilitation specialist. The psychomotor development is mostly dependent on normal ontogenetically evolution of the brain, thus it is reasonable that any defects in this complicated process would be able to cause irreversible cognitive, sensory and motor dysfunction. In addition to mental deficiency in Mental Retarded (MR children, some other notable defects in motor abilities including gross and fine movement and equilibrium also exist in these children. Hemispheric dominancy or lateralization is an important stage in normal brain development which thought to be affected in MR children, and thus affects the outcome of rehabilitation treatment for these children. The present research work is designed to study functional cerebral lateralization between mentally retarded children having mental age of 5 to 6 years old and normal ones of the same age. Materials & Methods: By using the Neurological Developmental Questionnaire of Delacatom the functional lateralization parameters including footedness, handedness, and eye and ear preference were considered in this study. Results: Statistical analysis of the results showed significant differences in above mentioned parameters among MR and normal children of the same age. Conclusion: On the bases of these results, we believe that different pattern of lateralization in MR children could affect the rehabilitation management and should be noted in therapeutic plan.

Role of genetics in the etiopathogenesis of genetic generalized epilepsy: A review of current literature

Full Text Available Until recently, genetic generalized epilepsy (GGE was believed to be of presumed genetic etiology with no identifiable genetic mutation or demonstrable epigenetic abnormality. A wide range of epileptic disorders has clue for an inherited susceptibility. Monogenic disorders associated with epilepsy mental retardation and structural brain lesion typified by heterotopias, tuberous sclerosis, and progressive myoclonus epilepsies account for about 1% of epilepsies. This review focuses on the role of genetic mutations and epigenetic rearrangements in the pathophysiologic mechanism of GGE. To achieve this; PubMed, EMBASE, and Google Scholar were systematically and comprehensively searched using keywords (“epilepsy” “juvenile myoclonic epilepsy (JME,” “typical absences,” “idiopathic generalized epilepsy,” “JME,” “juvenile absence epilepsy,” “childhood absence epilepsy” “generalized tonic-clonic seizure” “GTCS”. Most GGE has evidence of underlying genetic inheritance. Recent animal studies have shown that early detection and treatment of genetic generalized epilepsies can alter the phenotypic presentation in rodents. These findings suggest a critical period in epileptogenesis, during which spike-and-wave seizures can be suppressed, leading to chronic changes in the brain (epileptogenesis and the preceding dysfunctions may, therefore, be targeted using therapeutic approaches that may either delay or inhibit the transition to active epileptic attack. The interplay between genetic mutations and epigenetic rearrangements play important roles in the development of GCE and that this process, especially at crucial developmental periods, is very susceptible to environmental modulations.

The purpose of the present study was to clarify the predictive value of age of walking for later motor performance in children with mental retardation. While paying due attention to other factors, our investigation focused on the relationship between a subject's age of walking, and his or her subsequent beam-walking performance. The subjects were 85 children with mental retardation with an average age of 13 years and 3 months. Beam-walking performance was measured by a procedure developed by the authors. Five low beams (5 cm) which varied in width (12.5, 10, 7.5, 5 and 2.5 cm) were employed. The performance of subjects was scored from zero to five points according to the width of the beam that they were able to walk without falling off. From the results of multiple regression analysis, three independent variables were found to be significantly related to beam-walking performance. The age of walking was the most basic variable: partial correlation coefficient (PCC) = -45; standardized partial regression coefficient (SPRC) = -0.41. The next variable in importance was walking duration (PCC = 0.38; SPRC = 0.31). The autism variable also contributed significantly (PCC = 0.28; SPRC = 0.22). Therefore, within the age range used in the present study, the age of walking in children with mental retardation was thought to have sufficient predictive value, even when the variables which might have possibly affected their subsequent performance were taken into consideration; the earlier the age of walking, the better the beam-walking performance.

We report several cases in which patients with autistic disorder with mental retardation who received risperidone experienced urinary incontinence. We retrospectively investigated the medical records of patients housed in facilities for patients with autistic disorder with mental retardation. Those who had undergone a medical examination at a hospital in Tokyo from April 1999 to March 2009 were included in the study.Retrospective data were gathered including age, sex, IQ, birth weight, dosage of risperidone, urinary density, as well as existence of urinary and fecal incontinence. We divided the participants into those who did and did not experience urinary incontinence after taking risperidone and compared the 2 groups. Risperidone had been prescribed to 35 patients. In spite of the fact that no patient had a history of urinary incontinence, 14 patients experienced urinary incontinence after receiving risperidone. Moreover, 4 of these 14 patients also had fecal incontinence. Among the variables we examined, the only significant difference between groups was in sex, with significantly more women experiencing incontinence compared with men. When the dose of risperidone was reduced or the patients switched to other drugs, urinary incontinence of the patients improved.Hence, risperidone may have a casual relationship with urinary incontinence. Further research is needed to understand the pathophysiology of possible effect.

Full Text Available Objective To study the clinical features of patients with Menkes' disease (MD that initiate from seizures, and to reinforce the knowledge of etiological diagnosis of secondary epilepsy.  Methods The clinical and laboratory features of 5 MD patients who were admitted from December 1992 to March 2014 were retrospectively analyzed.  Results All cases were male infants including two brothers, and the age of onset was 1-5 months after birth. Their clinical manifestations started from tonic (N = 3 and focal clonic (N = 2 seizures. The focal clonic seizures became more frequent and progressively worsened. Four cases showed abnormal background EEG rhythm; 3 cases revealed interictal focal or multifocal epileptiform discharges over occipital region predominantly; 2 cases revealed epileptic discharge in fit period EEG. All the cases manifested severe mental retardation accompanied with light complexion and curly hair. Low serum copper and ceruloplasmin levels were found in 4 cases and lead to the diagnosis of MD. The exceptional one was made clinical diagnosis of MD due to his typical manifestation and the diagnosis of his elder brother. Three cases received MRI examination, which showed extensive cerebral atrophy and symmetric encephalomalacia foci. One case revealed tortuosity of main artery and diminution of distal artery by MRA. One case was treated with phenobarbital, 2 cases with topiramate, one case with topiramate and levetiracetam and clonazepam. One case died of respiratory failure at 24 h after admission. The other 4 cases were followed up for 1-9 months after being discharged, 3 of whom died, and the left one converted to intractable infantile spasms and severe mental retardation, with interictal EEG changing to hypsarrhythmia.  Conclusions The onset of patients with epilepsy secondary to MD often occurs in early infancy, manifesting tonic and focal clonic seizures predominantly with interictal epileptiform discharges over the posterior

Mozart's Sonata for Two Pianos in D major, K.448 (Mozart K.448), has been shown to improve mental function, leading to what is known as the Mozart Effect. Our previous work revealed that epileptiform discharges in children with epilepsy decrease during and right after listening to Mozart K.448. However, the duration of the effect was not studied. In the study described here, we evaluated the long-term effect of Mozart K.448 on epileptiform discharges in children with epilepsy. Eighteen children with epilepsy whose seizures were clinically well controlled with antiepileptic drugs were included. For each child, EEGs had revealed persistent epileptiform discharges for at least 6 months. These patients listened to Mozart K.448 for 8 minutes once a day before bedtime for 6 months. Epileptiform discharges were recorded and compared before and after 1, 2, and 6 months of listening to Mozart K.448. All of the children remained on the same antiepileptic drug over the 6 months. Relationships between number of epileptiform discharges and foci of discharges, intelligence, epilepsy etiology, age, and gender were analyzed. Epileptiform discharges significantly decreased by 53.2±47.4, 64.4±47.1, and 71.6±45.8%, respectively, after listening to Mozart K.448 for 1, 2, and 6 months. All patients except those with occipital discharges showed a significant decrease in epileptiform discharges. Patients with normal intelligence and idiopathic epilepsy had greater decreases than those with mental retardation and symptomatic epilepsy. Age and gender did not affect the results. We conclude that long-term listening to Mozart K.448 may be effective in decreasing epileptiform discharges in children with epilepsy in a chronologically progressive manner.

Hereditary sensory and autonomic neuropathy type IV is an autosomal recessive disorder characterized by severe mental retardation and self-mutilation-related complications. Recently, we investigated a 16-year-old Korean boy with normal intelligence. He had preserved pain sensation but was suspected of having hereditary sensory and autonomic neuropathy type IV because of the recurrent bone fractures and painless joint destruction in the absence of any predisposing medical conditions. Genetic analysis of the NTRK1 gene revealed compound heterozygous mutations including c.851-33T>A and c.2303C>T (p.Pro768Leu) in the NTRK1 gene. The p.Pro768Leu mutation has been identified in 2 Japanese patients with a mild phenotype. Therefore, although it is rare, hereditary sensory and autonomic neuropathy type IV should be considered in patients with recurrent bone fractures and painless joint destruction who do not have any predisposing conditions even when they do not have typical clinical features such as mental retardation or pain insensitivity.

The relationship between job search skills and employability for persons with mild mental retardation.

Suzuki, Y

1998-01-01

Persons with mental retardation who possess applicable adaptive skills are usually able to obtain jobs in labor markets. However, some persons who show high scores with social and prevocational skills are unable to obtain jobs and the reasons for their unemployability are unknown. Twelve subjects with mild retardation who failed to obtain jobs were evaluated for their social and prevocational skills at the Tokyo Metropolitan Rehabilitation Center for the Physically and Mentally Handicapped. The evaluation was performed using the Social and Prevocational Information Battery-Revised which was developed by Halpen and Irvin. The results showed 12 subjects presented lower scores either in the Job Search Skills area or in other areas in spite of their high scores on the Total Battery. Moreover, these subjects also showed behavior problems. The study suggests that those with high scores on the Total Battery, but low scores in Job Search Skills, show a tendency to fail to obtain a job in competitive job placement. It seems that these persons have adjustment problems and need special support services to secure their employability.

To evaluate the nutritional status of mentally retarded children in the region of Galicia in north-west Spain, on the basis of anthropometric variables. The following variables were determined in a sample of 128 mentally retarded children (81 M, 47 F): birthweight, bodyweight, height/length, head circumference, mid-arm circumference, mid-arm muscle circumference, triceps skinfold thickness, subscapular skinfold thickness, arm area, arm muscle area, arm fat area, arm lean-to-fat ratio, Shukla's nutrition index and Quetelet's body mass index (BMI). A preliminary statistical analysis indicated that most information content could be maintained considering only eight of these variables. A factor analysis of the resulting 8 x 128 (variables by subjects) data matrix was performed, identifying two factors (FA1 and FA2) that together explained 82% of total variance. Taking these factors as indicators of nutritional status, the data were analysed for possible effects of age, gender, socioeconomic and family environment, intelligence quotient (IQ), presence/absence of cerebral palsy, quality of diet, appetite and antiepileptic use. The analysis suggested that most subjects were in the normal nutrition range, but about 33% showed either borderline or definite malnutrition. Mean score on FA2 showed a significant negative correlation with age. Children with cerebral palsy had lower mean scores on both factors, and scores on both factors varied with IQ. Children with definite malnutrition had a significantly lower IQ than those in the normal nutrition range. Mean score on both factors varied with appetite and quality of diet. The mean FAI score of children from inland-rural areas was significantly lower than that of children from coastal or urban areas. Mean FA1 score increased with increasing age of the parents. The prevalence of obesity was 13% when obesity was defined on the basis of Shukla's nutrition index, and 19% when defined on the basis of FA1 score. Malnutrition as

An increased occurrence of severe mental retardation, with or without accompanying small head size, at specific gestational ages has been the most conspicuous effect on brain development of prenatal exposure to the bombings of Hiroshima and Nagasaki. A variety of biological mechanisms could be responsible for this finding, including cell killing and mismanaged neuronal migration. We describe here the findings on magnetic resonance imaging of the brains of five of these mentally retarded individuals, all of whom were exposed in the 8th through the 15th weeks following fertilization, the gestational period shown to be the most vulnerable to radiation-related damage. In the two cases exposed at the 8th or 9th week following fertilization, large areas of ectopic gray matter are seen, strong evidence of a failure of the neurons to migrate to their proper functional sites. The two individuals exposed in the 12th or 13th week show no readily recognized ectopic gray areas but do show mild macrogyria, which implies some impairment in the development of the cortical zone. Moreover, both have mega cisterna magna. Finally, the one individual seen who was exposed still later in development, in the 15th week, shows none of the changes seen in the other four individuals. This person's brain, though small, appears to have normal architecture. These findings are discussed in terms of the embryological events transpiring at the time of the prenatal exposure of these individuals to ionizing radiation. (author)

Introduction Epilepsy is a diverse set of chronic neurological disorders characterized by seizures. It is one of the most common of the serious neurological disorders. About 3% of people will be diagnosed with epilepsy at some time in their lives. Objectives We aimed to address the commonest types of seizures, their aetiologies, EEG and neuroimaging results and prognosis of patients presented to neurology services of the King Fahad Specialist Hospital- AlQassim (KFSH). Methodology In this retrospective epidemiological study we investigated the medical records of patients with epilepsy, who attended the neurology services of KFSH, during the study period (26/10/2011–26/4/2012). Results The study included 341 patients; 189 (55.4%) males and 152 (44.6%) females. Their ages ranged between 12 and 85 years (mean ± SD = 31±16.9). The majority of patients had Generalised Tonic Clonic Seizures (76.2%), followed by Complex Partial Seizures (7.6%). 73% of our patients had idiopathic epilepsy. The commonest causes for symptomatic epilepsy were Cerebro Vascular Accidents and Head trauma. Hemiplegia, mental retardation and psychiatric illness were the commonest comorbidity. 69.3% of patients had controlled seizures. Patients with idiopathic epilepsy were significantly controlled than patients with symptomatic epilepsy (P=0.01), and those using one Anti Epileptic Drug were significantly controlled compared to patients using polytherapy (P=0.0001) there was no significant relation between controlled seizure and duration of illness or hospitalization or EEG changes. Conclusion Seizure types, aetiology, drug therapy, Comorbidities and outcome in a tertiary care hospital in Saudi Arabia are similar to previous local and international studies. 35.3% of patients were hospitalized, higher rates than previous studies. Seizure control was better in generalized seizures and idiopathic epilepsy compared to complex partial seizures or partial seizures with secondary generalization and

We report that a 4-year-old boy presented with right unilateral complete cleft lip and palate, right anophthalmos, left congenital nystagmus, absence of the vomer bone, mental-motor retardation, and normal lymphocyte karyotype (46, XY). For reconstruction of the deformities, we performed cleft lip repair by Millard's rotation-advancement technique and planned cleft palate repair. This combination of cleft lip and palate, anophthalmos, congenital nystagmus, absent vomer bone, and mental-motor retardation has not, to our knowledge, previously been described. We suggest that this represents either another case of the rare Fryns "anophthalmia-plus" syndrome or a new syndrome.

Megavitamin treatment of mental retardation in children: a review of effects on behavior and cognition.

ABSTRACT Many forms of vitamin supplementation have been proposed for the treatment of behavioral and cognitive disorders in children with mental retardation. Except for nutrient deficiencies and selected inborn errors of metabolism, the efficacy of these treatments has not been established. Therapeutic supplementation with vitamin B(6) in Down syndrome and folie acid in fragile X syndrome was attempted following the identification of apparent biochemical aberrations involving the nutrients. Double-blind controlled trials have revealed no evidence that B(6) treatment was effective in Down syndrome. Very limited evidence, only among prepubertal subjects, suggested that behaviors improved with folie acid treatment in fragile X syndrome. There is less clarity of the scientific rationales for various combinations of vitamins (or vitamins and minerals) that have been promoted according to the concept of orthomolecular medicine. Well-designed controlled studies, with data presented in conformity with generally accepted scientific standards, have not supported the efficacy of megadose supplementation with 1) multivitamins in cognitive disabilities or attention deficit disorders, or 2) multivitamins and minerals in Down syndrome or other forms of mental retardation. Insufficient data are available to support claims made for vitamin B(6) and magnesium supplementation in autism. Research in the larger field of nutrient-behavior research has reinforced the need for studies to be more rigorously designed and to draw on the expertise of multiple disciplines. Evidence of toxic effects of nutrients continues to accrue, reinforcing the fact that megadoses should not be used indiscriminately or without physician monitoring. For children with mental retardation generally, assuring that established nutritional needs are met warrants primary consideration.

To search for CDKL5 gene mutations in boys presenting with severe early-onset encephalopathy and intractable epilepsy, a clinical picture very similar to that already described in girls with CDKL5 mutations. Eight boys (age range 3-16 years, mean age 8.5 years, SD 4.38) with severe or profound mental retardation and early-onset intractable seizures were selected for CDKL5 gene mutation screening by denaturing high-performance liquid chromatography analysis. We found three unrelated boys carrying three different missense mutations of the CDKL5 gene: c.872G>A (p.C291Y), c.863C>T (p.T288I), and c.533G>C (p.R178P). They presented early-onset, polymorphous, and drug-resistant seizures, mostly myoclonic and tonic or spasms. EEG showed epileptiform abnormalities which were multifocal during wakefulness, and pseudoperiodic bisynchronous during sleep. This study describes three boys carrying CDKL5 missense mutations and their detailed clinical and EEG data, and indicates that CDKL5 gene mutations may represent a cause of severe or profound mental retardation and early-onset intractable seizures, also in boys. Screening for CDKL5 mutations is strongly recommended in individuals with these clinical features.

The phenotypic nonspecificity of many forms of X-linked mental retardation has hampered attempts to classify them into clinically homogeneous groups. One such condition, described by Clark and Baraitser, has been the subject of a single pedigree report to date. We now describe a further pedigree whose affected members share many manifestations with those reported by Clark and Baraitser, and we consider the possible distinction between this condition and Atkin-Flaitz syndrome. 9 refs., 4 figs., 1 tab.

Full Text Available Objectives: Because of the importance of adaptive behaviors in socialand domestic lives, this study aimed at a comparison of various domainsof adaptive behaviors, between mentally retarded and normalindividuals.Methods: A number of 246 normal and 74 mentally retarded individuals(7-18 years of age, mean: 12±3.5 years, participated this study inTehran, Iran. Their adaptive behaviors scores, were obtained using"Adaptive Behavioral Scale, Residential & Community" (ABS-RC: 2,consisting of 18 domains of behavior. The scale was first translatedinto Persian by the professionals and then retranslated into English byanother translator, to ensure content non-distortion.Results: The following domains were significantly lower in mentallyretarded than in normal individuals: independent functioning, economicactivity, language development, number & time, prevocational/vocational activity, self direction, responsibility, socialization,disturbing interpersonal behavior, domestic activity, social engagement,conformity and trustworthiness. No significant difference was documentedin the physical development, stereotype & hyperactive behaviors,sexual behavior as well as self abuse behavior domains, betweenthe two groups.Conclusions: As mentally deficient subjects did worse than normalones in terms of many adaptive behavioral domains, it implies that theadaptive behavioral issues in such people might need a great deal ofattention and intervention. For these retarded people to function betterin their social and residential environment, it would be necessary todevelop their adaptive behaviors. This study may shed light on theimportance of attention to the adaptive behavioral domains of mentallyretarded people and also indicates the necessity of preventive measures,even for normal individuals.

Abnormalities in thyroid state may affect development and function of the brain and result in mental retardation (MR). Thyroid parameters have not been systematically investigated in institutionalized MR subjects. The objective is to measure thyroid parameters in a novel cohort of 946 institutionalized subjects. The TOP-R (Thyroid Origin of Psychomotor Retardation) study is a cross-sectional nation-wide multicentre study. Subjects with unexplained MR. The majority of the MR subjects had thyroid parameters within the reference range used in our laboratory. Antiepileptic drugs (AEDs) use affected thyroid hormones (T4: 102·1 ± 1·2 vs 83·9 ± 1·2 nmol/l, P hyperthyroidism was 5·2% and 2·8%, respectively. We report thyroid parameters in a cohort of institutionalized subjects with MR. Our findings substantiate the fact that AEDs affect thyroid hormone levels. Future studies will be employed to investigate genetic causes of MR related to abnormalities in thyroid hormone homeostasis. © 2011 Blackwell Publishing Ltd.

PCDH19-related epilepsy is a genetic disorder that was first described in 1971, then referred to as "epilepsy and mental retardation limited to females". PCDH19 has recently been identified as the responsible gene, but a detailed characterization of the seizure manifestation based on video-EEG recording is still limited. The purpose of this study was to elucidate features of the seizure semiology in children with PCDH19-related epilepsy. To do this, ictal video-EEG recordings of 26 convulsive seizures in three girls with PCDH19-related epilepsy were analysed. All seizures occurred in clusters, mainly during sleep accompanied by fever. The motor manifestations consisted of six sequential phases: "jerk", "reactive", "mild tonic", "fluttering", "mild clonic", and "postictal". Some phases were brief or lacking in some seizures, whereas others were long or pronounced. In the reactive phase, the patients looked fearful or startled with sudden jerks and turned over reactively. The tonic and clonic components were less intense compared with those of typical tonic-clonic seizures in other types of epilepsy. The fluttering phase was characterised initially by asymmetric, less rhythmic, and less synchronous tremulous movement and was then followed by the subtle clonic phase. Subtle oral automatism was observed in the postictal phase. The reactive, mild tonic, fluttering and mild clonic phases were most characteristic of seizures of PCDH19-related epilepsy. Ictal EEG started bilaterally and was symmetric in some patients but asymmetric in others. It showed asymmetric rhythmic discharges in some seizures at later phases. The electroclinical pattern of the phasic evolution of convulsive seizure suggests a focal onset seizure with secondary generalisation. Based on our findings, we propose that the six unique sequential phases in convulsive seizures suggest the diagnosis of PCDH19-related epilepsy when occurring in clusters with or without high fever in girls.

Fragile x mental retardation protein regulates proliferation and differentiation of adult neural stem/progenitor cells.

Directory of Open Access Journals (Sweden)

Yuping Luo

2010-04-01

Full Text Available Fragile X syndrome (FXS, the most common form of inherited mental retardation, is caused by the loss of functional fragile X mental retardation protein (FMRP. FMRP is an RNA-binding protein that can regulate the translation of specific mRNAs. Adult neurogenesis, a process considered important for neuroplasticity and memory, is regulated at multiple molecular levels. In this study, we investigated whether Fmrp deficiency affects adult neurogenesis. We show that in a mouse model of fragile X syndrome, adult neurogenesis is indeed altered. The loss of Fmrp increases the proliferation and alters the fate specification of adult neural progenitor/stem cells (aNPCs. We demonstrate that Fmrp regulates the protein expression of several components critical for aNPC function, including CDK4 and GSK3beta. Dysregulation of GSK3beta led to reduced Wnt signaling pathway activity, which altered the expression of neurogenin1 and the fate specification of aNPCs. These data unveil a novel regulatory role for Fmrp and translational regulation in adult neurogenesis.

Full Text Available One of the most fragile stratums of every society is the people with certain disabilities, especially educable mentally retarded children. Some of the most tangible difficulties of these people are seen in their perceptual and motional abilities (coordination, balance, atmospheric awareness, time awareness, physical awareness and sense of direction. Overcoming these inabilities requires the integration of environmental information and decision making for performance of a special function. The objective of the present research is to investigate the effects of eight weeks of Tai-Chi exercises on status parameters of Kyphosis and balance among educable mentally retarded children. The research sample is consisted of 30 educable mentally retarded children suffering from Kyphosis abnormality. The sample individuals were selected from welfare centers of Tehran. After selection of samples, prior and post to execution of the protocol, the individuals were measured in terms of Kyphosis angle, chest expansion, coefficient of Delmas, spine extension and static and dynamic balances respectively through flexible rulers, tape measure, stoke test and Y test. The educable mentally retarded children were assigned to two 15 individual groups of experimental (age average of 11.6 years; average height of 142.30; average weight of 39.26kg and control (age average of 11.06; height average of 139.83 and weight average of 35.86kg. The subjects of the experimental group were participated in an 8 week course of Tai-Chi exercises in three weekly 45 minute sessions. These exercises included a 10 minute warm-up, 30 minutes of Tai-Chi movements and 5 minutes of cool-down. During this time, the subjects of the control group were not incorporated into any exercise. By the use of the Shapiro-Wilk test, the normality of data distribution was investigated and approved. Also the Leon test was used for investigation of equality of the variances. Afterwards, descriptive statistics

Di Nuovo, Alessandro G; Di Nuovo, Santo; Buono, Serafino

The estimation of a person's intelligence quotient (IQ) by means of psychometric tests is indispensable in the application of psychological assessment to several fields. When complex tests as the Wechsler scales, which are the most commonly used and universally recognized parameter for the diagnosis of degrees of retardation, are not applicable, it is necessary to use other psycho-diagnostic tools more suited for the subject's specific condition. But to ensure a homogeneous diagnosis it is necessary to reach a common metric, thus, the aim of our work is to build models able to estimate accurately and reliably the Wechsler IQ, starting from different psycho-diagnostic tools. Four different psychometric tests (Leiter international performance scale; coloured progressive matrices test; the mental development scale; psycho educational profile), along with the Wechsler scale, were administered to a group of 40 mentally retarded subjects, with various pathologies, and control persons. The obtained database is used to evaluate Wechsler IQ estimation models starting from the scores obtained in the other tests. Five modelling methods, two statistical and three from machine learning, that belong to the family of artificial neural networks (ANNs) are employed to build the estimator. Several error metrics for estimated IQ and for retardation level classification are defined to compare the performance of the various models with univariate and multivariate analyses. Eight empirical studies show that, after ten-fold cross-validation, best average estimation error is of 3.37 IQ points and mental retardation level classification error of 7.5%. Furthermore our experiments prove the superior performance of ANN methods over statistical regression ones, because in all cases considered ANN models show the lowest estimation error (from 0.12 to 0.9 IQ points) and the lowest classification error (from 2.5% to 10%). Since the estimation performance is better than the confidence interval of

Full Text Available Fragile X syndrome is the most common inherited form of mental retardation. We investigated the prevalence of the Fragile X syndrome in the population with mental retardation of unknown etiology in Andalusia, South Spain. We analyzed 322 unrelated patients (280 males and 42 females, and found a fragile X syndrome frequency of 6.5%. Among the non-fragile X chromosomes, the 29 CGG repeat was the most common allele. At the linked microsatellite DXS548 locus, we found a new allele which we called "allele 10" (17 CA. Similar to other south European populations, allele 2 (25 CA at the DXS548 locus and the fragile X allele were in linkage disequilibrium supporting the idea of a common founder chromosome predisposing to the CGG expansion.

To evaluate the reliability and the validity of Landolt Rings and of the Frisby Test as measures of visual acuity and stereoacuity, respectively, the visual acuity of 30 mentally retarded children was measured with Landolt Rings shown as games, the Sjögren Test, the Dot Visual Acuity Test and stereoacuity with the Frisby Test. Subjects were tested 3 times over a period of 3 weeks to measure the reliability of the tests. No significant difference was observed among these tests. The validity of the Landolt Rings was measured by a correlation of .55 for the highest logMAR values of the Sjögren Test with the highest logMAR values of the Landolt Rings. Visual acuity was systematically lower on the Dot Visual Acuity Test. The Frisby Test was not reliable among a group of 16 normal children who improved systematically over 3 weeks.

Chernobyl nuclear catastrophe and the high risk potential for mental retardation

1993-01-01

The nuclear explosion at Chernobyl nuclear reactor on April 26, 1986, continues to have wide political, social, and medical ramifications. Hot debris from the Chernobyl reactor covered an area of more than 5,000 square kilometers with nearly 20 million curies of radionuclides. Eleven regions with a population of nearly 17 million people, of whom 2.5 million were children below the age of 5 years, suffered some degree of radioactive contamination. These children are currently of elementary school age. One of the tragedies of the explosion is that thousands of these children are at high risk for mental retardation and learning disorders

Protein implicated in nonsyndromic mental retardation regulates protein kinase A (PKA) activity

KAUST Repository

Altawashi, Azza

2012-02-28

Mutation of the coiled-coil and C2 domain-containing 1A (CC2D1A) gene, which encodes a C2 domain and DM14 domain-containing protein, has been linked to severe autosomal recessive nonsyndromic mental retardation. Using a mouse model that produces a truncated form of CC2D1A that lacks the C2 domain and three of the four DM14 domains, we show that CC2D1A is important for neuronal differentiation and brain development. CC2D1A mutant neurons are hypersensitive to stress and have a reduced capacitytoformdendritesandsynapsesinculture. Atthebiochemical level,CC2D1Atransduces signals to the cyclic adenosine 3?,5?-monophosphate (cAMP)-protein kinase A (PKA) pathway during neuronal cell differentiation. PKA activity is compromised, and the translocation of its catalytic subunit to the nucleus is also defective in CC2D1A mutant cells. Consistently, phosphorylation of the PKA target cAMP-responsive element-binding protein, at serine 133, is nearly abolished in CC2D1A mutant cells. The defects in cAMP/PKA signaling were observed in fibroblast, macrophage, and neuronal primary cells derived from the CC2D1A KO mice. CC2D1A associates with the cAMP-PKA complex following forskolin treatment and accumulates in vesicles or on the plasma membrane in wild-type cells, suggesting that CC2D1A may recruit the PKA complex to the membrane to facilitate signal transduction. Together, our data show that CC2D1A is an important regulator of the cAMP/PKA signaling pathway, which may be the underlying cause for impaired mental function in nonsyndromic mental retardation patients with CC2D1A mutation. 2012 by The American Society for Biochemistry and Molecular Biology, Inc.

2018-02-01

Full Text Available Background: Cerebellar ataxia, mental retardation, and disequilibrium syndrome (CAMRQ is a heterogeneous group of genetic disorders that have been grouped by shared clinical features; all of these features are transmitted via an autosomal recessive mechanism. Four variants of this syndrome have been identified so far, and each one differs in terms of both clinical and genotypical features. CAMRQ4 is a rare genetic disorder characterized by mental retardation, ataxia or an inability to walk, dysarthria and, in some patients, quadrupedal gait. Methods: We investigated three Saudi families with CAMRQ4. Blood samples were collected from the affected patients, their parents, and healthy siblings. DNA was extracted from whole blood, and whole-exome sequencing was performed. Findings were confirmed by segregation analysis, which was performed on other family members. Results: Thus far, 17 patients have been affected by CAMRQ4. Genetic analysis of all patients, including our current patients, showed a mutation in the aminophospholipid transporter, class I, type 8A, member 2 gene ( ATP8A2 . A series of common phenotypical features have been reported in these patients, with few exceptions. Ataxia, mental retardation, and hypotonia were present in all patients, consanguinity in 90% and abnormal movements in 50%. Moreover, 40% achieved ambulation at least once in their lifetime, 40% had microcephaly, whereas 30% were mute. Magnetic resonance imaging (MRI of the brain was normal in 60% of patients. Conclusions: We described the largest cohort of patients with CAMRQ4 syndrome and identified three novel mutations. CAMRQ4 syndrome should be suspected in patients presenting with ataxia, intellectual disability, hypotonia, microcephaly, choreoathetoid movements, ophthalmoplegia, and global developmental delay, even if brain MRI appears normal.

Flexibility is an intrinsic property of proteins and essential for their biological functions. However, because of structural flexibility, obtaining high-quality crystals of proteins with heterogeneous conformations remain challenging. Here, we show a novel approach to immobilize traditional precipitants onto molecularly imprinted polymers (MIPs) to facilitate protein crystallization, especially for flexible proteins. By applying this method, high-quality crystals of the flexible N-terminus of human fragile X mental retardation protein are obtained, whose absence causes the most common inherited mental retardation. A novel KH domain and an intermolecular disulfide bond are discovered, and several types of dimers are found in solution, thus providing insights into the function of this protein. Furthermore, the precipitant-immobilized MIPs (piMIPs) successfully facilitate flexible protein crystal formation for five model proteins with increased diffraction resolution. This highlights the potential of piMIPs for the crystallization of flexible proteins.

11p Microdeletion including WT1 but not PAX6, presenting with cataract, mental retardation, genital abnormalities and seizures: a case report

2009-02-01

Full Text Available Abstract WAGR syndrome (Wilms' tumor, aniridia, genitourinary abnormalities and mental retardation and Potocki-Shaffer syndrome are rare contiguous gene deletion syndromes caused by deletions of the 11p14-p12 chromosome region. We present a patient with mental retardation, unilateral cataract, bilateral ptosis, genital abnormalities, seizures and a dysmorphic face. Cytogenetic analysis showed a deletion on 11p that was further characterized using FISH and MLPA analyses. The deletion (11p13-p12 located in the area between the deletions associated with the WAGR and Potocki-Shaffer syndromes had a maximum size of 8.5 Mb and encompasses 44 genes. Deletion of WT1 explains the genital abnormalities observed. As PAX6 was intact the cataract observed cannot be explained by a deletion of this gene. Seizures have been described in Potocki-Shaffer syndrome while mental retardation has been described in both WAGR and Potocki-Shaffer syndrome. Characterization of this patient contributes further to elucidate the function of the genes in the 11p14-p12 chromosome region.

Blepharophimosis is a rare congenital anomaly of the palpebral fissure which is often associated with mental retardation and additional malformations. We report on a boy with blepharophimosis, ptosis and severe mental retardation carrying an unbalanced 4;10 translocation with terminal duplication of 10q [dup(10)(q25.1-->qter)] and monosomy of a small terminal segment of chromosome 4q [del(4)(34.3-->qter)]. Detailed clinical examination and review of the literature showed that the phenotype of the patient was mainly determined by the dup(10q). This paper reviews the chromosomal aberrations associated with BMR (blepharophimosis mental retardation) phenotypes. Searching different databases and reviewing the literature revealed 14 microscopically visible aberrations (among them UPD(14)pat) and two submicroscopic rearrangements causing blepharophimosis and mental retardation (BMR) syndrome. Some of these rearrangements-like the terminal dup(10q) identified in our patient or interstitial del(2q)-are associated with clearly defined phenotypes and can be well distinguished from each other on basis of clinical examination. This paper should assist clinicians and cytogeneticists when evaluating patients with BMR syndrome.

MENTAL RETARDATION (MR) is one of the mostfrequent and debilitating neurological handicaps inchildren and one of the few clinically important dis-orders for which the etiopathogenesis is still poorlyunderstood. MR is currently defined as a signifi-cant impairment of cognitive and adaptive functions,with onset before age 18. Recently, the prevalenceof MR in the Chinese population was estimated tobe 1.2%1 in comparison with 1%-10%2 in westerncountries. The prevalence of MR in a large popula-tion in Wuhang (97...

Epilepsy is, of course, not one disease but rather a huge number of disorders that can present with seizures. In common, they all reflect brain dysfunction. Moreover, they can affect the mind and, of course, behavior. While animals too may suffer from epilepsy, as far as we know, the electrical discharges are less likely to affect the mind and behavior, which is not surprising. While the epileptic seizures themselves are episodic, the mental and behavioral changes continue, in many cases, interictally. The episodic mental and behavioral manifestations are more dramatic, while the interictal ones are easier to study with anatomical and functional studies. The following extended summaries complement those presented in Part 1. PMID:23764496

Multifarious Functions of the Fragile X Mental Retardation Protein.

Davis, Jenna K; Broadie, Kendal

2017-10-01

Fragile X syndrome (FXS), a heritable intellectual and autism spectrum disorder (ASD), results from the loss of Fragile X mental retardation protein (FMRP). This neurodevelopmental disease state exhibits neural circuit hyperconnectivity and hyperexcitability. Canonically, FMRP functions as an mRNA-binding translation suppressor, but recent findings have enormously expanded its proposed roles. Although connections between burgeoning FMRP functions remain unknown, recent advances have extended understanding of its involvement in RNA, channel, and protein binding that modulate calcium signaling, activity-dependent critical period development, and the excitation-inhibition (E/I) neural circuitry balance. In this review, we contextualize 3 years of FXS model research. Future directions extrapolated from recent advances focus on discovering links between FMRP roles to determine whether FMRP has a multitude of unrelated functions or whether combinatorial mechanisms can explain its multifaceted existence.

Fragile X mental retardation protein controls synaptic vesicle exocytosis by modulating N-type calcium channel density

Science.gov (United States)

Ferron, Laurent; Nieto-Rostro, Manuela; Cassidy, John S.; Dolphin, Annette C.

2014-04-01

Fragile X syndrome (FXS), the most common heritable form of mental retardation, is characterized by synaptic dysfunction. Synaptic transmission depends critically on presynaptic calcium entry via voltage-gated calcium (CaV) channels. Here we show that the functional expression of neuronal N-type CaV channels (CaV2.2) is regulated by fragile X mental retardation protein (FMRP). We find that FMRP knockdown in dorsal root ganglion neurons increases CaV channel density in somata and in presynaptic terminals. We then show that FMRP controls CaV2.2 surface expression by targeting the channels to the proteasome for degradation. The interaction between FMRP and CaV2.2 occurs between the carboxy-terminal domain of FMRP and domains of CaV2.2 known to interact with the neurotransmitter release machinery. Finally, we show that FMRP controls synaptic exocytosis via CaV2.2 channels. Our data indicate that FMRP is a potent regulator of presynaptic activity, and its loss is likely to contribute to synaptic dysfunction in FXS.

2-methylbutyryl-CoA dehydrogenase deficiency associated with autism and mental retardation: a case report

2007-09-01

Full Text Available Abstract Background 2-methylbutyryl-CoA dehydrogenase deficiency or short/branched chain acyl-CoA dehydrogenase deficiency (SBCADD is caused by a defect in the degradation pathway of the amino acid L-isoleucine. Methods We report a four-year-old mentally retarded Somali boy with autism and a history of seizures, who was found to excrete increased amounts of 2-methylbutyryl glycine in the urine. The SBCAD gene was examined with sequence analysis. His development was assessed with psychometric testing before and after a trial with low protein diet. Results We found homozygosity for A > G changing the +3 position of intron 3 (c.303+3A > G in the SBCAD gene. Psychometric testing showed moderate mental retardation and behavioral scores within the autistic spectrum. No beneficial effect was detected after 5 months with a low protein diet. Conclusion This mutation was also found in two previously reported cases with SBCADD, both originating from Somalia and Eritrea, indicating that it is relatively prevalent in this population. Autism has not previously been described with mutations in this gene, thus expanding the clinical spectrum of SBCADD.

N-isopropyl-p[ 123 I]-iodoamphetamine (IMP) single photon emission computed tomography (SPECT), X-ray computed tomography (X-CT) and magnetic resonance imaging (MRI) were performed in 18 children with idiopathic seizures. In children with idiopathic seizures SPECT identified abnormal lesions in the highest rate (50%) compared with X-CT (11%) and MRI (13%), but the findings of SPECT poorly correlated with the foci on electroencephalography (EEG). Idiopathic epilepsy with abnormal uptake on SPECT was refractory to medical treatments and frequently associated with mental and/or developmental retardation. Perfusion defects identified on SPECT probably influenced the development of the brains in children. IMP SPECT is useful in the diagnosis and medical treatment in children with seizures. (author)

The psychiatrist should be given also their share in the prevetion of epilepsy by means of raising the psychiatric culture of the society and teaching the population the principles of mental hygiene and psychoprophylaxia. The possibilities of psychiatry in prophylactic management of patients with developed epilepsy include: 1. Energetic measures for controlling attacks which has many psychoprophylactic aspects. 2. Prevention of psychotraumatizing situations leading to secondary neurotic, psychotic and other reactions and behaviour disorders of the type of homilopathy and sociopathy, 3. Counteracting the development of mental and social disability in epileptics. Treatment of epilepsy should be conducted from its very beginning in cooperation with psychiatrists and therapeutic psychologists. The probems of prophylaxis cannot be separated from prophylactic treatment, psychotherapy sociotherapy and rehabilitation.

Fragile X syndrome (FXS) is caused by the absence of the Fragile X Mental Retardation Protein (FMRP) in neurons. In the mouse, the lack of FMRP is associated with an excessive translation of hundreds of neuronal proteins, notably including postsynaptic proteins. This local protein synthesis deregulation is proposed to underlie the observed defects of glutamatergic synapse maturation and function and to affect preferentially the hundreds of mRNA species that were reported to bind to FMRP. How FMRP impacts synaptic protein translation and which mRNAs are most important for the pathology remain unclear. Here we show by cross-linking immunoprecipitation in cortical neurons that FMRP is mostly associated with one unique mRNA: diacylglycerol kinase kappa (Dgkκ), a master regulator that controls the switch between diacylglycerol and phosphatidic acid signaling pathways. The absence of FMRP in neurons abolishes group 1 metabotropic glutamate receptor-dependent DGK activity combined with a loss of Dgkκ expression. The reduction of Dgkκ in neurons is sufficient to cause dendritic spine abnormalities, synaptic plasticity alterations, and behavior disorders similar to those observed in the FXS mouse model. Overexpression of Dgkκ in neurons is able to rescue the dendritic spine defects of the Fragile X Mental Retardation 1 gene KO neurons. Together, these data suggest that Dgkκ deregulation contributes to FXS pathology and support a model where FMRP, by controlling the translation of Dgkκ, indirectly controls synaptic proteins translation and membrane properties by impacting lipid signaling in dendritic spine.

What do we learn from the mental retardation induced by prenatal exposure in Hiroshima and Nagasaki ?

Significant effects of exposure to ionizing radiation on the developing brain are seen among those individuals prenatally exposed in the 8th through 25th weeks after fertilization. These effects, particularly in the most sensitive period, 8-15 weeks after fertilization, manifest themselves as an increased frequency of severe mental retardation, a diminution in IQ score and in school performance, and an increase in the occurrence of seizures. Of 30 SMR cases, 18(60%) had small heads. About 10% of the individuals with small head sizes observed among the in utero clinical sample were mentally retarded when we exclude two probable nonradiation-related cases of Down's syndrome from the 19 SMR cases exposed 8-15 weeks after fertilization, the 95% lower bound of the threshold based on the new dosimetry system appears to be in the range of 0.12-0.23 Gy. In the 16-25 weeks period, the 95% lower bound of the threshold is 0.21 Gy both with and without inclusion of two probable nonirradiation retarded cases. In a regression analysis of IQ scores and school performance data, a greater linearity is suggested with the new dosimetry (DS86) than with the old (T65DR), but the changes in the mean IQ scores and school performances in the low dose region are similar to the changes emerging in the control group, particularly so with doses under 0.10Gy.

1989-01-01

Computed tomographic (CT) brain scanning was performed on fifty-eight infants and children with microcephaly. CT scans were useful for detecting unsuspected brain lesions and for diagnosing underlying diseases. The head size did not correlate with the CT findings, the degree of mental retardation, or the existence of motor disturbance or epilepsy. On the other hand, the CT findings were correlated with the degree of mental retardation, and the existence of motor disturbance or epilepsy. CT scans were useful for determining the prognosis of the microcephaly. (author)

Allogeneic fetal stem cell transplantation to child with psychomotor retardation: A case report

2016-01-01

Full Text Available Introduction. The consequences of autologous and allogeneic stem cell transplantation (stem cells of hematopoiesis, applied in adults and children suffering from leukemia or some other malignant disease, are well-known and sufficiently recognizable in pediatric clinical practice regardless of the indication for the treatment. However, the efficacy of fetal stem cell transplantation is unrecognizable when the indications are psychomotor retardation and epilepsy. Case Outline. With the exception of neurological psychiatric problems, a boy aged 9.5 years was in good general health before transplantation with allogeneic fetal stem cells. The main aim of allogeneic fetal stem cell transplantation was treatment of psychomotor retardation and epilepsy. After 13 months of treatment, he was admitted to hospital in a very serious, life-threatening condition due to sepsis and severe pleuropneumonia. The humoral immunity in the boy was adequate, unlike cellular immunity. The immune imbalance in terms of predominance of T-suppressor lymphocytes contributes to delayed and late development of sepsis and severe pleuropneumonia. The boy still shows the same severity of psychomotor retardation, dyslalia, epilepsy, strabismus and amblyopia. Conclusion. Implementation of fetal stem cell therapy for unconfirmed indications abuses the therapeutic approach, harms patients, misleads parents, and brings financial harm to the healthcare system of any country, including Serbia.

Full Text Available Introduction: Oral health of the mentally retarded (MR has received scant attention in the literature compared with the normal child even though they are much sufferer. Aim: To assess the impact of various sociodemographic factors on oral hygiene of MR subjects of Bhopal city. Materials and Methods: A descriptive cross-sectional study was conducted among 267 MR subjects enrolled at various institutions of Bhopal city. A pretested proforma was used to record information about demographic data, socioeconomic status, the intelligent quotient of inmates, type of mental retardation, and dietary habits. The clinical examination was done to evaluate oral hygiene of subjects using oral hygiene index-simplified (OHI-S. Descriptive statistics, Student's t-test, analysis of variance and multiple linear regression analysis was applied using Statistical Package for Social Sciences (SPSS software. Results: The mean OHI-S of MR was found out to be 2.51. Male had mean OHI-S of 2.95 while female had 1.65. Noninstitutionalized had poorer oral hygiene with mean OHI-S of 3.2. According to the degree of mental retardation, profound had the highest OHI-S score, i.e. 3.71 while mild had the lowest score, i.e. 1.01.

Alpha thalassaemia-mental retardation, X linked

Directory of Open Access Journals (Sweden)

Gibbons Richard

2006-05-01

Full Text Available Abstract X-linked alpha thalassaemia mental retardation (ATR-X syndrome in males is associated with profound developmental delay, facial dysmorphism, genital abnormalities and alpha thalassaemia. Female carriers are usually physically and intellectually normal. So far, 168 patients have been reported. Language is usually very limited. Seizures occur in about one third of the cases. While many patients are affectionate with their caregivers, some exhibit autistic-like behaviour. Patients present with facial hypotonia and a characteristic mouth. Genital abnormalities are observed in 80% of children and range from undescended testes to ambiguous genitalia. Alpha-thalassaemia is not always present. This syndrome is X-linked recessive and results from mutations in the ATRX gene. This gene encodes the widely expressed ATRX protein. ATRX mutations cause diverse changes in the pattern of DNA methylation at heterochromatic loci but it is not yet known whether this is responsible for the clinical phenotype. The diagnosis can be established by detection of alpha thalassaemia, identification of ATRX gene mutations, ATRX protein studies and X-inactivation studies. Genetic counselling can be offered to families. Management is multidisciplinary: young children must be carefully monitored for gastro-oesophageal reflux as it may cause death. A number of individuals with ATR-X are fit and well in their 30s and 40s.

We reevaluated a family previously described as having nonspecific X-linked mental retardation (XLMR) by Snyder and Robinson (MINI 309583). Clinical and DNA studies were conducted on 17 relatives, including 6 males with mild-to-moderate mental retardation, 3 carrier females, and 8 normal males. In contrast to the normal appearance and minimal clinical findings reported 22 years ago, affected males were found to have a characteristic set of clinical findings. These developed gradually over the first 2 decades, and included thin body build with diminished muscle mass, osteoporosis and kyphoscoliosis, slight facial asymmetry with a prominent lower lip, nasal speech, high narrow or cleft palate, and long great toes. Carrier females were clinically normal. Multipoint linkage analysis indicated linkage to markers distal to the 3{prime} end of DMD (DXS41 and DXS989), with a maximal lod score of 4.7. On the basis of these findings, this entity is redefined as XLMR syndrome. 22 refs., 6 figs., 2 tabs.

An interictal schizophrenia-like psychosis in an adult patient with 22q11.2 deletion syndrome

Directory of Open Access Journals (Sweden)

Yasutaka Tastuzawa

2015-01-01

Full Text Available In addition to causing polymalformative syndrome, 22q11.2 deletion can lead to various neuropsychiatric disorders including mental retardation, psychosis, and epilepsy. However, few reports regarding epilepsy-related psychosis in 22q11.2 deletion syndrome (22q11.2DS exist. We describe the clinical characteristics and course of 22q11.2DS in a Japanese patient with comorbid mild mental retardation, childhood-onset localization-related epilepsy, and adult-onset, interictal schizophrenia-like psychosis. From a diagnostic viewpoint, early detection of impaired intellectual functioning and hyperprolinemia in patients with epilepsy with 22q11.2DS may be helpful in predicting the developmental timing of interictal psychosis. From a therapeutic viewpoint, special attention needs to be paid to phenytoin-induced hypocalcemia in this syndrome.

X-linked mental retardation with neonatal hypotonia in a French family (MRX15): Gene assignment to Xp11.22-Xp21.1

Raynaud, M.; Dessay, B.; Ayrault, A.D. [INSERM, Marseille (France)] [and others

1996-07-12

Linkage analysis was performed in a family with non-specific X-linked mental retardation (MRX 15). Hypotonia in infancy was the most remarkable physical manifestation. The severity of mental deficiency was variable among the patients, but all of them had poor or absent speech. Significant lod scores at a recombination fraction of zero were detected with the marker loci DXS1126, DXS255, and DXS573 (Zmax = 2.01) and recombination was observed with the two flanking loci DXS164 (Xp21.1) and DXS988 (Xp11.22), identifying a 17 cM interval. This result suggests a new gene localization in the proximal Xp region. In numerous families with non-specific X-linked mental retardation (MRX), the corresponding gene has been localized to the paracentromeric region in which a low recombination rate impairs the precision of mapping. 58 refs., 3 figs., 5 tabs.

Feldman, D; Altman, R

1985-01-01

The effects of a teacher personality construct (abstract vs. concrete conceptual system) and two pupil variables (race, school behavior) on 454 regular classroom teachers' attitudes toward mainstreaming were determined. Following administration of the Conceptual Systems Test, teachers were randomly assigned a profile of a mildly mentally retarded student that held pupil IQ and school achievement constant while varying pupil's race and school behavior. Subjects responded on an integration inventory comprised of three subscales: social-psychological classroom environment, self-actualization, and classroom cohesiveness. Results revealed a significant main effect on the behavior variable and a significant Personality X Race interaction on all inventory dimensions, suggesting that these teachers perceived maladaptive behavior of mainstreamed retarded students as a significant threat to a conducive instructional atmosphere and the capability of nonretarded students to achieve to their potential. These results have implications for inservice training for teachers based on the pupil race and teacher conceptual system findings.

Epigenetic Histone Deacetylation Inhibition Prevents the Development and Persistence of Temporal Lobe Epilepsy.

Science.gov (United States)

Reddy, Sandesh D; Clossen, Bryan L; Reddy, Doodipala Samba

2018-01-01

Epilepsy is a chronic brain disease characterized by repeated unprovoked seizures. Currently, no drug therapy exists for curing epilepsy or disease modification in people at risk. Despite several emerging mechanisms, there have been few studies of epigenetic signaling in epileptogenesis, the process whereby a normal brain becomes progressively epileptic because of precipitating factors. Here, we report a novel role of histone deacetylation as a critical epigenetic mechanism in epileptogenesis. Experiments were conducted using the histone deacetylase (HDAC) inhibitor sodium butyrate in the hippocampus kindling model of temporal lobe epilepsy (TLE), a classic model heavily used to approve drugs for treatment of epilepsy. Daily treatment with butyrate significantly inhibited HDAC activity and retarded the development of limbic epileptogenesis without affecting after-discharge signal. HDAC inhibition markedly impaired the persistence of seizure expression many weeks after epilepsy development. Moreover, subchronic HDAC inhibition for 2 weeks resulted in a striking retardation of epileptogenesis. HDAC inhibition, unexpectedly, also showed erasure of the epileptogenic state in epileptic animals. Finally, butyrate-treated animals exhibited a powerful reduction in mossy fiber sprouting, a morphologic index of epileptogenesis. Together these results underscore that HDAC inhibition prevents the development of TLE, indicating HDAC's critical signaling role in epileptogenesis. These findings, therefore, envisage a unique novel therapy for preventing or curing epilepsy by targeting the epigenetic HDAC pathway.

The fragile x mental retardation syndrome 20 years after the FMR1 gene discovery: an expanding universe of knowledge.

Science.gov (United States)

Rousseau, François; Labelle, Yves; Bussières, Johanne; Lindsay, Carmen

2011-08-01

The fragile X mental retardation (FXMR) syndrome is one of the most frequent causes of mental retardation. Affected individuals display a wide range of additional characteristic features including behavioural and physical phenotypes, and the extent to which individuals are affected is highly variable.

The fragile X mental retardation (FXMR) syndrome is one of the most frequent causes of mental retardation. Affected individuals display a wide range of additional characteristic features including behavioural and physical phenotypes, and the extent to which individuals are affected is highly variable. For these reasons, elucidation of the pathophysiology of this disease has been an important challenge to the scientific community. 1991 marks the year of the discovery of both the FMR1 gene mutations involved in this disease, and of their dynamic nature. Although a mouse model for the disease has been available for 16 years and extensive research has been performed on the FMR1 protein (FMRP), we still understand little about how the disease develops, and no treatment has yet been shown to be effective. In this review, we summarise current knowledge on FXMR with an emphasis on the technical challenges of molecular diagnostics, on its prevalence and dynamics among populations, and on the potential of screening for FMR1 mutations.

Mental retardation in Nance-Horan syndrome: clinical and neuropsychological assessment in four families.

Science.gov (United States)

Toutain, A; Ayrault, A D; Moraine, C

1997-08-22

Nance-Horan syndrome (NHS) is a rare X-linked condition comprising congenital cataract with microcornea, distinctive dental, and evocative facial anomalies. Intellectual handicap was mentioned in seven published NHS patients. We performed a clinical study focused on psychomotor development, intellectual abilities, and behavior in 13 affected males in four NHS families, and present the results of a neuropsychological evaluation in 7 of them. Our study confirms that mental retardation (MR) can be a major component of the NHS. Combining our data with those from the literature leads to a frequency of MR in NHS of around 30%. In most cases, MR is mild or moderate (80%) and not associated with motor delay. Conversely, a profound mental handicap associated with autistic traits may be observed. MR has intra- and inter-familial variability but does not appear to be expressed in carriers. Awareness of MR in NHS may be of importance in the management of the patients, especially in terms of education. Cloning and characterization of the gene and analysis of mutations will be an important step towards understanding the molecular basis of mental deficiency in NHS, and in delineation from the other XLMR conditions at Xp22.

Stigma of epilepsy.

Bandstra, Nancy F; Camfield, Carol S; Camfield, Peter R

Epilepsy directly affects 50 million people worldwide. Most can achieve excellent seizure control; however, people living with epilepsy continue to suffer from enacted or perceived stigma that is based on myths, misconceptions and misunderstandings that have persisted for thousands of years. This paper reviews the frequency and nature of stigma toward epilepsy. Significant negative attitudes prevail in the adolescent and adult public worldwide leading to loneliness and social avoidance both in school and in the workplace. People with epilepsy are often wrongly viewed as having mental health and antisocial issues and as being potentially violent toward others. Twenty-five percent of adults having epilepsy describe social stigma as a result of their epilepsy. They fear rejection and often feel shame or loneliness from this diagnosis. The psychosocial and social impact of epilepsy is significant. Yet few specific interventions have been demonstrated to alter this perception. The effect on public education is primarily short-term, while change over the long-term in attitudes and inaccurate beliefs have not presently been proven effective. School education programming demonstrates improved knowledge and attitude a month after a classroom intervention, but persisting change over a longer period of time has not been evaluated. In-depth adult psycho-educational programs for adults with epilepsy improves knowledge, coping skills and level of felt stigma. However these gains have not demonstrated persistence over time. Myths, misconceptions and misunderstandings about epilepsy continue and programs aimed at increasing knowledge and reducing negative public attitudes should be enhanced.

Deletions at 16p13.11 are associated with schizophrenia, mental retardation, and most recently idiopathic generalized epilepsy. To evaluate the role of 16p13.11 deletions, as well as other structural variation, in epilepsy disorders, we used genome-wide screens to identify copy number variation in 3812 patients with a diverse spectrum of epilepsy syndromes and in 1299 neurologically-normal controls. Large deletions (> 100 kb) at 16p13.11 were observed in 23 patients, whereas no control had a deletion greater than 16 kb. Patients, even those with identically sized 16p13.11 deletions, presented with highly variable epilepsy phenotypes. For a subset of patients with a 16p13.11 deletion, we show a consistent reduction of expression for included genes, suggesting that haploinsufficiency might contribute to pathogenicity. We also investigated another possible mechanism of pathogenicity by using hybridization-based capture and next-generation sequencing of the homologous chromosome for ten 16p13.11-deletion patients to look for unmasked recessive mutations. Follow-up genotyping of suggestive polymorphisms failed to identify any convincing recessive-acting mutations in the homologous interval corresponding to the deletion. The observation that two of the 16p13.11 deletions were larger than 2 Mb in size led us to screen for other large deletions. We found 12 additional genomic regions harboring deletions > 2 Mb in epilepsy patients, and none in controls. Additional evaluation is needed to characterize the role of these exceedingly large, non-locus-specific deletions in epilepsy. Collectively, these data implicate 16p13.11 and possibly other large deletions as risk factors for a wide range of epilepsy disorders, and they appear to point toward haploinsufficiency as a contributor to the pathogenicity of deletions.

Mentally retarded clients (N = 131) placed during a 2-year period from either an independent living or competitive employment training program were evaluated as to placement success. Thirteen percent returned to the training program. Successful independent living placement was related to intelligence and demonstrated skills in symbolic operations, personal maintenance, clothing care and use, socially appropriate behavior, and functional academics. Successful employment was related to sensorimotor, visual-auditory processing, language, and symbolic-operations skills. Major reasons for returning from a job to the competitive employment training program included inappropriate behavior or need for more training; returning from community living placement was related to money management, apartment cleanliness, social behavior, and meal preparation.

To evaluate the psychological state of children with epilepsy and analyze its influencing factors. The Mental Health Scale for Child and Adolescent was used to survey 113 children with epilepsy and 114 normal children to evaluate and compare their psychological state. Questionnaires were used to investigate the general status of all subjects and the disease condition and treatment of children with epilepsy. The possible influencing factors for the psychological state of children with epilepsy were analyzed. The mental health status of children with epilepsy was poorer than that of normal children in cognition, thinking, emotion, will-behavior, and personality traits (Pchildren with epilepsy. There is a wider range of psychological health problems in children with epilepsy than in normal children. Poor family living environment, poor seizure control, and use of many antiepileptic drugs are the risk factors affecting the psychological state of children with epilepsy. Improving family living environment, controlling seizures, and monotherapy help to improve the psychological state of children with epilepsy.

Methylmercury (MeHg) is a developmental neurotoxicant; exposure results principally from consumption of seafood contaminated by mercury (Hg). In this analysis, the burden of mental retardation (MR) associated with methylmercury exposure in the 2000 U.S. birth cohort is estimated, and the portion of this burden attributable to mercury (Hg) emissions from coal-fired power plants is identified. The aggregate loss in cognition associated with MeHg exposure in the 2000 U.S. birth cohort was estimated using two previously published dose-response models that relate increases in cord blood Hg concentrations with decrements in IQ. MeHg exposure was assumed not to be correlated with native cognitive ability. Previously published estimates were used to estimate economic costs of MR caused by MeHg. Downward shifts in IQ resulting from prenatal exposure to MeHg of anthropogenic origin are associated with 1,566 excess cases of MR annually (range: 376-14,293). This represents 3.2% of MR cases in the US (range: 0.8%-29.2%). The MR costs associated with decreases in IQ in these children amount to $2.0 billion/year (range: $0.5-17.9 billion). Hg from American power plants accounts for 231 of the excess MR cases year (range: 28-2,109), or 0.5% (range: 0.06%-4.3%) of all MR. These cases cost $289 million (range: $35 million-2.6 billion). Toxic injury to the fetal brain caused by Hg emitted from coal-fired power plants exacts a significant human and economic toll on American children.

Heavy alcohol consumption has multiple negative consequences for people with epilepsy such as precipitation of seizure, exacerbation of seizure, poor seizure control, increased side effects of antiepileptic drugs, noncompliance to antiepileptic drugs, alcohol withdrawal seizures, long-term hospital admission, status epilepticus, sudden unexpected death, and premature mortality. Methods: An institution-based cross sectional study was conducted from April 15, 2014 to May 15, 2014 with the aim of assessing prevalence of alcohol use disorders and associated factors among people with epilepsy attending Amanuel Mental Specialized Hospital, Addis Ababa, Ethiopia. A total of 413 randomly selected epileptic patients were included in this study. Data were structured using the 10-item Alcohol Use Disorders Identification questionnaire. Data were analyzed using SPSS Version 20. Bivariate and multivariate logistic regression analyses were performed to study the association, and variables with P-value <0.05 were considered as having a statistically significant association at 95% confidence interval. Results: A total of 423 study participants were selected, of whom 413 completely filled the questionnaire making the response rate 97.6%. The mean age of the respondents was 31.9 years with standard deviation of ±10.97, and 248 (60% were males. The prevalence of alcohol use disorder was 17.4%.

Motopsin (PRSS12) is a mosaic protease expressed in the central nervous system. Truncation of the human motopsin gene causes nonsyndromic mental retardation. Understanding the enzymatic properties and localization of motopsin protein in the central nervous system will help identify the molecular mechanism by which the loss of motopsin function causes mental retardation. Recombinant motopsin showed amidolytic activity against the synthetic substrate benzyloxycarbonyl-l-phenylalanyl-l-arginine 4-methyl-coumaryl-7-amide. Motopsin activated the single-chain tissue plasminogen activator precursor and exhibited gelatinolytic activity. This enzymatic activity was inhibited by typical serine protease inhibitors such as aprotinin, leupeptin, and (4-amidinophenyl) methanesulfonyl fluoride. Immunocytochemistry using anti-motopsin IgG revealed that both human and mouse motopsin proteins were distributed in discrete puncta along the dendrites and soma as well as axons in cultured hippocampal neurons. In the limbic system, including the cingulate and hippocampal pyramidal neurons and piriform cortex, high level of motopsin protein was expressed at postnatal day 10, but a very low level at 10-week-old mice. Motopsin and tissue plasminogen activator were co-expressed in the cingulate pyramidal neurons at postnatal day 10 and were distributed along dendrites of cultured pyramidal neurons. In cranial nuclei, a moderate level of motopsin protein was detected independently on the developmental stage. Our results suggest that motopsin has multiple functions, such as axon outgrowth, arranging perineuronal environment, and maintaining neuronal plasticity, partly in coordination with other proteases including tissue plasminogen activator.

Behavioral management of patients forms one of the foremost components of pediatric dental treatment. Some children readily cooperate with dental treatment, while others require general anesthesia as a part of treatment protocol for carrying out various dental procedures. Hence, we evaluated the pediatric patients with and without mental retardation, who underwent dental treatment under general anesthesia. The present study analyzed the record of 480 pediatric patients reporting in the department of pedodontics from 2008 to 2014. Analysis of the records of the patients who underwent dental treatment under general anesthesia was done and all the patients were divided into two study groups depending upon their mental level. For the purpose of evaluation, the patients were also grouped according to their age; 4 to 7 years, 8 to 12 years, and 13 to 18 years. Measurement of decayed, missing, and filled teeth and scores for both deciduous and permanent dentition was done before and after the commencement of the dental treatment. Chi-square test and independent t-test were used for evaluating the level of significance. While comparing the patients in the two groups, maximum number of patients is present in the age group of 13 to 18 years. While comparing the indices' score between the two study groups in various age intervals, no statistically significant results were obtained. Restorative treatment and dental extractions were the most common dental treatments that were seen at a higher frequency in the intellectual disability study group. In patients with mental retardation, a higher frequency of restorative treatment and extractions occurs as compared to healthy subjects of similar age group. Therefore, they require special attention regarding maintenance of their oral health. Special attention should be given for maintaining the oral health of patients with special health care needs as compared to their physically and mentally normal counterparts.

Fragile X syndrome, the most common form of inherited mental retardation, is caused by the absence of the RNA-binding protein fragile X mental retardation protein (FMRP). FMRP regulates local protein synthesis in dendritic spines. Dopamine (DA) is involved in the modulation of synaptic plasticity. Activation of DA receptors can regulate higher brain functions in a protein synthesis-dependent manner. Our recent study has shown that FMRP acts as a key messenger for DA modulation in forebrain ne...

He presents with mental retardation, emotional liability, and strabismus, without any other significant dysmorphies. There are brain anomalies characterised by corpus callosum, uvula, nodule and cerebellum pyramid hypoplasias, besides arachnoid cysts in the occipital region. He had seizures refractory to pharmacotherapy and long period of confusional status with or without a motor component. The authors recognised that the EEG pattern was not fixed but changed over time, specially for bursts of slow waves with great amplitude accompanied or not by sharp components, and bursts of theta waves sharply contoured. Previously, epilepsy solely has been assigned to region 20q13. However, the important structural cerebral alterations present in our case has not been reported associated to such chromosomal abnormality and may indicate possible new chromosomal sites where such atypical neurological characteristics could be mapped.

Full Text Available PKU is the rare single-gene disease belonging to disturbance of metabolism of the amino acids, which in its own basics halved the mutated gene, whose leaning at the 12-chromosome charge for the synthesis of phenylalanine hydroxylase, turning on phenylalanine into tyrosine. Enzyme block usually leads to the accumulation of a toxic substrate and/or the deficient synthesis of a product needed for normal body function. In PKU there is a toxic accumulation of phenylalanine behind the deficient enzyme, phenylalanine hydrоxylase. The symptoms are: lighten hare, blue eyes, lithe pigmented skin, convulsion, mental retardation, low level of adrenalin caused for the lack of tyrosine, the urine have a specific smell of rats or gab.Inheritance of disease become in autosomal recessive way which always become possibility to stay hidden in the family and to inherit from knee to knee without manifestation of its own phenotype.The only therapy that successfully avoids the causes of this disease is phenylalanine-restricted diet. Today we have some affords for improvement of gene therapy, which can help us for determination to these disease. The success of the therapy depends from timing of the right detection also diagnostics all trough equivalent therapy which can successfully interrupt the new forms of mental retardation and other symptoms.

Proximal 4p deletion syndrome is characterized clinically by mental retardation, minor dysmorphic facial features, and is occasionally complicated with epilepsy. More than 20 cases of proximal 4p deletion syndrome have been reported, but the causative gene(s) remain elusive. We describe here a 2-year-old female patient with a common manifestation of proximal 4p deletion syndrome and infantile epileptic encephalopathy possessing a de novo balanced translocation t(4;13)(p15.2;q12.13). The patient was diagnosed as infantile spasms at 9 months of age. She presented with dysmorphic facial features and global developmental delay, compatible with proximal 4p deletion syndrome. Using fluorescence in situ hybridization, we determined the translocation breakpoint at 4p15.2 to be within RBPJ. RBPJ is a transcription factor in the Notch/RBPJ signaling pathway, playing a crucial role in the developing human brain, and particularly telencephalon development. Our findings, combined with those of previous studies, strongly suggest that RBPJ is causative for proximal 4p deletion syndrome and epilepsy in this case.

[Ethnographic study of neurological and mental diseases among the Uru-Chipaya peoples of the Andean Altiplano].

Science.gov (United States)

Carod-Artal, F J; Vázquez-Cabrera, C B

The Uru-Chipaya people are an ethnic group of about 2,500 people, descendants of primitive Andean cultures. Their isolation (they live at an altitude of 4,000 metres in southern Bolivia), their non-written language (Chipaya-Puquina) and their traditional way of life, clothing and customs, which are similar to those used for thousands of years, make this an unusual culture. The aim of our work was to carry out an ethnographic study of the neurological diseases experienced by these people, the way they conceive such disorders and their therapeutic approaches to them. An ethnographic field study was conducted in June 2004. A structured interview was held with a yatiri, or Chipaya healer, to allow classification of the neurological or mental diseases. Epilepsy (tukuri) is interpreted as being a consequence of an evil spirit entering through the nose. Treatment consists in drinking an infusion containing dried powdered butterfly (jesko), birds or curupancho. Achamixi (headache) is common and is treated by drinking the yatiri's fermented urine, herb tea made from the chachacoma plant and by blowing, which is done by the yatiri over the patient's head. Fright, the symptoms of which are similar to those of a post-traumatic stress disorder, is treated by a wilancha, that is, the ritual sacrifice of a llama offered to the Pachamama. Sadness, the cultural equivalent to depression, is treated with infusions made from ayrampo, a plant found in the Andean Altiplano. Psychosis (sumsu), which is treated by means of a wilancha, and mental retardation/static encephalopathy (pustkis), which are considered to be a result of a fright suffered by the mother during pregnancy, also exist. No mention was made of the existence of extrapyramidal or vascular pathologies. The cultural equivalents of certain neurological pathologies (headache, epilepsy, mental retardation, anxiety and depression) are present in this ancestral culture.

Fragile X mental retardation protein: A paradigm for translational control by RNA-binding proteins.

Science.gov (United States)

Chen, Eileen; Joseph, Simpson

2015-07-01

Translational control is a common mechanism used to regulate gene expression and occur in bacteria to mammals. Typically in translational control, an RNA-binding protein binds to a unique sequence in the mRNA to regulate protein synthesis by the ribosomes. Alternatively, a protein may bind to or modify a translation factor to globally regulate protein synthesis by the cell. Here, we review translational control by the fragile X mental retardation protein (FMRP), the absence of which causes the neurological disease, fragile X syndrome (FXS).

This article reports on a research study done in Katutura Township, near Windhoek. A qualitative, exploratory, descriptive and contextual design was followed to answer the research question investigating experiences of mothers caring for mentally retarded children at home. Phenomenological interviews were conducted with a purposefully selected sample of twelve mothers. The meaning of their experiences was analysed by using Teschxs method (1990 in Creswell, 1994:155) of analysing qualitative data. The results indicated various emotions and challenges experienced by these mothers during the care of their children. Feelings of shock, despondency and sadness dominated the early stages when the retarded children were still young. During later years, as the children were growing up, the mothers felt shame, fear, frustration, anger, disappointment and worry. However, acceptance followed, as the children grew older. Stigma seemed to affect all the respondents. Support in any form or lack thereof seemed to be the decisive factor-positioning mothers along a continuum of two extremes, namely despairing isolation and integrated happiness. Recommendations were made regarding the improvement of heath care services and education of the mothers and their families.

Conclusion: Theory of mind development of mental retarded students varies based on that type of task being used to assess. In total, the claim of Theory-Theory approach, that says theory of mind development is on the basis of necessary processes, could be accepted. Also those theories which are based on cultural-social approaches calming that experience with other people causes development of mind understanding need to be more examined.

Rett syndrome (RTT) is a severe neurodevelopmental disorder caused, in most classic cases, by mutations in the X-linked methyl-CpG-binding protein 2 gene (MECP2). A large degree of phenotypic variation has been observed in patients with RTT, both those with and without MECP2 mutations. We describe a family consisting of a proband with a phenotype that showed considerable overlap with that of RTT, her identical twin sister with autistic disorder and mild-to-moderate intellectual disability, and a brother with profound intellectual disability and seizures. No pathogenic MECP2 mutations were found in this family, and the Xq28 region that contains the MECP2 gene was not shared by the affected siblings. Three other candidate regions were identified by microsatellite mapping, including 10.3 Mb at Xp22.31-pter between Xpter and DXS1135, 19.7 Mb at Xp22.12-p22.11 between DXS1135 and DXS1214, and 16.4 Mb at Xq21.33 between DXS1196 and DXS1191. The ARX and CDKL5 genes, both of which are located within the Xp22 region, were sequenced in the affected family members, and a deletion of nucleotide 183 of the coding sequence (c.183delT) was identified in CDKL5 in the affected family members. In a screen of 44 RTT cases, a single splice-site mutation, IVS13-1G→A, was identified in a girl with a severe phenotype overlapping RTT. In the mouse brain, Cdkl5 expression overlaps—but is not identical to—that of Mecp2, and its expression is unaffected by the loss of Mecp2. These findings confirm CDKL5 as another locus associated with epilepsy and X-linked mental retardation. These results also suggest that mutations in CDKL5 can lead to a clinical phenotype that overlaps RTT. However, it remains to be determined whether CDKL5 mutations are more prevalent in specific clinical subgroups of RTT or in other clinical presentations. PMID:15492925

Although "intellectual disability" has widely replaced the term "mental retardation", the debate as to whether this entity should be conceptualized as a health condition or as a disability has intensified as the revision of the World Health Organization (WHO)'s International Classification of Diseases (ICD) advances. Defining intellectual disability as a health condition is central to retaining it in ICD, with significant implications for health policy and access to health services. This paper presents the consensus reached to date by the WHO ICD Working Group on the Classification of Intellectual Disabilities. Literature reviews were conducted and a mixed qualitative approach was followed in a series of meetings to produce consensus-based recommendations combining prior expert knowledge and available evidence. The Working Group proposes replacing mental retardation with intellectual developmental disorders, defined as "a group of developmental conditions characterized by significant impairment of cognitive functions, which are associated with limitations of learning, adaptive behaviour and skills". The Working Group further advises that intellectual developmental disorders be incorporated in the larger grouping (parent category) of neurodevelopmental disorders, that current subcategories based on clinical severity (i.e., mild, moderate, severe, profound) be continued, and that problem behaviours be removed from the core classification structure of intellectual developmental disorders and instead described as associated features.

Psychiatric and behavioral comorbidities in epilepsy: A critical reappraisal.

Science.gov (United States)

Berg, Anne T; Altalib, Hamada H; Devinsky, Orrin

2017-07-01

Psychiatric and behavioral disorders are important aspects of epilepsy and have received increasing attention in the last several years. The literature upon which most of the field relies contains some biases that must be carefully examined and resolved in future studies. First, in the pediatric epilepsy literature, many reports find that children with epilepsy have high levels of behavioral and psychiatric disorders when compared to appropriate controls. Most of these studies rely on parent-proxy completed instruments to assess these behavioral endpoints. Parents' reports are not objective but reflect parents' reactions and emotions. Increasing evidence suggests inherent biases in proxy reports and highlights the need to assess children directly. Second, periictal phenomena may be mischaracterized as underlying mood disorders. Third, many studies report elevated levels of psychiatric morbidity before and after the diagnosis of epilepsy, suggesting an inherent relation between the two types of disorders. Psychogenic nonepileptic seizures, while widely recognized as posing a diagnostic dilemma in the clinic, may account for some of these research findings. Diagnostic errors between epilepsy and psychogenic nonepileptic seizures need careful consideration when evaluating studies demonstrating associations between psychiatric disorders and epilepsy or poorer seizure control in association with psychiatric disorders in people who have epilepsy. Mental health concerns are important for everyone. An accurate, undistorted understanding of the relation between mental health disorders and epilepsy is essential to ensure appropriate therapy and to avoid unnecessary and potentially harmful treatments and common misconceptions.

Mental retardation (MR), defined as an IQ below 70, is a frequent cause of consultation in paediatrics. To evaluate the yield of brain MRI in the diagnostic work-up of unexplained MR in children. Patients and methods: The MRI features and clinical data of 100 patients (age 1-18 years) affected with non-progressive MR of unknown origin were compared to an age-matched control group (n=100). Two radiologists conducted an independent review of the MRI scans. Univariate and multivariate analyses showed a higher incidence of brain anomalies in the MR group than in the control group (53 vs 17, OR=5.7 [2.9-11.1]), for signal abnormalities within the periventricular white matter (OR=20.3 [2.6-155.3]), lateral ventricular dilatation (OR=15.6 [2.0-124]), mild corpus callosum abnormalities (shortness, atrophy) (OR=6.8 [1.8-25.6]) and subtle cerebellar abnormalities, including fissure enlargement (OR=5.2 [1.1-26.2]). The diagnostic value of MRI abnormalities was considered good in 5% of patients (Alexander disease n=1, diffuse cortical malformation n=1, leukomalacia n=1, vermian agenesis n=1, commissural agenesis n=1), and weak in 48% of patients, in whom non-specific abnormalities did not lead to a diagnosis. Some clinical features resulted in a significantly higher percentage of abnormal MRI scans: abnormal neurological examination (82% vs 47%, P=0.008), abnormal skull circumference (66% vs 49%, P=0.04). Motor delay was associated with cerebellar abnormalities (P=0.01). (orig.)

+2.71 LOD score at zero recombination is not sufficient for establishing linkage between X-linked mental retardation and X-chromosome markers

Energy Technology Data Exchange (ETDEWEB)

Robledo, R.; Melis, P.; Siniscalco, M. [and others

1996-07-12

Nonspecific X-linked mental retardation (MRX) is the denomination attributed to the familial type of mental retardation compatible with X-linked inheritance but lacking specific phenotypic manifestations. It is thus to be expected that families falling under such broad definition are genetically heterogeneous in the sense that they may be due to different types of mutations occurring, most probably, at distinct X-chromosome loci. To facilitate a genetic classification of these conditions, the Nomenclature Committee of the Eleventh Human Gene Mapping Workshop proposed to assign a unique MRX-serial number to each family where evidence of linkage with one or more X-chromosome markers had been established with a LOD score of at least +2 at zero recombination. This letter is meant to emphasize the inadequacy of this criterion for a large pedigree where the segregation of the disease has been evaluated against the haplotype constitution of the entire X-chromosome carrying the mutation in question. 12 refs., 2 figs., 1 tab.

Mental and behavioral disorders among adults with Usher syndrome have been discussed and reported in some case studies but no research has been reported on children with Usher syndrome. This article investigates the prevalence and characteristics of mental and behavioral disorders among 26 children, 3-17 years of age, with Usher syndrome. Six of the 26 children were diagnosed with a mental or behavioral disorder (1 with schizophrenia and mild mental retardation, 1 with atypical autism and severe mental retardation, 1 with atypical autism and mild mental retardation, 1 with mild mental retardation, and 2 with conduct disorder). Another 3 children had had a mental or behavioral disorder previously in their childhood. Even though vision impairment first manifests in late childhood, some children with Usher syndrome seem to develop mental and behavioral disorders during childhood. The aetiology and treatment of mental and behavioral disorders among children with Usher syndrome are discussed. Children with Usher syndrome and their parents may need clinical support during early childhood to prevent development of mental and behavioral disorders.

Nickels, Katherine C.; Grossardt, Brandon R.; Wirrell, Elaine C.

2013-01-01

Purpose Epilepsy is a common childhood neurologic disorder, affecting 0.5 to1% of children. Increased mortality occurs due to progression of underlying disease, seizure-related accidents, suicide, status epilepticus, aspiration during seizures, and sudden unexplained death in epilepsy (SUDEP). Previous studies show mortality rates of 2.7 to 6.9 per 1000 person-years (Berg et al., 2004, Sillanpaa & Shinnar, 2010). Potential risk factors include poor seizure control, intractable epilepsy, status epilepticus, tonic-clonic seizures, mental retardation, and remote symptomatic cause of epilepsy (Berg et al., 2004, Sillanpaa & Shinnar, 2010, Walczak et al., 2001). Few population-based studies of mortality and SUDEP in childhood-onset epilepsy have been published. The purpose of this study is to report mortality and SUDEP from a 30 year population-based cohort of children with epilepsy. Methods The Medical Diagnostic Index of the Rochester Epidemiology Project was searched for all codes related to seizure and convulsion in children living in Olmsted County, Minnesota and of ages birth through 17 years from 1980 through 2009. The medical records of these children were reviewed to identify all those with new-onset epilepsy, and to abstract other baseline and follow-up information. Potential risk factors including seizure type, epilepsy syndrome, history of status epilepticus, the presence and severity of neurologic impairment, and epilepsy outcome was reviewed. Epilepsy outcome was characterized by seizure frequency, number of anti-seizure medications (AEDs) used, and number of AEDs failed due to lack of efficacy, and epilepsy intractability at 1, 2, 3, 5, 10, 15, and 20 years after epilepsy onset. We followed all children through their most recent visit to determine vital status, cause of death, and whether autopsy was performed. Key Findings From 1980 to 2009, there were 467 children age birth through 17 years diagnosed with epilepsy while residents of Olmsted County, MN

Many animal models in different species have been developed for mental and behavioral disorders. This review presents large animals (dog, ovine, swine, horse) as potential models of this disorders. The article was based on the researches that were published in the peer-reviewed journals. Aliterature research was carried out using the PubMed database. The above issues were discussed in the several problem groups in accordance with the WHO International Statistical Classification of Diseases and Related Health Problems 10thRevision (ICD-10), in particular regarding: organic, including symptomatic, disorders; mental disorders (Alzheimer's disease and Huntington's disease, pernicious anemia and hepatic encephalopathy, epilepsy, Parkinson's disease, Creutzfeldt-Jakob disease); behavioral disorders due to psychoactive substance use (alcoholic intoxication, abuse of morphine); schizophrenia and other schizotypal disorders (puerperal psychosis); mood (affective) disorders (depressive episode); neurotic, stress-related and somatoform disorders (posttraumatic stress disorder, obsessive-compulsive disorder); behavioral syndromes associated with physiological disturbances and physical factors (anxiety disorders, anorexia nervosa, narcolepsy); mental retardation (Cohen syndrome, Down syndrome, Hunter syndrome); behavioral and emotional disorders (attention deficit hyperactivity disorder). This data indicates many large animal disorders which can be models to examine the above human mental and behavioral disorders.

2016-01-01

Full Text Available Mutation in the PCDH19 gene was first described by L.M. Dibbens et al. in 2008. Mutations in this gene are associated with epilepsy and mental retardation limited to females. The clinical manifestations that are observed in some patients with PCDH19 mutation and Dravet syndrome that is caused by mutation in the SCN1A gene include the onset of febrile and afebrile seizures in infancy, serial seizures during fever, and regression in development after the onset of seizures. Due to the fact that the two diseases have common clinical signs, it is best to test for PCDH19 mutation in patients with the clinical picture of Dravet syndrome and a negative test for SCN1A. In general, the number of scientific papers devoted to analysis and recommendations for the choice of therapy in patients with rare genetic pathology is small now. We analyzed the specific features of clinical signs and therapy in our two observed female patients aged 4 and 11 years with verified PCDH19 mutation. Both patients were noted to have severe epilepsy with febrile convulsions with the development of status epilepticus and to be unresponsive to antiepileptic therapy. The use of different antiepileptic drugs (valproate, oxcarbazepine, phenobarbital, topiramate, levetiracetam at different combinations failed to control the course of epilepsy in the 4-year-old patient whereas the 11-year-old patient who took a combination of valproic acid and benzodiazepines achieved a positive effect.

Main attack types were as follows: 12 cases with focal seizures (33.33% , 5 cases with generalized seizures (13.89% , 7 cases with spasms (19.44% and 12 cases (33.33% with mixed seizures. Mental retardation was found in 19 cases (67.86%. Among 30 cases who received brain MRI examination, all had subependymal nodules, 26 cases (86.67% were complicated with cortical and subcortical nodules, 2 cases (6.67% with subependymal giant cell astrocytoma (SEGA, one case (3.33% with pachygyria. EEG examination showed interictal epileptiform discharges in 34 cases (94.44% , including multifocal discharges in 12 patients (35.29% , generalized discharges in 8 patients (23.53% , focal discharges and hypsarrhythmia in 7 patients (20.59% respectively. Seizures were monitored in 8 patients, and the types included spasms in 4 cases, focal seizures in 3 cases, and myoclonic seizures in one case. Seventeen cases (47.22% took one single antiepileptic drug, 12 cases (33.33% took two drugs, and 7 cases (19.44% took three drugs, while one of them underwent surgical treatment. After 0.50-10 year follow-up, seizures free happened in 7 cases (19.44%, improved in 16 cases (44.44%, and invalid in 13 cases (36.11%.  Conclusions Epilepsy is the most common nervous system performance in children TSC, and most seizures begin to happen in infants. The main types of onset are partial seizures and spasms. Most of the patients get improved with antiepileptic drugs. doi: 10.3969/j.issn.1672-6731.2014.12.011

Temporal requirements of the fragile X mental retardation protein in modulating circadian clock circuit synaptic architecture

Directory of Open Access Journals (Sweden)

Cheryl L Gatto

2009-08-01

Full Text Available Loss of fragile X mental retardation 1 (FMR1 gene function is the most common cause of inherited mental retardation and autism spectrum disorders, characterized by attention disorder, hyperactivity and disruption of circadian activity cycles. Pursuit of effective intervention strategies requires determining when the FMR1 product (FMRP is required in the regulation of neuronal circuitry controlling these behaviors. In the well-characterized Drosophila disease model, loss of the highly conserved dFMRP causes circadian arrhythmicity and conspicuous abnormalities in the circadian clock circuitry. Here, a novel Sholl Analysis was used to quantify over-elaborated synaptic architecture in dfmr1-null small ventrolateral neurons (sLNvs, a key subset of clock neurons. The transgenic Gene-Switch system was employed to drive conditional neuronal dFMRP expression in the dfmr1-null mutant background in order to dissect temporal requirements within the clock circuit. Introduction of dFMRP during early brain development, including the stages of neurogenesis, neuronal fate specification and early pathfinding, provided no rescue of dfmr1 mutant phenotypes. Similarly, restoring normal dFMRP expression in the adult failed to restore circadian circuit architecture. In sharp contrast, supplying dFMRP during a transient window of very late brain development, wherein synaptogenesis and substantial subsequent synaptic reorganization (e.g. use-dependent pruning occur, provided strong morphological rescue to reestablish normal sLNvs synaptic arbors. We conclude that dFMRP plays a developmentally restricted role in sculpting synaptic architecture in these neurons that cannot be compensated for by later reintroduction of the protein at maturity.

Healthy People 2020, a national health promotion initiative, calls for increasing the proportion of U.S. adults who self-report good or better health. The Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health Scale (GHS) was identified as a reliable and valid set of items of self-reported physical and mental health to monitor these two domains across the decade. The purpose of this study was to examine the percentage of adults with an epilepsy history who met the Healthy People 2020 target for self-reported good or better health and to compare these percentages to adults with history of other common chronic conditions. Using the 2010 National Health Interview Survey, we compared and estimated the age-standardized prevalence of reporting good or better physical and mental health among adults with five selected chronic conditions including epilepsy, diabetes, heart disease, cancer, and hypertension. We examined response patterns for physical and mental health scale among adults with these five conditions. The percentages of adults with epilepsy who reported good or better physical health (52%) or mental health (54%) were significantly below the Healthy People 2020 target estimate of 80% for both outcomes. Significantly smaller percentages of adults with an epilepsy history reported good or better physical health than adults with heart disease, cancer, or hypertension. Significantly smaller percentages of adults with an epilepsy history reported good or better mental health than adults with all other four conditions. Health and social service providers can implement and enhance existing evidence-based clinical interventions and public health programs and strategies shown to improve outcomes in epilepsy. These estimates can be used to assess improvements in the Healthy People 2020 Health-Related Quality of Life and Well-Being Objective throughout the decade. Published by Elsevier Inc.

Biallelic UNC80 mutations cause infantile hypotonia with psychomotor retardation and characteristic facies 2 (IHPRF2), which is characterized by hypotonia, developmental delay (DD)/intellectual disability (ID), intrauterine growth retardation, postnatal growth retardation and characteristic facial features. We report two unrelated Chinese patients with compound heterozygous UNC80 mutations inherited from their parents, as identified by whole-exome sequencing (WES). Mutations c.3719G>A (p.W1240*)/c.4926_4937del (p.N1643_L1646del) and c.4963C>T (p.R1655C)/c.8385C>G (p.Y2795*) were identified in patient 1 and patient 2, respectively. Although both patients presented with DD/ID and hypotonia, different manifestations also occurred. Patient 1 presented with infantile hypotonia, epilepsy and hyperactivity without growth retardation, whereas patient 2 presented with persistent hypotonia, growth retardation and self-injury without epilepsy. Furthermore, we herein summarize the genotypes and phenotypes of patients with UNC80 mutations reported in the literature, revealing that IHPRF2 is a phenotypically heterogeneous disease. Common facial dysmorphisms include a thin upper lip, a tented upper lip, a triangular face, strabismus and microcephaly. To some extent, the manifestations of IHPRF2 mimic those of Angelman syndrome (AS)-like syndromes. Copyright © 2018 Elsevier B.V. All rights reserved.

The physiology of mental anorexia is very controversial. In some cases, it was described an association with injuries close to the right frontal and temporal lobes. We report the case of an anorexia associated to a partial right frontal epilepsy, fortuitously diagnosed in crisis by a PET with {sup 18}F.D.G.. Conclusions: Because of its closely relationship with the limbic system, the abnormalities touching the right frontal area could contribute to the development of dietary behaviour troubles. This case illustrates this relationship and reports in addition a per-critic PET image of partial epilepsy, that is exceptional because of the tracer kinetics. (N.C.)

We report a three-generation family manifesting a previously undescribed X-linked mental retardation syndrome. Four of the six moderately retarded males have had episodes of manic-depressive psychosis. The phenotype also includes pyramidal signs, Parkinsonian features, and macroorchidism, but there are no characteristic dysmorphic facial features. Affected males do not show fragile sites at distal Xq on cytogenetic analysis, nor do they have expansions of the CGG repeats at the FRAXA, FRAXE, or FRAXF loci. Linkage analyses were undertaken, and a maximal LOD score of 3.311 at {theta} = .0 was observed with the microsatellite marker DXS1123 in Xq28. A recombination was detected in one of the affected males with DXS1691 (Xq28), which gives the proximal boundary of the localization. No distal recombination has been detected at any of the loci tested. 31 refs., 2 figs., 2 tabs.

Gastaut, H

1984-08-01

Based on recent data on the symptomatology of epileptic seizures and the interictal behavior shown by Dostoevsky, the author considers the debate open as to whether Dostoevsky presented primary generalized epilepsy or temporal lobe epilepsy. It is concluded that the most reasonable hypothesis on this subject is an eclectic one, wherein both etiologies of epilepsy would have been present with Dostoevsky displaying both of the following: a lesion of the temporal lobe of very discreet magnitude, thus lacking mental or somatic expression in the interictal period; and a constitutional predisposition to epilepsy of sufficient magnitude to render epileptogenic this otherwise silent temporal lesion, thus leading to a practically immediate secondary generalization of each seizure.

Full Text Available Phelan-McDermid syndrome, also known as 22q13.3 deletion syndrome, is characterized by global developmental delay, absent or delayed speech, generalized hypotonia, and minor physical anomalies. The deletion typically involves the terminal band 22q13.3 and has been associated with both familial and de-novo translocations. We report the case of an 11-year-old Turkish girl with 22q13.3 deletion syndrome presenting with repeated seizures during the course of a rubella infection. We also review the clinical features of 22q13.3 deletion syndrome and emphasize the importance of considering a rare microdeletion syndrome for idiopathic mental retardation when results of a routine karyotype analysis are normal. To the best of our knowledge, this is the first reported case of a Turkish patient with isolated 22q13.3 deletion syndrome. [Cukurova Med J 2015; 40(1.000: 169-173

The ribonucleoprotein (RNP) of the influenza A virus is responsible for the transcription and replication of viral RNA in the nucleus. These processes require interplay between host factors and RNP components. Here, we report that the Fragile X mental retardation protein (FMRP) targets influenza virus RNA synthesis machinery and facilitates virus replication both in cell culture and in mice. We demonstrate that FMRP transiently associates with viral RNP and stimulates viral RNP assembly through RNA-mediated interaction with the nucleoprotein. Furthermore, the KH2 domain of FMRP mediates its association with the nucleoprotein. A point mutation (I304N) in the KH2 domain, identified from a Fragile X syndrome patient, disrupts the FMRP-nucleoprotein association and abolishes the ability of FMRP to participate in viral RNP assembly. We conclude that FMRP is a critical host factor used by influenza viruses to facilitate viral RNP assembly. Our observation reveals a mechanism of influenza virus RNA synthesis and provides insights into FMRP functions.

Human Mental Retardation (MR) is a common and highly heterogeneous pediatric disorder affecting around 3% of the general population; at least 215 X-linked MR (XLMR) conditions have been described, and mutations have been identified in 83 different genes, encoding proteins with a variety of function, such as chromatin remodeling, synaptic function, and intracellular trafficking. The small GTPases of the RAB family, which play an essential role in intracellular vesicular trafficking, have been shown to be involved in MR. We report here the identification of mutations in the small GTPase RAB39B gene in two male patients. One mutation in family X (D-23) introduced a stop codon seven amino acids after the start codon (c.21C > A; p.Y7X). A second mutation, in the MRX72 family, altered the 5' splice site (c.215+1G > A) and normal splicing. Neither instance produced a protein. Mutations segregate with the disease in the families, and in some family members intellectual disabilities were associated with autism spectrum disorder, epileptic seizures, and macrocephaly. We show that RAB39B, a novel RAB GTPase of unknown function, is a neuronal-specific protein that is localized to the Golgi compartment. Its downregulation leads to an alteration in the number and morphology of neurite growth cones and a significant reduction in presynaptic buttons, suggesting that RAB39B is required for synapse formation and maintenance. Our results demonstrate developmental and functional neuronal alteration as a consequence of downregulation of RAB39B and emphasize the critical role of vesicular trafficking in the development of neurons and human intellectual abilities.

Devender Bhalla

Full Text Available PURPOSE: Identify epilepsy-associated factors and calculate measures of impact, stigma, quality of life (QOL, knowledge-attitude-practice (KAP and treatment gap in Prey Veng, Cambodia. METHODS: This first Cambodian population-based case-control study had 96 epileptologist-confirmed epilepsy cases and 192 randomly selected matched healthy controls. Standard questionnaires, which have been used in similar settings, were used for collecting data on various parameters. Univariate and multivariate regression was done to determine odds ratios. Jacoby stigma, 31-item QOL, KAP etc were determined and so were the factors associated with them using STATA software. Treatment gap was measured using direct method. KEY FINDINGS: Multivariate analyses yielded family history of epilepsy, difficult or long delivery, other problems beside seizures (mainly mental retardation, hyperthermia, and eventful pregnancy of the subject's mother as factors associated with epilepsy. There was high frequency of seizure precipitants esp. those related to sleep. Population attributable risk (% was: family history (15.0, eventful pregnancy of subject's mother (14.5, long/difficult birth (6.5, and other problem beside seizures (20.0. Mean stigma (1.9±1.1, on a scale of 3 was mainly related to treatment efficacy. Mean QOL (5.0±1.4 on a scale of 10 was mainly related to treatment regularity. Cause or risk factor could be determined in 56% of cases. Treatment gap was 65.8%. SIGNIFICANCE: Factors in pre- and perinatal period were found to be most crucial for epilepsy risk in Cambodia which inturn provides major prevention opportunities. A global action plan for treatment, stigma reduction and improvement of QOL should be set-up in this country.

Progressive myoclonic epilepsy (PME) is rare epilepsy syndrome. Although EEG is a useful neurophysiological technique in the evaluation of epilepsy, few EEG abnormalities have been described in PME. So, how to use EEG hints to establish the suspected diagnosis of PME as soon as possible should be addressed. We presented a case with refractory myoclonic seizures, and progressive neurological deterioration, diagnosed as PME and neuronal ceroid lipofuscinosis disease by gene testing. The patient manifested with a significant regression in her speech ability and motor balance. The mini-mental state examination showed poor scores of 15/30. The magnetic resonance imaging showed diffused atrophy. Her EEG showed slow background with continuous occipital small spikes and photosensitivity. The following genetic testing with mutation in CLN6 confirmed the diagnosis and excluded the occipital epilepsy. Our case showed rare manifestations and special EEG features of PME, which may be confused with occipital epilepsy or photosensitive epilepsy. Thus, if the continuous occipital spikes and photosensitivity were presented in a patient with refractory seizures and developmental regression, PME should be considered.

Blood copper, zinc, magnesium and lead levels were determined by atomic absorption spectroscopy for 15 males and 16 female suffering from depression, 6 males and 1 female with mental retardation and 3 males and 4 females with seizure disorders. They were all under no medication and belong to low income groups. No difference in copper levels was found between the sexes in any of the groups. The levels in all the groups were significantly higher than in the normals. In depressives, males had significantly higher zinc levels than females and only female depressives had lower levels from normals. In both depressives and normals, males had higher magnesium levels than females but no group of patients had significantly different levels from normals. Lead levels were significantly higher in female depressives and for those with seizure disorders than for controls. At least one metal abnormality was found in 21 (67.7%) depressive, 5 (71.4%) of those with mental retardation and 6 (85.7%) with seizure disorders. (author)

Approximately one-third of the mutations responsible for Duchenne muscular dytrophy (DMD) do not involve gross rearrangements of the dystrophin gene. Methods for intensive mutation screening have recently been applied to this immense gene, which resulted in the identification of a number of point mutations in DMD patients, mostly translation-terminating mutations. A number of data raised the possibility that the C-terminal region of dystrophin might be involved in some cases of mental retardation associated with DMD. Using single-strand conformation analysis of products amplified by polymerase chain reaction (PCR-SSCA) to screen the terminal domains of the dystrophin gene (exons 60-79) of 20 unrelated patients with DMD or BMD, we detected two novel point mutations in two mentally retarded DMD patients: a 1-bp deletion in exon 70 (10334delC) and a 5' splice donor site alteration in intron 69 (10294 + 1G-->T). Both mutations should result in a premature translation termination of dystrophin. The possible effects on the reading frame were analyzed by the study of reverse transcripts amplified from peripheral blood lymphocytes mRNA and by the protein truncation test.

Neuronal migration disorders can now be recognised by MRI. This paper reports two families in which the mothers had subcortical laminar heterotopia and four of their children had either similar heterotopia (two girls) or severe pachygyria or lissencephaly (two boys). Laminar heterotopia was more evident on MRI T2 weighted images. The patients had mild to severe epilepsy and mental retardation depending on the extent of cortical abnormalities. In these families, subcortical laminar heterotopia, pachygyria, and lissencephaly seem to share the same X linked or autosomal dominant gene. No chromosomal abnormalities, especially of chromosome 17, could be identified. For appropriate genetic counselling of the family of a child with lissencephaly or subcortical laminar heterotopia, MRI should be performed in parents or siblings with mental retardation or epilepsy.

Among the very few diseases that can be traced back to ancient times none has stimulated human phantasy as much as epilepsy, and the many names given to epilepsy reflects the different trends of thinking on the topic over the past two and a half thousand years. The ancient Greek believed epilepsy to be a sacred disease with the body being invaded by a God. The view that demons and evil spirits rather than Gods were responsible for the disease prevailed throughout the middle ages, influenced by Christian thinking. This led people with epilepsy to be treated, as the mentally ill, with contempt and pity. Up to the latter half of the 19th century epilepsy remained an integral part of psychiatry. The concept of the epileptic personality, stating that the behaviour and consequently the seizures themselves came from a constitutional hereditary psychopathic make-up, was deeply entrenched. The process of distinguishing epilepsy from insanity began with the development of neurology as a new and independent discipline, helped by the discovery of electroencephalography EEG and potent antiepileptic drugs. It became more widely accepted that most epileptic patients have normal mental states. It was argued that the psychiatric consequences of having epilepsy depended on the existence of pathological brain lesions, side-effects of inadequate drugs and the psychological stress of living with a chronic and debilitating disease.

Full Text Available Introduction. Limited information regarding the relation between psychopathology associated with epilepsy, crime and the legal aspects thereof is available in South Africa. Objectives: The demographic, clinical and forensic profile of alleged offenders diagnosed with epilepsy and referred to the Free State Psychiatric Complex (FSPC Observation Unit from 2001 to 2006, was investigated. Design A retrospective cross-sectional study was conducted. Results: Of the 69 alleged offenders, aged 17–79 years (median 30 years, 94.2% were male, 81.2% Black, 72.5% single, and 69.9% unemployed. The median qualification was grade six. Offences were violent in nature and committed against a person in 75% of cases. A direct link between epilepsy and the alleged offences occurred in 7% of cases. Generalised epilepsy (34.8% and interictal psychosis (20.3% were the most commonly diagnosed conditions. Twenty-nine (42% alleged offenders lacked criminal responsibility and were not fit to stand trial. Most observati (79.2% diagnosed with generalised epilepsy were criminally liable and fit to stand trial. The highest rate of criminal incapacity was found among observati with interictal psychoses (85.7% and comorbid mental retardation (90%. Almost 60% of referred cases were declared as state patients by the court. Conclusion: In only 16% of cases, observati were found unaccountable because of epilepsy (automatisms or postictal confusional states. Our findings confirmed an increased prevalence of violent behaviour during seizure-free periods. This contributes to evidence that factors associated with epilepsy, rather than the epilepsy itself, play an important role in the possible increased risk of violent behaviour in people with epilepsy.

Opitz C syndrome: Trigonocephaly, mental retardation and craniofacial dysmorphism

J.A. Avina Fierro

2016-01-01

Full Text Available We describe a 4-year-old female child with a dysmorphic and neurological syndrome of trigonocephaly, mental and psychomotor retardation and dysmorphic facial features. The anomalies of the face were the following: slight upward palpebral fissures, ocular hypertelorism, depressed nasal bridge, hypoplastic nasal root, short nose with anteverted nares; small low set ears, smooth broad philtrum and thin upper lip. The patient had important cerebral anomalies with diffuse alterations in white matter that caused developmental delay with verbal and nonverbal disabilities and severe learning difficulties. This clinical presentation is compatible with the diagnosis of the Opitz C syndrome, a heterogeneous disease of multiple neurological and craniofacial abnormalities. The physical sign more detectable and notorious is the trigonocephaly that is manifested by a prominent metopic suture, but also can be distinguished the other minor facial anomalies that are found in the eyes, nose, mouth and ears that constitute the phenotype of the disorder. The neurological development was altered by the compression of the cerebral frontal lobes with narrowing of this cerebral area, producing hypotonia with muscle weakness, epileptic episodes manifested by seizures, and neurobehavioral and neurocognitive disorders. This syndrome is a very rare genetic disorder with autosomal recessive inheritance trait; our patient had no chromosomal abnormality in the usual karyotype but the fluorescence in situ hybridization (FISH technique showed a balanced translocation between the chromosomes two and eleven: t(2:11 (q32.2/q24.

Despite an extensive literature on cognitive impairments in focal and generalized epilepsy, only a few number of studies specifically explored social cognition disorders in epilepsy syndromes. The aim of our study was to investigate social cognition abilities in patients with temporal lobe epilepsy (TLE) and in patients with idiopathic generalized epilepsy (IGE). Thirty-nine patients (21 patients with TLE and 18 patients with IGE) and 21 matched healthy controls (HCs) were recruited. All subjects underwent a basic neuropsychological battery plus two experimental tasks evaluating emotion recognition from facial expression (Ekman-60-Faces test, Ek-60F) and mental state attribution (Story-based Empathy Task, SET). In particular, the latter is a newly developed task that assesses the ability to infer others' intentions (i.e., intention attribution - IA) and emotions (i.e., emotion attribution - EA) compared with a control condition of physical causality (i.e., causal inferences - CI). Compared with HCs, patients with TLE showed significantly lower performances on both social cognition tasks. In particular, all SET subconditions as well as the recognition of negative emotions were significantly impaired in patients with TLE vs. HCs. On the contrary, patients with IGE showed impairments on anger recognition only without any deficit at the SET task. Emotion recognition deficits occur in patients with epilepsy, possibly because of a global disruption of a pathway involving frontal, temporal, and limbic regions. Impairments of mental state attribution specifically characterize the neuropsychological profile of patients with TLE in the context of the in-depth temporal dysfunction typical of such patients. Impairments of socioemotional processing have to be considered as part of the neuropsychological assessment in both TLE and IGE in view of a correct management and for future therapeutic interventions.

The introduction of magnetic resonance (MR) has improved our understanding of the pathophysiology and early diagnosis of cerebral palsy (CP). The aim of this study was to evaluate types of lesions on MR in children with CP in correlations with motor development, cognitive impairment and risk factors. Twenty-two children aged 4-17 years (boys 12, girls 10) with CP diplegia - 16 and tetraplegia - 6 were studied. Routine MR images were performed in all children. Results: All patients had periventricular leukomalacia (PVL) in MR findings. In addition three different degrees of MRI lesion patterns were defined: a mild pattern (nucleus lentiformis and thalamus) moderate (nucleus lentiformis, thalamus and pericentral region)and a severe pattern (nucleus lentiformis , thalamus, pericentral region and hippocampus). Significant correlations of the MR findings with the motor development and mental retardation were found. No significant relationships between the MR findings and the etiological factors (prematurity, low birthweight, Apgar score, sepsis, seizures, pre-eclamsia , and gestational age) were noted. MR imaging is useful in the evaluation structural abnormalities in the brains in the children with spastic diplegia and tetraplegia. (author)

A new syndrome: multiple congenital abnormalities and mental retardation in two brothers.

Dundar, M; Ozdemir, S Y; Fryns, J P

2012-01-01

In this report we present two brothers with abnormal neurological development, hypotonia, short stature, pylorus stenosis, pectus excavatum, brachycephaly due to craniosynostosis, frontal bossing, depressed nasal bridge, high arched-wide palate, downslant palpebral fissures, low-set, large ears, thin upper lip and bilateral cryptorchidism. The brothers were born to a couple of second cousins and were the third and fourth pregnancies of the mother. The father, the mother and the eldest sibling were phenotypically and chromosomally normal. The clinical findings of the brothers were found to be similar. These clinical findings were compared with syndromes showing some of the symptoms, namely Apert, FG, Floating-Harbor, Shprintzen-Goldberg and Rett Syndromes. However, when the findings were detailed, we observed that they did not match completely any of the syndromes in a discernable way. The MECP2 gene mutation was analysed because of mental retardation, poor neurological evolution and large ears, but no mutation was found. So these cases are presented as a new syndrome with apparent autosomal recessive inheritance.

Objectives This exploratory study identifies barriers and facilitators to self-management to inform future epilepsy self-management interventions for persons who have epilepsy complicated by co-morbid mental health conditions and serious medical events. Methods Focus group methods were used in a series of community advisory board meetings. Analysis was conducted using a thematic, constant comparative approach aiming to describe the range of barriers and facilitators salient to participants. There were a total of 22 participants, including 8 health professionals, 9 patients with epilepsy, and 5 care partners. Mean age was 49.1 (SD = 11.0, range 32-69), 11 (50%) were female, and 11 (50%) were male. For those with epilepsy, mean years having epilepsy was 24.7 (SD = 19.9, range 1-58 years). Results Individual psychological barriers (mental illness, fatigue, and psychological distress) prominently interfered with health behaviors. Community and family barriers included stigma, lack of epilepsy knowledge, and poor social support. Facilitators included planning for seizures, learning about medications, stress management, socializing with others, and talking with other epilepsy patients. Discussion Qualitative evidence in this study suggests a linkage between social integration and positive health behaviors. Future efforts to embed patients with epilepsy and their caregivers into clinical care processes could offset barriers and enhance facilitators.

Parfene, Cristina; Stewart, Tracie L; King, Tricia Z

2009-08-01

In the first experimental study of epilepsy-based discrimination in the workplace, we examined the influence of stigmatization on the workplace outcomes of hypothetical employees who were associated with epilepsy, but who did not have epilepsy themselves (stigma by association). Participants (40 women, 16 men), acting as employers, evaluated one of six randomly assigned employee work portfolios that were identical except that the employee was either male or female and had taken leave during the past year to care for a child with either epilepsy or asthma, or for whom no leave was mentioned. They then evaluated the employee and made recommendations concerning the employee's workplace rewards (promotion, raise) and penalties (job termination). Work quality evaluation was similar across conditions. However, parents of a child with epilepsy received fewer workplace rewards and greater workplace penalties than did employees in the other conditions. Implications for mental health and antibias interventions are discussed.

Moral reasoning of Piagetian-matched retarded and nonretarded children and adolescents.

Kahn, J V

1983-09-01

The moral reasoning of four IQ/etiology groups was investigated: 19 organically abnormal moderately retarded, 19 organically abnormal mildly retarded, 19 mildly retarded due to psychosocial disadvantage, and 19 nonretarded individuals. In each group 12 Ss were preoperational and seven concrete operational. Moral reasoning was assessed by an instrument using moral dilemmas based on Kohlberg's procedures. The Slosson Intelligence Test was used to determine the IQs and mental ages of each S. Piagetian stage was determined with the standard conservation of number tasks. The findings indicated no overall significant differences between the mildly retarded and the nonretarded Ss or between the mildly retarded and the moderately retarded Ss, but differences were found between the moderately retarded and the nonretarded Ss. A significant interaction was found between the two independent variables, IQ/etiology and cognitive level. The results were discussed as supporting Zigler's development position and as damaging to Kohlberg's position.

The transition from a pediatric to adult health care system is challenging for many youths with epilepsy and their families. Recently, the Ministry of Health and Long-Term Care of the Province of Ontario, Canada, created a transition working group (TWG) to develop recommendations for the transition process for patients with epilepsy in the Province of Ontario. Herein we present an executive summary of this work. The TWG was composed of a multidisciplinary group of pediatric and adult epileptologists, psychiatrists, and family doctors from academia and from the community; neurologists from the community; nurses and social workers from pediatric and adult epilepsy programs; adolescent medicine physician specialists; a team of physicians, nurses, and social workers dedicated to patients with complex care needs; a lawyer; an occupational therapist; representatives from community epilepsy agencies; patients with epilepsy; parents of patients with epilepsy and severe intellectual disability; and project managers. Three main areas were addressed: (1) Diagnosis and Management of Seizures; 2) Mental Health and Psychosocial Needs; and 3) Financial, Community, and Legal Supports. Although there are no systematic studies on the outcomes of transition programs, the impressions of the TWG are as follows. Teenagers at risk of poor transition should be identified early. The care coordination between pediatric and adult neurologists and other specialists should begin before the actual transfer. The transition period is the ideal time to rethink the diagnosis and repeat diagnostic testing where indicated (particularly genetic testing, which now can uncover more etiologies than when patients were initially evaluated many years ago). Some screening tests should be repeated after the move to the adult system. The seven steps proposed herein may facilitate transition, thereby promoting uninterrupted and adequate care for youth with epilepsy leaving the pediatric system. Wiley

EPILEPSY IN ELDERLY PATIENTS (DIAGNOSTIC FEATURES

Directory of Open Access Journals (Sweden)

S. A. Gulyaev

2014-01-01

Full Text Available Physicians frequently consider that epilepsy is a disease in children and young adults; however, its incidence in elderly patients is not lower and commonly higher than those among children and young people. Among the causes of epilepsy in elderly patients, there is a predominance of acute and chronic cerebral circulatory disorders (50 % of all cases. Other causes of epilepsy (neurodegenerative processes, tumors, etc. are rarely encountered in the elderly. However, there is actually no real pattern of incidence of epilepsy in the elderly since the diversity and features of its clinical manifestations in these patients, as well as difficulties in describing their status make the diagnosis of the disease very hard in this category of patients. Seizures without loss of consciousness, which are especially associated with the development of transient muscle tone disorders and autonomic dysfunction, are commonly regarded as benign vertigo, autonomic or mental disorders. This study has indicated that the development of epilepsy in the elderly, which results from cerebrovascular and neurodegenerative pathology, is not a rare, but relatively common neurological disorder. By taking into account the aging tendency in economically developed countries, the increasing number of elderly patients with epilepsy is an important medical and economic problem that calls for in-depth investigation, timely diagnosis,and treatment.

The European Forum on Epilepsy Research (ERF2013), which took place in Dublin, Ireland, on May 26-29, 2013, was designed to appraise epilepsy research priorities in Europe through consultation with clinical and basic scientists as well as representatives of lay organizations and health care providers. The ultimate goal was to provide a platform to improve the lives of persons with epilepsy by influencing the political agenda of the EU. The Forum highlighted the epidemiologic, medical, and social importance of epilepsy in Europe, and addressed three separate but closely related concepts. First, possibilities were explored as to how the stigma and social burden associated with epilepsy could be reduced through targeted initiatives at EU national and regional levels. Second, ways to ensure optimal standards of care throughout Europe were specifically discussed. Finally, a need for further funding in epilepsy research within the European Horizon 2020 funding programme was communicated to politicians and policymakers participating to the forum. Research topics discussed specifically included (1) epilepsy in the developing brain; (2) novel targets for innovative diagnostics and treatment of epilepsy; (3) what is required for prevention and cure of epilepsy; and (4) epilepsy and comorbidities, with a special focus on aging and mental health. This report provides a summary of recommendations that emerged at ERF2013 about how to (1) strengthen epilepsy research, (2) reduce the treatment gap, and (3) reduce the burden and stigma associated with epilepsy. Half of the 6 million European citizens with epilepsy feel stigmatized and experience social exclusion, stressing the need for funding trans-European awareness campaigns and monitoring their impact on stigma, in line with the global commitment of the European Commission and with the recommendations made in the 2011 Written Declaration on Epilepsy. Epilepsy care has high rates of misdiagnosis and considerable variability in

Co-morbidities of epilepsy have not been well explored in the elderly. Herein, we examined mental status, mood, and sleep in elderly patients with epilepsy, compared to age and gender matched community controls without epilepsy from the Einstein Aging Study. Testing included a mental status test, the Blessed Information Memory and Concentration (BIMC) test; Prime-MD Patient Health Questionnaire (PHQ) Depression and Anxiety Modules; and Medical Outcomes Study Sleep Scale. Persons with epilepsy (n=31) had higher mean BIMC scores than controls (n=31, BIMC 6.3 vs.1.2; p<0.0001). Mean PHQ Depression scores were higher for cases than controls indicating more depressive symptoms (4.2 vs. 0.8; p=0.006); six cases (18%) and no controls met screening criteria for depression. Mean PHQ Anxiety scores were also higher for cases than controls (3.7 vs. 0.0; p=0.001). Cases demonstrated poorer sleep scores in the categories of somnolence (p=0.009) and shortness of breath/headache (p=0.021). Thus, co-morbidities of epilepsy in this elderly population included decreased mental status, a higher prevalence of depression and anxiety, and poorer sleep health when compared to age mates without epilepsy. Mental status impairment was not related to anti-epileptic medication or mood disturbance. Further investigation will explore these associations prospectively. PMID:19189862

The fragile X mental retardation protein (FMRP) is lacking or mutated in patients with the fragile X syndrome (FXS), the most frequent form of inherited intellectual disability. FMRP affects metastasis formation in a mouse model for breast cancer. Here we show that FMRP is overexpressed in human melanoma with high Breslow thickness and high Clark level. Furthermore, meta-analysis of the TCGA melanoma data revealed that high levels of FMRP expression correlate significantly with metastatic tumor tissues, risk of relapsing and disease-free survival. Reduction of FMRP in metastatic melanoma cell lines impinges on cell migration, invasion and adhesion. Next-generation sequencing in human melanoma cells revealed that FMRP regulates a large number of mRNAs involved in relevant processes of melanoma progression. Our findings suggest an association between FMRP levels and the invasive phenotype in melanoma and might open new avenues towards the discovery of novel therapeutic targets.
