The concurrence of gelastic (laughing) seizures, hypothalamic hamartoma and precocious puberty constitutes a well defined epileptic syndrome in children; moreover mental retardation, neuropsychological deterioration and behavioral disorders have been often observed in these patients. In two cases we studied by means of MRI the appearance and the site of the hamartoma (in the posterior part of the hypothalamus with extension toward the third ventricle). The EEG study was performed by means of repeated recordings, of Computed EEG Topography (CET) and of Ambulatory EEG (A-EEG): in both patients during interictal periods paroxysmal EEG discharges prevailing in temporal or fronto-temporal regions and slight abnormalities of the background activity in the same areas were detected. Laughing seizures were recorded in each patient particularly by means of A-EEG: in case 1 bursts of high-voltage activity ("theta" waves) followed by depression of the background rhythm and by irregular spike discharges located in left temporal region were observed; in patient 2 irregular generalised spike discharges followed by slow waves or by depression of the background activity were seen. The presence of local abnormalities in both patients can support the hypothesis that the cortex, especially of the temporal anterior lobe, is involved in the origin of the laughing seizures. The significance of the mechanisms of secondary generalization as regards the seriousness of the epilepsy and of the mental impairment in these patients is also suggested.

Parents of children with mental retardation have become increasingly involved in special education, including training programs to facilitate teaching at home. Although some writers have argued that families accrue generalized psychological benefits of such participation, others have cautioned that the result may be increasing the burden of child-rearing. Forty-nine families of children with mental retardation were assessed before and after a parent training program, on a variety of parent, marital, and family measures. Parents reported high satisfaction with the program and showed small but statistically significant decreases in reports of symptoms of depression, parent and family problems, overall family stress, and dissatisfaction with the family's adaptability. Family characteristics were also predictive of teaching at home one year following training. The families that reported doing the least productive teaching had entered training reporting greater child-related stress and lower satisfaction with the marriage and the family.

The assessment and diagnosis of psychiatric disorders in individuals with mental retardation has been a neglected area of research. However, current research indicates that these individuals suffer from the same range of psychiatric disorders that is evident in those who are not mentally retarded. A model of assessment and diagnosis of mental illness in this population is presented that incorporates psychiatric as well as behavioral methods. The emphasis is on the comprehensive assessment of an individual's behavior, based on family history, self and informant clinical interviews, rating scales, direct observations, and an experimental analysis of the target behaviors. The model provides the basis for making differential diagnoses in terms of related psychiatric disorders and between psychiatric disorders and behavior problems. Depression and schizophrenia are used as illustrative disorders to describe the application of this model. Given the paucity of literature on the assessment and diagnosis of mental illness in individuals with mental retardation, a number of suggestions are made regarding future research and refinement of the model.

Estimates of the prevalence of comorbidity of psychiatric disorders and mental retardation in community and clinical populations range from 14.3 to 67.3 percent. A wide variety of disorders have been reported in this population, including schizophrenia, depression, and, commonly, conduct disorder. The incidence of specific disorders appears to be related to the level of retardation and the concomitant presence of seizure disorder. Accurate assessment of psychiatric disorders in this population is difficult because mentally retarded patients have poor communication skills and because most diagnostic instruments were developed for persons of normal intellectual functioning. Treatment includes educational, behavioral, and pharmacological interventions, but guidelines for safe use of psychotherapeutic drugs are needed.

A preliminary investigation of cognitive decline and depressive symptomatology is presented with older adults who have mental retardation. A series of different assessment instruments are reviewed and tested in a pilot study. A review of dementia and depression with respect to elders with mental retardation is presented to place the study in perspective. Findings reveal decreasing cognitive ability is associated with higher rates of observed depression and reported behavioral problems. Trends suggested those more elderly displayed more depressive behaviors, psychotropic medication was a common treatment, and cognitive decline was associated with lower initial intellectual levels. Dementia and depression is a complicated symptom complex to identify in aging adults with mental retardation.

The correct methodology for performing the Dexamethasone Suppression Test (DST), which has been widely studied in psychiatry for its possible utility as a laboratory test of depression, was reviewed. Factors that may invalidate the test by producing false-positive or false-negative results and current recommendations regarding using the test were discussed. Studies of the use of the DST for patients with mental retardation as well as other patients displaying atypical symptoms of depression, such as children and demented elderly persons, were reviewed.

An epidemiological community-based study of incident cases with non-provoked epileptic seizures, using case-referent methodology, was carried out to explore possible risk factors for epileptic seizures. 83 cases, between 17 and 74 years of age, of whom 67.4% had seizures of localized onset, were compared with 2 age- and sex-matched referents. Higher birth weight, movement disabilities, mental retardation, head trauma, brain tumor, depression, a period of unemployment during the previous 6 months and a history of epilepsy in relatives were more common in cases than in referent subjects. No difference was found in the socioeconomic factors investigated, except that the cases belonged to smaller households. Prematurity, home or hospital birth, parents' age at birth of cases or referents, febrile convulsions in relatives, various infections including meningitis and encephalitis, cerebrovascular disease, and alcohol, tobacco, sleep and nutritional habits were not found to be associated with development of seizures. The recent life events investigated, at home or at work, occurred as often in cases as in referents, except that significantly fewer cases had received any increase in salary during the last 6 months. The relationship between depression and development of seizures should be explored further. Moreover, the possibility of false negative results should be considered because of the sample size.

Case S.S. 59 years of age, male. At the age of 25, he had admitted to sanatorium for 7 years because of pulmonary tuberculosis. After his discharge, at the age of 45, he had started complaining of depressive mood or the idea of suicide and admitted to a mental hospital. Psychiatric diagnosis was depression and slight mental retardation. Shortly after, his depressive mood was improved, but his hypochondriac attitude was unchanged. No tendency toward dementia was proven. At the age of 54, he became enable to walk. Neurologically, pyramidal and some sort of extrapyramidal signs, dysarthria, disturbance of swallowing, fecal and urinary incontinence became apparent. Laboratory data showed scarcely any abnormality. At the age of 59, he died of bronchopneumonia. Neuropathologically, moderate degeneration of dentate nucleus, slight degeneration of pyramidal tract from medulla oblongata to spinal cord, striatum, substantia nigra were found. Neither senile plaques nor neurofibrillary changes could be seen throughout central nervous system. The most important finding is the presence of peculiar acidophilic bodies. They are round or oval, 10 approximately 20 mu in diameter and distributed in dentate nucleus, oculomotor nucleus, central grey of midbrain, superior colliculus, putamen, pallidum, subthalamic nucleus, Zona incerta, hypothalamus, Locus coeruleus, reticular formation of midbrain and pons, pontine nucleus, raphe nucleus, vestibular nucleus, inferior olive in order of number of the bodies. These bodies are scattered in so-called ground substance, and have no relations to any cell bodies or cell processes.(ABSTRACT TRUNCATED AT 250 WORDS)

Blood copper, zinc, magnesium and lead levels were determined by atomic absorption spectroscopy for 15 males and 16 females 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 belonged 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 significantly different (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.

The objective of this study is to investigate the type, importance, and incidence of hereditary diseases in patients at the National Institute of Neurology and Neurosurgery in Mexico City. A review of 6,258 files indicated that hereditary diseases represent an important problem for the Institute. Of the diseases with the highest incidences, hereditary factors have an important role in seven (epilepsy, depression, facial palsy, schizophrenia, mental retardation, migraine, and Parkinson's disease). Diseases of known monogenic etiology represent 1.5% of all the cases.
