The study was conducted to compare an experimental multiaxial diagnostic system (MAS) with traditional multicategorical diagnoses in child psychiatric work. Sixteen written case histories were circulated to 21 child psychiatrists, who made diagnoses independently of one another, using two different diagnostic systems. Diagnostic reliability was measured as percentage of interrater agreement. The highest diagnostic reliability was obtained in psychotic disorders, the lowest in personality disorders. The MAS implied improved diagnostic reliability of mental retardation, somatic disorders and developmental disorders. Adjustment reaction (reactio maladaptiva) was the diagnosis most commonly used, but with varying reliability in both systems. The reliability of the socio-economic and psychosocial axes were generally high.

Twelve filicidal men were examined on a forensic psychiatric service. The majority suffered from severe mental impairments due to psychosis, neurological disorders, substance abuse, or mental retardation. Most of the filicidal acts committed by these chronically impaired men resulted from isolated explosive behavior.

The factors relevant to intractability, types of epilepsy and impairment of dexterity in patients with intractable epilepsy were studied independently in different groups of patients. The factors relevant to intractable epilepsy that were disclosed in 202 patients, who required hospitalization more than twice, were as follows: strong seizure propensity, neuropsychiatric disorders including mental deterioration of various degrees, ataxia, personality changes and psychotic episodes, intolerance to antiepileptic drugs due to acute or chronic side effects, idiosyncrasy and internal disorders, self-induced seizure, misdiagnosis and mistreatment, and breakdown of family care of patients. The types of epilepsy in 224 patients with intractable epilepsy whose seizures were not adequately controlled and recurred on a monthly basis in spite of hospitalization were classified as follows: 101 patients with localization-related epilepsies or syndromes, 106 with generalized epilepsies or syndromes, 16 with undetermined epilepsies or syndromes and one with specific syndrome. In regard to partial epilepsies, frontal lobe epilepsy and partial epilepsy with multiple foci were at least partially intractable as temporal lobe epilepsy. With respect to intractable generalized epilepsies, miscellaneous symptomatic generalized epilepsies like intractable grand mal epilepsy with progressive mental retardation in childhood were as important as Lennox-Gastaut or West syndrome though it defies classification into any established syndromes. The proposed International Classification of Epileptic Syndromes and Epilepsies was found adequate for analysis of intractable epilepsy. The disturbance of fine motor performance found in 84 patients who participated in occupational therapy was investigated by test programs comprising nine subbatteries.(ABSTRACT TRUNCATED AT 250 WORDS)

The Aberrant Behavior Checklist was used to collect data from a large United States institution for comparison with ratings previously obtained in New Zealand. A total of 531 subjects within the American facility and 937 residents of New Zealand institutions were studied. The United States data were factor analyzed using the same procedures that were employed to develop the scale in New Zealand. In addition, subscales of the Checklist were analyzed as a function of sex, age, country, and level of mental retardation. Finally, the effects of various medical conditions were analyzed. The original factor structure of the Checklist was validated for the United States sample, with a mean coefficient of congruence of .93 averaged across the five factors. Sex failed to influence subscale scores, whereas age, country, and severity of retardation significantly affected ratings. Deafness was unrelated to Checklist scores whereas cerebral palsy, epilepsy, psychosis, and psychoactive drug treatment were related.

Autism is interpreted in Piagetian terms with particular reference to the question of whether the atypical cognitive development represents an exception to the similar sequence hypothesis. Findings from relevant research applying Piaget's theory to mental retardation, psychosis, and autism are reviewed. The apparent exceptions to the hypothesis presented in autistic individuals are explained by Piaget's two-factor theory of figurative versus operative functions. Many autistic individuals show an arrest in operative functions at the sensorimotor level while continuing to progress in figurative functions. The early arrest interferes with subsequent development of higher-level conceptual, symbolic, and social skills. Questions for research are offered.

The autosomal recessive disorder homocystinuria involves, in all its subgroups, an abnormality of methionine metabolism. The metabolism of methionine has been a central focus of interest for those who propose the transmethylation hypothesis of schizophrenia. The "methionine effect," as described in the research literature, is thus a theoretical link between these two disorders. The authors review the literature and describe those cases where both have occurred in the same patient. They indicate that whereas many patients with homocystinuria have been psychotic, few have been actually labeled schizophrenic. A patient with homocystinuria, mental retardation, and episodic psychosis is described and this case is used to point to the difficulties in making a definite psychiatric diagnosis in these patients. A relationship between the two syndromes is suggested.

Although excessive population has long been a dilemma in certain areas of the world, current rates of growth present a global threat to all nations. Arguments based on economics, world peace, individual freedom, humanism and the preservation of life's amenities all point to the urgent need for programs to control birth rates. This applies to the United States also, although we have the advantage of a relatively high cultural and economic level from which to attack the problem. Modern psychiatry is increasingly committed to the Community Mental Health concept, which in part implies greater involvement with the element of the population that is socially and economically at a disadvantage. Effective treatment cannot ignore the effects on the patient of intolerable reality situations, often produced by successive unwanted pregnancies. In addition, a positive approach to family planning by psychiatrists and social workers will provide the structure needed for truly preventive psychiatry; as our knowledge of the determinants of psychosis, delinquency and mental retardation expands, selective counseling can do much to prevent these family and social tragedies. Both as world citizens and as practitioners of a profession, psychiatrists cannot afford to delay pledging their resources to the solution of so compelling a problem.

Determination of monoamine metabolites was accomplished in the spinal fluid of 22 psychotic children and in 22 sex- and almost-age-matched "normal" controls. Also, specimens from groups of mentally retarded children and children with progressive encephalopathy or meningitis were used for comparison. The psychotic children showed raised levels of homovanillic acid. Thirteen children diagnosed as autistic by Rutter's criteria showed isolated increase of this metabolite. In the group of 9 children with other psychoses, both the level of homovanillic acid and that of 5-hydroxy-indoleacetic acid was raised. The comparison with the group of "simply" mentally retarded children and results within the psychotic group revealed that the increased concentration of monoamines was not attributable to mental retardation per se.

At autopsy, 72-year-old white male with chromatin-negative Klinefelter's syndrome, mental retardation, psychotic behavior, and carcinoma of the lung was noted to have right unilateral focal cerebral and cerebellar megalencephaly with broad gyri, a cytoarchitectually abnormal cortex, and thickened cerebral vessels. Literature about the neuropathology of Klinefelter's syndrome and several cases of other chromosome aberrations (XYY and XO syndromes) are reviewed. These neuropathological changes are thought to be related to clinical manifestation.

The present paper reviews most of the research on mental retardation in Norway, published in 1970-1980. An important part of this work is represented by Hole's reports of experimental phenylketonuria (PKU) in the rat and studies on peptides and protein-associated peptide complexes in mental disturbances, including experimental studies of effects on brain function and behavior of a peptide fraction (factor 3 b 2). Among studies on diseases with mental retardation, are determinations of arylsulphatase A in cultured amniotic fluid cells and in amniotic fluid as measures of prenatal diagnosis of metachromatic leukodystrophy, reports on screening disorders of tyrosine metabolism and the occurrence of positive dye test in blind children and patients with physical and mental handicaps. Further, studies on the effects of antiepileptics on immunoglobulins are reported. In the fields of social medicine, psychology and psychiatry, only few studies have been published in international journals. Brief reports on Norwegian articles comprise studies on work and disability, social and psychological handicaps in special school pupils, psychosis in mental retardation, and some efforts to design psychological treatment programs for the mentally retarded. The majority of research on mental retardation or with relevance to this field in Norway, has either been supported by the Norwegian Council for Research on Mental Retardation, or the Norwegian Research Council for Science and the Humanities. Based on annual reports of these councils, and correspondence to centers involved in such research, we have collected reports published in the period 1970 to 1980. We have also received unpublished reports, but have chosen not to include most of them in this review, because of the difficulties for the readers to obtain these reports. The institutional and noninstitutional services for the mentally retarded in Norway have no formal connection with university or other research institutes. Nevertheless, most of the research papers have been submitted from such institutes. Most of the reports traced are in the fields of basic neurobiology, medicine, and psychology, and will be dealt with under these headings.
