The paper attempts at a general assessment of mental health conditions in Latin America. Starting from methodological considerations the author points out at the difficulties for obtaining reliable data, gathered with compatible basis and the basical hindrances for building the concepts of health and illness, and for finding indicators reflecting the real health and welfare levels. The available data are discussed, together with their significance and scope. Stress is laid upon the meaning of prevalence and assistance data, which reflect only the problems of one sector of the population. The meaning of suicide and homicide is also discussed, and their use as indicators, together with data on occident rate, is suggested. The prevalence of alcoholism, psychosis and neuroses is examined, together with their role in the procedures for assessing mental health levels. Mental retardation and epilepsy are also considered. The author examines also human, technical and physical resources and facilities devoted to mental health, as well as training of personnel in the field. On the basis of statistical figures, it is showed a general deficit in all areas. As a conclusion, the author stresses the need to pay more attention to mental health problems and proposes a series of criteria in that sense.

There is an important jeopardizing factor for all nosological classificatory systems, in general Psychiatry as well as in child Psychiatry: the lack of a universally valid basis for defining concepts of "normal" and "pathological". Both stem from social patterns, values, culture and organization. Thus, they vary widely in different countries and communities. In order to attain the much needed general nosological criteria, the starting point is to our mind, a scientific comprehensive conception of man in the midst of a social environment. Pathological phenomena are usually located either in biological, psychological or sociological domains, but they are all-pervading and affect man in the whole. Taking into account that the same can be said about children, we discuss in this paper one classificatory system proposed by Telma Reca M. D. and modified by the author. Following the gravitation of the main aethiological factors, four categories are proposed: a. Psychogenetical diseases: regular or reactive developmental disturbances; acute anxiety; neurotic traits; fully developed neurosis, and psychosomatic disturbances of neurotic origin; speech disturbances of a pure psychological nature, etc. b. Psychical disorders derived from physical diseases: acute confusional or delusional states; mental retardation; epilepsy; minimal cerebral disfunction; learning difficulties derived from injuries or/and genetic deficiencies, etc. c. Psychical disorders derived from social problems: bad nourishment, disturbed sleep, faulty or disorderly sexual behaviour; poor or disturbed performance at school or in social groups, etc. d. Disorders caused by several factors: psychotic traits; psychosis; psychopathic behaviour; lack of maturity according to chronological age; congenital personality disorders, etc.

The case findings of thirty-three children given a diagnosis of psychosis during hospitalization in the '50s and '60s were reviewed and rediagnosed in 1973. Childhood schizophrenia was the original diagnosis in 58% of the cases but was the rediagnosis in only 18% of those same cases. Chronic brain syndrome with various reactions (psychotic reaction, nonpsychotic behavioral reaction, and mental retardation and autism) was the diagnosis in 27% of the cases, originally, but was given to 67% of the cases on rediagnosis. One-third of the children originally diagnosed as psychotic were rediagnosed as nonpsychotic. Approximately two-thirds of the children were nonpsychotic according to the DeMyer-Churchill guidelines.

At the present time, neuroleptics are indicated for the treatment of acute psychotic states as well as Tourette's syndrome in children and adults. Neuroleptics may have a useful role in the attenuation of problem behaviors, such as stereotypies, hyperactivity, self-injury, and aggressive outbursts in infantile autism, pervasive developmental disorder NOS, and mental retardation, but they do not improve the underlying condition. Neuroleptics are not the agents of first choice for treatment of hyperactivity or aggression in children who do not have major developmental handicaps. Common and troublesome side effects associated with neuroleptic use in children and adolescents include sedation, extrapyramidal symptoms, and withdrawal dyskinesias; therefore, close monitoring is required. Neuroleptics should be used cautiously and only as an adjunct to other nonpharmacologic interventions.

Published cases of periodic psychosis of puberty and related papers were reviewed. The clinical picture is near-monthly recurrence of episodes of stupor or excitement lasting about 1 or 2 weeks, which are accompanied by delusion and in some cases also by hallucinations or confusion. This condition was found to occur more commonly in girls than in boys, and in half of the girls reported the episodes tended to start a few days before menses. Adolescents with mental retardation were more commonly affected, and this suggests that organic brain damage may play a role in the etiology in some cases. Short-term prognosis is usually favorable, but at long-term follow-up, nearly half of them were found to be suffering from affective or schizophrenic illness. The clinical importance of recognizing this psychosis early in the course of illness is emphasized.

The Authors describe the organization and aims of the rehabilitation institute "G. Ferrero" of Alba, Cuneo district, Italy. Afterwards they present, analyse and compare 34 items regarding patients over 14 years of age that were present on the 30 November 1978 and 1988. The most important data are: 1) a large rise in average age and stay at the institute; 2) a similar rise in the mental retardation level; 3) the lack of link between handicap level and possibility for the subject to go back to the original family; 4) a considerable increase in the subjects with psychosis or cerebropathia; 5) the poor prognosis for psychotic subjects, that are affected 10 years after and almost never succeed in going back to their original family or in finding a job; 6) big changes that changing types of patients produced in the institute's aims and in treatment, with partial renunciation to rehabilitation and development of nursing and ergotherapy.

Three cases of fragile X (fra X) have been identified in a systematic survey of 30 boys, aged 3 to 14, with infantile autism or psychotic disorders, associated with mental retardation. Only one of these children exhibited a dysmorphy characterizing the Martin-Bell syndrome. Two fra X cases fulfilled the DSM III criteria for autism; none corresponded to the Kanner's description of infantile autism. The prevalence of fra X among children with psychotic disorders (6%) is much higher than in the general population; however it is close to the prevalence observed in non psychotic mentally retarded patients. Given the inconsistency of the somatic phenotype, the screening should benefit from the recent discovery of abnormal methylation of DNA.

A cross-sectional and longitudinal epidemiological study of children institutionalised for psychiatric disorders has been carried out. The differences of discharge distribution allows to describe an entanglement of three differents logics: the medical logic: diagnostic (Emotional and conduct disorder, Mental retardation, Psychosis), etiological organic factors, associated somatic disorder. the social logic: father's occupational level and etiological environnemental factors. the institutional logic: child's age when admitted, institutional categories.

The purpose of this review has been to examine the hypothesis that the Attention Deficit Hyperactivity Disorder (ADHD), formerly also referred to as the Hyperactive Syndrome or Minimal Brain Dysfunction (MBD), is a precursor of criminality and abuse of alcohol and illicit drugs. This has been done by reviewing findings from follow-ups. Most reviewed projects suffer from methodological weakness. In most materials, few if any of the cases had ADHD according to present criteria. Some had ADHD and conduct problems. Many probably had exclusively conduct problems, but were too young to fulfill the criteria of Conduct Disorder (CD). Methodological limitations of the examined projects have been pointed out. It has been discussed how weaknesses regarding research design might have influenced the results. As a consequence of methodological shortcomings of most projects, the reviewed studies do not give definite answers. However, they show some rather convincing trends. By early adulthood, ADHD appears to remain present in at least one third of the subjects. Subjects with prior ADHD did not have more mental problems than controls in adolescence and early adulthood, provided they had normal intelligence, and no additional disabilities or mental disorders. Those with mental retardation, cerebral dysfunction or psychosis in addition to ADHD have a poor prognosis. A high percent become psychotic, and some end up in institutions. Although there seems to be an increased rate of delinquency and lawbreaking in prior hyperactives compared to controls, these differences disappear when the results are analyzed. The initially impressive differences between cases and controls are probably consequences of bias. Cases with a childhood history of conduct and educational problems have been compared to controls without a history of such problems. Thus, the reported differences are not related to ADHD. Hyperactives without conduct problems do not have an increased frequency of delinquency. Problems of conduct, CD and Antisocial Personality Disorder, but not psychosis characterize cases with a childhood history of conduct problems (with or without ADHD). In subjects with ADHD as well as conduct problems in childhood, conduct problems and not ADHD predict the prognosis, which is worse than for those with CD without ADHD. ADHD combined with delinquency indicates a high rate of subsequent lawbreaking. Usually, cases have more problems than controls with alcohol and illicit drugs, but this might be the consequence of selection of cases (subjects with school and conduct problems) and controls (subjects without such problems).(ABSTRACT TRUNCATED AT 400 WORDS)

Recent illustrations by cerebral magnetic resonance imaging of anomalies of the corpus callosum in schizophrenics have kindled renewed interest in this association. We studied 62 patients affected by the Andermann syndrome, a polymalformative familial syndrome combining frequent congenital corpus callosum agenesis, mental retardation, psychotic episodes, peripheral neuropathy, and some dysmorphic features. Twenty of 62 patients presenting with psychosis were compared with 20 nonpsychotic patients matched according to sex and age. The psychotic patients presented an atypical psychosis as defined by the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, beginning in postadolescence. No significant relationship was observed between corpus callosum agenesis and psychosis. However, a significant association between posterior fossa atrophy and psychosis was established in our study. Although there are limitations in using cross-sectional data for this purpose, the findings suggest an association between cerebellar anomalies and schizophrenialike syndrome and rule out an implication of developmental callosal defects in such psychiatric disorders.
