The subjects of this study were 19 children and 11 adolescents who had been
psychotic
since childhood and who satisfied DSM-III criteria for schizophrenia except for the stipulation that a "deterioration from a previous level of functioning" must have occurred. Seven subjects had had documented signs of
psychosis
before the age of 30 months. The presence of thought disorder precluded giving these 7 subjects the diagnosis of
early infantile autism
. The authors argue that only symptoms and signs, not age at onset, can define a disorder. They also emphasize that in children and adolescents, developmental issues influence the clinical presentation.

Twenty-four infantile autistic children were compared with 12 children with other kinds of childhood psychoses, 5 children with so-called minimal brain dysfunction syndrome, 5 children with attention deficit disorder, 14 children with mental retardation, and 19 normal children with regard to chromatographic profiles of urinary products that give ultraviolet absorbency at 280 nm. Six main types of chromatographic patterns emerged. Fifty-four percent of the autistic children and 17% of the children with other psychoses showed a distinct pattern that was not seen in any other cases. Only 8% of the autistic children showed the "normal" pattern seen in 95% of the normal and 93% of the mentally retarded children without
psychosis
. The ultraviolet absorbency peaks of the chromatograms possibly correspond to peptides and protein-associated peptide complexes. It is argued that these products are probably at least partly of CNS origin.

This paper is elaborated in the same order of those who developpe the idea that,
Psychosis
is pleaded as an alibi of a totalitarian reality (
Psychosis
alibi). So it may allow to disengage the evolution of the Psychiatry outside of the anti-psychiatry ideologies. The main subject of this work, is to analyse the gap between the Reality which includes the
psychosis
as a part of herself (
Psychosis
as disease). On the second hand the Reality of the
psychosis
from the psycho-pathologic point of view (delirium, hallucinations,
autism
, etc...). Considering the importance of the formal grammatical functions in the linguistic matter to site the reference to the reality according to the rules of the communication and the oral expression; so we propose a grammatical analysis. Two parts are distinguishable in this work. The first part concerns a review of languages proposed in different psychiatric "theorization" established previously about mental disorder. So it could be considered that the
psychosis
is the one who "speaks" the psychiatry. The second part concerns an abstract of the "semiotiques" studies by which we can tackle the
psychosis
with a scientific language: The Psychiatric "speaking" the
psychosis
not the opposite. This way of analyse allows to realize the modifications in the part of both protagonists in the game. By the same way, it authorizes to introduce the psychiatry from the axiomatic point of view, allowing a self-contained definition as a branch of the medicine, and disengaging his subject: The
psychosis
; as a syntactic subject.

The records of 144 patients of Child Psychiatry Units of Alsace (France), with childhood
psychosis
(CP) or pervasive developmental disorders (PDD) have been systematically screened for previous or associated pathological events. Half of the children studied have been or are still affected by severe somatic disorders, but none of the diagnostic subcategories (referring to DSM III or CFTMEA) appeared significantly more frequently affected. In our population, the severity of organic disorders was positively correlated with: the age of the mother: more severe cases were reported when the mother was younger than 20 or older than 40 at the moment of childbirth; pathological events during pregnancy; early mother-child separation during the first year of life. The most frequent associated disorders however (neonatal pathology 45% of the cases, epilepsy 17% of the cases, neurological or neurosensorial pathology 15% of the cases) were associated neither with a specific diagnostic nor with a clinical and social specific pattern. The only statistically significant correlation was found between neurological pathology and a relatively low level of cognitive and social functioning. All these results were confirmed by multivariate statistical analysis. A main component analysis integrating all quantified data concerning organic pathology was performed: it emphasizes the independence of the different pathological events reported. The factorial analysis including the clinical, diagnostical and somatic event-related data failed to show any statistical profile associating functional features of the children with any particular previous or existing somatic disorders. Our results suggest that a history of organic pathological events is frequent not only in
autistic disorders
but in any kind of PDD or early CP - associated with moderate to severe mental retardation, in most cases of our study. However, this does not demonstrate that this type of pathological events constitute the direct and unique cause of PDD and CP: the concept of the aetiology of these severe diseases must take account of other factors - such as relational disruption -, also frequently seen in these children.

Descriptions of various
psychotic
symptoms in children began to appear in the psychiatric literature at about the same time as descriptions of
psychotic
symptoms in adults. For example, Kraepelin estimated that at least 3.5 percent of his cases of dementia praecox had onsets before age 10. The construct of "childhood schizophrenia" initially emerged from attempts to classify a broad range of
psychotic
children. By the late 1940s and 1950s, the diagnosis of "childhood schizophrenia" was given to many disturbed children who today would be considered to have
infantile autism
and other developmental disabilities. In the early 1970s
infantile autism
and its variants was differentiated from schizophrenia of childhood onset. These changes were incorporated in DSM-III, which returned to the practice before 1930 of diagnosing schizophrenia in children using the same criteria as for adults, with minor allowances for differences in the manifestations of these symptoms during childhood. The studies presented in this issue of Schizophrenia Bulletin use DSM-III, DSM-III-R, or ICD-9 criteria for schizophrenia.

Many forms of psychopathology in higher animals and humans include the production of maladaptive, repetitive behaviour. Behaviour which is both repetitive and excessive in amount can be described as stereotyped whereas behaviour which represents a restriction of behavioural possibilities without excessive production can be described as perseverative. Both types of repetition can result from pathology in the neural mechanisms which control either the production of motor output or the organisation of behaviour at a higher level. A number of forms of repetitive behaviour can be induced environmentally. Confinement in adulthood results in a functional disorder which rapidly dissipates when normal conditions are restored but confinement in infancy may have a permanent effect on the organism's ability to interact in a flexible and creative way with its environment. The permanence of these disorders suggests that the environment can affect the way in which the nervous system develops. Repetitive behaviour is also a feature of mental illness including schizophrenia,
autism
, OCD, addiction and some neurological disorders including frontal lobe lesions, Tourette's syndrome and PD. In experimental studies in animals, stereotyped behaviour seems to be related mainly to excess dopaminergic activity in the basal ganglia while perserverative behaviour can be produced by lesions of the frontal lobes. It is supposed that the level of dopamine activity in the basal ganglia affects the baseline level of behavioural activation such that excess activation results in the excessive execution of the most probable response to the environment to the exclusion of other possibilities (i.e. stereotypy) while deficient activation results in the production of only a few responses which can exceed the necessary activation level (i.e. perseveration). In either case behaviour is 'stimulus-bound', being driven by only the most salient feature of the environment. The symptoms of PD result from inadequate levels of dopamine in the basal ganglia while the stimulant psychoses result from excessive availability of dopamine. The frontal lobes have a modulating effect on (i) the activation of motor activity by the basal ganglia, (ii) in the generation of self-initiated behaviour, i.e. volition, and (iii) in the neural mechanisms which permit different modes of neural function (e.g. perceiving, remembering or thinking) to be identified. Failures in these three functions could result in excessive and repetitive motor activity, stimulus-bound behaviour, the paucity of volitional and creative behaviour, and the perceptual and experiential symptoms of
psychosis
.

We report in this paper pervasive developmental disorders. They represent a rather numerous group of severe psychic diseases of early childhood, of unknown etiology. All psychic functions are disturbed: thinking, emotions and mental functioning. Different classifications of these disorders include various terms for similar clinical conditions. So, there is a dilemma whether it is a case of special nosologic entities or different clinical conditions of the same disorder.
Infantile autism
, Asperger syndrome, Rett syndrome and atypical
psychosis
are described. Although prognosis is commonly unfavourable, therapy may be very helpful.

Clinical, pathopsychological and neurophysiological studies have been carried out in 85 children with infantile autistic
psychosis
and in 38 girls with Rett's syndrome. New improved differential diagnostic criteria between these two forms of early
childhood autism
have been suggested. EEG spectral density values in alpha-1, alpha-2, beta and theta subbands are established to be their neurophysiological markers. Special attention was paid to close relationship between ontogenetic neuromorphogenesis of the brain cortical structures (e.g. physiological lysis of cortical cell populations at the age 8-30 months of the child's life) and the defect severity in the onset of illness at the same age range in patients with the studied forms of early
childhood autism
. The data obtained are discussed in terms of new approaches to understanding pathogenesis of different forms of early
childhood autism
.

The purpose of this study was to assess the relationship between
autism
and childhood
psychosis
. Fifteen children with
psychotic
symptoms were compared to 15 children with
autism
, using two observational measures, the Ritvo-Freeman Real Life Rating Scale (RLRS) and the Childhood
Autism
Rating Scale (CARS), which rate subjects on behaviors pathognomic to
autism
. In comparison to autistic persons,
psychotic
individuals were judged to have better language and social skills. In addition, autistic persons were also rated as having more difficulty adapting to new situations and appeared more "autistic-like." Overall scores on the CARS and RLRS were significantly different between the two groups, indicating that these two assessment instruments may be useful in differential diagnosis. However, 20% of the
psychotic
subjects received pervasive developmental disorder diagnoses, indicating that there may be a relationship between those two disorders.

This study examined the outcome of youth previously diagnosed with
psychotic
disorders at a public-sector tertiary care hospital. Of 95 children and adolescents retrospectively identified, follow-up information (mean interval 3.9 years) was obtained on 24 subjects with an outcome diagnosis of schizophrenia, 9 with
psychotic
mood disorders, 5 with personality disorders (antisocial or borderline), and 1 with schizo-affective disorder. The schizophrenic group was more often odd premorbidly and functioned worse at outcome, while the mood-disordered group had a shorter follow-up period and was more often anxious or dysthymic premorbidly. The personality-disordered group resembled the schizophrenics in their degree of impairment and chronicity. All three groups had high rates of family disruption, low SES, substance abuse, and chronicity, and were similar in their degree of premorbid impairment, length of prodrome, age of onset, initial diagnosis, and family psychiatric history. Misdiagnosis at onset was quite common and highlights the need for systematic longitudinal assessment of early onset
psychotic
disorders.
