Background: The need for early treatment of autism spectrum disorders (ASD) necessitates early screening. Very few tools have been prospectively tested with infants of less than 12 months of age. The PREAUT grid is based on dyadic assessment through interaction and shared emotion and showed good metrics for predicting ASD in very-high-risk infants with West syndrome.

The PréAut grid assesses this risk following WS onset by taking into account synchrony and emotion in interactions and by evaluating the baby's active desire to engage in pleasant interactions (especially the infant's early active behaviors that encourage being gazed at or kissed by the mother or to share joy with her). We followed a sample of 25 WS patients prospectively from disease onset and assessed whether the PréAut grid before 9 months, and the checklist for autism in toddlers (CHAT) at 18 and 24 months predicted autism or intellectual disability (ID) outcomes at 4 years.

Developmental studies of observational learning still remain rare and even more rare are studies documenting the capacities of low-functioning children with autism to learn by observation. In the first investigation of this question, twenty nonverbal children with autism with a developmental age of 24 and 36 months, and twenty matched typical children, were presented with an experimental box requiring that a hierarchical sequence of subgoals be performed before it could be opened.

The characterization of memory functions in individuals with autism has been the subject of numerous investigations, with widely varying conclusions. The notable differences between these studies can be attributed to variations in the age, intelligence and level of severity of the participants with autism.

Method: First, the 3 US versions of the questionnaires were translated into French by 3 French-English bilingual translators (who were native speakers), and the translations were then discussed by an expert committee to ensure that the concept explored within the French context was efficiently targeted. Second, the psychometric properties of the French version were investigated in a cross-sectional, multicentre study.
Unlabelled: Autism is the best defined category among PDD. Its high prevalence, its onset in very young children and its persistence in adulthood arise many questions about early screening and early diagnosis. The aim of the study was to identify professional best practices about screening and diagnosis of autism in order to propose clinical guidelines and actions for the future.

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.

Memory, and particularly short-term memory or "working memory" (Baddeley), is involved in language acquisition in children. We have studied short-term memory, with verbal-and non verbal tests, of 8 children suffering from developmental dysphasia compared with other ones, matched in terms of age and performance I.Q.
View Article and Find Full Text PDFThe relatively recent development of research on memory has considerably improved knowledge on the subject. The cognitive approach allowed to consider memory as a multiform phenomenon, implicating separate processes and based on independent systems. Memory presently appears as an active process, beginning to get organized as soon as the first interactions between child and environment.

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.

This epidemiological research is based on the assumption that depression in the mother during pregnancy and the first few months of the post-partum constitutes a risk factor for the onset of an early psychosis in the child. This research is a comparative study between a group of mothers with early onset psychotic children and a group of mothers with non patient children, the age and sex of the children in both groups being equally distributed.

After the analysis of its concept we show in which way the paradox helps to maintain the continuity of psychological life during the crisis. Thus impossible choices which are part of the contradiction in adolescents be avoided.

Platelet serotonin was elevated in patients. Comparative to controls, serotonin was also high in urine of autistic patients, while, on the contrary there was no difference for the urinary excretion of 5-HIAA.

Principal component analysis showed: 1) a significant correlation between basic lymphocyte mitogenic activity and the clinical symptoms opposition and hyperactivity, 2) a significant correlation between high Ig levels, high PHA stimulation responses and the main autistic symptoms (withdrawal, inaffectivity, hypoactivity, mannerism, stereotypy and negatively echolalia), 3) a significant correlation with serotonin uptake by platelets and high immunological responses. Such correlations are strongly in favor of an immunologic component in autistic disease.

In a group of 22 autistic children aged 5 to 16 years and a group of normal controls matched for age and sex, catecholamines metabolism was investigated in plasma, platelets, and urine. This investigation was part of a research project in which several biological parameters (including serotonin) were explored simultaneously in the same children. In the autistic group, epinephrine and norepinephrine were significantly elevated in plasma, while epinephrin, norepinephrine, and dopamine were significantly lower in isolated platelets.

The most significant results of these studies concerning the dopaminergic, noradrenergic and indolaminergic (serotonin, efflux, uptake) systems as well as the various enzymatic complexes are also reviewed. In the second part, the methodologic problems which arise in biochemical research in the field of autism are addressed.
