[Assessment of mental states at risk of psychotic transition: validation of the French version of the CAARMS].

This article aims to present the validation study of the French version of the Comprehensive Assessment of at risk mental states (CAARMS), an interview that seeks to determine whether young adults criteria for at-risk (AR) mental states, or psychosis. We assessed 40 young subjects, 15 were considered as "prodromal" (Prd) and 10 as experiencing a first episode of psychosis (PEP) by our expert clinician at the center - centre d'évaluation des jeunes adultes et adolescents, University Hospital Centre, Paris - and 15 were healthy controls matched for age and sex. When assessed with the CAARMS, 73 % (n=11) of the prodromal subjects reached the criteria for AR mental state, four subjects did not reach the criteria for AR, nor psychosis (P) and 100 % of the PEP reached the criteria for P.

Altered semantic but not phonological verbal fluency in young help-seeking individuals with ultra high risk of psychosis.

Some of the cognitive impairments of schizophrenia are already detectable before the onset of the disease, and could help to identify individuals at higher risk of psychosis. In patients with schizophrenia, semantic verbal fluency (VF) is more impaired than phonological fluency. We investigated whether the same profile is present in young patients at Ultra High Risk of psychosis (UHR).

[Prodromal symptoms of schizophrenia].

The concept of prodromal symptoms of schizophrenia has frequently been subject to debate. Authors widely admit the existence of early specific and non-specific signs preceding the first psychotic episode; however, they have yet to clearly demonstrate their ability to predict and specify the outbreak of a psychosis. These prodromal symptoms consist of behavioral abnormalities, pseudo-neurotic signs, subtle cognitive and affective changes.

[Survey on the announcement of schizophrenia diagnosis in France].

Medical information for the general public, patients and their families is a current Public Health priority. What information can be given to a patient suffering from schizophrenia, whose understanding and judgement capacities are supposedly affected by this mental disease? In the United States, 70% of psychiatrists inform patients of schizophrenia and diagnosis of schizophreniform disorder, while in Japan less than 30% do this. The lack of information given to the general public on the disease may contribute to reinforcing the difficulty in announcing the diagnosis.
