[The cerebellum as a major player in motor disturbances related to Autistic Syndrome Disorders].
Autism spectrum disorders (ASD) are neurodevelopmental disorders associated with disturbances in communication, social interactions, cognition and affect. ASD are also accompanied by complex movement disorders, including ataxia. A special focus of recent research in this area is made on the striatum and the cerebellum, two structures known not only to control movement but also to be involved in cognitive functions such as memory and language. Dysfunction within the motor system may be associated with abnormal movements in ASD that are translated into ataxia, abnormal pattern of righting, gait sequencing, development of walking, and hand positioning. This line of study may generate new knowledge and understanding of motor symptoms associated with ASD and aims to deliver fresh perspectives for early diagnosis and therapeutic strategies against ASD. ⋯ The "cognitive approach" has dominated ASD research for three decades and led to the design of interventional strategies, which have yielded satisfactory results. Nevertheless, new approaches and alternative hypotheses on the aetiology and diagnosis of ASD are needed. Research focused on motor rather than psychiatric symptoms may have a greater potential to elucidate the neurobiological basis of ASD.

The progressive shifts in the legal and social contexts, along with major changes in information seeking habits with the development of the Internet, have placed patients' information at the core of medical practice. This has to be applied to the psychiatric fields as well, and to questions about how schizophrenic patients are being told their diagnosis nowadays in France. ⋯ As a conclusion, having stressed the lack of recent data about schizophrenia diagnosis disclosure in France, we suggest a new study using validated tools on a representative sample and taking into account both perceptions of psychiatrist and patient. As has been the case for other severe pathologies, we also suggest that a consensus conference take place on the subject of schizophrenia diagnostic information in order to elaborate guidelines to support this difficult disclosure.
