[Early detection of risk for autism].

Although prognosis for individuals with autism has historically been poor, recent evidence points to improved outcomes with early intensive intervention. But initial contacts usually result in misplaced reassurance, followed by a series of professional consultations before a definitive diagnosis of autism is made. The long delay upsets parents and postpones an appropriate intervention. It is often possible to insure the diagnosis of autism at three. A better knowledge of the first signs of the autism, at the annual visits, and a regular monitoring of the levels of development of the communication and emotionnal engagement of the baby would allow an earlier location.
