The Autistic Spectrum Disorders (ASD) are characterized by an atypical 
sociability, alterations in communication, restricted interests and 
stereotypies, with adding affective and adaptative disabilities. The suicidal 
behaviors are frequently observed in the adolescents and adults with an ASD 
without intellectual deficience. However, the clinical research on the topic is 
limited and the diagnosis not assessed in the emergency units. Among the 
individual risk factors of the suicidal behavior in ASD patients, mood and 
anxiety disorders are found as well as a familial affective disorder history. 
The intimidation and the lack of socio-professional integration were also 
reported as environnemental risk factors. Laters tudies taking into account the 
cognitive characteristics would permit to investigate the suicidal phenomenology 
in ASD patients.
