Neurobiology, diagnosis and treatment in autism

Autism is an extremely complex neurodevelopmental disorder that is expressed in a spectrum of phenotypes and is characterized by impaired reciprocal social communication and stereotyped patterns of interests and activities. Its aetiopathogenesis remains poorly understood.This exhaustive synthesis discusses various aspects:A focus on the neurobiology of autism: the candidate genes implicate an involvement of numerous brain regions and a concomitant malfunctioning of neurotransmitter, immunologic, and other mechanisms.The most incisive rehabilitation models in their original formulation and the results achieved with the same or similar protocols in Italian centres (understanding, language therapy, social skill training...)The psychopharmacologic options for the condition of autism per se and for its associated, very frequent, comorbidities.It suggests a potential influence on professional practice and enables an up-to-date approach to effective diagnosis and treatment.
