Pharmacologic Treatment of Autism

Abstract

Autism is a chronic and lifelong pervasive developmental disorder for which there is yet no effective cure, and medical management remains a major challenge for clinicians. In spite of the possible similarities with conditions that have an established pharmacotherapy, and despite improvements in some associated "problematic behaviors" following the use of available medications, effective medical treatment for the core symptoms involving language and social cognition remains elusive. The purpose of the present article is to review current biologic knowledge about autism in an attempt to correlate clinical trials with known mechanisms of disease. In addition, the need for controlled studies and for the creation of homogeneous subgroups of patients based on clinical and genetic characteristics is emphasized. The application of molecular genetic investigations and pharmacogenetics in the diagnostic work-up of autistic patients can lead to more effective individualized medical care.
