Autism: A review for family physicians

Area of Science:

• Neurodevelopmental Disorders
• Pediatric Neurology
• Genetics and Autism

Background:

• Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder.
• Characterized by impairments in social interaction, communication, and restricted behaviors.
• Onset typically occurs before 36 months of age.

Purpose of the Study:

• To provide an overview of Autism Spectrum Disorder (ASD).
• To highlight diagnostic criteria and potential etiologies.
• To discuss management strategies and the role of healthcare professionals.

Main Methods:

• Diagnostic criteria based on the Diagnostic and Statistical Manual of Mental Disorders-IV-Revised.
• Review of recent neuroimaging and genetic studies.
• Discussion of clinical presentation and comorbidities.

Main Results:

• Genetics and atypical central nervous system functioning (amygdala, hippocampus) are implicated in ASD etiology.
• Language and social skill regression occurs in about one-third of cases between 15-21 months.
• Comorbidities include mental retardation, epilepsy, and learning difficulties.

Conclusions:

• While there is no cure for ASD, early intervention therapy can improve functioning.
• Psychotropic medications can manage associated behavioral issues but are secondary to behavioral interventions.
• Family physicians play a crucial role in early detection, assessment, treatment coordination, and long-term monitoring.
