Autism Spectrum Disorder (ASD) is characterized by persistent deficits in social communication, nonverbal behaviors, and repetitive patterns. Early diagnosis, crucial for timely intervention, is recommended by age 14 months if developmental milestones are delayed. A neuropsychologist specializing in ASD assessments conducts comprehensive evaluations, employing various tests like ADOS-2. Pediatricians provide initial screenings, but further evaluation ensures accuracy. A diagnosis opens avenues for Individualized Education Plans (IEP), offering tailored support, including speech and occupational therapy. Behavioral interventions like Applied Behavior Analysis (ABA), psychological approaches such as Cognitive Behavioral Therapy (CBT), and medication management address specific challenges, while family counseling aids adjustment to the needs of individuals with ASD.
