Autism spectrum disorder does not include

• A. Seizures
• B. Repetitive behaviors
• C. Language delay
• D. Severe depressive symptoms

Answer: (D)

Autism spectrum disorder is defined by two main areas: persistent difficulties with social communication and social interaction, and restricted, repetitive patterns of behavior, interests, or activities. Within this framework, language delay is commonly seen as part of the communication challenges, and repetitive behaviors are a hallmark feature. Seizures can occur in some individuals with autism and may be associated with the condition, but they are not used to define ASD. Severe depressive symptoms, while they can occur in people with autism as a comorbidity, are not a diagnostic feature of the disorder itself. Therefore, the statement that severe depressive symptoms are not included in autism spectrum disorder aligns with its diagnostic criteria.
