What are the differences between developmental delay and autism?

Developmental delay and autism differ in several aspects: 1. Definition and symptoms: Developmental delay refers to a slowing of or abnormalities in the sequence of child development, potentially affecting physical growth, language, intelligence, and other areas. Autism, in contrast, is a pervasive developmental disorder characterized primarily by impairments in social interaction, communication (both verbal and nonverbal), and repetitive, stereotyped patterns of behavior. 2. Etiology: Developmental delay may be associated with factors such as genetic conditions, malnutrition, and endocrine disorders. Autism may be linked to a variety of factors including genetic predisposition, abnormal brain development, and psychosocial influences. 3. Treatment and prognosis: With active treatment, individuals with developmental delay generally have a better prognosis; treatment methods include language therapy and behavioral interventions. If left untreated, autism can affect a person's social, academic, and daily living abilities. Treatment also involves behavioral interventions and medication.
