RESUMO
BACKGROUND: There is a recent trend of increase in diagnosis of Autism Spectrum Disorder in India. Till date, there are few retrospective and prospective Indian studies with limited sample sizes ranging from 16 to 94 children. With this background, we planned a retrospective chart review of all new cases of Autism Spectrum Disorder for a period of 1 year in our tertiary care child psychiatry centre. METHODOLOGY: Objectives of this study were to compare the sociodemographic and clinical profile of children below and above 3 years of age and between those who were self-referred versus those referred by professionals. RESULTS: Out of a total of 1957 case records, 201 children (10.3%) were diagnosed with Autism Spectrum Disorder. Male to female ratio was 4:1.2. Mean age of consultation was significantly higher in males. Seventy six percent had a comorbid disorder with Intellectual disability, Attention Deficit Hyperactivity Disorder and Epilepsy being the most common comorbidities. Most caregivers (92.5%) recognized symptoms by 3 years of age. Presenting complaint of poor social response was more prevalent in children <3 years and co-morbidities in children above 3 years. Presenting complaint of speech delay was more common in children who were referred by professionals when compared with those who were self-referred. DISCUSSION: There is a need to sensitize parents and professionals for early intervention and to standardize protocols for assessment and intervention.
