| Abstract |
Objectives: Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder often found to have a number of co-morbidities such as oppositional defiant disorder, learning disorders. But ICD-10 and DSM-IV do not allow for co-morbid diagnosis of autism. Despite this rule, research has documented the coexistence of both. This study focused on the prevalence of autistic features in children with ADHD. Methods: Study was conducted in the department of Psychiatry of a tertiary care hospital in India. 80 children with a diagnosis of ADHD according to DSM-IV constituted the study group. 80 typically developing children from a local school matched for age and gender constituted the control group. After obtaining the assent from children and written consent from the parents, Vanderbilt ADHD Parent Rating scale and Indian Scale for assessment of Autism (ISAA) (scale based on Childhood Autism Rating Scale- CARS) were applied. Results: Statistical analysis of the data showed that prevalence of autistic features in children with ADHD is 33.8% as compared to only 8 % in the control group and this difference is statistically significant. A strong positive correlation between severity of ADHD and presence of autistic features was also noted. Combined subtype of ADHD had the highest mean score on ISAA. ODD was a common co-morbid diagnosis in children with autistic features. Conclusions: Autistic features are quite common in children with ADHD. Presence of autistic features is correlated with greater severity of ADHD symptoms as well as with combined subtype and co-morbid ODD. |
