Attention-deficit/Hyperactivity Disorder in Children: Clinical Profile and Co-morbidity

Background: To study the clinical profile and co-morbidity in Indian children with attention-deficit/hyperactivity disorder (ADHD).

Materials And Methods: A prospective analytical study of 2 years duration at the Child Guidance Clinic of a pediatric tertiary care hospital in a south Indian city using Diagnostic and statistical manual of Mental Disorders-1V based questionnaires.

Results: Of the 251 referrals, 51 (20.3%) children met the inclusion criteria for the diagnosis of ADHD. M:F ratio was 6.3:1. The mean age was 5.7 years. A majority of the children belonged to middle and lower socio-economic class and were first-born children. Most children were brought up in nuclear families. History of delayed speech and language development was commonly seen in these children. Combined type of ADHD was the most common type. At least one co-morbid diagnosis was seen in 86.3% of children, and learning disability was the most common co-morbid diagnosis. The mean IQ was 90 (SD±12).

Conclusion: Early markers of cognitive dysfunction like delayed speech, language and social and adaptive development may be a pointer towards the diagnosis of ADHD in children. Knowledge about their sociodemographic profile and other co-morbid conditions that are associated with ADHD is necessary to fully understand the magnitude of the problem and to plan effective therapy for them.
