Background: ADHD is one of the most common behaviour disorder encountered in children. It makes up for nearly 50% of the attendance in Child Psychiatry Clinics. ADHD has been described as a developmental disorder characterised by varying degrees of inattention, hyperactivity and impulsivity arising in childhood. If not treated in childhood then such children are at risk of academic failure and peer rejection. While the adolescent with ADHD who remain untreated face other risks such as increased proneness to automobile accidents, substance use and abuse and trouble with the law. Though effective drug therapy is available for treatment of ADHD the parents are resistant to medicate their children because of their concerns regarding side effects, stigma, other social factors, etc. Resultantly there is high dropout rate from treatment as has been seen in clinical trials of methylphenidate versus placebo. This study will help us understand the follow up trends of patients with ADHD especially in a setting where the treatment is provided free of cost (to all CHSS beneficiaries) and hence the effect of factors like availability and cost of health care is neutralized Aim & Objectives: 1) To study the duration of follow up of patients with ADHD. 2) To correlate duration of follow up with age at onset, gender, birth order. 3) To correlate duration of follow up with educational and occupational status of parents. 4) To correlate duration of follow up with co-morbidities (especially with specific learning disability), and level of intelligence. Material and Methods: Data will be retrieved from all the available case records of patients diagnosed with ADHD during the period of 2007 to 2013. Data will include socio-demographic details, illness profile, associated co-morbidity, Intelligence Quotient and details about follow up. Results and Discussion: Data will be analyzed and discussed in accordance with available literature.
