Attention Deficit Hyperactivity disorder (ADHD), is one of the most frequent psychiatric disorders in childhood. It has been reported that among children at school age, the prevalence of ADHD varies between 2% and 20% and prevalence of comorbidity is high. In children diagnosed with ADHD, the most common comorbid diagnosis after oppositional-defiant disease is anxiety disorder. Although ADHD is a frequently comorbid with anxiety disorders, factors associated with anxiety disorders in ADHD has not been addressed adequately. According to the results of clinical and epidemiological studies, there is a consistent and reciprocal relation between ADHD and anxiety disorders, and the rate of ADHD increases in the presence of anxiety disorders compared to community samples, and vice versa. It has also been suggested that there is an independent association between these two disorders.
Case: We will discuss diagnosis, treatment and prognosis of a 11 year old boy came to Erenkoy psychiatric and neurologic research and training hospital child and adolescent psychiatry clinic with academic problems, attention deficit, hyperactivity symptoms, free şoating anxiety, obsessions and compulsions.
Discussion: It is surprising that although ADHD and anxiety disorders are frequently comorbid, there are a few studies on this issue of their coexistence. When the adverse effects of the coexistence of these two disorders on clinical practice, treatment options, course and prognosis are taken into consideration, it becomes evident that more structured and long terms studies are required on this issue.
