ABSTRACT

In children and adolescents with intellectual disabilities, both physical and psychiatric comorbidity rates are higher than in developmentally normal children and attention deficit hyperactivity disorder and conduct disorder are among the most common psychiatric conditions. Treatment of children with intellectual disability is similar to the treatment of attention deficit hyperactivity disorder (ADHD) with developmentally normal children, but in various cases, different treatment options such as alpha-2 agonists are needed. In this report, we present an adolescent boy with intellectual disability and comorbid attention deficit hyperactivity disorder, conduct disorder, who was unresponsive to methylphenidate and atomoxetine but significantly benefited from clonidine treatment in ADHD symptoms and associated behavioral problems.
