Attention-deficit/hyperactivity disorder (ADHD) is a common child psychiatric disorder, which occurs in approximately 4-6% of school-aged children. The symptoms of ADHD cause difficulties in academic performance, during leisure activities and affect family-, and peer relations as well. The most effective treatment for managing ADHD is the combination of non-pharmacological and pharmacological interventions. The aim of this paper is to introduce the "Fészek" program - which takes place in Vadaskert Child and Adolescent Psychiatry Hospital and Outpatient Clinic - where children with the diagnosis of ADHD or showing the symptoms of ADHD go through the diagnostic procedure and participate in a cognitive behavioral therapy program.
