Persons suffering from Attention deficit/hyperactivity disorder (ADHD) struggle with complications within the functions that regulate and control the brain activities, due to deficiencies in these functions within the affected nerve-paths. ADHD is a cognitive function impairment characterised by inattention, impulsiveness and over activity. According to Diagnostic and Statistic Manual of Mental Disorders, American Psychiatric Association (DSM-IV), certain diagnostic criteria of ADHD must be fulfilled in order for a person to be diagnosed with ADHD. The everyday problems caused by ADHD are individual and medication can have positive effects relieving the person’s impairing behaviour. The study is based on scientific literature, three quantitative scientific articles and preview material from the last study by Johnson, Fransson, Kadesjö & Gillberg, presently being scrutinised. Swedish as well as English literature has been used. The purpose of this study is to shed some light upon whether medication facilitates the child’s school situation. The result deals with the ADHD diagnosis and pharmacological therapy involving drugs that stimulate the central nervous system, as well as naturopathic medicine like Omega-3/6. The pedagogical aspect for children with ADHD in school has been observed and evaluated. In this matter it is important for the pedagogue to encourage the child by letting it find out that it can manage more than it thinks.
