Only in recent years, ADHD has been recognized as a genetically complex psychiatric disorder in adults. Currently, one can assume that between 3 and 5% of all adults are affected by it. The genetic underpinnings of this disorder are subject of current investigation. There are a number of open questions regarding diagnosis and therapy. In the area of diagnostics there are conceptual questions such as about central aspects of assessment. With regard to the conceptualization of the disorder there still remains a reference to the operationalization of the disorder in children and young people with the central aspects of inattention, hyperactivity and impulsivity. Whether this is sufficient, has increasingly been criticized. Thus, for example, emotional dysregulation also seems to play an important role, which has been demonstrated in various studies. Furthermore, the development and evaluation of psychometric tests and norms are important as well as the assessment of the consequences of the disorder (e.g. traffic). However, in terms of therapy, the successful use of methylphenidate has demonstrated, but not all patients respond in a sufficient way. Therefore it is important to examine other supplementary treatment options, such as e.g. the efficacy of psychotherapy or omega-3 fatty acids.
