Background: ADHD (Attention Deficit Hyperactivity Disorder) is a common neuropsychiatric disorder in todays’ society. In earlier research it has been assumed that ADHD is a diagnosis existing only in childhood, but more recent studies show that the majority of individuals with ADHD have remaining symptoms in adulthood. The diagnosis means clinical and psychosocial disabilities which have a negative effect on the individuals in their daily lives. Because of this it is crucial to find non-pharmacological options since research has proven that non-pharmacological and pharmacological treatments combined decrease the ADHD symptoms more effectively. Aim: The aim of this study is to describe the non-pharmacological care and treatment and its impact on adults with ADHD.

Method: The method is a literature review based on quantitative articles that have been analyzed to create an overview of the existing research on non-pharmacological treatments for adults with ADHD. Results: The result generated in three themes, structure, awareness and healthy diet. The treatments under the themes structure and healthy diet showed significant impact in the reduction of ADHD symptoms in adults. Treatments that showed most impact were mainly CBT (Cognitive Behavioral Therapy) based interventions. Conclusion: Based on the findings, the conclusion was that there are non-pharmacological options for adults, but there is also a continuing need for research in non-pharmacological treatment for adults with ADHD to promote the person's well-being.
