Abstract
Attention-Deficit/Hyperactivity Disorder (ADHD), characterized by a developmentally inappropriate, pervasive and persistent pattern of severe inattention, hyperactivity, and/or impulsivity with an early onset and associated with substantial functional impairment, is one of the most common mental disorders affecting around 5.3 % of children and adolescents.
ADHD symptomatology frequently co-exists with several other types of psychopathology, including oppositional defiant and conduct disorder, emotional lability, anxiety and depression, and persists into adulthood in a substantial number of cases. The disorder has a complex and probably heterogeneous pathogenesis, including multiple genetic and environmental risk factors of mostly small effect size which are acting together to cause a range of underlying neurobiological and neuropsychological alterations. According to various national and international guidelines, multimodal treatment components include psychoeducation, psychological interventions and various pharmacological treatment options. Interventions should be based on a comprehensive assessment and diagnosis, involving the integration of information from different sources, and interventions should be closely monitored for both efficacy and adverse effects.
The presentation summarized the current state of research with a special focus on recent research findings on underlying genetic and environmental risk factors, pathophysiological mechanisms, neurobiological and neuropsychological correlates, associated evidence based and alternative treatment options and proposed DSM-V changes.
Keywords: ADHD, pathogenesis, diagnosis, treatment.
