Zusammenfassung

Hohe Prävalenz und Komorbiditätsraten mit oftmals gravierenden psychosozialen Folgen machen die Aufmerksamkeits-Defizit/Hyperaktivitätsstörung (ADHS) bei Kindern, Jugendlichen und Erwachsenen zu einer Herausforderung für Forschung und Krankenversorgung. Zahlreiche Studien sprechen für die Annahme einer dopaminergen fronto-striatalen Informationsverabeitungsstörung ADHS-Betroffener (Störung exekutiver Funktionen). Die Übersichtsarbeit stellt die neurobiochemischen Grundlagen der seit fast einem halben Jahrhundert klinisch erfolgreich angewandten Methylphenidat-Therapie bei der ADHS im Zusammenhang aktueller Forschungsergebnisse dar (MRI, f-MRI, PET, SPECT, Genmapping). Die erhöhte striatale Dopamin-Transporter-Dichte bei ADHS-Methylphenidat-Respondern wird als ein wissenschaftlich konsequentes und brauchbares Arbeitsmodell für die klinische Praxis dargestellt.

Abstract

High prevalence and high co-morbidity rates with frequently aggravating psychosocial problems make the attention-deficit/hyperactivity disorder (ADHD) of children, adolescents and adults an important target for research and healthcare. Recent findings suggest a dopaminergic fronto-striatal information processing deficit in ADHD-patients (executive functions). This review summarizes and presents, in the context of recent studies (MRI, f-MRI, PET, SPECT, Mapping Genes) the neurobiochemical bases of the methylphenidate-therapy, clinically successfully applied since almost one half century by the ADHD. The increased striatal dopamine transporter density by the ADHD-methylphenidate-responder is reported as a scientifically sound and useful clinical working model.
