Zusammenfassung
Der vorliegende Beitrag beschreibt neben dem Störungsbild und seinen Unterformen (Kontrollzwänge, Waschzwänge mit Infektionsängsten, Horten und Sammeln, Symmetriezwänge und Rituale) die wesentlichen neuropsychologischen Funktionsbeeinträchtigungen sowie die neuronalen Netzwerke, in denen zwangsspezifische Auffälligkeiten gefunden wurden. Es handelt sich dabei um eine Erweiterung frontostriatothalamofrontaler Schaltkreise. Trotz des frühen Starts der neurobiologischen Psychotherapieforschung bei Zwangsstörungen ist die Zahl der Studien bisher noch recht überschaubar. Sie werden beschrieben und auch Perspektiven für eine integrierte neurobiologische und psychologische Prozessforschung aufgezeigt. Zusammen mit Psychotherapie lassen sich in Zukunft das Neurofeedback mit Echtzeit-fMRT und die nichtinvasive Neuromodulation evtl. zu vielversprechenden Kombinationsansätzen ausbauen.
Abstract
Obsessive-compulsive disorders are associated with different neuropsychological impairments concerning executive functions, error monitoring, decision making and other basic functionalities. Contemporary neurocircuitry models emphasize the dysfunction of the fronto-striato-thalamo-cortical network related to parietal regions, the orbitofrontal cortex, the anterior cingulate cortex and other limbic structures. In brief, studies on the functional neuroanatomy of psychotherapy effects realized by positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) are reported. Perspectives concern combined process-outcome research with repeated neuroimaging and highly resolved (daily) self-ratings focussing the nonlinear dynamics of psychotherapeutic change processes. New therapeutic approaches could explore the combination of psychotherapy with fMRI-based real-time neurofeedback and noninvasive neuromodulation with coordinated reset stimulation focusing on the desynchronization of pathologically oversynchronized neural populations and networks.
