Increased behavioral inhibition trait and negative stress coping in non-rapid eye movement parasomnias

摘要

Study Objectives: Reduced gray matter volume in the posterior cingulate cortex (PCC) has recently been found in patients with non-rapid eye movement (NREM) parasomnia, providing a neuroanatomical substrate for the arousal state dissociation. It remains unclear whether PCC changes in NREM parasomnias might also play a role in cognitive or affective dysfunction in these patients. The aim of this exploratory study was to investigate neurobehavioral correlates of PCC abnormalities in patients with NREM parasomnia.
