Ricciardi L, Fischer P, Mostofi A, et al. - In the present study, the researchers sought to examine local field potential (LFP) markers of trait impulsivity in Parkinson disease (PD) and their relationship to impulsive compulsive behaviors (ICB). LFPs from the subthalamic nucleus were recorded in 23 PD patients undergoing deep brain stimulation implantation. The presence and severity of ICB were evaluated by clinical interview and the Questionnaire for Impulsive‐Compulsive Disorders in PD‐Rating Scale, while trait impulsivity was estimated with the Barratt Impulsivity Scale. The findings point to a link between α power and trait impulsivity in PD, regardless of the presence or severity of ICB.
