Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The aim is to study a specific group of PD patients, carriers of mutations in the glucocerebrosidase (GBA) gene, which is the most common genetic risk factor for PD and is a harbinger of aggressive cognitive and motor decline. Approximately 12-17% of PD patients undergoing DBS are GBA mutation carriers. GBA mutation carriers with PD have a specific phenotype characterized by more significant motor dysfunction and reduced short-term visual memory function compared with their non-GBA counterparts. Thus as GBA mutation carriers have a "signature" phenotype, the investigators hypothesize that these GBA mutation carriers have a unique "signature" of oscillatory activity that can be distinguished from non-mutation carriers during motor activation and during cognitive tasks. Identification of this "signature" will provide critical information that is required to: 1) understand the underlying neurophysiological mechanisms responsible for the aggressive disease course of GBA associated PD, and 2) further develop customized adaptive DBS systems.
