Abstract:
Capgras syndrome is a delusional misidentification syndrome (DMS) which can be seen in neurodegenerative diseases such as Lewy body dementia and, to a lesser extent, in Parkinson's disease (PD). Here, we report the case of a 78-year-old man with a history of idiopathic PD who developed Capgras syndrome following bilateral subthalamic nucleus deep brain stimulation (DBS) implantation. As the risk of DMS has been related to deficits in executive, memory, and visuospatial function preoperatively, this case highlights the importance of continuing to improve patient selection for DBS surgery. Capgras syndrome is a rare potential complication of DBS surgery in PD patients with preexisting cognitive decline.
