Are you aware of any studies for those with Parkinson's disease-related dementia who have undergone Deep Brain Stimulation (DBS) surgery? Though not recommended at the time (due to cognitive decline/mild dementia), my wife underwent DBS to address her debilitating physical symptoms. Ten years later, I/We certainly don't regret the surgeries (1 per side) as she immediately saw improvements in her movements/flexibility/dyskinesia all while reducing her medications. However, hallucinations/anxiety/confusion have spiked up in the past couple years. As such, I'd be interested in hearing from those in a similar situation (Parkinson's disease-related dementia who have undergone Deep Brain Stimulation). Thanks!
