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!

What PD meds is she on?
Meds and combos of meds especially taken long term and advancing age, can all add up to halucinations, confusion, anxiety..
May or may not be relatable to DBS.

Appreciate the quick response! Her regular meds include: Neupro patch, Carbidopa-Levodopa ER, Rasagiline, Wellbutrin, as well as Clonazepam and Melatonin before bedtime.
