What this trial studies

This clinical trial aims to evaluate the effectiveness of low doses of levetiracetam, an anti-epileptic drug, in addressing memory issues associated with Parkinson's disease. The study will utilize neuroimaging techniques to assess the impact of the drug on specific brain regions, particularly the hippocampal subfields. Additionally, it will compare brain activity between Parkinson's patients with and without memory problems, as well as healthy older adults, to identify predictive markers for memory impairment in Parkinson's disease. This proof-of-concept trial could pave the way for future targeted therapies.

Who should consider this trial

Good fit: Ideal candidates include Parkinson's disease patients with mild cognitive impairment, those without memory impairment, and healthy volunteers eligible for MRI scans.

Not a fit: Patients with dementia or significant non-Parkinson's neurological diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new treatment options for memory impairment in patients with Parkinson's disease.

How similar studies have performed: While this approach is novel, similar studies targeting cognitive impairment in neurodegenerative diseases have shown promise.
