Exploring how low doses of ketamine can help treat Parkinson's disease

Official title: Mechanisms of Low-Dose Ketamine Treatment for Parkinson's Disease

Funded at University of Arizona · NIH-10874780 · Data updated 2026-11-12

This study is looking at how low doses of ketamine might help people with Parkinson's disease by reducing unwanted movements that can happen with regular treatments, and it will involve some infusions and check-ups to see how it affects their symptoms and brain activity.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals diagnosed with Parkinson's disease who are experiencing movement difficulties and may be affected by L-DOPA-induced dyskinesia.

Less likely to help

Patients who do not have Parkinson's disease or those who are not experiencing significant movement issues may not benefit from this research.

What this research studies

This research investigates the effects of low-dose ketamine on patients with Parkinson's disease, a condition that causes movement difficulties due to dopamine loss in the brain. The study aims to understand how ketamine can potentially reduce the severity of involuntary movements caused by traditional treatments like L-DOPA, which often lead to debilitating side effects. By examining the brain's electrical activity and plastic changes, the research seeks to identify a new therapeutic approach that could improve patient outcomes. Participants may receive low-dose ketamine infusions and undergo assessments to monitor changes in their symptoms and brain activity.

Why it matters

Potential benefit: If successful, this research could provide a new treatment option that alleviates symptoms of Parkinson's disease without the severe side effects associated with current therapies.

How similar studies have gone: Previous studies have shown that low-dose ketamine can be effective in treating conditions like treatment-resistant depression and PTSD, suggesting potential for success in Parkinson's disease treatment as well.
