NCT ID NCT05998772
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looks at why many people with Parkinson's disease eat more sugary foods. Researchers will give 50 participants a sugary drink or a placebo on different days, then measure blood sugar, insulin, and movement symptoms. The goal is to see if fast-acting sugars temporarily improve motor function or other symptoms.
