Read our Parkinson Disease research guide →Researchers have noticed that some people with Parkinson's disease crave and eat more sugary foods than others. This study investigates whether consuming fast-acting sugars (like glucose) affects insulin levels in the blood and improves Parkinson's symptoms like movement problems. The researchers will compare how your body and symptoms respond to glucose versus a placebo (a sugar-free comparison) to understand this connection.
Many patients with Parkinson's report increased cravings for sugary foods, sometimes even before motor symptoms appear. Scientists think this might be the brain's way of self-treating symptoms through insulin and dopamine changes, but no one fully understands why this happens or whether it actually helps. This trial aims to uncover that connection.

You will visit the research center and complete two glucose tolerance tests on separate occasions: one with real glucose and one with a placebo (fake) drink. During each visit, researchers will measure your blood sugar and insulin levels, and they will assess your Parkinson's symptoms before and after consuming the drink. The study uses a crossover design, meaning you'll do both tests so researchers can compare your body's response to real sugar versus placebo. You'll be grouped based on whether you report cravings for sweets, which helps the researchers understand if sugar affects different patients differently.
