Minty relief? menthol gel tested for Parkinson's symptoms

This study tests whether applying menthol to the skin can improve motor symptoms and sleep quality in people with early-stage Parkinson's disease. Researchers will enroll 80 adults aged 30-80 who have had Parkinson's for less than 3 years and report poor sleep. Participants will use a menthol-based topical treatment, and the study will measure changes in movement and sleep using standard rating scales.
