It is caused by the degeneration of dopamine-producing neurons in the substantia nigra, a brain region essential for movement control. The characteristic motor symptoms of PD include tremor, rigidity, bradykinesia, and postural instability. In addition to these motor impairments, many individuals with PD also experience non-motor symptoms, such as sleep disturbances, which can significantly impact their quality of life. Unfortunately, there is currently no cure for PD.\n\nMenthol, a naturally occurring compound found in peppermint essential oil, has been shown to activate TRPM8 receptors in somatosensory neurons. Pharmacological activation of peripheral TRPM8 receptors enhances neural activity, which is subsequently transmitted to the brain.\n\nIn previous preclinical studies, the investigators used a dopamine toxin-induced PD mouse model and treated the mice with distal limb immersion in menthol. The results of immunohistochemical staining showed that limb immersion in menthol reduced the loss of dopamine neurons and increased the dopamine content in the mouse striatum. The mice's motor function also improved, as indicated by a significant increase in the time they spent running on the rotarod. The investigators also evaluated the effects of menthol in a stroke mouse model induced by MCAO. Topical application of menthol to the paw alleviated acute cerebral infarction and ischemia-induced sensorimotor deficits in MCAO mice.\n\nIn our recent clinical trial, the investigators evaluated the effects of menthol-containing gloves and socks in acute ischemic stroke patients. After four weeks of treatment, patients showed improvements in their Modified Rankin Scale (mRS) and Barthel Index (BI) scores, suggesting that this intervention may help enhance functional recovery. Based on these promising results, the investigators hypothesize that a similar approach could benefit individuals with PD.\n\nThe investigators aim to conduct a double-blind, randomized controlled trial evaluating the effectiveness of menthol-containing gloves and socks in treating motor deficits and sleep disorders in patients with PD：A total of 80 patients with PD will be randomized into the following groups: (1) menthol-containing gloves and socks (2) placebo. The treatment duration will be 4 weeks, with 4 weeks follow-up. All patients will be clinically assessed at the randomization, 4 and 8 week.
