It is recommended that patients with Parkinson's disease avoid drinking alcohol. This is because the condition in Parkinson's patients is caused by the death of certain neurons in the substantia nigra of the midbrain. It is well-known that alcohol has a direct damaging effect on neurons. Therefore, drinking alcohol could potentially worsen the symptoms of Parkinson's disease, and it is advised not to drink alcohol. Additionally, patients with Parkinson's disease are prone to panic and unstable gait. If alcohol consumption affects the function of the cerebellum, it will exacerbate the patient's instability in walking, making them very prone to falls and potentially causing complications such as fractures. Furthermore, drinking alcohol can lead to orthostatic hypotension, which is a lower blood pressure when standing up. Parkinson's disease itself can also cause this type of orthostatic hypotension, and the combination of the two can cause a significant drop in blood pressure in patients, posing a risk when standing.
