Patients with Parkinson's disease should not drink alcohol. This is primarily due to concerns that due to the symptoms of movement slowness and muscle rigidity, they may exhibit abnormal postural balance, greatly increasing the risk of falling. Consuming alcohol can inhibit the function of the cerebellum, exacerbating limb ataxia and increasing the risk of falling, which poses significant risks to the patient. Therefore, to protect the balance function of patients and prevent the risk of falling, they should not consume alcohol. Additionally, patients with Parkinson's disease often need to take multiple medications for their condition, and these medications should not be taken with alcohol to avoid exacerbating any adverse reactions.
