Parkinson's disease is a relatively common degenerative disease in the elderly, primarily causing the death of dopamine neurons in the substantia nigra of the midbrain, leading to corresponding clinical manifestations. Research has confirmed that other systems may also be damaged in the early stages of Parkinson's disease symptoms. The early symptoms may primarily include: First, patients experience persistent constipation, which is a very important early symptom of Parkinson's disease. Second, some patients may experience sleep disturbances, mainly characterized by tossing and turning, shouting out loud during sleep, without being aware of it. Additionally, some patients in the early stages may also experience a reduced sense of smell, constipation, cognitive impairment, and other clinical manifestations. There are also some early motor symptoms, mainly that the patient becomes clumsy and inflexible in the movements of one side of the body. These are the early symptoms of Parkinson's disease.
