Parkinson’s is generally referred to neurology because Parkinson’s is an intracranial neurodegenerative disease that mainly manifests movement disorders. Once there is movement disorder and limb discomfort, it is necessary to go to the neurology department. Generally, neurologists will do a series of examinations for patients, and the first step is to combine medical history and clinical physical examination to make a diagnosis. The physical examination mainly focuses on muscle tone examination, which will reveal muscle tonicity and increased muscle tone. Next, blood biochemistry tests will be done, including routine blood work, liver function, kidney function, etc. Imaging tests include CT and MRI. However, the above-mentioned ancillary tests are not particularly valuable for the diagnosis of Parkinson’s. The focus is more on clinical manifestations. Ancillary examinations are mainly to exclude other diseases, including vascular Parkinson’s syndrome and secondary diseases. After the diagnosis is clear, the doctor will give a reasonable treatment plan. The treatment should be based on the patient’s condition, and medication should be postponed as much as possible without affecting the quality of life. Pharmacological interventions can also be given early if the patient has a high demand for life. Late stage is usually symptomatic treatment to minimize complications and maintain life.
