The examination of Parkinson’s syndrome is divided into the following steps: 1. To clarify whether the patient has Parkinson’s syndrome, a detailed neurological physical examination should be performed to clarify whether the patient has resting tremor, bradykinesia, myotonia, postural gait abnormalities, and autonomic dysfunction. 2. To clarify the patient’s medical history, Parkinson’s syndrome can be divided into secondary Parkinson’s syndrome, genetic degenerative Parkinson’s The syndrome can be divided into secondary Parkinson’s syndrome, genetic degenerative Parkinson’s syndrome and Parkinson’s superimposed syndrome. In secondary Parkinson’s syndrome, medical history is a very important means of differentiation, such as Parkinson’s syndrome after encephalitis, there is a clear history of encephalitis before the disease, and only after encephalitis began to appear Parkinson’s syndrome performance. In Parkinson’s syndrome caused by drugs and toxins, there must be a clear history of drug and toxin intake.3. Imaging tests, patients should improve cranial magnetic resonance examination to observe whether there are structural abnormalities in the brain, and further improve functional magnetic resonance to observe whether there are abnormalities in the patient’s brain function.4. Genetic tests, if genetic degenerative Parkinson’s syndrome is considered, relevant chromosomal If Parkinson’s syndrome is considered to be hereditary, chromosomal and genetic screening is required to help make a clear diagnosis.
