In the outpatient clinic, I met several patients who complained of walking weakness and were diagnosed with cervical spondylosis and lumbar disc herniation in several hospitals and given the corresponding treatment, to no avail. They were diagnosed with cervical spondylosis and lumbar disc herniation and given corresponding treatment, but to no avail. Later, after careful physical examination, they were considered to have Parkinson’s disease, and their symptoms were significantly relieved after treatment with Mydopa and Tysudar. The reasons for the misdiagnosis I analyzed were mainly the following: 1. The patient’s symptoms were not typical in the early stage of the disease; 2. The wrong department was consulted; 3. The doctor was less responsible and did not check the body carefully; 4. The doctor did not have enough knowledge about the disease. As a patient, you should also be able to recognize Parkinson’s disease. If there is weakness of both lower limbs, self-conscious stiffness of arms and legs, difficulty in taking steps, difficulty in turning around, and slow movements, Parkinson’s disease should be excluded. If hand tremors occur, Parkinson’s disease should be highly suspected and promptly seen by a regular hospital neurologist.
