Parkinson's disease mostly occurs in the middle-aged and the elderly, and its clinical symptoms may include extrapyramidal symptoms such as myotonia and tremor. How is Parkinson diagnosed. Now let's give a brief introduction, so that patients and friends can have a better understanding.

How is Parkinson diagnosed

One: brain CT, MRI examination: generally no characteristic findings, elderly patients may have varying degrees of brain atrophy, ventricular enlargement, some patients with cerebral lacunar infarction, individual basal ganglia calcification.

Second: functional imaging: pet or SPECT with specific radionuclide detection. For example, 6 - (18 fluoro) - L-dopa (6-fd) can be used to study the metabolism of dopamine, and information about the density and affinity of dopamine receptor can be obtained. It is found that the metabolism of dopamine in the brain of patients with Parkinson's disease is significantly reduced, and the absorption index of striatum can be found before clinical symptoms appear.

Third: there are prominent eye gaze disorders, muscle rigidity in the trunk is heavy, limb muscle involvement is light and better to maintain the flexibility of the limbs, neck hyperextension caused by increased neck extensor tension is obviously different from the neck flexion of Parkinson's disease, which can be differentiated from Parkinson's disease.
