Parkinson’s disease is usually a disease of the elderly, and once the disease is present, they are often unable to take care of themselves, and many of them are unable to perform basic grasping movements due to static fibrillation. However, sometimes young people also have this condition, so how to diagnose Parkinson’s disease? Let’s find out together. Symptoms that a patient with Parkinson’s disease should have: resting tremor, bradykinesia, cogwheel-like muscle tonus, and postural reflex disorder, and the patient should have at least 2 of these symptoms. Parkinson’s disease characteristics: patients with Parkinson’s disease do not have traumatic brain injury, cerebrovascular disease, viral infection, carbon monoxide poisoning, metal poisoning and other triggers; no extraocular muscle paralysis, cerebellar signs, postural hypotension, cone system damage and myasthenia and other signs; levodopa treatment is effective. Cerebrospinal fluid examination: examination of dopamine metabolites, i.e., high vanillic acid is reduced, and the content of growth inhibition and aminobutyric acid in cerebrospinal fluid is reduced. Urinalysis: decreased homovanillic acid in the urine. Positron emission tomography: Significantly reduced striatal dopamine transporter function, reduced dopamine transmitter synthesis, and D2 dopamine receptor activity in early hypersensitivity and later hyposensitivity. Molecular biology: reduced HVA levels in cerebrospinal fluid and urine can be detected, and DNA blotting techniques may reveal gene mutations in a small number of patients with familial PD. Brain CT examination: generally no characteristic changes, brain atrophy and ventricular enlargement are seen in older patients, and some patients have cerebral cavernous sclerotic foci. Do you now understand the diagnosis of Parkinson’s? When your family is afflicted by Parkinson’s must be related to the diagnosis of treatment, and then according to the situation related to the treatment, to determine can be restored to the best state, and Parkinson’s control is no problem at all.
