Diagnosis of Parkinson disease
Correct diagnosis is most important
Symptoms progress slowly, and so may go unnoticed or be attributed to a different disease, or similar symptoms may occur as side effects of medication taken to treat a different condition. If symptoms are present, you should see a specialist neurologist to obtain a correct diagnosis.
The symptoms seen in Parkinson's disease may also be present in other disorders, and may stem from a range of different causes, including an untreatable degenerative neuronal disorder known as parkinsonian syndrome, Parkinson disease-like symptoms in patients with a previous history of cerebral infarction (this condition is clearly differentiated from Parkinson disease, and should be considered as parkinsonian syndrome), after-effects of hydrocephalus or encephalitis, and side-effects of medication. Although a judgment can be made regarding the severity and extent of symptoms and their stage of progression, diagnostic imaging such as computed tomography (CT), magnetic resonance imaging (MRI), or nuclear medicine scanning may be carried out to distinguish Parkinson's disease from these other conditions.
