Answer

No laboratory or imaging study is required in patients with a typical presentation. Such patients are aged 55 years or older and have a slowly progressive and asymmetric parkinsonism with resting tremor and bradykinesia or rigidity. Patients who do not have tremor should generally be considered for MRI evaluation to exclude brain lesions such as stroke, tumor, or demyelination.
