Doctors typically diagnose Parkinson’s disease based on your symptoms, your complete medical history, and a physical and neurological exam. Based on the results, you may be referred to a center that specializes in movement disorders care or to a movement disorder specialist. Your provider may also suggest tests such as a dopamine transporter scan (DaTscan), MRI, genetic testing, or other blood tests.
DaTscan
DaTscan is an FDA-approved imaging test for evaluating Parkinson’s. This test detects levels of dopamine transporters (DaT) in certain areas of your brain. DaTscan results are useful for your doctor when your diagnosis is unclear.
