Diagnosing Parkinson’s in the early stages can be hard. At first, signs and symptoms may look like other health problems or the effects of normal aging. For this reason, a health care provider may want to observe symptoms for a period of time until they are consistently apparent.
Right now, blood or lab tests are not used to diagnose Parkinson’s. Diagnosis is based mainly on a person’s health history and nervous system exam. This may include:
- Neurological exam: This includes examining symptoms and their seriousness.
- Trial test of medicines: When symptoms are severe, a trial test of medicines (mainly levodopa or L-dopa) may be used. If symptoms ease from the use of levodopa, this suggests a Parkinson’s diagnosis.
- CT scan: This imaging uses X-rays and a computer to make images of the body, including the bones, muscles, fat and organs. CT scans are more detailed than general X-rays.
- MRI: This test uses large magnets, radio waves and a computer to make detailed images of organs and structures within the body.
