If you or a loved one has Parkinson's disease (PD), you may know that the diagnosis is based on a person's medical history and physical examination. This is because we don't have a biomarker -- an objective measurement (such as a blood test or a brain image) -- to make the diagnosis.
In this short video, I discuss how doctors diagnose Parkinson's, and what The Michael J. Fox Foundation and others are doing to find a biomarker. I also talk about a brain imaging test you may have heard of called a dopamine transporter (or DaT) scan and how it's currently used in the evaluation of PD.
Through the "Ask the MD" blogs and video, I translate the latest research and communicate treatment options for people with PD and their loved ones. I hope you find these resources to be a helpful guide on your journey with Parkinson's.
Stay tuned for regular updates, and join our upcoming webinar where we'll talk more about developments toward earlier, more precise diagnosis of Parkinson's.
Thanks for being part of our community.
