My mom was diagnosed with parkinson's disease 2 yrs ago. am i likely to have it too? what are the odds? should i be tested?

No Definitive Test: Although pd can run in families, we still do not have a definitive test. You can see the neurologist that your mother sees and get an opinion. Some new scanning techniques (dat scans) can be helpful in certain circumstances. But, no one can administer a test that will give you a concrete answer. Pd is made on what we call a clinical diagnosis, but you need to see a movement disorder specialist.
