No particular test exists to analyze Parkinson's disease. Your doctor trained in nervous system conditions (nervous system specialist) will diagnose Parkinson's disease dependent on your medical history, an audit of your signs and symptoms, and a neurological and actual examination. Your doctor might recommend a particular single photon emission computerized tomography check called a dopamine carrier filter. Though, this can assist with supporting the doubt that you have Parkinson's disease, it is your manifestations and neurologic examination that at last decide the right diagnosis. Most individuals don't need a DaTscan.
