See your doctor if you notice shaking, stiff muscles, lack of balance or slowing down of your movement. If they suspect you may have Parkinson's disease, they will refer you to a specialist such as a neurologist or geriatrician.
It is not easy to diagnose Parkinson’s. There are no laboratory tests (such as a blood test or brain scan). Often a diagnosis is made by a specialist, such as a neurologist based on clinical signs and symptoms. The specialist will examine for any physical signs of Parkinson’s and take a detailed history of symptoms.
