Usually, the outward symptoms of Parkinson's are distinctive enough for a doctor to make a diagnosis in the office. There is no blood test or brain scan that confirms the diagnosis. But if you don't respond to the drugs used to treat Parkinson's disease, it’s possible you may have another type of movement disorder that causes the same type of symptoms. Doing additional tests can help your doctor determine if some other problem is causing your parkinsonian symptoms.
Levodopa is thought to be the most effective drug for controlling symptoms. But many doctors prescribe dopamine agonists in the beginning of the disease. This is because after a few years, levodopa can cause motor complications (times when the medicine suddenly stops working or when you have uncontrollable jerking movements). Talk to your doctor about which medicines are best for you.
Increasing, decreasing, or stopping the medicines you are taking may cause big changes in your symptoms and can be dangerous. Even if a medicine doesn't seem to be working, when you stop taking it, your symptoms of Parkinson's disease may be worse.
Taking medicine with food
Early in the disease, it might be helpful to take pills with food to help with nausea, which may be caused by some of the medicines for Parkinson's disease.
Later in the disease, taking the medicines at least 1 hour before meals (and at least 2 hours after meals) may help them work best.
Some medicines for Parkinson's disease don't work as well if you take them at the same time you eat food with protein in it, such as meat or cheese. The protein can block the medicine and keep it from working as well as it should.
