Parkinson's disease can not be cured, but medications can help control the symptoms. In some later cases, surgery may be advised. Doctor may also recommend life style changes, especially ongoing aerobic exercise. In some cases, physical therapy that focuses on balance and stretching also is important. A speech-language pathologist may help improve your speech problems.
Medications may help you manage problems with walking, movement and tremor. These medications increase or substitute for dopamine, a specific signaling chemical (neurotransmitter) in your brain.
People with Parkinson's disease have low brain dopamine concentrations. However, dopamine can't be given directly, as it can not enter your brain.
