What symptoms of Parkinson’s are improved by deep brain stimulation?

Deep brain stimulation improves symptoms of tremor, stiffness, and slowness. The best predictor of which symptoms will improve with deep brain stimulation are those that improve with medications for Parkinson disease, such as levodopa, pramipexole, or ropinirole. Some symptoms do not respond as well to DBS. These include balance, speech, and memory.

Deep brain stimulation improves Parkinson’s symptoms such as controlling tremors and rigidity and allows patients to better perform tasks themselves.
