Pallidotomy and thalamotomy can reduce specific symptoms for some patients. The result is a permanent lesion in the brain. DBS devices are similar to cardiac pacemakers and do not make permanent lesions. Research is continuing in an effort to determine the long-term value of these surgeries. Progress Through Research Research in Parkinson's disease, especially using animal models of the disease, provides tremendous hope for patients.
Research focuses on prediction, prevention, and treatment.
Some investigators are examining how the brain and motor system regulate movement. Others are searching for environmental factors or toxins that might cause or contribute to the onset of the disorder. Others are interested in why some people seem to be genetically more susceptible to getting the disease. Only through continued research can can we hope for more treatments and a cure.
