Deep brain stimulation is a surgical intervention used to treat movement disorders, including dystonia, essential tremor and Parkinson’s disease, when the regimen of existing medications and various rehabilitation strategies become less effective in managing symptoms.
DBS administers a well-controlled electrical current into targeted areas of the brain. This electrical current functions as an “off switch” by disrupting abnormal brain signals responsible for the abnormal physical movement. This disruption helps restore normal activity in the brain, thus enabling more controlled movement. DBS does not involve destruction of brain tissue, and its effects are reversible and adjustable.
