Deep brain stimulation treats movement disorders, including dystonia (muscle contractions and abnormal postures), essential tremors, and Parkinson’s disease. DBS is a surgery used when a patient’s medication regimen and various rehabilitation strategies has become less effective in managing symptoms.
Deep brain stimulation administers a well-controlled electrical current into targeted areas of the brain. The current functions as an “off switch” by disrupting damaged brain signals responsible for the abnormal physical movement. This disruption helps restore normal activity in the brain, enabling more controlled movement. DBS does not involve destruction of brain tissue, and its effects are reversible and adjustable.
