Multiple sclerosis, strokes and head injuries are the most common causses of these kinds of tremors. Another problem associated with movement disorders, especially Parkinson's disease, is a slowing of movement and rigidity of the body. There is no cure for multiple sclerosis or Parkinson's disease, but surgical techniques may help control tremors and rigidity. Neurosurgeons at UT Southwestern Medical Center at Dallas say the surgery involves creating a small lesion in the brain that interrupts the electrical pathways that cause the symptoms. The procedure is done under local anesthetic, with only a two-inch incision in the scalp.
Computers guide the instruments to the part of the brain that is affected.
Doctors say patients need to be awake during the procedure so the surgeon can test the position before creating the lesion. As with any surgery, there are risks involved. But there also are many people who could have the chance at improved quality of life if they are candidates for the surgery.
