Another experimental technique, stereotaxic thalamotomy, involves cutting parts of the thalamus, the brain's center for relaying messages from the muscles and sensory organs. Studies show it can reduce some hemiparetic tremors. Back to Top Treating Complications Incontinence, caused by faulty control over the bladder muscles, can be treated with exercises, biofeedback, prescription drugs, surgery or surgically implanted devices that replace or aid muscles. Drooling, caused by poor functioning of the muscles of the throat, mouth and tongue, can be more difficult to control. Anticholinergic drugs reduce the flow of saliva, but may produce side effects like mouth dryness and poor digestion.
Surgery sometimes helps, but also can worsen swallowing problems.
Biofeedback has been proven helpful in patients who are intellectually unimpaired and motivated. Eating and swallowing problems may require the caregiver to prepare food in a semisolid fashion, such as strained vegetables and fruits. Physical therapy can support and promote proper positioning while eating or drinking, or help extend the neck away from the body to reduce the risk of choking. Severe swallowing problems may necessitate the use of a tube to deliver food down the throat and into the stomach. A more invasive practice called gastrostomy is sometimes necessary.
