Expanding on this tradition is the use of functional imaging and intraoperative mapping to safely remove lesions in or near brain essential for functions such as language and motor skills. Functional Neurosurgery For many patients with Parkinson's disease or essential tremor, medications alone are often inadequate to control disabling symptoms. Some of these patients may benefit from stereotactic neurosurgical procedures to improve their level of function. The most common neurosurgical procedures performed for movement disorders by neurosurgeons at Washington University School of Medicine and Barnes-Jewish Hospital in St. Louis are pallidotomy, thalamotomy, thalamic deep brain stimulation, and subthalamic deep brain stimulation. Pain Trigeminal neuralgia, also called tic douloureux, is one of the most excruciating pains known to mankind.
Trigeminal neuralgia is more common in women than in men.
It occurs mainly in middle age and older patients. The pain is described by the patient as a sudden excruciating shock-like paroxysm of pain lasting a short time, usually less than a minute, although it may recur at irregular frequent intervals, sometimes with multiple repetitions of pain within a few minutes. It may arise and spread into any part of the face. It can be triggered by eating, talking, brushing the teeth, rubbing the part of the face where the pain arises, or by cold wind. Recurrent attacks of pain usually remain localized to the area of the face in which it originated.
