Periaqueductal/periventricular gray deep brain stimulation for the treatment of neuropathic facial pain.

Background: The Periaqueductal gray (PAG) and the periventricular gray (PVG) are the anatomical targets for deep brain stimulation (DBS) to treat severe, refractory neuropathic pain.

Methods: Seven (four female and three male) patients were qualified for PAG/PVG DBS because of neuropathic facial pain. Frame-based unilateral implantations of DBS were conducted according to indirect planning of the PAG/PVG, contralateral to reported pain (3389, Activa SC 37603, Medtronic).

Quality of life and depressive symptoms in Parkinson's disease after subthalamic deep brain stimulation: a 2-year follow-up study.

Aim: To assess the correlation between quality of life (QoL), depressive symptoms and motor signs in patients with Parkinson disease after subthalamic deep brain stimulation (DBS STN).

Material And Methods: 74 patients, average age 55.6 ± 7 and duration of disease 12.
