Study of Conscious Behavior Under Low-frequency Deep Brain Stimulation in Chronic and Severe Post-coma Disorders of Consciousness (Post-coma DBS)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
Chronic post-coma consciousness impairment is a severe handicap. Preliminary studies suggest that deep brain stimulation of the thalamic-tegmental reticular system could improve consciousness disorders, and facilitate the emergence of conscious behavior. The aim of this protocol is to study the effects of deep brain stimulation on conscious behavior, using a patient-based anatomic mapping for stereotactic surgery, and the Coma Recovery Scale-Revised (CRS-R) as clinical assessment criterion.
Condition or disease
Chronic and Severe Post-coma Disorders of Consciousness (Permanent Vegetative State, Minimally Conscious State)
Other: Implantable neurostimulation system
Total length of inclusion for a patient: 10 months (2 months before electrodes implantation, 8 months after).
