Central pain syndrome is a neurological condition caused by a dysfunction that specifically affects the central nervous system (CNS), which includes the brain, brainstem, and spinal cord.
The disorder occurs in people who have -- or who have experienced -- strokes, multiple sclerosis, Parkinson's disease, brain tumors, limb amputations, brain injuries, or spinal cord injuries. It may develop months or years after injury or damage to the CNS.

How Is Central Pain Syndrome Treated?
Pain medications often provide little or no relief for those affected by central pain syndrome. However, some antidepressants and anticonvulsants can be useful in treating central pain syndrome. Doctors recommend people with the condition be sedated and the nervous system kept quiet and as free from stress as possible.
