London: For many patients with difficult-to-treat neuropathic pain, deep brain stimulation (DBS) can lead to long-term improvement in pain scores and other outcomes, a new study has suggested.About two-thirds of eligible patients who undergo DBS achieve significant and lasting benefits in terms of pain, quality of life, and overall health, according to Sandra G.J. Boccard, PhD, and colleagues of University of Oxford, led by Tipu Aziz FMedSci and Alex Green, MD.Some outcomes show continued improvement after the first year, according to the new study, which is one of the largest studies of DBS for neuropathic pain performed to date.The researchers reviewed their 12-year experience with DBS for neuropathic pain. Neuropathic pain is a common and difficult-to-treat type of pain caused by nerve damage, seen in patients with trauma, diabetes, and other conditions. Phantom limb pain after amputation is an example of neuropathic pain.
