Chronic neuropathic pain is estimated to affect 3%-4.5% of the worldwide population. It is associated with significant loss of productive time, withdrawal from the workforce, development of mood disorders such as depression and anxiety, and disruption of family and social life. Current medical therapeutics often fail to adequately treat chronic neuropathic pain. ⋯ In this review, the authors briefly discuss the history of DBS for chronic neuropathic pain in the United States and present evidence supporting dACC DBS for this indication. They review existent literature on dACC DBS and summarize important findings from imaging and neurophysiological studies supporting a central role for the dACC in the processing of chronic neuropathic pain. The available neurophysiological and empirical clinical evidence suggests that dACC DBS is a viable therapeutic option for the treatment of chronic neuropathic pain and warrants further investigation.

Questions from patients about pain conditions and analgesic pharmacotherapy and responses from authors are presented to help educate patients and make them more effective self-advocates. This article provides information to patients regarding the treatment of neuropathic pain syndrome. It narrates how a doctor might explain neuropathic pain to a patient and particularly discusses the use of anticonvulsants.

Review[Exploration of novel therapeutic targets for neuropathic pain based on the regulation of immune cells].
The pathogenesis of neuropathic pain is quite complicated and diverse. Because pre-existing analgesics, such as opioid analgesics and nonsteroidal anti-inflammatory drugs, are not sufficient to treat it, it is a serious task to establish a strategy of remedy for neuropathic pain. Recently, increasing evidence suggests that immune cell-mediated neuroinflammation in the nervous system induces central and peripheral sensitization, resulting in chronic pain. ⋯ Activated immune cells produce and release several kinds of inflammatory mediators, which act directly on sensory neurons and promote a recruitment of immune cells, developing the feedback loop of inflammatory exacerbation. We've focused on the role of crosstalk between immune cells and neurons in peripheral neuroinflammation, and explored a novel candidate for a remedy of neuropathic pain. In this review, we will introduce recent reports and our research work that suggest the functional significance of neuroinflammation in neuropathic pain, and survey possibilities of new strategies for chronic pain from the point of view of basic research.
