Abstract:
Despite substantial advancement in psychopharmacological and electro-magnetic treatments over the last decades on the depression patients, there are non-responders remain with a chronic disease and high suicidal risk yet. Deep brain stimulation (DBS) is now being experimentally to treat the intractable depression and yielded an impressive therapeutic benefit, and especially few adverse effect occurred. The beneficial action of DBS is closely related to the stimulation sit. And the efficacy of high frequency stimulation of lateral habenula is one of the best choice. In depression, the concentration of 5-HT released by the raphe nuclei is decreased. It's due to mainly the overactivation of the lateral habenula. High frequency stimulation of lateral habenula impairs the activation of lateral habenula, and the inhibitory effect of lateral habenula on raphe nuclei is decreased. Then, the 5-HT concentration released by the raphe nuclei is increased, the pathological changes of depression is eliminated. The lateral habenula could be a promising novel target for BDS in the cases of intractable depression.
