Vagus nerve stimulation (VNS) reveals a optimistic remedy impact and improved high quality of life (QoL) amongst sufferers with treatment-resistant melancholy (TRD), based on two research printed on-line Dec. 18 in Mind Stimulation.
Charles R. Conway, M.D., from Washington College in St. Louis, and colleagues performed a multicenter, double-blind trial involving 493 adults with treatment-resistant main melancholy who had been randomly assigned to obtain 12 months of lively or no stimulation sham VNS; 88.4 p.c of individuals accomplished the trial. The researchers discovered that the p.c time in Montgomery-Åsberg Melancholy Ranking Scale response couldn’t differentiate lively from sham VNS. Nonetheless, antidepressant advantages considerably favored lively VNS primarily based on rankings from on-site clinicians and offsite masked raters.

Based mostly on the Mini-Q-LES-Q, WPAI merchandise 6, and Q-LES-Q, lively VNS was superior to sham in time spent in clinically significant profit.
“What’s really important here is that patients themselves were reporting that their lives were improving,” Conway stated in a press release.
