Exploring Innovative Therapies

NeuroSigma, Inc. is developing trigeminal nerve stimulation (TNS) for a variety of disorders, including epilepsy, depression, attention deficit hyperactivity disorder (ADHD), post-traumatic stress disorder (PTSD) Lennox-Gastaut syndrome (LGS) and traumatic brain injury (TBI). NeuroSigma’s unique TNS technology can be delivered via the non-invasive Monarch external trigeminal nerve stimulation (eTNS™) system or the minimally-invasive subcutaneous trigeminal nerve stimulation (sTNS™) system which is currently under development.

大意是用微电流刺激三叉神经，对ADHD PTSD等等症状有辅助治疗......

现在已经在米国，加拿大，欧盟，批准使用。不过应该是处方级别的。
