It very interesting because vagus nerve theory has been seen as unproven and is often cast upon with doubt as we don’t understand the underlying mechanism - a lot of PTSD treatments are along those lines. I think they just don’t work universally/don’t understand the myriad pathways of presentation and are bad at predicting them - IE PTSD is a set of symptoms but we try to see it as a set of causes). There’s a big problem with “evidence based” because many fall into the cracks. An implant is quite a thing though - looking at the wiki for VNS it seems to be seen as effective for a whole array of things, but without understanding why.
