Very good summary of vagus nerve devices

Thank you for the clear explanation!

Very informative. Thank you!

Can you go into more detail about the reasons, why having problems with your Vagus Nerve, would cause dizziness? I have TRD and along with that, I deal with constant dizziness (I live off of like 8 motion sickness pills a day.) I'm very treatment resistant when it comes to AD meds but, when they did work, the dizziness was the first thing to go away. (As the meds stopped working, everything came back including the dizziness). All I can think is that maybe my mental issues, are causing me to be more dizzy in some way. Still not really sure how. I'm looking into getting into a clinical trial for VNS so, I hope that clears away the major depression and dizziness!

is the mechanism of action not known? how does the VNS correct the vagus nerve?

[@real.psyched]

Indeed, there are still a lot of unknowns about the mechanisms. What is known is that for certain conditions a hypoactivity of the vagus nerve has been observed. Thus, stimulating it can be helpful

@@real.psychedso in most vagus nerve related disorders the theory is that the vagus nerve is 'out of shape' or something like that? does trauma cause the vagus nerve to weaken? i just haven't really figured out if the problem is the vagus nerve is misfiring or if it's overactive or weak lol. specifically in dysautonomia.

[@real.psyched]

I mean, there are certainly more sophisticated ideas, depending on stimulation parameters. But I am no expert on that unfortunately.
