I have narcolepsy and it's hard to describe what an absolute fog I was in for years before diagnosis. The current best treatment is a powerful depressant taken at bed time and again middle of the night to induce deep sleep.
Is that gabapentin? Or is there something else that is the go to these days?
There was a comment on reddit a few days ago from someone with narcolepsy who was looking for a sleep tracker.
Sadly, our technology does not "induce" deep sleep.
It is suspected that the reason the Alzheimer's study showed such an increase in deep sleep was due to decreased cortisol as a result of stimulation, but that is just a theory at this point.
Sodium oxybate. And yeah most commercial sleep trackers are not going to work for someone with such disordered sleep. There have been retail EEGs available but they never catch on.
