Strike that, Reverse it

So I finally got around to reading the Summary of the FDA Patient Conference on Narcolepsy.

Most of it is just reporting the annoying State of the Paradigm, but this part really bugs me...

Some participants commented on the need to better understand and target the underlying cause(s) of the disease, for example orexin or hypocretin loss.
A few commented that sodium oxybate targets the underlying cause (sleep consolidation) but that other options are needed for patients who cannot take sodium oxybate.

Who is telling people that narcolepsy is caused by a breakdown in sleep architecture?
Hmmmm.   I wonder.
That sounds kinda backwards to me.
