Correction

Apparently I have left the impression in the Alzheimer's Hypothesis that I no longer believe gluten causes Narcolepsy.  That is not the case.   I am sure gluten is a cause of Narcolepsy, it just doesn't also cause Parkinsons and Lewy Body Dementia and MS and Fibromyalgia- although it may contribute.
That's what I was trying to say.
Gluten antibodies in the intestines definitely contribute to orexin dysfunction.  Probably IgG4 antibodies if you want to be specific.

I have added a correction to the Alzheimer's post.
