Yes, bethsheba, narcolepsy is one of the conditions related with
hypersomnia. But so also are sleep apnea and dysfunctions of
the autonomic nervous system. Also that CFS contributes to it.
This according to the National Institute of Neurologic Disorders.
I am having a sleep study done to determine if that is my main
cause. But I am investigating the autonomic possibility as I have
symptoms of dysautonomia that worry me. I was diagnosed many
years ago with CFS, so tis very confusing. Thanks for looking into
the subject. Sure doesn't seem like anyone else in this "Sleep
Disorder" board shares this conditon...if the number of replies can
be relied upon as a measure.
