question: My 16 year old granddaughter has episodes of hallucinations, complete disorientation to time, place, date; followed by extreme sleepiness where she can sleep solidly for 8-12 hours.  She has been to several neurologists who tell her its all in her head & have done nothing to alleviate her symptoms-just seek mental health counseling.  She has Hashimotos disease & severe migraines (since age 3).  She is about to graduate from High School & attend college, but cannot drive for fear of one of these episodes will cause a wreck.  Any suggestions?  I can be reached at  YYYY@YYYY .  Thank you. Sarah Wagoner-worried grandma
