Can Biotin Deficiency explain excessive daytime sleepiness? I have seborrheic dermatitis, lot of white hair. I underwent complete body profile including thyroid and also Polysomnogram but none of the tests were conclusive. Also have no psychological disorders.

Excessive daytime sleepiness could be caused by a variety of medical, psychiatric illnesses as well as due to primary sleep disorders. They must be evaluated in the same sequence. Consult a physician first to rule out medical causes. Once they are ruled out consult a psychiatrist.
