First off, I would ignore Atto786's comment. The book referenced is full of unsubstantiated information about dubious interventions.
You mention sleep and seizure problems. The best place for you to get answers to those questions would be at the sleep forum:
http://www.medhelp.org/forums/show/108
Or the MedlinePlus site on sleep disorders:
http://www.nlm.nih.gov/medlineplus/sleepdisorders.html
Sleep apnea:
http://www.nlm.nih.gov/medlineplus/sleepapnea.html
Seizures:
http://www.nlm.nih.gov/medlineplus/seizures.html
These sites provide professionally screened information about assessment, diagnoses, and interventions.
Best of luck.
