Under Polysomnogram: There are several short videos under this word for those preparing for a sleep study.
Under Narcolepsy: Many of the videos about narcolepsy focus on cataplexy. There are several about narcoleptic dogs. I especially liked the one titled Doggy Narcolepsy.
Under Sleep Apnea: There are many videos about sleep apnea, but the one that captured my curiosity is called Sleep Apnea Exercises. There is a website at www.sleepapneaexercise.com that goes with it. It's advocating an exercise program to help those with apnea who can't tolerate a CPAP. Would someone in that situation check it out and report on what they are suggesting, please?
