Changing definitions of sleep apnea – should we still treat mild sleep apnea? Whether we should treat mild sleep obstructive apnea, may depend on the definition used for scoring hypopneas.

Are you tired, sleepy, fatigued? You may have Idiopathic Hypersomnia. Sleep medicine doctors often ignore idiopathic hypersomnia. Many sleep medicine doctors focus exclusively on sleep apnea. Others understand and look for narcolepsy with cataplexy (now called narcolepsy type 1). Narcolepsy with cataplexy is a rare disorder. In my experience, narcolepsy without cataplexy (now called narcolepsy…
Sleep Deprivation Increases Brain Cannabinoids Most Americans do not get enough sleep (defined as more than 7 hours for adults, 8-10 hours for teenagers, more for children).

Which is the Best Mattress? Patients (and even referring physicians) often ask me which is the best mattress? Which mattress should they buy?

Cannot tolerate APAP? You are not alone! Are you one of those who cannot tolerate APAP (Auto-titrating Positive Airway Pressure) for sleep apnea? You are not alone! Sleep apnea is diagnosed based on finding apneas (90% decrease in airflow) and hypopneas (30% decrease in airflow plus 4% drop in blood oxygen). APAP works by supposedly…
Not getting enough sleep may set you up for brain damage We know sleep is necessary to clear toxins from the brain. Researchers just showed that even after one night of sleep deprivation, brain cells (astrocytes) that eat up connections between nerve cells become more active. This, in itself, may be an adaptive and necessary response…
Is it Necessary to Test for or Treat Sleep Apnea without other Symptoms?

Does the Fitbit really measure sleep? The Fitbit (and similar devices) has an accelerometer. It measures change in motion. That’s all. It does not measure brain waves, or breathing, or blood oxygen. It can tell whether there is a change in your movement. So if you are lying quietly and then start moving, it senses…
