To diagnose sleep apnea, sleep disorders experts at Franklin Square study a patient during an overnight stay at the hospital's Sleep Center. A variety of readings are taken during the course of the study, from heart rate to brain activity. An estimated 18 million people suffer from sleep apnea. The disorder presents itself in all age groups and both sexes but is most common among men. Others most likely to develop this condition snore loudly, are overweight or have high blood pressure, have some physical abnormality in the nose or other parts of the upper airway, or frequently smoke and drink.
Sleep apnea appears to run in families, suggesting a possible genetic basis.
