KEY POINTS
Parasomnias are unwanted physical events or experiences that happen while falling asleep, sleeping, or waking up.
Parasomnias involve sleep-related behaviors and experiences that you can’t control.
Parasomnias may include strange movements, behaviors, emotions, perceptions or dreams.
Parasomnias occur when aspects of sleep and wakefulness overlap.
You usually remain asleep during the event and may have no memory that it occurred.
Am I at Risk ?
Excess body weight is the leading risk factor for obstructive sleep apnea, but thin people can have sleep apnea too. The risk also increases if you have a large neck, tongue, tonsils or jaw. Sleep apnea is more common in men than in women, but the risk for women increases during and after menopause. Sleep apnea is common in people who have high blood pressure. It also occurs frequently in people who have heart disease, stroke, a mood disorder or Type 2 diabetes.
GENERAL OVERVIEW
Parasomnias may include abnormal movements, behaviors, emotions, perceptions or dreams. The behaviors may be complex and appear purposeful to others, but you are asleep while the behavior is taking place. Often you will have no memory that it occurred.
