Sleep apnea is a sleep disorder that occurs when your child’s breathing becomes partially or completely blocked repeatedly during sleep. Sleep apnea is caused by blockage of the upper airway during sleep. Common symptoms of sleep apnea are loud snoring as well as frequent awakenings from sleep. Prolonged symptoms may be associated with behavior changes and cognitive deficits. Blockage of the upper airway that causes sleep apnea in children is most often the result of enlarged tonsils and adenoids. However, other areas of your child’s anatomy may also cause the obstruction. A careful evaluation is required in order to arrive at the appropriate medical or surgical intervention.
