In children it may affect in school leads to hyperactivity.
There are three forms of sleep Apnea, Central Sleep Apnea (CSA), Obstructive Sleep Apnea (OSA) and a combination of the two. Risk factors for OSA consist of being overweight, allergies and enlarged tonsils. In OSA, breathing is disturbed by a blockage of airflow, while in CSA breathing stops due to a lack of effort to breathe. Sleep Apnea is often seen with an overnight sleep.
