<unk>  is a rare disease that is characterized by cessation of breathing in an infant for at least 20 seconds or a shorter respiratory pause that is associated with a slow heart rate, bluish discolouration of the skin, extreme paleness, gagging, choking and/or decreased muscle tone.<unk>  occurs in children under the age of one and it is more common in premature infants. Symptoms of<unk>  occur most frequently during the rapid eye movement (REM) stage of sleep. The nature and severity of breathing problems in patients can be detected in a sleep study called a polysomnography which measures the brain waves, heartbeat, body movements and breathing of a patient overnight.<unk>  can be caused by developmental problems that result in an immature brainstem or it can be caused other medical conditions. As children grow and develop,<unk>  usually does not persist.<unk>  may be related to some cases of sudden infant death syndrome (SIDS) however, the relationship between<unk>  and SIDS is not known.
