Synopsis

An apparent life-threatening event (ALTE) is a common reason for parents to seek medical care for their infants. It is not a specific physiologic diagnosis but a description of a clinical scenario. An ALTE occurs when an infant experiences some combination of apnea or breathing changes, color change, and change in muscle tone. Part of the definition of an ALTE is that these changes must be frightening or concerning to the infant's caregiver. Most ALTEs occur in infants 10 weeks of age or younger. ALTEs may be caused by normal infant breathing behaviors, minor conditions such as viral infection, or more serious conditions such as seizure. A specific cause is frequently not identified.
