BRUE

Brief Resolved Unexplained Event is a term denoting a change in the appearance and behavior of a newborn or infant that cannot be explained by other circumstances. The episode lasts less than 1 minute, ends spontaneously (self-limiting) and must meet at least one of the following criteria:
 * 1)  or irregular breathing;
 * 2) reduced reactivity to stimuli from the environment.
 * 1)  or irregular breathing;
 * 2) reduced reactivity to stimuli from the environment.

It is a nosological unit replacing the previously used term ALTE (Apparent Life-Threatening Event). ALTE also included in its criteria a rubric and a description of the event in the eyes of the parent or caregiver as "life-threatening". Today, it is estimated that more than 50% of ALTEs would be explained after careful examination.
