Brain Chemical Imbalance Gives Clue To Trigger Of SIDS

Researchers from the European Molecular Biology Laboratory in Monterotondo, Italy have found a new clue about the trigger of SIDS, or sudden infant death syndrome.

SIDS is the third leading cause of death among infants between the ages of a week and a year-old, with 2,500 infants in the U.S. dying every year from the disease.

They found in a study on mice that a chemical imbalance in the brain of serotonin could cause SIDS.

If serotonin signaling is blocked completely, it did not trigger SIDS, but when the balance is off via over-expressing the serotonin 1A autoreceptor, it can lead to SIDS

This research has revealed new clues as to how serotonin signaling can actually be life-threatening, and gives clues about SIDS.
