SIDS Research Shows Abnormalities in Babies’ Brain Chemistry

University of Adelaide researchers have confirmed that abnormalities in a common brain chemical are linked to sudden infant death syndrome (SIDS).

In the first study of its kind looking at babies outside the United States, researchers from the University of Adelaide’s Adelaide Medical School investigated 41 cases of SIDS deaths and discovered striking abnormalities in chemical serotonin within the brain.

Serotonin, otherwise known as 5-HT, is a neurotransmitter found in different parts of the human body, including the central nervous system. Among its many roles, serotonin is involved in the regulation of sleep, and also control of the cardiovascular and respiratory systems.

This latest research, published in the Journal of Neuropathology & Experimental Neurology, supports the concept that brain stem dysfunction, resulting in significantly altered serotonin expression, is associated with some SIDS deaths.
