SIDS Linked to Low Levels of Serotonin – 1

Narrator: This is NIH Health Matters. A study is showing that infants who die from sudden infant death syndrome, also called SIDS, produce low levels of serotonin.

Dr. Willinger: The neurotransmitter, serotonin, is decreased in the brain stem of the babies who died from SIDS.

Narrator: Dr. Marian Willinger is the Special Assistant for SIDS research at the Eunice Kennedy Shriver National Institute of Child Health and Human Development.

Dr. Willinger: In this part of the brain the transmission of nerve impulses takes information from outside sensory information. For example, your temperature, how much carbon dioxide or oxygen that’s in your blood. And then it may tell the body to increase how you breathe or wake up.

Narrator: For information on SIDS research, visit www.nichd.nih.gov. Health Matters is produced by the National Institutes of Health, part of the U.S. Department of Health and Human Services.
