High Levels Of Serotonin in Blood of SIDS Infants Contains

High levels of serotonin were found in blood samples from infants who died of Sudden Infant Death Syndrome (SIDS) .

High levels of serotonin were found in blood samples from infants who died of Sudden Infant Death Syndrome (SIDS).It is a chemical that carries signals along and between nerves, according to a study funded in part by the National Institutes of Health.

The finding raises the possibility that a test could be developed to distinguish SIDS cases from other causes of sleep-related, unexpected infant death. The study, led by Robin L. Haynes, Ph.D., of Boston Children's Hospital and Harvard Medical School, appears in the Proceedings of the National Academy of Sciences. NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) provided funding for the work.

Sudden Infant Death Syndrome - Overview
Sudden Infant Death Syndrome is death of a baby, under one year of age that occurs in sleep and cannot be explained.

‘SIDS is the sudden death of an infant under one year of age that remains unexplained after a complete autopsy and death scene investigation.’

In the current study, researchers reported that 31 percent of SIDS infants (19 of 61) had elevated blood levels of serotonin. In previous studies, the researchers reported multiple serotonin-related brain abnormalities in SIDS cases, including a decrease in serotonin in regions involved in breathing, heart rate patterns, blood pressure, temperature regulation, and arousal during sleep.

Taken together, the researchers wrote, the findings suggest that an abnormality in serotonin metabolism could indicate an underlying vulnerability that increases SIDS risk and that testing blood samples for serotonin could distinguish certain SIDS cases from other infant deaths. However, they caution that more research is needed.

NICHD's Safe to Sleep campaign provides information on ways to reduce the risk of SIDS and other sleep-related causes of infant death.

Despite Risk of SIDS, More Parents Share Beds With Infants
The number of parents or caregivers who sleep with their infants has grown significantly over the recent years.

SIDS Deaths Rise by 33 Percent on New Year's Day - Study
New Year may not be a good start for all, as a new study has found that the number of babies who die of SIDS, or sudden infant death syndrome, increases by 33 percent on New Year's Day.
