SIDS
Sudden infant death syndrome (SIDS) is a syndrome marked by the symptoms of sudden and unexplained death of an apparently healthy infant aged one month to one year. The term cot death is often used in the United Kingdom, Australia and New Zealand, while crib death is used in North America
SIDS is a diagnosis of exclusion. It should only be applied to an infant whose death is sudden and unexpected, and remains unexplained after the performance of an adequate postmortem investigation including
- an autopsy;
- investigation of the scene and circumstances of the death; and
- exploration of the medical history of the infant and family.
Typically the infant is found dead after having been put to sleep, and exhibits no signs of having suffered.
Conditions that may be undiagnosed and thus result in a diagnosis of SIDS
- Medium chain acyl CoA dehydrogenase deficiency (MCAD deficiency)
- Infant botulism
- Long QT syndrome
- Shaken baby syndrome
According to a study published in October 2006 in the Journal of the American Medical Association, babies who die of SIDS have abnormalities in the part of the brain that helps control functions like breathing, blood pressure and arousal. Researchers examined the brains of 31 babies who had died of SIDS and 10 who had died from other causes. They found that abnormalities in the brain stem appear to affect the ability to use and recycle serotonin, which is responsible for regulating mood as well as vital body functions. According to the National Institutes of Health, which funded the study, the new finding is the strongest evidence to date suggesting that innate differences in a specific part of the brain may place some at increased risk of dying from SIDS
