SIDS, Sudden Infant Death Syndrome, Possible or Probable Cause?
In this study it was found that there was a 20% decrease in a protein called orexin in the babies who had died of SIDS compared with a control group of 12 babies. “Orexin, also called hypocretin, is a neuropeptide that regulates arousal, wakefulness, and appetite. Narcolepsy is caused by a lack of orexin in the brain due to destruction of the cells that produce it.”
Interleukin (IL)-1β, a cytokine, was also found in high concentrations in babies that had died of SIDS (http://www.neurology.org/content/61/9/1256.short).
The following is an article that sheds more light on Orexin (http://www.hormonesmatter.com/adverse-reactions-orexin-hypocretin-neurons/).
