Researchers have discovered a defect in the brain stems of children who have suffered cot death. The defect causes the inhibition of the neurotransmitter serotonin, as well as influencing mood, is an important chemical in the regulation of breathing. A child with this defect is therefore not able to increase his or her rate of breathing when necessary, for example when lying on the stomach.
It is as yet unknown if the defect is due to a genetic flaw or if it arises during pregnancy.
In some cases, possible genetic causes of cot death have been found. Children who are born with two copies of the gene Y1103 have a 24 times increased risk of cot death. This causes these children to be unable to tolerate longer pauses between breaths.
A low level of vitamin A can be a factor in cot death. Research indicates that infants who get approximately 50,000 I.U. of vitamin A during the first 2 days after birth have a significantly reduced risk of dying during the first 6 months.
An elaborate article is being prepared.
