Scientists have published new studies that may provide groundbreaking insights into Sudden Infant Death Syndrome (SIDS). This is an event that previously confused the medical community.

According to the Mayo Clinic, SIDS is an unexplained death of a seemingly healthy baby under the age of one, usually during sleep. According to the CDC report, SIDS accounted for 37% of sudden infant deaths in the United States in 2019.

Researchers at the Westmead Children’s Hospital in Sydney, Australia, have now been able to determine the cause of sudden infant death syndrome.

The medical community previously believed that SIDS was caused by complications of the infant part of the brain that regulates respiratory regulation during sleep.

The latest study found that infants who died of SIDS had lower levels of an enzyme known as butyrylcholinesterase (BChE).

This enzyme is thought to help scientists regulate the pathways in the brain that promote human breathing, confirming that scientists first hypothesized.

“Abnormal-The previously unidentified cholinergic deficiency identified by BChEsa is present at birth in SIDS infants and concludes that it represents a specific premortal measurable vulnerability. “The researchers said.

Dr. Carmel Harrington, an emeritus researcher who led the study, said the findings were groundbreaking. Harrington said the study provided an explanation for SIDS and hopes for the prevention of deaths associated with this mysterious condition.

“It’s a nightmare for all parents that an apparently healthy baby doesn’t fall asleep, and until now there was no way to know which baby would die, but it’s no longer the case. Earlier I found the first marker to indicate a vulnerability, “Harrington said in a news release.

Researchers explained that BChE plays an important role in the wakefulness pathway of the brain. They further explained that BChE deficiency may indicate a defect in the baby’s arousal, which reduces their ability to wake up and respond to the external environment and makes them more susceptible to SIDS. bottom.

“Baby has a very powerful mechanism to tell you when you’re not happy. Usually, when you’re faced with a life-threatening situation, such as having difficulty breathing while sleeping because your baby is on your stomach, your baby Cries with excitement. This study shows that some babies do not show this same strong arousal response, “Harrington said.

Dr. Matthew Harris, a pediatrician for emergency medicine at Cohen Children’s Medical Center / Northwell Health in Long Island, NY, was not involved in the study, but told Fox News: To a limited extent, studies appear to show that low levels of this enzyme increase the risk of sudden infant death syndrome. Importantly, this provides an opportunity for early screening of perinatal risk factors, an opportunity for scientists and physicians to discover interventions. ”

According to pediatricians, how parents avoid SIDS:

  • Lay your baby on his back for all sleep time
  • Do not leave loose blankets that can choke your child
  • Keep your baby in the sleeping area of ​​your parents or guardians for at least 6 months, but not in the adult bed
