![]() ![]() ![]() Chiari malformation is uncommon, but increased use of imaging tests has led to more-frequent diagnoses. When this process is disturbed or interrupted, it can cause structural defects in the brain and skull. The brain stem is found at the base of the brain and is made up of three main parts: the midbrain, pons, and medulla oblongata. These cells grow and form the different regions of the brain. It occurs when part of the skull is misshapen or smaller than is typical, pressing on the brain and forcing it downward. Brain development that occurs during the prenatal months is largely under genetic control, although clearly the environment can play a role for example, it is well known that the lack of nutrition (e.g., folic acid) and the presence of toxins (e.g., alcohol) can both deleteriously influence the developing brain. The brain stem sits below your brain like the stem of a flower. ![]() Among the babies who died of SIDS, the researchers identified differences in how the neurotransmitter serotonin bound to their so-called 5-HT2A/C receptors, found in the lower brainstem. Chiari malformation (kee-AH-ree mal-for-MAY-shun) is a condition in which brain tissue extends into the spinal canal. To learn more, Robin Haynes at Boston Children’s Hospital, Massachusetts, and her colleagues analysed the brainstems of 70 deceased infants, of whom 58 died of SIDS and 12 died of other causes. Why it occurs is unknown, but is thought to include a combination of factors, such as a baby’s development and their environmental exposures, such as to cigarette smoking.

SIDS occurs when an apparently healthy infant dies unexpectedly, usually during the first six months of their life while they are asleep. A better understanding of the condition’s causes could help scientists to develop a test that predicts a baby’s SIDS risk. The medulla, which is sometimes called the medulla oblongata, is the long, lower section of the brain stem. The research highlights the need for early and prompt assessment and intervention. Researchers may have identified a biological mechanism behind sudden infant death syndrome (SIDS). Babies with flat head syndrome may be at heightened risk of developmental delays, a new study has found. Sudden infant death syndrome may partly be caused by reduced binding of the neurotransmitter serotonin to receptors in the lower brainstem ![]()
