Solving the SIDS Mystery

Finally, researchers may have discovered a potential cause of sudden infant death syndrome (SIDS), and, fortunately, their work backs up what we already know about SIDS prevention. A study from the Children's Hospital Boston found that babies who die from SIDS have irregularities in their brain's serotonin system, which keeps them from regulating body temperature, waking up, and moving if they're having trouble breathing while sleeping. Scientists hope to develop a screening test and treatment, but this may take decades. Until then, pregnant women should continue to avoid smoking and drinking, since both increase the risk of fetal abnormalities and SIDS, and they should stick with SIDS prevention guidelines.
