Final answer:
Scientists believe that brain stem abnormalities alone may not be enough to cause SIDS. Other factors such as lack of oxygen, carbon dioxide intake, overheating, or infection may also contribute to the occurrence of SIDS.
Step-by-step explanation:
Scientists believe that brain stem abnormalities alone may not be enough to cause SIDS. They theorize that another event must also occur to cause an infant to die of SIDS, such as lack of oxygen, carbon dioxide intake, overheating, or infection. These factors can contribute to a lack of proper oxygenation, an increase in carbon dioxide levels, an imbalance in body temperature, or a compromised immune system, putting the infant at risk of SIDS.
