A)A brainstem abnormality, when combined with a stressor such as sleeping in the prone position in a child in the first 6 months of life, will often result in SIDS due to a decreased arousal and head turning response during times of asphyxia. A brainstem abnormality does not decrease the respiratory drive during NREM sleep, increase periods of apnea, or increase the risk of aspiration and airway obstruction.
