Brain stem infarcts ideally return to their normal state, the state they were in before they became ill, but this is rare. The brainstem is located below the brain, between the spinal cord and the mesencephalon, and its main function is to maintain an individual’s life with a number of important physiological functions, including heartbeat, respiration, and digestion. If a brainstem infarction occurs, it may inhibit the respiratory center, suppress the heartbeat, etc., and thus present a life-threatening situation, but whether it occurs or not depends on the exact location of the infarction. If the site of brainstem infarction is not in the various life centers and the infarcted area is small, then the recovery will be better and can be restored through systematic treatment, but if the infarcted area is large or the life centers are injured, then the general prognosis is very poor. Patients with brainstem infarction should seek medical treatment in time to avoid delaying the condition and causing serious consequences.
