Brainstem stroke commonly results in impairment of which automatic functions?

• A. Impaired automatic functions such as breathing, heart rate, temperature, sleep/wake cycles, digestion, swallowing, balance, and dizziness
• B. Enhanced language abilities
• C. Increased appetite
• D. Normal autonomic functions

Answer: (A)

Brainstem strokes disrupt the brain’s automatic control centers that regulate essential bodily functions. The medulla and nearby brainstem structures manage breathing and heart rate, temperature regulation, sleep–wake cycles, swallowing and digestion, and balance. When these centers or their pathways are affected by a stroke, these automatic functions can become impaired, leading to breathing or heart rhythm changes, trouble with temperature regulation, disrupted sleep, swallowing difficulties, digestive issues, and dizziness or balance problems. The other ideas don’t fit the typical impact of a brainstem stroke—language is mainly controlled by cortical areas, increased appetite isn’t a hallmark effect of brainstem damage, and normal autonomic function would not occur if the autonomic centers are disrupted.
