Symptoms and signs of brainstem hemorrhage
The symptoms and signs of brainstem hemorrhage must be judged based on the situation. There are many nerve fibers in the brainstem, and bleeding in any area could lead to different clinical manifestations. The most common general symptoms include headache, nausea, dizziness, vomiting, and numbness and weakness in the limbs, and even conditions such as drowsiness, stupor, and even coma may occur. If more severe, it could cause abnormal rhythms in heart and respiratory functions, and some special symptoms might appear. For example, hemorrhage in the midbrain might cause bilateral pupil constriction, especially pinpoint constriction; if the hemorrhage occurs in the medulla, it could cause respiratory and circulatory arrest early on.
