A hemorrhage in the hindbrain is a very dangerous thing. The hindbrain refers to the cerebellum or occipital lobe, which is part of the brain, and the hemorrhage can easily destroy the visual nerve center, causing loss of vision and visual field defects and other related symptoms. The cerebellar hemorrhage is also very dangerous and may cause uncoordinated movement of the limbs, ataxia and unstable walking, and if serious, it may compress the brainstem, causing loss of respiratory and circulatory functions, resulting in more serious damage and even life-threatening. Brain hemorrhage, a large amount of bleeding can easily cause respiratory and cardiac arrest, and must be clinically alert.
