The precursors of brainstem hemorrhage often present with abnormal symptoms such as nystagmus, limited eye movements, blurred vision, dizziness and headache, as well as having numbness in the limbs. Because of the specificity of the brainstem, the precursor symptoms of brainstem hemorrhage exist for a very short time. If a small amount of brainstem hemorrhage occurs, there will be more serious symptoms, often leading to loss of consciousness, eye movement disorders, and more serious symptoms such as motor disorders and sensory disorders of the limbs. Brain stem is an important part of the brain tissue, and if brain hemorrhage occurs in the brain stem, many nerve impulses cannot be transmitted down to the spinal cord, and the blood blocks the middle cerebral aqueduct and affects important parts of the medulla oblongata, such as the respiratory circulation center, which can lead to rapid death. Doctors should be highly aware of the presence of cerebral atherosclerosis, hyperlipidemia, meningioma, and amyloid cerebrovascular disease if the patient has these conditions. Once a patient has symptoms of brainstem hemorrhage precursors, he should go to the neurology department of a regular hospital in time to avoid delaying the condition and endangering the patient’s life.
