What are the symptoms of cerebral hemorrhage? Different parts have different reactions

Studies have found that there are many sites of cerebral hemorrhage, and the symptoms manifested in different places are also different. For example, in the case of cerebellar hemorrhage, if the amount of bleeding is small, the clinical manifestations are often dizziness first, followed by severe headache, frequent vomiting, unsteady walking, and slurred speech; if the amount of bleeding is large and compresses the medulla oblongata life center, severe cases may result in sudden death.

1. Internal capsule hemorrhage: It is the most common bleeding site. Its typical clinical manifestations are the contralateral "three hemiplegia" (hemiplegia, hemisensory disturbance, and hemianopsia). The range of internal capsule hemorrhage is larger and the symptoms of nerve damage are more severe. However, if the bleeding is on the outside of the internal capsule and mainly damages the external capsule, the clinical symptoms are usually milder, there is usually no disturbance of consciousness, the hemiplegia is also mild, and the prognosis is better.

2. Thalamic hemorrhage: If the thalamic hemorrhage is unilateral and the amount of bleeding is small, the symptoms include contralateral mild paresis and contralateral hemisensory disturbance, especially obvious proprioception disturbance. If the amount of bleeding is large and the damaged area affects the contralateral thalamus and hypothalamus, vomiting of coffee-like substances will occur, the vomiting is frequent and projectile, and there are symptoms such as polyuria, glycosuria, paralysis of the limbs, and eyes looking towards the tip of the nose. The condition is often serious and the prognosis is poor.

3. Lobar hemorrhage: also known as subcortical white matter hemorrhage, can occur in any lobe of the brain. In addition to headache and vomiting, bleeding in different cerebral lobes also has different clinical manifestations. For example, frontal lobe hemorrhage may cause mental symptoms such as irritability, suspicion, contralateral hemiplegia, motor aphasia, etc.; parietal lobe hemorrhage may cause contralateral sensory disturbances; temporal lobe hemorrhage may cause sensory aphasia, mental symptoms, etc.; occipital lobe hemorrhage is most common with hemianopsia. The symptoms of lobar hemorrhage are generally slightly milder and the prognosis is relatively good.

4. Pontine hemorrhage: The pons is a common site for brainstem hemorrhage. The early symptoms are paralysis of the affected side and spread of the opposite limbs, which is called crossed paralysis. This is the clinical feature of pontine hemorrhage. If the amount of bleeding is large, it will affect the opposite side, causing symptoms such as quadriplegia, pupil constriction, high fever, and coma; if the blood breaks into the fourth ventricle, serious symptoms such as convulsions and irregular breathing will occur, and the prognosis is usually poor.

5. Cerebellar hemorrhage: If the amount of bleeding is small, the clinical manifestations are often dizziness first, followed by severe headache, frequent vomiting, unsteady walking, and slurred speech; if the amount of bleeding is large, it will compress the medullary life center, and in severe cases, sudden death may occur.
