What causes dizziness after a cerebral hemorrhage?

Generally, dizziness after cerebral hemorrhage may be caused by factors such as impaired cerebellar function, postural blood pressure fluctuations, cerebral edema, cerebral ischemia, and cerebral vasospasm. It is recommended to seek timely medical attention, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. A detailed analysis is as follows:

1. Impaired cerebellar function: Cerebral hemorrhage may involve the cerebellum or its connecting fibers. The cerebellum is responsible for balance and coordination, and damage to its function may cause dizziness accompanied by unsteady gait and poor coordination. Balance training, such as standing exercises and gait training, should be conducted under the guidance of a rehabilitation specialist. Medications such as Cytidine Diphosphate-choline Sodium Tablets, Oxiracetam Capsules, and Butylphthalide Soft Capsules may be used as prescribed to improve cerebral metabolism and promote recovery of cerebellar function.

2. Postural blood pressure fluctuations: Prolonged bed rest after cerebral hemorrh combined with sudden changes in posture may lead to poor blood pressure regulation, temporarily reducing cerebral perfusion and causing dizziness. Symptoms are more noticeable when standing and ease when lying down. Transition slowly between positions: sit up for a moment before standing. Monitor blood pressure changes and, if necessary, use medications such as Midodrine Tablets, Shengmai Oral Liquid, and Yiqi Yangxue Oral Liquid as directed to regulate blood pressure and improve cerebral perfusion.

3. Cerebral edema: Local cerebral edema following hemorrhage may compress surrounding nerves and blood vessels, affecting the function of the balance center and causing dizziness accompanied by headache and nausea, typically evident within several days after the hemorrhage. Patients should rest in bed with the head of the bed elevated 15°-30°, and use medications such as Mannitol Injection, Glycerol Fructose Injection, and Furosemide Injection as prescribed to reduce cerebral edema and intracranial pressure. Dizziness will ease as the edema subsides.

4. Cerebral ischemia: After cerebral hemorrhage, the brain's vascular regulatory function declines, reducing cerebral blood flow and causing cerebral ischemia and hypoxia, which can lead to dizziness accompanied by dizziness and fatigue, worsening after physical activity. Maintain quiet rest and avoid strenuous activity. Use medications such as Ginkgo Biloba Extract Tablets, Xueshuantong Injection, and Sanqi Tongshu Capsules as directed to improve cerebral circulation, increase cerebral blood flow, and alleviate dizziness.

5. Cerebral vasospasm: Blood from the hemorrhage may irritate cerebral vessels, inducing vasospasm and further reducing cerebral blood flow, worsening dizziness and accompanied by headache and confusion. This typically occurs 3-14 days after the hemorrhage. Patients must remain absolutely bedridden and avoid emotional excitement. Use medications such as Nimodipine Tablets, Fasudil Hydrochloride Injection, and Vincamine Injection as directed to relieve vasospasm and improve cerebral blood flow. In severe cases, endovascular interventions such as balloon angioplasty may be performed to relieve vasospasm and restore cerebral blood supply.

In daily life, maintain a comfortable position while resting in bed, change positions slowly, and avoid sudden head turns or standing up. Follow a light, low-salt diet, avoid overeating, maintain regular bowel movements, and prevent straining during defecation, which can加重 cerebral strain. Family members should assist patients with passive limb exercises to prevent deep vein thrombosis and monitor the patient's emotional state to avoid anxiety exacerbating dizziness.
