What Causes Cerebellar Hemorrhage? What Are the Symptoms?

Update Date: 2024-05-22 Source: Network

Cerebellar hemorrhage is a relatively common type of cerebral hemorrhage, and its harm is extremely significant. If the patient's recovery is not effective, it can easily lead to sequelae, causing serious conditions such as motor dysfunction, intellectual disabilities, and aphasia. There are many reasons for cerebellar hemorrhage. For elderly people, it may be related to some underlying diseases. The symptoms are also quite diverse. Understanding the symptoms before the onset can help prevent it in time.

1. Hypertension

This is a relatively common cause. If the blood pressure rises in patients with cerebral arteriosclerosis, microaneurysms may rupture and bleed. The long-term existence of hypertension stimulates the intima of the cerebral medullary arterial vessel wall, leading to fibrous necrosis or hyaline degeneration. When blood flow increases or blood pressure rises significantly, it is prone to rupture and bleeding.

2. Cerebrovascular Amyloidosis

Some abnormal substances deposit in the small and medium-sized arteries of the leptomeninges, the outer membrane, or the cerebral cortex. The older the age, the higher the risk of onset. Due to the occurrence of lesions, it can lead to cerebellar hemorrhage. Bleeding may occur in the deep tissue of the cerebral hemisphere, and CT examination is needed to actively deal with it in the correct way.

3. Anticoagulants and fibrinolytic agents

Incorrect use of these drugs is also one of the reasons for cerebellar hemorrhage, such as aspirin, heparin, etc. Improper treatment may lead to such consequences. Other possible causes include various cerebral arteritis, arteriosclerosis, hemorrhagic cerebral infarction, thrombocytopenic purpura, aplastic anemia, leukemia, hemophilia, etc.

4. Symptoms of Cerebellar Hemorrhage

Cerebellar hemorrhage manifests as vertigo, headache, vomiting, ataxia, pupil constriction, and positive meningeal irritation signs. During hemorrhage, the white blood cell count increases, and cerebrospinal fluid examination is often bloody. CT examination within one week of onset can confirm a hematoma with a diameter greater than or equal to 1 cm.
