For patients with cerebral hemorrhage, the specific symptoms that appear depend on the location and amount of the bleed. For example, if the bleeding is in an important area for motor function, such as bilateral bleeding in the basal ganglia region, it often leads to contralateral hemiplegia in the patient, and is likely to be accompanied by abnormal sensations in the affected limbs. Additionally, if the bleeding is located in the language function area, the patient may exhibit impaired language functions, such as speech disorders, slurred speech, and difficulty speaking. Furthermore, conditions such as anomia, motor aphasia, or mixed aphasia may also occur.

Complications of Cerebral Hemorrhage

The main complications of cerebral hemorrhage are infections or fever, especially aspiration pneumonia, which is quite common. The second complication is hyperglycemia. The third is stress ulcers and gastrointestinal bleeding. The fourth complication involves cardiac issues, as patients with cerebral hemorrhage are prone to neurogenic cardiac damage. Another complication is epilepsy; patients with lobar hemorrhage are likely to experience recurrent seizures. Additionally, there is also central fever.

Causes of cerebral hemorrhage

There are many causes of cerebral hemorrhage. In most cases, given that patients themselves already have certain underlying diseases, such as hypertension, diabetes, coronary heart disease, and arteriosclerosis, the blood pressure remains high over a long period. This causes the blood vessels to be in a constant state of tension. Over time, the vessels' ability to regulate and contract gradually weakens. When certain triggers occur, such as the patient experiencing fatigue, mental stress, or emotional excitement, the blood pressure temporarily spikes, exceeding the vessels' regulatory capacity, leading to the rupture of the blood vessels and causing cerebral hemorrhage.

What are the symptoms of cerebral hemorrhage?

For patients with cerebral hemorrhage, the symptoms vary clinically due to different amounts of bleeding and instability of the hemorrhage, which affect the surrounding brain tissue to different extents. For patients with minor cerebral hemorrhage, the impact is generally minor, and most patients only exhibit mild symptoms such as headache, dizziness, nausea, and retching. For patients with larger bleeding volumes located in crucial motor and speech functional areas, they often show symptoms such as unilateral limb paralysis and abnormal sensations in the affected limbs, accompanied by significant headaches, dizziness, reduced intellectual levels, cognitive impairments, and even aphasia.

How to Prevent Cerebral Hemorrhage

To understand how to prevent cerebral hemorrhage, we need to clarify what causes it. Generally, the most common cause of cerebral hemorrhage is hypertension. Long-term hypertension can lead to hyaline degeneration of the walls of small arteries and occlusion necrosis. Over time, small arteries rupture, leading to cerebral hemorrhage. Other blood system diseases, such as leukemia, deficiency of clotting factors, some tumors, and cerebral vascular malformations, can also cause cerebral hemorrhage. Therefore, the most important preventive measure is to actively control blood pressure. Regularly, one must maintain a low-salt, low-fat diet, engage in appropriate physical activities, enhance physical fitness, avoid smoking, and abstain from alcohol to effectively prevent hypertension and avoid hypertension-induced cerebral hemorrhage. For cerebral hemorrhage caused by other reasons, regular health check-ups should be done, including complete blood counts and coagulation tests, to rule out blood diseases causing cerebral hemorrhage.

Principles of Treatment for Cerebral Hemorrhage

For patients with cerebral hemorrhage, the main principle of treatment is to control the blood pressure in a relatively stable state. Blood pressure should not be too high or too low. If it is too low, it can easily lead to insufficient cerebral perfusion pressure, thus causing local cerebral tissue ischemia and hypoxia, leading to the occurrence of cerebral infarction. If the blood pressure is too high, it can easily exceed the regulatory function of the blood vessels, often causing secondary hemorrhage. Secondly, it is important to promptly monitor the patient's vital signs, observe the patient's consciousness, pupils, and limb movement, and timely perform a follow-up head CT scan to dynamically observe the changes in the patient's condition.
