All the different sequelae of cerebral hemorrhage can potentially occur after a brainstem hemorrhage. This is because the brainstem is a critical link between the brain and the body, acting as the command center within the headquarters. Of course, whether sequelae will occur and which ones will occur after a brainstem hemorrhage primarily depends on the amount of bleeding and the location of the bleed.

If the bleeding in the brainstem is minor and occurs in a less critical area, the sequelae are usually minimal, and some people might not experience any sequelae at all.

However, if there is substantial bleeding in the brainstem and the area affected is crucial, the patient may remain comatose for a long period. Even if they are revived and regain consciousness, they may suffer from severe functional impairments and experience numerous sequelae.

Pre-symptoms of brainstem hemorrhage

Brainstem hemorrhage is extremely dangerous, and once a massive hemorrhage occurs, the patient can quickly lose consciousness and generally there are no effective emergency measures available. The patient will quickly die due to the involvement of the centers controlling heartbeat and breathing. The early symptoms of brainstem hemorrhage are not particularly obvious, but a careful medical history may reveal that patients often experience excessive fatigue, stress, emotional agitation, and poor sleep before the hemorrhage. Patients may show early signs such as dizziness, blurred vision, double vision, limb weakness, and slurred speech. If a patient has very high blood pressure and exhibits these early symptoms, especially if there is discomfort in the neck and upper back area, it is crucial to be highly vigilant and seek immediate medical attention. The prognosis for brainstem hemorrhage is very poor, thus it is essential to focus on preventive measures and properly control blood pressure.

How to rehabilitate through exercise after brainstem hemorrhage

Regarding the specific measures for rehabilitation exercises for brainstem hemorrhage, it is necessary to analyze specific problems based on the different conditions of the patients. Based on our past experience, several common symptoms of brainstem hemorrhage can be addressed with corresponding rehabilitation measures. The first one is swallowing disorder, which is very common in patients with brainstem hemorrhage. We can provide patients with electrical stimulation and ice stimulation, and teach them morning exercises such as cheek puffing, tongue stretching, and dry swallowing practices. The second common issue is articulation disorder, for which we can teach patients some speech training. Usually, we can prepare patients with rhythm, cadence, and deep breathing exercises for speech training. The third is the dysfunction of limb mobility. For specific activities, we need to conduct training, including some balance function training.

Causes of brainstem hemorrhage

The causes of brainstem hemorrhage mainly include the following aspects: The first aspect is hypertension; arteriosclerosis is the most important cause of brainstem hemorrhage because prolonged high blood pressure and continuous impact of blood flow easily lead to damage and disease of the blood vessels, forming small aneurysms. These aneurysms eventually rupture, causing brainstem bleeding. The second aspect is vascular malformations in the brainstem area, which are another major cause of bleeding. Most patients under 40 with normal blood pressure and no coagulation disorders can find vascular malformations in the brainstem area after undergoing DSA examinations following brainstem hemorrhage. The third aspect is heavy drinking leading to increased blood pressure, impaired liver function, abnormal coagulation, etc., ultimately causing bleeding in the brainstem area.

How long does it take for the fever to subside after a brainstem hemorrhage?

For patients with brainstem hemorrhage, it is common to develop high fever after the bleeding, where the body temperature often exceeds 38.5℃. There are many reasons for the occurrence of high fever. It can be considered that the presence of an intracerebral hematoma compresses the hypothalamic temperature set point, causing abnormalities in the set point function and leading to central fever, with temperatures often reaching 39℃ or even higher than 40℃. At this time, the use of antipyretic drugs alone generally has poor therapeutic effect. It often requires the effective absorption of the intracerebral hematoma for the body temperature to gradually return to normal. Another situation, considering the occurrence of pulmonary infection, it is necessary to promptly provide patients with antibiotics for effective treatment. When the pulmonary infection is effectively controlled, the body temperature will also gradually decrease.

Can brainstem hemorrhage be cured?

For brainstem hemorrhages that have already occurred, the patient should be immediately taken to a local hospital. Initially, a cranial CT scan should be performed to determine the location and amount of bleeding in the brainstem. For minor brainstem hemorrhages, it is recommended to first use medication for treatment. This involves administering drugs that stop bleeding, enhance brain function, promote dehydration, and nourish the nerves, aiding in the gradual cessation of bleeding and the absorption of cerebral hematomas. Most patients can achieve very good treatment outcomes. However, if the brainstem hemorrhage is extensive, it often leads to severe brainstem dysfunction and typically has a poor prognosis.
