Brainstem hemorrhage is a very dangerous disease with poor prognosis and high mortality rate. Although the brainstem is very small, it contains almost all vital neurological functions. Once hemorrhage occurs, it can cause severe neurological dysfunction, and even lead to the patient's death due to cessation of heartbeat and breathing in a short period. So, can brainstem hemorrhage be cured? It mainly depends on the location of the hemorrhage, the amount of bleeding, and the clinical symptoms. Patients with less bleeding, hemorrhages closer to the upper end of the brainstem, and milder clinical symptoms have a better chance of recovery. However, those with more extensive bleeding, hemorrhages closer to the lower end of the brainstem, and more severe clinical symptoms have a lesser likelihood of recovery.

Why would there be bleeding in the brainstem?

Firstly, hemorrhaging can occur anywhere there are blood vessels. The brainstem is an important functional area of the human brain, connecting the cerebrum above and the spinal cord below, with the cerebellum closely positioned behind it. It serves as a crucial relay station for neural connections. This area is the control center of human life, managing vital functions such as breathing and heartbeat. Additionally, this area is densely packed with blood vessels. For patients with chronic hypertension, unstable blood pressure control can lead to degeneration and necrosis of the vessels, and even the formation of dissecting aneurysms or microaneurysms, which can cause the vessels to rupture and bleed under certain conditions. Like the vessels in other parts of the intracranial space, the blood vessels in the brainstem can also bleed. This is referred to as brainstem hemorrhage.

How long is the period of brainstem hemorrhagic edema?

Brainstem hemorrhage, like hemorrhages in other parts of the brain, also has a period of cerebral edema. Cerebral edema is primarily caused by direct injury to brain tissue following hemorrhage, local ischemic and hypoxic changes, local metabolic products, and some damage to the vascular endothelium. Generally, the edema becomes apparent three days after the hemorrhage, peaks between three to seven days, begins to subside after ten days, and completely resolves around fourteen to fifteen days. However, there are exceptions, such as cases where edema occurs shortly after injury or within a few hours, and the peak period of edema lasts for several weeks, or even up to a month without complete resolution.

Is brainstem hemorrhage painful?

Brainstem hemorrhage is relatively painful, and most patients with brainstem hemorrhage will exhibit severe headaches and dizziness. The nature of the pain is intense, resembling a cutting pain that is hard to tolerate. However, when the amount of bleeding is large, it can quickly cause damage to important nerve nuclei in the brainstem, and even affect the central nervous system responsible for consciousness, leading to the patient falling into a stupor or coma. In such cases, the patient may not feel pain, but for those who are conscious, severe headaches and dizziness, accompanied by a strong sense of vertigo, especially noticeable when changing positions, often occur.

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.
