Head trauma increases stroke risk

Head trauma puts a blood vessel in the brain at risk of bursting, forming a blood clot, or making the blood too thin, increasing the risk of stroke.

According to US researchers, traumatic brain injury can cause brain damage. After a head injury, the person experiencing the injury experiences bleeding in the brain, which irritates the brain tissue. Because blood vessels are torn, the amount of blood to the brain decreases, leading to phenomena such as swelling, pressure on brain tissue, bruises ..

A head injury, especially a penetrating head injury, can damage or weaken blood vessels in the brain. This damage puts a blood vessel in the brain at risk of rupture leading to a hemorrhagic stroke. Moderate to severe head trauma causes blood clotting problems. If the blood cannot clot, it can also cause a stroke. For example, if too many blood clots are formed, an ischemic stroke can occur. On the other hand, if the blood becomes too thin, a brain hemorrhage can form, another form of stroke.

There are two common types of stroke caused by head trauma: hemorrhagic stroke and ischemic stroke.

Increased hemorrhagic stroke: Hemorrhagic strokes are episodes of bleeding in the brain, which can be caused by a defect in a blood vessel or by high blood pressure. A hemorrhagic stroke causes brain irritation in the area of ​​bleeding, as well as changes in blood pressure and blood vessel diameter. Hemorrhagic strokes progress quickly and are quite devastating.

Increased ischemic strokeAn ischemic stroke is a stroke caused by a blockage of a blood vessel in the brain, reducing the blood supply to an area of ​​the brain. Studies show an increased lifetime risk of ischemic stroke in the years following head injury.

In addition to studies demonstrating an increased rate of stroke after traumatic brain injury, some studies also show that recovery from stroke in people who have experienced head injuries is more difficult than in people without trauma. head. Because head trauma causes brain damage and reduces the “reserves” of the brain. This is one of the reasons why it is so difficult to recover from a stroke that occurs after a head injury.

Preventing traumatic brain injury is the way to protect yourself against future strokes. To prevent traumatic brain injury, experts recommend that people wear seat belts when driving, and wear helmets and headgear suitable for sports and adventure activities. Another valuable safety measure to prevent head injury is to avoid alcohol and drugs. Because these substances change perception and judgment when working as well as driving…

It is a fact that head trauma can increase the risk of stroke, but it is not entirely true. In some cases, with a head injury, the chance of actually having a stroke remains relatively low. According to experts, to prevent stroke after brain injury, people can do the following 5 solutions.

Know the warning signs of a stroke: The first and best way to prevent severe damage from a stroke is to recognize the warning signs. The earlier it is treated, the higher the chance of a cure.

Reduce sodium intake and monitor blood pressure: High blood pressure is the leading cause of stroke. Meanwhile, head trauma causes high blood pressure, which increases the risk of stroke. Therefore, people with head injuries should reduce their sodium intake and eat more potassium to lower blood pressure. Potassium helps reduce the effect of salt in the body and reduce stress in the blood vessels, some foods are naturally high in potassium such as bananas, avocados, sweet potatoes, tomatoes, low-fat milk …

Exercise regularly: Exercising enough to sweat a few times a week may reduce the risk of stroke. Exercise also helps lower blood pressure, which indirectly reduces the risk of stroke. The American Heart Association recommends that people do at least 40 minutes of moderate physical activity three to four times per week.

Reduce stress: The process of recovering from a head injury can be stressful, while chronic stress is a factor that increases the risk of stroke 4 times normal. This is why it’s so important to find ways to manage stress after a brain injury.

Take vitamins: Certain nutrients may help prevent stroke. Vitamins are found in many foods. Good vitamins to prevent stroke after head injury include vitamins B3, B12, omega 3 fatty acids (fish oil)…. Before starting any new vitamin, you should consult your doctor. doctor to make sure that nothing interacts with the medications you are taking.
