Cerebral ischemia, learn what are the risk factors to identify it

With intense headache, the perception of not feeling an arm and a strong dizziness, came on Saturday, June 1, television presenter Jota Mario Valencia to New Hospital Bocagrande, Cartagena, where he was hospitalized for several days until Thursday, June 6 he died.

The symptoms with which Jota Mário arrived are characteristic of cerebral ischemia, a health problem that occurs when the blood flow of a certain area of ​​the brain is insufficient. When there is not enough blood, the nerve cells in the area are deprived of oxygen and nutrients, so they do not function properly.

If blood flow does not recover immediately, cells in the affected area begin to die, and this causes injury and damage that can leave sequelae or disrupt the patient's life.

Thrombus or hemorrhage?

This type of stroke can occur in two ways. The first is because of a thrombus, that is, a blood clot that forms inside a blood vessel. The second is because of a rupture or hemorrhage in one of the veins through which the blood "escapes".

Ischemic stroke

Also known as cerebral ischemia. It occurs when the cessation of blood flow is caused by a clot that clogs a blood vessel in the brain. It is also known by the names of thrombosis or embolism.

There is talk of thrombosis when the clot or thrombus formed in the wall of the cerebral artery and we spoke of embolism when this clot originated in other parts of the body – like the heart – and traveled through the bloodstream to the impact. in one of the cerebral vessels.

"When a clot or thrombus is generated, the first thing to do is to try to consult the specialist as soon as possible to try to clear the blood vessel from the brain.This can be achieved by injecting an intravenous drug or by suctioning the vessel and so try to unblock so that small brain damage occurs, meaning less damage to the brain, "explains Adriana Caballero, neurologist at Imbanaco Medical Center.

Hemorrhage or stroke

It occurs when the lack of blood supply to the brain is caused by the rupture of a vessel, with the consequent internal hemorrhage that it causes.

The specialist explains that both bleeding and thrombosis are "equally serious and complicated" medical problems.

Learn to detect symptoms

When cerebral ischemia occurs, the most important thing is to act quickly because every minute counts.

You may be aware of what is happening to you, but it is common for people around you to detect that something strange is happening and it is they who should act as soon as possible by notifying the emergency department.

"Some examples of symptoms that you can identify are that from one moment to another they present any type of visual disturbance – see blurred – change when raising the arms or feel pain in the arm or leg," explains specialist Adriana Caballero.

Below you will find other signs that should make you suspect and visit your specialist as soon as possible to prevent cerebral ischemia.

Crooked mouth

It is common, during a cerebral ischemia, to see that his mouth twists a little and that he has difficulty in smiling. It may also be difficult to drink because the liquid will be spilled at one end.


If you feel dizzy and struggle to get up, it may be that ischemia is affecting the area of ​​the brain responsible for balance.

Difficulty in speaking

Having sudden difficulty in speaking or understanding others can also be indicative of problems. If you are in a conversation and have trouble articulating words or building a sentence from one moment to another, consult your doctor quickly.

Risk factors

Cerebral ischemia occurs suddenly. There are people who are more predisposed than others to suffer and it depends a lot on your state of health and lifestyle. Here are some things to keep in mind to avoid these dangerous episodes.

Monitor blood pressure: Having high blood pressure can increase your risk of ischemia or brain hemorrhage up to 5 times.

Manage Your Cholesterol: this helps maintain the health of the arteries and thus avoids ischemia. Monitor your diet by promoting foods high in fiber and vitamins and limiting animal fats.

Prevent diabetes: It is an important risk factor, since it accelerates the process of vascular aging, affecting all the vessels of the organism. Try to maintain a reasonable weight and limit the refined sugars.

Exercise: This protects the arteries of the brain and heart. With 25 minutes a day of physical activity, you can significantly reduce the risk of suffering from cerebral ischemia.
