Stroke Day: Stroke Symptoms – Health

There is talk of a stroke when a vascular event occurs in the brain. And in reality, according to the neurologist Gustavo Castro, a stroke (CVA) is nothing other than the interruption or reduction of the blood supply that reaches a part of the brain.

This prevents neurons from receiving oxygen and nutrients, so in a matter of minutes they can begin to die. LCA, Castro says, can occur when an artery or a blood vessel is plugged inside the skull or when any of them ruptures.

In the case of obstruction, this may be due to a thrombus (blood clot), so it is also called thrombosis, or a plunger (a non-blood content that travels through the vessels) and this is known as an embolism.


The ruptures, adds the neurologist, can occur due to malformations in the blood vessels such as aneurysms (such as bulging of the walls of the arteries) or due to weakening caused by high blood pressure.

It is estimated that every year about 14 million people in the world suffer events such as these, of which 5.5 million die and a high percentage is left with sequels for life.

In Colombia it is the second cause of death and only in the first half of 2018 some 7,429 people died from this cause, according to the Colombian Network against LCA.

This Tuesday, October 29, marks the world day of LCA and therefore, whatever the cause, it is important to consult urgently if one or more of the following symptoms occur.

Weakness or numbness:

When this occurs on the face, on an arm or on a leg, mainly on one side of the body.


If suddenly there are difficulties to speak or to understand what others say.

Vision problems:

Darkening or sudden loss of vision by one or several eyes.


If suddenly there is loss of balance or inability to coordinate.


Sudden inability to move or walk.


If it occurs unexpectedly and does not resemble any other pain that has been suffered.

It should be clarified that the search for help in a hospital must be urgent. The effectiveness of any medical intervention will depend on the time in which it is applied. In fact, the greatest likelihood of recovery of a stroke occurs when treatment is started in less than 4.5 hours after symptoms occur. If possible, attend a high complexity hospital once.

Some sequelae suffered by stroke survivors are difficulty coordinating body movements; trouble speaking, reading or writing; difficulty eating, personality or behavior changes, memory or thinking problems and visual disturbances.
