Although stroke is often perceived as a sudden event, in many cases the body sends warning signs weeks beforehand. Recognizing these symptoms, responding promptly, and adopting preventive measures can make the difference between a favorable recovery and serious consequences.

What is a stroke?
A stroke is a sudden disruption of blood flow in the brain. It can be caused by a blockage (ischemic) or a ruptured blood vessel (hemorrhagic) . In both cases, nerve cells die rapidly due to the lack of oxygen, which poses a risk of permanent side effects or even death.

There is also transient ischemia (TIA) , which is a warning: the symptoms disappear, but it warns of an imminent risk of a major episode.

10 early warning signs
These symptoms can appear up to a month before the stroke. If you experience one or more, seek immediate medical attention:
