Cerebral stroke

A stroke, is a medical condition that occurs when blood flow to the brain is suddenly interrupted.

Cerebral stroke

A stroke, also known as a cerebrovascular accident (CVA) or stroke, is a medical condition that occurs when blood flow to the brain is suddenly interrupted. This interruption of blood flow can be caused by a blood clot blocking an artery in the brain (ischemic stroke) or by a ruptured blood vessel in the brain (hemorrhagic stroke).


The brain is one of the most important organs in the human body, and when it doesn't get enough blood and oxygen, brain cells can die in a matter of minutes. For this reason, it is essential to act quickly when faced with the symptoms of a stroke.



What are the symptoms of a cerebral infarction?


Symptoms can vary depending on the severity and location of the event. Some of the more common symptoms include:


  • Loss of muscle strength or coordination on one side of the body

  • Difficulty speaking or understanding speech

  • Loss of vision or blurred vision in one or both eyes

  • Sudden severe headache

  • Dizziness or loss of balance



Act FAST



How can you tell if someone is having a stroke? The FAST test can help you identify the most common signs of this medical emergency; to recognize it, consider these questions:

  • Facial weakness: Can the person smile? Has their mouth or eye drooped?

  • Arm weakness: Can the person raise both arms?

  • Speech problems: Can the person speak clearly and understand what you say?

  • Time to call the ER: If you notice any of these signs, you should call emergency services immediately.


What are the types of strokes?


There are different types of stroke, each with unique characteristics and symptoms. The 3 main types of strokes are:


  • Ischemic infarction is the most common type and accounts for about 80% of cases of stroke. It occurs when a blood clot clogs or clogs a blood vessel in the brain, disrupting blood flow and depriving brain cells of needed oxygen and nutrients.

  • Hemorrhagic stroke occurs when a blood vessel in the brain ruptures and bleeds into the brain, which can cause severe brain damage.

  • A transient ischemic attack (TIA), or also called a "micro-infarction," occurs when the blood supply to the brain is temporarily blocked, increasing the risk of suffering a stroke in the future. Although the damage to brain cells is not permanent, it can be a warning sign of an impending stroke.



Who is at risk?


There are several risk factors that can increase the probability of suffering a stroke. Some of the more common risk factors include:

  • Old age

  • Arterial hypertension

  • Diabetes

  • High cholesterol

  • Smoking

  • Obesity

  • Family history of stroke or cardiovascular disease


It is important to note that a stroke can occur in people of all ages, including children and young people. Therefore, it is essential to maintain a healthy lifestyle and seek regular medical attention to minimize the risk of developing this condition.



How can a stroke be prevented?


To prevent a stroke, it's crucial that you know your risk factors, follow your doctor's recommendations, and adopt a healthy lifestyle. These are the best measures you can take to prevent this condition:

  • Control blood pressure and cholesterol levels

  • Keep a healthy weight

  • Do not smoke or quit

  • Exercise regularly

  • If you have it, control your diabetes

  • Reduce daily stress levels

  • Take medications as prescribed


Immediate attention is key to prevent complications from a stroke, so it's crucial to consult go to the emergency room if you suspect or experience any stroke-related symptoms.
