What is Stroke?

21:56 - 4 May , 2021


Also known as a cerebrovascular accident or cerebral infarction, a stroke occurs when blood partially or totally stops reaching a specific area of the brain, preventing oxygenation and causing the death of neurons. Due to this, it is of the utmost importance to act quickly and receive care as soon as possible, in this way, brain damage is reduced.

There are two types of strokes: 

  • Ischemic stroke: it is the most frequent and occurs when there is a partial or total blockage of the blood vessels due to clots or fatty matter formations.
  • Hemorrhagic stroke: occurs when one of the cerebral blood vessels breaks or has a leak, the main causes being hypertension, blows to the head, aneurysm, and prolonged treatment with anticoagulants.

Potential risks:

  • Sedentary lifestyle.
  • Obesity.
  • Alcoholism, smoking, and drug addiction.
  • High blood pressure.
  • High cholesterol and triglycerides.
  • Diabetes.
  • Cardiovascular diseases.
  • Sleep apnea.
  • Having family members who have had a stroke. 

Signs and symptoms Stroke

Special care must be taken to identify the symptoms of a stroke in order to act immediately and minimize the possible consequences of this condition.

The most frequent signs are:

  • Confusion, speech and understanding problems.
  • Weakness, numbness, or tingling in the face, arms, or legs. 
  • Visual impairment in which you can lose vision in one or both eyes, which can manifest as double vision, lack of focus, or shadowing. 
  • Acute sudden migraine, along with nausea, vomiting, and dizziness. 
  • Lack of balance and coordination and walking difficulties.

Diagnosis and treatment Stroke

Upon arrival at the Emergency Room, the multidisciplinary team will perform imaging studies such as computed tomography, MRI, and ultrasound to determine the type of stroke you are suffering and establish the ideal treatment for you.

The treatment goal for an ischemic stroke is to unclog the affected blood vessels allowing a normal blood flow. To achieve this, intravenous medications are usually used to break up the clot or perform an endovascular procedure to directly unclog the affected blood vessel.

As for hemorrhagic stroke, the treatment purpose is to stop the bleeding and reduce the brain pressure it causes. You may be given pressure-reducing drugs and antispasmodics, but if the bleeding area is large, surgery will be needed to extract the blood and release intracranial pressure. Currently there are minimally invasive surgical techniques that facilitate this procedure.
