The 4 types of stroke (symptoms and causes)

Blows or blows they are the leading cause of death from disease in women and the second for men throughout Spain, reaching between 150 and 250 per 100,000 inhabitants in just one year. In addition, 24.7% of people who suffer from a stroke end up with some type of disability.

Fortunately, there are ways and treatments that can significantly lessen the damage caused by these strokes; But it is therefore necessary to identify the type of stroke that the person has suffered, Since each of them is characterized by different causes and consequences.

    What is a stroke?

    A stroke is a change in blood flow to the brain. When this happens, the brain stops receiving the oxygen it needs to function and the affected areas begin to die off.

    The effects of this type of accident can be damaging to the person, affecting the whole body. These consequences can range from vision problems to varying degrees, speech disorders, cognitive deficits or motor problemsEven bodily paralysis also to varying degrees.

    Strokes are also part of a wide range of changes in brain function, such as stroke, stroke, stroke, stroke or stroke.

      Types of stroke

      There are two main distinctions in brain spills. One of them is ischemic stroke, which is the cause of 80% of strokes, while the other attacks are caused by the so-called hemorrhagic stroke.

      1. Ischemic stroke

      Ischemic stroke is the most common stroke. The cause is the formation or arrival of a blood clot that blocks or interferes with the flow of a blood vessel in the brain, interrupting the flow of blood to the brain.

      In a few minutes brain cells start to die due to lack of oxygen and nutrients, leading to one of the consequences mentioned above.

      The symptoms that a person suffers from ischemic stroke are:

      • Weakness or numbness of the face, arm or leg
      • Confusion and problems speaking or understanding
      • Sudden vision problems
      • Sudden, severe headache with no apparent cause

      Likewise, transient ischemic attacks (TIAs) exist, Also known as mini-apoplexies. Transient ischemic attack is characterized by symptoms similar to those of ischemic effusion, but without its persistent effects. Suffering from one of these attacks can be the prelude to a more severe ischemic attack, so knowing how to correctly identify it is very important.

      In addition, ischemic strokes can be divided into two subgroups and categories: thrombotic strokes and embolic strokes.

      Thrombotic stroke

      Thrombotic spills are strokes caused by a blood clot called a thrombus, which starts in the arteries that supply blood to the brain.

      Usually, symptoms of this type of spill appear suddenly, especially during sleeping hours or in the morning. However, at other times, symptoms appear gradually over hours or days, in which case it is an active stroke.

      This subclass of stroke is common in older people, who have high cholesterol levels and arteriosclerosis.

      Embolic stroke

      Unlike the thrombotic attack, embolic strokes are the result of a piston. A blood clot that starts all over the body and is carried to the brain through the bloodstream is called a plunger.

      These attacks can also appear suddenly and are characteristic in people with heart disease or have had any type of heart surgery.

      2. Hemorrhagic stroke

      Being the less common accident subtype, hemorrhagic stroke is caused by a broken or sprained blood vessel, resulting in bleeding inside the brain and destruction of brain cells.

      This type of hemorrhagic accident usually occurs in people with high blood pressure, this blood pressure constricts the artery walls to break them.

      Likewise, another fairly common cause is the so-called aneurysm, A fragile point in the artery walls that is arched, due to the pressure with which the blood circulates, until it finally breaks and causes the spillage. These aneurysms can be congenital and be present from birth, or can be due to disorders such as hypertension or arteriosclerosis.

      Symptoms of a stroke appear suddenly. These symptoms include:

      • Muscle weakness and / or numbness in any part of the body
      • Sight problems
      • Speech disorders
      • Agnosia
      • Sudden headache of no known origin
      • Scared of heights
      • Fainting and dizziness
      • Coordination issues
      • Difficulty swallowing
      • drowsiness

      Like an ischemic stroke, there are two subtypes of hemorrhagic strokes: Intracerebral and subarachnoid hemorrhages.

      Intracerebral hemorrhage

      Intracerebral hemorrhage it consists of bleeding from the veins or arteries inside the brain. Usually, bleeding occurs suddenly and progresses very quickly; without producing any warning signals and being so severe that it can lead to coma or even death.

      The most common cause of this type of intracerebral hemorrhage is hypertension, which is high blood pressure.

      Subarachnoid hemorrhage

      In hemorrhages of this type the spill or bleeding is located in the subarachnoid space. It is between the brain and the membranes that cover them, called the meninges. The main causes of these strokes are two:

      • Existence or appearance of an aneurysm.
      • arteriovenous malformations (AVM). These malformations are part of a congenital alteration that causes the appearance of webs and tangled networks of veins and arteries.
