What is a stroke? What Are the Symptoms of Stroke?

The death of oxygen-deprived brain tissue as a result of a sudden halt of blood flow is referred to as a stroke. Every year, 17 million individuals worldwide suffer from a stroke, implying that one person dies from a stroke every minute. Furthermore, 6 million individuals die from strokes each year around the world. In Eastern Europe, Asia, and the United States, stroke is the leading cause of death. When you consider that 3 million people died worldwide as a result of COVID-19 in the first year of the pandemic, you can see how significant and high the annual loss of 6 million people due to stroke is.


Strokes are also the primary cause of disability. Every year, 30% of stroke patients require support with everyday tasks, 20% can stand and walk with assistance, and 16% must be admitted to a care facility. Every year, around 100 thousand ischemic and 40 thousand hemorrhagic strokes occur.

What is the cause of a stroke?

Diabetes, hypertension, smoking, obesity, high cholesterol, an irregular diet, a sedentary (or less active) lifestyle, excessive alcohol consumption, drug use, heart rhythm disorders, valve diseases, heart failure, cardiovascular diseases, atherosclerosis, or artery narrowing, are all risk factors for stroke. A stroke risk is created when one or more of these factors are present.


To abstain from consuming alcohol and cigarettes, or to minimize the amount consumed if this is not practicable (smoking and high alcohol consumption increase the risk of stroke 2-3 times).

  • With good medical intervention, reducing or even eradicating chronic diseases and any risk factors that may raise the chance of stroke.
  • Adequate internal and cardiological issues therapy by relevant specialties
  • Evaluation of stroke risk factors for each patient individually, which is an important topic in neurology. The neurology department can do proper examinations and investigations to prevent stroke before it occurs.

What are the different types of strokes?

Ischemic stroke is caused by a blockage or reduced blood flow in the arteries that supply that location. It’s the leading cause of stroke. There are three types of ischemic stroke:

  • TIA (transient ischemic attack): brief attacks can last anywhere from a few minutes to 24 hours and resolve completely, although this attack could be a precursor to a bigger catastrophe.
  • Complete infarct: causes permanent tissue damage, which heals over time. It frequently lasts longer than three weeks and does not fully heal.
  • Reversible ischemic neurologic deficit: This can last anywhere from 24 to 3 weeks. There is no tissue death; the organ is fully functional.

Hemorrhagic stroke is tissue damage produced by bleeding that puts pressure on the brain and its environs.

How do you know if you’ve had a stroke?

A stroke can strike at any time and for no apparent reason. Numbness-numbness, loss of awareness or disorder, speech loss or disorder, trouble in comprehending, facial shift, inability to walk or imbalance, dizziness, severe headache, memory loss One or more of the symptoms, such as swallowing difficulties, blindness, or double vision, may be present at the same time.

What is the treatment for a stroke?

Today, because stroke is one of the diseases that can be treated promptly, medical help should be sought as soon as possible by dialing 112 as soon as a stroke is suspected. Medical intervention during the first two hours or up to three hours (thrombolytic therapy, tPA, and, if necessary, interventional treatment in big vascular occlusions (mechanical thrombectomy)) saves lives and can avoid permanent impairment.

Furthermore, quick neurology department examination of individuals with transient ischemic attack is critical in preventing the creation of a permanent stroke-infarct. Appropriate and consistent post-stroke medical care and treatment, as well as physical therapy and rehabilitation programs for lasting physical difficulties (paralysis, loss of balance, inability to speak, and so on) should not be overlooked.

In adults over 60, regular exercise is the greatest way to prevent stroke. Walking in the open and fresh air on a regular basis, as well as regular arm, leg, waist, and neck motions at home, are encouraged. In addition to regular exercise, it’s critical to pay attention to sleep patterns and incorporate a Mediterranean-style diet (low salt and low fat eating habits, plenty of vegetables and fruits) into one’s diet.
