Stroke Detection and Prevention

According to the World Stroke Organisation, one in six people are at risk of suffering from stroke, and globally one person encounters a stroke every two seconds. According to Vietnam’s Ministry of Medicine, each year approximately 200,000 people in Vietnam suffer from a stroke, 50% of them die and 90% of stroke survivors live with neurological and motor conditions.

What is a stroke?

A stroke occurs when there is a sudden interruption of the blood supply to the brain, causing the part of the brain receiving the supply of blood from the arteries to be deprived of oxygen, and, as a result, the respective brain cells die within minutes. The patient might become paralyzed, or even die, depending on the part of the brain that has become damaged.

There are three types of stroke:

  • Cerebral Infarction: Caused by a blood clot that interrupts blood flow in the brain artery, accounting for about 85% of strokes.
  • Intracerebral Hemorrhage (also known as brain bleed): Caused by blood spilling into brain tissue, resulting in brain damage, accounting for about 15% of strokes.
  • Transient Ischemic Attack: Often referred to as a small stroke and only lasts a few minutes. It occurs when the blood supply to part of the brain is briefly blocked. It does not cause any obvious complications to the patient. However, this is a warning sign, suggesting a high risk of cerebral infarction.
Causes of stroke

There are many causes of stroke, the most common of which are; high blood pressure, lack of mobility, unhealthy diet, obesity, smoking, diabetes, heart disease, and drinking too much alcohol. Furthermore, genetic factors also increase the risk of stroke. If one of your family members suffered from a stroke in the past, it is best to do a stroke screening for prevention and early treatment.

Signs and Symptoms

Early detection of the signs of stroke is important to diagnosis and administer treatment. Adopting the F.A.S.T method is one way to do so.

F = Face: Face drooping, crooked smile, and the cleft is slightly skewed to one side

A = Arm: Numbness in the arm, difficulty moving or coordinating

S = Speech: Abnormal lisp, numbed tongue, difficulty in opening mouth and speaking

T = Time: When any of these signs suddenly occur, immediately call an ambulance, take the patient to the nearest hospital providing stroke treatment. The best time to deal with stroke is within the first 3-4 hours, preferably the first 2 hours. Patients should be admitted as soon as possible to avoid death and limit the potential of future conditions.
