Brain Stroke: Causes, Symptoms, and Essential Steps for Treatment and Prevention

Created by Doctor Chloe in Brain and Nervous System, 5 months ago

A brain stroke, also known as a cerebrovascular accident, occurs when the blood supply to a part of the brain is abruptly interrupted or reduced. This interruption in blood flow can lead to severe damage to brain cells and potentially life-altering consequences.

 Understanding the causes, recognizing the symptoms, and taking immediate action are crucial for effective management of brain strokes. In this article, we will delve into the details of brain strokes and provide essential information on what you need to know.

What is a brain stroke?

A brain stroke refers to the sudden disruption of blood flow to the brain, resulting in the deprivation of oxygen and nutrients to brain cells. This can be caused by two main factors:

a) Blocked cerebral vessels: This occurs when the blood vessels in the brain become narrow or obstructed due to conditions such as atherosclerosis (build-up of plaque in the arteries) or when blood clots or plaques from other parts of the body travel to the cerebral arteries and cause blockages.

b) Ruptured blood vessel: A sudden, excessive increase in blood pressure or the rupture of a cerebral aneurysm (an abnormal bulge in a brain blood vessel) can lead to a broken blood vessel in the brain.

There is also a rare occurrence known as transient ischemic attack (TIA), where blood flow to the brain is temporarily disrupted, resulting in stroke-like symptoms. However, in TIAs, the blood vessels self-open, and complete recovery typically happens within 24 hours.

Risk factors for stroke:

Several risk factors increase the likelihood of experiencing a stroke. These include:

  • High blood pressure (hypertension)
  • Diabetes
  • Atherosclerosis (hardening of the arteries)
  • High blood cholesterol levels
  • Certain heart conditions (e.g., heart valve disease, atrial fibrillation)
  • Smoking
  • Excessive alcohol consumption
  • Blood clotting disorders
  • Obesity
  • Sedentary lifestyle

Understanding and managing these risk factors can significantly reduce the chances of experiencing a stroke.

Symptoms of a stroke:

Recognizing the symptoms of a stroke is crucial for timely intervention. Common signs and symptoms include:

Sudden weakness or numbness in the arms and legs, particularly on one side of the body (hemiparesis)
Sudden blurred or loss of vision
Sudden difficulty speaking, slurred speech, or trouble understanding others
Sudden, severe headache with no known cause
Sudden dizziness, loss of balance, stumbling, or falling without explanation

Other symptoms that may occur include sudden hiccups, nausea, and vomiting without an apparent cause. It is important to note that these symptoms usually occur suddenly and without warning.

Immediate actions when a loved one has a stroke:

If someone you know is experiencing a stroke, it is essential to take immediate action. Here are some steps to follow:

  • Support the patient to prevent falls, as self-falling can cause additional brain injury.
  • If the patient is conscious, have them lie quietly and immediately call for an ambulance to transport them to the nearest specialized hospital.
  • If the patient is unconscious, assess their breathing. If the patient is not breathing or experiencing abnormal breathing patterns, it is necessary to provide artificial respiration. This can be done by blowing into the patient's mouth while ensuring their airway is open and protected. Seek medical assistance as soon as possible.
What not to do during a stroke:
It is crucial to avoid certain actions when someone is experiencing a stroke. These include:
Refrain from attempting to treat the patient yourself, such as using acupressure, acupuncture, or blowing air, as these actions may unintentionally worsen the condition. 

Stroke can manifest in two forms:
a) Brain bleeding due to the rupture of blood vessels.
b) Cerebral infarction due to vessel occlusion.

These two types of strokes have different causes, mechanisms, and treatments. Therefore, it is crucial to consult specialized doctors in facilities equipped with modern diagnostic tools to accurately identify the type of stroke and determine the appropriate treatment approach.

Avoid moving the patient's head and neck in case of a fall or accident, as this can cause secondary spinal injuries. Instead, place the patient in a comfortable position and loosen any tight clothing.

Do not allow the patient to eat, drink, or vomit to prevent aspiration. Inhalation of vomit or food into the airway can be extremely dangerous.

Do not administer aspirin or use antihypertensive drugs without proper medical guidance. Only use antihypertensive drugs if the patient's blood pressure exceeds 180/100 mmHg. It is essential to consult a healthcare professional before administering any medication.
Treatment and handling:

Immediate hospital admission is crucial for stroke patients to receive prompt diagnosis and treatment. In the case of a stroke, time is of the essence, as it allows for the timely management of blood vessel blockages or ruptures, thereby preventing complications and potential long-term disabilities such as paralysis or hemiplegia. 

Specialized hospitals equipped with modern diagnostic tools can accurately diagnose vascular occlusions or ruptures, allowing for the administration of appropriate medications to dissolve blood clots or interventions to stop bleeding and promote speedy recovery.


Preventing strokes involves adopting proactive measures to reduce risk factors. Consider the following prevention strategies:

  • Control and manage risk factors such as high blood pressure, diabetes, high cholesterol levels, smoking, and obesity. Work closely with healthcare professionals to monitor and treat these conditions effectively.
  • Engage in regular exercise appropriate for your health condition, ensuring you do not overexert yourself.
  • Manage stress levels and avoid sudden changes in posture, extreme temperature shifts, or drastic changes in pressure.
  • Individuals with high blood pressure should limit alcohol consumption and adhere to prescribed blood pressure medications.
  • Individuals with artificial heart valves should diligently follow the prescribed anticoagulant regimen as directed by a specialist.

Brain strokes are medical emergencies that can result in debilitating consequences such as paralysis or hemiplegia. To mitigate the risk of strokes, it is essential to prioritize prevention by managing risk factors effectively. 

When a stroke occurs, swift action is critical, including seeking immediate medical attention for proper diagnosis and treatment. By understanding the causes, recognizing the symptoms, and taking appropriate preventive measures, we can work towards reducing the incidence and impact of brain strokes and promoting better overall health and well-being.
