What happens when a person gets brain stroke?

  • July 13, 2023

A brain stroke, also known as a cerebrovascular accident (CVA), occurs when the blood supply to a part of the brain is disrupted, leading to damage or cell death in that area. The two main types of strokes are ischemic strokes and hemorrhagic strokes, and their causes differ.

  1. Ischemic Stroke: This type of stroke is the most common, accounting for about 85% of all strokes. It occurs when a blood clot or plaque buildup blocks or narrows a blood vessel supplying the brain, leading to reduced blood flow. The causes of ischemic stroke include:

a. Thrombosis: A blood clot forms in an artery supplying the brain, often due to atherosclerosis (hardening and narrowing of the arteries) or other vascular diseases.

b. Embolism: A blood clot or plaque fragment, which typically forms in another part of the body (e.g., the heart), travels through the bloodstream and lodges in a brain artery, blocking blood flow.

c. Systemic hypoperfusion: Generalized decrease in blood supply to the brain, usually caused by low blood pressure or decreased cardiac output. This can occur in conditions such as severe heart failure or shock.

  1. Hemorrhagic Stroke: This type of stroke occurs when a blood vessel in the brain ruptures, leading to bleeding into or around the brain tissue. The causes of hemorrhagic stroke include:

a. Intracerebral Hemorrhage: Bleeding occurs within the brain tissue itself, often due to the rupture of a weakened blood vessel, such as an aneurysm or arteriovenous malformation (AVM).

b. Subarachnoid Hemorrhage: Bleeding occurs in the space between the brain and the thin tissues that cover it, usually caused by the rupture of an aneurysm.

Various risk factors increase the likelihood of experiencing a stroke, including high blood pressure, smoking, diabetes, high cholesterol, obesity, sedentary lifestyle, family history of stroke, age, and certain medical conditions. It’s essential to manage these risk factors and adopt a healthy lifestyle to minimize the chances of having a stroke. Prompt medical attention is crucial in case of stroke symptoms, as early treatment can help minimize brain damage and improve outcomes.

When a person experiences a brain stroke, the specific symptoms and their severity can vary depending on the area of the brain affected and the extent of the damage. The symptoms typically appear suddenly and may include:

  1. Physical Symptoms:
    • Weakness or paralysis on one side of the body, often affecting the face, arm, or leg.
    • Numbness or loss of sensation on one side of the body.
    • Difficulty in walking, loss of coordination, or balance problems.
    • Trouble speaking or understanding speech.
    • Vision problems, such as blurred or double vision.
    • Severe headache with no apparent cause.
  2. Cognitive and Emotional Symptoms:
    • Confusion or disorientation.
    • Difficulty in speaking or understanding language.
    • Memory problems or trouble with reasoning.
    • Emotional changes, including sudden mood swings, depression, or anxiety.
  3. Other Symptoms:
    • Dizziness or vertigo.
    • Loss of consciousness or fainting.
    • Difficulty swallowing or sudden onset of dysphagia.
    • Loss of bladder or bowel control.

It’s important to note that not all stroke symptoms may be present in every case, and the severity can vary. If someone experiences any of these symptoms, it is crucial to seek immediate medical attention, as early diagnosis and treatment can significantly improve the chances of recovery and minimize long-term complications.

While it’s not possible to completely eliminate the risk of having a brain stroke, there are several steps you can take to reduce the likelihood of experiencing one. Here are some preventive measures:

  1. Maintain a Healthy Lifestyle:
    • Control blood pressure: Keep your blood pressure within a healthy range (typically below 120/80 mmHg) through lifestyle modifications, such as a balanced diet, regular exercise, limited salt intake, and managing stress.
    • Quit smoking: Smoking increases the risk of stroke. If you smoke, seek assistance to quit, such as counseling, nicotine replacement therapy, or medication.
    • Manage diabetes: Keep your blood sugar levels under control through proper management of diabetes, including medication, regular monitoring, and a healthy diet.
    • Maintain a healthy weight: Aim for a body mass index (BMI) within the recommended range (18.5-24.9). This can be achieved through a combination of balanced eating and regular physical activity.
  2. Adopt a Healthy Diet:
    • Consume a diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit saturated fats, trans fats, cholesterol, and sodium.
    • Increase intake of foods containing potassium, such as bananas, spinach, and sweet potatoes, as they help regulate blood pressure.
    • Limit alcohol consumption: Moderate alcohol consumption is defined as up to one drink per day for women and up to two drinks per day for men.
  3. Engage in Regular Physical Activity:
    • Strive for at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity exercise per week. This can include activities like brisk walking, jogging, cycling, swimming, or dancing.
    • Incorporate strength training exercises at least twice a week to improve overall fitness.
  4. Manage Underlying Medical Conditions:
    • Follow your healthcare provider’s recommendations for managing conditions like high cholesterol, atrial fibrillation, heart disease, and other cardiovascular diseases.
    • Take prescribed medications regularly and attend medical check-ups as advised.
  5. Be Aware of Stroke Risk Factors:
    • Understand your personal risk factors for stroke, such as age, family history, and genetic predisposition. Discuss these factors with your healthcare provider to determine the best preventive strategies for your situation.
  6. Be Prepared and Act Quickly:
    • Learn to recognize the signs and symptoms of stroke. Remember the acronym FAST: Face drooping, Arm weakness, Speech difficulty, Time to call emergency services.
    • If you or someone around you experiences stroke symptoms, call emergency services immediately for prompt medical attention. Time is critical in stroke treatment, and early intervention can help minimize damage.

It’s important to consult with your healthcare provider for personalized advice and to develop a comprehensive stroke prevention plan based on your individual health profile.

The treatment for stroke depends on the type of stroke, whether it is ischemic or hemorrhagic, and how soon medical intervention is sought. The primary goals of stroke treatment are to restore blood flow to the affected area of the brain, minimize further damage, and promote recovery. Here are the main treatment approaches for stroke:

  1. Ischemic Stroke Treatment:

a. Intravenous thrombolysis: If a patient arrives at the hospital within a few hours of symptom onset, a clot-dissolving medication called tissue plasminogen activator (tPA) may be administered intravenously to dissolve the blood clot causing the stroke.

b. Mechanical thrombectomy: In some cases, a procedure called mechanical thrombectomy may be performed. This involves using a catheter to remove the blood clot directly from the blocked blood vessel in the brain.

  1. Hemorrhagic Stroke Treatment:

a. Medical stabilization: The first step is to stabilize the patient’s condition and control bleeding, which may involve medications to lower blood pressure or procedures to repair ruptured blood vessels.

b. Surgery: In some cases, surgical intervention may be required to remove blood clots, repair blood vessel abnormalities, or relieve pressure on the brain caused by bleeding.

  1. Supportive Care and Rehabilitation:

a. After the acute treatment phase, stroke patients require supportive care and rehabilitation to promote recovery and maximize functional abilities. This may involve a multidisciplinary team of healthcare professionals, including physical therapists, occupational therapists, speech therapists, and rehabilitation specialists.

b. Rehabilitation typically includes exercises and therapies to help regain strength, coordination, mobility, speech, and cognitive abilities. The intensity and duration of rehabilitation depend on the individual’s needs and the extent of the stroke’s impact.

In addition to these treatments, stroke prevention strategies, such as managing risk factors and maintaining a healthy lifestyle, play a crucial role in reducing the risk of recurrent strokes.

It’s important to note that stroke treatment should be administered promptly. Recognizing the signs of stroke and seeking immediate medical attention by calling emergency services is crucial to increase the chances of successful treatment and minimize long-term disability.
