Understanding Stroke

Comprehensive medical information sourced from leading health organizations worldwide

What is a Stroke?

A stroke occurs when blood flow to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. Brain cells begin to die within minutes.

  • Ischemic Stroke (87%): Caused by blocked arteries in the brain
  • Hemorrhagic Stroke (13%): Caused by bleeding in or around the brain
  • TIA (Mini-Stroke): Temporary blockage that serves as a warning sign
  • Silent Stroke: No obvious symptoms but causes brain damage

Risk Factors

Understanding your risk factors is crucial for prevention. Many risk factors can be controlled through lifestyle changes and medical management.

  • High Blood Pressure: The #1 controllable risk factor
  • Smoking & Tobacco: Doubles stroke risk
  • Diabetes: Increases risk 2-4 times
  • High Cholesterol: Contributes to artery blockage
  • Obesity: Increases multiple risk factors
  • Physical Inactivity: Weakens cardiovascular system

Prevention Strategies

80% of strokes are preventable through lifestyle modifications and proper medical care. Small changes can make a significant difference.

  • Monitor Blood Pressure: Keep it below 120/80 mmHg
  • Exercise Regularly: 150 minutes moderate activity per week
  • Healthy Diet: Mediterranean or DASH diet patterns
  • Don't Smoke: Quit smoking and avoid secondhand smoke
  • Limit Alcohol: No more than 1-2 drinks per day
  • Manage Stress: Practice relaxation techniques

Warning Signs

Recognizing stroke symptoms quickly can save lives and reduce disability. Learn the signs and act immediately.

  • Face Drooping: Uneven or numb face, lopsided smile
  • Arm Weakness: One arm drifts downward
  • Speech Difficulty: Slurred or strange speech
  • Sudden Vision Loss: In one or both eyes
  • Severe Headache: Sudden, worst headache ever
  • Balance Problems: Sudden dizziness or coordination loss

Time is Brain

Every second counts during a stroke. Fast treatment can minimize brain damage and improve recovery outcomes significantly.

  • 1.9 Million: Neurons lost per minute during stroke
  • 3-4.5 Hours: Window for clot-busting drugs
  • 6-24 Hours: Extended window for some patients
  • 90 Minutes: Optimal treatment time for best outcomes
  • Golden Hour: First hour is most critical
  • Call Emergency Services: Fastest way to get expert stroke care

Treatment & Recovery

Modern stroke treatment has revolutionized outcomes. With proper care, many stroke survivors can return to normal or near-normal function.

  • Clot Removal: Mechanical thrombectomy procedures
  • Medications: tPA and other clot-busting drugs
  • Rehabilitation: Physical, occupational, speech therapy
  • Stroke Centers: Specialized care facilities
  • Recovery Timeline: Varies from weeks to years
  • Neuroplasticity: Brain's ability to rewire itself

B

Balance

Sudden loss of balance, coordination, or dizziness. Is the person having trouble walking or staying upright?

E

Eyes
