HealthSketch on Stroke

Introduction to Stroke

  • Definition: The term "stroke" refers to a sudden medical condition where blood flow to the brain is interrupted, causing brain cell damage.
  • Stroke Statistics:
    • Over 15 million strokes occur worldwide annually.
    • 5 million fatalities and another 5 million disabled from strokes each year.
    • Most strokes occur in individuals over 65, but younger people can also be affected.

Understanding Stroke

  • What is a Stroke?
    • Occurs when blood flow to the brain is cut off.
    • Symptoms depend on the affected brain area, including:
      • Drooping face
      • Weakness in arms/legs
      • Difficulty speaking
      • Changes in vision, balance, and memory loss.

Recognizing Stroke Symptoms (FAST)

  • Face: Check for drooping on one side.
  • Arms: Look for weakness or inability to lift both arms.
  • Speech: Is speech slurred?
  • Time: Call an ambulance if any signs are observed.

Types of Stroke

  • Ischaemic Stroke:

    • Most common type; caused by blockages in the blood vessels due to fatty build-up (similar to a heart attack).
    • Clots may form in the brain or travel from elsewhere (e.g., neck or heart).
    • Treatment: Clot-busting medication (thrombolysis) if detected early; otherwise, aspirin may be used.
  • Haemorrhagic Stroke:

    • Occurs when a blood vessel bursts, causing blood to leak into or around the brain.
    • May lead to swelling and require surgical intervention.

Transient Ischemic Attack (TIA)

  • Mini-stroke where symptoms last less than 24 hours; may only last a few minutes.
  • Sign of high stroke risk; immediate hospital visit is essential.

Stroke Rehabilitation

  • Importance of rehabilitation to recover lost abilities:
    • Dieticians for swallowing difficulties
    • Speech and language therapists for communication issues
    • Physiotherapists and occupational therapists for mobility and daily tasks
    • Counselors for emotional support and addressing dependency issues.

Stroke Prevention Strategies

  • Key steps to reduce stroke risk:
    • Lower high blood pressure
    • Stop smoking
    • Reduce cholesterol levels
    • Increase physical activity
    • Healthy eating
    • Limit alcohol consumption
    • Manage diabetes effectively.
