  1. Stroke: A Speaker’s Outline Developed by: The American Stroke Association Updated 4.19.2011

  2. What Is a Stroke? A brain injury caused when a blood vessel to the brain becomes blocked our bursts, cutting off blood flow

  3. What Is Stroke’s Impact? • Stroke is the third leading cause of death in the United States • About 795,000 Americans suffer a stroke each year (that’s a stroke every 40 seconds) • 77% are new strokes and 23% are recurrent strokes • Stroke kills more than 137,000 people in a year. ( that’s a death every 4 minutes)

  4. What Is Stroke’s Impact? (cont’d) • Stroke is a leading cause of serious, long-term disability • 40% of Stroke deaths occur in males, and 60% in females. • Americans paid about $73.7 billion for stroke-related medical costs in 2010

  5. What Are the Types of Stroke? • Ischemic (Blockage) 87% Caused by a blockage in the blood vessels to the brain • Hemorrhagic (Bleeding) 13% Caused by burst or leaking blood vessels in the brain

  6. What Causes Ischemic Stroke ? • Fatty deposits line the blood vessel wall • Thrombus: A blood clot forms at the fatty deposit • Embolus: A travelingparticle gets stuck in a small vessel

  7. Clot-caused Stroke by Age, Sex and Race Annual rate of first cerebral infarction by age, sex and race (Greater Cincinnati/Northern Kentucky Stroke Study: 1993-94). Source: Unpublished data from the GC/NKSS; Kissela et al., Stroke. 2004;35:426-31.

  8. What Causes Hemorrhagic Strokes? A weakened blood vessel ruptures • Aneurysms: Ballooning of a weakened spot of a blood vessel • Arteriovenous Malformations (AVMs): Cluster of abnormal blood vessels

  9. Hemorrhagic Stroke by Age, Sex and Race Annual rate of first intracerebral hemorrhage by age, sex and race (Greater Cincinnati/Northern Kentucky Stroke Study: 1993-94).Source: Kissela et al., Stroke. 2004;35:426-31.

  10. What Parts of theBrain Can Stroke Affect?

  11. What Are the Effects of Stroke? • Right Brain

  12. What Are the Effects of Stroke? • Left Brain

  13. Stroke Warning Signs • Sudden weakness or numbness of the face, arm or leg, especially on one sideof the body • Sudden confusion, trouble speaking or understanding • Sudden trouble seeing in one or both eyes • Sudden trouble walking, dizziness, loss of balance or coordination • Sudden, severe headaches with no known cause

  14. Learn to recognize a stroke.Time lost is brain lost. • If you notice one or more of the stroke warning signs, GET HELP IMMEDIATELY! • Stroke is an emergency – CALL 9-1-1.

  15. Transient Ischemic Attacks(TIAs) • TIAs are “warning strokes” that can happen before a major stroke • They occur when blood flow through a brain artery is briefly blocked or reduced

  16. Transient Ischemic Attacks(TIAs) • TIA symptoms are temporary but similar to those of a full-fledged stroke • A person who has a TIA is 9.5 times more likely to have a stroke • A TIA is a medical emergency

  17. Age Heredity (family history) and race Sex (gender) Prior stroke, TIA or heart attack Stroke Risk Factors That Cannot Be Treated

  18. Stroke Prevalence by Age & Sex Prevalence of stroke by age and sex(NHANES: 1999-2004). Source: NCHS and NHLBI.

  19. Stroke Risk FactorsThat Can Be Treated • High blood pressure • Tobacco use • Diabetes • Carotid or other artery disease • Atrial fibrillation • Other heart disease

  20. Stroke Risk FactorsThat Can Be Treated (cont’d) • Sickle Cell Disease (Sickle Cell Anemia) • High blood cholesterol • Poor diet • Physical inactivity • Obesity

  21. Stroke Risk by Levelsof Risk Factors A B C D E F Systolic BP* 95-105 130-148 130-148 130-148 130-148 130-148 Diabetes No No Yes Yes Yes Yes Cigarettes No No No Yes Yes Yes Prior Atrial Fib.

  22. Less Well-Documented Stroke Risk Factors • Geographical location • Socioeconomic factors • Excessive alcohol intake • Certain kinds of drug abuse

  23. How Can You ReduceYour Risk of Stroke? • Control high blood pressure • Don’t smoke • Consume less sodium • Lower cholesterol • Lose excess weight • Be physically active

  24. Other Actions That Will ProbablyReduce Stroke Risk • Limit alcohol intake • Don’t use illicit drugs • Women who smoke or have a history of blood clots should not take oral contraceptives • Look for signs of sleep-disordered breathing

  25. How Are Strokes Treated? • Ischemic Stroke • Acute treatment • Clot-buster, e.g., t-PA • Interventional procedures • Preventive treatment • Anticoagulants (warfarin) • Antiplatelet agents (aspirin) • Carotid endarterectomy • Angioplasty/stents • Hemorrhagic Stroke • Surgery • Endovascular procedures, e.g., “coils”

  26. Rehabilitation • If you have a stroke, start a rehabilitation program as soonas you can • Rehabilitation may focus on: • Self-care • Mobility      • Communication • Cognitive skills • Social skills

  27. Types of Rehabilitation Programs • Acute care and rehabilitation hospitals • Long-term nursing care facilities    • At home, through home health agencies          • Outpatient facilities

  28. Physicians Rehabilitation nurses Physical therapists Speech/language therapists Rehabilitation Specialists

  29. Rehabilitation Specialists (cont’d) • Audiologists • Occupational therapists • Physiatrists • Psychologists / psychiatrists
