Transcript of "Neurological Disorders part 1"

  1. 1. Medical Nutrition Therapy in Neurological Disorders Part 1
  2. 2. Nutrition and Neurologic Disease <ul><li>May have nutritional etiologies resulting from deficiency or excess </li></ul><ul><li>May be nonnutritional in origin but have significant nutritional implications </li></ul>
  3. 3. Stroke Statistics <ul><li>Stroke is the third leading cause of death ranking behind diseases of the heart and cancers </li></ul><ul><li>Killed 150,147 people in 2004; females accounted for 60.9 percent of stroke deaths. </li></ul><ul><li>About 5,700,000 stroke survivors are alive today. 2,400,000 are males and 3,300,000 are females. </li></ul><ul><li>Data from GCNKSS studies show that about 700,000 people suffer a new or recurrent stroke each year. About 500,000 of these are first attacks and 200,000 are recurrent attacks. (GCNKS studies) </li></ul>http://www.americanheart.org/presenter.jhtml?identifier=4725accessed online 11-16-07
  4. 4. Stroke Statistics <ul><li>From 1992 to 2002 the death rate from stroke declined 13.8 percent, but the actual number of stroke deaths rose 6.9 percent .  </li></ul><ul><li>A leading cause of functional disability – 15-30% permanently disabled </li></ul>Primary Prevention of Ischemic Stroke, AHA/ASA Guideline, Stroke 2006;37:1583-1633, accessed online 11-16-06

  6. 6. Pathophysiology of Stroke <ul><li>85% of strokes caused by a thromboembolic event (related to atherosclerosis, hypertension, diabetes, gout) </li></ul><ul><ul><li>Embolic stroke: cholesterol plaque is dislodged from vessel, travels to the brain, blocks an artery </li></ul></ul><ul><ul><li>Thrombotic stroke: cholesterol plaque within an artery ruptures, platelets aggregate and clog a narrow artery </li></ul></ul>
  7. 7. Nutrition-Related Factors and Stroke Risk (BMI = body mass index)
  8. 8. Thromboembolic Stroke
  9. 9. Hemorrhagic Stroke <ul><li>Intraparenchymal hemorrhage: prevalence of hypertension is 80%; vessel inside the brain ruptures </li></ul><ul><li>Subarachnoid hemorrhage (SAH): ruptured aneurism in the subarachnoid space; or due to head trauma </li></ul><ul><li>15% of all strokes </li></ul>
  10. 10. Hemorrhagic Stroke
  11. 11. Medical Treatment for Stroke <ul><li>Thrombolytic or “clot-busting” drugs to restore perfusion to affected areas within 6 hours of onset of stroke </li></ul><ul><li>Controlling intracranial pressure (ICP) while maintaining sufficient perfusion of the brain </li></ul>
  12. 12. Nutritional Management in Stroke <ul><li>Primary prevention </li></ul><ul><li>Acute management (screening for dysphagia and nutritional risk) </li></ul><ul><li>Intervention for swallowing disorders via consistency changes </li></ul>
  13. 13. AHA Guidelines for Primary Prevention of CVD and Stroke: 2006 Update <ul><li>Smoking: complete cessation (Class I, evidence level B </li></ul><ul><li>Avoid exposure to environmental tobacco smoke (Class IIA, evidence C) </li></ul><ul><li>BP control: goal <140/90 mmHg with lower targets in some subgroups (<130/80 in diabetes) </li></ul>Goldstein et al, Primary Prevention of Ischemic Stroke, Stroke 2006;37:1583-1633)

( Circulation. 2002;106:388-391.)
  16. 16. Lipids and Stroke <ul><li>Cholesterol is a very weak risk factor for ischemic stroke, in contrast to CAD </li></ul><ul><li>Cholesterol reduction with diet and nonstatin drugs is not effective in stroke prevention, although reductions in levels of cholesterol are modest </li></ul><ul><li>Statins produce a statistically significant 25% reduction in the risk of stroke </li></ul>Briel M, et al Am J Med 2004;117:596-606

( Stroke. 2005;36:916.)
  25. 25. FOOD (Feed or Ordinary Diet) Trial <ul><li>Found no benefit to routine oral supplementation of post-stroke patients who had not been identified as malnourished (1) </li></ul><ul><li>Early tube feeding was associated with an absolute reduction in risk of death of 5.8% (p=0.09) and a reduction in death or poor outcome of 1.2% (p=0.7) (2) </li></ul><ul><li>PEG feeding (vs NG) was associated with an absolute increase in risk of death of 1.0%, p=0.9) and an increased risk of death or poor outcome of 7.8% (p=0.05). </li></ul>1: Lancet. 2005 Feb 26-Mar 4;365(9461):755-63. 2: Lancet. 2005 Feb 26-Mar 4;365(9461):764-72
  26. 26. AHA Guidelines for Early Management of Pts with Ischemic Stroke <ul><li>A poor nutritional status was associated with an increased risk of infections including pneumonia, gastrointestinal bleeding, and pressure sores. </li></ul><ul><li>These data provide a strong rationale for assessment of the patient’s nutritional status at the time of admission. </li></ul>AHA/ASA Guidelines for the Early Management of Patients with Ischemic Stroke.
