Slide 1-

CHRONIC ILLNESS AND AGING
Slide 2-

CHRONIC ILLNESS: A long-lasting illness (in contrast to ACUTE illness, which is temporary) Most common in older adults Heart disease Cancer Cerebrovascular disease (stroke)
Slide 3-

HEART DISEASE: Principal cause of death among o.a.’s Accounts for significant morbidity, disablement & inactivity among o.a.’s Dominant factor--atherosclerosis (build-up of fatty deposits within arterial walls)
Slide 4-

Mechanism: Atherosclerotic buildup------> Narrowing of arteries supplying blood to the heart-----> ISCHEMIA (denial of adequate blood supply)
Slide 5-

Ischemic heart disease also known as: coronary heart disease (CHD) coronary artery disease A common form: myocardial infarction (heart attack) persistence of deficient blood supply, tissue dies. Dead area: an infarct
Slide 6-

Heart attack may also result from: Cardiac arrest-- some interruption of normal pattern of cardiac contraction Coronary thrombosis--sudden blockage of coronary artery with a blood clot Strenuous exercise resulting in suddenly increased need for O2
Slide 7-

Mortality associated with MI: Over 70--2x that under age 70 Symptoms of MI may differ in older people than in younger ones
Slide 8-

“…while complete absence of chest pain is very rare in acute myocardial infarction up to middle age, it is a ‘mundane occurrence’ in old people” “…only about 1/3 of elderly patients present with a classical prolonged episode of chest pain”. (Kart & Kinney, p. 111)
Slide 9-

Heart Disease: Modifiable Risk Factors: Cigarette smokers 2x MI rate of non-smokers High BP High serum cholesterol levels Diabetes Obesity Sedentary lifestyle
Slide 10-

Healthy People 2000 goals: 1. Increase prop. Of people whose high BP is under control 2. Reduce mean-serum cholesterol levels 3. Reduce dietary fat intake & average unsaturated fat intake 4. Reduce prevalence rates of obese/oveweight adults
Slide 11-

5. Increase proportion of children & adults engaging in regular, daily physical activity at least 30 min/day 6. Reduce cigarette smoking among people age 20 and older http://www.health.gov/healthypeople
Slide 12-

CANCER 2nd leading cause of death in U.S. Incidence increases with age--Why? Most forms of cancer have a long latent period; initiating factors start during youth increasing age and accompanying physiological changes make one more susceptible to actions of carcinogens
Slide 13-

CA, cont’d …onset and management of many cancers do not vary greatly in the old and young. Prevention is still the order of the day regarding cancer.” p. 113. This includes:
Slide 14-

1. Avoiding unnecessary exposure to ionizing & ultraviolet radiation 2. Implementing hygienic measures in occupations involving exposure to CA-producing chemicals & dusts 3. Avoiding exposure to tobacco & cigarette smoke 4. Have periodic preventive medical exams.
Slide 15-

CEREBROVASCULAR DISEASE Results from: changes in blood vessels that serve the brain tissue cerebral infarction cerebral hemorrhage
Slide 16-

When a portion of the brain is completely denied blood, a cerebrovascular accident (CVA), or stroke results Severity is determined by location and total amount of brain tissue involved
Slide 17-

After diseases of the heart, malignant neoplasms, & accidents, cerebrovascular disease is the fourth-leading cause of death in the U.S.
Slide 18-

Cerbral Thrombosis Main cause of stroke in o.a.’s Occurs when a formed clot becomes lodges in an already narrowed artery.
Slide 19-

Stroke in evolution: May develop over hours or even days Symptoms can appear within minutes or hours after onset
Slide 20-

Transient ischemic attacks (TIA’S)--”mini-strokes” Warning signs of an impending stroke Transitory symptoms: sudden motor weakness speech dysfunction dizziness sudden changes in vision (especially in one eye) sudden falls
Slide 21-

Cerbral Embolism: Another cause of strokes Thrombus forms elsewhere in the body and travels to obstruct a vessel supplying the brain The onset of the stroke and its damage is immediate
Slide 22-

Damage from Strokes One-sided weakness or paralysis Sensory disturbances Aphasia (speech disorders) Mental symptoms Rehab should begin immediately
Slide 23-

APHASIA Impaired ability to comprehend or express verbal language Receptive aphasia: difficulty in processing external stimuli; may not understand other’s speech or what is read familiar objects may become unrecognizable
Slide 24-

Expressive aphasia A person understands what is said but cannot form the words or gestures to respond to stimuli May be incorrectly associated with mental deterioration
