Week 9 Chronic Illness New D2L

Chronic Disease and Aging

Chronic illness refers to conditions that persist for a year or more and necessitate ongoing medical attention, impacting daily living activities or both. The global health concern escalates due to the rising prevalence and associated costs, particularly in elderly populations. In Canada, up to 60% of older adults living in the community suffer from two or more chronic conditions. Nonfatal conditions include osteoarthritis, whereas more severe illnesses can lead to significant morbidity or mortality such as organ failures, strokes, or dementia. Notably, frailty is characterized as a critical, chronic state of deteriorated health where the body has diminished reserves, making any disturbance potentially severe.

Chronic vs. Acute Illness

Chronic illnesses continue indefinitely, requiring management rather than seeking a cure, obligating patients to adapt to their conditions. In contrast, acute illnesses manifest suddenly, often without warning, requiring immediate medical intervention. Examples include acute myocardial infarction and strokes, which necessitate timely responses.
