Frailty Flashcards
Why are there more old people
How many old people will there be by 2050
Increases in resources, better living conditions, improved screening programs, better outcomes following major health events such as stroke, surgery, heart attacks.
2 billion over 60’s by 2050
What is stochastic theory of ageing
Cumulative damage occurs to the body in a random manner leading to a decrease in health
What is the programmed theory of ageing
Predetermined failure of the body determined by changes in gene expression at various stages
How are the kidneys affected with age
Rapidly decreases, creatinine clearance decreases by 4 fold in men and 3 fold in woman
How does blood pressure change with age?
Systolic blood pressure increaes rapidly in those of an older age, average systolic is 140-150 in those over 80. Diastolic blood pressure decreases past 60, increasing the pule pressure in those over 60.
Why does blood pressure change with age?
Blood pressure is lowered in response in increasing blood pressure
Pressure sensitive receptor in the carotid detects these changes and sends messages to the brain.
Activates sympathetic system to increase cardiac output increasing blood pressure
How does cardiac output change with age?
Decreases
How does lung capacity change with age?
Residual volume increases,
expiatory volume decreases,
inspiratory reserve volume slightly decreases with age
How does ability to control temperature change?
Circadian rhythm decreases,
sweat gland output decreases,
blood flow to skin decreases,
cardiac output increases in response to heat,
blood flow is redistributed from the kidneys and splachnic centres.
Reduced peripheral vasoconstriction and metabolic heat production
What s frailty
Progressive dyshomeostasis. Susceptibility of an individual to become more likely to lose function in the face of given environmental factors. This results in frailty syndromes such as falls, delirium, immobility or incontinence.
What are the classic symptoms of hyperthyroidism?
Tremor
anxiety
weight loss
diarrhoea
What are the symptoms of hyperthyroidism in the elderly
Depression, cognitive impairment, muscle weakness, A fib, heart failure, angina
Whats worrying about elderly and drugs
They take the most of them however there is limited research to show how it effects them. e.g. bisoprolol not shown to have any change in adverse outcomes
How many elderly people do drugs?
98%,
36% take more than 5 medications
How do adverse drug reactions effect the elderly
Increased with the more medications you take. e.g. 4% adverse reactions with 5 drugs take
11-15 drugs 24% ADR
21 or more drugs 45% ADR
