Session 2 Flashcards
- Frailty is?
- loss of biological reserves and vulnerability to adverse outcomes
a common clinical syndrome in older adults that carries an increased risk for poor health outcomes e.g. falls, incident disability, hospitalization, & mortality .
How do you measure frailty

What is the graph showing

Age, electronic frailty index score and mortality
- Sarcopenia:
- Sarcopenia is a component of?
- degenerative loss of skeletal muscle mass (0.5–1% loss per year after the age of 50), quality, and strength associated with aging
- frailty syndrome - elevated risk of declines in health and function among older adults
cachexia/wasting syndrome - loss of weight, muscle atrophy, fatigue, weakness, & significant loss of appetite in someone who is not actively trying to lose weight.
Cachexia is seen in people with?
cancer, AIDS, coeliac disease, chronic obstructive pulmonary disease, multiple sclerosis, rheumatoid arthritis, congestive heart failure, tuberculosis, familial amyloid polyneuropathy, mercury poisoning (acrodynia), Crohn’s disease, untreated/severe type 1 diabetes mellitus, anorexia nervosa, and hormonal deficiency.
- Osteopaenia:
- bone mineral density is lower than norma
Sarcopenia refers to loss of muscle mass and low muscle function (strength or performance) that occurs as a result of old age. It is characterized first by a decrease in muscle mass, which causes weakness and frailty. However, this loss of muscle mass may be caused by different cellular mechanisms than those that cause muscle atrophy. For example, during sarcopenia, there is a ?
replacement of muscle fibres with fat and an increase in fibrosis
What are the four key features in geriatric patients?
- Non-specific presentations
- Homeostatic failure
- Multiple pathology & polypharmacy
- Differential challenge
Moderate to severe frailty strongly associated with non-specific presentations -> give e.g. of non-specific presentations
- Falls, immobility, off legs, collapse ? cause
- Confusion (delirium and/or dementia)
- “Acopia” or “social admission” (phrases never to use!)
- Other diffuse or multiple statements related to disability
The natural ageing process means that older people have an increased risk of having a fall. In the UK, falls are the most common cause of injury related deaths in people over the age of 75.
Older people are more likely to have a fall because they may have:
- balance problems and muscle weakness
- poor vision
- a long-term health condition, such as heart disease, dementia or low blood pressure (hypotension), which can lead to dizzinessand a brief loss of consciousness
Difference between dementia and delirium i.e. causes, onset,
Osteoporosis

Acopia
patient’s inability to cope with activities of daily living
Delirium
There are several medical definitions of delirium (including those in the DSM-IV and ICD-10). However, all include some core features.
The core features are:
Disturbance of consciousness (that is, reduced clarity of awareness of the environment, with reduced ability to focus, sustain, or shift attention)
Change in cognition (e.g., problem-solving impairment or memory impairment) or a perceptual disturbance (hallucination)
Onset of hours to days, and tendency to fluctuate.
Behaviour may be either overactive or underactive, and sleep is often disturbed, with loss of the normal circadian rhythm.
Thinking is slow and muddled but the content is often complex.
The most common causes of sudden confusion are:
a lack of oxygen in the blood (hypoxia) – the cause could be anything from a severe asthma attack to a problem with the lungs or heart
an infection anywhere in the body, especially in elderly people
a stroke or TIA (“mini stroke”)
a low blood sugar level (hypoglycaemia)
diabetic ketoacidosis, a serious complication of diabetes caused by a lack of insulin in the body
certain medications, including digoxin, diuretics, steroids, and opiates
alcohol poisoning or alcohol withdrawal
drug misuse
what do they mean by Homeostatic failure
- Balance, temperature, blood pressure, sodium, etc
- Biological systems usually robust: multiple feedback loops
- Failure either due to overwhelming single disease, or lesser disease with multiple co- morbidity
How and why does balance change with age?
How and why does temperature change with age?
How and why does bp change with age
What does it mean by pathology?
- Cognitive impairment
- Iatrogenesis
- Deafness and blindness
- Axial osteoarthritis
- Vascular (cerebral, cardiac, renal, peripheral)
- Diabetes
- Respiratory disease
- Depression
Iatrogenesis
any effect on a person, resulting from any activity of one or more persons acting as healthcare professionals or promoting products or services as beneficial to health, that does not support a goal of the person affected
Some iatrogenic effects are clearly defined and easily recognized, such as a complication following a surgical procedure (e.g., ? as a result of breast cancer surgery). Less obvious ones, such as complex drug interactions, may require significant investigation to identify.
lymphedema
While some have advocated using ‘iatrogenesis’ to refer to all ‘events caused by the health care delivery team’, whether ‘positive or negative’, consensus limits use of ‘iatrogenesis’ to adverse effects, possibly including, broadly, all adverse unforeseen outcomes resulting from medication or other medical treatment or intervention.
Cases of iatrogenesis include:
side effects of possible drug interactions
complications arising from a medical procedure or treatment
medical errors
negligence
use of contaminated instruments
anxiety or annoyance in the physician or treatment provider in relation to medical procedures or treatments
unnecessary medical treatment resulting from a physician’s decision
Osteoarthritis (OA) is a type of joint disease that results from breakdown of joint cartilage and underlying bone.[5] The most common symptoms are joint pain and stiffness.[1] Initially, symptoms may occur only following exercise, but over time may become constant.[1]Other symptoms may include joint swelling, decreased range of motion, and when the back is affected weakness or numbness of the arms and legs.[1] The most commonly involved joints are those near the ends of the fingers, at the base of the thumb, neck, lower back, knee, and hips.[1] Joints on one side of the body are often more affected than those on the other.[1] Usually the symptoms come on over years.[1]It can affect work and normal daily activities.[1] Unlike other types of arthritis, only the joints are typically affected.[1]
Vulnerable homeostatic systems need protection from challenge…..but…
- Living alone
- Poverty
- Poor housing
- Ageism
