False
27
What is the role of the Citizen’s Advice Bureau?
Offers legal and financial advice.
28
What is the impact of poor communication on older patients?
Can lead to misdiagnosis, non-adherence to treatment, and patient frustration.
29
What are some psychological theories of ageing?
* Maslow's Hierarchy of Needs * Jung's process of self-reflection * Erikson's integrity vs. despair
30
What are the challenges in geriatric medicine?
* Multiple diagnoses * Non-specific symptoms * Increased prevalence of mental issues * Polypharmacy
31
What is the Telomere Shortening theory of ageing?
Telomeres shorten with each cell division, eventually leading to cellular senescence and apoptosis
32
What does the Free Radical theory propose?
Ageing results from cumulative oxidative damage by free radicals to DNA, proteins, and membranes.
33
Describe the Mitochondrial theory of ageing.
Ageing is driven by mitochondrial DNA mutations that impair energy production.
34
What is the idea behind Genetic Programming in ageing?
Certain genes regulate ageing by controlling cell repair and programmed cell death.
35
What changes occur in the cardiovascular system with age?
Decreased vessel elasticity, increased collagen and calcium, reduced diastolic function, valvular sclerosis, and arrhythmia risk.
36
What is sarcopenia and what causes it?
Age-related muscle loss due to disuse, hormonal decline, and neuronal degeneration.
37
Define immunosenescence.
Age-related immune decline with fewer functional T-cells, lower antibody response, and higher infection risk.
38
Name 3 key changes in the renal system with age.
Reduced GFR, nephron loss, increased renal artery resistance.
39
What causes presbyopia and presbyacusis?
Lens stiffening (presbyopia) and cochlear hair cell degeneration (presbyacusis).
40
What is geriatric medicine?
A subspecialty of internal medicine focusing on the complex health needs of older adults.
41
What challenges are common in geriatric medicine?
Polypharmacy, multiple comorbidities, cognitive impairment, nonspecific symptoms, social issues.
42
What is the Hayflick Limit?
Human cells divide ~40–60 times before senescence, due to telomere shortening.
43
What is the Disposable Soma theory?
Energy is prioritised for reproduction over somatic cell repair, leading to gradual ageing.
44
Define ageism.
Discrimination or stereotyping based on age, often toward older adults.
45
How does ageism affect healthcare for older patients?
Leads to delayed diagnoses, undertreatment, mental health decline, and poor communication.
46
What is the impact of hearing and visual loss in older adults?
Reduces communication effectiveness, increases risk of isolation and misunderstanding in care.
47
What are the communication challenges with dysphasia?
Difficulty expressing or understanding speech, especially after stroke or in dementia.
48

Decreased T-cell response, lower antibody production, and poor vaccine response.
59
Why is fever a less reliable sign of infection in older people?
20–30% of elderly patients have a diminished febrile response due to immune decline.
60
What vascular changes occur with age?
Reduced elastin, increased collagen/calcium, leading to stiff vessels and hypertension.
61
How does the ageing heart affect diastolic function?
Impaired relaxation reduces ventricular filling and perfusion.
62
What structural heart changes increase arrhythmia risk in older adults?
Fibrosis and fatty deposits in the conduction system.
63
What happens to the baroreceptor response with age?
It declines, increasing the risk of postural hypotension.
64
What gait changes increase fall risk in older adults?
Reduced gait speed and stride length, increased postural sway, and slower reflexes.
65
What happens to GFR with age and why?
GFR decreases due to nephron loss, glomerulosclerosis, and reduced blood flow.
66
What structural renal changes are common in ageing?
Cortical mass loss, thickened basement membrane, arteriole sclerosis.
67
Why do older adults experience swallowing difficulties?
Reduced oesophageal motility and saliva production.
68
What condition increases gastric inflammation in the elderly?
Atrophic gastritis, often linked to H. pylori and prostaglandin decline.
69
What causes constipation in older adults?
Reduced colonic peristalsis and weakened connective tissue.
70
What lung function values decline with age?
FEV1 and vital capacity decrease; residual volume increases.
71
Why does respiratory efficiency decline in older adults?
Loss of elastic recoil, weaker muscles, increased chest wall compliance.
72
What causes presbyopia in older people?
Lens hardening and reduced flexibility, impairing close vision.
73
What causes age-related hearing loss (presbyacusis)?
Degeneration of cochlear hair cells and neurons, vascular changes, and noise damage
74
