Part B (Q7): Describe the psychological and physical problems of older persons.

Ageing is a multi-dimensional process that brings about a cascade of interrelated physical and psychological challenges.

Physical Problems

1. Sensory Decline: The most immediate changes are often sensory. Presbyopia (farsightedness) and cataracts impair vision, leading to falls. Presbycusis (hearing loss) is incredibly common and directly contributes to social isolation because the elderly person can no longer participate in conversations.
2. Musculoskeletal Deterioration: Loss of muscle mass (sarcopenia) and bone density (osteoporosis) makes the elderly frail. Arthritis causes chronic, debilitating pain and drastically reduces mobility, making them dependent on others for basic tasks like bathing or dressing (Activities of Daily Living - ADLs).
3. Cardiovascular & Respiratory Issues: The heart muscle weakens, and blood vessels lose elasticity, leading to hypertension and a high risk of stroke or heart attacks. Lung capacity diminishes, causing shortness of breath and high susceptibility to infections like pneumonia.
4. Neurological Changes: Slower reflexes make them prone to accidents. More severely, neurodegenerative diseases like Parkinson’s (causing tremors and rigidity) and Alzheimer's disease destroy their physical independence.
5. Chronic Co-morbidities: Unlike younger people who get acute illnesses and recover, the elderly often suffer from multiple chronic conditions simultaneously (e.g., a person managing diabetes, arthritis, and hypertension all at once), leading to "polypharmacy" (taking many drugs, which risks adverse interactions).

Psychological Problems

The physical decline often acts as a trigger for psychological distress.

1. Depression and Grief: The elderly experience a "pile-up" of losses—the death of a spouse, the loss of lifelong friends, and the loss of their own physical abilities. This unrelenting grief, combined with the loss of professional identity post-retirement, frequently leads to clinical depression, which is often misdiagnosed as mere "grumpiness."
2. Anxiety and Fear: A profound fear of losing independence is common. They experience intense anxiety about becoming a physical or financial burden on their children. Health anxiety (hypochondriasis) is also prevalent, where minor pains are catastrophized into fatal illnesses.
3. Cognitive Impairment: Ranging from normal, mild age-related forgetfulness to severe dementias like Alzheimer's. The awareness of losing one's memory is initially terrifying for the individual, leading to paranoia and severe behavioral changes (aggression or wandering).
4. Loneliness and Social Isolation: With decreased mobility, hearing loss, and the death of peers, the social world of an older person shrinks drastically. In modern nuclear families, they may spend days without meaningful human interaction, leading to a profound sense of isolation and feeling "invisible" to society.
