Geriatric Medicine
Geriatric medicine for MBBS: atypical presentation, comprehensive assessment, delirium and dementia, falls and osteoporosis, mapped to NMC codes IM24.1 to IM24.22.
This chapter covers the distinctive medicine of older adults, including atypical presentation, comprehensive geriatric assessment and the major geriatric syndromes of delirium, dementia, falls and osteoporosis. It emphasises the hazards of polypharmacy, sensory loss and the social and ethical dimensions of elderly care.
High-yield: Geriatric Medicine
- Older adults often present atypically, with a serious illness manifesting as confusion, falls or functional decline.
- Comprehensive geriatric assessment is a multidimensional evaluation of medical, functional, cognitive and social domains.
- Delirium is an acute confusional state with a fluctuating course and inattention, often triggered by infection or drugs.
- Delirium must be distinguished from dementia, which is chronic and progressive rather than acute and fluctuating.
- Dementia is a progressive decline in cognition, with Alzheimer disease the commonest type.
- Depression in older adults can mimic dementia and is an important reversible cause of cognitive complaints.
- Falls are multifactorial and a leading cause of injury, disability and loss of independence in older adults.
- Osteoporosis raises the risk of fragility fractures, especially of the hip and vertebrae.
- Polypharmacy increases the risk of adverse drug reactions and interactions in the elderly.
- Age-related changes in pharmacokinetics require cautious dosing, especially of renally cleared drugs.
- Sensory impairment from vision and hearing loss contributes to isolation and functional decline.
- Incontinence, immobility and pressure injuries are important geriatric syndromes to prevent.
- Elder abuse and social isolation require active screening and a supportive response.
- Rehabilitation and social support help maintain independence and quality of life.
- Advance care planning and ethical decision-making are central to the care of older adults.
Geriatric essentials
- **Atypical presentation:** Serious illness may present as confusion, falls or functional decline.
- **Delirium versus dementia:** Delirium is acute and fluctuating with inattention; dementia is chronic and progressive.
- **Geriatric syndromes:** Falls, osteoporosis, incontinence and sensory impairment need active management.
- **Prescribing:** Polypharmacy and altered pharmacokinetics demand cautious, reviewed drug use.

Frequently Asked Questions
How does delirium differ from dementia?
Delirium is an acute confusional state with a fluctuating course and prominent inattention, usually triggered by an acute illness or drug, whereas dementia is a chronic, progressive decline in cognition.
What is comprehensive geriatric assessment?
It is a multidimensional evaluation of an older adult's medical, functional, cognitive, psychological and social domains, used to guide a coordinated management plan.
Why is prescribing more hazardous in older adults?
Polypharmacy and age-related changes in drug handling increase the risk of adverse reactions and interactions, so drugs are used cautiously and reviewed regularly.
How does this chapter help for NEET-PG?
Atypical presentation, the delirium versus dementia distinction, geriatric syndromes and safe prescribing are common exam themes that map directly to questions.
