Introduction to Geriatrics - Age Old Wisdom
- Geriatrics: Branch of medicine for health, diseases, and care of older adults (India: ≥60 yrs).
- Ageing: Natural, progressive, irreversible process; NOT synonymous with disease.
- Demographic Shift (India): Rapid ↑ in elderly population.
⭐ India's elderly population (≥60 years) is projected to reach 319 million by 2050, constituting ~20% of total population.
- Key Physiological Changes:
- ↓ Homeostatic reserve (reduced ability to cope with stressors).
- Immunosenescence (↓ immune function).
- Sensory decline (e.g., presbycusis, presbyopia).
- Musculoskeletal: Sarcopenia (↓ muscle mass/strength), Osteoporosis (↓ bone density).
Common Geriatric Syndromes - The Falling I's
📌 Mnemonic: Key areas of decline, the 'I's:
- Instability (Falls):
- Major cause of injury, disability in >65 yrs.
- Risks: polypharmacy, weakness, poor vision/gait.
- Timed Up and Go (TUG) test: >12s indicates ↑fall risk.
- Immobility:
- Leads to: pressure ulcers, DVT, deconditioning.
- Address pain, encourage safe mobility.
- Incontinence (Urinary):
- Not normal aging. Types: stress, urge, overflow, functional.
- Requires careful assessment.
- Intellectual Impairment:
- Delirium (acute), Dementia (progressive).
- Screen: Mini-Cog, MMSE.
- Iatrogenesis:
- Harm from medical care (e.g., polypharmacy).
- Review meds using BEERS criteria.
- Impaired Senses (Vision/Hearing):
- Impact safety, communication, QoL.
- Screen regularly.
⭐ Delirium in an elderly patient is often precipitated by a simple urinary tract infection (UTI) and can be the sole presenting symptom.
NCDs in the Elderly - Chronic Challenges
- Prevalent NCDs: Hypertension (HTN), Diabetes Mellitus (DM), Cardiovascular diseases (CVD - e.g., CAD, Stroke), COPD, Osteoarthritis, Osteoporosis, common Cancers (prostate, breast, colorectal), Dementia (esp. Alzheimer's), Depression.
- Key Challenges:
- Atypical presentations: e.g., confusion with UTI/pneumonia, silent MIs.
- Polypharmacy: ↑ risk of drug interactions & adverse drug reactions (ADRs).
- Multiple comorbidities: complicating diagnosis and management.
- Functional decline & frailty: impacting activities of daily living (ADLs).
- "Geriatric Giants": Immobility, Instability (falls), Incontinence, Impaired Intellect/Memory.
- Management Focus:
- Comprehensive Geriatric Assessment (CGA) for holistic care.
- Individualized treatment goals: prioritizing Quality of Life (QoL) & function.
- Medication review (e.g., Beers criteria, STOPP/START tools) to minimize polypharmacy.
⭐ Atypical presentation of myocardial infarction in elderly includes syncope, acute confusion, or stroke, often without chest pain (silent MI).
Geriatric Assessment & Prevention - Golden Years Guard
- Comprehensive Geriatric Assessment (CGA): Multidimensional, interdisciplinary evaluation for frail elderly. Assesses:
- Medical: Comorbidities, polypharmacy (≥5 drugs).
- Functional: ADL (Katz), IADL (Lawton).
- Cognitive: MMSE, MoCA.
- Psychosocial: GDS (depression), social support.
- Nutritional: MNA.
- Mobility: Timed Up and Go (TUG) test; >12 sec indicates ↑fall risk.
- Prevention Strategies:
- Primary: Immunizations (influenza, pneumococcal, zoster), fall prevention programs, regular exercise.
- Secondary: Early detection via screening (BP, diabetes, common cancers, osteoporosis with DEXA).
- Tertiary: Rehabilitation, managing chronic conditions, palliative care.
- Key Initiative: National Programme for Health Care of the Elderly (NPHCE) in India.

⭐ Polypharmacy (≥5 drugs) is a major risk factor for adverse drug events and hospitalizations in the elderly.
High‑Yield Points - ⚡ Biggest Takeaways
- Geriatric Giants (5 Is): Immobility, Instability (falls), Incontinence, Intellectual Impairment (dementia/delirium), Iatrogenesis.
- Prevalent NCDs: Hypertension, Diabetes Mellitus, Osteoarthritis, COPD, Cancers, and Alzheimer's Disease.
- Assess functional status using ADL (Activities of Daily Living) & IADL (Instrumental ADL).
- Polypharmacy significantly ↑ risk of adverse drug events and drug interactions.
- Prioritize fall prevention strategies, adequate nutrition (Vit D, B12, Calcium), and key vaccinations (influenza, pneumococcal).
- Screen for depression and cognitive decline regularly; elder abuse awareness is crucial.
