Geriatrics

The branch of medicine focused on the health and care of older adults โ€” addressing aging, chronic disease management, cognitive decline, falls, and end-of-life care.

Key Clinical Formulas

Cockcroft-Gault Creatinine Clearance:
CrCl = [(140 โˆ’ age) ร— weight(kg)] / (72 ร— SCr) ร— 0.85 (if female)
Adjusts drug dosing for renal impairment in elderly
Beers Criteria:
Lists potentially inappropriate medications for adults โ‰ฅ65 years. Examples: benzodiazepines, anticholinergics, NSAIDs, Z-drugs, digoxin >0.125 mg.
Core Concepts
1. Frailty Syndrome
Fried phenotype: unintentional weight loss, exhaustion, low physical activity, slowness, weakness. โ‰ฅ3 criteria = frail; 1-2 = pre-frail. Frail adults have increased risk of falls, hospitalization, disability, and death.
2. Delirium vs. Dementia
Delirium: acute onset (hours-days), fluctuating course, inattention, altered consciousness. Reversible. Dementia: chronic progressive decline (months-years), memory loss dominant. Depression: pseudodementia โ€” slow but preserved attention. All require different management.
4. Dementia and Alzheimer's Disease
Alzheimer's: 60-80% of dementias. Neurofibrillary tangles (tau) + amyloid plaques. Vascular: 15-20%. Lewy body, frontotemporal, mixed. Diagnosis: cognitive testing (MMSE/MoCA), neuroimaging, labs. Treatment: cholinesterase inhibitors, memantine, lifestyle.
Core Definitions
Orthostatic Hypotension: Drop in systolic BP โ‰ฅ20 mmHg or diastolic โ‰ฅ10 mmHg within 3 minutes of standing. Common in elderly: autonomic dysfunction, dehydration, medications. Causes falls, syncope, and cognitive impairment.
Palliative Care: Specialized medical care for people with serious illness. Focuses on quality of life, symptom management, and goals-of-care conversations. Not synonymous with hospice โ€” can be provided alongside curative treatment at any stage.
