Treatable illnesses causing death in Alzheimer's
Key points
- Pneumonia is a common cause of death in Alzheimer's, often from aspiration due to swallowing difficulties.
- Dehydration and malnutrition are preventable with daily fluid and food tracking.
- Falls are a major risk; use a fall prevention kit and remove hazards.
- Infections can be treated if caught early—watch for increased confusion or fever.
- Work with clinicians for swallowing evaluations and diet modifications.
- Hospice care is appropriate in late stages and focuses on comfort and quality of life.
General caregiving information, not medical advice. Check medications and major care changes with your clinician.
Step-by-step
Watch for swallowing problems (coughing during meals, wet-sounding voice after eating, food pocketing in cheek) and ask about a swallowing evaluation; thickening liquids or pureeing foods can reduce aspiration risk.
Keep a daily fluid log on a fridge chart, offering small sips every hour, because dehydration can trigger urinary tract infections and worsen confusion.
Reduce fall risks by removing loose rugs, improving lighting, adding non-slip mats and grab bars; encourage short supported walks to preserve strength and help prevent pressure ulcers.
Learn early infection signs (new confusion, lethargy, fever, breathing changes) and call the clinician promptly.
Brush teeth or dentures twice daily with a soft brush; oral bacteria can travel to the lungs and cause pneumonia.
Use a pill organizer, keep an updated medication list, and watch for side effects like dizziness or increased confusion.
Build a calm daily routine and use one-step instructions like 'Sit down now'—multi-step requests can overwhelm and trigger agitation.
What not to do
Don't force-feed or offer straws to someone with swallowing difficulty—small spoonfuls of soft or pureed food are safer.
Don't leave your loved one alone near stairs; a bedside commode can be safer for nighttime needs. Always ask the doctor before using a bed rail due to entrapment risks.
Don't skip regular medical check-ups even if things seem stable—untreated conditions like high blood pressure can accelerate decline.
Don't argue or try to reason with someone in distress; redirect gently instead.
Practical tools
Swallowing Safety Checklist
Post near the dining area: (1) Is the person sitting upright at 90 degrees? (2) Are foods cut into small pieces? (3) Is the person alert? (4) Any signs of coughing or choking? Review before each meal.
Hydration Tracker Chart
Create an 8-row chart for each day on the fridge. Mark off each cup of fluid (water, juice, soup). Aim for at least 6 cups daily.
Fall & Mobility Safety Kit
Assemble: non-slip socks, bed alarm, grab bars, hallway nightlight, call button by the bed, sturdy chair with armrests, and a gait belt. Test alarm weekly and stop if it causes distress.
Infection Watch Card
Laminated card listing signs: fever (over 100.4°F), increased confusion, lethargy, change in urine color or odor, coughing, rapid breathing. Keep on fridge or in wallet; call clinician if any sign appears.
Discuss with your clinician
Ask about a formal swallowing evaluation by a speech-language pathologist if you notice any coughing during meals.
Discuss the use of thickened liquids or pureed diets to reduce aspiration risk. Do not start these without professional guidance.
Inquire about a referral to a dietitian for a personalized nutrition plan if weight loss is a concern.
Ask about the appropriate use of antibiotics for infections, especially if your loved one has advanced directives limiting aggressive treatment.
Discuss the role of hospice care when the person becomes bedbound, non-verbal, and has difficulty swallowing. Hospice can provide comfort-focused care and support for the family.
Ask your doctor: 'Is a bed rail safe for my loved one, or are there better alternatives like a floor mat or low bed to prevent falls without entrapment risk?'
