The query: title or abstract mentions "Alzheimer" or "dementia" AND "survival", "life expectancy", "time to death", "years after/from diagnosis", "all-cause mortality", "cause of death", "place of death", "end of life", "palliative" or "hospice", matched case-insensitively against each record's title and abstract (its summary field) in alzhub's library of 29,380 study records, as of 2026-11-08. Every count on this page comes from that match. The matched list as JSON.

Survival studies follow people from diagnosis (or from symptom onset) and report the median time to death and the factors linked to shorter or longer survival: age at diagnosis, sex, how advanced the disease was when diagnosed, other illnesses, and dementia type. Because many people are diagnosed years after symptoms began, survival from diagnosis understates survival from onset.

Alzhub's library reports what these papers found; it does not predict any person's course. The figures quoted below are group medians and ranges from the studies named.

This page describes what published research in alzhub's library reports. It is not medical advice and does not apply to any one person: a doctor who knows the person's history is the only one who can say what a result or a treatment means for them.

Questions

How long do people live after an Alzheimer's diagnosis?
It varies widely with age at diagnosis, stage at diagnosis, other illnesses and dementia type, and the studies below report group medians, not individual predictions. Someone diagnosed early and young typically lives longer than the median; someone diagnosed late and old, shorter.
What usually causes death in Alzheimer's?
In the late stage the disease affects swallowing, movement and immunity, so pneumonia and other infections are the most commonly recorded causes. The papers in the set that studied cause of death give the breakdown they found.
How many studies on life expectancy after diagnosis does alzhub hold?
1,699 of the 29,380 study records in alzhub's library match the query "title or abstract mentions "Alzheimer" or "dementia" AND "survival", "life expectancy", "time to death", "years after/from diagnosis", "all-cause mortality", "cause of death", "place of death", "end of life", "palliative" or "hospice""; 365 of them name it in the title. Counted from the records when this page was built.
What kinds of study are they?
67 systematic review or meta-analysis, 32 randomised controlled trials, 7 other clinical trials, 245 cohort or longitudinal studys, 8 case-control studys, 79 cross-sectional studys; 1,244 record no design.
What is the most recent study in the set?
"Inflammatory biomarker candidates in dementia with Lewy bodies: diagnostic classification, clinical associations, and survival" (Research Square, 2026), the newest by publication date among the matched records.
Which journals publish most on it?
Journal of the American Geriatrics Society (74); Neurology (55); Palliative medicine (45), counted across the matched records.
