FAQ: New Risk Assessment Tool for Predicting Dementia After Stroke
TL;DR
This new risk calculator gives researchers an edge by identifying high-risk stroke patients for clinical trials, accelerating dementia prevention research.
The tool analyzes factors like age, disability, and diabetes to stratify stroke survivors into five risk levels for dementia within ten years.
By predicting dementia risk early, this tool helps develop better interventions, improving long-term quality of life for stroke survivors and their families.
A Canadian study of 50,000 stroke patients created a bedside tool that can predict dementia risk with 50% accuracy for high-risk individuals.

The tool predicts the likelihood of adults developing dementia within ten years after a stroke, stratifying people into five different levels of dementia risk based on underlying health, stroke characteristics, and risk factors.
Knowing the risk of developing dementia after a stroke can help researchers design better clinical trials and interventions, and guide recruitment of eligible patients for efforts to lower dementia risk.
Higher risk factors include being older, having any disability before the stroke, higher disability after the stroke, having an intracerebral hemorrhage (compared to ischemic stroke), having diabetes, experiencing cognitive symptoms during hospitalization, or suffering from depression.
Researchers examined health records for nearly 50,000 adults hospitalized with stroke from the Ontario Stroke Registry to create and validate the risk model.
The tool was developed by lead researcher Raed A. Joundi, M.D., D.Phil., M.Sc., and colleagues in Canada, using data from the Ontario Stroke Registry and statistical analysis done at ICES Central in Toronto.
The preliminary study will be presented at the American Stroke Association's International Stroke Conference 2026 in New Orleans, February 4-6, 2026.
The tool may help enroll high-risk patients who have had transient ischemic attack (TIA), ischemic stroke, or intracerebral hemorrhage in clinical trials focused on reducing long-term dementia risk.
This study is a research abstract presented at a scientific meeting and is not yet peer-reviewed; findings are considered preliminary until published as a full manuscript in a peer-reviewed scientific journal.
