NEW research from the Centre for Healthy Brain Ageing reveals that older adults who suffer a stroke for the first time experience immediate and long-term cognitive decline.
Published in JAMA Network Open, the study highlights stroke as a leading cause of disability and dementia worldwide.
The research, led by biostatistician Jess Lo, analysed data from 14 global studies, tracking 20,860 participants over time.
It found that cognitive decline accelerates after a stroke, impacting areas such as memory, language, and decision-making.
Vascular dementia, the second most common form of dementia, was a key focus.
Lo said, "we wanted to understand how stroke affects cognitive abilities both short and long term".
The study also revealed that individuals with risk factors including diabetes, hypertension, and smoking experienced faster cognitive decline even before stroke onset.
