In a study of over 3,000 ICU patients aged 50 and older, post-ICU stroke and depression were significantly associated with increased risk of developing dementia. Unlike typical Alzheimer’s disease risk factors, cardiovascular risks were not linked to post-ICU dementia. These findings highlight the need for future interventions targeting stroke and depression to reduce dementia incidence in ICU survivors.
