Cognition and brain scans after a mini-stroke (TIA)
Official title: Cognitive Profile and Correlates in Neuroimaging After a Transient Ischemic Accident
Run by University Hospital, Caen · NCT04989608 · Data updated 2026-11-12
This project will test whether changes on brain scans relate to thinking and memory problems in people over 60 who recently had a transient ischemic attack (TIA) compared with similar older adults with vascular risk factors.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults 60 years or older who recently had a TIA without diffusion-restricted injury on MRI and can undergo MRI and give informed consent, or age-matched controls with one or more cerebrovascular risk factors enrolled in Medit-AGEING.
✕Probably not a fit
Patients with contraindications to MRI, prior major neurological disease (such as stroke, dementia, brain tumor), or those unable to consent or under legal/administrative detention are unlikely to be eligible or benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
The study enrolls people aged 60 and over who had a focal neurological deficit lasting less than 24 hours with no ischemic lesion on diffusion MRI within one week, alongside age-matched controls from the Medit-AGEING cohort who have vascular risk factors. Participants undergo standardized neuroimaging and cognitive testing to look for subtle brain changes that might explain cognitive difficulties after TIA. Individuals with MRI contraindications or major neurological comorbidities are excluded. Imaging markers will be correlated with cognitive performance to explore possible mechanisms for post-TIA cognitive impairment at Caen University Hospital.
Why it matters
Potential benefit: If successful, the study could clarify why some people develop lasting thinking problems after a TIA and identify imaging markers to guide follow-up or future interventions.
How similar studies have gone: Previous work has reported cognitive changes after TIA and some subtle imaging abnormalities, but linking specific imaging toxicity signals to cognition in diffusion-negative TIA remains relatively novel.
