Post-stroke Cognitive Impairment (CogStroke)
December 7, 2022 updated by: Roza Umarova
Prediction of Post-stroke Cognitive Decline and Dementia: Impact of Cognitive Reserve and Post-stroke Life Style
Present study aims to track the post-stroke cognitive trajectories and to investigate its inter-individual variability.

Detailed Description
The study aim is to establish a model capturing patients' inter-individual variability in susceptibility to stroke damage to predict stroke-induced cognitive trajectories.
This is a prospective longitudinal observational national monocentric study for 6 years (recruitment during the first 3 years).
The investigators perform comprehensive neuropsychological testing in i) acute stroke phase (0-10 days post-stroke), ii) sub-acute stroke phase (3 months post-stroke), and iii) chronic stroke phase (12 months and 3 years post-stroke).
At each time point, cognitive performances as well as clinical and functional status will be assessed.
Furthermore, the investigators will assess the proxies of cognitive reserve and the level of post-stroke physical activity.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of participants with delayed cognitive deterioration (DCD)
Time Frame: at 3 months, at 12 months and at 36 months post-stroke
|
The investigators will assess number of participants with deterioration of the cognitive performance in ≥2 cognitive domains on ≥ 1 Standard Deviation (1 SD).
|
at 3 months, at 12 months and at 36 months post-stroke
|
Number of participants with delayed functional deterioration
Time Frame: at 3 months, at 12 months and at 36 months post-stroke
|
The investigators will assess number of participants with deterioration of functional disability will be defined as decrease in disability level to one point assessed via modified Rankin Scale (mRS, 0-6, whereas 0=no functional disability).
|
at 3 months, at 12 months and at 36 months post-stroke

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of participants with post-stroke cognitive impairment
Time Frame: 10 days post-stroke, 3 months, 12 months and at 36 months post-stroke
|
The investigators will assess number of participants with post-stroke cognitive impairment that is defined as at least moderate deficit (performance below -1.5 SD) in ≥ 2 cognitive domains.
The cognitive performance across all basic cognitive domains is assessed using a standardized neuropsychological test battery with available normative data.
The test battery includes tests from Consortium to Establish a Registry for Alzheimer's Disease (CERAD), Trail Making Test A + B, verbal fluency, alertness test, digit span (forward and backward), Bells test, and Montreal Cognitive Assessment.
