A prospective cohort study on longitudinal trajectories of cognitive function after stroke

Abstract The study aimed to determine longitudinal trajectories of cognitive function during the first year after stroke. The Montreal Cognitive Assessment (MoCA) was used to screen cognitive function at 36–48 h, 3-months, and 12-months post-stroke. Individuals who shared similar trajectories were c...

The Montreal Cognitive Assessment (MoCA) was used to screen cognitive function at 36–48 h, 3-months, and 12-months post-stroke.

For the high and medium groups, cognitive function improved at 12 months, but this did not occur in the low group.

Patients with the poorest cognitive function did not improve at one-year poststroke and were prone to severe memory problems.
