sex, ApoE ε4 status, vascular risk factors) 6, 13. Mixed findings were reported for other risk factors (e.g. Higher age and post-stroke depression in individuals were associated with a cognitive decline 11, 12. A significant decline in global cognition was demonstrated a few years after stroke (from 3 to 6 years) 7, 8, whereas significant improvements in cognition were found within 6-months post-stroke 9, 10. Multiple evolving trends, such as improvement, worsening, or remaining stable, are shown to depend on the use of cognitive instruments, as well as the length of time until follow-up, whether short-term or long-term 6. Longitudinal changes in cognitive function after stroke were largely diverse. The ability to early recognize individuals with potential cognitive decline after stroke would make it possible to appropriately assess their actual needs and additional supports, while tailoring interventions towards these individuals, thus improving their quality of life. In addition to motor impairments, cognition decline is one of the key determinants of deterioration in performance of daily activities after stroke 5. Similar content being viewed by othersĬognitive impairment is a highly prevalent long-term stroke consequence, with approximately 80% of patients reporting mild cognitive impairments post-stroke 1, 2, 3, 4. These findings may help to increase focus on long-term rehabilitation plans for those patients, and more accurately assess their needs and difficulties experienced in daily living. Patients with the poorest cognitive function did not improve at one-year poststroke and were prone to severe memory problems. The impact on memory differs between cognitive functioning groups, whereas the impact on activities of daily living was not different. After age, sex and education matching to the normative MoCA from the Swedish population, 52 patients (55%) were found to be cognitively impaired at baseline, and few patients had recovered at 12 months. For the high and medium groups, cognitive function improved at 12 months, but this did not occur in the low group. Three cognitive functioning groups were identified by the trajectory models: high, medium and low. Data from 94 patients were included in the analysis. Individuals who shared similar trajectories were classified by applying the group-based trajectory models. The Montreal Cognitive Assessment (MoCA) was used to screen cognitive function at 36–48 h, 3-months, and 12-months post-stroke. The study aimed to determine longitudinal trajectories of cognitive function during the first year after stroke.
