Analysis of cognitive function trajectories and influencing factors in elderly patients with ischemic stroke: a prospective longitudinal study

Geriatric patients with ischemic stroke have a gradual decline in cognitive function over time. Cognitive change trajectories can be categorized into three latent groups: High Cognitive Function-Slow Decline Group, Low Cognitive Function-Intermediate Decline Group, and Low Cognitive Function-Rapid Decline Group. Healthcare practitioners can develop tailored intervention strategies based on individual patients' cognitive trajectories and influencing factors to reduce cognitive decline and improve quality of life.
