Study on the trajectory and influencing factors of post-stroke cognitive development: based on a group-based trajectory model

Background Post-stroke cognitive impairment (PSCI) is one of the major complications of stroke and exhibits a dynamic progression. This study uses the Group-Based Trajectory Model (GBTM) to fit cognitive development trajectories in stroke patients and analyze the influencing factors and trends of PSCI across trajectory groups. It aims to facilitate early identification and intervention for high-risk PSCI patients, providing a theoretical basis for optimizing intervention strategies.
