Longitudinal assessments of cognition before PSD onset and at follow-up are scarce, leaving the association between PSD and subsequent global and domain-specific PSCI unclear. Digital assessments using task-derived kinematic parameters may provide complementary insights into cognitive vulnerability and PSD risk. Methods: In this prospective longitudinal study, patients with acute stroke underwent multidomain tablet-based neuropsychological assessment within the acute phase, before PSD onset, and at 90 days post-stroke.
