Background
Previous literature has shown disparities between developing and developed regions in executive functioning, attention, and processing speed performance following stroke. Research on post‐stroke longitudinal outcomes in Latin America specifically is almost nonexistent.
Objectives
To assess spontaneous recovery among individuals with stroke in the absence of cognitive rehabilitation services in Colombia, South America during the first year post‐stroke by comparing their functioning to that of healthy controls across executive functioning, attention, and processing speed at 3, 6, and 12 months.
Design
Cohort.
Setting
Stroke rehabilitation center at the regional hospital.
Participants
A sample of 50 individuals with stroke and 50 matched healthy controls from Colombia were included in this study. Consistent with the healthcare resources in this region, participants did not receive any inpatient or outpatient cognitive rehabilitation.
Interventions
Not applicable.
Main Outcome Measures
Executive functioning, attention, and processing speed.
Results
Hierarchical linear models suggested improvements over time for both individuals with stroke and controls, but trajectories of neuropsychological performance were significantly lower for individuals with stroke. Only on one of nine outcomes was there a significant time*group interaction, suggesting greater gains for the stroke group than controls.
Conclusions
These data suggest extremely minor spontaneous recovery among individuals with stroke in Colombia relative to practice effects in controls, and that apparent improvements in executive functioning after stroke were likely just due to practice effects. These findings underscore the bleak outcomes in cognitive functioning after stroke that occur in regions without cognitive rehabilitation.
