Patients with ischemic stroke are at risk for developing cognitive impairment. Hippocampal size was calculated from 102 first-ever stroke patients using FreeSurfer. At baseline, patients with smaller hippocampi (below median) did not differ in their parameters (cognitive scores, NIHSS and years of education) from those with larger hippocampi. Six months after the event, improvements were observed in cognitive scores for both groups. However, 12 months post-stroke, patients with larger hippocampi presented better cognitive function compared to the other group. These preliminary results may suggest that stroke patients presenting with smaller hippocampi are prone to develop cognitive decline 12 months later.
