BACKGROUND AND PURPOSE: Decompressive hemicraniectomy (DH) improves survival and functional outcome in large middle cerebral artery (MCA) infarcts. However, long-term cognitive outcomes after DH remain underexplored. In a cohort of patients with large right-hemisphere MCA infarction undergoing DH, we assessed the rates of long-term cognitive impairment over 3-year follow-up.
METHODS: We prospectively evaluated consecutive patients included in the Lille Decompressive Surgery Database (May 2005-April 2022) undergoing DH according to existing guidelines for large hemisphere MCA infarction. We included patients with right-sided stroke and screened with the Mini-Mental State Examination (MMSE) in at least one of the prespecified follow-ups (3-month, 1-year, 3-year). Cognitive impairment was defined as an MMSE score < 24. We included only right-hemisphere strokes to avoid testing biases related to severe aphasia. We compared clinical and neuroimaging data in patients with and without cognitive impairment.
RESULTS: Three hundred four patients underwent DH during the study period. Among 3-month survivors, 95 had a right-hemisphere stroke and underwent at least one cognitive screening (median age = 51 years, 56.8% men). Forty-four patients (46.3%) exhibited cognitive impairment at least once during the 3-year follow-up. Baseline characteristics did not significantly differ between patients with and without cognitive impairment. Regarding long-term temporal trends, cognitive impairment was observed in 23 of 76 (30.3%), 25 of 80 (31.3%), and 19 of 66 (28.8%) patients at 3-month, 1-year, and 3-year follow-up, respectively, and it was associated with higher rates of functional disability (all p < 0.05).
CONCLUSIONS: The persistently high rates of cognitive impairment after DH highlight the importance of cognitive monitoring to improve the long-term management of survivors.
