Abstract

Objectives: Survivors of mild-grade aneurysmal subarachnoid hemorrhage (aSAH) often achieve favorable neurological recovery, yet many continue to experience cognitive difficulties and reduced health-related quality of life (HRQoL). The relative contribution of objectively measured cognition and subjective cognitive complaints to long-term HRQoL in this population remains insufficiently clarified.

Methods: This prospective cohort study assessed objective and subjective cognitive functioning one year after mild-grade aSAH (Hunt & Hess I-II) and examined their unique contributions to HRQoL. Forty endovascularly treated aSAH survivors and 80 neurologically healthy controls, matched for sex, age, and educational level, were assessed 12-14 months post-ictus using the Montreal Cognitive Assessment (MoCA), Cognitive Failures Questionnaire (CFQ), and SF-36.

Results: Compared with controls, patients demonstrated significantly lower MoCA scores, with cognitive impairment present in 42.5% of cases, as well as reduced HRQoL. In multivariate regression analyses adjusted for demographic, clinical, and affective covariates, subjective cognitive complaints (CFQ) remained independently associated with the mental component summary score of the SF-36 (β = -0.47, p = 0.002). Objective cognitive performance (MoCA) was not associated with the SF-36 component summary scores but showed weaker, domain-specific associations in exploratory analyses. The correlation between MoCA and CFQ was weak (ρ = -0.33), indicating a dissociation between these two measures.

Conclusions: One year after mild-grade aSAH, subjective cognitive complaints contribute to mental HRQoL above and beyond the influence of affective symptoms. These findings highlight a clinically relevant dissociation between perceived and objectively measured cognition and support the importance of incorporating patient-reported cognitive difficulties into long-term outcome assessment and rehabilitation planning.
