Objective:
The objective of this study was to identify preadmission and admission factors associated with cognition after hemorrhagic stroke.
Background:
Hemorrhagic stroke survivors may have cognitive limitations. Understanding associated factors can guide surveillance and interventions.
Design/Methods:
Patients with non-traumatic intracerebral or subarachnoid hemorrhage (ICH or SAH) admitted at an urban academic medical center between January 2015 and January 2024 were assessed by telephone 3 months post-discharge using the Quality of Life in Neurological Disorders (Neuro-QoL) Cognitive Function short form. Univariate and multivariate analysis were used to evaluate the relationship between poor cognition (Neuro-QoL t-score ≤50) and preadmission and admission factors in patients with 1) ICH or SAH and 2) ICH only.
Results:
Of 101 patients [62 ICH and 39 SAH; median age 61 (IQR 46-69), 56 (55.4%) with private insurance, 24 (23.8%) with BMI > 30], 51 (50%) had poor cognition 3-months post-bleed. On univariate analysis of both the full cohort and ICH only cohort, poor cognition was associated with (p<0.05): age; insurance type; BMI; and admission mRS, NIHSS, and APACHE II scores. On multivariate analysis of the full cohort, poor cognition was associated with mRS > 0 [OR 4.97 (1.30-19.0), p = 0.019], NIHSS score [OR 1.14 (1.02-1.28), p = 0.026], private insurance [OR 0.21 (0.06-0.76), p = 0.017] and BMI>30 [OR 0.13 (0.03-0.56), p = 0.006]. On multivariate analysis of patients with ICH only, poor cognition was associated with APACHE II score [OR 1.33 (1.07-1.66), p = 0.01], private insurance [OR 0.08 (0.008-0.81), p = 0.033] and BMI>30 [OR 0.03 (0.004-0.28), p = 0.002].
Conclusions:
Cognitive limitations after hemorrhagic stroke are less common in patients with private insurance and BMI>30. Heightened surveillance for non-obese patients without private insurance is suggested. Additional investigation into the relationship between cognition and insurance type and BMI is needed.
