Health literacy is associated with cognition and everyday functioning in a consecutive clinical series of people with epilepsy in a surgical setting.

ABSTRACT

OBJECTIVE: Low health literacy is common among people with epilepsy (PWE) and may play an important role in disease management and outcomes. The current study evaluated whether health literacy is related to cognition, health, and everyday functioning in PWE. METHODS: This cross-sectional, correlational study included 25 demographically comparable healthy adults retrospectively matched to a consecutive series of 89 PWE presenting for neuropsychological evaluation in a surgical setting and who completed the Newest Vital Sign and Brief Health Literacy Screener. The PWE also completed a comprehensive neuropsychological battery and measures of quality of life and everyday functioning. RESULTS: PWE had significantly lower health literacy as compared to healthy adults (ps < 0.05) at a medium-to-large effect size. In analyses covarying for education and oral word reading literacy in the PWE sample, lower health literacy was independently associated with bilateral seizure onsets, greater antiseizure medication burden, poorer performance on measures of memory and information processing speed, and difficulties with self-care (ps < 0.05). SIGNIFICANCE: Findings suggest that PWE are at risk for low health literacy, which may be partly attributable to disrupted brain-behavior relationships and contribute to poorer everyday functioning. Future studies are needed to identify effective methods to support and improve health literacy in PWE.
