Even if they’re still within the normal range, higher glycated hemoglobin (HbA1c) levels may be associated with poorer performance on certain cognitive tests and with differences in hippocampal structure, German researchers found. Among healthy middle-age and older adults with mean HbA1c levels of 5.8%, each standard deviation increase in HbA1c was associated with significant declines in delayed recall, learning ability, and memory consolidation… They added that “lifestyle strategies” to achieve strict glucose control could prevent age-related cognitive decline, even in individuals with HbA1c levels currently considered normal — a hypothesis that should be tested in future trials, they noted.
