PMID 39044609WHAT IT FOUND
Adults with type 2 diabetes reported significantly worse perceived cognitive function than the US average.
High glucose variability and frequent hypoglycemia were strongly linked to these self-reported deficits, while objective cognitive test scores remained within the average range.
Key findings
01Participants reported perceived cognitive dysfunction significantly higher than the US population average.
02Greater glucose variability and more time spent in hypoglycemia were strongly associated with worse self-reported cognitive function.
03There was no significant correlation between how participants felt their cognition was performing and their actual scores on objective cognitive tests.

What it does not show
The sample size was small, which may limit the statistical power of subgroup comparisons. The recruited sample may not be generalizable to the broader population with type 2 diabetes. More detailed information on diabetes history and cognitive function was not available at baseline. All data were obtained at baseline, so causal relationships between glucose variability and cognitive function cannot be determined.
Declared interests
The authors declare that there is no conflict of interest.
The easy way to misread this
Do not assume that a patient's self-reported cognitive deficits are backed by objective cognitive impairment. The study found no significant correlation between subjective complaints and objective test scores, meaning patients may feel cognitively impaired while performing within the average range on standard tests.
