This study will test the hypothesis that recurrent hypoglycemia is associated with differences in cognition (thinking), by analyzing results of cognitive testing in individuals with a history of hypoglycemia as compared with those without known hypoglycemia.
This pilot study will identify cognitive domains of interest in participants with hypoglycemia, as well as inform the development of a future battery of assessments, which could be replicated in a larger sample. Cognitive domains which will be assessed include: memory, language, executive function, and psychomotor speed.
