Summary

The purpose of this study is to determine if there is a relationship between recurrent hypoglycemia (low blood sugar) and cognition (thinking) in individuals who have a history of hypoglycemia, but do not have pre-diabetes or diabetes.

This study will analyze whether recurrent hypoglycemia is associated with differences in cognition (thinking), and if individuals with a history of hypoglycemia perform less well on cognitive assessments compared to individuals without known hypoglycemia.

Description

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.
