Hypoglycaemia affects executive function

The glucose clamp study in 32 people with and without type 1 diabetes showed that executive functions, including verbal fluency, sorting and spatial planning, were impaired during hypoglycaemia.

Hypoglycaemia prolonged the time to complete all tests and the lower scores achieved were not only a result of slower processing time, but also due to greater errors compared with euglycaemia conditions.

Patients with type 1 diabetes were affected to a greater degree by hypoglycaemia than those without diabetes on many of the tests.
