"Individuals who were considered to have high normal blood sugar
levels - meaning below but close to 6.1 mmol/l (110 mg/dL) - had more
brain loss in the hippocampus and the amygdala than those who had
lower blood sugar levels. These areas are involved in memory and
cognitive skills. Loss in brain function is characteristic of diseases
of dementia including Alzheimer's, according to the National
Institutes of Health."

"These findings suggest that even for people who do not have diabetes,
blood sugar levels could have an impact on brain health," Cherbuin
said. 'More research is needed, but these findings may lead us to
re-evaluate the concept of normal blood sugar levels and the
definition of diabetes.'"
