What we are studying

This research study is to find out whether insulin aspart improves memory when administered as a spray into the nasal passages of adults with mild memory impairment or early Alzheimer’s disease. We will explore the effects of insulin aspart administered intra-nasally on memory and levels of certain hormones and proteins in the blood. Insulin is approved by the US Food and Drug Administration (FDA). However, using it in this way is experimental and we don’t know if it will be effective to help improve cognition.
