Some scientists are calling this the first real glimmer of hope in the fight against Alzheimer's disease, and it's a nasal spray. The study funded by the National Institutes of Health found that an insulin spray, the same thing used to help patients with diabetes, appears to show memory improvement in some patients with Alzheimer's.
Dr. Laurie Ryan said, "It's very promising. We're very excited about it. We'd like to see it move forward into a larger trial."
About a hundred patients were in this study. After four months, three out of four getting the insulin spray did better on memory tests, and on imaging scans that show brain changes.
So, why insulin? Researchers say insulin helps the body use sugar, and if that doesn't happen properly in the brain, that can lead to memory loss.
A word of warning though…the study says caregivers should not try to treat their loved ones with insulin because that could be dangerous.
Researchers are anxious to start a new and bigger study on this.
