Sniffing Insulin Improves Memory in Alzheimer's Patients!

Alzheimer's and Insulin: The Latest News!

Alzheimer's is a debilitating disease that affects 26 million people around the world. It causes dementia and is fatal. 

Some studies have shown that people with Alzheimer's have reduced levels of insulin in the brain... and insulin is necessary for proper brain function. 

For that reason, Dr. Craft, VA Puget Sound Health Care System and University of Washington in Seattle, presented the findings of a study she orchestrated, designed to measure the effects of insulin on memory loss at a meeting of the Alzheimer's Association in Honolulu.

The results were impressive!

Study participants inhaled insulin daily.

The Study's Results: Insulin Improves Memory!

The study examined 100+ people with Alzheimer's disease (who were not diabetic). It was a controlled study, with two-thirds of the participants receiving different doses of insulin, daily, through a nebulizer. The insulin was sprayed into their noses, twice daily for four months. 

Amazingly, the members of the group who got the lowest doses of insulin, experienced significant improvement in some of the memory tests they were given. Also, researchers found, in study participants who agreed to a spinal tap, that there was a link between improved memory and amounts of key proteins associated with Alzheimer's disease. 

The study also found that the improvement to memory lasted two months. 

Researchers need more studies on the positive effects of insulin and memory loss in Alzheimers' patients.

Madam Aphrodite Speaks...

Dr. Craft says that the results of the study are so encouraging, that further study and clinical trials are required. And I agree! 

This is an important study since current Alzheimer's drugs do not treat memory loss.

      A novel approach although I'm not sure how you can target the brain by introducing insulin nasally. I need to look an see how insulin reacts with the prion proteins which cause the amyloid plaques and neurofibrillary tangles causing memory loss. So little is known about Alzheimer's that the field is wide open to study all manner of possible cures.

      Thank you and kind regards Peter
