Insulin Nasal Spray Slows Alzheimer’s

Researchers revealed that a shot a day of insulin in nasal spray form helped to slow effects of Alzheimer’s disease in patients.

The small study looked at 104 patients with mild to moderate symptoms of the disease. The group was split and followed for four months with one group getting a dose of insulin a day. They found that those who had the insulin showed an improvement in their memory and brain function.

“They used a very special device,” CBS News medical correspondent Dr. Jennifer Ashton said on “The Early Show” Tuesday, “that delivered it right into the nose, so it’s not just random insulin.”

“Our results suggest that the administration of intranasal insulin may have a therapeutic benefit for adults with aMCI or Alzheimer’s disease,” Suzanne Craft of the Veterans Affairs Puget Sound Health Care System and the University of Washington School of Medicine, Seattle, and colleagues wrote in the Archives of Neurology.

Experts tempered the find by saying a larger, longer study would need to be conducted. However, they also welcome any advance in the field that has few treatments for Alzheimer patients.

“Anything that shows benefits even in stabilizing a cognitive decline is worth noticing right now. Obviously, like any other study, it has to be replicated and independently confirmed. If that happens, then there will be a lot of interest in moving in this direction,” Dr. Sam Gandy of the Mount Sinai Alzheimer’s Disease Research Center in New York said in a telephone interview.

Alzheimer’s, is the most common form of dementia and is incurable.
