Insulin, delivered in a nasal spray, seems to improve cognitive function in Alzheimer's patients, according to research appearing in the Journal of Neurology. Nasal delivery is appropriate because the drug reaches the brain and central nervous system faster. But what is it about insulin, normally associated with diabetics, that helps memory? The researchers say insulin plays a role in the central nervous system and those who suffer from Alzheimer's experience a loss of insulin levels and activity.
Very, very interesting.
