Mechanisms of Insulin Facilitation of Memory
Completed · Not applicable
Conditions studied: Memory Disorders
In brief
The study described in the present application will test the hypothesis that insulin mediated facilitation of memory in Alzheimer's disease (AD) is achieved through enhanced glutamatergic neurotransmission due to improvements in cerebral glucose metabolism. The effect of a single dose of intranasal insulin on memory and cerebral glutamate concentrations in adults with mild AD or amnestic mild cognitive impairment (aMCI), the presumed prodromal phase of AD will be studied. Successful completion of this study may set the stage for a larger-scale treatment trial of intranasal insulin for adults with memory disorders. However, the use of insulin in this manner at this point in time is purely experimental.
