Brief Summary:

Mild Cognitive Impairment (MCI) represents a group of persons who are at risk of incident dementia in the near-term. Persons with MCI who have deficits in short-term recall (amnestic MCI) are at significant risk of incident Alzheimer's disease (AD) (termed prodromal AD), and thus represent a worthy target for secondary prevention interventions.

There is increasing evidence that risk factors for metabolic syndrome (such as prediabetes and type 2 diabetes) increase risk of incident cognitive impairment and possibly AD, and evidence that the neurons of the AD brain are in fact insulin resistant with diminished glucose uptake under physiological conditions. Thus, persons with MCI and prediabetes or type 2 diabetes may be at particular risk of incident cognitive impairment and AD.

A large clinical trial (ACCORD)1 demonstrated that tight control of peripheral blood glucose does not improve cognitive (or other health) outcomes in older persons with peripheral insulin resistance. Thus, there is a need to target cognitive outcomes in persons with MCI and metabolic risk factors, and a drug targeting insulin resistance with good blood-brain-barrier (BBB) penetrance can potentially accomplish these objectives. While there is a phase III study of intranasal insulin targeting this strategy, nutraceuticals offer a low-tech solution that would be more suitable to future secondary prevention trials in MCI.

Bioactive Dietary Polyphenol Preparation (BDPP) is a combination of two nutraceutical preparations grape seed polyphenolic extract (GSE), and resveratrol that contain abundant concentrations of polyphenols. The investigators have found that oral BDPP administration was associated with improved cognition and brain plasticity long-term potentiation (LTP) in mouse models of metabolic syndrome and AD, as well as lowering brain amyloid and tau burden in an AD mouse model2-4. The investigators have demonstrated excellent absorption of oral BDPP in a small study in humans and similarly excellent CSF penetration of oral BDPP in rats, but it is crucial to demonstrate safety and CSF penetration of oral BDPP in humans to assess its potential as a treatment for MCI and prediabetes or type 2 diabetes.
