Clinical Trial Summary

The study will test the effects of Peanuts on task-related brain activation and cognitive functions in older adults with memory complaints.

Description:

The purpose of the study is to determine the effects of peanuts on cognitive performance and task-related brain activation on functional magnetic resonance imaging (fMRI) in older adults. The specific aim of the study is to explore the neuroprotective effects of a peanut-enriched diet (2-3 oz of peanuts to replace 20% of the total energy of the habitual diet) for 12 weeks compared to a peanut-excluded habitual diet in elderly men and women with increased risk for CVD and self-reported memory complaints. The study population is older adults 60-80 years in age.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	changes from baseline in Brian activation	Changes will be assessed by Functional MRI (fMRI) on participants. there is no units of measure	baseline to 12 weeks
Primary	changes from baseline serum markers of inflammation	changes in serum inflammation markers which includes hs-CRP, IL-6, TNF-a, ICAM/VCAM, eSelectin, F2-isoprostanes, 8-hydroxy-deoxyguanosine (8-OH-dG) will all be assessed using ELISA	baseline to 12 weeks
Secondary	changes from baseline in global cognitive composite score	The composite score will be calculated using the scores from the tests listed below. We will calculate the standardized scores of each test as the score of each participant minus the group mean and divide by its standard deviation. The composite score is the mean of the standardized scores. the 5 tests are: Rey Auditory Verbal Learning Test (RAVLT), Brief Visuospatial Memory Test, Digit Span, FAS Word Fluency, Symbol Digit Modalities Test	baseline to 12 weeks
Secondary	Change in serum brain-derived neurotrophic factor (pg/mL)	changes in serum brain-derived neurotrophic factor (pg/mL) assessed by ELISA	baseline to 12 weeks
