Location: Boston, Massachusetts2013 Annual Report
1a. Objectives (from AD-416):
1. Establish the effects dietary berry fruit extracts and/or fatty acids on behavioral and neuronal deficits in aging to assess the mechanisms involved and the most effective polyphenols/fatty acids in animal and human models. 2. Determine the effects of the berry and/or fatty acid dietary supplementation in altering putative decrements in gait, force, and balance in aged humans.
1b. Approach (from AD-416):
The purpose of this project is to translate our previous findings showing that blueberry BB supplementation in senescent rodents reversed both motor behavioral and cognitive deficits to humans by determining if BB given to aged humans would reduce gait abnormalities (stride length, stride width and balance) and cognitive (memory) deficits.
3. Progress Report:
Functional changes in the brain and motor neurons during aging can alter learning and memory, gait, and balance - in some cases leading to early cognitive decline, disability, or injurious falls among older adults. We are exploring the effects of dietary supplementation with blueberry on age-related alterations in balance, gait, and cognition in older men and women (60-75 years old). During this year, 75% of the required participants have been recruited into the study and begun their active participation in the study. Half of the participants have completed their participation in the study. Biological samples are being stored for analysis. Data collection is expected to be complete by December 2013.
