Memory research roundup - Blueberries

In the last post, HDL cholesterol levels appear to have a positive effect on memory recall (or at least arrest its decline). On a similar dietary theme:

Scientists Find Blueberries Reverse Age Related Memory Deficits

Researchers (from the Schools of Food Biosciences and Psychology in Reading and the Institute of Biomedical and Clinical Sciences at the Peninsula Medical School in Exeter) supplemented a regular diet with blueberries over a three month period. Within three weeks, they discovered improvements in spatial working tasks and the improvements continued throughout the course of the study.



The enhancement of both short-term and long-term memory is controlled in neurons (brain cells) at the molecular level. The researchers think flavonoids found in blueberries may help learning and memory by enhancing existing neuronal connections, improving communication between cells and stimulating the regeneration of neurons.

The scientists were able to pinpoint the ability of flavonoids to activate signaling proteins in a specific area of the hippocampus, the learning and memory-controlling part of the brain.
