Improving the Quality of Memories
One of the most devastating aspects of Alzheimer's is its effect on patients' ability to recall life events. Several studies have found that music helps to strengthen these individuals' autobiographical memories, and a paper in the November 2013 Journal of Neurolinguistics builds on these findings by exploring the linguistic quality of those recollections.
Researchers instructed 18 patients with Alzheimer's and 18 healthy control subjects to tell stories from their lives in a silent room or while listening to the music of their choice. Among the Alzheimer's patients, the music-cued stories contained a greater number of meaningful words, were more grammatically complex and conveyed more information per number of words. Music may enhance narrative memories because “music and language processing share a common neural basis,” explains study co-author Mohamad El Haj of Lille University in France.
