I read Ralf Dahm's article "Finding Alzheimer's Disease" (March-April) with interest for two reasons. First, as a cognitive neuroscientist, I have studied the effect of early-stage Alzheimer's disease on memory and on the appreciation of music and art. In addition, I am a member of a community chorus here in Pennsylvania, the Susquehanna Valley Chorale, which recently commissioned and premiered a choral work on the topic of the ailment, called Alzheimer's Stories.
