Dear Batya Yasgur,
My apologies as I know you are on a deadline. With the holidays combined with travel, I have been in and out checking comments. May I confirm if this is the presentation to which you are referring: “Music As A Protective Factor Against Dementia And Cognitive Impairment: A Twin Study” presented by Dr. Alison Balbag University of Southern California, CA? The author is different than the one you referenced, but they may be the same presentation.
