Did Agatha Christie Have Dementia?

As a counselor to family caregivers, many of whom care for a loved one with dementia, this article caught my attention today. How fitting that I had just finished my Agatha Christie book review a few minutes before. (That particular book was first published in 1950 – when Christie was 60.) Commentors on the article had mixed opinions about the validity of the study, but based on my experiences so far and other research I’ve read, I wouldn’t write it off as nonsense.
