http://www.sciencedaily.com/releases/2013/10/131015094508.htmIn the study, researchers looked at a group of about 100 patients with speech and language disorders and noticed many of them were teachers. For a control, they compared them to a group of more than 400 Alzheimer's patients from the Mayo Clinic Study on Aging. Teachers were about 3.5 times more likely to develop a speech and language disorder than Alzheimer's disease. For other occupations, there was no difference between the speech and language disorders group and the Alzheimer's group.
When compared to the 2008 U.S. census, the speech and language cohort had a higher proportion of teachers, but it was consistent with the differences observed with the Alzheimer's dementia group.
I find this baffling. Is the implication that people with latent progressive speech disorder are attracted to teaching, or is it that teaching exacerbates some universal vulnerability to this condition?
