Teachers more likely to develop speech and language disorders, study finds

Tara Bahrampour:

Teachers are significantly more likely than people in other professions to be diagnosed with progressive speech and language disorders, according to a new Mayo Clinic study.

Speech and language disorders, or SLDs, affect patients' ability to communicate through speaking or writing, rendering them unable to come up with words, produce sentences with correct grammar or articulate properly. It is different from Alzheimer's dementia, which primarily involves loss of memory. SLDs become progressively more severe over time, with death occurring on average between seven and 10 years after onset.

The study, whose results were published this month in the American Journal of Alzheimer's Disease and Other Dementias, came about after Mayo Clinic doctors noticed that a high percentage of their SLD patients were educators.

Using Alzheimer's patients as a control group, the study found that the odds of being a teacher with SLD were 3.4 times higher than being a teacher with Alzheimer's dementia. For other occupations, there was no statistical difference between the SLD group and the Alzheimer's group. The study controlled for the percentage of teachers in the general population as counted in the U.S. Census.
