People with a rare kind of dementia that initially attacks the language center of the brain end up recruiting other areas of the brain to decipher sentences, according to a new study.
The study is one of the first to show that people with a neurodegenerative disease can call upon intact areas of the brain for help. People who have had strokes or traumatic brain injuries sometimes use additional regions of the brain to accomplish tasks that were handled by the now-injured part.
“We were able to identify regions of the brain that allowed the patients to compensate for the dying of neurons in the brain,” says first author Aneta Kielar, an assistant professor of speech, language, and hearing sciences and of cognitive science at the University of Arizona.
