Dementia plaques attack language center of brain

The recent ability to peer into the brain of living individuals with a rare type of language dementia, primary progressive aphasia, provides important insight into the beginning stages of this disease, when it is caused by a buildup of a toxic protein found in Alzheimer's disease. The research also offers insight into why this dementia causes people to lose the ability to express themselves and understand language. The findings will guide Alzheimer's treatment, say researchers.
