Language Skills In Your Twenties May Predict Risk Of Dementia Decades Later

ScienceDaily (July 9, 2009) — People who have superior language skills early in life may be less likely to develop Alzheimer's disease decades later, despite having the hallmark signs of the disease, according to research published in the July 9, 2009, online issue of Neurology®, the medical journal of the American Academy of Neurology.

"A puzzling feature of Alzheimer's disease is how it affects people differently," said study author Juan C. Troncoso, MD, with Johns Hopkins University in Baltimore. "One person who has severe plaques and tangles, the telling signs of Alzheimer's disease in their brains, may show no symptoms affecting their memory. Another person with those same types of plaques and tangles in the same areas of the brain might end up with a full-blown case of Alzheimer's disease. We looked at how language ability might affect the onset of symptoms."
