Mental Attitude: Some Seniors Have Younger Brains.
Individuals who are age 80 and older who possess memories as sharp as those who are decades younger are known in the neuroscience community as “superagers.” According to a new study, the brains of superagers are significantly different than normal seniors with a thicker region of the cortex, far fewer tangles, and a larger supply of neurons linked to higher social intelligence. Study author Dr. Tamar Gefen writes, “Identifying the factors that contribute to the superagers’ unusual memory capacity may allow us to offer strategies to help the growing population of ‘normal’ elderly maintain their cognitive function and guide future therapies to treat certain dementias.”
