MedPage Today (8/7, George) reports a study found that “superagers – a group of adults over age 80 with the memory capacity of much younger people – maintained good brain morphology, tended to be gregarious, and appeared to be resistant to neurofibrillary degeneration and resilient to its consequences.” Researchers observed that “in contrast to neurotypical peers who had age-related brain shrinkage, this group had a region in the cingulate gyrus that was thicker than younger adults.” Furthermore, “superagers also had fewer Alzheimer’s-related brain changes, greater size of entorhinal neurons, fewer inflammatory microglia in white matter, better preserved cholinergic innervation, and a greater density of evolutionarily progressive von Economo neurons.” They noted that no particular lifestyle was conducive to superaging. The study was discussed in perspective piece published in Alzheimer’s & Dementia.(SOURCE: APA Headlines)
