Scientists looked at the brains of eight people older than 90 who had superior memories until their deaths. They were surprised to find widespread and dense Alzheimer’s plaques and tangles that were, in some cases, considered full-blown Alzheimer’s pathology.
“This is amazing,” said lead investigator Changiz Geula, research professor at the Cognitive Neurology and Alzheimer’s Disease Center (CNADC) at Northwestern University.
“We never expected it. It tells us there are some factors that are protecting their brains and memories against the Alzheimer’s pathology of plaques and tangles. Now, we have to find out what those are.”
