GettyResearchers used to think that after adolescence, people were pretty well stuck with the brain cells they’d already formed. And now, a new study from the University of Illinois at Chicago finds that brain cells can form into one’s nineties, even if one has cognitive decline and Alzheimer’s disease (though at a much decelerated rate). The researchers looked at the postmortem brains of people aged 79-99, some of whom had had cognitive decline or Alzheimer’s disease. People with cognitive decline and Alzheimer’s also had evidence of the cells, but in much lower numbers. "The interesting thing is that we also saw some new neurons in the brains of people with Alzheimer's disease and cognitive impairment."
