Healthline - "Study: 'Experienced' Older Brains Process Information More Slowly"
Researchers found that most standard cognitive measures are flawed. The researchers instead used a computer model to read and process information. When the computer was exposed to more data, it processed more slowly, not because its capacity had declined, but rather because it had more data to go through, taking more time. “While this is a hopeful concept, it leads to the same outcome: slower or less efficient processing with age,” said Mary Sano, PhD, Associate Dean for Clinical Research, Professor of Psychiatry, and Director of Alzheimer’s Disease Research at the Icahn School of Medicine at Mount Sinai, adding that more research is needed to explore just how aging affects the brain.
