When an older adult tells a doctor their memory has worsened over the past six months, that report often does not align with their cognitive test scores. Researchers at UC Davis Health tried a different approach and got a different result.
Instead of asking people to summarize months of experience in a clinic, they gave 162 older adults Apple Watches and prompted them four times a day for a week to rate how sharp their thinking felt at that moment. Participants also completed brief tasks measuring processing speed and attention on the watch at those same moments.
