Late-stage pandemic is messing with your brain

The pandemic is still too young to have yielded rigorous, peer-reviewed studies about its effects on cognitive function. But the brain scientists I spoke with told me they can extrapolate based on earlier work about trauma, boredom, stress, and inactivity, all of which do a host of very bad things to a mammal’s brain. “We’re all walking around with some mild cognitive impairment,” said Mike Yassa, a neuroscientist at UC Irvine. “Based on everything we know about the brain, two of the things that are really good for it are physical activity and novelty. A thing that’s very bad for it is chronic and perpetual stress.”
