After a year of lockdown, many of us are finding it hard to think clearly, or remember what happened when. Neuroscientists and behavioural experts explain why

Before the pandemic, psychoanalyst Josh Cohen’s patients might come into his consulting room, lie down on the couch and talk about the traffic or the weather, or the rude person on the tube. Now they appear on his computer screen and tell him about brain fog. They talk with urgency of feeling unable to concentrate in meetings, to read, to follow intricately plotted television programmes. “There’s this sense of debilitation, of losing ordinary facility with everyday life; a forgetfulness and a kind of deskilling,” says Cohen, author of the self-help book How to Live. What to Do. Although restrictions are now easing across the UK, with greater freedom to circulate and socialise, he says lockdown for many of us has been “a contraction of life, and an almost parallel contraction of mental capacity”.

This dulled, useless state of mind – epitomised by the act of going into a room and then forgetting why we are there – is so boring, so lifeless. But researchers believe it is far more interesting than it feels: even that this common experience can be explained by cutting-edge neuroscience theories, and that studying it could further scientific understanding of the brain and how it changes. I ask Jon Simons, professor of cognitive neuroscience at the University of Cambridge, could it really be something “sciencey”? “Yes, it’s definitely something sciencey – and it’s helpful to understand that this feeling isn’t unusual or weird,” he says. “There isn’t something wrong with us. It’s a completely normal reaction to this quite traumatic experience we’ve collectively had over the last 12 months or so.”

It’s likely that in a year or two, we’ll look back on some event this year and say, when on earth did that happen?

It is the cognitive equivalent of feeling emotionally distressed – it’s almost the way the brain expresses sadness

People are finding themselves more sluggish – their physical and mental weight is somehow heavier, hard to carry around
