Brain fog? Why you may be struggling to think clearly — and how to beat it

[superadmin]

If you’ve struggled to think clearly during the coronavirus pandemic, you could be experiencing “brain fog” – and one neuroscientist has explained how to beat it.

“Brain fog is a collection of symptoms which give rise to loss of mental clarity or foggy thinking,” Sabina Brennan wrote in her recently published book “Beating brain fog.” 

While there are no statistics on the prevalence of brain fog specifically, Brennan highlighted that around 600 million people worldwide suffer from cognitive dysfunction, which she said is a clinical description of this issue. 

Difficulty thinking clearly has also been noted as one of the debilitating symptoms of “long Covid.” But even if you haven’t had the coronavirus this past year, Brennan told CNBC you might still have experienced brain fog and outlined some ways to overcome it.
