Recently read a comment (not a scientific paper) that some in the medical field might feel there was a link between the recent surge in adults recognising ADHD symptoms in themselves and this occurring possibly post- COVID infection. Thinking more of pre existing symptoms worsening in the aftermath of the infection, I can definitely see the possibility. My own traits worsened significantly after childbirth.
I have no particular argument to make about this. Some will no doubt say it's bollocks, but we can't dispute the huge numbers of people recognising this profile now, since 2015. Could there be a link?
Again this is not saying people don't have ADHD, but that getting COVID exacerbates the existing traits.
