@cstross I thought I'd escaped long COVID, until Farah mentioned her memory problems in her speech at Eastercon. Then it dawned on me that the worsening of my memory problems might not be just a flare-up of my chronic migraine symptoms.
I'd also had an increase in "putting the milk away in the mug cupboard" episodes. Pterry wasn't the only person with early onset dementia I've known, so I noticed that. I was a lot better after a year. Some people won't be, and won't notice.
