I am 62. And I can relate. This kind of thing has happened to me off and on over the years; I attribute some of it to fluoxetine (losing words can be a side effect/that blank)---and I do make more spelling and number mistakes than in the past (& with a family hx of dementia I get more uneasy with it with age...but I don't think it has changed much)-------
I do find that anxiety also increases these events. Sometimes the kind of "stress" that I used to welcome.
Lately, I think I have just been "in my head" for too long this time around --- I know physical exercise helps and I have been neglecting that except for periodic outbursts...
What do you think is happening with you? I am curious. Also, I would bring this up again with the doc. next time---you are concerned and That is what matters.
