What Could Be Causing Cognitive And Motor Changes Like When I M Struggling With Focus, Memory, Word Recall, And Typing Fluidity?

Lately, well more than lately, I have noticed that I am having a harder time focusing, retaining information, staying on tasks, staying interested in a task. My mind wanders and I noticed it s hard to stay focused on what I am doing. I also notice it s harder for me to formulate thoughts and words aren t coming as easy to me as they used to. Also, and this may be unrelated but I notice I can t type as fluidly as I used to (almost as if one hand is moving at the normal pace but the other lags)
