I’m by no means unable to read or comprehend text, I’m smart enough for life and people often compliment my intellect. Big tickets on myself I know.
However when it comes to reading anything it often takes me twice as long, just a meme with text or anything.
If I don’t concentrate on it I miss words or like an Ai hallucination I put random words into the sentence or muddle them around making things often hilarious for myself until I re read the text to get the actual meaning.
There are plenty of possibilities from ADHD to dyslexia. You should consult a professional if this is a major concern to you.
