Curious to know if anyone has experienced the AuDHD/ADHD regression?

I feel like growing up I was obsessed with books and learning new information and was really good at communicating and even writing.

Now it feels like I can barely string together coherent words altogether to make sense. Similarly, I try to read books only to feel extremely discouraged because I can't comprehend major parts of it. It also stands true for even basic text messaging where I just struggle with comprehension.

It's extremely frustrating and I'm in my mid 20s. I wonder if there's a way around this 😢
