Trouble talking

Hello. I have autism spectrum, around Thanksgiving last year I was diagnosed with iih as well with my pressure being 41. When I talk it's hard to get the words out sometimes and get the words to make sense. My thoughts are not as clear anymore. They used to be so detailed. Now my thoughts seem vague. My memory is getting bad. I used to be a savant and say hello in 42 languages and recognize over 340 breeds of dogs, I can't do very much any more.
