For the past 6 or so years, I have had trouble with memory in a certain area.
When someone is spelling out a word to me that I'm not familiar with, I cannot visualize the spelling in my head. I have to ask them to spell it out very slowly, otherwise I cannot comprehend it. The same goes for a series of numbers (for example: a phone number). I know this isn't normal because I don't know anyone else who needs something to be spelled out as slowly as I need it to be.
I have other related things if it will help identify what this could be.
When I want to write or type the following sentence, for example "the boy caught a fish." I will very frequently replace "a" with "i". The same goes vice versa. "However, I am timid." I will frequently put a "a" instead of "i".
What could this be? ADHD? Dyslexia? I haven't had any luck with my online research. Any ideas?
By the way I am a 21 year old male.
Thank you
