Do you mean all of my dissociative identities? The answer is yes. DID can result in individual identities having different access to certain parts of the brain (for example, certain identities could have aphantasia while others have vivid imaginations), but as far as I'm aware, ADHD is a problem with the brain's reward system itself (the one that has to do with dopamine), so it affects the entire brain function, no matter which part.

However, I've been in situations where different identities can do things that I can't (i.e. switch in order to get out of bed in the morning), so I don't think anything is necessarily set in stone...
