Our DS is 4.5 and is similarly spacey, off in his own world, and forgetful as well. He is very inconsistent though as he will often wake up in the morning and tell us what day it is, whose birthday it is, etc. He reminds me of everything and has and excellent memory. But he will lose and forget things, which I am fairly sure is part of his age. No one has ever mentioned ADHD with him yet, although I have thought that they would as he can be very engergetic and hyper at times. He does not at all have ADHD and I know that only because of my background in that area..but still I could see how gifted children could be misdiagnosed. DS is constantly moving and constantly thinking. I have found that days he is more mentally stimulated he is less physically active though. When I see him getting really antsy I can give him some sort of challenge and suddenly his back on task. But he falls off of his chair almost every day (this is seriously not an exageration) because he can't just sit and eat a meal...he has to do a million things and talk, etc. But if he is really into something using his brain he is much better at sitting (but still falls some). And I have also noticed that when he is spacey it is often because he is thinking of something, doing math equations in his head, listening to something else going on intently (like a tv in the background or a conversation, or music).
