<human>: I've gone out with this guy about 5 times. He's fantastic, but sometimes he moves his shoulders/head/hands in a way that makes me wonder if he's in complete control of himself physically. It's not quite Parkinson's level but it seems worse than just a simple nervous twitch.  

Our dates have been 'activity' dates thus far so I'm not terribly surprised he hasn't mentioned anything. He seems to really like me, I really like him. I'm hoping he'll tell me about it soon enough when we get to that stage of a relationship, but I guess I just wanted to get some preemptive advice for how to handle it if he doesn't.   

1) It's weird to me to imagine a relationship with someone where something like this is never brought up. I'm nearly sure I would get asked about it, and I'm not comfortable having a relationship where my response would be "Yeah I just have no idea" if we'd been dating for several months. Which makes me wonder if:  

2) Maybe he doesn't realize he's doing it? My aunt has a pronounced facial tick and both my dad and I think she doesn't know, it's never been addressed before. I don't want to say "Hey, so, what's up with this?" and have him be like "What are you talking about?"  

3) Our relationship is just starting, we've not slept together even, I'm fine not knowing right now but I know there will come a point where I do feel I want to know and I don't know how to bring that up if he doesn't. I'm 100% okay with dealing with this but I'm not okay just having no idea.  

*Hopefully* he just says to me in a few dates "Oh by the way, I have ____" but I just wanted to prepare myself for what to do should that not happen, and how the best way to address that is.

Can you summarize the given text in a few sentences?
<bot>: My new love interest has some sort of movement disorder, I'm not sure if/when/how to bring it up should he not. Anyone with any experience in this area, I would appreciate advice!
