Mental health question! A man.. he’s probably in his late 50s.. I don’t know if he has PTSD or brain damage or what?

He has this creepy laugh that I feel like he can’t control …and when he’s drinking his eyes roll.. he said he thinks somethings wrong with his brain.. at first I thought he was doing it intentionally but now I think he can’t helps it.. and now I feel bad for thinking he was just being a crazy ass..

what do you think it is?

He’s intelligent. Extremely intelligent and he can hold a convo. But out of the blue.. I don’t know if it’s stress that triggers it or what. We work in a highly busy, stressful environment
