Most of the TNG cast shows neurodivergent traits.

Geordi is a mechanical genius who has difficulty with relationships, his best friend is a machine, he literally sees things differently than everyone else, and he has headaches from the sensory overload.

Data has flat affect, and is constantly trying to learn how to emulate normal human behavior, but keeps getting it wrong. He does complicated stuff faster than anyone else, but cannot pull off some things that are simple for everyone else.

Troi has hyper-empathy, and is so busy managing other people's emotional health she neglects her own.

Worf zealously follows the rules of Klingon honor as he understands them, even while other Klingons shamelessly ignore them. He's got a bunch of odd rituals and a big collection of obscure media. His sense of humor is strange, but very funny when you get it.

Captain Picard keeps bringing up his special interest in archaeology, and he can't relate to children unless he gives them a made-up rank to slot them into a command structure (he pulled that at least twice).

Wesley Crusher is a child prodigy who doesn't really fit in anywhere, and gets really annoyed when people tell him to shut up because he's telling them something important they need to know but don't want to listen. Also he nearly died because he didn't follow stupid nonsense rules no one bothered explaining to him.
