High intelligence is also associated with the following:

1) not fitting in socially;

2) higher awareness of things.

Neither of these are good for anyone's mental health, but they're not problems directly caused by intelligence itself. Their combination is especially bad, as one could be aware of potential problems while others aren't, generating all sorts of friction.

I believe higher intelligence simply requires better personal mental health management, but there isn't really anywhere for people to learn that and I would say our current philosophical assumptions do not facilitate it.
