The different hemisphere theories is pseudoscience, don't worry about it.

>If I had a child, there is a 60% chance it would have a mental illness and/or learning disability
Do you think your own life was bad? Do you think your own life is not worth living? Then why worry about the small chance your child will end up with the same problems you had. The world needs more high IQ people breeding, not less.

And the chance is small. Where on Earth did you get that 60% figure? Most mental illnesses are nowhere near that heritable. The variation in human brains is governed by a lot of small genes rather than a few big ones. So after sexual reproduction the genes will be all mixed up and the chance of them having your exact problems is minimized.
