Which parent is responsible for autism?

Does autism come from the mother or father?

The team found that mothers passed only half of their structural variants on to their autistic children—a frequency that would be expected by chance alone—suggesting that variants inherited from mothers were not associated with autism. But surprisingly, fathers did pass on substantially more than 50% of their variants.

Does autism worsen with age?

Goldsmiths, University of London researchers working with adults recently diagnosed with autism spectrum disorder have found high rates of depression, low employment, and an apparent worsening of some ASD traits as people age.

Can autism go away?
