It is only speculation at this point.

This is not unusual for highly creative people – many very very famous, of course Virginia Woolf comes quickly to mind. I have a friend who had been autistic as a child, grew out of it (or just adapted to the outside world), was a very energetic woman, talented artist, creative on many fronts (thanks surely to whatever crossed wires had attributed also to her autism) but also suffered severe, inexplicable depression and eventually committed suicide. It was a heartbreaking loss of a person who brought so much joy to so many people.
