As far as I'm aware, autism - and it's extensions - cannot be cured. Some autistics, such as myself, have empathy and some do not. Is empathy a 'learned' trait? My stepson hasn't very much - he's 'learned' what is expected of him in some situations.
I fully agree that pets are a great help with the condition, even if it only teaches people coping mechanisms such as 'learning' appropriate responses and behaviour. In my experience growing up, I always felt an outsider because I couldn't understand people's reactions and emotional responses. I learned that this is what is expected and learned how to mimic it.
This is most evident with grief. I suffer it but it's alien to me to openly show it. I just don't feel like crying or being miserable. I am sad, and unhappy, but inside I miss the person but have completely accepted that they are dead. That's it - awful but what can you do but move on?
