Does PDD-NOS gradually disappear as they get older?

I've heard from several sources that unlike other branches of autism like Aspergers, PDD-NOS can be outgrown or disappears in adult life. Can I get some input from some mental health professionals with experience with people with it? My 4 year old daughter was just diagnosed with it and she loves trains and spends most if not all of her alone time jumping and flapping her arms in a corner and talking to herself under her breath. I love her to bits. I'm just wondering if it will stay with her as she grows up. Any help will be strongly appreciated.Does PDD-NOS gradually disappear as they get older?
My 2.5 year old also has PDD-NOS and I was told the same thing by a pediatrician. I honestly don't think they totally outgrow it but that because it is less severe than classic autism its possible for them to overcome a lot of the symptoms which would cause them to loose the PDD-NOS label. I do think that some things will still stay with them when they grow up but it will likely be so mild that it will be unnoticeable by anyone who doesn't know she had been diagnosed as PDD-NOS.

Many parents are recovering their children by reversing the symptoms of autism so I do think that it could be possible to completely overcome PDD-NOS using biomedical treatment. If you want some more info on it here are some good websites
