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?
I'm not a mental health professional. I am a special education teacher and have worked with people with disabilities for several years now. I have never heard of anyone outgrowing PDD. They call it pervasive developmental disorder because it affects almost all areas of one's life and stays throughout the development of their life. People with PDD or autism can still have wonderful lives especially with all the professional help that is out there. Good luck!Does PDD-NOS gradually disappear as they get older?
my nephew has pervasive developmental disorder and his dr said he will always have it. he is 3.5



what we were told to do is when he is playing alone sit beside him and interact by asking him things about the things he is playing with.



he also gets a kick out of trains and plays with them allot so what we do is



ask "do you have a train i can play with?'' if he gives us the train we say "can i play with you ?"



then we ask him questions about the train.



Does your train go fast or slow?

what color is your train?



then tell him about your train.



My train is blue. it goes fast.



My point is talk to her and play with her so she isnt playing by herself allot and maybe she will let others play with her.Does PDD-NOS gradually disappear as they get older?
Children don't 'grow out' of PDD, they learn to cope with it. Host playgroups and be sure you put her in social situations. She may not interact with the other children but she will model their behavior and can learn from them. Socializing her with other people will help more than anything. Good Luck!
