I'll try gathering some more or relevant information about it....but thanks a lot for your reply....
Conversion disorder is achild so young would be very unusual and on the face of it I have to say that such a diagnosis is very questionable. While your description does not include sufficient details to comment in any specific fashion, your data invite more of a medical (including neurological) condition that a psychological condition. Thus, more by way of medical workups, not psychological evalaution, is warranted.
