Is their any one over twenty that has Cah? Would anyone like to compare or talk about problems ? Does anyone have a "normal' life? Please dont be offened if you have children with this problem . and if you want an adult"s opinion who has had Cah (since childhood) I will be glad to discuss the trauma of all the doctor's visits ,tests,ect. As a presonal note dont let your child be viewed by students at teaching schools ,it will have life lasting trauma.
