Hello, thank you for the information. In recent years' conferences and meetings, what is the global perspective regarding those who stutter at a severe level? Time goes by, and it still seems like everything is focused on optimizing treatment for children and adolescents. However, as an adult, one feels hopeless that anything new will come out, and it's often just Van Riper and the same therapies that have never radically changed the condition of someone with severe stuttering.
