Why is stuttering still so misunderstood?

Recently medical experts agreed on the first consensus medical guidelines on stuttering. It's a step forward for a condition that affects more 400,000 Canadians. Alexandra D’Agostino-Seguin has lived with a stutter since she was in elementary school and talks about how that experience has shaped her. Her mother, Eeva Stierwalt, is a National Coordinator at the Canadian Stuttering Association and reflects on what it was like to raise a child who stutters. Dr. Gerald Maguire, founder of the Stuttering Research and Treatment Society, talks about his hopes for better treatment for the condition.
