I recently did a presentation on stuttering in college. One thing I enjoyed talking about was the treatments, especially the ones that I've been taught by SLP's that don't work and are just bogus. Another topic that could be brought up is how the treatments of stuttering have evolved over time. My presentation was about an 8-minute speech, so there were more stuttering based topics in there too! I definitely think that stuttering would be a good topic, there's a lot that could be written about! If you decide to do it and need help brainstorming specific ideas just PM me!
