Yes, I developed a stutter when I was 18! I don’t mind you asking at all! So when I was 18, I started to stutter suddenly and had a host of other symptoms like tics. We had thought that my stuttering was a tic as Tourette’s is something we were dealing with but it turns out my stutter is caused by another neurological disorder where my brain doesn’t send the proper signals to my body, causing a stutter.
