What is Spasmodic Dysphonia?

Spasmodic dysphonia (SD), a focal form of dystonia, is a neurological voice disorder that involves "spasms" of the vocal cords causing interruptions of speech and affecting the voice quality. SD can cause the voice to break up or to have a tight, strained, or strangled quality.

Several researchers, some who are funded by the NSDA, including Drs. Kristina Simonyan, Mo Chen, Michael Hammer, and Rita Patel, shared their different approaches to better understanding spasmodic dysphonia, After lunch, Dr. Laura Froeschke talked about how spasmodic dysphonia can affect your identity, and Speech Language Pathologists Jan Potter Reed and Brienne Ruel provided voice therapy tips and recommendations in break-out sessions. One person commented, "It was great meeting so many people who understood what I was going through and not being embarrassed to speak," and another said "What I enjoyed was the variability of approaches to SD research, various treatment options, and integrating the problems of SD in our lives." Our thanks to all who attended!
