Partnering with you in the treatment of spasmodic dysphonia and related voice disorders

Spasmodic dysphonia and related voice conditions can be difficult to diagnose and even more difficult to treat because most have no cure, only symptom alleviation.

In a survey of 750 SD patients conducted by the NSDA,

  • 70% had more than one diagnosis before they were finally diagnosed with SD,
  • 22% of those had greater than 3 different diagnosis prior to their SD diagnosis. 
  • 52% said that it took between 1-6 years from the onset of symptoms to get an SD diagnosis. 

In another survey, patients took an average of 4.43 years (53.21 months) to be diagnosed with SD after first going to a physician with vocal symptoms

Onset of Symptoms

While the onset of SD is most prevalent between the ages of 40-49, a survey of 754 SD patients shows that SD can occur at any age.

Gender

SD seems to affect females more than males.

We hope to serve as a resource for you and your patients. Thank you for dedication and commitment to the Voice community.
