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.

World Voice Day 2018 - Cherish Your Voice!

World Voice Day is celebrated every April 16th with the main goal of increasing public awareness throughout the world of the importance of the voice and impact of voice problems. The year’s World Voice Day theme is “Make the Choice to Cherish Your Voice.” On April 1, the NSDA will begin a video campaign on social media channels. Each day we will post a video highlighting an aspect of living with spasmodic dysphonia and related voice conditions. We encourage you to share the videos or ‘like’ them depending on the social media platform you are on. Find the videos here: http://bit.ly/2uzXEQW More...

As anyone with spasmodic dysphonia and related voice conditions can attest, the loss of normalcy in the voice has major implications to all facets of your life. Although the voice is used as an everyday basis of speech, most people realize its importance only when a voice problem arises. By creating awareness, vocal issues can get more acknowledgements, more funding, and more research to promote future treatments or even a cure.

We are also including a sign that offers the message “cherish your voice.”  We hope you will join us by:

1.  Printing the sign by downloading here

2.  Take a picture with the sign

3.  Post it on your own social media on April 16 to show your support of World Voice Day

4.  Link to our Facebook page so we can see them too.

Encourage your friends and family to participate too and support you! You can even do a short video and share why you cherish your voice. This is a celebration of the power of all voices regardless of how they sound!

If you are not on social media, you can still participate! Snap your photo with the sign and email it to us at NSDA@dysphonia.org with your permission to share the photo. We will post them.

We hope you will "make the choice to cherish you voice" and participate in this campaign! We appreciate you continuing to share your stories and participating in advocacy with us. Awareness is a critical measurement that influences early diagnosis, best treatment practices, funding for research and hopefully, cures.  World Voice Day on April 16 helps support these goals!
