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.

Finding My Own True Voice: Kevin Hancock

Finding My Own True Voice: Kevin Hancock

President of Hancock Lumber Company, a sixth-generation family business, Kevin Hancock (pictured right) has been living with adductor spasmodic dysphonia since 2010. He recently authored the book, "Not for Sale: Finding Center in the Land of Crazy Horse" which is his memoir that traces his journey deep into Indian country, and even deeper into his own soul. More...

In the current issue of Our Voice, Kevin shares some insights on this project and how it impacted his journey with spasmodic dysphonia, "At the time, I was searching for my voice. I was searching for both a path to regain strength in my outer, speaking voice as well as a path to deeper connectivity with my inner voice-the essence of who I am. I believe both voices are connected and SD patients have a unique opportunity to make that connection due to the manner in which the disorder provides a chance to stop, think, and listen." 
Kevin says, "My book explores the notion that we are all here on this earth seeking our own true voice. We all come from a tribe and that tribe pulls on us to act in certain ways. At the same time, each soul is here to individuate - to find its true callings - and, that is only possible when we transcend the busyness and momentum of our own tribes to listen to what our souls are saying. Spasmodic dysphonia is an invitation to listen. It took me quite a few years to realize this, and I doubt I ever would have learned this lesson without SD."
