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.

New Grant Co-Funded by the NSDA

The NSDA is pleased to announce that it is jointly funding a grant on genetics and spasmodic dysphonia with the Dystonia Medical Research Foundation. The grant, "Identification of a Spasmodic Dysphonia Gene using Exome Sequencing," is being led by Tatiana Fuchs, Ph.D., with Laurie Ozelius, Ph.D., serving as a significant contributor. Both researchers are located at Mount Sinai Medical Center in New York. More...

This grant is focused on finding a possible genetic cause of spasmodic dysphonia. Dr. Fuchs is using an innovative, powerful technique to screen all genes in a family affected by SD to identify a common gene mutation. To determine whether mutations in this gene contribute to additional SD and other focal/segmental primary dystonia cases, Dr. Fuchs will also screen for this gene in an additional group of volunteers with focal dystonia. This research may reveal a new causative gene for SD and possibly other forms of primary dystonia, contributing to our understanding of the disease mechanism and providing a basis for development of new therapies.

 


Dystonia Advocacy Network Insurance Survey Needs Volunteers

The Dystonia Advocacy Network has opened the insurance survey for 2012 and needs members of the NSDA to share their insurance/reimbursement experiences. The survey, meant for individuals with all forms of dystonia, is researching the direction of the insurance industry as well as using the information to form strategies to close gaps with current and future insurance problems. The survey is only open until September 15, 2012, so please participate today. The survey is completely anonymous, and we appreciate your help. Thank you! Click here to access the survey website.

Increase in NIH Funding of SD Grants

Currently, there are 13 grants for SD research funded through the National Institutes of Health. This is a huge increase over the last five years when there have been only a handful of grants specifically on SD. This new research is focused on a wide spectrum of areas including neuro-imaging, epidemiology and pathophysiology. Scientific Director Dr. Christy Ludlow lauded the efforts of the NSDA and its advocates in raising the profile of SD in the research community. Dr Ludlow strongly encouraged all to keep up the work of advocacy and support for SD as it is making a difference. More...

Snowdon Climb a Huge Success

Snowdon Climb a Huge Success

By Anne McDougall: On 24th June 2012, thirty one eager but mostly inexperienced individuals, set out to climb Mt Snowdon in North Wales, UK in aid of the National Spasmodic Dysphonia Association. The group comprised family, friends and colleagues, and consisted of all age groups, including a little girl aged seven and a dog called Ruby. The climb of Snowdon (the highest mountain in England and Wales, elevation 3560 feet or 1085 m) was organised by Anne McDougall, an SD patient, with her husband John taking up the challenge on her behalf. More...

We all met in the car park at the bottom of the mountain and after a few group photographs the ascent commenced in cloudy damp conditions. The weather in the UK had been atrocious for weeks  but no one expected the conditions on the mountain to be quite so challenging.  Very soon on the way up the conditions began to deteriorate; the cloud came down, the rain started and the mist rolled in. 

These intrepid supporters all pushed bravely on as I passed, waving at them from the relative comfort of the rickety, cramped, damp old train. On my arrival at the top there was thick fog, driving rain and it was blowing a gale. I imagined that many of the group would have turned back but with true grit everyone eventually arrived at the cafe at the top. All in good spirits, cold and wet, but laughing about their experience and their individual struggles to reach the top. John made sure everyone had arrived safely, gallantly going back to find and help a few stragglers.

Once everyone was refreshed with a hot drink, many were eager to start their descent, as the return can be more challenging that the upward climb. I began my journey down by train feeling inspired by all of them, and also feeling somewhat guilty that they had all put themselves through this for me.

At the bottom the weather had improved dramatically; the sun was out and it was warm. Later during the afternoon individual small groups began to arrive at the bottom and gather in the square for a drink, tired but elated by their success and willing to swap their experiences with fellow trekkers. One topic of conversation was “What shall we do next?”

I am inspired by them all and I thank every single one of them for their time, energy and contribution in making this a very successful fund raising event. Our aim was to have raised a few thousand  dollars for NSDA – to help finance their mission of awareness, research and support  for people with SD.
