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.

Dot Sowerby's Senior Games 'Fun Raiser' to Support SD Research

NSDA Past President Dot Sowerby, 82 years young, has been running for over thirty years. She started with a jog around the block, but now, she is participating in the National Senior Games. This year’s competition will be held in Minneapolis, MN, from July 5-11, and Dot will be competing in the Running Long Jump, 100 Meter Dash, 200 Meter Dash, 400 Meter Dash, 800 Meter Run, 1500 Meter Run, and 5K Run (3.1 miles). When she returns again this year, this avid competitor will be also raising funds for spasmodic dysphonia research. More...

Besides Dot's age and athletic ability, she has a rare neurological voice disorder called spasmodic dysphonia (SD) which causes the vocal cords to spasm shut making communication very difficult. “Around the time I started running, I began having problems with my voice. At first I felt scared and panicky that I would never have a normal voice again. I remembered the running support group that fostered me, so I looked for voice support groups. It linked me up with the National Spasmodic Dysphonia Association. My friends in the voice support system encouraged me and taught me ways to cope and medical options to look into,” Dot shared.

Dot was recently honored at the NSDA Symposium with establishment of the “Dot Sowerby Pioneer Award” to recognize her many accomplishments in raising awareness about spasmodic dysphonia. Once again, Dot pushes forward, utilizing this opportunity to help raise funds for the NSDA. Please join us in supporting Dot by making a donation to the National Spasmodic Dysphonia Association by going to www.dysphonia.org/donate.php and click on the "Please credit this donation to" and select Dot Sowerby's Senior Games Fund-Raiser.

My early days of running were difficult but I persisted and slowly improved.  I receive support from a local running group. There were not many females running in the 1970’s, as most women my age did not grow up participating in track.  I eventually ran a half marathon (13 miles).

In 2010, I started competing in the local Senior Games. I had to qualify in my city, then went to state games and earned the right to participate in National Senior games. Over time, I have won about 60 metals locally and nationally within my age group

Running helps me physically, mentally, and spirituality. When you run, you get endorphins, in your body, which makes you feel good. I also listen to music when I walk or run and feel like I get a “double shot” of endorphins.

Life does not always give awards for overcoming challenges. My voice achievements are just as important as my winning metals for running. You can progress beyond obstacles in your life and try new activities. I hope others will be encouraged to keep moving forward!

Alcohol Responsiveness in Laryngeal Dystonia: A Survey Study

Dr. Kristina Simonyan and her research team at the Icahn School of Medicine at Mount Sinai, New York, conducted an on-line research study to investigate the effects of alcohol on symptoms of dystonia and tremor in a large population of patients. They have recently published the results of this survey and below is the abstract and lay summary. We thank all those in the SD community who participated in this survey. More...

Lay summary of research
It has long been noted by patients and physicians alike that alcohol improves the symptoms in many patients with spasmodic dysphonia. However, this anecdotal finding has never been confirmed. Thanks to the NSDA community, we were able to survey 641 patients with isolated spasmodic dysphonia (SD, or laryngeal dystonia) and with spasmodic dysphonia combined with voice tremor (SD/VT). We found that more than half of patients in both groups thought that their voice symptoms improve to some extent after drinking alcohol. Patient’s family and friends also noticed similar improvement. The duration of effect of alcohol on voice symptoms was thought to last 1 – 3 hours in both patient groups. Although alcohol is an interesting and potentially powerful agent, the results of this survey study do not imply or recommend alcohol consumption in any form in order to treat SD symptoms. However, this information may help us, the researchers, to start thinking about new and alternative pharmacological agents with effects similar to alcohol in order to develop more efficient treatment options for SD and other dystonias.

Abstract
Laryngeal dystonia (LD) is a task-specific focal dystonia of unknown pathophysiology affecting speech production. We examined the demographics of anecdotally reported alcohol use and its effects on LD symptoms using an online survey based on Research Electronic Data Capture (REDCapTM) and National Spasmodic Dysphonia Association’s patient registry. From 641 participants, 531 were selected for data analysis, and 110 were excluded because of unconfirmed diagnosis. A total of 406 patients (76.5%) had LD and 125 (23.5%) had LD and voice tremor (LD/VT). The consumption of alcohol was reported by 374 LD (92.1%) and 109 LD/VT (87.2%) patients. Improvement of voice symptoms after alcohol ingestion was noted by 227 LD (55.9% of all patients) and 73 LD/VT (58.4%), which paralleled the improvement observed by patient’s family and/or friends in 214 LD (57.2%) and 69 LD/VT (63.3%) patients. The benefits lasted 1-3 hours in both groups with the maximum effect after 2 drinks in LD patients (p = 0.002), whereas LD/VT symptoms improved independent of the consumed amount (p = 0.48). Our data suggest that isolated dystonic symptoms, such as in LD, are responsive to alcohol intake and this responsiveness is not attributed to the presence of VT, which is known to have significant benefits from alcohol ingestion. Alcohol may modulate the pathophysiological mechanisms underlying abnormal neurotransmission of γ-aminobutyric acid (GABA) in dystonia and as such provide new avenues for novel therapeutic options in these patients.

Dilbert Creator Scott Adams Delivers Keynote Address at NSDA Symposium

Dilbert creator Scott Adams delivered the keynote address at the 2015 NSDA symposium on May 16, 2015 in San Francisco. Having struggled with spasmodic dysphonia since 2005, the popular cartoonist is now helping to spread the word about SD and to support others who are living with the challenge of this neurological voice disorder.   More...

NSDA President Charlie Reavis expresses appreciation to Adams for his participation in the conference. “As keynote speaker for our annual patient symposium, Scott will inspire people suffering from SD with his own story of perseverance, determination and success in spite of the communication barriers caused by spasmodic dysphonia.”

Adams spoke to the importance of resilience in his recently published book How to Fail at Almost Everything and Still Win Big: Kind of the Story of My Life. While addressing how to embrace and learn from failure in order to achieve success, Adams discusses his struggle with spasmodic dysphonia as a central theme in a lifetime of experience in overcoming adversity.

Spasmodic dysphonia impairs communication and can make it a constant struggle to get sentences out. This can affect relationships, causing people to feel isolated or to withdraw. As Adams has stated, “You don’t feel connected to the world just because you are listening. You feel connected when you know you have been heard.”

The presentation was recorded and will be uploaded to view shortly.

Bay to the Breakers Race Raises Over $3,000 for SD Research

It all started as Board Member Stephie Mendel's "wild fundraising idea" to have an NSDA team in the upcoming Bay to Breakers Race on May 17 which is the day after the NSDA Symposium. With her enthusiasm and that of the other Board members, Greater Sacramento Area Support Group Leader Jan Lant took up the cause and found eager runners in her children to represent the NSDA. More...

“I was shocked and so excited when Christie (daughter, 40's) and Matt (son-in-law) agreed to participate in the Bay to Breakers run/walk fundraiser on behalf of the NSDA. When they responded that they would do it if we could just watch our granddaughter (which was like asking kids if they want ice cream), we were overjoyed! Because the symposium is in San Francisco near home this year, they said that they welcomed the opportunity to support me and the good cause of the NSDA,” Jan shared. The race, Bay to Breakers, is the oldest consecutively run annual footrace in the world, a staple to the City by the Bay since May 1912.

From the start of Jan’s SD journey, her children have always been there for her, from driving Jan to her first botulinum toxin injection appointment to continually being supportive and understanding. Jan shared, “Now that it's been 10 years since that treatment, I am so grateful for their readiness to support me and the NSDA, which was the other part of the lifeline that connected me to others with SD, to learn about it, make the most of it and to help others." Jan, her husband, Dennis Delgado, and their children will join us at the NSDA Symposium.

For those of you who attended the first ever NSDA symposium in the Bay Area, you saw firsthand how NSDA founder, Larry Kolasa, masterfully encouraged donations from the generous attendees for Team NSDA in the Bay to Breakers Race the following day. Within fifteen minutes, over $3,000 was raised! Run/walkers, Matt and Christie Cervantes, in their NSDA t-shirts with a big, sparkly “S” on the back of one and “D” on the other (along with their darling daughter), were amazed by the outpouring and generosity of the SD community. By simply having the two participants pass the NSDA “Running for Research” hats around the room, these funds were raised for the NSDA.

Sporting their NSDA shirts and hat for awareness, along with a pink tutu and polka dot socks by Christie to blend with the crazy, colorful crowd, they left the hotel at 6:15 by charter bus for the Embarcadero Hyatt starting area. The weather was overcast, comfortable and perfect for the event. The course was packed and to run required weaving or hugging the sideline, so they did a combination of walking and running together. They also met up with friends in the race from their town along the way.

Amid the hustle and bustle, there were festive costumes of Superman, Speed Racer, Elvis sightings, giraffes, pirates and a 2015 bride and groom, to name a few that were not X-rated. Adding to the revelry were vans playing music along the way and fraternity house type parties on Hayes Street Hill, which was the steepest climb. As they entered the Golden Gate Park area, they actually spotted buffalo and llamas! Only near the Pacific “breakers” at the finish line was it cooler with the ocean breeze. They finished after 2 hours, said it went by fast, was fun and they were back at the hotel by 12:30 p.m.
Matt and Christie want to express their appreciation to the NSDA for the chance to participate in this successful fundraising event and being able to check the Bay to Breakers off their bucket list! And we thank you for your support!
