SD is, in most cases, a form of dystonia, a moment disorder characterized by involuntary, uncontrolled muscle spasms.
Whereas some dystonias affect the eyelids, neck or arm muscles, SD involves spasms of the vocal cords.
Doctors may refer patients for speech therapy or psychotherapy. When these treatments fail, patients may seek help through biofeedback, acupuncture or electroconvulsive therapy, for example. Perhaps physicians can’t be faulted for their misdiagnoses and inappropriate prescriptions. Most doctors have never encountered SD. And in the absence of any invisible pathology, inflamed throat, vocal-cord polyps or nodules, the doctors hears only a uniquely tight voice and strain or psychological stress.
The mystery is compounded further because not all SD patients sound alike. Some voices break on almost every syllable, while others sound gravelly. In fact, some people with SD can occasionally speak normally.
Anatomy of an illness
To speak, we exhale breath through the windpipe, forcing air between the two normally closed vocal cords. The vocal cords vibrate, producing sound. When someone with adductor SD tries to talk, erratic muscle spasms lock the vocal cords together, cutting off the breath stream. As a result, her voice sounds choked. In the case of abductor SD, the vocal cords remain open and can’t vibrate properly.
There is no conclusive evidence linking excessive vocal use, smoking, air pollution or other environmental factors with SD, either.
Laryngitis is not SD. resting your voice and drinking hot tea with honey helps to alleviate laryngitis, but not SD.
And SD is not the same as stuttering, Like SD victims, stutterers may lock their vocal cords during speech. But, unlike SD, stuttering unusually begins during early childhood, and is much more prevalent among boys than girls. More important, thought, about 80 % of those who stutter at one time or another spontaneously recover from it. Spontaneous recovery from SD is exceedingly rare.
The people with SD
Experts can’t pinpoint precisely how many people suffer from SD, partly because so many SD patients are misdiagnosed. Many SD patients who attributed a strained voice to “nerves” never seek to medical attention at all. And since SD patients often consult more than one specialist it is difficult to maintain an accurate count. We just don’t know it we are all treating different case or the same people.
Researchers, however, have developed a demographic profile of SD patients. It is 1 ½
more common in women than in men. The average age of onset is about 35; and most patients are between 30 & 60.
After reviewing many patients’ family trees, experts believe SD may have a genetic link. In fact, he and other leading SD researchers important to get the patient’s family history provide genetic counseling, so SD patients can learn what the potential is to pass this on to their offspring.
Whoever they are, SD patients are likely to suffer the same frustrations. Perhaps ordinary situations best epitomize the experience of SD. Just about everything that most people do without thinking become a potential snag; asking for help in a store, ordering a meal in a restaurant, calling for a haircut appointment, introducing yourself.
Aside from these everyday problems, SD can also disrupt your social life.
Gatherings cause anxiety between SD sufferers and their spouses.
