Question Title: Spasmodic dysphonia vs laryngeal dysfunction?Forum: Neurology Forum
| ||||
I had a friend ask me today if I'd ever had a diagnosis of spasmodic dysphonia suggested. Since I had never seen the term before, I checked the web for information after I answered him. What I saw made me curious. A lot of what I read seems very similar to what I've been told about laryngeal dysfunction, which it has been suggested I do have. Especially since there *has* been a determination that SD is neurologically based, I am curious as to whether this may in fact, be a more accurate diagnosis. We know that a lot of my speech and language (and other) difficulties are neurologically based, but as for specifics we have very little. Partly because we didn't know what we were looking for, so were refused when we requested a neurological assessment.ANyways, I was wondering if someone could compare and contrast laryngeal dysfunction and Spasmodic dysfunction for me? These are two very different terms , laryngeal dysfunction is not a diagnosis or a specific disease, it simply means "something wrong with the function of the larynx " This can be due to any underlying cause, stroke, ALS, hysteria,local inflammation,tumor or spasmodic dysphonia. Spasmodic dysphonia ion the other hand is a specific neurologically mediated disease in which the brain causes spasm of muscles in the larynx, it responds well to local injections of botulinum toxin into the muscles. So in summary one of your terms is a description of a symptom, the other is a disease label.
