A benign neurological voice disorder caused by [intlink id=”267″ type=”post”]laryngeal dystonia[/intlink]. Atypical cases of SD may be challenging to diagnose, even by clinicians with some experience with the disorder. Examples of reasons that this may be so: In the atypical case, contrary to what is usually seen, singing may be more affected than talking; falsetto/head voice may be more affected than chest voice, and so forth. There may also be no [intlink id=”432″ type=”post”]phonatory arrests[/intlink] in the less common [intlink id=”575″ type=”post”]tonic variant spasmodic dysphonia[/intlink].
