Spasmodic dysphonia, also known as laryngeal dystonia, is a disorder in which the muscles that generate a person's voice go into periods of spasm. [1] [2] This results in breaks or interruptions in the voice, often every few sentences, which can make a person difficult to understand. [1]

What causes spasmodic dysphonia? The disorder is a neurological problem, the Cleveland Clinic says, that is believed to start in the basal ganglia—a part of the brain that coordinates muscle ...
MTD can be distinguished for another similar dysphonia, adductor spasmodic dysphonia, by differences in voice characteristics. [12] In MTD, all vocal tasks (vowels, singing, etc) are difficult for the patient while in adductor spasmodic dysphonia, some vocal tasks are difficult while others are unaffected. [12]
Voice disorders can be divided into two broad categories: organic and functional. [9] The distinction between these broad classes stems from their cause, whereby organic dysphonia results from some sort of physiological change in one of the subsystems of speech (for voice, usually respiration, laryngeal anatomy, and/or other parts of the vocal tract are affected).
Laryngospasm is an uncontrolled or involuntary muscular contraction of the vocal folds. [1] It may be triggered when the vocal cords or the area of the trachea below the vocal folds detects the entry of water, mucus, blood, or other substance.
Spasmodic dysphonia is caused by strained vocal cord movement, which results in awkward voice problems, such as jerkiness or quavering. [3] If nodules or polyps are present, and are large, surgery may be the appropriate choice for removal. Surgery is not recommended for children, however.
Spasmodic dysphonia: A dystonia of the vocal cords. The complications surrounding this form of dystonia are speech related and can cause symptoms such as speech that wavers, speech that sounds like a whisper, or speech that is hesitant.
