Spasmodic dysphonia: a laryngeal control disorder specific to speech.
Spasmodic dysphonia (SD) is a rare neurological disorder that emerges in middle age, is usually sporadic, and affects intrinsic laryngeal muscle control only during speech. Spasmodic bursts in particular laryngeal muscles disrupt voluntary control during vowel sounds in adductor SD and interfere with voice onset after voiceless consonants in abductor SD. Little is known about its origins; it is...

متن کاملBrainstem pathology in spasmodic dysphonia.
Spasmodic dysphonia (SD) is a primary focal dystonia of unknown pathophysiology, characterized by involuntary spasms in the laryngeal muscles during speech production. We examined two rare cases of postmortem brainstem tissue from SD patients compared to four controls. In the SD patients, small clusters of inflammation were found in the reticular formation surrounding solitary tract, spinal tri...
متن کاملDisease-specific self-efficacy in spasmodic dysphonia patients.
OBJECTIVE Self-efficacy (SE) is an optimistic self-belief that one can perform a novel task. This concept involves empowerment, self-esteem, and adaptation to a stressful situation. SE is a strong predictor of health behaviors. Our objectives were to study SE in spasmodic dysphonia (SD) and to develop a disease-specific SE-SD scale. STUDY DESIGN Prospective study. SETTING Academic hospital....
متن کاملSpasmodic Dysphonia: Evidence concerning a Neurological Cause
The term spasmodic dysphonia is a recent one, suggested by Aronson et al. (1968b), as a replacement for the term spastic dysphonia. The new term was advocated because "the term spastic is commonly used to imply disease of ... pyramidal pathways", while the neurological evidence in the Aronson research concerned the extrapyramidal system. Further, Aronson et al. observed that "the strained voice...
