These spasms make it difficult for the vocal folds to vibrate and produce voice. Words are often cut off or are difficult to start because of the muscle spasms. Therefore, speech may be choppy but differs from stuttering. The voice of an individual with adductor spasmodic dysphonia is commonly described as strained or strangled and full of effort.
Voice disorders [1] are medical conditions involving abnormal pitch, loudness or quality of the sound produced by the larynx and thereby affecting speech production. These include: These include: Vocal fold nodules
Essential tremor (ET), also called benign tremor, familial tremor, and idiopathic tremor, is a medical condition characterized by involuntary rhythmic contractions and relaxations (oscillations or twitching movements) of certain muscle groups in one or more body parts of unknown cause. [6]
Can be caused by Chlorpromazine. Oromandibular dystonia: muscles of the jaw and muscles of tongue: Causes distortions of the mouth and tongue. Spasmodic dysphonia/Laryngeal dystonia muscles of larynx: Causes the voice to sound broken, become hoarse, sometimes reducing it to a whisper. Focal hand dystonia (also known as musician's or writer's ...
Tremors are symmetric about a midpoint within the movement, and both portions of the movement occur at the same speed. Unlike the other hyperkinetic movements, tremors lack both the jerking associated movements and posturing. [4] Essential tremor (ET), also known as benign essential tremor, or familial tremor, is the most common movement ...
The KE family is a medical name designated for a British family, about half of whom exhibit a severe speech disorder called developmental verbal dyspraxia. [1] It is the first family with speech disorder to be investigated using genetic analyses, by which the speech impairment is discovered to be due to genetic mutation, and from which the gene FOXP2, often dubbed the "language gene", was ...
Tremor can also be caused by lack of sleep, lack of vitamins, or increased stress. [11] [12] Deficiencies of magnesium and thiamine [13] have also been known to cause tremor or shaking, which resolves when the deficiency is corrected. [14] Tremors in animals can also be caused by some spider bites, e.g. the redback spider of Australia. [15]
A number of other causes for losing one's voice exist, and treatment is generally by resting the voice and treating the underlying cause. [2] If the cause is misuse or overuse of the voice, drinking plenty of water may alleviate the problems. [2] It appears to occur more commonly in females and the elderly. [4]
