The person's voice may also sound strained or they may be nearly unable to speak. [2] Onset is often gradual and the condition is lifelong. [1] The cause is unknown. [1] Risk factors may include family history. [1] Triggers may include an upper respiratory infection, injury to the larynx, overuse of the voice, and psychological stress. [1]
Children with childhood dementias suffer severe sleep disturbances, movement disorders (e.g. muscle spasms, tremors), deterioration of communication skills, loss of vision and hearing, mood disorders, psychosis (including hallucinations and delusions) and incontinence. [3] This situation can cause many emotional changes for parents and children.
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: Vocal fold nodules; Vocal fold cysts; Vocal cord paresis; Reinke's edema; Spasmodic dysphonia; Foreign accent syndrome; Bogart–Bacall syndrome; Laryngeal ...
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).
Voice therapy is commonly used in the treatment of MTD. [7] The goal of voice therapy is to encourage proper vocal used and decrease the tension of the laryngeal muscles. [ 15 ] Examples of voice therapy include voice exercises to help increase glottic closure, vocal hygiene, manual laryngeal therapy, respiratory exercises, nasal exercises and ...
Hereditary causes have also been suggested, as many times children of individuals with speech disorders will develop them as well. [15] 20-40% individuals with a family history of a specific language impairment are likely to be diagnosed, whereas only 4% of the population overall is likely to be diagnosed. [16] There are also language disorders ...
Vocal cord paresis, also known as recurrent laryngeal nerve paralysis or vocal fold paralysis, is an injury to one or both recurrent laryngeal nerves (RLNs), which control all intrinsic muscles of the larynx except for the cricothyroid muscle. The RLN is important for speaking, breathing and swallowing.
The low pitch voice is a direct result of increased fluid in the Reinke's space, which vibrates at a lower frequency than normal (females <130 Hz; males <110 Hz). [12] Hoarseness is a common problem of many laryngeal diseases, such as laryngitis. It is described as a harsh and breathy tone of voice.
