These conditions result from continuous damage to the laryngeal nerves [4] [3] and often lead to vocal disability. [6] Recurrent laryngeal nerve damage is the most common cause of vocal fold paresis. [4] The RLN is responsible for motor input to the vocal folds. [4] Physicians may also use the term recurrent laryngeal nerve paralysis. [19]
Recurrent laryngeal nerve avulsion is a more drastic removal of sections of the nerve, [45] and has positive outcomes of 80% at three years. [41] SLAD-R is effective specifically for adductor spasmodic dysphonia, for which it has shown good outcomes in about 80% of people at 8 years. [39] Thyroplasty changes the position or length of the vocal ...
Anosmia is the inability to perceive odor, or in other words a lack of functioning olfaction.Many patients may experience unilateral or bilateral anosmia. A temporary loss of smell can be caused by a blocked nose or infection. In contrast, a permanent loss of smell may be caused by death of olfactory receptor neurons in the nose or by brain injury in which there is damage to the
Common clinical features of ataxic dysarthria include abnormalities in speech modulation, rate of speech, explosive or scanning speech, slurred speech, irregular stress patterns, and vocalic and consonantal misarticulations. [13] [14] Ataxic dysarthria is associated with damage to the left cerebellar hemisphere in right-handed patients. [15]
For many children and adolescents, this can present as issues with academics. [4] Speech disorders affect roughly 11.5% of the US population, and 5% of the primary school population. [5] Speech is a complex process that requires precise timing, nerve and muscle control, and as a result is susceptible to impairments. A person who has a stroke ...
Speech disorders may develop from nerve injury to the brain, muscular paralysis, structural defects, hysteria, or mental retardation. Speech processor Part of a cochlear implant that converts speech sounds into electrical impulses to stimulate the auditory nerve, allowing an individual to understand sound and speech.

Because of this, ataxia can be caused by damage to or issues within this brain structure; "but poor sensation in the feet, inner-ear problems or vision issues can lead to similar problems with ...
Speaking is an act dependent on thought and timed execution of airflow and oral motor / oral placement of the lips, tongue, and jaw that can be disrupted by weakness in oral musculature or an inability to execute the motor movements needed for specific speech sound production (apraxia of speech or developmental verbal dyspraxia).
