Auditory processing disorder (APD) is a neurodevelopmental disorder affecting the way the brain processes sounds. [2] Individuals with APD usually have normal structure and function of the ear, but cannot process the information they hear in the same way as others do, which leads to difficulties in recognizing and interpreting sounds, especially the sounds composing speech.
A speech sound disorder (SSD) is a speech disorder affecting the ability to pronounce speech sounds, which includes speech articulation disorders and phonemic disorders, the latter referring to some sounds not being produced or used correctly. The term "protracted phonological development" is sometimes preferred when describing children's ...
Research has shown spatial hearing loss to be a leading cause of central auditory processing disorder (CAPD) in children. Children with spatial hearing loss commonly present with difficulties understanding speech in the classroom. [1] Spatial hearing loss is found in most people over 70 years of age, and can sometimes be independent of other ...
Charlie was born deaf with a genetic disorder called Usher syndrome that will eventually cause vision loss as well. "Ultimately it results in progressive hearing loss. In some kids, like in ...
Movement disorder that can involve excessive eye blinking (blepharospasm) with involuntary movements of the jaw muscles, lips, and tongue (oromandibular dystonia). Ménière's disease Inner ear disorder that can affect both hearing and balance. It can cause episodes of vertigo, hearing loss, tinnitus, and the sensation of fullness in the ear.
Another source has estimated that communication disorders—a larger category, which also includes hearing disorders—affect one of every 10 people in the United States. [ 13 ] ASHA has cited that 24.1% of children in school in the fall of 2003 received services for speech or language disorders—this amounts to a total of 1,460,583 children ...
The hearing loss is generally bilateral with a conductive loss of about 50–70 dB. Even in cases with normal auricles and open external auditory canals, the ossicular chain is often malformed. [41] Attempts to surgically reconstruct the external auditory canal and improve hearing in children with TCS have not yielded positive results. [42]
Understanding these disorders and the areas of the brain affected in each case is key in conducting further studies of dysprosody. Scientists are continuing to study these patients in the hope of creating more concrete connections between areas of brain damage and prosodic abnormalities, which will hopefully someday lead to a full understanding ...
