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.
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.
A conductive hearing loss along with middle ear disease is most commonly seen in patients with Pfeiffer syndrome; although, there have been reports of mixed hearing loss as well. The hearing loss is most typically caused by stenosis or atresia of the auditory canal, middle ear hypoplasia and ossicular hypoplasia (Vallino-Napoli, 1996).
Selective hearing is not known to be a disorder of the physiological or psychological aspect. Under the World Health Organization (WHO), a hearing disorder happens when there is a complete loss of hearing in the ears. It means the loss of the ability to hear. Technically speaking, selective hearing is not "deafness" to a certain sound message ...
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]
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 ...
CHARGE syndrome (formerly known as CHARGE association) is a rare syndrome caused by a genetic disorder.First described in 1979, the acronym "CHARGE" came into use for newborn children with the congenital features of coloboma of the eye, heart defects, atresia of the nasal choanae, restricted growth or development, genital or urinary abnormalities, and ear abnormalities and deafness. [1]
Newborn children with no hearing on one side but one normal ear could still have problems. [7] Speech development could be delayed and difficulties to concentrate in school are common. More children with unilateral hearing loss have to repeat classes than their peers. Taking part in social activities could be a problem.
