The following are three case studies with different reasons for cortical deafness. A case published in 2001 describes the patient as 20-year-old man referred for cochlear implants because of bilateral deafness following a motorcycle accident two years earlier. [2] His CT shows hemorrhagic lesions involving both internal capsules. He was ...
Auditory processing disorder (APD), rarely known as King-Kopetzky syndrome, 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 ...
In one case study, each of the three sound types (music, environmental sounds, speech) was also shown to recover independently (Mendez and Geehan, 1988-case 2 [22]). It is yet unclear whether general auditory agnosia is a combination of milder auditory disorders, or whether the source of this disorder is at an earlier auditory processing stage.
Hypoacusis is defined as impairment in hearing or deafness. It was the most common of the five etiologies in the case studies reviewed by Evers and Ellgers. [3] According to Sanchez et al. 2011, there have been suggestions that pontine lesions could alter the central auditory system's function, causing hypoacusis and musical hallucinations. [8] [9]
Charcot–Marie–Tooth disease [3] an inherited neurological disorder with delayed onset that can affect the ears as well as other organs. The hearing loss in this condition is often ANSD (auditory neuropathy spectrum disorder) a neural cause of hearing loss. Muckle–Wells syndrome, a rare inherited autoinflammatory disorder, can lead to ...
Fluid accumulation is the most common cause of conductive hearing loss in the middle ear, especially in children. [3] Major causes are ear infections or conditions that block the eustachian tube, such as allergies or tumors. [3]
Some people with this disorder report that there are specific sounds which can trigger their seizures. But most people do not have a known trigger. [4] People with ADPEAF may have different kinds of seizures, but partial seizures are often the most common. [6] The frequency of seizures can vary greatly from person-to-person. [5]
Patients with auditory neuropathy spectrum disorders have to date never been shown to have normal middle ear muscle reflexes at 95 dB HL or less despite having normal otoacoustic emissions. [ 5 ] Auditory neuropathy can occur spontaneously, or in combination with diseases like Charcot-Marie-Tooth disease and Friedreich's ataxia .
