Hyperacusis Research Paper

Hyperacusis is found to be associated with both peripheral and central factors. Hyperacusis is often accompanied by a cochlear hearing loss, and this usually involves damage to cochlear hair cells and subsequent auditory nerve degeneration. However, annoyance, fear, and pain hyperacusis must involve central mechanisms. Hyperacusis is a co morbid condition of various other medical conditions that are either peripheral or central factors. Hyperacusis is found in Bell’s palsy, Ménière’s disease, perilymph fistula, superior semicircular canal dehiscence, acoustic trauma, barotrauma, noise-induced hearing loss, stapedectomy, tympanoplasty, Autism, carotid aneurysm, middle cerebral aneurysm, head injury, multiple sclerosis, migraine, epilepsy, myasthenia …show more content…

These physical examinations will enable the clinician to understand to an extent the presence of hyperacusis and its effect on daily living. The presence of a clicking or popping sound during chewing, jaw locking, and changes in the biting pattern and dental occlusion are likely to indicate the presence of temporomandibular dysfunction, which has been linked with hyperacusis. Patients with superior canal dehiscence (SCD) syndrome experience vertigo and hyperacusis to bone-conducted sounds. (Burris, Evans, & Carlson, 2010; Hilgenberg, Saldanha, Cunha, Rubo, & Conti, 2012). Laboratory Evaluation Blood tests can include a whole blood count and measures of sodium, potassium, thyroid stimulating hormone, and free thyroxine, useful in screening for infections and endocrinological diseases. Deficiencies in magnesium and Vitamin B6 levels can cause syndromes linked to neural hyperactivity. Serological tests, which measure the levels of specific antibodies in the blood, are used to diagnose diseases linked with hyperacusis, such as syphilis, herpes zoster, and Lyme disease. Imaging

2015). In Australia between nine and 12 children per 10,000 births will be born with a moderate or greater hearing loss in both ears and a further 23 children per 10,000 will acquire a hearing impairment that will require hearing aids by the age of 17 (Australian Hearing 2013). Within the Aboriginal and Torres Strait Islander communities it is estimated that 30-80% of indigenous children will suffer from some form of hearing loss. Ear disease and hearing impairments is a significant problem in developing countries and among many of the indigenous populations, especially in Australia (Burrow et al. 2009). Although middle ear disease or Otitis Media (OM), an inflammation of the middle ear, typically leads to conductive hearing loss there are rare cases leading to high frequency sensorineural hearing loss after repeated exposure (Burrow et al. 2009; American Speech-Language-Hearing Association [ASLHA]

Tests to determine the cause or complications may include an abdominal CT scan, ACTH, pituitary MRI,and bone mineral density testing. Etiology- The chance of recovering adrenal function varies per patient. Patients with Cushing’s disease had a 58% chance; and patients with adrenal Cushing’s syndrome had a 38% chance.

Because of this, VLCFA’s accumulate throughout the person’s body, particularly in their adrenal glands, blood, and myelin. Accumulation of VLCFA’s interferes with their adrenal gland’s ability to convert cholesterol into steroids, prompting deterioration of the myelin covering their nerve cells within the white matter of their brain and interfering with their nerve function. Fats that are usually produced through the breakdown of products of VLCFA’s also cannot be produced, and due to this the person’s nerve functioning is further compromised. Although this disorder was initially thought to occur only in childhood, it is now apparent that it can occur over a wide age spectrum with considerable clinical

The brainstem neurons inside of the superior olivary nuclei then fire action potentials at a rate corresponding to the difference in frequency of the binaural beat (2). In addition to the effects of binaural beats on the brainstem, electroencephalograms (EEGs) of patients listening to binaural beats have shown altered brain wave activity of the temporal and parietal lobes (2). It is through this altered neurophysiology that it has been hypothesized that binaural beats bring about changes in the memory, mood states, and perception of chronic pain in a patient
