Vitamin D deficiency--a new cause of cochlear deafness.

Brookes GB.

Abstract

Ten patients are reported with bilateral cochlear deafness which was associated with vitamin D deficiency. The features of these cases are discussed following an overview of the clinical aspects and diagnosis of vitamin D deficiency. The most likely pathogenesis is localized demineralization of the cochlea resulting in secondary morphological changes. Replacement therapy resulted in unilateral hearing improvement in two of the four patients in whom the response to treatment could be assessed. This suggests a previously unrecognized causal correlation between vitamin D deficiency and cochlear deafness. Impaired vitamin D activity may be important in the aetiology of otosclerosis, presbyacusis and the deafness associated with chronic renal failure. Vitamin D deficiency should be considered in the differential diagnosis of unexplained bilateral cochlear deafness. It is important, as this 'new' metabolic type of sensorineural deafness may be reversible, and may also lead to the diagnosis of early osteomalacia before more serious generalized skeletal symptoms can occur.

Introducing the worlds first effective
Hearing Loss Treatment!

The Hearing Fix

The Hearing Fix is a revolutionary hearing loss treatment scientifically engineered to help restore ones natural hearing abilities. Our new product can help improve hearing problems in those suffering from almost all types of hearing impairment including: Sensorineural hearing loss (nerve damage), Sudden hearing loss, Presbycusis (age-related), Conductive, Noise Induced and high frequency hearing loss.

he Hearing Fix works to improve hearing loss symptoms through three distinct paths:

The Hearing fix is designed to facilitate improved nerve communication between the ears and the brain. In simple terms, it greatly improves how the nerves in the ear transfer sound.

The Hearing Fix helps stop dangerous molecules that cause hearing damage to the inner ear, even after exposure to loud noise.

The Hearing Fix provides the body with many of the absolutely essential compounds that are necessary for proper hearing function.

Hearing Loss appears to be prevented and treated with vitamin D

By getting stronger ear bones

Bought my 98 year-old father-in-law to an audiologist yesterday (Oct 19, 2010) to try out some new hearing aids, and I realized that his hearing had improved recently. He has been taking 10,000 IU of vitamin D and co-factors by Jarrow of Calcium, Magnesium, vitamin K2, etc for the past 9 months. Wondered if there was a correlation.

Using Google, I found that hearing-loss "vitamin d” resulted in 270,000 hits

http://www.naturalnews.com/026834_hearing_loss_magnesium_Vitamin_D.html Prevent and Even Reverse Age-Related Hearing Loss with Good Nutrition Aug 2009, by Kerri Knox clip: When vitamin D deficiency causes osteopenia in the tiny bones of the ears, this can lead to hearing loss and even deafness. Strikingly, correcting the vitamin D deficiency often corrects the hearing loss and even the deafness in these specific cases.
She also describes Magnesium "Magnesium treatment has been repeatedly shown link building service to reduce the incidence of both temporary and permanent noise-induced hearing loss.”

http://www.innvista.com/health/ailments/earail/hearnutr.htm “Hearing and Nutrition” talks about many vitamins and minerals, and has this to day about vitamin D. “As far as hearing is concerned, a deficiency in this vitamin has serious consequences and has been associated with otosclerosis (abnormal bone growth in the middle ear), unexplained and bilateral cochlear deafness, presbycusis, and sensorineural hearing loss. Researchers had to conclude that vitamin D deficiency is likely one of the causes and supplementation should be considered in persons with hearing loss. Vitamin D can be inhibited if there is also a magnesium deficiency. If there is a magnesium deficiency, this will also affect calcium intakes. As you can see, not just one nutrient can be isolated as being a cause or cure of something. “

http://findarticles.com/p/articles/mi_m0ISW/is_282/ai_n19170311/ Take control of your hearing loss before it's too late. Extensive article of Jan 2007 in Townsend Letter for Doctors, written by Dr. Jonathan V. Wright. Clip – – “Years ago, the Journal of the American Medical Association (JAMA) published a brief article reporting that vitamin D supplementation slowed hearing loss. Since then, research findings have been conflicting, some reporting significant vitamin D deficiency, (1-2) and others not. (3) I've advised individuals with age-related hearing loss to use at least 3,000 to 4,000 IU daily, but the results have been mixed.”

http://www.ehow.com/how_2122698_reverse-hearing-loss-naturally.html How to Reverse Hearing Loss Naturally: clip – – Get enough vitamin D in your diet in order to reverse hearing loss naturally. If you don't have enough vitamin D in your system, this causes insufficient amounts of calcium in the fluid of the inner ear. If you don't have enough calcium, the small bones of the inner ear become spongy. This spongy state interferes with sound transmission.

http://www.reeis.usda.gov/web/crisprojectpages/189531.html 2003 study at the Univ. of Geogia: VITAMIN D DEFICIENCY AND AUDITORY FUNCTION OF GENETICALLY DISORDERED MICE . Interesting study of vitamin D and Calcium for mice, pregnant mice, and off-spring.

Hypothesis: Lack of vitamin D is one of the causes of hearing loss with age as well as osteoporosis

One of the reasons for deafness with age is the lack of vitamin D weakening of all bones, including those in the ear. Unless an older person is getting many hours of sunshine daily or taking vitamin D supplements the vitamin D levels are known to greatly decline. The skin produces less than 1/3 as much vitamin D per minute for an older person due to lack of pre-vitamin D in the skin. So the lack of vitamin D which weakens the bones and causes hip fractures, etc also weakens the bones in the ear which are vital for hearing.

It will be interesting to find out of other populations low on vitamin D also have problems with hearing loss
From Criteria for vitamin D deficiency in VitaminDWiki

1. Overweight
2. Age -
3. Smoking - ties up vitamin D
4. Alcohol
5. Stress
6. Medical problems which reduce vitamin D - MS, kidney, gut, liver, kidney...
7. Dark skin -
8. Taking a drug which reduces vitamin D
9. Live far from equator

But, one report shows people with dark skin have LESS hearing loss with age

Clip - The prevalence of self-reported hearing impairment not only varies by race but also by ethnicity. For example, the 1999 National Health Interview Survey (Pleis & Coles, 2003) found that adults from Asian and African decent were less likely to experience hearing problems (7.8% and 7.4% respectively) than Whites or Native Americans (17.2 and 20.1, respectively). Whereas 15% of non-Hispanic White adults reported some form of hearing difficulty, 6% of non-Hispanic Black adults and 6% of Hispan
White adults reported hearing problems.
