Deafness

Common Name(s)

Deafness, Hearing loss

Hearing loss is considered to be anything from slight to profound impairment in the ability of a person to detect frequencies and intensities of sound. It can be acquired during life or present at birth, and it can also be inherited. Hearing loss can occur in one or both ears, and affect different areas of the ears. There are two main types of hearing loss; for more information see conductive hearing loss or sensorineural hearing loss. Deafness is the most profound form of hearing loss, where an individual can hear very little. In children, deafness is defined in children whose hearing loss is is greater than 90 dB, but hearing loss can also occur with age. Symptoms of hearing loss or deafness include delayed development of speech or unclear speech, use of high volume on electronic viewing devices, and consistent need to ask for repitition in conversation. Treatment for hearing loss may include hearing aides or cochlear implants to improve hearing ability.

This organization was started by a small group of parents whose lives have been affected in some way by a rare disorder. Our gift, in honor of our children, was to start this site, so we can help families and to raise awareness of these rare disorders. If your child has been diagnosed with Zellweger syndrome, a peroxisomal disorder or another rare disorder, we are here to help you. You are not alone! Our mission is to promote, advance, and improve awareness of Zellweger syndrome and other peroxisomal disorders, to assist, support, and aid, financially or otherwise, individuals and families affected by Zellweger syndrome. We will help you learn more about these disorders. We will provide emotional support, and we can help you to create a journal site for your child so that family and friends can be kept up to date on your child. We will pray with you and for you as you journey through life with your special angel. We know this is a hard time for you; you want answers, informa
