This research aims to do the following: Describe the nature of hearing loss and its effect on families Improve structure and quality control for programs monitoring the status of children with hearing loss Remove barriers to obtaining effective services Cytomegalovirus & Hearing Loss The studies below concern the long-term hearing loss risk of children born with cytomegalovirus. Some children with congenital cytomegalovirus (CMV) infection may have hearing or vision loss, or other health problems. Cytomegalovirus can be transmitted to an unborn baby during a woman's pregnancy. Some babies with congenital cytomegalovirus have hearing loss at birth in addition to other conditions. While some babies may have normal hearing initially, some will develop hearing loss later.

Hearing Loss Treatment and Intervention Services | CDC
No single treatment or intervention is the answer for every child or family. Good intervention plans will include close monitoring, follow-ups and any changes needed along the way. There are many different options for children with hearing loss and their families. Some of the treatment and intervention options include: Working with a professional (or team) who can help a child and family learn to communicate. Getting a hearing device, such as a hearing aid. Joining support groups. Taking advantage of other resources available to children with a hearing loss and their families. Early Intervention and Special Education Early Intervention (0-3 years) Hearing loss can affect a child's ability to develop speech, language, and social skills. The earlier a child who is deaf or hard-of-hearing starts getting services, the more likely the child's speech, language, and social skills will reach their full potential. Early intervention program services help young children with hearing loss learn language skills and other important skills.
Genetic Sensorineural Hearing Loss: Practice Essentials, Pathophysiology, Epidemiology
In addition to ancestry and race, the proportions of hereditary versus acquired and syndromic versus nonsyndromic hearing losses across populations is highly variable and is heavily influenced by multiple factors, some likely not yet identified, including drift of populations, frequency of consanguinity, and health status. Estimating the prevalence of hereditary hearing loss in populations across the world is very difficult because access to health care, poor health conditions, and a low level of awareness of hearing loss is compounded by a higher frequency of complicating risk factors such as neonatal distress, prematurity, high fever, otitis media, meningitis, ototoxic medications, and illnesses such as rubella. [ 9] An estimated 30, 000 infants are born with sensorineural hearing loss each year in China, which has a population of about 1. 3 billion, but the percentage of these hearing losses attributable to heredity is not known. [ 10] Saunders et al demonstrated a prevalence of significant hearing loss of 18% in a group of school-aged children in rural Nicaragua with a familial history of hearing loss in 24% of the children with hearing loss.

Hearing Loss in Children
Conductive hearing loss may not be permanent, and can often be treated with medicine or surgery. Sensorineural: This is a problem with the inner ear, especially the vestibular cochlear nerve. Causes of sensorineural hearing loss include: Abnormal development in the womb. Injury from certain diseases and infections. Certain medicines. Heredity. Fluid backup. Tumors. Aging. Overexposure to loud noise (which kills the hair cells). This type of hearing loss is permanent. In many cases, sensorineural hearing loss can be treated with hearing aids. Mixed: This is a combination of conductive and sensorineural hearing loss. What are the risk factors for hearing loss? A risk factor is a condition that increases the chances of getting a disorder. Risk factors for hearing loss in children include: Otitis media (ear infections, the most common cause of hearing loss in young children). Craniofacial abnormalities (the head, face, or ears are shaped differently). Family history of hearing loss. Exposure to infection in the womb.
Determining How Many Children Have Hearing Loss By studying the number of children diagnosed with hearing loss over time, we can find out if the number is rising, dropping, or staying the same. We can compare the number of children with hearing loss in different groups of people. This information can help us look for causes of hearing loss and help communities plan for services. We do not know exactly how many children have hearing loss. CDC data have shown that approximately 1 to 3 per 1, 000 children have hearing loss. Other studies have shown rates from 2 to 5 per 1, 000 children. Data chart of prevalence studies Following are activities that CDC conducts or funds in order to learn more about the number of children with hearing loss: Metropolitan Atlanta Developmental Disabilities Surveillance Program (MADDSP) CDC tracks the number of eight-year-old children in a five-county area in metropolitan Atlanta, Georgia who have moderate to profound hearing loss in both ears. For this project, we define moderate to profound hearing loss as a 40 dB or greater loss in the better ear, without the use of hearing aids.

Approximately 50% of the hearing loss caused is genetic, 25% is acquired and 25% caused due to an unknown cause. But here are some following common cause – Birth complications Premature birth. A nervous system or brain disorder. The mother had an infection during pregnancy. Maternal diabetes. Drug or alcohol abuse by the mother or smoking during pregnancy. Inner ear abnormality such as Mondini dysplasia with variable inheritance patterns results in 20% of the Congenital sensorineural deafness and the remaining do not have distinguishing features. It depends on 2 factors: Genetic factors (Inherited congenital deafness) Hearing loss from the genetic defect can be present at the time of birth or develop later in life. It causes more than 50% of the hearing loss. Non-syndromic deafness- About 80% of genetic disorder is non- syndromic. It has two types, Autosomal dominant (DFNA) and Autosomal recessive (DFNB). Autosomal Recessive hearing loss: It occurs when a child receives a hearing loss gene from each parent.
Understanding your options & technologies. After identifying your child's hearing loss, you will be introduced to an expert team who will answer all your questions and assist you in the process of deciding which management option is best for your child. While hearing aids are usually a great solution for children with mild-to-moderate hearing loss, cochlear implants are the leading option for those with severe-to-profound hearing loss. 2 Typically, children who show signs of hearing loss will be fitted with hearing aids first. Your team of hearing care professionals will keep a close eye on how your child performs with these hearing aids, and will determine if they are a candidate for a CI. How to hear better in challenging environments. Hearing with two ears dramatically helps children with spatial orientation, making it easier to sense which direction sounds—such as the honk of an oncoming car or a friend calling out on the playground—are coming from. Two-ear hearing also helps children hear speech better in noisy situations, like during playtime or lunch in the cafeteria.
It's for this reason that the most complete hearing solutions enable the use of both ears. This could be cochlear implants on both ears or an implant on one ear and a compatible hearing aid on the other. With Phonak and Advanced Bionics, you'll benefit from technology that goes beyond other options. The integrated technologies in our hearing devices "talk" to each other via a wireless signal that ensures your child is hearing as much of their environment as possible. 1.

Research shows that children who are born deaf or acquire hearing loss very early in life—and who receive appropriate interventions within six months of age— are at par with their hearing peers in terms of language development by the time they are 5 years old. 1
