PPM –Evaluation of the Individual with Early Onset Hearing Loss-Description and References

Description and References

Pdf Summary

This document is an evaluation of individuals with early onset hearing loss. It discusses the genetic and environmental factors that can cause deafness or hearing impairment. It emphasizes the importance of genetic evaluation and testing to identify the type of hearing loss in individuals and provides guidance on genetic counseling based on the testing results. It also highlights the prevalence of hearing loss in the United States, with 1 in every 300-500 children being deaf or hard of hearing. The document states that 60% of congenital and early childhood hearing loss is genetic, while 40% is caused by environmental factors such as congenital cytomegalovirus infection. The contribution of genes to later onset forms of hearing loss is more challenging to determine but is believed to be involved in many cases. The document emphasizes the effectiveness of early hearing intervention in facilitating speech and language development in deaf and hard of hearing children. It also provides references to additional literature on the subject, including guidelines for the clinical evaluation and diagnosis of hearing loss and resources on hereditary hearing loss and congenital cytomegalovirus infection.
