King-Kopetzky syndrome
Encyclopedia
King–Kopetzky syndrome is an auditory disability which appears as clinically as a “normal” hearing threshold.
It is also known as auditory processing disorder (APD)
or auditory disability with normal hearing (ADN),
The main reported disability is difficulty in hearing speech in the presence of background noise. This is in conjunction with the finding of normal hearing test results. King–Kopetzky syndrome patients will have a worse Social Hearing Handicap index (SHHI), indicating they suffer a significant degree of speech-hearing disability.
The name for the condition was coined in honor of the individuals who first described the condition (Samuel J. Kopetzky in 1948) and who first discussed the aetiological factors behind it (P.F.King in 1954).
Some studies indicated an increased prevalence of a family history of hearing impairment in these patients. The pattern of results is suggestive that King-Kopetzky patients may be related to conditions of autosomal dominant inheritance.

Different subgroups may represent different pathogenic and aetiological factors. Thus, subcategorization provides further understanding of the basis of King–Kopetzky syndrome, and hence may guide the rehabilitative management of these patients.

Causes
It seems that somatic anxiety and situations of stress may be determinants of speech-hearing disability.Some studies indicated an increased prevalence of a family history of hearing impairment in these patients. The pattern of results is suggestive that King-Kopetzky patients may be related to conditions of autosomal dominant inheritance.
Subcategories
It was found that based on sensitized measures of auditory dysfunction and on psychological assessment, Subjects could be subdivided into seven subcategories.
1- middle ear dysfunction
2- mild cochlear pathology
3- central/medial olivocochlear efferent system (MOCS) auditory dysfunction
4- purely psychological problems
5- multiple auditory pathologies
6- combined auditory dysfunction and psychological problems
