![]() In Brazil, there is a shortage of questionnaires with methodological rigor in Brazilian–Portuguese language, intended to assist with the screening and clinical delineation of auditory processing disorders. 11, 16, 17, 18 Although questionnaires are used by 75% of educational audiologists in the United States to investigate issues related to CAPD, 19 there are disagreements about the validity of the questionnaires, degrees of sensitivity and specificity for CAPD, difficulty in reading and interpreting the questions, 10 and about not performing differential screening with other disorders, such as attention and language. Several questionnaires that investigate hearing and listening skills have been developed and/or studied in the international literature, with excellent psychometric characteristics and with great potential to detect individuals who are likely to have CAPD. The international guidelines and consensus statements on CAP 2, 3, 9, 13, 14, 15 recommend the use of questionnaires and scales to identify individuals at risk for CAPD, as they provide information about the individual’s communication deficits and the functional impact on the individual's communication, academic or work performance. In any case, CAP diagnosis has been carried out through behavioral tests aiming to assess the auditory mechanisms and electrophysiological tests to evaluate the integrity of the central auditory pathway. Lately, there has been much controversy about the recognition of CAPD as a single clinical entity in the United States, especially with regards to overlapping clinical manifestations with other disorders, questions about whether it is primarily a top-down or bottom-up sensory-neural deficit and an inability of the scientific community to reach a consensus on diagnosis and intervention planning. The behaviors observed in children with CAPD include hearing, school, and social difficulties. The American Speech-Language-Hearing Association (ASHA) establishes that CAPD refers to difficulties in processing auditory information in the central nervous system and the neurobiological activity that underlies this process that generates electrophysiological auditory potentials. 1, 2Ĭentral Auditory Processing Disorder (CAPD) has been recognized as a clinical entity since 2005, 2 which means the condition has distinct and finite features with clearly referenced diagnostic criteria. ![]() ![]() Central Auditory Processing (CAP) refers to the functions of the Central Auditory Nervous System (CANS) which parses auditory information, and involves sound stimuli analysis and interpretation.
