| Abstract | OBJECTIVE: Several studies have demonstrated that adult subjects with Down's syndrome (DS) and hearing impairments show significantly delayed latencies in auditory late potentials (ALPs). The aim of this study was to investigate whether the differences were still present in ALPs in an adult DS population with normal hearing, taking into consideration sex, handedness, and head size. STUDY DESIGN: Prospective study. SETTING: Audiology unit of the hospital Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan, Italy. PATIENTS: Sixteen normal-hearing adult DS subjects referred to the health monitoring program for DS patients of Vivi Down Onlus Association in Milan, Italy (7 male subjects with a mean age of 26 ± 7.74 yr and 9 female subjects with a mean age of 28 ± 8.63 yr) and 16 controls (7 male subjects with a mean age of 26 ± 7.74 yr and 9 female subjects with a mean age of 28 ± 8.86 yr) matched for sex, age, and handedness. MAIN OUTCOME MEASURE: The 2 negative peaks, N1 and N2, and the 2 positive peaks, P1 and P2, of ALP. RESULTS: ALP N1 and P2 components were well defined in all subjects. The P1 and N2 components were less evident than the others. There were significant delayed latencies in the DS group with respect to the control subjects for P1, N1, P2, and N2 components. CONCLUSION: Our study demonstrated that ALP longer latencies are present in adult DS participants even when they have a normal hearing threshold, regardless of handedness and head size. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
