Development of an Arabic Central Auditory Processing Remediation Program for Dyslexic Children With(C)APD

Study Overview
=================
Brief Summary
-----------------
Rehabilitation of dyslexic children with (cental) auditory processing disorder. The first group will receive the proposed program the arabic version of differential processing training program and the control group will receive the computer based auditory traing program (CBAT).

Detailed Description
-----------------
Central Auditory Processing Disorder(C)APD is defined as difficulty for children with normal hearing to listen selectively in the presence of noise, to combine information from two ears properly, to process speech when it is slightly degraded, and to integrate auditory information when it is delivered faster than the individual with (C)APD can process.( The estimated prevalence of (C)APD in the school-aged population is approximately 2 to 5 %, and the estimated prevalence of (C)APD in the older adult population is 76 %. These percentages are higher than those affected by hearing loss. Dyslexia and (C)APD are common comorbidities and since there is limited research on (C)APD within each related academic discipline. Furthermore the language, audiologiological , and cognitive nature of the disorder confirmed that a multi-disciplinary effort is needed in order to provide clinical decision and effective intervention for the (C)APD population. Hence Development of additional intervention tools for use in clinics, schools and home settings is warranted . The aim of this work is to develop a novel Arabic (C)APD remediation program ,to study the outcome of the program and to validate it's effectiveness by comparing it to the Arabic computer based auditory training(CBAT) program.
