Auditory Processing Disorder (APD) are defects of the auditory sense, which result from abnormalities in the functioning of the auditory path at the level of the central nervous system from the center of the Cochlea to the auditory cortex. This is a problem that 2-3% of children, aged 7-14 suffer from in Poland.The aim of this paper is to establish a spectrum of the most common symptoms as well as to determine the most common age range of the children that have been diagnosed.A retrospective analysis was conducted, based on the medical documentation of patients diagnosed and treated in the audiological clinic. The examined group consisted of 215 children ages 6 to 18. The inclusion criteria were as follows: normal peripheral hearing and an IQ indicator of at least 85. Data was analyzed with the use of STATISTICA 9.1 program.The highest number of children were admitted with problems connected to writing (78,15%), reading (69,77%), and concentrating (60,93%). The most common symptomsamong patients who have been diagnosed with APD)were as follows: late speech development (96%), speech defects (91,4%), problems with learning a language (91,67%). The most numerous group represented were patients aged 10 to 12 (40,93%). The accuracy of the initial diagnosis was the highest in the 6 to 7 age group (96,15%).The results of this paper speak for the necessity of increasing APD awareness among people close to a child as the problems that emerge are common and a lot of the diagnoses late.
