Auditory Processing Disorders in children suspected of Learning Disabilities--a need for screening?

Int J Pediatr Otorhinolaryngol. 2009 Jul;73(7):1029-34. doi: 10.1016/j.ijporl.2009.04.004. Epub 2009 May 7.


Aim: The current study aims to assess: (a) the prevalence of auditory processing in a population of children reporting learning difficulties, (b) the correlation of APD diagnosis with age, the intelligence coefficient (IQ) and with the presence of a specific learning disability such as dyslexia and (c) to evaluate the reliability of each auditory processing test used in this study in identifying APD.

Method: We evaluated one hundred and twenty-seven consecutive children referred to the academic tertiary LD Clinic of the Psychiatric Department by means of a psychoacoustic mainly non-verbal test battery.

Results: APD was found to be present in 43.3% and co-existing with developmental dyslexia in 25% of cases. The diagnosis of APD correlated with age in that children with APD were younger by 2 years than those without a diagnosis of APD. The diagnosis of APD did not correlate with IQ or with the diagnosis of dyslexia.

Interpretation: High prevalence of APD in the targeted group of children suspected of Learning Disabilities sets the grounds for a possible benefit in screening for the disorder.
