Auditory Processing Disorder

Auditory processing disorder (APD) means that something is adversely affecting the processing or interpretation of information. Children with APD are not able to recognize subtle differences between sounds in words, even though the sounds themselves are loud and clear. If an individual's auditory processing is functioning well but there is no understanding of the sounds that are heard, the individual may have an APD.
The process of human communication is related with the information imbibed from the outside world through the different senses which we have like hearing; seeing etc.this imbibed information is interpreted in a meaningful way. Attention and memory are the prime requisites for the perception of this information. it is still not clear how these processes work and how these help in the processes of communication.
Many children with APD have a family history of auditory difficulties or partial deafness. In addition, there are some developmental issues that have been shown to have a relationship to APD. The exact cause of APD is still unknown. In children, auditory processing difficulty may be associated with conditions such as:
    • Dyslexia,
    • Attention Deficit Disorder (ADD),
    • Autism,
    • Neurological diseases/disorders
    • Autism Spectrum Disorder,
    • Specific Language Impairment,
    • Pervasive Development Disorder,
    • Or Developmental Delay. Sometimes this term has been mis-applied to children who have no hearing or language disorder but have challenges in learning.
    • Neuro morphological disorder (irregularities in cells in the left hemisphere or auditory area of the brain)
In some children with APD there may be tiny differences in the way that neurons of the brain cells are joined together, or how they send messages to each other. This thus causes hard for sounds to be passed on to the areas of the brain that aid in the understanding of language. One possible reason is that such brain cell differences may cause...
