Auditory Processing Disorder in Children (page 2)

How is suspected auditory processing difficulty diagnosed in children?

You, a teacher, or a day care provider may be the first person to notice symptoms of auditory processing difficulty in your child. So talking to your child's teacher about school or preschool performance is a good idea. Many health professionals can also diagnose APD in your child. There may need to be ongoing observation with the professionals involved.

Much of what will be done by these professionals will be to rule out other problems. A pediatrician or a family doctor can help rule out possible diseases that can cause some of these same symptoms. He or she will also measure growth and development. If there is a disease or disorder related to hearing, you may be referred to an otolaryngologist--a physician who specializes in diseases and disorders of the head and neck.

To determine whether your child has a hearing function problem, an audiologic evaluation is necessary. An audiologist will give tests that can determine the softest sounds and words a person can hear and other tests to see how well people can recognize sounds in words and sentences. For example, for one task, the audiologist might have your child listen to different numbers or words in the right and the left ear at the same time. Another common audiologic task involves giving the child two sentences, one louder than the other, at the same time. The audiologist is trying to identify the processing problem.

A speech-language pathologist can find out how well a person understands and uses language. A mental health professional can give you information about cognitive and behavioral challenges that may contribute to problems in some cases, or he or she may have suggestions that will be helpful. Because the audiologist can help with the functional problems of hearing and processing, and the speech-language pathologist is focused on language, they may work as a team with your child. All of these professionals seek to provide the best outcome for each child.

What current research is being conducted?

In recent years, scientists have developed new ways to study the human brain through imaging. Imaging is a powerful tool that allows the monitoring of brain activity without any surgery. Imaging studies are already giving scientists new insights into auditory processing. Some of these studies are directed at understanding auditory processing disorders. One of the values of imaging is that it provides an objective, measurable view of a process. Many of the symptoms described as related to APD are described differently by different people.

Imaging will help identify the source of these symptoms. Other scientists are studying the central auditory nervous system. Cognitive neuroscientists are helping to describe how the processes that mediate sound recognition and comprehension work in both normal and disordered systems.

Research into the rehabilitation of child language disorders continues. It is important to know that much research is still needed to understand auditory processing problems, related disorders, and the best interventions for each child or adult. All the strategies undertaken will need to be suited to the needs of the individual child, and their effectiveness will need to be continuously evaluated. The standard for determining if a treatment is effective is that a patient can reasonably expect to benefit from it.
