Other healthcare providers may also help assess your child. This is often the earliest age that an audiologist will diagnose CAPD. These kinds of tests are often not reliable in children under 7 years of age. It can assess the nerve pathways and help locate the problem. This test is also known as the brainstem auditory evoked response (BAER). They are connected to a computer, which records brain activity in response to sound. This uses electrodes placed on your child’s head. An example is the auditory brainstem response (ABR) test. In some cases, an audiologist may give tests to measure the brain’s response to sound. The tests might assess your child’s:Ībility to tell where a sound comes from (localize a sound)Ībility to tell the difference between sounds (sound discrimination) Your child will be asked to listen to a variety of sounds and then respond to them in some way. The audiologist may give a series of tests in a soundproof room. The provider uses signs, testing, and other information to figure out a child’s hearing problem. A healthcare provider trained in hearing problems (audiologist) can diagnose CAPD. Many of these signs are similar to those of other disorders. Diagnosing CAPDĮven if your child has signs of CAPD, he or she might not have CAPD. Your child may not have all of these signs. Tell where a sound comes from (localize a sound) Telling the difference between similar speech sounds Understanding speech in a noisy environment Children with CAPD may have problems with: Or he or she may ask you to repeat what you’ve said. For example, you may notice that your child often asks what you mean. Signs of CAPDĪ child with CAPD may show a variety of problems with listening. This may be because a problem with the central auditory system can’t be detected. In most cases the cause of CAPD is not known. This problem may be:Įxposure to a toxic substance, such as leadĪutoimmune diseases, such as multiple sclerosis In some cases a specific problem may cause it. Having certain genes may increase your child’s risk for CAPD. Researchers are still trying to understand what causes CAPD. This can cause your child to have trouble interpreting certain kinds of sounds. Researchers think the problem happens between the sensory systems in the ear and the central auditory system in the brain. In some cases part of this process goes wrong. The process needs several parts of the brain to work together, so that you can pay attention to and understand the sound. At the same time, the brain highlights important sounds, such as the speech in a conversation. The brain must ignore certain background sounds. Then the brain mixes this information with signals from other parts of the brain. The part of the brain that controls hearing is called the central auditory system. The sound causes signals to pass along nerves to the brain. It causes a child to have trouble hearing and understanding speech and sounds. It may be from a problem with the way the brain processes sound (auditory) information. Understanding Central Auditory Processing Disorder (Child)Ĭentral auditory processing disorder (CAPD) is a problem with listening.
