![]() ![]() ![]() The effect of APD can be worsened by the presence of other conditions, such as dyslexia, language processing difficulties, poor attention and poor short-term memory. Some children have a greater range of difficulties than others. Once the sound has arrived in the brain, there are problems with interpreting it, for instance, recognising the sound or understanding speech.Įach person is affected in a different way and to a different degree, so APD may be called a ‘spectrum disorder’. It then travels to the brain through the auditory nerve. When someone has APD, sound enters the ear canal and passes through the middle and inner ear as usual. The brain then interprets these nerve impulses as sound. The movement of the fluid in the cochlea stimulates the hair cells inside it to trigger a nerve impulse, which is carried to the brain by the auditory nerve. The sound then passes through the middle ear via the three small bones of hearing (ossicles) on to the inner ear, which is filled with fluid. ![]() Sound waves enter the ear canal and cause the eardrum to vibrate. Tests for ADHD include gathering first-hand information about the child’s behaviors from parents, teachers and school records and having a psychologist interview and observe the child.The ear consists of three parts, the outer ear, the middle ear and the inner ear. Testing for APD includes hearing, language and speech assessments and cognitive testing which can show how well the child’s brain is processing information. ADHD is impairment of the brain’s “executive functioning” area found in the prefrontal lobe of the brain.Ī child suspected of having APD or ADHD should be given the appropriate tests necessary to determine if they have one disorder or both disorders. Auditory processing disorder (APD) is a condition in which the brain has difficulty processing and interpreting sounds, including speech. Instead, children with ADHD are hyperactive, have poor impulse control and procrastinate when given a task to complete. However, ADHD is not a central nervous system disorder but a neurodevelopmental and behavioral disorder that does not involve problems with the way the brain processes auditory information. Signs of auditory process disorder are often misdiagnosed as signs of ADHD because many symptoms of both conditions overlap. Academic difficulties particularly involving subjects that require the child to hear and interpret a teacher’s instructions.Acting upset or unsettled in noisy places.Problems following directions in school and at home.Being easily distracted, forgetful and disorganized.For example, a child with APD may confuse the meaning of the words “ball” with “wall” or “bat” with “cat”, especially when they are in environments with background noises, such as playgrounds, cafeterias and classrooms. Children with APD primarily experience difficulty interpreting speech because they are unable to recognize important differences between word sounds. The words seventy and seventeen may sound the same. For example, they may not recognize the difference between cat, that, and bat. ![]() But people with APD don’t pick up on the subtle differences between them. Auditory processing disorder (APD) is thought to be a central nervous system dysfunction involving the way the brain processes auditory input. Auditory processing disorder (APD) is a term that refers to problems in how the brain understands speech. ![]()
