Auditory processing disorder (APD) is a hearing problem that affects about 5% of school-aged children. Kids with this condition, also known as central auditory processing disorder (CAPD), can't process what they hear in the same way other kids do. This is because their ears and brain don't fully coordinate.It's important to note that APD is a hearing disorder. It isn't the result of other conditions that may affect understanding or attention, such as autism spectrum disorder (ASD) or attention deficit hyperactivity disorder (ADHD). However, in some cases, APD can occur along with these conditions.Processing disorders, like Auditory Processing Disorder (APD), Visual Processing Disorder, and Sensory Processing Disorder (SPD) are caused by a deficiency in a person's ability to effectively use the information gathered by the senses
