Auditory Processing Disorder (APD) or Central Auditory Processing Disorder (CAPD) is a hearing issue that affects around 5% of school-aged children. They may appear to have normal hearing, but get frustrated or act out in noisy environments or have trouble following verbal directions or conversations. It affects every part of their daily life, so it's important to find the causes and treat it as effectively as possible. | The National Association for Child Development (NACD)
