APD stands for Auditory Processing Disorder, a condition that affects the brain's ability to process and interpret sounds. It is not a hearing loss, but rather a problem with how the brain understands and uses auditory information. APD can affect individuals of all ages, but it is commonly diagnosed in children. An audiologist or a speech-language pathologist with expertise in APD can diagnose the condition through a series of comprehensive assessments that evaluate various auditory processing skills. It is important to consult with a qualified professional for an accurate diagnosis and appropriate management strategies.
