CAPD and ADHD
CAPD and ADHD have been linked for decades, and many individuals live with both conditions simultaneously. Though they share overlapping traits — difficulty focusing, trouble following instructions, and struggles in noisy environments — they are distinct conditions that require separate evaluations and different approaches to support.
Why They Are Easily Confused
Because CAPD and ADHD present so similarly, misdiagnosis is common. A child who has difficulty paying attention in school may be identified as having ADHD when CAPD is actually present — or both conditions may exist at the same time. This diagnostic gap has been well documented in the literature. As early as 1992, Dr. William Keller cautioned that a diagnosis of ADHD should not be made without first ruling out the possibility that CAPD might be mimicking it. More recent research has helped clarify the distinction: individuals with CAPD often show signs of inattention and distractibility specifically when background noise is present, but not in quiet environments (Chermak & Bellis, 2014). This is an important clinical marker that points to the auditory system, rather than attention itself, as the underlying factor.
They Require Different Specialists
ADHD is typically diagnosed by a pediatrician, psychologist, or psychiatrist. CAPD requires a separate evaluation by an audiologist with specialized training in central auditory processing. An ADHD evaluation cannot diagnose CAPD, and vice versa — both evaluations may be necessary to get a complete picture.
Signs a CAPD Evaluation May Be Warranted
Consider pursuing a CAPD evaluation if any of the following apply:
- ADHD intervention is not fully effective. If an individual continues to struggle with listening, focus, or following verbal instructions despite treatment, CAPD may also be a contributing factor.
- Classroom difficulties persist. Trouble tracking instructions or maintaining attention in group settings can indicate auditory processing difficulty.
- Sounds feel overwhelming. CAPD makes it difficult to filter competing background noise. This is a neurological challenge, not a behavioral choice.
- Social or emotional frustration is present. The sustained effort required to process sound can lead to exhaustion, withdrawal, or being perceived as disengaged.
- Reading and spelling challenges continue. When CAPD and ADHD co-exist, language-based learning difficulties often intensify.
A Note for Families
You know yourself and your child better than anyone. If you feel something is being overlooked, advocating for a thorough evaluation is always appropriate. With accurate diagnosis and the right support, individuals with CAPD and ADHD can thrive.

"Our children can be our greatest teachers if we are humble enough to receive their lessons." - Bryan McGill
If we listen to and observe our children, they will tell us everything we need to know about how they are impacted by their auditory environment. The classic behaviors associated with CAPD are easy to identify, if one understands what to look for. CAPD should be considered and investigated when there are concerns and indicators to do so.
