Summary
The prevalence of Central Auditory Processing Disorder (CAPD) in children aged 6-18 was 0.7%, with higher rates observed in males and lower socioeconomic groups. Key symptoms included academic difficulties and challenges with auditory processing, particularly speech perception in noise.
Area of Science:
- Audiology
- Pediatric audiology
- Neuroscience
Background:
- Central Auditory Processing Disorder (CAPD) involves difficulties processing auditory signals, distinct from hearing or cognitive impairments.
- Prevalence and demographic data for pediatric CAPD remain debated due to varying diagnostic criteria.
- Previous estimates of CAPD prevalence range widely from 0.5% to 7%.
Purpose of the Study:
- To determine the prevalence of CAPD in children aged 6-18 years.
- To identify demographic characteristics associated with CAPD in pediatric populations.
- To understand the common symptoms and affected auditory processes in children diagnosed with CAPD.
Main Methods:
- A retrospective study was conducted using data from 3537 ear-related cases reported between June 2017 and July 2019.
- Audiology Outpatient Department (OPD) records from the All India Institute of Speech and Hearing were reviewed.
- Thirty-two cases diagnosed with CAPD within the specified age range were analyzed.
Main Results:
- The prevalence of CAPD among the studied pediatric population was 0.7%.
- CAPD was found to be more prevalent in males and individuals from lower socioeconomic backgrounds.
- Commonly reported symptoms included poor academic performance and difficulty following instructions, with speech perception in noise being the most affected auditory process.
Conclusions:
- The study highlights a 0.7% prevalence of CAPD in children aged 6-18.
- Males and children from lower socioeconomic backgrounds represent vulnerable populations for CAPD.
- Auditory processing deficits, especially in noisy environments, significantly impact academic performance and daily functioning.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
