Summary
Functional hearing disorder (FHD) is a common cause of sudden hearing loss in children, affecting more girls than boys. Diagnosis involves audiological and neurological tests, with treatment focusing on cognitive-behavioral therapy.
Area of Science:
- Neurology
- Audiology
- Pediatrics
Background:
- Functional hearing disorder (FHD) is a type of Functional Neurological Disorder impacting hearing sensitivity.
- It is estimated to affect less than 2% of the general pediatric population, but up to 7% in children aged 6-17.
- FHD is considered a leading cause of sudden bilateral hearing loss in children, typically diagnosed around 11.3 years old and more prevalent in girls.
Purpose of the Study:
- To review the diagnosis of Functional Hearing Disorder.
- To discuss the treatment and management of Functional Hearing Disorder.
- To explore differential diagnoses and potential complications associated with Functional Hearing Disorder.
Main Methods:
- Diagnosis utilizes behavioral audiometry (pure-tone, speech) and physiological tests (imittance audiometry, otoacoustic emissions, auditory evoked potentials, functional neuroimaging).
- Review of existing literature on Functional Hearing Disorder diagnosis, treatment, and complications.
Main Results:
- Functional hearing disorder presents as a sudden, bilateral hearing loss across all frequencies, often linked to psychosocial conflict.
- Diagnostic criteria involve a discrepancy between subjective hearing loss and objective audiological findings.
- Treatment primarily involves cognitive-behavioral therapy, with psychiatric medications used as needed.
Conclusions:
- Functional hearing disorder is a distinct condition within Functional Neurological Disorders requiring specific diagnostic and therapeutic approaches.
- Early identification and intervention, particularly cognitive-behavioral therapy, are crucial for managing FHD in children.
- Further research into the underlying mechanisms and long-term outcomes of FHD is warranted.

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.

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....

01:15Auditory Pathway
5.9K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

01:13The Cochlea
46.2K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
