Non-Organic Hearing Loss

Summary about Disease


Non-Organic Hearing Loss (NOHL), also known as functional hearing loss, pseudohypacusis, or exaggerated hearing loss, is a condition where a person presents with hearing loss that is inconsistent with objective audiological testing results. In simpler terms, individuals with NOHL either consciously or unconsciously exaggerate or feign hearing loss. It's important to distinguish NOHL from genuine organic hearing loss caused by physical damage to the ear or auditory system.

Symptoms


Inconsistent responses during hearing tests.

Exaggerated reactions to sounds.

Difficulty understanding speech that is inconsistent with the reported hearing loss.

Better speech discrimination scores than expected based on audiogram.

Complaints of hearing difficulties that don't match their ability to function in daily life.

Possible inconsistencies in communication skills (e.g., responding appropriately to quiet speech sometimes but not others).

Causes


The causes of NOHL can vary and may include:

Psychological factors: Stress, anxiety, depression, or conversion disorder.

Financial gain: Seeking disability benefits or compensation.

Attention-seeking: To gain attention or sympathy.

Avoiding responsibilities: As an excuse to avoid unwanted tasks or situations.

Underlying medical conditions: Rare occasions where a physical ailment manifests as auditory symptoms.

Medicine Used


There is no specific medication for NOHL. Treatment focuses on addressing the underlying cause, which may involve:

Psychological therapy: Cognitive-behavioral therapy (CBT), counseling, or other forms of therapy to address emotional or psychological issues.

Addressing secondary gain: Helping the individual understand and resolve the underlying reasons for the behavior, such as financial concerns or relationship issues.

Is Communicable


No, non-organic hearing loss is not a communicable disease. It is not caused by an infectious agent and cannot be transmitted from one person to another.

Precautions


There are no specific precautions to prevent NOHL. However, addressing underlying psychological issues and ensuring fair and transparent processes for disability claims can help reduce the incidence.

How long does an outbreak last?


NOHL is not an outbreak-related condition. The duration of the presented symptoms can vary significantly depending on the underlying cause and the individual's response to treatment. It may resolve quickly with counseling, or persist longer if the underlying issues are more complex.

How is it diagnosed?


NOHL is diagnosed through a combination of audiological tests and clinical observations. Key diagnostic indicators include:

Inconsistencies in audiometry: Varying responses between tests.

Stenger Test: This test is used for unilateral cases to determine if a person is feigning deafness in one ear.

Acoustic Reflex Thresholds: Discrepancies in reflex thresholds can be indicative of NOHL.

Observation of behavior: Noting inconsistencies in the patient's responses and communication abilities.

Speech Recognition Scores: An individual demonstrating far better speech recognition scores than what would be expected given their stated hearing loss thresholds would suggest potential NOHL.

Otoacoustic Emissions (OAEs): Presence of OAEs indicates normal cochlear function, which may contradict claimed hearing loss.

Auditory Brainstem Response (ABR): Can objectively assess hearing thresholds, bypassing patient's conscious responses.

Timeline of Symptoms


The onset of symptoms can be sudden or gradual. There is no specific "timeline" as it depends on the trigger and the individual's psychological state. The duration of the symptoms also varies greatly, ranging from short-term episodes to chronic presentation.

Important Considerations


It is crucial to approach individuals suspected of NOHL with sensitivity and understanding.

It's important to rule out genuine organic hearing loss first.

Accusations of feigning hearing loss should be avoided until a thorough evaluation has been conducted.

Collaboration between audiologists, psychologists, and other healthcare professionals is essential for accurate diagnosis and effective management.

Addressing the underlying cause is critical for successful treatment.
