Hyperacusis

Char, author at Chronically Hopeful, writes of sound sensitivity which she suffers daily but becomes worse during a flare.[1] Patients use ear protection
Whitney Dafoe is a very severely ill ME patient that must wear ear protection daily, even indoors

Hyperacusis is a debilitating hearing disorder where there is an increased sensitivity to certain frequencies and volume ranges of sound. Everyday sounds can be unbearable to the sufferer but will have no effect on others. Hyperacusis is often accompanied by Tinnitus.[citation needed] Hearing loss is a significant risk factor with both conditions.[citation needed]

Prevalence[edit | edit source]

Hyperacusis and Tinnitus have a prevalence of about 10–15%.[2]

Hyperacusis in ME/CFS[edit | edit source]

Symptom recognition[edit | edit source]

Hyperacusis is a symptom of ME recognized in the International Consensus Criteria's neurosensory symptoms, and counts towards the neurological symptoms required to diagnose ME or atypical ME (which is when symptoms are partially rather than fully met).[3]:7

Hypersensitivity to noise is mentioned as part of the "overload phenomenon" diagnostic symptom in the Canadian Consensus Criteria's Neurological/Cognitive Manifestations. The same section also refers to "sensory disturbances".[4]:11 It is can also be rated using the Symptom Severity and Severity Hierarchy Chart (Appendix 3), although sensitivity to light, noise, and odors is combined into as one item.[4]:102-103 Hyperacusis is recognized in the in the Visual and Auditory Disturbances part of the Signs and Symptoms list in Appendix 4.[4]:104

There is no reference to noise sensitivity in the more commonly used Fukuda criteria.
