Phonophobia and hyperacusis are two separate but closely related symptoms that are often mistakenly used in clinical practice as the same entity. Here we present a case report to highlight the distinguishing features of both and discuss the steps of management in these conditions. It is vital for the attending doctors to recognise hyperacusis and phonophobia as different entities to manage them...

Hyperacusis is described as abnormally sensitive hearing in which normally tolerable sounds are perceived as excessively loud (Stach, 1997). It is not associated with unusually low (good) thresholds for detecting sounds. In other words, the absolute threshold, as measured by the pure-tone audiogram, does not indicate hypersensitivity to very weak sounds. Rather, hyperacusis is manifested by ave...

This report is an attempt to bring to your attention some important information related to decreased sound tolerance and it is based on a short paper (Jastreboff, MM and Jastreboff PJ, Hyperacusis, Audiology Online, June 2001, http://www.audiologyonline.com). In particular, as we recently proposed a new term “misophonia” and we would like to provide some explanation and justification for it (Ja...

OBJECTIVE To determine whether phonophobia and dynamic mechanical (brush) allodynia are associated in episodic migraine (EM). METHODS Adult patients with EM were prospectively recruited. A structured questionnaire was used to obtain demographic and migraine related data. Phonophobia was tested quantitatively using a real time sound processor and psychoacoustic software. Sound stimuli were pur...

The present study aimed to describe the characteristics of auditory abnormalities present in cases of autism. One hundred and fifty six children with autism and 141 matched controls with language delay were investigated via direct observations combined with parent/caregiver reports. All of the autistic individuals demonstrated auditory abnormalities especially in the domain of hyposensitivity, ...

OBJECTIVE To evaluate the efficacy and tolerability of MAP0004 compared with placebo for a single migraine in adult migraineurs: The FREEDOM-301 Study. BACKGROUND Acute treatment of migraine remains a clinical challenge despite the availability of triptans and other agents. Injectable dihydroergotamine, although effective, is considered invasive and inconvenient, and intranasal dihydroergotam...
