Patient‐reported auditory handicap measures following mild traumatic brain injury

Abstract: Objectives/Hypothesis Few studies have specifically addressed auditory complaints in patients with nonblast mild traumatic brain injury (mTBI). Herein, we aimed to investigate auditory symptoms in patients following mTBI using patient‐reported outcome measures. Study Design Retrospective analysis of prospectively collected data in a tertiary‐care hospital. Methods The patients included those with mTBI (cases) and those without mTBI (controls). Individuals (≥18 years old) with and without mTBI were screened. Ex… Show more

“…Hyperacusis is the condition of reduced tolerance or increased sensitivity to sound, and is characterized by excessive loudness, troublesomeness, anxiety, and pain when the person is exposed to sound (58,59). Auditory symptoms including subjective hearing loss, tinnitus, and hyperacusis are common in those with mTBI, and 67.3% of non-blast mTBI patients reported hyperacusis according to a recent patientreported outcome measures study (60). Mechanisms underlying hyperacusis following mTBI are unknown, although proposed theories suggest a tonotopic reorganization and hyperexcitability of the auditory cortex involving a malfunction of 5-HT (61), a release of endogenous opioid peptides (62), and a decreased GABA A -mediated inhibition in the inferior colliculus (63).…”
