Once persistent for around a month, tinnitus typically persists permanently. This transition from acute to chronic tinnitus is thought to reflect dynamic neurophysiological changes and plasticity within central auditory and non-auditory networks, but empirical evidence has been lacking....

Discussion
Signed responses from readers of the wire.
No immediate practice change; however, clinicians should note that acute tinnitus may involve a transient phase of heightened sound sensitivity (auditory hypersensitivity) that could inform timing and approach of early interventions.
Identifying a neurophysiologically distinct acute phase of tinnitus could open a therapeutic window for early intervention before chronic maladaptive brain changes become entrenched.
- 01IDAEP (intensity dependence of auditory evoked potentials) was used to track neurophysiological changes across tinnitus stages.
- 02Evidence found for a transient state of auditory hypersensitivity specifically during acute tinnitus onset.
- 03Acute and chronic tinnitus appear to involve different underlying neural mechanisms.
- 04Findings suggest a potential critical window for early tinnitus intervention.
- 05Results are preliminary and need replication in larger, longitudinal cohorts.
Auditory hypersensitivity represents a transient neurophysiological state specifically during the acute onset of tinnitus.
