The characteristics of cognitive impairment in subjective chronic tinnitus

ConclusionsThis study reveals that tinnitus patients on the severe end of the spectrum may be at risk for serious cognitive deficits, which may not be a secondary response to disease manifestations but a primary feature of the underlying disease.

The mild tinnitus group and severe tinnitus group were assessed using the Cognitive Abilities Screening Instrument (CASI) and P300 event‐related potential. Severe tinnitus patients possess distinct cognitive deficits compared to mild tinnitus patients, a difference that could not be accounted for by differences in hearing loss. Our study reveals that tinnitus patients on the severe end of the spectrum may be at risk for serious cognitive deficits, which may not be a secondary response to disease manifestations but a primary feature of the underlying disease.
