Study Summary
Tinnitus, commonly referred to as "ringing in the ears", affects 50 million people in the United States and is recognized as a major public health concern. Tinnitus is the most frequent cause of service-connected disability claims among war veterans. Tinnitus remains a subjectively diagnosed entity. There is no standardized objective method of diagnosing tinnitus or describing the functional impact of the condition. Currently, physicians have to rely on patient-based self reports. Without an objective method of diagnosing tinnitus and describing the functional implications, adequate treatment delivery is also hampered since there is no way to objectively stratify patients into severity groups and assess response to treatment. Because tinnitus is known to negatively affect cognition through the ventral attention networks and the prefrontal cortex, measuring cognitive processing speed is a possible way to objectively measure tinnitus. This study builds on previous work the investigators have done that utilized a quick, easily accessible measure of auditory processing speed. That earlier study showed a correlation between that measure and self reported measures of tinnitus severity, and this study attempts determine a more precise estimate of that correlation. It also better validates those results by including a traditional neurocognitive measuring cognitive speed and by controlling for the presence of depression and somatoform disorders.
Primary Outcome
Standardized Z-scores of the Brain Speed Test (BST-Z scores) calculated based on age group-matched normal population data were used for analysis in order to control for the impact of age on test scores. Age-standardized Z-scores, which reflect the distance from the mean in standard deviation values, allow for the comparison of scores across age groups. A z-score of 0 indicates a value of the average, while absolute z-score values above 2 indicate observations significantly different from normal
