Summary

The current conflicts in Afghanistan and Iraq have resulted in unprecedented rates of exposure to high-intensity blasts and resulting brain injury. This research team has established that recently blast-exposed Soldiers show differences from controls on tests of central auditory function. This project will 1) develop a more accurate estimate of the prevalence of central auditory dysfunction among Veterans exposed to blasts over the past ten years, 2) identify the functional outcomes associated with abnormal performance on tests of central processing, and 3) improve understanding of the ways in which blast-exposure resembles and differs from both the normal aging process and non-blast-related TBI in terms of performance on tests of central auditory processing.
