The present review characterizes dual sensory impairment (DSI) as co-existing auditory and visual deficits in TBI that can be peripherally or centrally based. Current research investigating DSI in the military population, along with applicable research which focuses on unimodal deficits, is considered. Due to the heterogenous nature of TBI lesions, an important challenge that the clinician faces is ruling out the influence of multiple sensory deficits and/or the influence of cognitive processes on diagnosis and rehabilitation of the patient. Treatment options for DSI involve remediation of the sensory deficits via existing sensory aids or training exercises.
