Impairments in dichotic listening in patients presenting anterior communicating artery aneurysm

Applied Neuropsychology

Abstract

Impaired dichotic listening has been documented in numerous etiologies, but there is limited information on patients who present with anterior communicating artery (ACoA) aneurysm. The sequelae following ACoA aneurysm is frequently associated with neurobehavioral impairments, such as confabulation, memory, and behavior, as a result of the areas of innervation (DeLuca, 1992; DeLuca & Diamond, 1995). Clinical experience, however, shows ACoA aneurysm to also be associated with impairments in dichotic listening. Participants in this study were divided into 2 groups: patients who presented with ACoA aneurysm with age-matched controls, and patients who presented moderate to severe traumatic brain injury (TBI) with age-matched controls. TBI patients were included for test-validity purposes and to allow a comparison between diffuse and focal cerebral damage. Dichotic listening results revealed a similar pattern for patients with ACoA aneurysm and those with brain injury. The findings suggest that central auditory pathways are susceptible to damage following ACoA aneurysm.
