Neuropsychological evaluations were performed 3 weeks after the onset of stroke. His verbal repetition and writing to dictation were severely defective with phonemic substitutions. He was an alert patient but, he did not follow oral commands or respond to environmental sounds. Keywords: Auditory agnosia, Unilateral subcortical lesion This case suggested that the subcortical lesion involving unilateral acoustic radiation could cause generalized auditory agnosia. His auditory brainstem evoked potential and audiometry were intact. He could understand and read written words and phrases. He was not able to repeat or dictate but to perform fluent and comprehensible speech. We present a 73-year-old right-handed male with generalized auditory agnosia caused by a unilateral subcortical lesion. Subcortical lesions without cortical damage rarely causes auditory agnosia. Usually, either the bilateral or unilateral temporal lobe, especially the transverse gyral lesions, are responsible for auditory agnosia. ![]() Auditory agnosia is a deficit of auditory object processing defined as a disability to recognize spoken languages and/or nonverbal environmental sounds and music despite adequate hearing while spontaneous speech, reading and writing are preserved. The mechanisms and functional anatomy underlying the early stages of speech perception are still not well understood. ![]()
