Abstract:
Bilateral lesions damaging the primary auditory cortex or the auditory radiation may cause auditory agnosia. We describe a 67-year-old woman with auditory agnosia after bilateral thalamic hemorrhage. Initially, she showed subcortical deafness for words and environmental sounds. Pure tone audiometry showed a moderate-to-severe hearing loss (mean hearing level, right 56 dB ; left 57 dB), while the recording of auditory brainstem response was normal. Brain CT demonstrated a hematoma in the left thalamus and a narrow low density area suggesting a sequel of the right thalamic hemorrhage. Hearing training was begun using sound sources that were easily recognizable for the patient. Her recognition was better for words than for individual Japanese vowel or consonant-vowel sounds, and the use of lip reading contributed to her better recognition of words. After 2 months, she was able to communicate with medical staff and family members in daily conversation.
