Prosopamnesia and Visuolimbic Disconnection Syndrome: A Case Study
نویسندگان
چکیده
After a head injury, a 58-year-old patient presented a severe deficit in face recognition. Bilateral temporo-occipital hematomas were drained. Associated with this deficit in face recognition, the patient presented visual hypoemotionality (hyporeactivity to visual stimuli) and transient gustatory amnesia. Some topographic amnesia and mild anomia were also present. Five years later, difficulties in face recognition and visual hypoemotionality remained unchanged. It was observed that the major impairment was related to a lack of memory for faces. Defects in visual imagery were also present. Some distinctions between agnosia for faces (prosopagnosia) and amnesia for faces (prosopamnesia) are introduced. The brain mechanisms of prosopagnosia,prosopamnesia, and visual hypoemotionality are considered.
