Abstract
Here we report the case of an individual who developed proper- and common-name anomia with no category specificity, alexia with agraphia for kanji (Japanese morphograms), and mild verbal and semantic memory impairment after unilateral herpes simplex encephalitis. Although their common-name anomia, alexia with agraphia, and semantic memory impairment resolved within 2 years, this individual continued to experience proper-name anomia and verbal memory impairment. Encephalitic damage was limited to the left anterior temporal lobe (ATL), amygdala, hippocampus, and parahippocampal gyrus, sparing the mid-fusiform and posterior inferior temporal gyri. Although ATL lesions are not typically associated with semantic memory impairment, we suggest that damage to the left ATL can result in both proper- and common-name anomia, as was evident in the current case. In these cases, proper-name anomia may be more severe and persistent than common-name anomia, which may be mild and significantly improved within several years. In cases of semantic memory deficits, persistent common-name anomia, and severe alexia with agraphia, there is typically more extensive involvement of the temporal lobe than seen in the current case, including the mid-fusiform and posterior inferior temporal gyri.
期刊介绍:
Cognitive and Behavioral Neurology (CBN) is a forum for advances in the neurologic understanding and possible treatment of human disorders that affect thinking, learning, memory, communication, and behavior. As an incubator for innovations in these fields, CBN helps transform theory into practice. The journal serves clinical research, patient care, education, and professional advancement.
The journal welcomes contributions from neurology, cognitive neuroscience, neuropsychology, neuropsychiatry, and other relevant fields. The editors particularly encourage review articles (including reviews of clinical practice), experimental and observational case reports, instructional articles for interested students and professionals in other fields, and innovative articles that do not fit neatly into any category. Also welcome are therapeutic trials and other experimental and observational studies, brief reports, first-person accounts of neurologic experiences, position papers, hypotheses, opinion papers, commentaries, historical perspectives, and book reviews.
