title: Remote memory in a patient with circumscribed amnesia.
abstract: It has been suggested that extensive and severe remote memory loss is not a component of a circumscribed amnesic syndrome but may be attributable to problem solving and retrieval deficiencies associated with the frontal lobe damage which is present in some amnesic patients. In order to assess this notion, retrograde amnesia was studied in a patient, W.H., who had no apparent cortical damage revealed by radiological examination, and who evidenced no major cognitive deficiency other than amnesia. Regardless of whether remote memory was measured by recall or recognition procedures, patient W.H. exhibited impaired memory for information from the 1960s, 1970s, and 1980s, but was unimpaired in retrieving information from the 1940s and 1950s. These results demonstrate that retrograde amnesia can occur in patients who have a circumscribed memory deficit.
