METHODS AND RESULTS In a patient with acute repetitive psychogenic amnesia, three different functional investigations (fMRI, electrica...
متن کاملSelf, memory, and imagining the future in a case of psychogenic amnesia.
We report a case of psychogenic amnesia and examine the relationships between autobiographical memory impairment, the self, and ability to imagine the future. Case study JH, a 60-year-old male, experienced a 6-year period of pervasive psychogenic amnesia covering all life events from childhood to the age of 53.
