Abstract

Profound loss of awareness for the past in amnesia has implications for our understanding of memory and belief systems, and how they may become disrupted in neurological conditions. We report the case of CW, a professional musician who became severely amnesic in 1985 following herpes simplex viral encephalitis (HSVE) at the age of 46 years. For many years CW stated several times a day that he had just woken up. He frequently wrote this in his diary too. When shown examples of his diary entries or videos of himself playing or conducting music, he recognised both his handwriting and himself on the video screen but stated vehemently that he “was not conscious then”. In a previous paper (Wilson, Baddeley, & Kapur 1995), it was suggested that this lack of awareness for the past was a delusion, defined as a strongly held belief in the face of contradictory evidence (rather than implying any kind of psychiatric disorder per se). As a contribution to the academic debate regarding theories of “self”, in the present paper we will review this explanation of CW's state as it had been in those early years, and we will also consider two other possibilities - namely, that CW had suffered from a loss of “autobiographical self” or “extended consciousness” (see Damasio, 2000, pp. 198-199), and that his verbal reports simply reflected a form of coping strategy to help him deal with the limited evidence he had available in “declarative” memory.
