Terminal Lucidity in People with Mental Illness and Other Mental Disability: An Overview and Implications for Possible Explanatory Models.

The literature concerned with experiences of the dying contains numerous accounts reporting the sudden return of mental clarity shortly before death. These experiences can be described as Terminal Lucidity (TL). The most peculiar cases concern patients suffering from mental disability including mental illness or dementia. Despite the potential relevance of TL for developing new forms of therapies and for elaborating an improved understanding of the nature of human consciousness, very little has been published on this subject. In this paper I present a historical overview and selected case reports of TL of mentally ill or otherwise disabled patients, mainly drawing on the literature available in English and in German. Possible explanatory models of TL and their implications are discussed. [ABSTRACT FROM AUTHOR]
