ABSTRACT

Some patients, in the final stage of their life, suffer from mental state alterations that prevent them from adequately interacting with the environment. However, moments before their death (hours or days) they have a neurological improvement with no obvious explanation. In several hospitals in Mexico, this phenomenon is known among doctors as premortem well-being syndrome. Although there are no articles in scientific search engines in Spanish that refer to it as such, the phenomenon has been studied in world literature as terminal lucidity. This paper aims to define, comment on the reported cases and analyze the possible physiopathogenesis of this phenomenon.
