Terminal Lucidity: A Review and Case Literature

Record summary

Terminal lucidity refers to reported episodes in which people with severe dementia or neurological impairment display unexpected clarity shortly before death. Michael Nahm and other authors collected historical and modern cases, presenting them as a challenge to straightforward brain-based assumptions about cognition. The reports are valuable for comparison with hospice testimony and altered-state claims, but documentation is often retrospective, clinically incomplete and vulnerable to definitional drift. Conventional explanations include fluctuating cognition, observer interpretation and unrecognized residual capacity.
