From ICU wards to Dan Brown mysteries, unlocking the science behind terminal lucidity

Terminal lucidity, a rare phenomenon where patients regain clarity before death, is a documented medical reality. It occurs when patients with severe brain impairment due to strokes, tumours, or advanced dementia suddenly regain their memory and personality shortly before death. Recent neurological studies have shown a paradoxical spike in gamma wave activity in patients' final moments, suggesting that hypoxia may unlock dormant neural pathways, allowing memories and speech to return in a final, coherent burst.
