Hyperthymesia (HSAM) - Wikipedia

Hyperthymesia



Hyperthymesia is the condition of possessing an extremely detailed autobiographical memory. People with hyperthymesia remember an abnormally vast number of their life experiences.
American neurobiologists Elizabeth Parker, Larry Cahill, and James McGaugh (2006) identified two defining characteristics of hyperthymesia: spending an excessive amount of time thinking about one's past, and displaying an extraordinary ability to recall specific events from one's past.[1] The word "hyperthymesia" derives from Ancient Greek: hyper- ("excessive") and thymesis ("remembering").


Signs and symptoms

Individuals with hyperthymesia can recall almost every day of their lives in near perfect detail, as well as public events that hold some personal significance to them. Those affected describe their memories as uncontrollable associations; when they encounter a date, they "see" a vivid depiction of that day in their heads.[3] Recollection occurs without hesitation or conscious effort
