Confabulation
From Wikipedia, the free encyclopedia
Wiktionary, the free dictionary.
Confabulation is the confusion of imagination with memory, and/or the confusion of true memories with false memories.
Patients with Korsakoff's syndrome characteristically confabulate by guessing an answer or imagining an event and then mistaking their guess or imagination for an actual memory. A fictional example of this appeared in the Fox Network series House M.D. where a young woman in the emergency room was giving interns different stories as to what happened to her, so naturally the interns thought she was lying. However, Dr. House discovered this was due to the effects of Korsakoff's syndrome when she fabricated a final story involving images on his pen and clipboard. The (fictional) patient wasn't lying, but because of her lack of memory (as said above), she mistook her guesses for reality.
Confabulation can also occur as a result of damage to the Anterior communicating artery (ACoA), in the Circle of Willis.
Confabulation also appears to be a common occurrence in normal individuals under experimental circumstances, as shown by research on choice blindness. [1]
Some military agents, such as BZ, and deliriant drugs such as those found in datura, noticeably scopolamine and atropine, may also cause confabulation.
