Confabulation

Here is the Wiki Definition. In psychology, confabulation (verb: confabulate) is a memory disturbance, defined as the production of fabricated, distorted or misinterpreted memories about oneself or the world, without the conscious intention to deceive.[1] Confabulation is distinguished from lying as there is no intent to deceive and the person is unaware the information is false.[2] Although individuals can present blatantly false information, confabulation can also seem to be coherent, internally consistent, and relatively normal.[2] Individuals who confabulate present incorrect memories ranging from "subtle alterations to bizarre fabrications",[3] and are generally very confident about their recollections, despite contradictory evidence.[4] Most known cases of confabulation are symptomatic of brain damage or dementias, such as aneurysm, Alzheimer's disease, or Wernicke–Korsakoff syndrome (a common manifestation of thiamine deficiency caused by alcoholism).[5]
