Confabulation is a memory disturbance that is characterized by verbal statements and/or actions that inaccurately describe history, background, and present situations. Confabulation is considered “honest lying,” but is distinct from lying because there is typically no intent to deceive and the individual is unaware that their information is false. Although patients can present blatantly false information (“fantastic confabulation”), confabulatory information can also be coherent, internally consistent, and relatively normal. Individuals who confabulate are generally very confident about their recollections, despite evidence contradicting its truthfulness. The most known causes of confabulation are traumatic and acquired (e.g., aneurysm, edema) brain damage, and psychiatric or psychological disorders (e.g., schizophrenia, Alzheimer’s disease).
