The purpose of this paper is to provide an overview of the behavioral and neuroscience research on confabulation. While most forms of organically induced confabulatory syndromes are reviewed, special emphasis on confabulation following anterior communicating artery (ACoA) aneurysm is provided. “Psychiatric” forms of confabulation will not be discussed at length in this paper. For instance, while confabulation has been observed in patients with schizophrenia, such a presentation appears to be related to a thought disorder (Nathaniel-James and Frith, 1996). This paper will focus on confabulation following acquired brain damage.
