Disorders associated with confabulation

Most clinicians would agree that confabulation is always accompanied by amnesia and lack of insight. But is this true? Do confabulating patients really need to have a gap in memory? This chapter explores the complex relation between confabulation and amnesia, disorientation, and false recognition and compares it with disorders provoking false statements about the current situation, the place, people, or one’s own health status, as it happens in disorders such as déjà vu, reduplicative paramnesia, Capgras and Fregoli syndromes, intermetamorphosis, and anosognosia. Elegant recent experiments have revealed a new mechanism of anosognosia for hemiplegia, but its status among confabulations remains disputable.
