Confabulation
The production of false or invented memories without any intention to deceive. Unrelated to SDAM or aphantasia, but often confused with them.
Confabulation occurs in certain neurological conditions (Korsakoff’s syndrome, some frontal-lobe injuries) and is marked by confident recall of events that did not happen. It is not an imagery or autobiographical-memory deficit; it is an error in the monitoring of memory retrieval.
People with SDAM do not typically confabulate — they know what they do not remember. Confabulation is a different clinical picture entirely and warrants different assessment.
