Confabulation in aphasia.
We describe a brain-damaged patient who produced two distinctive forms of confabulation, typical and atypical (aphasic), both of which were associated with perseveration, poor self-monitoring, and denial of deficit. We propose that the typical confabulations are triggered by gaps in memory for the period surrounding the onset of his illness, while the aphasic (fantastic) confabulations are triggered by gaps in semantic representation. These observations suggest that confabulations may comprise a portion of the language deficit in patients with other varieties of fluent aphasia.
