چکیده انگلیسی
Disorientation is frequent after brain damage. It is a constituent component of post-traumatic amnesia and was part of the original definition of the Korsakoff syndrome, together with amnesia and confabulations. Orbitofrontal reality filtering is a pre-conscious memory control process that has been held accountable for disorientation and a specific type of confabulations that patients act upon. A recent study questioned the specificity of this process and suggested that confabulating patients who failed in orbitofrontal reality filtering similarly failed to monitor the precise content of memories, a critical step within the strategic retrieval account, which describes a series of processes leading up to the recollection of memories. In the present study we combined the proposed experimental requirements of both processes in a single continuous recognition task and tested a group of 21 patients with a matched deficit of delayed free recall. We found that only deficient reality filtering, but not content monitoring, significantly correlated with disorientation and distinguished between confabulators and non-confabulators. Thus, reality confusion, as evident in disorientation and behaviourally spontaneous confabulation, primarily reflects an inability to monitor memories' relation with ongoing reality rather than to monitor their precise content.
