“…It has been suggested that abnormalities in conscious recollection may reflect a breakdown in frontal strategic memory processes involved in both encoding and retrieval and executive functions linked to reality monitoring and decision making [13,14,16,19]. An impairment in strategic memory processes may result in a failure to bind together the separate aspects of an event into a distinctive whole.…”

“…For personal events, the patients exhibited a U-shaped curve, with the worst performance evident in the early adult period. More recently, Riutort et al [19] have investigated 24 patients with schizophrenia and 24 normal controls, also using the AMI. Autobiographical memory was impaired in the schizophrenic group, and this was most apparent after the onset of clinical symptoms.…”

Background: Recognition memory (RM) is impaired in patients with schizophrenia, as they rely largely on feelings of familiarity rather than conscious recollection. It has been suggested that this abnormality may reflect a breakdown in strategic memory processes involved in both encoding and retrieval. By studying 2 patients with false recognition (FR; patient C.T.) and delusional misidentification (DM; patient B.C.), and a group of psychotic control patients, we examined proposals that FR and DM exist on a continuum of increasingly severe impairment in strategic memory function. Methods: Executive function, autobiographical memory and verbal and facial RM were assessed using standard neuropsychological tests and the remember/know paradigm. Results: The psychotic control group displayed a significantly reduced reliance on remember judgements and compensatory elevation in know judgements on both RM tasks compared with the normal control group. Patient B.C. also followed this trend, but in a much more pronounced manner. In contrast, patient C.T. displayed a qualitatively different performance profile, which was marked by an increased dependence on remember responses. Conclusions: We have presented evidence which support proposals that a breakdown in strategic memory and executive dysfunction are more pronounced in DM than FR. However, the small sample size precludes any firm conclusions being drawn.

“…Psychiatric disorders: The case of schizophrenia Schizophrenia has been also associated with impaired AM [144][145][146] in the context of deficits in several cognitive operations (perception, memory) and emotional processing, caused very likely by a more general cognitionemotion disintegration [147] . FMRI examination of AM in schizophrenia revealed an abnormal pattern of activation and correlations with memory performance in the PFC and striatum, respectively [148] .…”

Episodic autobiographical memory (AM) allows one, through the recollection of sensory-perceptual details, thoughts and feelings, to become aware of an event as belonging to one's own past as well as being able to project into one's future. Because AM provides a sense of self-continuity, contributes to the integrity of the self, and helps predicting future experiences, any deficit of AM may have debilitating consequences for everyday life functioning. Understanding AM failure and the underlying neural mechanisms has the potential to shed light on brain reorganization mechanisms and engagement of compensatory processes. Functional magnetic resonance imaging (fMRI) provides the most promising imaging method to tackle these issues. We reviewed evidence from the few studies that used fMRI to investigate the functionality of the residual tissue, the neural reorganization and compensatory mechanisms in patients with neurological conditions due to impaired medial temporal lobe. Overall, these studies highlight the importance of the left hippocampus, which when atrophied and not functional leads to AM deficits but its residual functionality may support relatively normal AM recollection. When damaged hippocampal tissue is not functional, other brain regions (e.g. , the medial prefrontal cortex) may be involved to compensate impairment, but they appear generally ineffective to support detailed episodic recollection.© 2014 Baishideng Publishing Group Co., Limited.

These investigations are reviewed here. Overall, they highlight the importance of the left hippocampus, which when atrophied and not functional leads to deficits in AM but its residual functionality may support relatively normal AM recollection. When damaged hippocampal tissue is not functional, other brain regions (e.g. , the medial prefrontal cortex) may be involved to compensate impairment, but they appear generally ineffective to support detailed recollection.Denkova EJ, Manning L.
