“…More consistent findings have been reported: (1) on the disorganizing effect of (especially negative) affect-laden topics on speech production [20] and (2) on the disturbance of autobiographical [21] and emotional [22] memory in SSD. When conversing on or recalling topics that elicit EmEx, the specificity and coherence of the narrative produced in SSD is markedly impaired.…”

Background: Although it has been suggested that disturbances in emotion experience and regulation play a central role in the aetiology and psychopathology of schizophrenia spectrum disorders, the phenomenology of emotion experience in schizophrenia remains under-researched. Sampling and Methods: In-depth interviews were conducted twice with each of the 20 participants (firstly at admission and secondly 6 months later). Data collection and analysis were guided by the principles of phenomenological study of lived experience. Results: The emotion experiences described by our participants vary greatly in both quality and intensity, but appear to have a common phenomenology. Anxiety is reported as the basic emotion which buffers, transforms and sometimes supplants all others. Emotions in general are experienced as foreign, unstable and perturbing, thereby contributing greatly to feelings of ambivalence, perplexity and an unstable sense of self in general. Conclusions: The findings of this study have important therapeutic and theoretical implications because they suggest that emotion experiences in schizophrenia spectrum disorders may underlie a wide range of psychopathological phenomena in both the cognitive and social functioning domains. Due to the relatively small sample size and its selection from psychotherapeutic units, the results may not be generalizable to all schizophrenia patients.

“…All our inferences about the nature of EmEx - especially those pertaining to EmEx long past, i.e. from the pre-psychotic phase - must therefore be qualified to a certain extent, as we cannot be sure to what degree they reflect disturbances of (autobiographic) memory [21,22]. …”

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.

“…Marková [15] a récemment proposé conceptuelle, c'est-à-dire un syndrome dysexécutif sous-jacent [1,23]. Enfin, certains auteurs proposent un lien entre le déficit d'insight des patients schizophrènes et un trouble spécifique de l'identité narrative, de la conscience qu'a le sujet de sa propre identité dans un temps subjectif, c'est-à-dire une altération de sa conscience autonoétique [9,23,28].…”

“…Nos résultats préliminaires suggèrent que l'altération de la conscience autonoétique mise en A c c e p t e d M a n u s c r i p t 7 évidence chez les sujets schizophrènes [9] soit à l'origine de l'altération de l'insight, ce qui a déjà été avancé par d'autres auteurs [23,28]. Nous nous proposons de poursuivre les inclusions, les évaluations de l'insight, et enfin d'étudier les interactions existantes entre les différents sous-ensembles du RMD afin de préciser le mécanisme principal de l'altération de l'insight : perturbation de la représentation du Soi, altération de la conscience autonoétique, ou trouble du jugement à proprement parler.…”
