Abstract
Autobiographical-episodic memory is considered to be the most complex of the five long-term memory systems. It is autonoetic, which means, self-reflective, relies on emotional colorization, and needs the features of place and time; it allows mental time traveling. Compared to the other four long-term memory systems-procedural memory, priming, perceptual, and semantic memory-it develops the latest in phylogeny and ontogeny, and is the most vulnerable of the five systems, being easily impaired by brain damage and psychiatric disorders. Furthermore, it is characterized by its fragility and proneness to distortion due to environmental influences and subsequent information. On the brain level, a distinction has to be made between memory encoding and consolidating, memory storage, and memory retrieval. For encoding, structures of the limbic system, with the hippocampus in its center, are crucial, for storage of widespread cortical networks, and for retrieval again a distributed recollection network, in which the prefrontal cortex plays a crucial role, is engaged. Brain damage and psychiatric diseases can lead to what is called "focal retrograde amnesia." In this context, the clinical picture of dissociative or functional or psychogenic amnesia is central, as it may result in autobiographical-emotional amnesia of the total past with the consequence of an impairment of the self as well. The social environment therefore can have a major impact on the brain and on autobiographical-episodic memory processing. This article is categorized under: Psychology > Memory.

Sheikh MA. Confounding, Mediation, or Independent Effect? Childhood Psychological Abuse, Mental Health, Mood/Psychological State, COPD, and Migraine.

Abstract
In some settings, it may be difficult to differentiate between a confounder and a mediator. For instance, the observed association of self-reported childhood psychological abuse (CPA) with onset of chronic obstructive pulmonary disease (COPD) and migraine may be confounded by current mood/psychological state (e.g., the subjective evaluation of one's own affective state), as well as mediated by an individual's psychopathological symptoms. In this study, we propose the "independence hypothesis," which could prove meaningful to explore in data that lack prospective or objective indices of CPA. We used cross-sectional data from wave VI (2007-2008) of the Tromsø Study, Norway (N = 12,981). The associations between CPA and COPD and migraine were assessed with Poisson regression models. CPA was associated with a 46% increased risk of COPD (relative risk [RR] = 1.46, 95% confidence interval [CI]: [1.02, 1.90]) and a 28% increased risk of migraine in adulthood (RR = 1.28, 95% CI: [1.04, 1.53]), independent of age, sex, parental history of psychiatric problems/asthma/dementia, smoking, respondent's mood/psychological state, and mental health. These findings suggest that the association between retrospectively reported CPA and COPD and migraine is not driven entirely by respondent's mood/psychological state and mental health. Assessing the independent effect of self-reported CPA on COPD and migraine in retrospective studies may prove more meaningful than exploring the mediating role of mental health. Here, we provide the analytical rationale for assessing the independent effect in settings where it is difficult to differentiate between a confounder and a mediator. Moreover, we provide a theoretical rationale for assessing the independent effect of retrospectively reported childhood adversity on health and well-being.

Abstract
The experience of early life stress (ELS) is a risk factor for memory dysfunction, but the impact at the neural level is less clear. The aim of this study is to investigate whether healthy people with a higher ELS display more structural and functional changes of hippocampus than people with a lower ELS, and to investigate whether hippocampus changes in turn affects memory. The Childhood Trauma Questionnaire (CTQ) was used to assess ELS in 100 young health participants. They were divided into two groups: "low" CTQ group (limitation of none/minimal ELS) and "high" CTQ group (low to moderate ELS). Verbal memory was assessed by California Verbal Learning Test II and visual memory by Rey-Osterrieth Complex Figure. Resting state fMRI data were acquired and voxel-wise correlation analysis was performed to functionally divide the hippocampus. Gray matter volumes and memory circuits of the anterior and posterior hippocampus were analyzed. We also tested whether changes in hippocampus mediated the relationship between ELS and memory. Compared with participants with a lower ELS, healthy participants with a relatively higher ELS had reduced anterior hippocampal functional connectivity, which positively correlated with visual memory. Among all participants, anterior hippocampal functional connectivity mediated the relationship of ELS on visual memory. These findings suggest that ELS decreased anterior hippocampal-cortical functional connectivity, which, in turn, drives memory decline and highlight a potential pathway in which ELS affects memory by degrading anterior hippocampal functional connectivity changes directly.

Abstract
Several researchers have raised the concern that the cross-sectional association of retrospectively reported childhood adversity with self-reported onset of asthma and chronic bronchitis in adulthood may be confounded, as well as mediated by an individual's mental health. The aim of this study was to assess the effect of retrospectively reported childhood adversity on self-reported onset of asthma and chronic bronchitis in adulthood, independent of potential confounding and mediating variables (including respondent's mental health). We used data collected in 2007-2008 within the framework of the Tromsø Study (N = 12,981), a representative study of adult men and women in Norway. The associations of childhood adversity with asthma and chronic bronchitis were assessed with Poisson regression models. Relative risks (RR) and 95% confidence intervals (CI) were estimated with bias-corrected bootstrapping. Childhood adversity was associated with a 9% increased risk of asthma (RR = 1.09, 95% CI: 1.02, 1.16) and a 14% increased risk chronic bronchitis (RR = 1.14, 95% CI: 1.03, 1.26) in adulthood, independent of age, sex, parental history of psychiatric problems/asthma/dementia, education, smoking, social support, and respondent's mental health. Controlling for indicators of respondent's mental health reduced the strength of associations of childhood adversity with asthma and chronic bronchitis; however, the associations were still present in the same direction (p < .05). These findings suggest that the association of retrospectively reported childhood adversity with asthma and chronic bronchitis is independent of respondent's mental health. We recommend controlling for indicators of the respondent's mental health to assess an unbiased association of retrospectively measured childhood adversity with self-reported asthma and chronic bronchitis.

Abstract
OBJECTIVE Many researchers view retrospective reports with skepticism. Indeed, the observed association between retrospectively-reported childhood disadvantage (CD) and morbidity in adulthood has been criticized as an artefactual correlation driven by the psychological state of the respondent at the time of reporting (current psychological state). The aim of this study was to assess the role of current psychological state in the association between childhood disadvantage and morbidity in adulthood. METHODS The present analysis used cross-sectional data collected in 2007-2008 within the framework of the Tromsø Study (N = 10,765), a representative study of adult men and women in Norway. The association between CD and the physical health outcomes heart attack, angina pectoris, chronic bronchitis/emphysema/COPD, diabetes mellitus, hypothyroid/low metabolism, migraine, hypertension, and comorbidity (i.e., the sum of these physical health outcomes) was assessed with Poisson regression models. Relative risks (RR) and 95% confidence intervals (CI) were estimated. A wide range of indicators of respondents' current psychological state were included in the models to assess the % attenuation in estimates. RESULTS CD was associated with an increased risk of heart attack, angina pectoris, chronic bronchitis/emphysema/COPD, diabetes mellitus, hypothyroid/low metabolism, migraine, hypertension, and comorbidity (p < 0.05), independent of respondents' current psychological state. A sizeable proportion (23-42%) of the association between CD and physical health outcomes was driven by recall bias or mediation via respondents' current psychological state. Controlling for indicators of current psychological state reduced the strength of associations between CD and physical health outcomes; however, the independent associations remained in the same direction. CONCLUSION The association between retrospectively-reported CD and physical health outcomes in adulthood is not driven entirely by respondent's current psychological state.

Abstract
BACKGROUND Childhood early life stress (ELS) increases risk of adulthood major depressive disorder (MDD) and is associated with altered brain structure and function. It is unclear whether specific ELSs affect depression risk, cognitive function and brain structure. METHOD This cross-sectional study included 64 antidepressant-free depressed and 65 never-depressed individuals. Both groups reported a range of ELSs on the Early Life Stress Questionnaire, completed neuropsychological testing and 3T magnetic resonance imaging (MRI). Neuropsychological testing assessed domains of episodic memory, working memory, processing speed and executive function. MRI measures included cortical thickness and regional gray matter volumes, with a priori focus on the cingulate cortex, orbitofrontal cortex (OFC), amygdala, caudate and hippocampus. RESULTS Of 19 ELSs, only emotional abuse, sexual abuse and severe family conflict independently predicted adulthood MDD diagnosis. The effect of total ELS score differed between groups. Greater ELS exposure was associated with slower processing speed and smaller OFC volumes in depressed subjects, but faster speed and larger volumes in non-depressed subjects. In contrast, exposure to ELSs predictive of depression had similar effects in both diagnostic groups. Individuals reporting predictive ELSs exhibited poorer processing speed and working memory performance, smaller volumes of the lateral OFC and caudate, and decreased cortical thickness in multiple areas including the insula bilaterally. Predictive ELS exposure was also associated with smaller left hippocampal volume in depressed subjects. CONCLUSIONS Findings suggest an association between childhood trauma exposure and adulthood cognitive function and brain structure. These relationships appear to differ between individuals who do and do not develop depression.

Abstract
Autobiographical memory recall was investigated in two female adolescent groups; one group who had experienced a burn injury and a matched control group. The Burn group was not currently depressed or anxious, but scored significantly higher on the intrusion subscale of the impact of event scale compared to controls. Two autobiographical memory tasks, the autobiographical memory cueing task and the Children's Autobiographical Memory Inventory (CAMI), were used. For the cueing task, the Burn group was significantly slower to recall specific memories. This group also recalled significantly fewer specific memories and significantly more extended overgeneral memories. For the CAMI, the burns group produced significantly lower semantic and episodic recall. The Burn group also produced significant correlations between sub-scales of the impact of event scale and selected measures on the autobiographical memory tasks. Higher intrusion scores were associated with less detailed episodic recall. Higher avoidance scores were associated with longer latencies to recall memories to negative cue words and fewer specific memories to all cue words. These results are discussed from the perspective that the Burn group experienced intrusive thoughts which interfered with normal autobiographical functioning.

Abstract
Zusammenfassung. Die Validität des autobiographischen Gedächtnisses wird kontrovers diskutiert, bislang fehlen prospektive Längsschnittstudien weitgehend. Die vorliegende Studie überprüft die Validität des autobiographischen Gedächtnisses anhand der Daten einer prospektiven epidemiologischen Längsschnittstudie, die in vier Untersuchungswellen 399 achtjährige Kinder bis zum Alter von 25 Jahren begleitete. Im Alter von 25 Jahren wurden die Erinnerungsleistungen der Probanden an Kernfakten, Erziehungsstil der Eltern, eigene psychische Probleme sowie Lebensereignisse aus Kindheit und Jugend mit Hilfe eines voll strukturierten Fragebogens erhoben. Mit Ausnahme der Kernfakten waren die Erinnerungsleistungen durchweg schlecht, intelligente Probanden zeigten insgesamt bessere Erinnerungsleistungen, junge Erwachsene mit psychischen Störungen berichteten vermehrt auch früher nicht vorhandene Symptome. Die retrospektive Erfassung früherer Lebensereignisse, der Beziehung zu den Eltern und psychischer Auffälligkeiten im Rahmen von Risikostudien und klinischen Studien ist sehr bedenklich.

Abstract
Several clinicians who work with traumatized children have noted that these children exhibit a poor autobiographical memory. The present study was a first attempt to subject this clinical impression to formal testing. Memory for autobiographical facts (i.e., semantic autobiographical memory) was assessed in 10 adolescents with an alleged history of trauma and 17 adolescents without such a background. Results suggest that traumatized adolescents, indeed, have more difficulty with semantic personal memory than non-traumatized adolescents. Implications of the present findings for future research on trauma and autobiographical memory in children and adolescents are discussed.

Abstract
OBJECTIVE The aim of this paper is to develop an aetiological model for borderline personality disorder. METHOD The postulates of Hughlings Jackson are used to provide a preliminary explanatory framework for borderline phenomena. As a necessary background to this discussion, the findings concerning abuse in the early history of borderline personality disorder (BPD) and other conditions, notably somatisation disorder and dissociative states, are briefly reviewed. Other data, including family studies, which might have significance in the aetiology of BPD are also reviewed. RESULTS The hypothesis is put forward that the symptoms of BPD are due to the failure of 'experience-dependent' maturation of a cascade of neural networks, with prefrontal connections, which become active relatively late in development and which coordinate disparate elements of central nervous system function. These networks subserve higher psychological functions, including attentional focus and affect regulation. They also underpin the reflective function necessary to the emergence of self as the stream of consciousness, which appears at about the age of 4 years. CONCLUSION Adverse developmental circumstances may produce an interrelated set of symptom clusters, with associated neural network disturbances that are amenable to investigation with psychometric and brain imaging techniques. Since these disturbances are seen as 'experience-dependent', they are considered reversible, at least in part.

Abstract
Especially in the field of memory encoding and retrieval, the results of functional neuroimaging have provided new insights in anatomico-functional interactions. In particular this holds true for the role of the prefrontal cortex in mnestic information processing, for the contribution and participation of the two hemispheres in various processes of information transmission, and for views on disturbed information processing after organically obvious and so-called psychogenic forms of memory impairments. This report particularly stresses the insights obtained by functional neuroimaging for probably environmentally triggered deficiencies in memory processing and discusses possible subtle neuroanatomical correlates of functional amnesias. It is especially emphasised that stress conditions and depressive states may modify the release of steroids (glucocorticoids) and transmitter agonists at the brain level with the consequence of selective memory disturbances which may manifest as a "mnestic block syndrome".

Abstract
Recent findings from cognitive neuroscience and cognitive psychology may help explain why recovered memories of trauma are sometimes illusory. In particular, the notion of defective source monitoring has been used to explain a wide range of recently established memory distortions and illusions. Conversely, the results of a number of studies may potentially be relevant to forgetting and recovery of accurate memories, including studies demonstrating reduced hippocampal volume in survivors of sexual abuse, and recovery from functional and organic retrograde amnesia. Other recent findings of interest include the possibility that state-dependent memory could be induced by stress-related hormones, new pharmacological models of dissociative states, and evidence for 'repression' in patients with right parietal brain damage.
