“…This was not found to be the case in this study, which is in contrast with statements by some researchers suggesting that dissociation is related to memory distortion (e.g., Candel et al, 2003;Giesbrecht, Geraerts, & Merckelbach, 2007;Wright & LivingstonRaper, 2002) but is consistent with a more recent review (Dalenberg et al, 2012).…”

The misinformation effect is defined as an impairment in memory for past events due to exposure to misleading information (E. F. Loftus, 2005 ). Some people may be more susceptible to the misinformation effect than others, and this may also depend on their response to a distressing event. The purpose of the current study was to investigate several key factors that may contribute to misinformation susceptibility for distressing events, namely posttraumatic stress disorder symptoms such as avoidance, intrusions, and dissociation. Participants watched either a neutral or trauma film, rated their level of distress, and completed measures of trait and state dissociation. When participants returned a week later, misinformation was introduced via an eyewitness statement and free recall was assessed. Findings indicated that dissociation was related to higher distress ratings following the film but was not related to acceptance of misinformation. However, avoidance scores were related to increased recall of misinformation items, and reported experiences of intrusions were related to greater accuracy. These results are discussed in light of the paradoxical negative emotion hypothesis.

“…In the study by Kollins et al [250], significant associations were identified between CPT commission errors and SNPs in the DRD2 gene (rs2075654, rs1079596), and between reaction time variability and a SNP in the NET gene (rs3785155). Errors of commission occurred when subjects answered a question incorrectly; a pattern of heightened emotional reactivity and commission errors is typical for individuals with elevated dissociation scores [251]. On the other hand, Hess et al [252] carried out association tests with DBH genotypes on four independent samples: healthy volunteers (n=387), patients presenting affective disorders (n=182), adult ADHD patients (n=407), and patients presenting personality disorders (n=637).…”

Heterogeneity in attention-deficit/hyperactivity disorder (ADHD), with complex interactive operations of genetic and environmental factors, is expressed in a variety of disorder manifestations: severity, co-morbidities of symptoms, and the effects of genes on phenotypes. Neurodevelopmental influences of genomic imprinting have set the stage for the structuralphysiological variations that modulate the cognitive, affective, and pathophysiological domains of ADHD. The relative contributions of genetic and environmental factors provide rapidly proliferating insights into the developmental trajectory of the condition, both structurally and functionally. Parent-of-origin effects seem to support the notion that genetic risks for disease process debut often interact with the social environment, i.e., the parental environment in infants and young children. The notion of endophenotypes, markers of an underlying liability to the disorder, may facilitate detection of genetic risks relative to a complex clinical disorder. Simple genetic association has proven insufficient to explain the spectrum of ADHD. At a primary level of analysis, the consideration of epigenetic regulation of brain signalling mechanisms, dopamine, serotonin, and noradrenaline is examined. Neurotrophic factors that participate in the neurogenesis, survival, and functional maintenance of brain systems, are involved in neuroplasticity alterations underlying brain disorders, and are implicated in the genetic predisposition to ADHD, but not obviously, nor in a simple or straightforward fashion. In the context of intervention, genetic linkage studies of ADHD pharmacological intervention have demonstrated that associations have fitted the "drug response phenotype," rather than the disorder diagnosis. Despite conflicting evidence for the existence, or not, of genetic associations between disorder diagnosis and genes regulating the structure and function of neurotransmitters and brainderived neurotrophic factor (BDNF), associations between symptoms-profiles endophenotypes and single nucleotide polymorphisms appear reassuring.

“…Previous studies detected in individuals with BPD an autonomic imbalance in provocation studies (Austin et al, 2007;Dixon-Gordon, Yiu, & Chapman, 2013;Giesbrecht, Geraerts, & Merckelbach, 2007). To our knowledge, few studies have assessed HRV in persons with DD, especially in stressful conditions (for a review, see van der Kruijs et al, 2012).…”

The aim of this study was to assess heart rate variability (HRV) in individuals with dissociative disorders (DD) before and after the Adult Attachment Interview (AAI). Electrocardiograms were recorded before, during, and after the AAI in 13 individuals with DD and 13 healthy participants matched for age and gender. Significant change in HRV was observed only in the DD group. After the AAI, those with DD showed significant increases in the low frequency/high frequency ratio (pre-AAI = 1.91 ± 1.19; post-AAI = 4.03 ± 2.40; Wilcoxon test = -2.76, p = .005). Our results suggest that the retrieval of childhood attachment experiences in individuals with DD is associated with a change in HRV patterns that could reflect the emotion dysregulation of dissociative psychopathological processes.
