Dissociative symptoms may be the by-products of a labile sleep-wake cycle (Koffel and Watson, 2009a). This may help to explain why dissociation overlaps with fantasy proneness and cognitive failures. Using path analysis, we tested to what extent data gathered in a nonclinical, predominantly female sample (N=139) supported two conceptual models. The first model assumes that unusual sleep experie...

A task-switching paradigm was used to examine differences in attentional control across younger adults, middle-aged adults, healthy older adults, and individuals classified in the earliest detectable stage of Alzheimer's disease (AD). A large sample of participants (570) completed a switching task in which participants were cued to classify the letter (consonant/vowel) or number (odd/even) task...

AIM Dissociative symptoms are often found in psychiatric patients and have been implicated in psychotic trauma. We aimed to explore dissociative tendencies in psychiatric patients including dissociative disorders (DDs), obsessive-compulsive disorder (OCD), eating disorder (ED), and post-traumatic stress disorder (PTSD) by using the Dissociation Questionnaire Japanese version (DIS-Q-J). METHOD...

Electroconvulsive therapy (ECT) is increasingly used as a treatment for psychiatric disorders. Cardiac effects are the principal cause of medical complications in these patients. We report a case of atrioventricular (AV) dissociation that occurred after ECT that was treated with pacemaker implantation. The mechanisms contributing to the onset of AV dissociation in this patient, and the manageme...

OBJECTIVE To explore the role of trauma and dissociation over self-injurious behaviors (SIB) and suicide attempts (SA) in adolescents. METHODS A total of 207 adolescents participated in the study. After conducting diagnostic interview, participants were divided into five groups as subjects with dissociative disorders (DD), attention deficit hyperactivity disorder (ADHD), major depressive diso...

Dissociation is a failure of perceptual, memorial and emotional integration that is associated with a variety of psychiatric disorders. Dissociative processes are usually attributed to the sequelae of childhood trauma although there are data to suggest that genetic influences are also important. Bipolar disorder (BD), a condition with a strong genetic basis, has also been associated with early ...

OBJECTIVES The aim of the study was to analyze relationships between the variables: severity of depression symptoms, feelings towards one's own body, dissociation, the number and type of traumatic life events experienced by adolescents who engage in deliberate self-injury and are psychiatrically hospitalized. METHODS We examined 60 patients aged 13-17 (M = 15.48, SD = 1.19). More than a half ...

The theory of structural dissociation of the personality proposes that patients with complex trauma-related disorders are characterized by a division of their personality into different prototypical parts, each with its own psychobiological underpinnings. As one or more apparently normal parts (ANPs), patients have a propensity toward engaging in evolutionary prepared action systems for adaptat...
