Research suggests that responses to script-driven trauma imagery in posttraumatic stress disorder (PTSD) include reexperiencing and dissociative symptom subtypes. This functional magnetic resonance imaging (fMRI) study employed a dimensional approach characterizing responses, using the Responses Script-Driven Imagery Scale correlational analyses of relationships between severity state symptoms neural activation. As predicted, was associated positively with right anterior insula activity...
Abstract Neurofeedback has begun to attract the attention and scrutiny of scientific medical mainstream. Here, neurofeedback researchers present a consensus-derived checklist that aims improve reporting experimental design standards in field.
Amygdala dysregulation has been shown to be central the pathophysiology of posttraumatic stress disorder (PTSD) representing a critical treatment target. Here, amygdala downregulation was targeted using real-time fMRI neurofeedback (rt-fMRI-nf) in patients with PTSD, allowing us examine further regulation emotional states during symptom provocation. Patients (n = 10) completed three sessions rt-fMRI-nf instruction downregulate activation amygdala, while viewing personalized trauma words....
Neurofeedback (NFB) involves a brain-computer interface that allows users to learn voluntarily control their cortical oscillations, reflected in the electroencephalogram (EEG). Although NFB is being pioneered as noninvasive tool for treating brain disorders, there insufficient evidence on mechanism of its impact function. Furthermore, dominant rhythm human alpha oscillation (8-12 Hz), yet behavioral significance remains multifaceted and largely correlative. In this study with 34 healthy...
BackgroundThree intrinsic connectivity networks in the brain, namely central executive, salience, and default mode networks, have been identified as crucial to understanding of higher cognitive functioning, functioning these has suggested be impaired psychopathology, including posttraumatic stress disorder (PTSD).Objective1) To describe three main large-scale human brain; 2) discuss neural PTSD related symptoms; 3) offer hypotheses for neuroscientifically-informed interventions based on...
Background Dissociative symptoms are increasingly recognized in individuals with posttraumatic stress disorder (PTSD). The aim of this study was to investigate the prevalence derealization and depersonalization via latent profile analyses (LPAs) a civilian PTSD sample examine relationship between dissociative factor analytic methods. Methods A predominantly related childhood abuse (n = 134) completed diagnostic interview for comorbid psychiatric disorders. LPAs confirmatory (CFAs) were...
Individuals with posttraumatic stress disorder (PTSD) often exhibit deficits in emotional experience and expression, which suggests that certain individuals PTSD may be alexithymic. In this study, a sample of 105 PTSD, clinical correlates alexithymia included reexperiencing, hyperarousal, numbing, dissociative symptoms, retrospectively reported experiences childhood neglect. subsample 26 related to motor vehicle accident, functional neural responses trauma-script imagery were associated...
Objective Electroencephalographic ( EEG ) neurofeedback training has been shown to produce plastic modulations in salience network and default mode functional connectivity healthy individuals. In this study, we investigated whether a single session of aimed at the voluntary reduction alpha rhythm (8–12 Hz) amplitude would be related differences oscillations, MRI fMRI connectivity, subjective measures state anxiety arousal group individuals with post‐traumatic stress disorder (PTSD). Method...
Objective Post‐traumatic stress disorder (PTSD) is considered a multidimensional disorder, with distinct symptom clusters including re‐experiencing, avoidance/numbing, hyperarousal, and most recently depersonalization/derealization. However, the extent of differing intrinsic network connectivity underlying these symptoms has not been fully investigated. We therefore investigated degree association between resting salience (SN), default mode (DMN), central executive (CEN) networks PTSD...
This retrospective survey study compared the differential risk of lifetime traumatic stressors, so-called "non-traumatic stressors" experienced over past year, referring to life events that do not meet criteria for A1 events, and adverse childhood experiences (ACE) on severity DSM-5 versus ICD-11 PTSD, Complex PTSD (CPTSD), dissociative subtype (D-PTSD) symptoms among 418 participants recruited online. In pairwise analyses, all stress types were associated with outcomes. However, multiple...
