Journal ArticleDOI
Emotion Modulation in PTSD: Clinical and Neurobiological Evidence for a Dissociative Subtype
Ruth A. Lanius,Eric Vermetten,Richard J. Loewenstein,Bethany Brand,Christian Schmahl,J. Douglas Bremner,David Spiegel +6 more
TL;DR: The neural manifestations of the dissociative subtype in PTSD are compared to those underlying the reexperiencing/hyperaroused subtype and have important implications for treatment of PTSD, including the need to assess patients with PTSD for Dissociative symptoms and to incorporate the treatment of dissociatives symptoms into stage-oriented trauma treatment.
Journal ArticleDOI
Spontaneous Low-Frequency Fluctuations in the BOLD Signal in Schizophrenic Patients: Anomalies in the Default Network
Robyn Bluhm,Jodi Miller,Ruth A. Lanius,Elizabeth A. Osuch,Kristine Boksman,Richard W. J. Neufeld,Jean Théberge,Betsy Schaefer,Peter C. Williamson +8 more
TL;DR: Data from this study suggest significant abnormalities in resting-state neural networks in schizophrenia, and further investigations of spontaneous slow fluctuations of the BOLD signal seem warranted in this population.
Journal ArticleDOI
Neural Correlates of Traumatic Memories in Posttraumatic Stress Disorder: A Functional MRI Investigation
Ruth A. Lanius,Peter C. Williamson,Maria Densmore,Kristine Boksman,Madhulika A. Gupta,Richard W. J. Neufeld,Joseph S. Gati,Ravi S. Menon +7 more
TL;DR: The findings suggest anterior cingulate, frontal, and thalamic involvement in the neuronal circuitry underlying PTSD.
Journal ArticleDOI
Brain activation during script-driven imagery induced dissociative responses in PTSD: a functional magnetic resonance imaging investigation.
Ruth A. Lanius,Peter C. Williamson,Kristine Boksman,Maria Densmore,Madhulika A. Gupta,Richard W. J. Neufeld,Joseph S. Gati,Ravi S. Menon,Ravi S. Menon +8 more
TL;DR: Differences observed clinically, psychophysiologically, and neurobiologically between patients who respond to traumatic script-driven imagery with dissociative versus nondissociative responses may suggest different neuronal mechanisms underlying these two distinct reactions.
Journal Article
Alterations in default network connectivity in posttraumatic stress disorder related to early-life trauma.
Robyn Bluhm,Peter C. Williamson,Elizabeth A. Osuch,Paul A. Frewen,Todd K. Stevens,Kristine Boksman,Richard W. J. Neufeld,Jean Théberge,Ruth A. Lanius +8 more
TL;DR: Spontaneous activity in the default network during rest, as measured using PCC correlations, is altered in patients with PTSD, and the observed alterations may be associated with the disturbances in self-referential processing often observed in Patients with chronic PTSD related to early-life trauma.
