Altered resting-state functional connectivity of basolateral and centromedial amygdala complexes in posttraumatic stress disorder.
(Neuropsychopharmacology, 2014-01)The amygdala is a major structure that orchestrates defensive reactions to environmental threats and is implicated in hypervigilance and symptoms of heightened arousal in posttraumatic stress disorder (PTSD). The basolateral ... -
Amygdala volume changes in posttraumatic stress disorder in a large case-controlled veterans group.
(Arch Gen Psychiatry, 2012-11)CONTEXT: Smaller hippocampal volumes are well established in posttraumatic stress disorder (PTSD), but the relatively few studies of amygdala volume in PTSD have produced equivocal results. OBJECTIVE: To assess a large cohort ... -
Amygdala, Hippocampus, and Ventral Medial Prefrontal Cortex Volumes Differ in Maltreated Youth with and without Chronic Posttraumatic Stress Disorder.
(Neuropsychopharmacology, 2016-02)Posttraumatic stress disorder (PTSD) is considered a disorder of recovery where individuals fail to learn and retain extinction of the traumatic fear response. In maltreated youth, PTSD is common, chronic, and associated ... -
Effects of chronic mild traumatic brain injury on white matter integrity in iraq and afghanistan war veterans
(Human Brain Mapping, 2013-11-01)Mild traumatic brain injury (TBI) is a common source of morbidity from the wars in Iraq and Afghanistan. With no overt lesions on structural MRI, diagnosis of chronic mild TBI in military veterans relies on obtaining an ... -

Fear learning circuitry is biased toward generalization of fear associations in posttraumatic stress disorder.
(Transl Psychiatry, 2015-12-15)Fear conditioning is an established model for investigating posttraumatic stress disorder (PTSD). However, symptom triggers may vaguely resemble the initial traumatic event, differing on a variety of sensory and affective ... -

White Matter Changes Related to Subconcussive Impact Frequency during a Single Season of High School Football.
(AJNR Am J Neuroradiol, 2017-12-21)BACKGROUND AND PURPOSE: The effect of exposing the developing brain of a high school football player to subconcussive impacts during a single season is unknown. The purpose of this pilot study was to use diffusion tensor ... -
White matter compromise in veterans exposed to primary blast forces
(Journal of Head Trauma Rehabilitation, 2015)OBJECTIVE:: Use diffusion tensor imaging to investigate white matter alterations associated with blast exposure with or without acute symptoms of traumatic brain injury (TBI). PARTICIPANTS:: Forty-five veterans of the recent ... -
