Mol Psychiatry
. 2024 Jan;
29(3):611-623.
PMID: 38195980
Although the cerebellum contributes to higher-order cognitive and emotional functions relevant to posttraumatic stress disorder (PTSD), prior research on cerebellar volume in PTSD is scant, particularly when considering subregions that...

. 2023 Nov;
49(3):609-619.
PMID: 38017161
Posttraumatic stress disorder (PTSD) is associated with lower cortical thickness (CT) in prefrontal, cingulate, and insular cortices in diverse trauma-affected samples. However, some studies have failed to detect differences between...

BJPsych Open
. 2023 May;
9(3):e78.
PMID: 37128866
Background: There is limited experimentally controlled neuroimaging research available that could explain how dissociative states occur and which neurobiological changes are involved in acute post-traumatic dissociation. Aims: To test the...

Neuroimage
. 2022 Aug;
261:119509.
PMID: 35917919
Results of neuroimaging datasets aggregated from multiple sites may be biased by site-specific profiles in participants' demographic and clinical characteristics, as well as MRI acquisition protocols and scanning platforms. We...

BJPsych Open
. 2022 Jun;
8(4):e109.
PMID: 35686464
Background: Current neurobiological models of post-traumatic stress disorder (PTSD) assume excessive medial frontal activation and hypoactivation of cortico-limbic regions as neural markers of post-traumatic dissociation. Script-driven imagery is an established...

Biol Psychiatry Cogn Neurosci Neuroimaging
. 2022 Mar;
7(9):935-948.
PMID: 35307575
Background: Posttraumatic stress disorder (PTSD) is accompanied by disrupted cortical neuroanatomy. We investigated alteration in covariance of structural networks associated with PTSD in regions that demonstrate the case-control differences in...

Brain Behav
. 2021 Dec;
12(1):e2413.
PMID: 34907666
Background: Posttraumatic stress disorder (PTSD) is associated with markers of accelerated aging. Estimates of brain age, compared to chronological age, may clarify the effects of PTSD on the brain and...

Eur J Psychotraumatol
. 2021 Aug;
12(1):1929025.
PMID: 34394855
Background: Meta-analytic results indicate that posttraumatic stress disorder (PTSD) is associated with hypoactivation of the medial prefrontal cortex (mPFC), hyperactivation of the amygdala, and volume reductions of the hippocampus. Effective...
