Attentional control abnormalities in posttraumatic stress disorder: Functional, behavioral, and structural correlates

Attentional bias and attentional control in Posttraumatic Stress Disorder.

Extensive evidence exists for an association between attentional bias (AB; attentional vigilance or avoidance) and anxiety. Recent studies in healthy participants suggest that attentional control (AC) may facilitate inhibition of automatic attentional processes associated with anxiety. To investigate relationships among AC, trauma-related AB, symptom severity and trait anxiety in patients with ...

Structural brain abnormalities common to posttraumatic stress disorder and depression.

BACKGROUND Posttraumatic stress disorder (PTSD) and major depression are reliably associated with reductions in brain volume in markedly similar areas. To our knowledge, no volumetric studies have directly contrasted these conditions. We investigated which, if any, grey matter reductions would be uniquely associated with each disorder. We also investigated more subtle independent effects: speci...

Cognitive abnormalities in posttraumatic stress disorder.

PURPOSE OF REVIEW The current review aims to describe and evaluate research on cognitive difficulties associated with posttraumatic stress disorder (PTSD) published between January 2007 and June 2008.

Relationship between structural abnormalities in the cerebellum and dementia, posttraumatic stress disorder and bipolar disorder

New evidence suggests that the cerebellum has structural and functional abnormalities in psychiatric disorders. Objective In this research, the goal was to measure the volume of the cerebellum and its subregions in individuals with psychiatric disorders and to relate these findings to their symptoms. Methods Patients with different degrees of cognitive impairment (Epidemiology of the Elderl...
