Gregory and colleagues conducted a cross-sectional case-control structural magnetic resonance imaging study of 66 men to identify structural gray matter differences between persistent violent offenders who meet criteria for antisocial personality disorder and the syndrome of psychopathy and those meeting criteria only for ASPD.

To contrast changes in brain activation related to symptomatic improvement with use of the stimulant methylphenidate vs the nonstimulant atomoxetine, Schulz and coauthors recruited 36 youth with attention-deficit/hyperactivity disorder who underwent functional magnetic resonance imaging from randomized clinical trials.

Tromp et al investigated structural connectivity between ventral prefrontal cortex or anterior cingulate cortex areas and the amygdala in GAD and assessed associations with functional connectivity between those areas. Fractional anisotropy values in the uncinate fasciculus were measured by tract-based analysis for diffusion-tensor imaging data.
