The primary aim of this functional magnetic resonance imaging (fMRI) study was to test the utility of a paced motor activation task to evaluate frontal-subcortical (FSC) circuit function in bipolar depression. A secondary aim was to determine if utilizing both a motor and cognitive activation paradigm (Stroop) would provide information about the potential(More)
BACKGROUND Compelling evidence suggests abnormal functioning of frontal-subcortical (FSC) circuits in bipolar disorder, but it is unknown whether these are state or trait abnormalities. Longitudinal functional neuroimaging studies may help clarify this issue. However, studies to date have not determined which activation paradigms may be most useful for this(More)
conditions.1,2 For the unipolar disorders— major depression and dysthymic disorder— the mood change is toward one pole of the affective spectrum. For the bipolar conditions—bipolar I disorder, bipolar II disorder, and cyclothymic disorder— the mood changes are toward both ends of the mood spectrum, involving both depressed and manic episodes. Mood disorders(More)
We used a functional magnetic resonance imaging motor activation paradigm for both hands and functional connectivity analyses to investigate motor deactivation. These analyses revealed ipsilateral (to the task) postcentral gyrus connectivity with the ipsilateral primary motor cortex as well as contralateral cerebellum for both hands. Analyses using(More)
The frontal–subcortical skeletomotor circuit is thought to be a motor processing network. However, the exact function of the circuit is poorly characterized. This fMRI study utilized a motor activation paradigm for both hands to probe circuit engagement and connectivity. Activation of the circuit decreased over time for the right hand, which suggests(More)
OBJECTIVE This study aimed to increase the understanding of the clinical characteristics and utilization of health services among veterans with comorbid bipolar disorder and posttraumatic stress disorder (PTSD). METHODS A retrospective chart review was conducted that examined the clinical and health service use data of 139 male veterans with bipolar(More)
