Abstract
Neuroimaging studies of mood disorders demonstrate abnormalities in brain regions implicated in reward processing. However, there is a paucity of research investigating how social rewards affect reward circuit activity in these disorders. Here, we evaluated the relationship of both diagnostic category and dimensional depression severity to reward system function in bipolar and unipolar depression. In total, 86 adults were included, including 24 patients with bipolar depression, 24 patients with unipolar depression, and 38 healthy comparison subjects. Participants completed a social reward task during 3T BOLD fMRI. On average, diagnostic groups did not differ in activation to social reward. However, greater depression severity significantly correlated with reduced bilateral ventral striatum activation to social reward in the bipolar depressed group, but not the unipolar depressed group. In addition, decreased left orbitofrontal cortical activation correlated with more severe symptoms in bipolar depression, but not unipolar depression. These differential dimensional effects resulted in a significant voxelwise group by depression severity interaction. Taken together, these results provide initial evidence that deficits in social reward processing are differentially related to depression severity in the two disorders.

Abstract
Ziprasidone (Geodon) is a relatively new atypical antipsychotic medication with a unique pharmacological profile. It is indicated for the treatment of schizophrenia, but has also often been used off-label for other uses. This review summarizes its important properties, specifically the pharmacodynamic parameters, receptor-binding profile and relevance to clinical outcomes, side effects, and potential for drug-drug interactions and established clinical indications. Novel therapeutic applications and relevant clinical trials or reports are also examined. The authors review the current market and speculate on likely changes in 5 years.

Abstract
Premenstrual dysphoric disorder (PMDD) can occur co-morbidly with other axis I disorders, particularly mood and anxiety disorders. The data supporting this diagnostic dilemma are reviewed in terms of methodological comparisons between studies. The point prevalence of the co-occurrence of PMDD and other psychiatric disorders is discussed as well as implications for treatment and further study.
