Classical conditioning features prominently in many etiological accounts of panic disorder. According to such accounts, neutral conditioned stimuli present during panic attacks acquire panicogenic properties. Conditioned stimuli triggering panic symptoms are not limited to the original conditioned stimuli but are thought to generalize to stimuli resembling those co-occurring with panic, resulting in the proliferation of panic cues. The authors conducted a laboratory-based assessment of this potential correlate of panic disorder by testing the degree to which panic patients and healthy subjects manifest generalization of conditioned fear. ⋯ The findings demonstrate a marked proclivity toward fear overgeneralization in panic disorder and provide a methodology for laboratory-based investigations of this central, yet understudied, conditioning correlate of panic. Given the putative molecular basis of fear conditioning, these results may have implications for novel treatments and prevention in panic disorder.

Risks for depression onset in primary care elderly patients: potential targets for preventive interventions.
Prevention of late-life depression, a common, disabling condition with often poor outcomes in primary care, requires identification of seniors at highest risk of incident episodes. The authors examined a broad range of clinical, functional, and psychosocial predictors of incident depressive episodes in a well-characterized cohort of older primary care patients. ⋯ Indicators routinely assessed in primary care identified a group at very high risk for onset of major depressive episodes. Such markers may inform current clinical care by fostering the early detection and intervention critical to improving patient outcomes and may serve as the basis for future studies refining the recommendations for screening and determining the effectiveness of preventive interventions.

Case Reports Randomized Controlled Trial Comparative Study
Enhancing multiyear guideline concordance for bipolar disorder through collaborative care.
Implementation of evidence-based care for serious mental illnesses such as bipolar disorder has been suboptimal. Improving and sustaining concordance with clinical practice guidelines has been a cornerstone of efforts to enhance evidence-based care and improve outcomes. For bipolar disorder, however, there has been only one regional controlled trial reporting guideline concordance, and no data are available for time periods longer than 1 year. In a multiregion effectiveness trial in veterans with bipolar disorder, the authors assessed the effects of a collaborative care model for this disorder on guideline concordance in care over a 3-year period. ⋯ Multicomponent collaborative care models, which include not only provider support for guideline implementation but also patient self-management skill enhancement and facilitated treatment access and continuity, can improve guideline concordance over the long term, even in severely impaired patients.
