Current results suggest that generalized, rather than specific, cognitive impairment characterizes euthymic bipolar disorder. Age, illness duration, education, and clinical course may moderate these broad cognitive effects. Against this general impairment backdrop, there may be a relative preservation of crystallized verbal ability.

Subthreshold posttraumatic stress disorder (PTSD) is a chronic condition that is often ignored, the cumulative effects of which can negatively impact an individual's quality of life and overall health care costs. However, subthreshold PTSD prevalence rates and impairment remain unclear due to variations in research methodology. This study examined the existing literature in order to recommend approaches to standardize subthreshold PTSD assessment. We conducted (a) a meta-analysis of subthreshold PTSD prevalence rates and (b) compared functional impairment associated with the 3 most commonly studied subthreshold PTSD definitions. Meta-analytic results revealed that the average prevalence rate of subthreshold PTSD across studies was 14.7%, with a lower rate (12.6%) among the most methodologically rigorous studies and higher rate (15.6%) across less rigorous studies. There were significant methodological differences among reviewed studies with regard to definition, measurement, and population. Different definitions led to prevalence rates ranging between 13.7% and 16.4%. Variability in prevalence rates most related to population and sample composition, with trauma type and community (vs. epidemiological) samples significantly impacting heterogeneity. Qualitative information gathered from studies presenting functional correlates supported current evidence that psychological and behavioral parameters were worse among subthreshold PTSD groups compared with no-PTSD groups, but not as severe as impairment in PTSD groups. Several studies also reported significant increased risk of suicidality and hopelessness as well as higher health care utilization rates among those with subthreshold PTSD (compared with trauma exposed no-PTSD samples). Based on findings, we propose recommendations for developing a standard approach to evaluation of subthreshold PTSD.

Few studies have evaluated interventions addressing 1 or more CVD risk factors in people with serious mental illness. Glucose- and lipid-related results were mainly reported as secondary outcome assessments in studies of weight-management interventions. Comparative effectiveness studies are needed to test multimodal strategies, agents known to be effective in nonserious mental illness populations, and antipsychotic-management strategies.
