Major depressive disorder (MDD) is accompanied by atypical brain structure affecting grey and white matter from the early stages. Neuroimaging studies of first-episode depression (FED) have provided evidence on this regard, but most of the studies are cross-sectional. The aim of this longitudinal study was to test potential changes in grey matter (GM) and white matter (WM) volumes in FED. ⋯ The present findings provided some new evidence of the role of white matter alterations in the early stages of MDD and in the progression of the illness.

Mood disorders are major risk factors for suicidal behavior. While cross-sectional studies implicate frontal systems, data to aid prediction of suicide-related behavior in mood disorders are limited. Longitudinal research on neuroanatomical mechanisms underlying suicide risk may assist in developing targeted interventions. Therefore, we conducted a preliminary study investigating baseline gray and white matter structure and longitudinal structural changes associated with future suicide attempts. ⋯ Results suggest abnormalities of gray and white matter in frontal systems and differences in developmental changes of frontal white matter may increase risk of suicide-related behavior in youths with mood disorders. Findings provide potential new leads for early intervention and prevention strategies.

Depressive and anxiety disorders are highly prevalent and detrimental in primary care settings. However, there are gaps in the literature concerning effectiveness and generalizability of empirically supported interventions and treatment of both depression and anxiety in primary care settings. The aim of this review is to systematically assess and meta-analyze the effectiveness of brief empirically-supported psychotherapies for treating depression and/or anxiety in primary care. ⋯ Treatment effects were found for CBT and PST, both for depressive and anxiety disorders. Interventions delivered outside primary care settings were more effective than those within, individual treatment had greater treatment effects compared to group treatment, and both technology-assisted and in-person treatments were found to be effective.

Depression and anxiety are common during the antenatal and postnatal period, and are known to have a significant impact on the woman and her unborn infant. Pregnant women state a preference for non-pharmacological treatment options, and use complementary medicines and therapies to manage these symptoms. We examined the effectiveness and safety of these modalities on depression and anxiety during pregnancy. ⋯ Acupuncture, bright light therapy, and massage may reduce antenatal depression. There is a need for high quality and larger studies that include postnatal follow up and maternal and neonatal outcomes.

Findings regarding brain circuitry abnormalities in suicide attempters (SAs) converge across bipolar disorder (BD) and major depressive disorder (MDD), the most common disorders observed in suicides. These abnormalities appear to be present during adolescence/young adulthood when suicide rates increase steeply, and suicide is a leading cause of death in this age group. Identification of brain circuitry common to adolescent/young adult SAs with BD and MDD is important for generating widely effective early prevention strategies. We examined brain circuitry in SAs in adolescents/young adults across these two disorders. ⋯ Common fronto-limbic gray and white matter alterations in adolescent/young adult SAs are potential targets for suicide prevention strategies across mood disorders. Preliminary findings of disorder-specific regional findings could suggest diagnostic-specific optimal targets may exist.
