Although many branded and generic antidepressants are approved for the treatment of major depressive disorder (MDD) in Canada, efficacy and tolerability differ among patients, and new treatment options are needed. Symptom types (eg, fatigue, energy/motivation, cognition, and functioning), medication type, treatment duration, and the need for maintenance therapy are factors that may influence treatment effectiveness. Three antidepressants, vortioxetine, levomilnacipran extended-release (ER), and vilazodone have recently become available in Canada...

Major depressive disorder (MDD) is the leading cause of disability worldwide with a heterogeneous symptom profile. Levomilnacipran extended release (ER) (Fetzima), a SNRI, has been approved by the Food and Drug Administration for treatment of MDD. While categorized as a SNRI, in contradistinction to other approved SNRIs, levomilnacipran exhibits differential affinity for the norepinephrine reuptake transporter when compared to the serotonin reuptake transporter. Areas covered: Completed clinical trials which focused on levomilnacipran ER administered in those with MDD were included in this drug evaluation...

Major depressive disorder (MDD) is highly prevalent, recurrent, and associated with functional impairment, morbidity, and mortality. Herein, we aimed to identify disruptions in functional connectomics among subjects with MDD by using resting-state functional magnetic resonance imaging (rs-fMRI). Sixteen subjects with MDD and thirty health controls completed resting-state fMRI scans and clinical assessments (e.g., Hamilton Depression Rating Scale (HAMD) and Hospital Anxiety and Depression Scale (HADS)). We found higher amplitude of low frequency fluctuations (ALFF) bilaterally in the hippocampus and amygdala among MDD subjects when compared to healthy controls...

INTRODUCTION: Work-related disability and productivity loss in Major Depressive Disorder (MDD) are critical determinants of patient quality of life and contribute significantly to the human and economic costs of MDD. Notwithstanding the return to work and pre-morbid levels of functioning as a critical therapeutic objective among individuals with MDD, it is unclear whether antidepressant treatment significantly and reliably improves measures of workplace functioning. Herein, we investigate to what extent antidepressant treatment improves workplace functioning among adults with MDD...

Bipolar disorder (BD) is strongly associated with immune dysfunction. Replicated epidemiological studies have demonstrated that BD has high rates of inflammatory medical comorbidities, including autoimmune disorders, chronic infections, cardiovascular disease and metabolic disorders. Cytokine studies have demonstrated that BD is associated with chronic low-grade inflammation with further increases in pro-inflammatory cytokine levels during mood episodes. Several mechanisms have been identified to explain the bidirectional relationship between BD and immune dysfunction...

Major depressive disorder (MDD) is an often chronic and recurring illness. Left untreated, MDD may result in progressive alterations in brain morphometry and circuit function. Recent findings, however, suggest that pharmacotherapy may halt and possibly reverse those effects. These findings, together with evidence that a delay in treatment is associated with poorer clinical outcomes, underscore the urgency of rapidly treating depression to full recovery. Early optimized treatment, using measurement-based care and customizing treatment to the individual patient, may afford the best possible outcomes for each patient...

​​ Many patients with mood disorders do not experience pure episodes of depression or mania. Rather, these individuals experience mixed presentations. In the past, individuals experiencing mixed mood episodes were often misdiagnosed due to overly strict diagnostic criteria, leading to poor outcomes and treatment response. The addition of the mixed features specifier to the DSM-5 holds promise for improving recognition in patients who may be experiencing mixed symptoms. Furthermore, awareness has grown important warning signs that should be considered risk factors for progression to bipolar disorder and should warrant special clinical attention...
