The second-generation antidepressants (SGAs) are used widely in patients with Alzheimer's disease (AD) for the treatment of mood disorder, sleep disturbance and psychiatric symptoms. Several evidences from AD mice confirmed that antidepressants could delaying cognitive decline. However, the conclusions varied in randomized controlled trials (RCTs) based on patients. This meta-analysis summarizes the cognitive impact of SGAs on AD patients with different neuropsychiatric symptoms (NPS). Results show there is no effect on cognition and depression between SGAs treatment and controls, and this remains in subgroups analyses of duration of medication (<12 weeks or ≥12 weeks), drug classes (SSRIs or non-SSRIs), combination with anti-dementia medication, various NPS, and degree of AD. The available evidence provides no support for the efficacy of SGAs for cognition and depression of AD patients. The implications of the findings and their mechanism relevance are also discussed in this paper.

Background: Although there is clear evidence that therapeutic drug monitoring (TDM) has beneficial effects for patients treated with tricyclic antidepressants, it is generally not recommended for second-generation antidepressants (SGA). However, it has been suggested that methodological shortcomings might influence the results in TDM studies with SGA.
Aim: A qualitative assessment of randomized controlled trials (RCTs) that specifically investigated drug concentration-effect relationships of SGA in patients with major depressive disorder (MDD) to analyze the potential benefit of TDM during treatment with these agents.

Bipolar disorder is a chronic disease that imposes a lifelong burden on those that suffer from it. Lithium is still considered both gold standard treatment and first-line maintenance treatment, and access to treatment with lithium is paramount to improving patient outcomes. However, access to adequate treatment is not only contingent on symptom recognition, accurate diagnosis, and individualization of treatment, but also affected by racial and ethnic disparities at each stage of patient experience.
