Advances in Mood Disorder Pharmacotherapy: Evaluating New Antipsychotics and Mood Stabilizers for Bipolar Disorder and Schizophrenia

This article provides a narrative review of recent developments in mood-stabilizing drugs, considering their mechanism of action, efficacy, safety, and therapeutic potential in the treatment of mood disorders, particularly bipolar disorder and schizophrenia. The review focuses on the mechanism and clinical aspects of second-generation antipsychotic medications; aripiprazole, classified as a third-generation antipsychotic medication; lamotrigine, as a representative of antiepileptic drugs; and lurasidone, a novel second-generation antipsychotic medication. Moreover, the article refers to one of the newest and most highly effective normothymic drugs, cariprazine. The potential of new mood stabilizer candidates lumateperone and brexpiprazole is also presented. Covered topics include the clinical efficacy of new drugs in reducing manic and depressive symptoms during acute episodes, as well as their role in preventing relapse. In addition, we analyzed the incidence of adverse effects of each drug. Many of the new drugs have strong potential to be beneficial and safe in cases of many comorbidities, as they do not cause many adverse effects and do not require high doses of use. The results underscore the importance of ongoing and future research to better understand the action and efficacy of these mood stabilizers and their implications in the treatment of mood disorders, aiming to achieve euthymia and improve the quality of life of affected patients. In this article, we aim to review current drug treatments for the management of mood disorders, including bipolar disorder and schizophrenia.

Factors associated with suicide attempts in the antecedent illness trajectory of bipolar disorder and schizophrenia

BACKGROUND

Factors associated with suicide attempts during the antecedent illness trajectory of bipolar disorder (BD) and schizophrenia (SZ) are poorly understood.

METHODS

Utilizing the Rochester Epidemiology Project, individuals born after 1985 in Olmsted County, MN, presented with first episode mania (FEM) or psychosis (FEP), subsequently diagnosed with BD or SZ were identified. Patient demographics, suicidal ideation with plan, self-harm, suicide attempts, psychiatric hospitalizations, substance use, and childhood adversities were quantified using the electronic health record. Analyses pooled BD and SZ groups with a transdiagnostic approach given the two diseases were not yet differentiated. Factors associated with suicide attempts were examined using bivariate methods and multivariable logistic regression modeling.

RESULTS

A total of 205 individuals with FEM or FEP (BD = 74, SZ = 131) were included. Suicide attempts were identified in 39 (19%) patients. Those with suicide attempts during antecedent illness trajectory were more likely to be female, victims of domestic violence or bullying behavior, and have higher rates of psychiatric hospitalizations, suicidal ideation with plan and/or self-harm, as well as alcohol, drug, and nicotine use before FEM/FEP onset. Based on multivariable logistic regression, three factors remained independently associated with suicidal attempts: psychiatric hospitalization (OR = 5.84, 95% CI 2.09-16.33, p < 0.001), self-harm (OR = 3.46, 95% CI 1.29-9.30, p = 0.014), and nicotine use (OR = 3.02, 95% CI 1.17-7.76, p = 0.022).

CONCLUSION

Suicidal attempts were prevalent during the antecedents of BD and SZ and were associated with several risk factors before FEM/FEP. Their clinical recognition could contribute to improve early prediction and prevention of suicide during the antecedent illness trajectory of BD and SZ.
