Background: Major depressive episodes with psychotic features are more common in bipolar disorder than in major depressive disorder; however, there is little information on the optimal treatment for bipolar depression with psychotic features.

Case Presentation: The patient was a 69-year-old man. At the age of 66, he was admitted to the hospital for the treatment of bipolar depression with psychotic features. He was treated with a combination therapy of antipsychotics and antidepressants during long-term hospitalization. At the age of 69, he relapsed and was admitted to the hospital again. He was initially treated with olanzapine and lithium for the treatment of bipolar depression with psychotic features. He partially responded to the combination therapy, and psychomotor retardation and delusion of guilt disappeared; however, he developed psychomotor agitation and delusion of persecution, which was a mood-incongruent psychotic feature. Finally, he fully recovered with an additional dosage of lamotrigine, and had no experience of relapse after discontinuation of olanzapine.

Conclusions: This case report implicates the utility of lamotrigine for bipolar depression with psychotic features, and further studies are needed to establish the optimal treatment.

Understanding the neural mechanisms underlying BD is critical for improving diagnostic accuracy and developing more effective treatments. This study utilized resting-state functional magnetic resonance imaging (rs-fMRI) to investigate functional connectivity within the ventral and dorsal attention networks in 52 patients with BD and 51 healthy controls.

Introduction Psychoeducation is a form of psychosocial treatment with proven efficacy in preventing the relapse of bipolar disorder (BD). However, the effectiveness of psychoeducation has not been verified in Japan. We aimed to examine the effect of a brief group psychoeducation course (eight-session long) on relapse prevention in Japanese patients with BD and associated factors.

Background: Atypical antipsychotics are a common treatment for serious mental illness, but many are associated with adverse effects, including weight gain and cardiovascular issues, and real-world experience may differ from clinical trial data. Cariprazine has previously demonstrated a favorable safety and tolerability profile in clinical trials. Here, we evaluated the effects of cariprazine on body weight and blood pressure for bipolar I disorder (BP-I), schizophrenia, or as adjunctive treatment for major depressive disorder (MDD) using real-world data.

This special section underscores the importance of psychologists in improving and enhancing care for individuals with serious mental illnesses (SMIs). People with diagnoses typically included in the category of SMIs-schizophrenia, schizoaffective disorder, bipolar disorder, and other diagnoses with symptoms severely impacting functioning-typically have layered marginalities and experience significant social stigma in addition to mental health symptoms. The complexity of challenges commonly experienced by individuals with SMI requires that treatment providers have specialized knowledge, training, and skills to provide specialty care needed to support mental health recovery.
