BACKGROUND: Abnormalities in dopamine and norepinephrine signaling are implicated in cognitive impairments in bipolar disorder (BD) and attention-deficit hyperactivity disorder (ADHD). This systematic review by the ISBD Targeting Cognition Task Force therefore aimed to investigate the possible benefits on cognition and/or ADHD symptoms and safety of established and off-label ADHD therapies in BD. METHODS: We included studies of ADHD medications in BD patients, which involved cognitive and/or safety measures...

BACKGROUND: Ketamine is increasingly used for treatment-resistant depression (TRD) while its mechanism of action is still being investigated. In this systematic review, we appraise the current evidence of metabolomic biomarkers for racemic ketamine and esketamine in patients with TRD and healthy controls (HCs). METHODS: A comprehensive search of several databases (Ovid MEDLINE®, Embase, and Epub Ahead of Print) was performed from each database's inception to June 29, 2022, in any language, was conducted...

BACKGROUND: Bell's mania was first described in 1849, and other terms have been used to describe this condition, including delirious mania, mania with delirium, and excited delirium. However, no international diagnostic manual has included mania as an independent diagnostic tool. The criteria for delirious mania were proposed by Bond et al. METHODS: We present a case of a man without a personal or family psychiatric history who experienced his first manic episode of delirium and psychosis at 76 years old...

BACKGROUND: Bipolar depression is the major cause of morbidity in patients with bipolar disorder. It affects psychosocial functioning and markedly impairs occupational productivity. Anhedonia is one of the most debilitating symptoms of depression contributing to treatment resistance. It correlates with suicidality, low quality of life, social withdrawal, and poor treatment response. Currently, there is no approved treatment specifically targeting anhedonia. Emerging evidence suggests that ketamine possesses anti-anhedonic properties in individuals with depression...

The perinatal period is an extremely delicate phase that can involve a high risk for onset of depressive disorders. The Edinburgh Postnatal Depression Scale (EPDS) is a widely validated instrument for assessing perinatal depressive symptoms, including the dimension of anhedonia. There are studies suggesting that the neural mechanism underlying the occurrence of anhedonia in patients with major depressive disorder (MDD) and bipolar depression (BD) might be distinct. Anhedonia seems to represent a more stable and frequent symptom in women with postpartum bipolar relative to unipolar depressive disorder and is associated with significantly higher depressive symptom severity...

OBJECTIVE: Accurate information on the frequency and prevalence of manic or mixed episodes is important for therapeutic, prognostic, and safety concerns. We aimed to estimate the risk of relapse of manic and mixed episodes after delivery in women with bipolar I disorder or schizoaffective disorder-bipolar type. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a comprehensive literature search in PubMed, PsycINFO, Embase, and Cochrane databases was carried out on November 17, 2022, using the terms ((bipolar disorder) OR (manic depressive illness)) AND (mania)) AND (postpartum)) AND (recurrence)) AND (relapse)...

OBJECTIVE: Treatment of bipolar disorder (BD) involves complexities especially when patients come with significant sensitivity to various psychotropic medications and comorbidities. The following cases aim to recapitulate and discuss some of such situations. CASES: Case 1: A 36-year-old man with intellectual development disorder and BD experienced catatonia, seizures, and hyperammonemia following valproate administration. Treatment involved electroconvulsive therapy (ECT) and a tailored medication regimen, ultimately leading to stability...

To the Editor, we follow the topic "A chat about bipolar disorder1 ". According to the study's findings, ChatGPT proved its ability to deliver basic and informative information on bipolar disorders.

OBJECTIVE: Myelinolysis is a neurological condition that can display diverse psychiatric symptoms, with electrolyte imbalance, alcoholism and malnutrition being the frequent causes. Rapid correction of hyponatremia may trigger pontine and extra-pontine myelinolysis. CASES: This paper examines two cases: one of hyponatremia after antihypertensive use and the other of myelinolysis due to rapid correction of hyponatremia. Since myelinolysis appeared as a manic episode, the patients sought treatment at the psychiatry outpatient clinic...
