Article Synopsis
  • Bipolar disorder (BD) is a complex mental health condition, and researchers aimed to identify a neurodevelopmental phenotype (NDP) that contributes to its development and impacts clinical outcomes.
  • By analyzing data from over 4,400 BD patients, they established nine specific clinical features that characterize this NDP, which are linked to poorer prognosis and treatment responses.
  • The findings suggest that patients with a higher NDP load may have overlapping genetic factors with ADHD, indicating a potential shared biological basis for these disorders.

Background: Nutrition is largely affected in bipolar disorder (BD), however, there is a lack of understanding on the relationship between dietary categories, BD, and the prevalence of metabolic syndrome. The objective of this study is to examine dietary trends in BD and it is hypothesized that diets with increased consumption of seafood and high-fiber carbohydrates will be correlated to improved patient outcomes, and a lower frequency of metabolic syndrome.

Methods: This retrospective cohort study includes two French cohorts.

Article Synopsis
  • Individuals with bipolar disorders (BD) tend to have a shorter life expectancy, prompting the need for easily measurable markers of accelerated aging like BioAge, calculated from routine blood tests and physical exams.
  • In a study of 2,220 outpatients with BD, results showed that a small percentage had significant BioAge Acceleration, which is linked to factors such as young age, male sex, being overweight, and sleep issues.
  • Further research is needed to confirm these findings with different groups and explore whether improving factors like metabolic health and sleep could impact aging rates in individuals with BD.

Article Synopsis
  • This study investigates the link between mitochondrial blood biomarkers, specifically lactate and circulating cell-free mitochondrial DNA, and markers of metabolic syndrome in bipolar disorder patients, hypothesizing that lactate levels would be higher in those with metabolic syndrome.
  • The research involved a large cohort of 837 stable bipolar disorder patients and 237 others for validation, revealing that higher lactate levels correlated significantly with factors like triglycerides and blood pressure, indicating a strong association with metabolic syndrome.
  • The findings suggest that while lactate is a key biomarker related to metabolic syndrome in bipolar patients, circulating mitochondrial DNA levels do not show this same correlation, highlighting the potential for personalized treatment strategies based on these metabolite profiles.

Objectives: Electroconvulsive therapy (ECT) is one of the most effective treatments in mood disorders, mainly in major depressive episode (MDE) in the context of either unipolar (MDD) or bipolar disorder (BD). However, ECT remains a neglected and underused treatment. Older people are at high risk patients for the development of adverse drug reactions.

Background: The care environment significantly influences the experiences of patients with severe mental illness and the quality of their care. While a welcoming and stimulating environment enhances patient satisfaction and health outcomes, psychiatric facilities often prioritize staff workflow over patient needs. Addressing these challenges is crucial to improving patient experiences and outcomes in mental health care.

Background: Effective interventions need to be implemented successfully to achieve impact. Two theory-based measures exist for measuring the effectiveness of implementation strategies and monitor implementation progress. The Normalization MeAsure Development questionnaire (NoMAD) explores the four core concepts (Coherence, Cognitive Participation, Collective Action, Reflexive Monitoring) of the Normalization Process Theory.

Article Synopsis
  • Bipolar disorder is linked to premature cellular aging, evidenced by shortened telomere length (TL), particularly in a subgroup of young individuals.
  • A study analyzed 542 individuals with bipolar disorder, finding a cluster of young people (average age 29.64) with significantly shorter TL.
  • Gene expression analysis revealed decreased levels of the gene POT1 in this subgroup, indicating a potential new mechanism related to telomere shortening in bipolar disorder.

Introduction: The purpose of this update is to add newly approved nomenclatures and treatments as well as treatments yet to be approved in major depressive disorder, thus expanding the discussions on the integration of resistance factors into the clinical approach.

Methods: Unlike the first consensus guidelines based on the RAND/UCLA Appropriateness Method, the French Association for Biological Psychiatry and Neuropsychopharmacology (AFPBN) developed an update of these guidelines for the management of partially responsive depression (PRD) and treatment-resistant depression (TRD). The expert guidelines combine scientific evidence and expert clinicians' opinions to produce recommendations for PRD and TRD.

Functional neurological disorder (FND) is a common cause of persistent and disabling neurological symptoms. Diagnostic delay may lead to no treatment, inappropriate treatment or even iatrogenic symptoms. Yet, several treatments significantly reduce physical symptoms and improve functioning in FND patients even though not all patients respond to the currently available treatments.
