Dear Colleagues,

Bipolar disorder remains a complex and heterogeneous psychiatric condition associated with significant morbidity, functional impairment, and elevated risk of relapse and suicide. Despite advances in psychopharmacology and psychosocial interventions, numerous challenges persist in its diagnosis and management, including delayed recognition, treatment resistance, suboptimal adherence, and the burden of comorbidities.

This Special Issue, “Bipolar Disorder: Treatment Challenges and Innovative Therapeutic Strategies,” aims to provide a comprehensive and up-to-date overview of emerging concepts and new studies in the treatment of bipolar disorder, addressing both established and novel pharmacological strategies, including mood stabilizers, second-generation antipsychotics, antidepressants and rapidly developing approaches such as glutamatergic agents, drugs with other alternative mechanisms of action , and other forms of pharmacological or non-pharmacological treatment. Special emphasis will be placed on difficult-to-treat populations, including patients with treatment-resistant bipolar depression, rapid cycling bipolar disorder, and those burdened with concurrent psychiatric or somatic conditions. In addition, the issue aims to explore the role of biomarkers, digital tools, and personalized medicine in improving diagnostic accuracy and optimizing therapeutic outcomes.
