Abstract
Abstract Background Bipolar disorder is one of the most severe and prevalent psychiatric conditions and a leading cause of disability worldwide. It has a profound impact on individuals’ lives and is associated with a markedly elevated risk of suicide and major functional difficulties. Over time, the understanding of bipolar disorder has expanded toward a broader bipolar spectrum, including both classical and attenuated (“soft spectrum”) forms, which continue to pose major therapeutic challenges. Objective This article offers a critical and conceptually informed analysis of the historical and contemporary evolution of psychotherapies for bipolar disorder. It examines their scope, strengths, and limitations in light of clinical heterogeneity and highlights the need to adapt psychotherapeutic strategies for attenuated or subthreshold bipolar spectrum presentations. Approach This article presents a conceptual and historically informed synthesis of major psychotherapeutic approaches, ranging from early psychoanalytic models to contemporary evidence-based interventions, with emphasis on their clinical principles and applicability across the bipolar spectrum. Discussion and conclusion Pharmacological advances have strongly influenced the development of psychotherapeutic interventions, contributing to a shift from predominantly psychoanalytic frameworks to modern, integrative approaches. Nevertheless, important clinical gaps remain, particularly for individuals within the soft bipolar spectrum who are frequently underdiagnosed and insufficiently treated. This article introduces an integrative-personalized psychotherapeutic framework intended to guide flexible, patient-centered clinical decision-making rather than impose a standardized protocol. It outlines the clinical principles, potential value, and implementation conditions of this model. This conceptual synthesis aims to enrich clinical reflection and encourage future research on personalized psychotherapy for bipolar spectrum conditions.
