[Approach to bipolar spectrum and subthreshold mood disorders]

Area of Science:

• Psychiatry and Mental Health
• Neuroscience
• Clinical Psychology

Context:

• Bipolar disorder diagnostic criteria have undergone significant revisions.
• Classifying mood disorders is challenging due to difficulties in defining boundaries.
• Current diagnostic approaches inadequately consider natural course, longitudinal, and family data.

Purpose:

• To highlight the limitations of current nosographic approaches for mood disorders.
• To discuss the need for revised classification models.
• To address the persistent gap in mood disorder classification.

Summary:

• The concept of bipolar disorder has evolved, but diagnostic complexity persists.
• Existing nosographic systems fail to incorporate crucial longitudinal and familial patient characteristics.
• Alternative models have been proposed, yet a classification gap remains, impacting research.

Impact:

• Improved diagnostic accuracy for mood disorders.
• Enhanced understanding of bipolar disorder's natural progression.
• Facilitation of more comprehensive clinical and neurobiological research into mood disorders.
