Dr. Jim Phelps discusses diagnosing bipolar disorder within a mood spectrum and the challenges of transitioning from a categorical to dimensional approach. The podcast explores treatment considerations, risks and benefits of prescribing an SRI, alternative mood stabilizers, and essential diagnostic tools such as the bipolarity index and mood check questionnaire.
Diagnosing bipolar disorder within a mood spectrum requires considering factors like family history, age of onset, course of illness, and response to treatment.
Patients with bipolar disorder often experience adverse reactions to antidepressants and struggle with treating depressive episodes using antidepressant monotherapy.

Shifting towards a dimensional approach
The Royal Australian and New Zealand College of Psychiatrists introduced their latest clinical guidelines for mood disorders, embracing a dimensional approach that moves away from the categorical diagnostic system of the DSM. This shift represents an evolution that has been in progress for many years, with the concept of a mood spectrum first formalized in 2002 by Gaimi and Goodwin. The transition presents a challenge when diagnosing bipolar disorder, as determining the appropriate treatment strategy for patients in the middle of the spectrum remains uncertain.
Assessing bipolarity in patients
To determine the level of bipolarity in a patient, various factors should be considered. These factors include family history of bipolar disorder, onset of symptoms typically between 18 to 24 years, the course of illness characterized by high recurrence and episodic mood episodes, and the response to treatment. Notably, patients with bipolar disorder often experience adverse reactions to antidepressants and have difficulty treating depressive episodes with antidepressant monotherapy. These non-manic markers carry 80% of the diagnostic weight in the bipolarity index, with the DSM manic symptoms accounting for only 20%. A comprehensive assessment can be conducted using the mood check questionnaire to gather essential diagnostic data.
In this podcast, Dr. Jim Phelps discusses the issue of diagnosing bipolar disorder within the framework of a mood spectrum. How bipolar should a patient be before switching treatment strategies? Listen in for tips and practical takeaways to answer this question and guide decision making.
