Bipolar Disorder Explained: Symptoms-Causes-Types & Effective Treatments
In Episode 2.7 of Psychiatry Boot Camp, we shine a spotlight on bipolar disorders—complex mood conditions often misunderstood by both patients and providers.
Joining us is world-renowned expert Dr. Roger McIntyre, Professor of Psychiatry and Pharmacology at the University of Toronto and Head of the Mood Disorders Psychopharmacology Unit at the University Health Network in Toronto, Canada. Dr. McIntyre is one of the most cited researchers in mood disorders and brings deep insight into both clinical practice and emerging science.
🧠 In This Episode, You’ll Learn:
✔️ The core clinical features of Bipolar I and Bipolar II disorders
✔️ Diagnostic challenges and early warning signs in clinical settings
✔️ The neurobiology and pathogenesis behind mood instability
✔️ How circadian rhythm disruption contributes to symptom onset and relapse
✔️ Differences in mania vs. hypomania, and how they shape subtype diagnosis
✔️ Evidence-based first-line treatments, including medications and lifestyle interventions
✔️ The role of trauma and life adversity in bipolar spectrum presentations
✔️ A practical approach to long-term management and psychoeducation
📌 Why This Episode Matters:
Bipolar disorder affects millions worldwide and is often:
Misdiagnosed as unipolar depression
Mistaken for personality or anxiety disorders
Overlooked in patients with trauma histories
Treated ineffectively due to lack of accurate subtyping
Dr. McIntyre helps us break through the diagnostic fog by blending cutting-edge pathophysiology with practical tools clinicians can apply immediately.
🌙 Bipolar Disorder & Circadian Rhythms:
A highlight of the discussion is how disrupted sleep-wake cycles can trigger or worsen manic and depressive episodes. You’ll gain a better understanding of:
The bi-directional relationship between sleep and mood
Strategies for rhythm stabilization as part of the treatment plan
How circadian science is influencing future pharmacologic research
