Objective: This case report highlights the clinical dilemmas encountered in deciding the diagnostic status of persons with unipolar depression who develop hypomania during antidepressant/electroconvulsive therapy.
Methods: We report a case of a 52 year-old Chinese lady, diagnosed with unipolar depression, which developed hypomania after she was started on T. Fluvoxamine 100mg daily and completed 8 sessions of Electroconvulsive therapy.
Results: Her diagnosis was revised to Bipolar Disorder and she was treated with T. Sodium Valproate 400mg twice daily after which she improved.
Conclusion: Treatment-emergent hypomania is likely a subtype of bipolar spectrum disorder and patients with Treatment - emergent Hypomania should be treated as Bipolar Disorder.
