Why do I have bipolar depression despite taking medications?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I was told I have bipolar depression, and I do not respond well to selective serotonin reuptake inhibitors or mood stabilizers. I often crash into depression even after small stress. My psychiatrist mentioned Ketamine or maybe transcranial stimulation, but I am not sure if those are safe.

Is there a newer approach for treatment-resistant bipolar depression that is not too sedating?

I also had weight gain on medications, and I am now prediabetic.

Kindly help.

Hello,

Welcome to icliniq.com.

I understand your concern.

Bipolar depression can indeed be very challenging to manage, especially when traditional treatments like selective serotonin reuptake inhibitors or mood stabilizers are not effective or cause intolerable side effects. The good news is that newer and evidence-based options are available for treatment-resistant bipolar depression, and many are less sedating and more metabolically friendly:

  1. Ketamine or Esketamine is a fast-acting antidepressant used in controlled clinical settings. Esketamine (a nasal spray version) is Food and Drug Administration-approved for treatment-resistant depression. While Ketamine is not a first-line therapy, it can offer rapid relief of severe depressive symptoms, particularly in those who have not responded to multiple other medications. They are generally well-tolerated under supervision, though they are not suitable for all patients, especially those with active psychosis or a substance use history.

  2. Transcranial magnetic stimulation is a non-invasive brain stimulation technique approved for major depression and showing promise in bipolar depression, particularly for those who do not respond to medications. It is done in outpatient sessions and does not involve anesthesia or sedation. It is generally well-tolerated with minimal side effects like scalp discomfort or headache.

  3. Lurasidone and Cariprazine are newer-generation atypical antipsychotics approved specifically for bipolar depression. They tend to be less sedating and have lower metabolic risks, which might be beneficial given your concerns about prediabetes.

  4. Cognitive behavioral therapy, interpersonal and social rhythm therapy, and bipolar-specific therapies can help manage mood swings and reduce relapse, especially when stress is a major trigger.

  5. Lifestyle and integrative options are interventions like regular sleep-wake routines, anti-inflammatory diets (like the Mediterranean diet), omega-3 supplementation, and mindfulness that have supporting evidence and might help stabilize mood alongside medical treatment.

Given your history of sensitivity to medications and metabolic side effects, it is crucial to tailor your treatment plan carefully with your psychiatrist. Exploring Ketamine or transcranial magnetic stimulation could be a safe and effective next step under professional guidance.
