What treatments work fastest for bipolar depression?

Question

Hello doctor,

My 29-year-old daughter has bipolar disorder type 2 and is currently in a depressive episode that has lasted for four months. She is taking Lamotrigine 200 mg daily and Quetiapine 300 mg at night, but she is still severely depressed. She cannot get out of bed most days, does not shower, and is not eating properly. She lost her job two months ago because she missed too much work.

Her psychiatrist added Bupropion, but it triggered a hypomanic episode, so she had to stop it. Increasing the Quetiapine made her sleep up to 16 hours a day. Her bipolar depression is so much worse than her manic episodes, which are usually mild. She has a 5-year-old son whom I am taking care of because she cannot function as a mother right now.

Her thyroid function was checked, and her TSH is normal. She is not using drugs or alcohol. She was doing well for two years before this depressive episode began. She has also gained 40 pounds from the medications, which makes her even more depressed.

She has been talking about not wanting to live anymore, which really scares me. Is there any treatment for bipolar depression that works faster? Electroconvulsive therapy (ECT) was mentioned, but she is scared of it. We really need help for her soon.

Please help.

Thank you.

Hello,

Welcome back to icliniq.com.

I understand your concern.

Bipolar depression causes more dysfunction in life compared to mania and is therefore more resistant to treatment. There are a few options that I would like to discuss, and you can choose according to your needs and what is available.

One of the better options is to add cognitive behavioral therapy (CBT). It is not only effective but also risk-free, with no side effects. The therapist will work on her dysfunctional thoughts and help her adopt more helpful behaviors. They will also identify the factors that maintain her depression. It usually takes about four to six sessions to achieve noticeable effects, which can be long-lasting.

Another option is to switch Quetiapine to the Olanzapine or Fluoxetine combination (6/25 mg in the morning and at night). This is considered one of the most effective first-line treatments. Weight gain can occur, but it can be managed through lifestyle measures such as dietary modifications, regular exercise, or medications if needed.

A further option is to switch from quetiapine to lithium. Lithium not only helps manage depressive symptoms but also prevents relapse and reduces suicidal behavior by up to 80 percent. It is important to monitor blood levels regularly while using lithium.

Other options include Ketamine injections and electroconvulsive therapy (ECT). Both are rapid-acting and highly effective treatments. Although there are many myths about them, managing the patient’s suicidal thoughts is a priority, so these options should be seriously considered. Both are very safe when administered properly.

It is important to understand that the risk of suicide in her case is significant, and therefore, more aggressive treatment options should be preferred. If I had to make a decision, I would add ketamine or ECT, switch quetiapine to lithium, and later introduce CBT to manage both depressive symptoms and suicide risk.

Finally, it is crucial to recognize that stressors and maintaining factors play a key role in sustaining the disorder, even when the best combination of medications is used. These factors, such as conflicts, job stress, or other life pressures, should be identified and managed as part of her overall treatment plan.

The probable causes are social or psychological stress, or resistant bipolar depression, and the investigations to be done are a lipid profile and HBA1C.
Probable diagnosis is bipolar type II disorder, and the treatment plan is to use Quetiapine with Olanzapine or Fluoxetine combination, or add CBT(complete blood test), or switch Quetiapine with Lithium, or add ECT (electroconvulsive therapy), or Ketamine for rapid and suicidal acts.
If you have a query, please arrange a follow-up meeting. Avoid caffeine or other substance abuse to prevent depression.

I hope this helps.

Kindly follow up if you have more concerns.

Thank you.
