My bipolar symptoms persist. Are light therapy and TMS safe?

Question

Hello doctor,

I have been managing bipolar disorder for several years and am currently in a depressive phase that has lasted almost three months. My psychiatrist has adjusted my mood stabilizer dosage, but I am still struggling with low energy, loss of interest, and trouble concentrating.

I have heard there are new medications specifically approved for bipolar depression that might work differently from traditional antidepressants, which can sometimes trigger mania.

Could you explain how these newer treatments work and whether they are safe alongside mood stabilizers? Also, is there any role for non-medication therapies like light therapy or TMS in improving bipolar depression symptoms over the long term?

Kindly suggest.

Hello,

Welcome to icliniq.com.

I understand your concern.

For bipolar depression, there are now medications approved specifically for this phase, such as Lurasidone, Quetiapine, and Cariprazine. These work differently from traditional antidepressants. They have mood-stabilizing and antipsychotic properties, which help treat depression without the same risk of switching into mania.

They can be used on their own or alongside your current mood stabilizer, with your psychiatrist monitoring for side effects and interactions.

Let me share with you other options your doctor might consider, including Lamotrigine (particularly for preventing future depressive episodes) or carefully supervised combinations of mood stabilizers and certain antidepressants in select cases.

Non-medication therapies can also play a role. These include:

Light therapy, when used cautiously and under supervision, can help some people with seasonal or morning-related worsening of symptoms.
Transcranial magnetic stimulation (TMS) is another option; research shows it may improve depressive symptoms in bipolar disorder, especially when medication alone has not been enough, though it is more often used in unipolar depression.

Alongside treatment, keeping a regular daily routine, tracking mood patterns, and using structured psychotherapy (such as interpersonal and social rhythm therapy) can help maintain stability over the long term.

I hope this helps. Please follow up if you have any questions or concerns.
