What treatment-resistant depression means

Treatment-resistant depression describes depression that has not improved after adequate trials of standard antidepressants. This is more common than many people realize, and it does not mean recovery is out of reach — it means it is time for a closer look and a new plan.

How psychiatric care helps

A psychiatric evaluation reviews your history, past treatments, and current symptoms to understand why earlier care fell short. From there, medication management and additional evidence-based options can be tailored to you, and we coordinate therapy referrals so support is well-rounded.
