Root-Cause Treatment for Depression

José is on his third antidepressant, with no relief. He asks you what else he can try. How do you work with patients like José?

Variable reports on the efficacy of antidepressants compared to placebo,1,2 combined with the high prevalence of depression,3,4 has left many clinicians challenged about how to help patients with depression. According to one report, 42% of doctors had a hard time differentiating between unhappiness and clinical depression.5 What’s more, clinicians differ greatly in how they diagnose depression—from using checklists to using “gut sense.”6 Perhaps due to lack of time or the inherent difficulties of diagnosing it, some clinicians are not inquiring much or at all about depression.7

When several prescriptions fail, the clinical encounter can seem as hopeless as the patient feels. Depression is a multi-factorial condition with a large number of potential antecedents and triggers. Given the wide range of potential causes and factors that influence depression, how can you get to the root cause for an individual patient? At IFM’s Energy Advanced Practice Module (APM), one lecture delves into the considerations and labs you can use to pinpoint the causes of depression for each individual and treat it at its roots.

For patients like José, who have tried several antidepressants to no avail, other methods may yield better results. Testing his fatty acids may indicate that he is deficient and would respond well to EPA treatment (like many others8-10). If José was a woman who experienced depression after giving birth, zinc could be playing a role in postnatal depression.11 Oral magnesium supplementation may be helpful, as those who ingest more magnesium have a lower incidence of depression.12,13 Exercise and movement are also not to be overlooked. Research shows that physical activity alone can treat mild to moderate depression symptoms.14-16

Functional Medicine emphasizes treating the root cause for each individual patient. Learn more about this approach in our free, interactive, online course, Introduction to Functional Medicine.
