Lifestyle Alternatives to Antidepressants

White feather on a black stone: idea for a condolence card or balance concept.

Depression is a common psychiatric disease that particularly affects older adults, at 15-20% of the US population.1 Yet despite this, a groundbreaking study in 2018 found that only a small fraction of patients diagnosed with depression actually start treatment—approximately one-third.2

Only 1/3 of patients diagnosed with depression start treatment.

For those who do adhere to antidepressant therapies, treatment of the acute phase of major depressive disorder (MDD) led to a greater number of adverse events in patients 65 and over, according to a 2019 systematic review.1 Antidepressants included in the study were the following:

  • Selective serotonin reuptake inhibitors (SSRIs)
  • Serotonin norepinephrine reuptake inhibitors (SNRIs)
  • Bupropion
  • Mirtazapine
  • Trazodone
  • Vilazodone
  • Vortioxetine

Specifically, the reports found that SSRIs and SNRIs led to a greater number of study withdrawals due to adverse events, and duloxetine increased the risk of falls.1

Non-adherence to antidepressants is also common.3 A 2017 survey found that 68% of the females were non-adherent to their prescribed antidepressant therapy.3 Forgetfulness was the main reason for missing doses. Another study showed that antidepressant non-adherence is common among veterans, with ineffectiveness and side effects as commonly reported reasons.4

When several different prescriptions fail or the patient does not adhere to the prescribed treatment, 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. How can you get to the root cause for an individual patient? What are some alternatives to antidepressant medications?

The Path Forward: Alternatives to Antidepressants

The Functional Medicine model emphasizes a multi-pronged approach to health and wellness, engaging patients in a therapeutic partnership that recognizes that the current conventional paradigm does not optimally address the needs of patients with depressive symptoms. In the following video, IFM educator Patrick Hanaway, MD, talks about how a clinician might unravel the root cause of depression by looking at several factors, including vitamin D and other vitamins, amino acids, and minerals—as well as the gut microbiome.

IFM educator Patrick Hanaway, MD, is a board-certified family physician who works in clinical practice at Family to Family: Your Home for Whole Health Care in Asheville, NC. He has served on the executive committee for the American Board of Integrative Medicine, is past president of the American Board of Integrative Holistic Medicine, and is the former director of research at Cleveland Clinic Center for Functional Medicine.

Clearly, variable reports on the efficacy of antidepressants,5,6 combined with the high prevalence of depression,7,8 have left many clinicians challenged about how to help patients. According to one report, 42% of doctors had a hard time differentiating between unhappiness and clinical depression.9 What’s more, clinicians differ greatly in how they diagnose depression—from using checklists to using “gut sense.”10 Perhaps due to lack of time or the inherent difficulties of diagnosis, some clinicians are not inquiring much or at all about depression.11 But there is a wealth of medical research on the topic, and studies continue to point to the effectiveness of non-pharmacological treatments for depression.

For patients who have tried several different antidepressants to no avail, other methods like diet may yield better results.

Epidemiological studies suggest there is an association between diet and mental health.12 A 2019 study found that long-term adherence to a healthy diet may offer protection against recurrent depressive symptoms.13 Analyses were conducted on a sample of 4,949 men and women, and diet scores were calculated using data collected from food frequency questionnaires repeated over 11 years of exposure. Higher scores on the Alternative Healthy Eating Index-2010, Dietary Approaches to Stop Hypertension, and transformed Mediterranean diet were associated with a lower risk of recurrent depressive symptoms.13

Evidence suggests that dietary or supplemented intake of other nutrients, such as those listed below, can be protective or reduce depressive symptoms:

  • Vitamin K14
  • Fatty acids15,16,17
  • Zinc (postpartum depression)18
  • Magnesium19,20

Exercise and movement are also not to be overlooked. Research suggests that physical activity alone can treat mild to moderate depression symptoms.21,22,23 A 2015 cross-sectional national data study found that higher physical activity levels were associated with fewer self-reported days of poor mental health.24 Another large cohort study found that regular leisure-time exercise is associated with reduced incidence of future depression; it was predicted that 12% of future cases of depression could have been prevented if all participants had engaged in at least one hour of physical activity each week.25 Accumulating evidence also suggests that tai chi can significantly regulate emotion and relieve the symptoms of depressive disorders.26

Depression is a common and complex mood disorder that can severely affect a patient’s quality of life and even their family dynamic. Sources of distress can be biological, psychological, and/or social, and in the Functional Medicine model, it is incumbent upon the clinician to unravel the root cause of depression in order to address it effectively. Functional Medicine tools like the timeline, as well as other resources, can help the patient cope, manage, and support a path to recovery.
