An Integrative Medicine Approach to Childhood Depression

Medically reviewed by 
An Integrative Medicine Approach to Childhood Depression

The escalating prevalence of childhood depression raises a growing concern, emphasizing the imperative for nuanced and practical approaches to address this complex issue. Current statistics underscore an alarming increase in depression rates among children, estimating that 2.4 million children were diagnosed with depression in 2020. After the beginning of the COVID-19 pandemic, 5 million kids experienced behavior and conduct problems, a 21% increase from the previous year. Unfortunately, 20% of children requiring mental health services do not receive the care they need. This article delves into the realm of integrative medicine for childhood depression, introducing a holistic approach that recognizes the interconnectedness of physical, emotional, and environmental factors influencing a child's mental health. (23


What is Childhood Depression?

Childhood depression is a complex and often misunderstood mental health condition that affects a significant number of children worldwide. Unlike adults, children may not always possess the verbal skills to express their emotions, making it challenging for parents and caregivers to identify the signs of depression.

Childhood major depressive disorder (MDD) involves persistent feelings of sadness, hopelessness, and a lack of interest in activities that once brought joy. It goes beyond the normal ups and downs that children experience as a part of growing up. It can manifest in various ways, such as changes in behavior, academic performance, and social interactions. Understanding the distinct nature of childhood depression is paramount for early detection and intervention. Recognizing the signs and symptoms is crucial for parents, educators, and healthcare professionals. Examples of behaviors and symptoms often seen in children with depression include:

  • Feeling sad, hopeless, irritable, worthless, useless, or guilty
  • Losing interest and enjoyment in fun activities 
  • Decline in academic performance
  • Changes in eating patterns
  • Changes in energy patterns
  • Difficulty paying attention
  • Showing signs of self-injury and self-destructive behavior
  • Frequent stomachaches and headaches without apparent medical cause (2, 11

Left untreated, childhood depression can lead to severe consequences that extend into adulthood. A decades-long study published in 2021, including over 1,400 participants, found that childhood/adolescent depression was associated with poorer health outcomes in adulthood. Increased risk of anxiety, substance abuse, poor health and social functioning, and criminal activity were found to be associated with childhood depression. (9)  

Additionally, severe, untreated depression can lead to suicidal thinking and attempts. Suicide is among the leading causes of death for youth ages 10-24 years. (2

The Role of Functional Medicine Lab Testing

Unlike conventional approaches, functional medicine seeks to uncover underlying imbalances that may contribute to depressive symptoms. With targeted lab tests, integrative medicine practitioners aim to identify factors such as nutrient deficiencies, hormonal imbalances, and gut health issues that may influence a child's mental well-being.

Functional medicine employs a range of lab tests designed to delve deeper into the root causes of childhood depression. Lab tests commonly ordered in the integrative pediatric care setting include panels to assess nutrient levels such as vitamins and minerals (like the Whole Blood Nutrient Profile by Vibrant Wellness), panels to address stress hormones (like the Sleep and Stress Panel by Ayumetrix), and panel to evaluate the health of the gut microbiome (like the GI360 Microbiome test by Doctor's Data). Testing Vitamin D levels are also important since lower serum levels have been associated with depression. By examining these aspects of health, practitioners can gain insights into the intricate web of factors influencing a child's mental health, moving beyond the traditional symptom-focused approach.

The information gathered from functional medicine lab tests becomes instrumental in developing personalized treatment plans tailored to the unique needs of each child. For instance, identifying nutrient deficiencies allows for targeted supplementation to address specific imbalances. Hormonal imbalances can be addressed through lifestyle modifications and nutritional interventions. Assessing gut health enables practitioners to implement dietary changes or probiotic supplementation to promote a healthy gut microbiome.


Conventional Treatments for Childhood Depression

Traditional treatments for childhood depression often include a combination of traditional therapeutic approaches, each designed to alleviate symptoms and support the child's mental health. For mild to moderate depression, cognitive behavioral therapy (CBT), or talk therapy, is the first-line treatment of choice. This approach involves a trained mental health professional working with the child to explore and understand their emotions, thoughts, and behaviors. By providing a safe and supportive environment, psychotherapy aims to help children develop coping mechanisms and strategies to navigate the challenges associated with depression. (3

For younger children, parent-child interaction therapy (PCIT) is a type of treatment where parents are taught techniques to successfully interact with their kids in controlled situations under the guidance of a clinician. Clinical trials have shown that PCIT is an effective therapeutic modality associated with favorable clinical outcomes, including lower depression severity scores, improved functioning, and greater emotional regulation skills. (31

For moderate to severe depression, antidepressant medications, typically belonging to the class of selective serotonin reuptake inhibitors (SSRIs), are recommended in addition to CBT. Fluoxetine and escitalopram are FDA-approved for treating depression in children and teens. It should be noted that SSRIs and other antidepressants have a black box warning for increased risk of suicidal ideation and behavior with use; close monitoring during therapy and dose titration helps reduce this risk. (3

The Role of Diet and Nutrition in Childhood Depression

In recent years, there has been a growing recognition of the intricate connection between diet, nutrition, and mental health, even in the realm of childhood depression. The food children consume plays a vital role in supporting their overall well-being, influencing both physical and mental aspects of health. Research suggests that certain dietary patterns can profoundly impact mood regulation and cognitive function. Teens consuming a nutrient-poor, Western diet face an 80% higher risk of depression compared to their counterparts who follow a high-quality, whole-foods diet. (26

A healthy diet positively influences brain health by promoting brain development, neurotransmitter synthesis, and a healthy gut microbiome. Additionally, a healthy, anti-inflammatory diet decreases neuroinflammation, known to be a major contributor to depression. Conversely, poor nutritional habits and nutritional deficiencies are associated with increased rates of depression in teens and poorer mental health outcomes (17, 25). (26

The link between diet and mental health stems from the brain's reliance on various nutrients to function optimally. Nutrients important in brain and mental health include zinc, omega-3 fatty acids, vitamin B12, vitamin C, and iron. A deficiency in any of these nutrients, and others, may contribute to an imbalance that could manifest as depressive symptoms in children. (6

Moreover, the gut-brain connection has emerged as a significant factor in mental health. Dietary patterns directly impact the composition and diversity of the gut microbiome. Diets high in fat and sugar reduce populations of healthy bacteria in the gut, contributing to intestinal dysbiosis (26). Patients with MDD have been found to have distinct dysbiotic intestinal patterns compared to healthy controls. The good news is that a balanced and diverse diet promotes a healthy gut microbiome, positively influencing mood and emotional well-being. Fermented foods, high-fiber foods, and probiotics contribute to a flourishing gut environment. (10, 21

Herbal and Nutritional Supplements for Childhood Depression

In the quest to explore alternative and complementary approaches to managing childhood depression, herbal remedies and nutritional supplements have garnered attention for their potential benefits for childhood depression and mental health. 

Omega-3 fatty acids, found abundantly in fatty fish like salmon and certain plant sources like flaxseeds, have positively affected mood regulation and cognitive function. These essential fatty acids are crucial for the development and function of the brain, and incorporating them into a child's diet may contribute to overall mental well-being. In one clinical trial investigating the effects of omega-3 fatty acids on depressive symptoms in children, researchers found that omega-3 supplementation modulates depressive symptoms. Children who received omega-3 supplementation exhibited improvements in depressive symptoms, and there were corresponding changes in serum levels of omega-3 fatty acids. 

St. John's Wort, an herbal supplement derived from the Hypericum perforatum plant, has a long history of use in traditional medicine for mood-related disorders. Most studies on this herb have been conducted in adults; however, one study investigated its use in 101 children under 12. Children were treated with St. John's wort dosed between 300-1800 mg daily for 4-6 weeks. The results of the study indicate that St. John's wort is a safe and effective natural intervention for mild to moderate symptoms of childhood depression. Children taking St. John's wort should be monitored closely for common side effects, including stomach upset, skin rashes, and sensitivity to sunlight. 

Serum vitamin D levels are inversely correlated to clinical depression. The results from a cross-sectional study including 451 adolescents aged 11-18 years showed that participants with lower vitamin D levels were more likely to experience symptoms of depression. This suggests that ensuring adequate vitamin D intake may have a role in preventing and treating depression.

Mind-Body Therapies for Childhood Depression

In recent years, a paradigm shift in the approach to mental health has led to increased exploration of mind-body therapies as complementary interventions for childhood depression. Data from the 2012 National Health Interview Survey show that 3.7% of American children ages 4-17 years use mind-body approaches, including yoga, meditation, mindfulness-based stress reduction, hypnotherapy, guided imagery, and biofeedback. (1

These mind-body therapies operate on the principle that the mind and body are interconnected, and addressing one can positively influence the other. Focusing on physical postures, breath control, and meditation, yoga provides children with tools to enhance self-awareness and emotional regulation. Similarly, meditation and mindfulness techniques encourage the cultivation of a present-focused awareness, fostering resilience against negative thought patterns associated with depression. (24

Research findings support the effectiveness of mind-body therapies in managing childhood depression. For example, one study found that game-based biofeedback (utilizing interactive games with biofeedback mechanisms) was associated with reduced anxiety and depression in children. A large pool of evidence also supports the use of yoga, meditation, and deep breathing in treating depression in patients of varying ages.

Integrating Lifestyle Changes for Childhood Depression

Lifestyle factors play a pivotal role in promoting overall well-being. Addressing elements such as sleep, physical activity, and social interactions can significantly impact a child's mental health and contribute to a comprehensive strategy for managing depressive symptoms.

Adequate and quality sleep is foundational to mental health, especially in children. In a comprehensive examination between sleep patterns and mental health in children, which employed various methods to assess this relationship, researchers found a significant association between sleep quality and mental health outcomes in the general pediatric population. ​​Sleep deficiency changes activity in parts of the brain, making it difficult to make decisions, solve problems, control emotions and behavior, and cope with change. Sleep deficiency has been linked to depression and suicide. Establishing a consistent sleep routine, maintaining a comfortable sleep environment, and limiting screen time before bedtime are practical strategies to promote healthy sleep habits. Ensuring that children get the recommended amount of sleep for their age group contributes to improved mood regulation and resilience. (14

Exercise increases neurotrophic factors, neurotransmitters, and hormones associated with optimal brain health and mood. One study found that partaking in 40-50 minutes of exercise three times weekly for 12 weeks significantly improves depressive symptoms in children and adolescents. However, research also consistently shows that some physical activity is better than none. Encouraging children to engage in age-appropriate physical activities, whether it's playing a sport, going for a bike ride, or participating in a dance class, can contribute to improved mood and overall well-being.

Social connections are crucial for mental health, and fostering positive relationships can be a powerful tool in managing childhood depression. Encouraging social interactions with peers, family members, and friends helps combat isolation and foster feelings of belonging. (28

Family and Community Support

Treating childhood depression extends beyond clinical interventions, emphasizing the critical role of family and community support in a child's path to mental well-being. The immediate social environment, characterized by family dynamics and community interactions, significantly shapes a child's emotional resilience in facing the challenges of depression.

Family support stands as a cornerstone in addressing childhood depression, providing a nurturing space for children to express their emotions and seek help. Parents and caregivers play a pivotal role in recognizing depressive signs, offering unconditional love, and fostering open communication within the family. Strategies for creating a supportive family environment involve encouraging open dialogues, normalizing discussions about mental health, establishing consistent routines, and educating family members about childhood depression to promote empathy and understanding.

In addition to family support, the broader community plays a crucial role in a child's mental health. Schools, local organizations, and community resources contribute to a supportive network that reinforces emotional well-being. Collaborating with school staff, engaging in community programs focused on mental health awareness, and facilitating peer support networks are strategies to foster community support. These initiatives aim to reduce stigma, promote empathy, and provide resources and a sense of belonging for children and their families.


Key Takeaways: Using Integrative Medicine for Childhood Depression

Embracing integrative care for childhood depression is crucial for cultivating a holistic and individualized approach to treatment. Recognizing that a child's well-being goes beyond conventional interventions, an integrative strategy considers various factors influencing mental health. By addressing physical, emotional, and environmental aspects, an integrative approach provides a comprehensive framework tailored to the unique needs of each child. This method encourages collaboration between healthcare professionals, families, and communities to create personalized treatment plans that prioritize the entirety of the child's well-being.
