What Causes Mood Disorders in Young People?

As we grow older, many of us have the tendency to idealize our child- and young-adulthood as a carefree, exploratory time, with few responsibilities or consequences.

Whether that view of our youth is true or not, North American statistics are showing a new trend towards the opposite: a study released by Statistics Canada on January 17 showed that over 11% of Canadians age 15-24 have experienced an MDE (major depressive episode) at some point in their lives. They are the demographic with the highest incidence of mental health disorders in North America.

The number appears to rising, as well: a study done in the US showed a 37% increase in mental health issues in young people between 2005 and 2014. Scarier still? Suicide is the second cause of death for kids in this age bracket.

So what’s causing poor mental health in our young adults? And, more importantly, what can we do to help?

The diet


The inflammatory response in the body and brain is largely due to the dysregulation of stress hormones, infections, environmental toxins and a diet rich in trans fats and sugar.

Canadian researchers found that a protein known to be a marker of inflammation was up to 1/3 higher in the brains of depressed patients compared to healthy ones.  Those with the most severe forms of depression also had the most inflammation.


The current SAD (standard American diet) is FULL of hidden sugars, allergens, and food stripped of its nutrients due to over-farming… all things that cause massive amounts of inflammation in the body!

Parents have less control over what their kids eat between the ages of 15-24, so there’s a good chance inflammatory foods are being consumed on a regular basis by this at-risk age group - much to their mental health’s detriment.

Healthy gut, healthy brain


On the subject of what we’re eating, our gut, or gastrointestinal (GI) system, is intimately connected to our brain. Just as emotional situations can cause feelings in our stomach (think about feeling butterflies, or feeling nauseous when we’re nervous), what’s going on in the gut can cause an emotional response.

In fact, did you know that 85% of our “happy hormones”, like serotonin and dopamine, are produced in our gut? Also, 80% of the immune system’s tissues are located in our gut.

The gut is as much of an epicentre in the body as the brain!

This is why it’s vitally important that we sustain a healthy gut flora. When we eat too many sugars, or allergens like wheat, dairy, corn and/or soy, our gut loses its ability to perform optimally.

Never mind just feeling sluggish or low-energy because we’re not digesting our food properly - if our GI system isn’t healthy, it won’t produce enough of the hormones we need to moderate our mood, either.

Screens & Social Media

If you’ve read my blog or visited me at my clinic, you’ll know that I advocate screen-free time strongly, particularly when mental health issues are involved.

Even for adults, who have (mostly) fully-formed opinions of themselves and the world, being exposed to a constant influx of information can have negative impacts on health, and self-worth.

For teens and young adults, too much screen time and exposure to social media can be like poison. As the brain develops it requires real-life social interaction and engagement, not 2D moderated interaction. Additionally, happiness studies have shown that a sense of community is crucial to living a happy, fulfilling life.

The isolation of staring at a screen all day, combined with the social pressure and downright bullying that happens on various social media platforms, make technology a bit of a lethal combo for a young person with a mood disorder - or on the verge of developing one.

How to help

If you suspect your child is struggling with their mental health, I highly recommend visiting a professional - be it an MD, and ND, or a counsellor - who can make suggestions for your unique situation.

That being said, there are some supplements & lifestyle changes you can implement right now.

Certain vitamin and mineral deficiencies and underlying hormone imbalances can lead to changes in our brain chemicals and lead to mood disorders.  The following are important to have checked by your MD or ND:  Vitamin D, Vitamin B12, iron, thyroid, adrenals, and blood sugars.



5-HTP may help to increase serotonin synthesis as depression and anxiety have been linked to serotonin imbalances in the brain.

Passionflower is known as a “calming” herb for anxiety or nervousness, insomnia, generalized anxiety disorder, and ADHD.

PharmaGABA is the most inhibitory neurotransmitter in the brain.  Low levels of GABA have been linked to anxiety, depression, and insomnia.

Probiotics will restore imbalances in the microbiota in the gut that can negatively affect brain function.

B vitamins, especially B12, B6, B5 and folic acid are often low in people with anxiety and depression.

Omega-3 fatty acids decrease the inflammatory response in the body, which seems to be an underlying cause in depression and anxiety.



Encourage your kids to get outside, see their friends in person, engage with their family, read, write (on paper!), play sports - anything that breaks up the lonely monotony that comes with “smart” technology. “Phone free” zones and times of day can be really effective, as can strict boundaries - your kids may not like the feeling of being without their technology at first, but the benefits far outweigh the bad moods!

More than anything, if you suspect your teen/young adult is suffering, a little love & compassion can go a long way. It’s hard enough to be a teenager, but nowadays kids and young adults are contending with a world  - and a level of mental health - we’ve never seen before. Try to be patient with them, and give them the support they need.
