Relax With CBD

Moments of sadness or feeling stuck are a part of life, but we can usually find the strength to process our feelings and recover.

But when sadness or stuckness grab hold of your life with no end in sight, this can morph into depression, a disorder that can harm both mind and body.

If you suffer from untreated depression, we urge you to seek professional support. However, recovering from depression is highly individual — and better results come with a combination of approaches, including holistic lifestyle changes and self-care programs.

 

Depression: Where Does It Come From?

Many people still believe that depression is caused by a chemical imbalance — a serotonin deficiency. But this is a myth perpetuated by pharmaceutical advertisements. Serotonin is definitely part of the big picture — but the verdict is still out about who could use more or less serotonin, and depression is linked to many other neurotransmitter imbalances.

Furthermore, depression is also connected to conditions like inflammation and the structural brain changes resulting from trauma or chronic stress — all of which could be the real cause of the imbalances. Ultimately, there are a wide net of influences contributing to whether or not a person gets trapped by depression, including:

  • Genetics
  • Physical illness
  • Chronic stress
  • Stressful life events
  • Past trauma
  • Physical pain
  • Social isolation
  • Other emotional disorders

With so many different avenues leading to depression, it should be no surprise that there is no single miracle cure for it. What ends up helping a person recover from depression is highly individual, and people who take a multi-pronged approach to recovery often have better results than those who depend on a single solution.

Neural Regeneration: Healing Your Brain

Although SSRIs cause an immediate spike in serotonin levels, it can take weeks before mood improves…if at all. So serotonin levels aren’t directly responsible for healing from depression — but what is?

It turns out that when people suffer from depression, a specific region of the brain can atrophy and even shrink — the area responsible for memory, learning and emotion (known as the hippocampus).

Fortunately, this unique part of the brain is also capable of recovering. It can grow new neurons and form new connections — a process called “neurogenesis” or “neural regeneration” — something we once thought only young brains were capable of. But research has since revealed the ability of our brains to change throughout our lives — an ability named “neuroplasticity.”

So, the real reason antidepressants work is that they actually stimulate neural regeneration in the hippocampus. This could be why antidepressants take weeks to kick in — brain neurons need time to heal, grow and form new connections. If this is news to you, that’s because the cutting edge of depression research right now is hippocampal neurogenesis.

What we’ve learned so far is that although antidepressants can help to stimulate neural regeneration, a wide variety of other lifestyle choices and supplements can also help with this process.

How CBD Stimulates Neural Regeneration

Cannabidiol recently gained FDA approval as a cannabis-derived drug to treat epileptic seizures. According to researchers, the major reason it works for seizures is that CBD protects neurons in the hippocampus — the exact brain area that is atrophied in depressed people — and there’s interesting evidence from both animal and human research:

Scientists think CBD could protect or regenerate the hippocampus via the following pathways:

 

It’s one thing to prove that CBD helps protect and grow neurons (which it does) — but proving that it can be useful for treating a disease as complex as depression will be difficult. Although large-scale human trials are not available yet, some preliminary evidence is promising:

  • Experimental evidence — Clinical trials are currently underway to examine CBD’s effectiveness at relieving anxiety, and anxiety can be a major contributor to depression. Although we lack controlled experiments testing CBD as a treatment for depressed humans, pre-clinical experiments on rodents have been promising. CBD helped relieve depression in rats, even when they also suffered from diabetes. However, this benefit wasn’t immediate: Scientists had to give them a few doses of CBD, starting 24 hours before testing. Another study found that a single dose of CBD had rapid antidepressant effects on both mice and rats, lasting up to 7 days after the treatment. Additionally, in mice, CBD’s antidepressant effects are even more effective when combined with an SSRI(In case you’re curious how scientists measure rodent depression…the most common experiment is to place mice or rats in deep water and record how long they keep swimming. The ones that give up faster are considered depressed. Don’t worry — the scientists don’t let them drown.)
