Remarkable New Research About Stress and the Brain

Remarkable New Research About Stress and the Brain

In a perfect world, stress would come with an adjustable dial. And there would be six day weekends. And coffee, beds and breakfasts would make themselves. What we lack in adjustable dials and the automated making of beautiful things, we make up for in creativity and adaptability, and a profound capacity to protect ourselves from the assault of stress. 

We might not be able to stop the stress, but we can stop it causing ruin. New research explains why giving ourselves priority needs to become less of an option and more of a must do.

Relationships, money, children, work, and day to day life stress mean that it’s not always possible to adjust the volume and intensity of stress in our lives. What we can do is manage it, but tending to our own needs often doesn’t make it anywhere near the ‘must do’ list, hovering instead on the ‘maybe one day when I get a cheque six million dollars and don’t have to work or buy my own groceries’ list. If you have ever needed a reason to get serious about taking time out to de-stress, remarkable new research has something for you.

Stress and the brain. What they found.

The research by Rockefeller University was conducted on mice, but don’t let that take anything away from the findings and what they mean for us humans. Mice are often used in studies because they are so genetically, biologically and physiologically close to humans. 

In the study, published in the journal, Molecular Psychiatry, researchers exposed the mice to chronic stress by keeping them in a small space for 21 days. They then looked at the mice to see which of their behaviours had changed. They were also interested to see whether there were any changes in the brain cells within the three different areas of the amygdala, the part of the brain that regulates emotions such as fear and anxiety. 

The exposure to chronic stress caused changes in the amygdala. These changes have been associated with anxiety and depression. 

In the first area of the amygdala the researchers looked at, the stress did not appear to cause any noticeable changes.

In the second area, they noticed the branches of the cells had become longer and more complex. This is a healthy change and points to the ability of the mice to adapt to certain environments.

In the third area, they noticed shrinkage of the branches that connected with other parts of the brain. This change is a worrying one. When these crucial connections are lost, the brain is less able to adapt to new experiences. Effectively, it becomes trapped in an anxious or depressed state.

Protecting the Brain.

The research also highlighted a new experimental drug that might protect the brain against these changes. 

‘While this rewiring from chronic stress can contribute to disorders such as anxiety and can contribute to disorders such as anxiety and depression, our experiments with mice showed that the neurological and behavioral effects of stress can be prevented with treatment by a promising potential antidepressant that acts rapidly.’ Carla Nasca, researcher.

The treatment that was used to protect against the effects of chronic stress was acetyl carnitine, a molecule that is being explored for its potential as a rapid-acting antidepressant. The mice who were treated with this drug were more sociable and showed less adverse brain changes, than the stressed mice who weren’t treated. Humans and mice both naturally produce acetyl carnitine. Animals that are more vulnerable to depression show a deficiency in acetyl carnitine. Researchers are looking into whether people with depression show the same abnormally low levels.  

Here’s the rub. As with any physiological symptom, the symptoms of stress are a sign that something needs changing. Chronic stress is a sign that the environment is drawing on more emotional, physical and/or physiological resources than you have. 

The promise of the experimental medication is that is will protect the brain from the neurological effects of stress that we know about, but it doesn’t get rid of the stress. Stress has other effects on the body and mind, outside the brain.

Of course, it’s not always possible to change your life, which is why protecting your whole self from the effects of stress is so important. Medication may be one part of the answer, but it’s certainly not all of it, nor is it the only one. 

If I can’t reduce stress in my life, what then?

Ok. So you can’t leave you job, your relatives, your bills, the traffic and the nailbiting ups and downs of The Great British Bake Off (for the love of lemons why does anyone have to leave?) – what can you do instead?

A powerful way to protect against stress is to reframe it. Research from Harvard has found that reframing stress as helpful rather than harmful can reverse the physiological changes brought about by stress. 

In a massive study that involved almost 30,000 people, researchers found that people who experienced high stress and who believed that it was harmful for them, had a 43% increase in the risk of premature death. However – people who were highly stressed but didn’t believe that it would harm them had a risk of premature death that was even lower than people who claimed they had a pretty low-stress existence.

And finally …

Stress and modern living often tend to come as a bundle. If we can’t change the stressors that cozy up beside us day after day, we need to change the way we deal with them. There are many life-giving ways to put back what stress takes out, including exercise, reframing the way we think about stress, sleeping, playing, connecting with our crew, listening to music, or meditating. The challenge then, becomes finding ways or opportunities to become our own priority from time to time. Life opens up when we love ourselves as much as we love the ones close to us.

Do you have the name of the research that looked at how amygdala responded to stress and illustrations to the shrinkage of branches?

quite understandable and pretty informative…..like the article,because I’ve been also suffering from stress…keep sharing more article about stress….Thank you for your lovely article .

And so much of what we stress about is imagined in our mind. The mind is such an awesome resource, and our imagination is best used to rehearse positive outcomes. Why waste our power on negative thinking? Ten minutes a day in mental rehearsal (how might today turn out if everything goes great?) can give us such a huge boost – without drugs! Try this for just three days in a row and see what happens!

What I love about the viewpoints of these articles is the positive slant on things. Many of us have -including me -come from a very dysfunctional and psyche damaging environment leaving us with a constant “flight or fight” reaction to most things. The exciting and promising part of the brain is in its plasticity and ability to alter pathways to a brain able to heal and cope better. It’s not an easy task and I wholeheartedly embrace the self love ideology towards oneself to offset situations that aren’t easily changed. A 10 minute break at a park or an outdoor patio gives us that often overlooked but oh so necessary recharge. Today -I’m getting my hair done and going for a iced lime slushy drink at my fave diner. Remember to be good to you??

I also meant to ask about voice decibel levels A co-worker who is at the front desk (my office is next to it) literally screeches at the top of her lungs day in and day out. how does that affect brain and body function?

Great Article! We forget in the intensity of stress that little things can help us feel better and making deliberate steps to put them in place is sometimes needed. Thanks for keeping these coming – there’s always something for everyone. I look forward to my Friday in-box!

“Stress and modern living often tend to come as a bundle”

Absolutely! Stress & emotional reactions are an integral part of our being human. We stress, therefore we are. Stress means we’re alive!

Like the article notes though. It’s how we interpret and manage the stress that’s most important. Like the Godfather of stress Hans Selye said decades ago:

“It’s not stress that kills us, it is our reaction to it”.

Thanks for the great article.

Would like to have heard of some more natural ways to reduce stress other than medication. Those areas should always be introduced first. Medication should always be a last resort.

Debbie there are a number of articles on the site that talk about the natural ways to reduce stress. The scope of this article was this piece of research that explored the effects of stress on the brain. As part of that research, they looked at the effect of a particular medication on those changes in the brain but as the article points out, there are other considerations in relying on medication to turn around the effects of stress on the brain. At the bottom of the article is a suggested article, ‘How to be Mindfully Selfish and why It’s So Important’. This article discusses medication-free ways to manage stress.

Just in time before my first psychotherapy appointment on Monday. Thank you Karen, this is most helpful.
I was always convinced that stress and depression are connected, and if the biggest stressors were removed, the depression would not flare up.
Despite my depression being there constantly, the absolute lowness of spirits only becomes apparent if there are too many stressful episodes happening at the same time, or so close together that I cannot deal with them simultaneously.
Could it be that just one simple chemical was able to restore the balance?
If so, it would be marvellous – I hate the idea of antidepressants and how they alter personality.

You’re welcome Monique. I’m pleased the article found it’s way to you when it did. Stress can certainly feed into depression. There is definitely a link there. A lot of research is looking at depression as being caused by systemic inflammation, which stress can contribute to. Here is an article that explains that https://www.heysigmund.com/new-research-will-change-way-think-depression/. This is why lifestyle factors, such as exercise, eating the right food to support brain health, reducing stress, sleep, sunlight, social connection, meditation etc are all important for mental health and keeping the vital neurochemicals at healthy levels. Even doing these things though, sometimes depression can happen, so there is still a lot we need to learn about the causes. There is a lot of work happening in the area, which is great news. Hopefully some answers and a reliable, effective way to treat depression aren’t too far away.

Thanks so much @maggiedentauthor♥️…
“Karen Young - Hey Sigmund has such a wonderful way with words especially around anxiety. This is her latest beautiful picture book that explains anxiety through the lens of the Polyvagal theory using the metaphor of a house. This shows how sometimes anxiety can be hard to notice. I think this book can help kids and teens better understand stress and anxiety. I loved it! This would be great for homes, schools and in libraries.
Congratulations Karen.💛”
Of course we love them, no matter what - but they need to feel us loving them, no matter what. Especially when they are acting in unlovable ways, or saying unlovable things. Especially then.

This is not ‘rewarding bad behaviour’. To think this assumes that they want to behave badly. They don’t. What they want is to feel calm and safe again, but in that moment they don’t have the skills to do that themselves, so they need us to help them. 

It’s leading with love. It’s showing up, even when it’s hard. The more connected they feel to us, the more capacity we will have to lead them - back to calm, into better choices, towards claiming their space in the world kindly, respectfully, and with strength. 

This is not about dropping the boundary, but about holding it lovingly, ‘I can see you’re doing it tough right now. I’m right here. No, I won’t let you [name the boundary]. I’m right here. You’re not in trouble. We’ll get through this together.’

If you’re not sure what they need, ask them (when they are calm), ‘When you get upset/ angry/ anxious, what could I do that would help you feel loved and cared for in that moment? And this doesn’t mean saying ‘yes’ to a ‘no’ situation. What can I do to make the no easier to handle? What do I do that makes it harder?’♥️
Believe them AND believe in them. 

‘Yes this is hard. I know how much you don’t want to do this. It feels big doesn’t it. And I know you can do big things, even when it feels like you can’t. How can I help?’

They won’t believe in themselves until we show them what they are capable of. For this, we’ll have to believe in their ‘can’ more than they believe in their ‘can’t’.♥️
Sometimes it feels as though how we feel directs what we do, but it also works the other way: What we do will direct how we feel. 

When we avoid, we feel more anxious, and a bigger need to avoid. But when we do brave - and it only needs to be a teeny brave step - we feel brave. The braver we do, the braver we feel, and the braver we do… This is how we build brave - with tiny, tiny uncertain steps. 

So, tell me how you feel. All feelings are okay to be there. Now tell me what you like to do if your brave felt a little bigger. What tiny step can we take towards that. Because that brave is always in you. Always. And when you take the first step, your brave will rise bigger to meet you.♥️

If anxiety has had extra big teeth lately, I know how brutal this feels. I really do. Think of it as the invitation to strengthen your young ones against anxiety. It’s not the disappearance of brave, or the retreat of brave. It’s the invitation to build their brave.

This is because the strengthening against anxiety happens only with experience. When the experience is in front of you, it can feel like bloodshed. I know that. I really do. But this is when we fight for them and with them - to show them they can do this.

The need to support their avoidance can feel relentless. But as long as they are safe, we don’t need to hold them back. We’ll want to, and they’ll want us to, but we don’t need to. 

Handling the distress of anxiety IS the work. Anxiety isn’t the disruption to building brave, it’s the invitation to build brave. As their important adult who knows they are capable, strong, and brave, you are the one to help them do that.

The amygdala only learns from experience - for better or worse. So the more they avoid, the more the amygdala learns that the thing they are avoiding is ‘unsafe’, and it will continue to drive a big fight (anger, distress) or flight (avoidance) response. 

On the other hand, when they stay with the discomfort of anxiety - and they only need to stay with it for a little longer each time (tiny steps count as big steps with anxiety) - the amygdala learns that it’s okay to move forward. It’s safe enough.

This learning won’t happen quickly or easily though. In fact, it will probably get worse before it gets better. This is part of the process of strengthening them against anxiety, not a disruption to it. 

As long as they are safe, their anxiety and the discomfort of that anxiety won’t hurt them. 
What’s important making sure they don’t feel alone in their distress. We can do this with validation, which shows our emotional availability. 

They also need to feel us holding the boundary, by not supporting their avoidance. This sends the message that we trust their capacity to handle this.

‘I know this feels big, and I know you can do this. What would feel brave right now?’♥️
