Happiness and Depression Could Be Steered By the Same Genes

Happiness and Depression Could Be Driven By the Same Genes

Genes are the secret-keepers. Within their tiny walls are so many answers to the whys and the whats of our physical and mental health. Our genetics though, are only one part of our story – and they may not have as much power to write our script as we may have once thought.

The more we learn about mental health, the more we realise the importance of the interaction between nature (genetics) and nurture (the environment). There is no single gene that ‘causes’ mental ill-health. If there was, everyone with the gene variation would go on to develop the symptoms that are associated with it. 

So if genes aren’t the full story, what’s missing?

There are genes that influence the onset of symptoms, but genes are not destiny. The key is the environment. If someone has a genetic vulnerability for mental ill-health, an adverse environment can steer this vulnerability in ways that compromise mental health. What’s fascinating, and gives us reason for optimism, is that a more positive, supportive environment can steer the same genetic vulnerability in ways that strengthen mental health. 

In a study published in the journal, Molecular Psychiatry, researchers have explained that the genes involved in mental ill-health could also nurture greater mental resilience. Someone with a genetic vulnerability to depression, for example, will do worse in a harmful environment than people without the genetic vulnerability, but in healthy, positive environments, they may do better than those without the vulnerability. 

‘If you take a gene that is linked to mental illness, and compare people who have the same genetic variant, it becomes clear that what happens to their mental health is based on their environment.’ – Professor Elaine Fox, Oxford University.

The same gene can work for us or against us. What’s that about?

Researchers suggest that the environment switches on a genetic vulnerability through its influence on our cognitive biases. These are the mental filters that we tend to look at the world through. 

‘Cognitive biases are when people consistently interpret situations through particular mental ‘filters’ – when people have a cognitive bias that emphasizes negative aspects or thoughts, they are more at risk of mental health disorders.’ – Professor Chris Beevers, University of Texas, Austin.

Someone with a negative cognitive bias will be more likely to turn their attention to threat or negative information. In situations that are neutral or ambiguous, a negative cognitive bias will interpret or explain those situations negatively.

If a friend is running late, for example, someone with a negative cognitive bias might interpret this as evidence that the friend doesn’t really want to be there. Someone with a positive cognitive bias, for example, might be more likely to explain the same situation as the friend was unexpectedly held up and that it was nothing to do with wanting to be there. 

Think of cognitive biases as looking through a stained glass window. If the glass is blue, we will see the world outside with a blue tinge. If the glass is covered in dust, we will see the world as a dusty one. If the glass is clear, this will be our view of the world and the people who come close enough to the window for us to notice. Depending on the environment, genes can change the ‘window’ through which we see the world. A positive environment will give us a positive view, a negative one will muddy it.

‘… some genes can make people more sensitive to the effects of their environment – for better or worse … If you have those genes and are in a negative environment, you are likely to develop the negative cognitive biases that lead to mental disorders. If you have those genes but are in a supportive environment, you are likely to develop positive cognitive biases that increase your mental resilience.’ – Professor Elaine Fox.

What is it about an environment that causes breakage?

More research is needed to understand the relationship between genetic vulnerabilities and environmental ‘switches’. There is a call to combine research about mental health genetics and research about cognitive biases. There is plenty of research about each separate field, but after reviewing a number of studies, researchers are convinced that the key to understanding more about our mental health, and more importantly how to manage it, lies in the merging of the two. 

What does it all mean? 

We all have our fault lines – the vulnerabilities that are part of being human. When those vulnerabilities are genetic, they will often stay hidden. Our only clue will be the symptoms they give life to, most likely when our environment gives them a push.

Our genes are our environment are deeply connected. We can’t change our genes, but we can influence our environment. This doesn’t mean that all that is needed for strong mental health is a change of environment. Even if it was that simple – which it’s not – changing the environment isn’t always possible. 

Further research is needed to understand the relationship between genes, the environment, and mental health. What we know for certain is that the environment around us matters, for better or worse. The people around us, the family we grew up in, our physiology, our work culture, the food we eat, the quality and quantity of sleep and exercise we get, the air we breathe, the pollutants and toxins we are exposed to – it all matters.

Anything you can do to make your environment better for you will be important:

  1. Toxic people will contaminate your self-esteem and the way you view the world. Whenever you can, show them the door. Now slam it shut behind them. Now check it to make sure it’s locked. Done? Good. Great. You’ve probably been wanting to that for a while. 
  2. Get plenty of exercise. This will increase vital neurochemicals and help to build the structure of the brain for the better, protecting and promoting stronger mental health. 
  3. Sleep. Your brain loves it like a favourite thing.
  4. Spend time deliberately focusing on positive things. It’s easy to get swamped by the bad, but when you can focus on something that stirs up the feel-good, it will change the structure of your brain for the better. It doesn’t have to be anything big – a text message that makes you happy, a feeling, a photo, a memory – anything that stirs something lovely in you. 20 seconds is enough to start the rewiring. Read more about that here. 

And finally …

Researchers are looking deeper into the combined influence of genetics and the environment on our mental filters. The hope is for a greater understanding of how genetics and the environment interact to affect our mental health. The more we can widen our knowledge, the more this will open up the way for effective treatment and management options, and ways to nurture mental health and mental resilience for all of us.

I needed this.
Is it true that Depression usually skips a generation ?
My kid swears I bi polar I am not.
I am still here because of you !

Barbara I’m so pleased you found this. We’re still not sure how the genetics of depression work, but it seems that there are genes that make people more likely to get depression. Not everyone who has the gene that makes them vulnerable to depression, will go on to get depression. It depends a lot on the environment – stress, the family you grew up in, the relationships around you, the food you eat, the air you breathe, the chemicals and toxins you’re exposed to and of course physical things like chronic pain will also make a difference. This means that it could easily skip a generation or a few generations. It could also be in some families but not others of the same generation. They’re getting closer to understanding it though and closer to finding a cure. I’m so pleased you’re still here. Stay. You are needed and wanted and important. Keep fighting for you.

Sometimes needs will come into being like falling stars - gently fading in and fading out. Sometimes they will happen like meteors - crashing through the air with force and fury. But they won’t always look like needs. Often they will look like big, unreachable, unfathomable behaviour. 

If needs and feelings are too big for words, they will speak through behaviour. Behaviour is the language of needs and feelings, and it is always a call for us to come closer. Big feelings happen as a way to recruit support to help carry an emotional load that feels too big for our kids and teens. We can help with this load by being a strong, calm, loving presence, and making space for that feeling or need to be ‘heard’. 

When big behaviour or big feelings are happening, whenever you can be curious about the need behind it. There will always be a valid one. Meet them where they without needing them to be different. Breathe, validate, and be with, and you don’t need to do more than that. 

Part of building resilience is recognising that some days and some things are rubbish, and that sometimes those days and things last for longer than they should, but we get through. First we feel floored, then we feel stuck, then we shift because the only choices we have we have are to stay down or move, even when moving hurts. Then, eventually we adjust - either ourselves, the problem, or to a new ‘is’. 

But the learning comes from experience. They can’t learn to manage big feelings unless they have big feelings. They can’t learn to read the needs behind their feelings if they don’t have the space to let those big feelings come back to small enough so the needs behind them can step forward. 

When their world has spikes, and when we give them a soft space to ‘be’, we ventilate their world. We help them find room for their out breath, and for influence, and for their wisdom to grow from their experiences and ours. In the end we have no choice. They will always be stronger and bigger and wiser and braver when they are with you, than when they are without. It’s just how it is.♥️
When kids or teens have big feelings, what they need more than anything is our strong, safe, loving presence. In those moments, it’s less about what we do in response to those big feelings, and more about who we are. Think of this like providing a shelter and gentle guidance for their distressed nervous system to help it find its way home, back to calm. 

Big feelings are the way the brain calls for support. It’s as though it’s saying, ‘This emotional load is too big for me to carry on my own. Can you help me carry it?’ 

Every time we meet them where they are, with a calm loving presence, we help those big feelings back to small enough. We help them carry the emotional load and build the emotional (neural) muscle for them to eventually be able to do it on their own. We strengthen the neural pathways between big feelings and calm, over and over, until that pathway is so clear and so strong, they can walk it on their own. 

Big beautiful neural pathways will let them do big, beautiful things - courage, resilience, independence, self regulation. Those pathways are only built through experience, so before children and teens can do any of this on their own, they’ll have to walk the pathway plenty of times with a strong, calm loving adult. Self-regulation only comes from many experiences of co-regulation. 

When they are calm and connected to us, then we can have the conversations that are growthful for them - ‘Can you help me understand what happened?’ ‘What can help you so this differently next time?’ ‘How can you put things right? Do you need my help to do that?’ We grow them by ‘doing with’ them♥️
Big feelings, and the big behaviour that comes from big feelings, are a sign of a distressed nervous system. Think of this like a burning building. The behaviour is the smoke. The fire is a distressed nervous system. It’s so tempting to respond directly to the behaviour (the smoke), but by doing this, we ignore the fire. Their behaviour and feelings in that moment are a call for support - for us to help that distressed brain and body find the way home. 

The most powerful language for any nervous system is another nervous system. They will catch our distress (as we will catch theirs) but they will also catch our calm. It can be tempting to move them to independence on this too quickly, but it just doesn’t work this way. Children can only learn to self-regulate with lots (and lots and lots) of experience co-regulating. 

This isn’t something that can be taught. It’s something that has to be experienced over and over. It’s like so many things - driving a car, playing the piano - we can talk all we want about ‘how’ but it’s not until we ‘do’ over and over that we get better at it. 

Self-regulation works the same way. It’s not until children have repeated experiences with an adult bringing them back to calm, that they develop the neural pathways to come back to calm on their own. 

An important part of this is making sure we are guiding that nervous system with tender, gentle hands and a steady heart. This is where our own self-regulation becomes important. Our nervous systems speak to each other every moment of every day. When our children or teens are distressed, we will start to feel that distress. It becomes a loop. We feel what they feel, they feel what we feel. Our own capacity to self-regulate is the circuit breaker. 

This can be so tough, but it can happen in microbreaks. A few strong steady breaths can calm our own nervous system, which we can then use to calm theirs. Breathe, and be with. It’s that simple, but so tough to do some days. When they come back to calm, then have those transformational chats - What happened? What can make it easier next time?

Who you are in the moment will always be more important than what you do.
How we are with them, when they are their everyday selves and when they aren’t so adorable, will build their view of three things: the world, its people, and themselves. This will then inform how they respond to the world and how they build their very important space in it. 

Will it be a loving, warm, open-hearted space with lots of doors for them to throw open to the people and experiences that are right for them? Or will it be a space with solid, too high walls that close out too many of the people and experiences that would nourish them.

They will learn from what we do with them and to them, for better or worse. We don’t teach them that the world is safe for them to reach into - we show them. We don’t teach them to be kind, respectful, and compassionate. We show them. We don’t teach them that they matter, and that other people matter, and that their voices and their opinions matter. We show them. We don’t teach them that they are little joy mongers who light up the world. We show them. 

But we have to be radically kind with ourselves too. None of this is about perfection. Parenting is hard, and days will be hard, and on too many of those days we’ll be hard too. That’s okay. We’ll say things we shouldn’t say and do things we shouldn’t do. We’re human too. Let’s not put pressure on our kiddos to be perfect by pretending that we are. As long as we repair the ruptures as soon as we can, and bathe them in love and the warmth of us as much as we can, they will be okay.

This also isn’t about not having boundaries. We need to be the guardians of their world and show them where the edges are. But in the guarding of those boundaries we can be strong and loving, strong and gentle. We can love them, and redirect their behaviour.

It’s when we own our stuff(ups) and when we let them see us fall and rise with strength, integrity, and compassion, and when we hold them gently through the mess of it all, that they learn about humility, and vulnerability, and the importance of holding bruised hearts with tender hands. It’s not about perfection, it’s about consistency, and honesty, and the way we respond to them the most.♥️

Anxiety and courage always exist together. It can be no other way. Anxiety is a call to courage. It means you're about to do something brave, so when there is one the other will be there too. Their courage might feel so small and be whisper quiet, but it will always be there and always ready to show up when they need it to.
⁣
But courage doesn’t always feel like courage, and it won't always show itself as a readiness. Instead, it might show as a rising - from fear, from uncertainty, from anger. None of these mean an absence of courage. They are the making of space, and the opportunity for courage to rise.
⁣
When the noise from anxiety is loud and obtuse, we’ll have to gently add our voices to usher their courage into the light. We can do this speaking of it and to it, and by shifting the focus from their anxiety to their brave. The one we focus on is ultimately what will become powerful. It will be the one we energise. Anxiety will already have their focus, so we’ll need to make sure their courage has ours.
⁣
But we have to speak to their fear as well, in a way that makes space for it to be held and soothed, with strength. Their fear has an important job to do - to recruit the support of someone who can help them feel safe. Only when their fear has been heard will it rest and make way for their brave.
⁣
What does this look like? Tell them their stories of brave, but acknowledge the fear that made it tough. Stories help them process their emotional experiences in a safe way. It brings word to the feelings and helps those big feelings make sense and find containment. ‘You were really worried about that exam weren’t you. You couldn’t get to sleep the night before. It was tough going to school but you got up, you got dressed, you ... and you did it. Then you ...’
⁣
In the moment, speak to their brave by first acknowledging their need to flee (or fight), then tell them what you know to be true - ‘This feels scary for you doesn’t it. I know you want to run. It makes so much sense that you would want to do that. I also know you can do hard things. My darling, I know it with everything in me.’
