How long does it take to heal a dysregulated nervous system? What decides the timeline, with Dr. Aimie Apigian
Episode 196. A solo episode of The Biology of Trauma® podcast with Dr. Aimie Apigian.
There is no set number of months or years. How long it takes to heal a dysregulated nervous system depends on how long your nervous system has lived this way and how far your body has adapted, including whether a chronic illness has developed. You can tell it is healing by how it responds to change: less overreacting, less underreacting, and more ability to move into stress and come back out of it.
People want a number. Six months, two years, ten years. Something they can plan around.
Dr. Aimie Apigian hears this question more than any other, and in this solo episode she answers the question underneath it. How would you know it is working? And what decides how long it takes?
Dr. Aimie is a double board-certified physician in preventive medicine and addiction medicine and the author of The Biology of Trauma. She walks through what dysregulation actually is, why it never exists on its own, and the principle from the ICU that explains why long-standing patterns have to change slowly.
There is no set timeline for healing a dysregulated nervous system. It depends on how long the nervous system has lived in dysregulation and how far the body has adapted, including whether disease has developed. Healing means moving toward a nervous system that can go in and out of its states as it was designed to, which is different from feeling calm all the time. Because dysregulation grows out of disconnection, disruption and depletion, you can track healing through all four patterns, and biology sets the ceiling on how fast change can happen.
What does it mean to heal a dysregulated nervous system?
It means movement toward a more regulated nervous system. "Healing is the process of change towards health," Dr. Aimie explains, so healing here is a direction you are moving in rather than a finish line.
A regulated nervous system does not stay calm all the time. Regulation is the ability to go in and out of the states as the nervous system was designed to: into stress when stress is needed, and back out again. A healthy nervous system helps us grow, expand, become more embodied and more present, and move toward emotional, mental and physical health.
What is nervous system dysregulation?
Dysregulation is a pattern in how the nervous system responds to change. It either overreacts or underreacts, and rarely responds in proportion to what the moment calls for.
The nervous system is constantly adapting to change, both outside the body (a hot day that sets off sweating) and inside it (blood sugar, blood pressure, sodium and potassium levels). Dr. Aimie offers a simple picture. When a fire alarm goes off in a building, some people overreact, some respond in proportion, and some underreact and stay in their seats. Your nervous system does the same with every change in your life, whether that change is emotional, physical or something someone says to you.
Dysregulation: a pattern in which the nervous system overreacts or underreacts to change rather than responding in proportion to it. It develops when the nervous system is stuck in danger mode, seeing danger even when there is none.
Why does dysregulation never exist on its own?
Because dysregulation comes out of a nervous system stuck in danger mode, and that same state produces other patterns alongside it.
When the body's trauma response is never resolved, the nervous system does not return to a sense of safety. Even when the danger is logically over, it stays on guard in case it happens again. It loops between the two survival states, the stress response and the trauma response, and rarely lands in true safety. Dr. Aimie calls this the body trauma loop.
Body trauma loop: the cycle a nervous system falls into when a trauma response was never resolved. It moves between the stress response and the shutdown of the trauma response and rarely returns to safety, because it expects the danger to happen again.
How does the body's trauma response create these patterns?
Each survival strategy the body uses in a trauma response becomes a chronic pattern when the trauma stays unresolved.
Dissociation becomes disconnection. A disconnection from yourself, from your reality, and from what you would really want to do.
Immobilization becomes disruption. The freeze response puts on all the brakes. Over time that shows up as feeling stuck: repeating the same behaviors, doing the same things you don't want to do.
Energy conservation becomes depletion. The body dims its metabolism so it cannot be seen, heard or felt, with the thyroid and mitochondria helping. Over time, that feels like always being low on energy.
Dysregulation is the fourth pattern, and it grows out of the first three. When you feel disconnected, stuck and depleted, one new problem is too much. Of course the nervous system either overreacts or underreacts.
What are the signs your nervous system is healing?
Watch how you respond to change, and watch the three patterns that feed dysregulation. Dr. Aimie offers four questions:
When something changes, do I overreact, underreact, or respond in proportion?
What is my sense of connection, to myself, my life and others?
What is my sense of forward movement in my life?
What is my sense of energy, compared with my sense of depletion?
"We're not wanting to just focus on the dysregulation," she says, "but we're wanting to focus on what creates the dysregulation, because then that's how the dysregulation will shift."
What is the fifth pattern of stored trauma?
The fifth pattern is disease. It is the body's adaptation to living with dysregulation over time, and it is the subject of chapter 10 of The Biology of Trauma.
Chapter 10 opens with a line from Dr. Vincent Felitti, co-principal investigator of the original Adverse Childhood Experiences Study: "What you think is the problem, has been the solution to the problem." Dr. Aimie asks listeners to see dysregulation the same way. The autoimmunity, the digestive issues, the skin issues and the hormone issues may be the result of decades spent adapting to a nervous system that is always sensing danger. In her framework, the diseases associated with adverse childhood experiences are diseases of dysregulation. She sums it up as an equation: dysregulation times time equals disease.
How long does it take to heal a dysregulated nervous system?
There is no single number, because the timeline depends on how long the nervous system has lived this way and how far the body has adapted to it.
Dr. Aimie describes a sequence. The first three patterns create dysregulation over time, and dysregulation over time creates disease. If a chronic health issue is present, the body has adapted to dysregulation more deeply than if disease has not developed yet.
She saw this in her early work with adopted and fostered children who had severe trust issues. Even when their dysregulation was severe, their nervous systems shifted faster than an adult's, and much faster than an adult living with chronic illness, because there had been fewer years of their biology adapting. By the time an adult reaches a diagnosis, the nervous system has lived this way for so long that "this way now feels the safest way."
Why does long-standing dysregulation have to change slowly?
Because a nervous system that has adapted to something for a long time has to readjust every connected system, and a large change made too fast is itself dangerous.
Dr. Aimie learned this as a resident, admitting a patient to the ICU with a sodium level of 121. The longer the sodium had been low, the slower the correction had to go, because the kidneys, the adrenal glands and the heart had all adjusted to that level and would all have to readjust. Correcting a long-standing low sodium too quickly can damage the protective coating of nerve cells in the brain, a serious injury called osmotic demyelination. The body needs time to adapt to the new level. The same principle applies to stored trauma. The longer it has been there, the more the nervous system needs pacing for change to feel safe.
Why is biology the most neglected piece of nervous system repair?
Because your biology creates the ceiling effect: it sets how fast you can create change and have it feel safe enough.
Healing a dysregulated nervous system means working at several layers: parts, somatic memory, and biology. The biology is the one most often left out. If your body is still in energy conservation, it treats all change as too much. Dr. Aimie describes what happens after a good therapy session in that state. The nervous system would like to integrate it, it doesn't have the energy, so it goes back to doing what it has always done, because that takes the least energy to keep you alive.
This is why she may bring in support for the mitochondria early. In her practice, magnesium is a common example. When people start supplementing, she sees greater shifts in their therapy sessions, because a better-resourced nervous system experiences change as safer.
Ceiling effect: the limit your biology places on how much change your nervous system can integrate. When cells are depleted or still conserving energy, even good therapeutic work has trouble holding.
Key Takeaways
The timeline depends on how long the nervous system has lived in dysregulation and how far the body has adapted.
Healing a dysregulated nervous system means moving toward a nervous system with healthy responses.
Regulation means the nervous system can move in and out of its states as designed. It does not mean staying calm all the time.
Dysregulation is a pattern in how the nervous system responds to change: overreacting or underreacting.
Dysregulation never exists on its own. It grows out of disconnection, disruption and depletion.
You can track healing through all four patterns: reactions to change, connection, forward movement and energy.
The fifth pattern, disease, is the body's adaptation to dysregulation over time.
Children's nervous systems often shift faster than adults', because their biology has had fewer years to adapt.
Biology sets the ceiling on how fast change can happen, and it is the most neglected piece of repair.
Repair is possible at any age.
Notable Quotes
"Healing is the process of change towards health. And so healing a dysregulated nervous system looks like the movement towards a more regulated nervous system."
"More regulated nervous system does not mean it is always calm... Regulation is the health of the nervous system to be able to go in and out of the states as it was designed to do."
"Dysregulation is a feature of the nervous system, it's a pattern of the nervous system, of how it responds to change."
"Dysregulation is a pattern of the nervous system stuck in danger mode. Meaning it sees danger even when there's not actually danger."
"Dysregulation is the natural byproduct of being disconnected, feeling stuck and powerless and trapped, and feeling like you have little energy to put into new problems."
"We're not wanting to just focus on the dysregulation, but we're wanting to focus on what creates the dysregulation, because then that's how the dysregulation will shift."
"We think the autoimmunity, we think that the digestive issues, we think that the skin issues, we think that the hormone issues are the problem. What if they are actually the decades of adapting to living with a dysregulated nervous system?"
"We're talking about decades of adaptations happening underneath the surface. It's not like it's not happening, then one day, poof, it comes out of nowhere. It's been happening all along."
"The longer that the nervous system has lived this way, the slower that change has to go in order for the nervous system to integrate that change over time."
"The biology piece is the most neglected piece in the nervous system dysregulation repair. And yet, your biology is what's really creating the ceiling effect for how fast you can create that change and that healing and have it feel safe enough."
"What I really want to leave with you is the hope that I don't care how old you are, repair can always happen. I have worked with people in their 70s, 80s, 90s."
Episode Takeaway
People ask me how long it is going to take, and I understand why. When you have been living in a body that overreacts or shuts down, you want a finish line to plan toward.
What I can give you is more useful than a number. I can give you a way to know you are moving.
Healing is the process of change towards health. So the question to keep asking is whether your nervous system is responding to change in a healthier way than it used to. Can you notice stress rising and come back down? Are there places in your life where you felt stuck that have started to move? Do you have a little more energy for the next problem than you did before?
These things can be measured. And they matter, because dysregulation never shows up by itself. It grows out of disconnection, stuckness and depletion. When you feel far from yourself, trapped and low on energy, of course your nervous system overreacts or underreacts, because every new problem is too much. When we work on connection, forward movement and energy, the dysregulation shifts with them.
The pace depends on how long your body has been living this way. A child who has lived in dysregulation for a few years can change quickly, even when the dysregulation is severe. An adult who has lived with it for decades has a biology that has reorganized around it. By the time there is a diagnosis, this way of living has come to feel like the safest way. That body needs change to come more slowly, so it can adapt without going back into danger.
I learned this principle in the ICU. You cannot correct a sodium level that has been low for a long time all at once. Every system has adjusted to it, and every system has to readjust. Stored trauma asks for the same respect.
This is also why I keep coming back to biology. Your biology sets the ceiling on how much change you can integrate. If your cells are still conserving energy, a great therapy session has nowhere to land, and your body goes back to what costs it the least. Supporting the biology is part of the healing work, and it is often the piece that lets everything else hold.
So here is where I would start. Get a picture of your patterns now, so you have something to measure against later. That is what the 2-Minute Assessment for Stored Trauma is for.
When you are ready to build the skills that shift these patterns, the Foundational Journey is where we lay that foundation: getting to know, feel, track and shift your body and its states, one small step every day, in the sequence of safety, support and expansion.
And please hear this. I have worked with people in their seventies, eighties and nineties. As long as you are alive, your nervous system is still working to keep you alive, and we can work with that nervous system.
Your pace is the right pace.
Frequently Asked Questions
How long does it take to heal a dysregulated nervous system?
There is no set number. It depends on how long the nervous system has lived in dysregulation and how far the body has adapted, including whether a chronic illness has developed.
Does a regulated nervous system mean feeling calm all the time?
No. Regulation is the ability to move in and out of states as the nervous system was designed to, including moving into stress when it is needed and coming back out.
Why do children's nervous systems change faster than adults'?
Dr. Aimie found that even children with severe dysregulation shifted faster than adults, because their biology had fewer years to adapt to it.
Can you heal a dysregulated nervous system at any age?
Yes. Dr. Aimie has worked with people in their 70s, 80s and 90s. As long as you are alive, your nervous system is still working to keep you alive, and it can be worked with.
Why does a good therapy session sometimes not stick?
Integration takes energy. If the body is still conserving energy, the nervous system goes back to what it has always done, because that takes the least energy.
What does dysregulation have to do with chronic illness?
In Dr. Aimie's framework, disease is the fifth pattern of stored trauma: the body's adaptation to dysregulation over time. She describes the diseases associated with adverse childhood experiences as diseases of dysregulation.
What does the 2-Minute Assessment for Stored Trauma measure?
It gives a quick picture of the patterns of unresolved stored trauma showing up in your life, your relationships and your body, including dysregulation.
