What many people fail to recognize is that anxiety attack symptoms are actually the result of the normal workings of the autonomic nervous system (ANS). It isn't that the nervous system has gone wacky - it's responding exactly as it should.
When folks arrive in my office after a series of visits to their doctor they are understandably concerned. Often, they haven't received a clear diagnosis from their physician. They don't yet realize that these symptoms are based in anxiety:
"I worry and worry about things that later seem unimportant."
"I go to sleep but my mind won't shut off."
"My chest is so tight, it sometimes feels as if I can't get a full breath."
"I've been washing my hand obsessively. I know its silly but I can't stop myself."
Even so, it's often missed in the offices of medical practitioners. Thousands seek help from their doctors for "other" health conditions that while similar to anxiety attack symptoms, are believed to be otherwise. (e.g dizziness is associated with low blood sugar, tightness in the chest with heartburn).
In situations such as these, the depth of the problem is not being assessed. Nor is the magnitude of the stressors impacting the individual being acknowledged. The problems are not being associated with anxiety and dysregulation of the nervous system.
You see, unlike the more chronic, long-standing feelings of anxiety, anxiety attacks symptoms occur suddenly and without warning (at least they appear to come out of nowhere).
It isn't that people actually tell their physician that they've had an anxiety attack, it's that the symptoms mimic so many other health problems. The mistaken conclusion is that the attack is related to some organic problem. For instance, anxiety attack symptoms are often confused with the symptoms of a heart attack.
Indeed, it is sometimes only after several visits to the emergency hospital that the true diagnosis of an anxiety attack becomes confirmed.
And unfortunately, sometimes anxiety is never diagnosed and the individual continues to believe they are suffering from some strange ailment that the doctors are baffled by. They never receive the proper treatment. Without a clear diagnosis they may even feel victimized by the medical establishment.
The main problem is that anxiety attack sufferers have had high activation for sometime without awareness. They have been living with high activation for so long, it has become their "norm". The anxiety attack then appears to arise without warning.
If the nervous system is dysregulated, it is almost inevitable that the activation will increase over time. This is a subtle process and for most people they have little awareness until their symptoms are "shouting" at them.
Let me explain.
Because the nervous system is constantly adapting to new states (see Tracking your Progress for more information), and the tension in the body easily finds a homeostasis (with each new state becoming the "norm"), inaccurate perceptions are inevitable. Folks miss the fact that their nervous systems have changed.
So even though the body has become more tense and dysregulated, the individual assumes "this is the way I have always been". An additional irony is that the anxiety sufferer feels more aware with their bodies and the aftereffects are a multitude of sensations that feel strange and uncomfortable.
[Don't get me wrong. They're not imagining these unpleasant sensations. Natural bodily processes even painful ones can seem weird when heightened. But this topic is worth discussing in more depth at a later point.]
Our nervous system evolved over thousands of years. For most of those years humans faced enormous dangers from animals, erratic food supplies, harsh weather conditions, and of course other human beings.
Our brain evolved to respond with lightning speed to any sign of danger, often even before we are even fully conscious of it.
This physical reaction was coined by Walter Cannon as the fight-or-flight response.
Imagine for a moment being alone in a cabin in the woods. You go out to the wood pile about 50 yards from the cabin door so you can light a fire.

One of the natural consequences of dysregulation is high activation (i.e. high levels of arousal). Moreover, the ways the nervous system copes with high levels of arousal is through dissociation (i.e. feeling less in one's body).
Dissociation is akin to a somatic numbing and will fluctuate depending upon challenges both internally (i.e. illness, PMS) and externally (i.e. day-to-day stressors). In other words, we can seamlessly move in and out of dissociation on a minute to minute, hour to hour or daily basis. For example, an individual might feel "relaxed" just before "suddenly getting an anxiety attack".
In actual fact, the "relaxed" state was dissociative, an experience that numbs body sensations. As these folks are momentarily (or otherwise) resourced and they move out of dissociation they feel an onslaught of panic and anxiety. This fluctuation can wreak havoc with one's sanity. It's crazy-making!
Not to mention...
The fear system is powered up by the reptilian brain. Not only can you learn how to control your fears - you can dramatically reduce them - and that means living anxiety-free. To learn more click the link below.

And behind the scenes...
What many people fail to recognize is that anxiety attack symptoms are actually the result of the normal workings of the autonomic nervous system (ANS). It isn't that the nervous system has gone wacky. It's responding exactly as it should.
The problem is that the set point for danger is too low. Too many events or too much stimulation easily trigger the system into emergency action.
And there's no mystery to why it's set too low...but I will explain that in my next article. (To learn more about the ANS you will find the following articles helpful: Parasympthetic Nervous System and the Sympathetic Nervous System).

The causes of anxiety attacks are rooted in our neurobiology. Anxiety is actually a normal human emotion that enables us to respond to danger in our environment. In short spurts and at the right time, anxiety is a good thing.
When an anxiety attack is triggered, hormones are released so we can respond quickly; in moderation, this helps us survive and to escape threatening situations.
However, if this automatic response is out of proportion to the threat, these emotions interfere with normal functioning and can dramatically affect the quality of our lives.
Even when your anxiety is out of proportion, the nervous system is working as it should. Surprised? Many people are when I tell them this. The problem is that your nervous system has learned to respond this way.
It was the right brain and in particular, the reptilian brain (the right brain includes large parts of the reptilian brain and the limbic system) that learned to respond this way. The reptilian brain is largely in charge of producing anxiety symptoms.
Our nervous system wiring has evolved over thousands of years and as I have described, it's like a high performance engine. It requires fine tuning.
Every trauma you ever experienced is recorded by your reptilian brain by raising your level of activation. If you think in terms of everyone buzzing internally at a different frequency then this frequency is called your level of activation. It's a measure of how wound up you are inside.
It's also an internal gauge for how much danger is perceived to be in the environment. How is this so?
Because, for every traumatic event1 we've experienced, the reptilian brain learns that the environment is dangerous. This learning will set the reptilain brain on a higher level of activation. It is currently felt that the earlier and the more traumatic your experiences, the deeper the learning and the higher your level of activation will be.
The higher your activation the more your reptilian brain will be on guard checking for signs of danger, only allowing you to let go when you are safe.
For some people that place of safety is never achieved because the level of activation is too high.
When we experience a sharp onset in our fear state Porges suggested that this sudden increase in excitation (or activation as it is often called) propells a compensatory reaction in the nervous system called the "dorsal brake".
The dorsal brake is initiated when high rates of heart beat, breath, blood pressure etc. reach intolerable levels that threaten survival. Most mammals cannot survive this sudden braking system and die as a result (i.e. the freeze response).
Because the human species has a developed cortex, we can use our intelligence to make sense of what just happened (i.e. with a traumatic event). That is of course, if our belief system does not sway us.
In the case of Voodoo Death, the individual's belief system does not provide the necessary meaning that might calm the individual down.
In fact, it is working the other way around. The individual's belief system is creating a fear state that increases a sudden rise in activation. The more dramatic the increase in activation, the more the dorsal brake is likely to come on (this has yet to be confirmed by research however although it might be hard to get subjects for this study).
A dysregulated nervous system is the basis for many of our phobic ('fear') responses. For instance, you don't need a bad experience with an elevator to develop a phobia to elevators. But if you happen to have high activation as the elevator door closes and the enclosed space raises your activation level, you could easily develop a phobic response. Your left brain "problem-solver" erroneously concludes that it was the elevator that posed the danger. [We draw these erroneous conclusions all the time but that's another topic for later.]
What complicates the identification of anxiety attack symptoms is that health problems--for similar reasons--increase the risk that you will trigger your threshold for danger. A health problem--no matter how small--threatens our survival and the higher our activation to begin with, the more we will feel its impact.
Let's say you've developed a bad cold and in the middle of your recovery you have an anxiety attack. It's not that your virus caused the anxiety attack. It was just the last thing your system could take. It "filled you up". It moved your system past your threshold for danger.
You see, it seems that the autonomic nervous system doesn't differentiate an internal threat (i.e. a health problem) from an external threat. This is what clinical practice is revealing. Neurobiolgically, it's understandable that anything that makes us vulnerable, intensifies our need for survival.
You may have felt you were doing "fine" before that virus kept you home, and without an alternative explanation for your anxiety attack you might naturally assume it came from the virus. However, it was the virus that caused your nervous system to max out the level of activation. It "filled you up" in much the same way as do traumatic events like car accidents, sudden losses, or bad falls.
Our primitive internal wiring (i.e. our reptilian brain) evolved over thousands of years during which time we existed as cave dwellers roaming the countryside and facing countless dangers. This reptilian part of our brain controls much more of our behaviour than we dare to think. If the nervous system "reads" danger through a high level of activation, we are not in the driver's seat.
In short, we can lower our level of activation. With reduced activation more of our cortical control rests in our hands. You see, it's our cortex (i.e. our cortical control) that calms us down, that tells the primitive brain, "don't worry, I can handle this".
The higher our activation however, the less cortical control we have and the more suseptible we are to the impulsive actions of our primitive brain. In plain English, this means even though I know the elevator isn't dangerous, I can't convince myself otherwise.
Yes, there are actual recorded deaths by voodoo. Cannon (who coined the term "Voodoo Death") was the first scientist to write seriously about the phenomenon. Cannon reasoned that these deaths by voodoo were the result of over-excitement.
At the time, Cannon was studying mammalian survival strategies. He hypothesized that voodoo death was due to the heightened arousal that get's triggered under extreme fear. This wired in propensity is called the "fight or flight response".
But most people probably know about Voodoo Death because of the James Bond movie about Caribbean Death and Voodoo (click through to see which movie title).
Cannon just about had it right. However, it is now believed that a "wired-in" survival strategy, the freeze response, is the explanation for Voodoo Death.
The fear system and mental health
One of the ideas that MyShrink promotes is that many of our mental health problems are rooted in the fear system (including fears related to our attachment history).
This fear system is based in the lower "reptilian" brain (i.e. brain stem and it's connections to the limbic system where the amygdala is located). Because it lies in the lower brain we don't typically have direct control over it (i.e. getting hungry, sleepy etc.)
But it is our higher brain--the prefrontal cortex--that allows us to ascribe meaning to events and to help calm us down so that we do not die from the freeze or immobility response... unless our beliefs are working against us...hence Voodoo Death.
"His cheeks blanch, and his eyes become glassy, and the expression of his face becomes horribly distorted. He attempts to shriek but usually the sound chokes in his throat, and all that one might see is froth at his mouth. His body begins to tremble and his muscles twitch involuntarily. He sways backward and falls to the ground, and after a short time he appears to be in a swoon. He finally composes himself, goes to his hut and there frets to death." R. H. Basedow (1925) The Australian Aboriginal
Cannon assumed that voodoo death was caused by over-activation of the sympathetic nervous system (i.e. like being over-excited).
David Lester, a researcher who later followed up on Cannon's work, proprosed another explanation. He suggested that the parasympathetic nervous system was the real culprit. The parasympathetic nervous system as you may know calms down the nervous system when we're ready to relax. This is known as the relaxation response, or what somatic practitioners refer to as the ventral vagal response.
Stephen Porges elaborated on his theory by explaining that it isn't the ventral vagal response that's at work in Voodoo Death. Porges uncovered another branch of the parasympathetic nervous system called the dorsal vagal branch which is triggered when we become overwhelmed.
BTW, his discovery of the dorsal branch has opened up a whole new area of study that sheds light on depression, PTSD, illness (Scaer, 2005) and even joy.
Do problems such as "fainting" and "nose bleeds" (possible evidence of the dorsal brake) appear more often in clients seeking therapy for anxiety, depression and PTSD? Is Porges' theory an explanation for them? Just possible. I've certainly seen a reduction in fainting episodes and nosebleeds in my practice as the nervous system becomes more regulated.
Somatic therapists are certainly rejoicing. Porges' theory explains what we see in our clinical practices. When you reduce fear in the nervous system, so called "pathology" disappears. This is a generalization but I continue to be amazed at the power of the somatic approach to anxiety, depression and issues related to developmental gaps (which pretty much covers it!).
Simply stated, you reset it via a safe connection with another human being, another nervous system. If that connection includes right brain awareness of emotions and body sensations your recovery will be that much faster. For many people this is accomplished in psychotherapy within the therapeutic relationship with their therapist.
1. I like Dr. Scaer's definition of trauma. He suggest that an event is "traumatic" when it overwhelms the capactiy of the nervous system to handle. In other words, facing trauma is something we humans cannot avoid as we move through life.

Stephen Porges' identified two, not one, branch of the parasympathetic nervous system. His discovery of the dorsal vagal (and its relationship to the ventral vagal) has helped us to understand the freeze response and its relationship to voodoo death and PTSD. The polyvagal theory has also been useful in understanding the mind body connection. You can access his classic 1995 article here (you will be taken off site:
