Panic attacks, explained.
Breaking down panic attacks and understanding their mechanisms
People who have suffered from panic attacks will know what it’s like to experience sheer terror. It is a psychological phenomenon that causes a powerful effect on the body. The DSM-V (the Diagnostic and Statistical Manual of Mental Disorders) indicates that panic attacks are characterized by a range of physical symptoms, such as shortness of breath, chest pain, shaking, and feeling faint. If that weren’t enough, panic attacks are also accompanied by intense emotional experiences, where people will truly believe that they are dying or losing their mind.
If this sounds like a horrendous experience that only strikes the unlucky few — think again. Panic attacks are actually pretty common. Findings from the National Comorbidity Survey Replication suggest that around 1 in 5 US citizens will experience a panic attack in their lifetime. Luckily, research has made incredible strides to understanding the whys, hows, and whens of panic attacks.
Cognitive psychology has presented one of the most comprehensive and evidence-based models of panic (see Clark, 1986), which breaks it down into four distinct components.
- The trigger
Panic attacks are sometimes preceded by clear, identifiable triggers. This trigger does not have to present an actual threat to life (e.g. being held at gunpoint) to elicit a panic attack — being placed in a situation that creates intense fear, such as public speaking, is sufficient.
However, many people will report that their panic attack was out-of-the-blue and completely unexpected. So, what’s happening in these cases? According to psychologists, these “uncued” panic attacks are triggered by much more subtle internal or external stimuli. These might take the form of thoughts (like anxious predictions that something bad will happen), or bodily sensations (like your heart beating faster when you are nervous, or your noticing pain in some part of your body).
2. Activation of fight-flight response
Whatever the trigger, what is crucial is that the brain perceives that it is under threat, which activates the “fight or flight response”. A cascade of hormonal signals are then sent around the body to prepare you to fight, run away as fast as you can, or if all else fails — play dead.

This then instigates a whole host of physiological changes, which might lead to an accelerated heart rate, increased alertness, heavy breathing, and butterflies in the stomach. Each of these responses is unique evolutionary adaptations so that you have the best chance of survival when something dangerous comes your way.
Think of your fight-flight response as your over-protective lioness mother. Any whiff of danger, and she’s ready to take someone’s arm off. Unfortunately, what this means in real terms is that our fight-flight response gets triggered even when we are not actually in any danger. That is a lot to put your body through for a false alarm, but better safe than sorry, right?
3. Misinterpretation of bodily sensations
Another handy adaptation of the fight-flight response is that it is an unconscious process, which allows us to react to threat quickly. This is great in situations where there is real danger, as you definitely would not be able to dodge any punches if you had to spend time thinking about it.
However, when our fight-flight system misfires (false alarm), what happens is that we have all these intense physical reactions, but without any observable explanation for them. Imagine sitting on the subway and out of nowhere, your heart starts racing and you break into a cold sweat. Scary, no?
Without an understanding of what is happening to our bodies and minds, people make what psychologists have termed a catastrophic misinterpretation. They interpret their anxiety symptoms as signs of immediate danger to their life or safety. For example, heart palpitations may be interpreted as “I am having a heart attack”. Racing thoughts? “I am losing my mind”. Dizziness? “I am going to collapse”. This then feeds the fight-flight response further, which leads to bodily and psychological symptoms to intensify. Handy.
4. Safety behaviors
Individuals who have suffered from panic attacks may engage in a range of behaviors that they feel might keep themselves safe. Unfortunately, these sometimes have the unintended effect of creating a feedback loop that maintains the cycle of panic. This means people may not resolve their panic attacks or experience them more frequently.
Consider the example of a person who misinterprets their accelerated heart rate as a sign that they are having a heart attack. They begin to pay more attention to their heartbeat (this is known as selective attention), checking in more frequently, so that they can respond quickly if anything seems unusual. However, this will then mean they start to notice many more subtle irregularities in their heartbeat or even pick up things that aren’t really there — things that wouldn’t have happened if they weren’t monitoring. This could then increase the probability that a panic attack is triggered.
Another common safety behavior is avoidance. If you know that you had your last panic attack in a crowd, why not avoid crowds in the future? Well, what this is teaching the body is that crowds are something to be feared, while removing your opportunity to learn that you can be in a crowd without something bad happening.
It is important to note, that whilst panic attacks are genuinely frightening for those affected, they are one of the mental health difficulties which respond best to treatment. Research shows that panic can be treated effectively with both Cognitive Behavioral Therapy (CBT) and medication. Studies have shown recovery rates of up to 93% with CBT, with similar promising results from medications. If panic is something that you are struggling with, please do remember that help is out there.
