What Anxiety Does to Your Brain and What You Can Do About It Image: Shutterstock
We all deal with anxiety in some form day to day. But anxiety can be a much stronger, more fearsome force for many people — one that never goes away. What is anxiety exactly, and what’s going on in your mind (and your body) when anxiety strikes? How do you cope when it takes hold?
Beyond Blue says that in any one year, around one million Australian adults have depression, and over two million have anxiety. Approximately 45 per cent of people will experience a mental health condition in their lifetime. Many people go undiagnosed.
Anxiety itself is a natural human response that serves a purpose. Our goal shouldn’t be to dismiss it entirely but to make it a healthy, manageable part of our lives. Even if you don’t suffer from an anxiety-related disorder, anxiety is part of our world, the same way stress, sadness and happiness are. The key is understanding how to cope with it in a healthy way.
To help us get there, let’s talk about what exactly is going on in your brain when anxiety strikes, how it impacts us, and then what we can do about it, with the help of some experts. What Anxiety Is, and How It Differs from Stress
Anxiety is a sense of fear and apprehension that puts you on alert. Biologically, it’s designed to put us in a heightened sense of awareness so we’re prepared for potential threats. Unfortunately, when we start to feel excessive anxiety, or we live in a constant state of anxiety, we’re in trouble. Our bodies never turn off our fight or flight response , and we live with the physical and emotional effects of anxiety on a day-to-day basis, even when there’s no reason or cause for them.
On its face, anxiety can look like stress ; but the reality isn’t so simple. Anxiety can arise as a result of stress, but stress can manifest in other ways. Stressors can make a person sad, angry, worried or anxious, while anxiety is specifically that feeling of fear, dread and apprehension we mentioned. You may never even know what’s causing your anxiety, or, in some cases, it can manifest on its own, without any real “trigger” or cause. Stress is often caused by external influences, while anxiety is an internal response. That’s part of what makes anxiety intrinsically different than stress, and also what makes it so difficult to manage. What’s Actually Happening In Your Brain When You Feel Anxious
You know the feeling: That tense sensation in your stomach, the heightened sense of awareness you have about everything going on around you, the slight fear or sense of dread — that’s anxiety. Before your body feels the effects however, your brain is already at work. The US National Institute of Mental Health guide to anxiety disorders also offers this description of the neurological processes at work: Several parts of the brain are key actors in the production of fear and anxiety. Using brain imaging technology and neurochemical techniques, scientists have discovered that the amygdala and the hippocampus play significant roles in most anxiety disorders. The amygdala is an almond-shaped structure deep in the brain that is believed to be a communications hub between the parts of the brain that process incoming sensory signals and the parts that interpret these signals. It can alert the rest of the brain that a threat is present and trigger a fear or anxiety response. The emotional memories stored in the central part of the amygdala may play a role in anxiety disorders involving very distinct fears, such as fears of dogs, spiders or flying. The hippocampus is the part of the brain that encodes threatening events into memories. Studies have shown that the hippocampus appears to be smaller in some people who were victims of child abuse or who served in military combat. Research will determine what causes this reduction in size and what role it plays in the flashbacks, deficits in explicit memory and fragmented memories of the traumatic event that are common in PTSD. The feeling of anxiety is part of your body’s stress response. Your fight or flight response is triggered, and your system is flooded with norepinephrine and cortisol . Both are designed to give you a boost to perception, reflexes and speed in dangerous situations. They increase your heart rate, get more blood to your muscles, get more air into your lungs and get you ready to deal with whatever threat is present. Your body turns its full attention to survival. Ideally, it all shuts down when the threat passes and your body goes back to normal. Where Anxiety Comes from and Where It All Goes Wrong
The effects of stress are well understood, but where does anxiety come from? How do we know that it’s time to be “anxious”, and where is the line between “feeling anxious” and “suffering from anxiety”? We sat down with clinical psychologist Jeffrey DeGroat, PhD, and Roger S. Gil, MAMFT, to find that line.
Dr DeGroat explained that there are a number of psychological theories as to why anxiety exists. There’s the neurological (which we mentioned above), and the psychoanalytical, which describes anxiety as battle between the id, ego and superego. In this battle, he explains that “anxiety serves as a danger signal to an individual’s ego and/or superego that an individual is at an elevated risk to act upon an unacceptable id impulse. In the face of this anxiety, an individual’s ego and/or superego respond by attempting to manage an individual’s id impulses through elevated means.” Essentially, anxiety is a warning sign that you’re about to do something you may not want to. There’s also the cognitive theory, which suggests that anxiety arises when a person’s cognitive distortions , or irrational thought patterns, make them see everything as a physical threat, whether it’s an actual physical danger, an annoying coworker or a police officer […]
