The Surprising Overlap Between Anxiety and Brain Fog
Ever feel like you can’t keep things straight anymore? Like your mind is in a haze and you can’t concentrate, think quickly, or remember to complete important tasks? These are some of the signs of brain fog. You might be worried that it’s the onset of dementia, or you may be aware that certain everyday things are associated with brain fog—like poor sleep, some medications, or hormonal imbalances (hello, pregnancy brain or menopause!). But what you may not realize is that anxiety can also be at the root of brain fog.

How Anxiety Taxes the Brain
Anxiety takes up a lot of your brain’s precious resources. When anxiousness fills the corners of your mind with worrisome thoughts and fears, it’s akin to something researchers call cognitive overload. That’s when your brain is bombarded with too much information to be able to process it all effectively. When stress and anxiety hit, your brain is so busy processing those nervous thoughts that it drops the ball on the other cognitive tasks you need to handle. It makes it hard to concentrate, difficult to pay attention, and gets in the way of memory formation. This leads to feeling spacey, being easily distracted, and being forgetful. And that’s a recipe for brain fog.Brain SPECT Imaging, Anxiety, and Brain Fog
Brain SPECT imaging shows that people with anxiety tend to have a very busy brain with too much activity in areas such as the basal ganglia (the anxiety centers of the brain). Overactivity floods the emotional circuits in the brain diverting resources away from important mental processes. In addition, being plagued by chronic stress causes the hippocampus—a brain region that is critically involved in memory formation—to shrink. In the healthy brain, about 700 new neurons, or nerve cells, are formed each day in the hippocampus. However, when your brain is under attack by a constant flood of stressful thoughts, this process can be disrupted, resulting in fewer new neurons. This is bad news for your memory and can be a major contributor to an inability to recall information. Imaging the brain can be helpful in determining if worrisome symptoms of brain fog are a sign of dementia or related to anxiety, exposure to toxins, or other factors.4 TECHNIQUES TO CALM ANXIETY TO CLEAR THE BRAIN FOG
1. Use hypnosis, guided imagery, or progressive muscle relaxation.
When stress and anxiety get out of control, hypnosis, guided imagery, or progressive muscle relaxation can quickly decrease the stress response. Here are the basic steps of you can do this on your own:- Sit in a comfortable chair and stare at a spot on the wall that is slightly above eye level. Let your eyelids close slowly.
- Breathe deeply. With each inhale, imagine taking in peace and calmness, and with each exhale, blow out all the tension. Notice a calm come over you.
- Squeeze the muscles in your eyelids, closing your eyes as tightly as you can. The let them relax and feel that relaxation travel down your face and body.
- After the tension has left your body, imagine yourself at the top of an escalator and ride down while counting backward from 10. By the time you reach the bottom, you should be experiencing a sensation of relaxation.
- Enjoy the tranquility for several moments, then ride the escalator back up counting from 1 to 10. When you reach the number 10, open your eyes, and enjoy feeling refreshed and alert.
