As a cognitive behavioral neurologist, I’ve been hearing from many individuals who are complaining of “brain fog” after infection with COVID-19. So I thought it was worth discussing exactly what COVID-19 brain fog is, and some things to do that might help clear it.
What is brain fog?
Let’s start by trying to understand brain fog. Brain fog is not a medical or scientific term; it is used by individuals to describe how they feel when their thinking is sluggish, fuzzy, and not sharp.
We all experience this feeling from time to time. Perhaps you couldn’t think clearly when you were sick with the flu or another illness. Maybe you were jet-lagged and your thinking was sluggish because it felt like it was 2 AM. Or perhaps you took an antihistamine or another medication that made your thinking fuzzy for a few hours. In each case you probably just waited to get back to normal, whether that meant recovering from your illness, adjusting to the new time zone, or waiting for the side effects of the medication to wear off.
But what if your thinking didn’t return to normal?
What is COVID-19 brain fog?
How COVID-19 affects the brain
There are many ways that COVID-19 can damage the brain. As I described in a previous blog post, some can be devastating, such as encephalitis, strokes, and lack of oxygen to the brain. But other effects may be more subtle, such as the persistent impairment in sustained attention noted by Chinese researchers.

In addition to direct effects on the brain, COVID-19 can also have long-term effects on other organ systems. So-called long haulers can have other lingering symptoms including fatigue, body aches, inability to exercise, headache, and difficulty sleeping. Some of these problems may be due to permanent damage to their lungs, heart, kidneys, or other organs. Damage to these organs — or even just the symptoms by themselves — can impair thinking and memory and cause brain fog. For example, how can you think clearly if you’re feeling fatigued and your body is aching? How can you concentrate if you were up half the night and awoke with a headache?

What should you do if you may be experiencing COVID-19 brain fog?
The first and most important thing to do is to see your doctor and share with them all of the lingering symptoms you are experiencing. These should include your brain fog and other neurologic symptoms (such as weakness, numbness, tingling, loss of smell or taste), and also problems such as shortness of breath, palpitations, and abnormal urine or stool.
What might help clear the brain fog?
To help clear the brain fog, I recommend pursuing all of the activities that we know help everyone’s thinking and memory.
Perform aerobic exercise. You may need to start slow, perhaps just two to three minutes a few times a day. While there is no established “dose” of exercise to improve brain health, it’s generally recommended you work toward 30 minutes a day, five days a week.

Eat Mediterranean-style meals. A healthy diet including olive oil, fruits and vegetables, nuts and beans, and whole grains has been proven to improve thinking, memory. and brain health.

Avoid alcohol and drugs. Give your brain the best chance to heal by avoiding substances which can adversely affect it.

Sleep well. Sleep is a time when the brain and body can clear out toxins and work toward healing. Make sure you give your body the sleep it needs.

Participate in social activities. We are social animals. Not only do social activities benefit our moods, but they help our thinking and memory as well.

Pursue other beneficial activities, including engaging in novel, cognitively stimulating activities; listening to music; practicing mindfulness; and keeping a positive mental attitude.

Advancements for Improving Health Outcomes
Quality and Safety in Clinical Operations is a Harvard Medical School course being held in a live virtual format from June 8-10, 2022. This Continuing Education course will focus on ways to identify gaps and develop successful, sustainable, scalable interventions that lead to improved outcomes. You will leave this course with a pathway to review your institution’s current program and identify ways to advance strategically and tactically to impact outcomes. Lessons learned from the COVID-19 will be highlighted, including the need to aggressively advance our institutional approach to equity.
