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.
How COVID-19 affects the brain?
There are many ways that COVID-19 can damage the brain. It can be devastating, as someone can get 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, and 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, we recommend pursuing the following activities:
• 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 such as reading a novel, cognitively stimulating activities; listening to music; practicing mindfulness; and keeping a positive mental attitude.
So, it is of utmost importance to act swiftly on 7 to 10 days by use of anti-inflammatory medications. And most of the current-day medications like corticosteroids, Tocilizumab, convalescent plasma work best when given in time during this phase.
