Omicron and Brain Fog

Many who have contracted the coronavirus have reported experiencing a loss of cognitive function or brain fog. This refers to a variety of cognitive difficulties, including slower mental processing, memory loss, and feelings of confusion and disorientation.

How long does long COVID brain fog last?

In August 2022, a study published in the Lancet Psychiatric Journal looked at over a million patients diagnosed with the coronavirus. It found that those patients had an increased risk of developing cognitive issues such as brain fog even after 2 years.

While some people recover from coronavirus relatively quickly, others may experience longer-lasting effects. Some patients with mild cases of the virus are reporting experiencing long COVID symptoms.

According to the CDC, almost 15% of patients who have recovered from coronavirus reported experiencing brain fog.

The CDC notes that these groups of people have a higher risk of experiencing brain fog:

  • Patients who were hospitalized for severe COVID-19.
  • Those who have underlying health conditions.
  • Those who were not vaccinated for COVID-19.
  • Patients who experienced multisystem inflammatory syndrome (MIS) during or after COVID-19 illness.

What are the symptoms of long COVID brain fog?

  • Memory loss
  • Decreased attention span
  • Unable to focus for extended periods of time
  • Unable to multitask

These symptoms can affect a patient’s ability to complete simple tasks such as paying bills, comprehending written materials, and remembering to take medications.

Key Takeaway: Brain fog is a common condition that can be caused by sleep deprivation, stress, and nutritional deficiencies. There is no cure, but some natural remedies may help improve symptoms.

When Should You See a Doctor?

If you are experiencing symptoms of brain fog after contracting COVID, you should consult your doctor. 

Depending on your symptoms, a neuropsychologist may recommend a cognitive test to determine the extent of your cognitive impairment. This in-depth examination will measure your cognitive abilities, behavior, and any personality/mood disorders.

Your doctor may recommend that you undergo cognitive therapy during your rehabilitation. The post-COVID program at JFK JCI at Hackensack-Meridian health offers a comprehensive evaluation and develops a targeted treatment plan to help you recover.

How to Overcome Brain Fog

While brain fog can be frustrating, there are ways to treat it.

  • Improve your sleep quality.
  • Eat a healthy, Mediterranean-style diet.
  • Participate in light to moderate exercise as tolerated, but avoid activities that cause you more fatigue later or over the next few days.
  • Stay away from alcohol or medication that will impact your cognitive functioning.
  • Prioritize your mental health.

One way to treat brain fog is to make sure you’re getting enough sleep. This can be difficult if you have a busy lifestyle, but it’s important to get at least 7-8 hours of sleep each night. You can also try taking a nap during the day if you’re feeling particularly fatigued.

Another way to treat brain fog is to eat a healthy diet. Eating plenty of fruits, vegetables, and whole grains can help improve your cognitive function.

Additionally, drinking plenty of water and avoiding sugary drinks can also help.

If you’re still struggling with brain fog, there are several supplements that can help. Omega-3 fatty acids, ginkgo biloba, and B-complex vitamins are all great options. You can talk to your doctor about which supplements are right for you.

The coronavirus is a very serious condition, and the best way to prevent long COVID and brain fog is to get vaccinated and strictly follow the CDC’s guidelines for wearing masks and practicing social distancing.

Key Takeaway: Brain fog can be treated by getting enough sleep, eating a healthy diet, and taking supplements.
