How Long Does Brain Fog Last After Covid

How Long Does It Last

Battling brain fog after COVID-19

The duration of brain fog varies. For some people, symptoms might fade shortly after recovering from COVID-19. For others, they can continue for far longer.

Brain fog is often associated with long COVID syndrome. Studies suggest its effects can last for weeks or even months after recovering from COVID-19.

A 2021 study found that the length of long COVID-related brain fog might depend on the severity of a persons COVID-19 symptoms. Mild cases saw brain fog symptoms lasting around 2 weeks after recovery, while more critical cases saw symptoms beyond 6 weeks.

What Are Some Possible Lingering Mental Health Effects Of Covid

One of the most common mental health effects and challenges has been depression and anxiety, said Dr. Sanghavi. The pandemic itself has brought about a lot of challenges to the patients life, be it financial or personal, and add to it the recuperation from an illness like COVID.

The other symptoms you would notice is brain fog, which is akin to cognitive impairment that you see in patients who have post intensive care unit syndrome, he added, noting that other mental health effects might be insomnia and PTSD.

Where To Get Treatment For Brain Fog

Many hospitals have cognitive rehab programs, even if theyre not specifically geared to long COVID patients. Treatment for brain fog is also available at many long COVID clinics. These centers, which are cropping up at an increasing number of hospitals, include Mount Sinai Center for Post-COVID Care in New York City, UT Health Austin Post-COVID-19 Program in Austin, Texas, and Memorial Primary Care Long Haulers Clinic in Hollywood, Florida. You can find a list on the website of the patient support group Survivor Corps.

Cog rehab generally requires one to several sessions a week for a couple of months or more. Treatment for brain trauma and stroke is typically covered by insurance but whether insurers will foot the bill for post-COVID complications is an open question.

There is some evidence that playing games like CogMed, Lumosity, and Brain HQ on your computer or phone may also improve cognition. These can be a great supplement to working with a cognitive rehabilitation therapist or coach, Wethe says.

      Dealing With ‘brain Fog’ From Long Covid


      Long COVID-19, also known as post-COVID syndrome, involves a wide range of health problems that occur many weeks, months and years after recovering from COVID-19 infection. Sometimes, symptoms of long COVID-19 can include cognitive difficulties.

      “Brain fog” has been used to describe some of these symptoms. While “brain fog” is not a medical condition, it’s a term used for certain symptoms that can affect one’s ability to think.

      Billie Schultz, M.D., a Mayo Clinic physical medicine and rehabilitation expert, discusses what can be done to help patients experiencing “brain fog.”

      Short-term memory loss, confusion and difficulty concentrating are all things those suffering from “brain fog” may experience after recovering from COVID-19 infection.

      “‘Brain fog’ is just kind of this feeling that you’re trying to do something, and it’s taking more effort. It’s harder to do. You don’t feel like you’re picking up all of those details almost as if you’re driving through a fog,” says Dr. Schultz.

      While there’s no one-size-fits-all treatment that can cure these cognitive difficulties, some rehabilitation strategies can retrain the brain to work on the areas that are most challenging.

      “Typically, it means going into work with a therapist initially once or twice over the course of a month. And getting homework. ‘I want you to try to utilize these strategies in your day-to-day life.’ Because, ultimately, that’s what decides if they’re working.”

      What Is Astounding Is The Scale

      “Normally people of this age don’t have this type of impairment. Maybe in the single-digit proportion,” Lavretsky says. “This is not unlike other viral diseases like HIV, for instance or Lyme Disease. What is astounding is the scale â so many have it.”

      She says that because so many people have been infected with COVID-19 the numbers with these effects translate to hundreds of thousands, which will come with great cost to the health care system and work productivity losses.

      “Disability will break the bank,” Lavretsky said. “Within the next year, we will all realize how tremendous this problem is.”

      Tracy Vannorsdall, PhD, associate professor of psychiatry and behavioral sciences, at Johns Hopkins Medicine, in Baltimore, says she is also seeing similar effects after COVID illness.

      This study shows that the lasting effects are found at all levels of illness from COVID-19, Vannorsdall says, adding that the findings also add concern to what happens to young COVID survivors as they age.

      Vannorsdall said the findings of this study suggest clinicians should be asking more questions about cognitive function and memory.

      Brain Fog Other Long Covid Symptoms Can Last More Than A Year Study Finds

      The devastating neurological effects of long Covid can persist for more than a year, research published Tuesday finds even as other symptoms abate.

      The study, published in the journal Annals of Clinical and Translational Neurology, is the longest follow-up study of the neurological symptoms among long Covid patients who were never hospitalized for Covid.

      The neurological symptoms which include brain fog, numbness, tingling, headache, dizziness, blurred vision, tinnitus and fatigue are the most frequently reported for the illness.

      The new study, from researchers at Northwestern University, is a follow-up to a shorter-term study published last spring that focused on 100 patients with long Covid. That research found that 85 percent of the patients reported at least four lasting neurological problems at least six weeks after their acute infections.

      For the follow-up, the team continued to survey 52 of the original participants, who were patients at the universitys Neuro COVID-19 Clinic a long Covid clinic for up to 18 months. The cohort was three-quarters female, and the average age was 43. Almost 80 percent were vaccinated, and all had mild Covid symptoms that did not require hospitalization.

      There are several conditions that can produce brain fog. For example, during and after pregnancy some people report having pregnancy brain or mommy brain” and people with cancer undergoing chemotherapy often describe experiencing chemo brain. Other medical conditions that are known to cause mental fogginess are multiple sclerosis, traumatic brain injuries, and chronic fatigue syndrome. The symptoms can also be caused by certain medications.

      “In some people, it can be that the virus directly attacks the brain, Budson said. That’s not common, but it can happen. He adds that the virus can also cause strokes which can affect cognitive function.

      Jackson explained that people who were severely ill with COVID-19 could have experienced small areas of brain damage from hypoxia and inflammation while they were on ventilators.

      Links With Genetic Dementia Risk

      What is COVID-19 âbrain fogâ? and why should we be concerned?

      Dementia is a risk factor for severe COVID-19, increasing the chances of being hospitalized more than three times. Another study from the U.K. Biobank has shown a link between the ApoE e4 genotype, associated with Alzheimers disease and severe COVID-19.

      A paper presented at the Alzheimers Association International Conference 2021 by Prof. M. Wisniewski showed that hospitalized patients with COVID-19 and neurological symptoms were more likely to have serum biomarkers of neuronal injury, neuroinflammation, and Alzheimers disease, indicating an acceleration of Alzheimers pathology.

      Moreover, a study whose results appeared in Brain in October 2021 found a further link between the genetic risk for dementia and the risk of developing severe COVID-19.

      Namely, a specific variant of the OAS1 gene which influences the risk of Alzheimers disease is also tied to an increased risk of severe COVID-19.

      According to the study authors, this is because a lowered expression of OAS1 in microglia, a type of neural cells found in the brain and spinal cord, is associated with a heightened pro-inflammatory response at cellular level.

      In a comment for Science Media Centre, Dr. David Strain, Senior Clinical Lecturer at the University of Exeter in the U.K., notes that his is robust research that supports some of the early observations that people with Alzheimers disease were at an increased risk of poor outcomes from COVID-19.

      Over-Stimulated Immune System May Be Impetus to Cognitive Symptoms, UCSF-Led Study Shows

        Some patients who develop new cognitive symptoms after a mild bout of COVID-19 have abnormalities in their cerebrospinal fluid similar to those found in people with other infectious diseases. The finding may provide insights into how SARS-CoV-2 impacts the brain.

        In a small study with 32 adults, comprising 22 with cognitive symptoms and 10 control participants without, researchers from UC San Francisco and Weill Cornell Medicine, New York, analyzed the cerebrospinal fluid of 17 of the participants who consented to lumbar puncture. All participants had had COVID-19 but had not required hospitalization.

        They found that 10 of 13 participants with cognitive symptoms had anomalies in their cerebrospinal fluid. But all four of the cerebrospinal samples from participants with no post-COVID cognitive symptoms were normal. The research publishes on Jan. 18, 2022 in Annals of Clinical and Translational Neurology.

        The average age of the participants with cognitive symptoms was 48, versus 39 for the control group. Participants with these symptoms presented with executive functioning issues, said senior author Joanna Hellmuth, MD, MHS, of the UCSF Memory and Aging Center. They manifest as problems remembering recent events, coming up with names or words, staying focused, and issues with holding onto and manipulating information, as well as slowed processing speed, she said.

        How Long Does Brain Fog Last

        Brain fog typically doesnt persist indefinitely but instead comes and goes . When it strikes, it can stick around for just a few hours. Unfortunately, it can also linger for months. Both are extreme, though.

        The duration of brain fog varies from person to person. In general, brain fog lingers between several days and several weeks.

        You can do things to reduce the duration of brain fog. How long brain fog lasts depends largely on things that are under your control. This means, of course, that you can reduce the symptoms of brain fog and shorten their duration. Lets look at how to clear brain fog quickly.

        How Do You Clear Brain Fog Quickly

        You can clear brain fog. The fact that it lasts from hours to months and everything in-between, means that its not permanent brain damage. You can indeed do things to clear your brain fog. You can even unblock your brain fairly quickly by taking the right actions.

        One caveat to solutions for how to clear brain fog quickly: there isnt a magic wand or special elixir that will blow away the fog instantaneously. The steps you can take are actions that reduce the symptoms by working to help the brain heal itself and return to proper functioning. Clearing brain fog doesnt have to take months, but it takes more than a couple of hours.

        The overarching theme in how to clear brain fog quickly is self-care. Lifestyle has a big impact on brain health. Intentionally doing a thing that nurtures your brain will help brain fog go away and stay away. Important components for self-care for brain health include such things as:

        How Does Long Covid Brain Fog Impact A Persons Life

        An online survey of one thousand adults looked at cognitive impairment and quality of life associated with long COVID. The survey included people who had been infected with COVID-19, people with long COVID, and for comparison, people who had neither. The results clearly showed the impact of long COVID on quality of life.

        • Those with COVID, particularly long COVID, had higher rates of cognitive dysfunction.

        • Those with long COVID had greater challenges with work and household responsibilities. They also had higher rates of unemployment and less financial security.

        What Is Brain Fog

        ‘Brain fog’ can be a long-term effect of COVID-19

        Brain fog, a term used to describe slow or sluggish thinking, can occur under many different circumstances for example, when someone is sleep-deprived or feeling unwell, or due to side effects from medicines that cause drowsiness. Brain fog can also occur following chemotherapy or a concussion.

        In many cases, brain fog is temporary and gets better on its own. However, we don’t really understand why brain fog happens after COVID-19, or how long these symptoms are likely to last. But we do know that this form of brain fog can affect different aspects of cognition.

        Testing May Fall Short In Diagnosing Mild Cognitive Disorders

        All participants underwent an in-person cognitive testing battery with a neuropsychologist, applying equivalent criteria used for HIV-associated neurocognitive disorder . Surprisingly, the researchers found that 13 of the 22 participants with cognitive symptoms met HAND criteria, compared with seven of the 10 control participants . Comparing cognitive performance to normative references may not identify true changes, particularly in those with a high pre-COVID baseline, who may have experienced a notable drop but still fall within normal limits, said Hellmuth.

        If people tell us they have new thinking and memory issues, I think we should believe them rather than require that they meet certain severity criteria.

        Cognitive symptoms have been identified in other viruses, in addition to COVID-19 and HIV. These include the coronaviruses SARS and MERS, hepatitis C and Epstein-Barr virus.

        If I Lost My Smell Or Sense Of Taste Will I Get It Back

        According to one study, 95% of the patients recover their sense of taste and smell eventually, said Dr. Sanghavi, adding that it may take months, but their sense of taste and smell sensation would come back.Initially it was thought that it is a direct invasion of virus into the olfactory cells or the neurons, but now, as we understand the process more, it seems like this impacts the helper cells and not the neurons directly, he said. And as the helper cells recover, the sense of taste and smell recover too.

        People may ask if they can do anything to get it back and re-sensitization with aromatherapy is one way that could potentially work, but there is no clear proof that anything works right now, said Dr. Sanghavi.
