Yes, long COVID can significantly affect the brain, causing issues like brain fog, memory problems, inflammation, reduced brain volume, and even accelerated brain aging, with research showing lasting changes in brain structure and function after both mild and severe infections. These neurological impacts can include cognitive deficits, prolonged brain inflammation, and cellular changes like brain cell fusion, impacting electrical activity and function.
What are the most common symptoms of long COVID?
Perception and sensation symptoms of TBI
It usually goes away completely between six and nine months after the infection, although in some people it lasts as long as 18 months or more, Dr. McAlpine says. Scientists don't yet have a solid understanding of what causes Long COVID brain fog.
COVID-19 lasts anywhere from a few days to a few weeks. Once symptoms (if you have them) clear up, it usually means that COVID-19 isn't in your body anymore. Some people may develop long COVID — a wide range of symptoms that last weeks, months, or years after COVID-19 illness.
A study found that, although patients were still experiencing some cognitive difficulties six months after their infection, there was a marked improvement in neurological and cognitive function since the illness. All that said, we've found that many symptoms of long COVID are reversible with treatment.
The 12 Most Common Long COVID Symptoms
Vitamin B2 and vitamin B7 help the nervous system, vitamin B3 and vitamin B6 are required to support neurotransmitters and cellular communication, and vitamin B9 eases mental fatigue. Taking a regular B complex supplement that includes all the necessary B vitamins can help to reduce symptoms of brain fog.
Brain fog can be a symptom of a nutrient deficiency, sleep disorder, bacterial overgrowth from overconsumption of sugar, depression, or even hormone dysfunction, such as a thyroid condition or perimenopause.
Long-COVID patients with neuropsychiatric symptoms such as brain fog showed abnormal brain activity on magnetic resonance imaging (MRI) while completing memory tests, with a shift from activity in brain areas normally used for memory to other brain regions, shows a study published yesterday in Neurology.
Five significant signs your brain might be in trouble include memory loss (especially recent events), difficulty with familiar tasks or language, confusion about time/place, significant personality/behavior changes, and problems with judgment, focus, or coordinating movement, often indicating conditions like dementia, brain injury, or other neurological issues, requiring a doctor's visit.
Moderate to severe traumatic brain injuries
Loss of consciousness from several minutes to hours. Persistent headache or headache that worsens. Repeated vomiting or nausea. Convulsions or seizures.
Stage 1 (No response)
The child or young person appears to be in a deep sleep and doesn't respond to sounds or stimulation. This is referred to as 'coma'. While in coma, the brain is not functioning at the normal level. There is a limited ability to take in information or respond to light, sound or touch.
Researchers in Japan have pinpointed a biological cause of Long COVID brain fog using advanced PET brain imaging. They discovered widespread increases in AMPA receptor density linked to cognitive impairment and inflammation.
Other symptoms can include:
By some estimates, 400 million people worldwide have been diagnosed with some form of long Covid. But an infection can also lead to other issues, including lung and heart damage and microbiome changes in the gut, that may not always be recognized as long Covid but can still have a lasting effect on our health.
Common symptoms of neurological disorders include:
This results in poor oxygen flow to your body's organs and tissues, leading to brain fog-related symptoms like weakness and fatigue, along with much more serious neurological problems. Even if you don't develop anemia, B12 deficiency can cause confusion, memory troubles and depression.

Conclusion: A Clear Mind Starts with the Right Minerals
Brain fog doesn't have to define your days. With magnesium, you may have the key to mental clarity you've been seeking. From improving neurotransmitter function to reducing the effects of stress, this mineral is a powerhouse for brain health.
Vitamin D supplements are linked to a significant reduction in dementia risk, with a major study showing users had a 40% lower incidence of developing dementia compared to non-users, particularly benefiting older adults, with even greater effects seen in women and those without existing cognitive issues. This reduction highlights Vitamin D's role in brain health, possibly by clearing amyloid plaques associated with Alzheimer's.
B vitamins like B6, B12 and B9 (folic acid) are crucial for brain health and may help prevent cognitive decline and improve memory in older people.
What are some of the unusual symptoms of COVID-19?
Complications of severe COVID-19 illness can include:
Fatigue, brain fog, and post-exertional malaise (PEM) are commonly reported symptoms, but more than 200 Long COVID symptoms have been identified.
