What is Brain Fog and How to Treat it?

What is Brain Fog?

Brain fog is an ambiguous set of symptoms that indicate lagging brain function, such as:

• Forgetfulness
• Lack of focus or trouble concentrating
• Inability to think clearly
• Mental fatigue
• Losing your train of thought mid-sentence
• Forgetting words

These could be signs of aging or fatigue, but they are neither normal nor healthy. Otherwise, the chances are that you are probably experiencing brain fog.  Brain fog means your brain cells struggle to produce enough energy to function optimally.

Brain fog is not a medical condition, but it can be a clinical manifestation of some medical conditions related to poor brain energy production. This may include:

• Mental health issues
• Poor cognition and concentration
• Forgetfulness
• Having excess body fat
• Constant tiredness, etc.

Therefore, if you struggle with brain fog, you should see a doctor to rule out potentially severe issues and get the appropriate treatments. Now, once these are ruled out, let’s look at the lifestyle causes of brain fog and how to fix it naturally.

What Causes Brain Fog?

Your brain requires a lot of energy to function properly. It weighs 2% of your body weight but uses 60-70% glucose. Each of your brain cells produce energy with the mitochondria, the cell’s energy powerhouse. 

Any factor that prevents optimal energy production in the brain can contribute to brain fog. These may include:

• High oxidative stress (stress to the body caused by the accumulation of free radicals) or inflammation
• Lack of brain blood flow or oxygen delivery
• Nutrient deficiencies

Therefore, the following factors can contribute to brain fog:

Poor Mitochondria Health

The mitochondria are the energy powerhouse of the cell. The energy produced by the mitochondria is important for:

• Neuronal signal transmissions
• Neurotransmitter production and transport
• Enhancing the plasticity (the ability of nerve cells to recognize their connections)
• Pumping the nutrients into brain cells

• Supporting the gut-brain axis
• Producing energy required for the detoxification of toxins produced by bacteria in the gut which keeps the toxins from affecting brain function

Therefore, poor mitochondrial health can cause brain fog.

Low oxygen or blood flow to the brain

You need to breathe oxygen to stay alive because oxygen is necessary to accept electrons during the last step of mitochondrial energy production. When your brain lacks oxygen, it accumulates extra electrons, generating more oxidative stress that further interferes with energy production.

The lack of oxygen can inhibit mitochondria function if you have anemia or low brain blood flow. High or low blood pressure can also reduce blood flow to the brain, which may contribute to age-related brain atrophy (shrinkage). 

Declining Mitochondria Function Associated with Aging

Aging can contribute to brain fog because of the following cellular changes:

• Reducing mitochondria function, resulting in cellular energy loss
• Poor stress response
• Accumulating DNA damages
• Cell suicide (apoptosis) of neurons
• Increased inflammation

Poor Gut Health

Your gut and gut microbes play important roles in your brain and mental health. Modern science is trying to fully understand how. But we now know that the gut-brain-microbiota axis includes:

• The gut, brain, and the gut microbes
• The millions of neurons between your gut and brain
• The physical and chemical connection between the three

Microbes in our gut can modulate the brain-gut axis via various mechanisms, including changes in microbial composition or the production of neurotransmitters. This means that chemicals produced by your gut also affect your brain.

Since serotonin is a “happiness hormone,” you may expect the brain to be the center of its production. But your gut is the source of over 90% of your serotonin. Also, your gut bacteria regulate the production of serotonin by gut cells. Low serotonin levels have been linked to mood disorders and memory problems, which are also brain fog symptoms.

Certain bacteria in the digestive tract can produce metabolites that harm the brain’s mitochondria function. For example, inflammation and some gut bacteria can convert tryptophan into quinolinic acid, which is neurotoxic. Quinolinic acid may contribute to brain fog, mental health, and neurologic disorders.

Unhealthy Diet

You are what you eat. The clarity of our thoughts and ability to focus are all directly correlated with our diet. Therefore, an unbalanced and unhealthy diet is among the possible causes of brain fog.

Unhealthy foods are low in micronutrients that are important for mitochondria function. Also, they can cause inflammation and increase oxidative stress, further inhibiting brain energy production. These foods include:

• Sugar and high-fructose corn syrup
• Artificial trans fats
• Vegetable and seed oils
• Refined carbohydrates
• Excessive alcohol
• Processed meat

Some people find that their brain fog improves once they stop eating these foods. Mainly unhealthy diets can cause leaky gut and metabolic endotoxemia.

Leaky Gut (Intestinal Permeability)

Brain fog may also signal a leaky gut, also known as increased intestinal permeability. When you have a leaky gut, microbes and food can be exposed to the immune system, causing inflammation. 

Causes of leaky gut include:

• Unhealthy stress response
• Unhealthy gut bacteria
• An unhealthy diet high in saturated fats and inflammatory foods
• Gut health issues
• Traumas, health defects, surgeries

Symptoms of the leaky gut may include:

• Bloating
• Digestive irregularities
• Food sensitivity
• Fatigue and brain fog
• Mood swings

A leaky gut, especially from high-fat or sugary meals, can also cause metabolic endotoxemia. This is when a toxic component of Gram-negative bacteria cell walls, lipopolysaccharides (LPS), leaks into your bloodstream and causes chronic inflammation. Metabolic endotoxemia can contribute to insulin resistance, weight gain, brain fog, fatigue, and other health issues.

Endotoxemia increases many inflammatory signals in the body, such as interleukins and tumor necrosis factors. The inflammation increases oxidative stress, which reduces brain mitochondria function. Endotoxemia also changes how cells use oxygen, increasing the production of oxidative agents and decreasing mitochondrial function.

Nutrient Deficiencies

Nutrient deficiencies can cause brain fog because your cells need nutrients to produce energy effectively. 

If you can’t get enough of these nutrients, consider supplementing. Many people benefit from temporary high doses of these nutrients if their brain fog is caused by low vitamins, minerals, and other nutrients. Here, we discuss some nutrients most commonly associated with brain fog symptoms.

Omega-3 Fatty Acids

Omega-3 fatty acids have many health benefits. They make us smarter because they provide energy and make up the membranes of our neurons. Moreover, they influence the flexibility of membranes, which contributes to better mitochondria signaling.

Also, omega-3 has anti-inflammatory properties and reduces discomfort. It makes us leaner by improving insulin sensitivity and helping our bodies use stored body fat for energy.  Here, we focus on its role in improving brain health and brain fog symptoms such as difficulty with attention and memory.

Many studies support findings that omega-3 fatty acids limit neuroinflammation by reducing cytokines and increasing lipid mediators responsible for the resolution of inflammation. 

Daily supplementation of 1.25 or 2.5 grams of omega-3 fatty acids reduces memory decline in people experiencing loneliness. It also may improve symptoms of mental health challenges and boost mood if taken daily in a concentration of at least 1 gram.

Furthermore, it also helps with mental unease. People with this issue may also experience brain fog symptoms as it affects mood, memory, and the ability to focus.

B Vitamins

Vitamins from the B complex usually involve eight vitamins: 

• B1 (thiamin)
• B2 (riboflavin)
• B3 (niacin)
• B5 (pantothenic acid)
• B6 (pyridoxine)
• B7 (biotin)
• B9 (folate)
• B12 (folic acid).  

Low B12 may worsen brain fog symptoms related to memory and concentration. 

But remember that these B vitamins work together in your mitochondria and brain. So, it is usually better to consume B complex than B12 alone if you want to address brain fog symptoms.

Scientists examined the effect of vitamin B12 supplementation on vitamin B12-deficient patients with noted symptoms of minimal cognitive impairment. 

A total of 202  patients underwent vitamin B12 replacement therapy. Out of them, 84% (171) reduced their cognitive impairment symptoms, and 78% (158) improved scores on memory and attention after B12 supplementation. 

Low or deficient levels of B12 and B6 are associated with poor memory and concentration and may worsen brain fog symptoms.

Vitamin D

Vitamin D is an essential fat-soluble steroid hormone from sun exposure and food. It is necessary for the proper function of the immune, hormonal, and nervous systems. Therefore, low vitamin D levels may negatively affect cognitive functions and give rise to brain fog.

Therefore, vitamin D supplementation may help alleviate brain fog and improve mental health and mood.

Magnesium

Magnesium is essential for various body functions, including energy production, nerve function, metabolism, and promoting blood pressure regulation.

75% of Americans do not consume even the recommended daily magnesium intake. This can contribute to brain fog symptoms like poor concentration. They may also be more susceptible to unhealthy stress responses due to low magnesium. This can further contribute to mental unease and poor memory.

In a study including 2,466 60-year-old patients, those with higher magnesium intake levels had better performances on cognitive tests and lower risks of developing cognitive impairments than those with low magnesium levels.

Poor Sleep

Poor sleep increases unhealthy inflammatory and stress responses, which reduces mitochondria function. This can also damage the mitochondria and neurons.

Adequate and high-quality sleep is vital for the brain’s normal function, especially during early developmental stages. Sleep disturbances and deficits during early life may have detrimental consequences. They could be linked with later-life cognitive and behavioral impairments.

Also, sleep deprivation disrupts our brain cells’ ability to communicate, which leads to temporary mental lapses and affects memory and visual perception.

If you often wake up tired and brain fogged, consider asking your doctor for a sleep study to rule out sleep disorders.

Stress and Traumas

Stress is the number one cause of brain fog and other mental and clinical conditions. It weakens your immune system, increases blood pressure, causes mental fatigue, and makes you feel exhausted and unable to focus or think. If you experience this type of fatigue, the best solution is to get some rest, as well as try healthy, effective supplements, such as mood supplements, to help promote healthy stress response.

Oxidative stress affects mitochondria function and structure. Mitochondrial failure is considered a crucial factor in mental disorders’ pathogenesis. 

Scientists evaluated the effects of exposure to stress on mitochondrial function and structure in the mouse brain. They found that stress is associated with symptoms of mental health challenges, reduced mitochondrial respiratory rates, and damaged mitochondrial microstructures in the brain.

Stress also affects mitochondrial function in the brain by altering cortisol levels. Impaired mitochondrial function in brain cells reduces cellular resilience and plasticity and impairs the function of synapses.

Stress and trauma increase cortisol which can also increase blood sugar levels and suppress the immune system. However, long-term exposure to cortisol may damage nerve cells in the hippocampus (the brain’s memory center). 

The hippocampus is a significant component of the human brain that enables the consolidation of information from short-term to long-term memory. Therefore, its impairment can cause learning difficulties and forgetfulness. Sustained stress may lead to high levels of cortisol circulating in the body, which can affect mood.

Medication and Recreational Drug Use

Suppose you are experiencing symptoms of brain fog while consuming medications or drugs. In that case, you should immediately consult your physician or pharmacist to replace a drug or lower the existing dosage, as it may be a side-effect of medication, such as:

• Antianxiety drugs (Benzodiazepines)
• Cholesterol-lowering drugs (Statins)
• Antiseizure drugs
• Parkinson’s drugs
• Antidepressant drugs
• Narcotic painkillers
• Hypertension drugs (Beta-blockers)
• Antihistamines
• Incontinence drugs (Anticholinergics)
• Sleeping aids

Researchers found that chronic alcohol consumption is linked to a decrease in the brain’s grey matter, consisting of nerve cells and connections between neurons. Also, it is connected with a decline in the brain’s white matter integrity, consisting of long nerve fibers that collect information through the nervous system. 

Marijuana use is also linked to brain fog symptoms. It is related to declines in the integrity of white matter. It also affects the quality of connections between brain cells, especially those who started consuming it at a young age.

If you aim to maximize your brain function and fix brain fog, you should avoid alcohol and marijuana. Scientists are still working to understand which is worse and their combined effects when you use both. But we know that they both can cause brain fog.
