Sudden Lack of Mental Clarity?

Do you often feel?

  • disoriented
  • forgetful
  • unable to concentrate
  • Trouble staying focused?

If so, you are probably wondering, “What is the matter?” Or, you may be asking yourself, “Why am I struggling to do things that used to be simple?” The answer to your questions may lie in a condition colloquially called “brain fog”.

Keep reading to learn more about brain fog as a cognitive dysfunction. We’ll describe common medical causes that contribute to its formation and their characteristics. Finally, we’ll cover how specific nutraceutical can help you eliminate brain fog and get back to feeling like yourself again!  

Read on for more on the main medical causes of brain fog. We invite your questions in the comments section at the end. In fact, we try to respond to all questions personally and promptly. 

What Exactly Is Brain Fog?

According to recent medical studies, brain fog has been described as a widespread cognitive disorder that is similar to mental fatigue. There are many associations connected with brain fog. Yet, the term “brain fog” is imprecise. People describe the condition with words such as: forgetful, cloudy, difficulty focusing, thinking and communicating. Medically speaking,

Brain fog causes an inability to perform usual cognitive tasks. This mental health problem stops you from being able to think clearly.

More specifically, brain fog is a constellation of symptoms that include reduced cognition, inability to concentrate and multitask, as well as loss of short and long term memory. If the symptoms listed above sound familiar, you’re not alone In fact, brain fog is one of the most common cognitive issues people face nowadays. But take hope! There is a way to get out of a state of confusion and start to put your thinking processes back in order.

Brain Fog Symptoms

The ways that people describe “brain fog” have forced the medical community to recognize the symptoms as a cognitive complaint. However, doctors tend to categorize the condition as a perceived experience. Still, the condition can be diagnosed as a cluster of symptoms that occur during episodes or specific time periods. In general, the presence of brain fog is marked by the following symptoms:

The Main Cause of Brain Fog: Toxicity

While brain fog remains a fairly murky and imprecise medical term, most of us can agree that it does not occur as a result of balance. Something has to be out of balance in the entire system that causes brain fog. More specifically, we can think of brain fog as a manifestation of central nervous system (CNS) toxicity. So, what does it mean to have a toxic nervous system?

Toxicity is generally defined as the presence of a chemical substance or a particular mixture of substances that damage cells, tissues, or organs.

In cases of brain fog, something is chemically out of balance in the nervous system. While brain fog can have roots in medical causes (Fibromyalgia, Lupus, auto-immune disease, hormonal change, or Chronic Fatigue Syndrome), not all people who experience brain fog can be diagnosed with medical problems.

At The Mind & Body Institute, we have found that the toxic imbalance that causes brain fog is directly related to:

  1. What we eat.
  2. How we digest.
  3. The health of our digestive system.

The Brain-Gut Connection

How are the brain and the digestive system connected? Our gut microbiome impacts the chemical balance in the brain in numerous ways. Structural bacterial components provide stimulation of the immune system. This means that when bad bacteria is present in our gut, it causes central nervous system inflammation.

  • anxiety
  • concentration troubles
  • confusion
  • decreased motivation
  • difficulty exercising
  • headaches
  • insomnia
  • irritable behavior
  • low energy
  • memory problems

Evidence suggests that a balanced and diverse diet might contribute to better health overall. A less diverse or less balanced gut can have a negative impact on health.

Different foods make us feel and behave in a different way. Our stomach, the place where food is processed, affects brain chemistry. While some food - such as fruit or vegetables - create balance, others type of food interferes with this balance. Plus, overconsumption of fats, carbs, and proteins can limit your digestive efficacy. Add on problems with food allergies, inflammation in the digestive tract, age, and a fluctuating emotional state...and you have many obstacles to healthy digestion.

Furthermore, bacterial proteins are connected to toxins that stimulate dysfunctional responses of the immune system. In more general terms, gut microbes can produce hormones and neurotransmitters that are identical to those produced in our bodies. Bacterial receptors for these hormones influence microbial growth and virulence. When levels of bacteria are out of balance, the immune system goes wacky.

Each of these various mechanisms shape almost every region in the brain responsible for memory, mood, and cognition. What we eat – and how we digest foods – affects the quality of sleep and our reactions to stress. We’ve also found through our medical practice that gut factors contribute to a range of disorders such as chronic fatigue syndrome and fibromyalgia.

But take hope!

For most generally healthy people aged 50+…systemic imbalances can be balanced out!

6 Best Supplements for Brain Fog

Can supplements cure brain fog?

We think so!

Dietary supplements can be used to help us achieve balance in our bodies. As we age, our bodies become less efficient at absorbing nutrients. It’s a fact! Plus, it can be difficult to get all the necessary nutrients from our diets: our plates are just not big enough. Brain fog supplements play an important role to get rid of brain fog. To be sure you’re getting what you need to eliminate brain fog, here are our specific suggestions.

1. Phosphatidylserine (PS)

Phosphatidylserine supports cognitive functions, especially memory of and focus. This is a phospholipid that contains both amino and fatty acids. PS works to regenerate nerve cell membranes and myelin – the fatty white tissue in the brain.

2. Acetyl-L-Carnitine (ALCAR)

Acetyl L-Carnitine is a recognized brain booster and memory enhancer. It is also used to support weight loss and has been known to increase energy. ALCAR is a natural dietary supplement derived from L-Carnitine, a protein.

3. Essential fatty acids

Essential fatty acids are critical molecules that help promote the brain and its ability to perform. They also affect mood, behavior and inflammation. Two essential fatty acids, linoleic and alpha-linolenic, cannot be synthesized in the body and must be obtained from food. If you’re not eating loads of leafy vegetables, fish, walnuts, or raw, organic seed oils...a supplement can help fill the gap.

4. Activated B vitamins

Good levels of B vitamins actually contribute to high brain levels of concentration! NOTE HERE: Vitamin B6 supplements taken alone or combined with vitamin B12 are not effective in the improvement of cognitive function for those who already experience dementia.

5. Digestive enzymes & probiotics

Digestive enzymes support the proper breakdown of food in the gut. In this way, probiotics and digestive enzymes can directly decrease cloudiness caused by slowed to blocked digestion. The result? Lower psychological distress, increased brain processing capability, and improved mood.   

6. Magnesium

Magnesium deficiency can be an underlying cause of brain fog. Magnesium supplements can help improve cognitive factors, such as memory, learning, recall, and cognition. Magnesium can also address insomnia, and reduce symptoms of depression. The result? Overall brain fog reduction.

Naturally Getting Rid Of Brain Fog

Unfortunately, experts have not yet identified an objective laboratory test that measures brain fog. Instead, “brain fog” as a condition is through to be a subjective state. Therefore, a clinical diagnosis will be based on careful history and exclusion of medical illness that presents with similar symptoms.  

Talk with your doctor about effective ways to address brain fog. We have found that the best way to clear up brain function is through lifestyle change:

  1. Get adequate amounts of REM sleep at night.
  2. Exercise daily for at least 20-30 minutes.
  3. Consume only brain-friendly foods OR add a brain supplement to your diet.
