Brain Fog: Symptoms, Causes, and Treatment

Have you ever been in a situation where you have trouble processing a thought or have fuzzy thinking? Then you may be suffering from brain fog.

Brain fog is not a medical condition but forms a group of symptoms in which a person has difficulty thinking, inability to focus on a single thought, unable to make a correct sentence out of his mind and think clearly . These symptoms can arise due to a medical condition or a poor high-stress lifestyle.

What is Brain Fog?

Brain fog is not a medical condition, but a group of symptoms of cognitive dysfunction, where a person lacks sharp memory or lacks focus. A person with brain fog will have difficulty processing thoughts, recalling memories, difficulty concentrating or paying attention, mental fatigue, etc.

Although not serious but very common, brain fog does not affect a person’s intellect, deteriorate or develop, but a person may have difficulty doing regular work and may suffer from depression and low self-esteem (a feeling of not being to be herself/herself).

Some may also suffer from speech and language disorders where they may have difficulty making sentences using their thoughts.

What Are the Symptoms of Brain Fog?

Brain fog works differently in people. It can affect all age groups, from a school-aged child to a mature adult, and also in old age. A person suffering from brain fog may have one symptom or may have several symptoms together related to the severity of the condition. Mentioned below are some of the common symptoms of brain fog:

  • Decreased concentration
  • Memory impairment
  • Blurry or faded thoughts
  • Extreme tiredness and drowsiness
  • Feeling demotivated
  • Negative self image
  • Poor performance at school and work
  • Depressed mood
  • Unable to form sentences using words or inability to understand a simple sentence
  • Cannot focus on a single target
  • Unable to carry out a plan, solve a problem, or organize things

What Are the Causes of Brain Fog?

According to research, there are several reasons and conditions responsible for brain fog. It is necessary to identify the cause and start early treatment of the underlying cause. Some causes responsible for brain fog are listed below:

extreme stress

It is believed that an excessive amount of stress can lead to brain fog. Chronic stress can put too much strain and pressure on the brain. Stress can lead to increased blood pressure, mental fatigue, inability to focus, severe headaches and can also lead to depression. This can lead to your brain not functioning properly, losing focus and concentration.

Vitamin B12 deficiency

A vitamin B12 deficiency can lead to brain fog. Vitamin B12 is only found in milk, fish, eggs, etc. and not in vegetable sources. Vitamin B12 makes it possible to improve brain function. B12 deficiency can lead to anemia (low hemoglobin in the blood), which causes fatigue, memory problems, tingling in the hands and feet, etc.

A long-term deficiency can lead to an irreversible condition. Vitamin B12 deficiency can be due to insufficient dietary intake, impaired absorption, medical conditions, etc.

Decreased sleep

Decreased sleep hours and disrupted sleep patterns of an individual can lead to impairment of brain function. Getting enough sleep of 8 to 9 hours is essential for healthy brain function. Decreased sleep also causes mental fatigue and loss of concentration.

Hormonal imbalance and change

An imbalance in the hormonal regulation in the body can lead to brain fog. During pregnancy, the levels of estrogen and progesterone rise. The elevated levels of these hormones can impair cognitive function and memory.

During menopause, decreased estrogen levels can also affect brain function, impairing recent memory and clouding consciousness. An imbalance of thyroid hormones T3, T4 and TSH can also lead to a decrease in brain function and forgetfulness.

Medicines (drugs)

It is believed that taking some specific medications can lead to brain fog. Drugs such as anticholinergics block neurotransmitters in the nervous system, which in turn reduces brain function. Anticholinergic drugs that can cause brain fog are oxybutynin, diphenhydramine, amitriptyline, etc. A patient undergoing chemotherapy can also suffer from brain fog as chemotherapy drugs can suppress immunity and affect brain function.

Other medical conditions associated with brain fog include:

When to see your doctor

It is always advisable to see your doctor if you are depressed most of the time and have trouble concentrating or performing well at school/work. We always recommend sharing your thoughts and problems with people close to you instead of taking undue stress and straining your brain unnecessarily.

Because a single test in a hospital cannot diagnose brain fog, your doctor will run several tests and give you medications and behavioral therapy to improve your symptoms, which may take some time at first. your doctor will rule out the cause they suspect is responsible, such as diet, mental state, medical conditions, drug history, etc.

Different diseases have some similar symptoms. Tell your doctor about any medical or surgical history. Show them any prescription of medications you’ve taken recently. Tests such as CT, MRI, TFT, blood count (to rule out infection, blood sugar, anemia, etc.) can help your doctor determine the true cause of brain fog. Your doctor may also perform some antigen-antibody tests to rule out allergies and check your sleep patterns to rule out a sleep disorder.

What is the treatment for brain fog?

Treating a brain fog takes time and effort, as it is essential to treat the underlying conditions first. Here are a few things you should know to cure brain fog and improve brain function:

Get enough sleep

Improve your sleep patterns, as sleep deprivation can hinder your brain function. Make a schedule of at least 8 to 9 hours of sleep on time. A regular sleep pattern helps with healthy brain function and sharp memory. Late and irregular sleep can lead to decreased concentration and mental fatigue.

free your brain

Reduce stress as much as you can. Reduce your workload if your brain is overworked, making it harder for you to concentrate.

regulate consumption

Avoid the intake of alcohol, cigarettes and excessive amounts of caffeine.

Treat your low blood volume

For a person suffering from low hemoglobin in the blood (anemia), it is crucial to take medications and supplements to treat anemia. Increased iron supplements can help produce red blood cells, which helps improve your brain function.

regular exercise

Regular exercise can improve blood circulation, normalize blood pressure, make you active and improve brain function. Obesity is also believed to be responsible for causing brain fog.

Find free time

Find pleasure in pursuing hobbies, socializing or playing games like solving puzzles, etc. as it helps to reduce stress and improve concentration.

healthy diet

Improving the diet or healthy eating is essential to improve mental health. Foods rich in adequate amounts of protein, calories, vitamins, etc. can help sharpen memory. Regularly eating fruits, vegetables, eggs, milk, and fats can provide enough minerals to treat brain fog. Drink plenty of water or fluids to correct dehydration.
