The thyroid gland is important for your metabolism. It produces the T3 and T4 hormones that are responsible for the exchange of energy between cells. In case you have a thyroid gland insufficiency your hormones can also get affected.

The altered levels of the thyroid hormones can make you have a brain fog constantly. That is why it would be better to ask your doctor to prescribe you hormones to ease the brain fog symptoms.

4 – Fibromyalgia

It’s a new disease that could give you intense pain to your muscles and joints. Lately, it got associated with the brain fog condition, as many patients experience a lack of cognitive functions and a blurry mind.

5 – Sleep Pattern Changes

People tend to work more and more hours throughout the week. Standing in front of the computer screen may give more light to your eyes and reduce the normal melatonin (the sleep hormone) secretion in your brain.

The changes in sleep pattern, either towards insomnia or the oversleeping direction, can give you a brain fog that lasts for as long as the symptoms of sleep disorders are present.

6 – Depression

Modern life can be harsh for everybody. Depression is among the common mental health conditions, with millions of people suffering around the world.

It has been apparent that depression acts to the chemical receptors in your brain, decreasing the serotonin levels to the lowest point. Brain fog is the syndrome following the depression in many people, giving them reduced cognitive function and increased mental fatigue.

7 – Stress and Anxiety

People who work in high-end companies and other competitive industries, need to outperform every single day. Competing for the best salary and the best possible project outcomes, or even the fear to get fired can increase stress and anxiety to unprecedented levels.

Stress and anxiety are also increasing the blood levels of cortisol and adrenaline, which can cause brain fog to stressed people.

8 – Migraines

Many patients come to the doctor complaining about constant migraines. Brain fog has a direct relation to the persistent migraines, especially the ones that cannot cure with the use of proper medications.

Time has shown that migraines make things worse for patients who suffer from underlying medical conditions such as asthma or ataxia. Brain fog usually refers to their inability to use their memory right in a specific time frame.

9 – Diet

Nutritionists around the world offer diets adjusted to any lifestyle. However, a difficult diet and exercise program like the Atkins one (cutting all carbs at once) could be the reason to have brain fog. The lack of carbs can reduce glucose, which is the fuel of your brain.

Blood glucose levels are important to give you cognitive clarity, better attention, and focus levels. Getting your body deprived of any type of sugar can give you memory problems and mental function issues, described as brain fog.

10 – Cancer

Patients suffering from cancer can also experience brain fog. It’s not only the tumor that needs sugar to feed itself, but the medications and radiation received that can give you a strong headache and attention deficit- the well-known brain fog.

Things may get better for people who have cancer when they decide to get less interventional treatment for their malignancies. However, brain fog keeps coming even though you remain free of cancer.

11 – Reduced oxygenation during sleep

It is a syndrome known as sleep apnea. Patients who have this kind of sleep disorder have their air tubes blocked while being asleep. That makes them wake up several times through the night when the brain has less oxygen than necessary for healthy functioning.

When you have sleep apnea you are probable to suffer from brain fog during the day. Your attention could become reduced and experience memory issues as well as stress and anxiety. 

12 – Chronic Inflammation

A neurologist is a competent doctor to give you the best treatment for your head injury and decide if the brain fog syndrome needs further investigation.

14 – Multiple Sclerosis (MS)

It is a neurodegenerative disease affecting the motor neurons giving a permanent moving impairment to patients suffering from it. Lately, specialists have proved that MS can also be the root of mental and cognitive issues, known as brain fog.

Any damage to the acoustic or balance nerves in your ears could be responsible for brain fog. Many recognize it as vertigo which is strong dizziness that a person feels after a particular environmental stimulus.

Brain fog can be the reason why people who feel dizzy cannot memorize things or show attention disorders and inability to focus.

16 – Substance abuse

Persons who drink much alcohol and take drugs are more vulnerable to develop brain fog. All these substances block the normal function of brain cells and give you dizziness and reduced focus on thinking important things including work changes.

The quality of your foods determines the possibility to develop brain fog. Dehydration (lack of water) can also make you feel dizzy or disoriented and unable to perform thinking.
