Stop losing your mental peace over why it happens. Read on to know the causes of brain fog and effective ways to treat it.

Brain fog is essentially a cognitive fog that temporarily clouds mental clarity and impacts daily functioning, senior neurologit Dr Naveen Kumar tells Health Shots.

What are the causes of brain fog?

The cognitive fog can be influenced by many factors including:

1. Inadequate sleep

Insufficient rest can leave you feeling tired the whole day, and it also disrupts neurotransmitter balance, affecting cognitive processes.

2. Dietary factors

Poor nutrition, including deficiencies in vitamins and minerals, can contribute to cognitive fog. A 2021 study published in the Nutrients showed that a vitamin B12 deficiency, which helps in healthy function of the brain, can cause brain fog.

3. Chronic stress

Prolonged stress triggers the release of cortisol, which can impair cognitive functions and contribute to brain fog.

4. Health conditions

Conditions like chronic fatigue syndrome or fibromyalgia are often linked to persistent brain fog, says the expert. As per Harvard Health Publishing, Covid-19 also has a connection to brain fog. Following Covid-19, you may experience lingering symptoms such as body aches, fatigue, inability to work out, headache and difficulty in sleeping. Some of these issues may be because of permanent damage to organs such as the kidneys, lungs or heart. When the damage to these organs happen or you experience the symptoms, they can impair thinking and memory and ultimately cause brain fog.

5. Medication impact

Certain medications such as antihistamines usually help to treat allergy symptoms, stomach issues or colds, but they may have cognitive side effects.

6. Hormonal changes

Fluctuations in hormones, like during menopause, can contribute to cognitive fog. When there is a drop in estrogen levels during menopause, it can lead to poor concentration, among other things.

What are the common signs of brain fog?

People experiencing brain fog may find it challenging to articulate thoughts, make decisions or perform mental tasks that would typically be routine.
