Although it seems like a condition on its own, brain fog is actually a symptom of a variety of other medical conditions. It’s characterised by a series of issues including trouble concentrating, forgetfulness, lack of motivation, and confusion.

Here are some common things that could be causing your brain fog.

Although this list can be helpful to reference, if your brain fog is severe and is making it difficult for you to go about your daily life, you may want to talk to your doctor.

Anxiety could be causing your brain fog

Although anxiety can have an easy-to-identify cause, it can also be chronic and seemingly caused by nothing, making it more difficult to recognise.

Anxiety can cause you to experience many symptoms of brain fog, including difficulty concentrating and muddled thoughts.

Starting a new medication might be the culprit

Some medications and prescription drugs can cause people to experience memory loss and brain fog – especially in older patients.

Some types of drugs known for causing these side effects include anti-anxiety drugs, anti-seizure drugs, and narcotic painkillers.

Insomnia can affect your short-term and long-term cognitive abilities

Insomnia can cause you to feel confused and it can impact your sense of judgment and memory.

Insomnia can also have physical side effects such as an increased risk of having a stroke, asthma attacks, seizures, high blood pressure, and heart disease, according to Healthline.

A lack of iron in your diet might be the cause of your brain fog

Iron helps your body transport oxygen from your lungs to the rest of your body. So when you don’t have enough of it, you can experience several worrying symptoms, including brain fog.

To diagnose an iron deficiency, you typically need to take a blood test, so it’s important to talk to your doctor if you’re experiencing brain fog alongside other symptoms such as cold hands and feet, a fast heartbeat, and a sore tongue.

A vitamin-B12 deficiency might be to blame for your brain fog

Difficulties with thinking and reasoning are just one of a host of symptoms of a vitamin B-12 deficiency. Some other symptoms of this deficiency include balance problems, weakness, fatigue, and numbness or tingling in the hands, legs, or feet, according to Harvard Health.

Older individuals experiencing dietary changes or a decreased food intake as well as strict vegetarians and vegans who are not consuming enough of the vitamin are at higher risk of developing this deficiency.

It could be related to chronic fatigue syndrome

Your brain fog might be related to fibromyalgia

According to the American College of Rheumatology, fibromyalgia is “a common neurologic health problem that causes widespread pain and tenderness throughout the body.”

Those with fibromyalgia who experience brain fog oftentimes use the term “fibro fog” to describe the symptom.

“My patients tell me that fibro fog feels like they have been taking cold medicine constantly. They have difficulty concentrating, finding words, holding conversations, feeling alert and remembering things,” Dr. Rob Keenan, assistant professor of rheumatology at Duke University School of Medicine, told the Arthritis Foundation.
