What is Brain Fog?

Brain fog isn’t a medical condition itself, but rather a symptom of other medical conditions. It’s a kind of cognitive dysfunction involving lack of mental clarity, inability to focus, poor concentration, and memory problems.

It’s also described as a type of mental fatigue. The reality is that it can interfere with school or work activities if left untreated. As people get older, their chances of suffering from brain fog increase.

People’s experiences of brain fog vary widely. Some describe it lasting for as little as five minutes, while others insist they’ve suffered from it for many years.

Keep in mind that while the symptoms are frustrating, they’re often an indication of something more serious. In line with this, some describe brain fog as a subset of an underlying physical, chemical, or emotional imbalance.

Why Does this Happen?

Now we’re more aware of the symptoms and how they affect us, it’s time to look at why this occurs.

It’s helpful to note that brain fog symptoms are all examples of poor frontal lobe function. The frontal lobe is essentially what makes us human. It’s responsible for critical thinking, decision-making, and executive function.

If we get stressed, blood flow to the frontal lobe is decreased and sent instead to the midbrain or the limbic system. This causes lowered activity in the frontal lobe and increased activation in the limbic system.

During this process, we move away from the ability to think ‘straight’. Instead, the brain goes into a ‘fight or flight’ response, because it’s in survival mode. Instead of having a growth mindset that’s capable of critical thought, a fearful response is activated.

When this happens, people become emotional and reactionary. They’re no longer able to process new information in a calm manner. Of course, this prevents the brain from functioning as it should.

Brain Fog Causes

There are multiple possible causes of a foggy brain. In general, the symptoms of brain fog are a result of inflammation, usually mediated through oxidative stress.

It can occur with age, as a result of a medical condition or lifestyle factors. Bad diets, lack of exercise, not enough sleep, and high-stress levels all contribute to a person’s risk of suffering from brain fog.

Brain fog can be frustrating and confusing. But the good news is that there are ways to cope when it happens. keep reading to find out more about the causes of brain fog.
