Brain Fog Symptoms, Causes, Treatment, Diagnosis & More

Are you having a hard time making yourself focus? Maybe you often space out or lose mental clarity that you’re unable to accomplish your tasks. Brain Fog happens when you experience mental fatigue that greatly affects your ability to think and perform well. Although not a medical condition, brain fog can be a real problem or indicate something more serious. This article will help you learn about brain fog symptoms, causes, treatment, and other related information you need to know.


Brain fog is a general term that refers to a set of symptoms affecting mental processes such as memory and concentration. The Diagnostic and Statistical Manual of Mental Disorders (DSM) has historically used it (as its other term, “clouding of consciousness”) in its definition of delirium. Later on, the DSM-III-R and the DSM-IV replaced the term with “disturbance of consciousness”.  

Quite common, brain fog can affect people of any age. It can also lead to various problems like depression, anxiety, and even delinquency. Despite its prevalence, brain fog is still not considered a condition at present. It’s a symptom that has recently been added to those connected with COVID-19.


Brain fog symptoms vary but include common ones shared by individuals with the same conditions. These are some of them: 

  • Inability to Focus or Concentrate
  • Chronic Fatigue
  • Insomnia
  • Forgetfulness
  • Irritability
  • Feelings of Confusion/Disorientation
  • Cognitive Problems
  • Negative Feelings

All serious brain fog symptoms are usually more severe than when you have a typical brain fog (forgetting your keys or having a cloudy mind every Monday, for example). They are consistent and have a much greater effect on you.


As previously mentioned, brain fog is not a medical condition, but a symptom of one. There are many different medical conditions which can cause brain fog. Like brain fog symptoms, triggers depend on the person’s situation, health, and other significant factors. The following are some of the most common causes of brain fog:

  • Stress (physical or psychological or both)
  • Hormones
  • Unhealthy Sleeping Habits
  • Lack of Exercise
  • Diet 
  • Prescription Medications
  • Dehydration
  • Health Problems
  • Natural Occurrences (e.g. pregnancy, menopause, etc.)
  • Mental Health Conditions


Aside from the fact that it’s often associated with medical conditions, brain fog is only best understood by knowing someone’s particular experience. There is no specific test that can determine a brain fog diagnosis. 


If brain fog is triggered by an ailment, professional help is necessary. Proper treatment alone is the way to deal with both brain fog and the condition that caused it. Still, there are a few remedies and temporary solutions you can try for yourself. For instance, getting proper sleep, moving your body more, eating right, drinking enough water, managing stress (through resting well, meditation, etc.), and engaging in a hobby are all helpful.

As humans, it’s completely normal for us to experience brain fog. We may have different brain fog symptoms and not have only one diagnosis. Some experience brain fog because of a mental health condition while others get it from extreme stress. No matter which form, it’s very important to take brain fog seriously. You need to seek professional advice to understand what your brain fog symptoms indicate. You can only recover best once you know what your specific case is and how you should properly deal with it. There are many available qualified physicians you can trust to help you overcome brain fog. Treatment and a healthy lifestyle are essential.
