Does Depression Cause Brain Fog?

People who have been diagnosed with clinical depression may experience a variety of cognitive challenges. Some people refer to the combination of these symptoms or changes as brain fog. Although brain fog is not a clinical diagnosis, it is a common group of symptoms that affect the way you remember, think, and concentrate. It’s possible to lose your train of thought mid conversation or execute ordinary tasks without challenge. 

Symptoms Of Brain Fog In Depression

For people with depression, brain fog symptoms are called cognitive dysfunction. Not every person who has depression experiences the same cognitive symptoms, let alone brain fog, with the same intensity. Generally speaking, depression affects the brain differently, and brain fog can manifest in the following ways:

• Challenges with memory: You may experience difficulty remembering what you wanted to do or forget what you were going to do. It may be necessary to write things down to remember them, or perhaps you may find that you lose things or miss important dates regularly.
• Delayed reaction time: It may take you longer to complete tasks and manage time more efficiently with cognitive changes. 
• Difficulty paying attention: It may be more difficult for you to complete a thought, follow conversation, finish tasks at work, or focus on a TV show, book, or movie. 
• Trouble with executive functioning: Your ability to make decisions may be challenging, which can potentially cause you to constantly worry about different outcomes. It may also be harder for you to multitask.

Cognitive challenges are not the only symptoms of depression. Brain fog has other causes and is not solely reserved for people with depression. In order to receive a diagnosis for depression, though, a healthcare professional will try to identify at least five out of nine formal symptoms. 

What Are Formal Symptoms Of Depression?

Although brain fog can be a symptom of depression, it is not categorized as a formal symptom. Formal symptoms of depression include:

• Reduced ability to enjoy special or everyday activities
• Appetite changes (eating less or more than usual)
• Low energy or lack of motivation
• Changes in sleep pattern (sleeping more or fewer hours than usual)
• Cognitive changes (including brain fog)
• Changes in the way you move (such as slower or quicker than usual)
• Thoughts of self-harm and death

If a doctor cannot determine that depression is the cause of brain fog, they may want to explore other options. Thyroid dysfunction, brain injuries, anxiety, and COVID-19 can all cause brain fog. 

How Do You Treat Brain Fog?

If depression is the cause of brain fog, you have to address depression, as treating brain fog does not get to the root of the problem. Additionally, untreated depression will only cause symptoms to worsen or intensify. Most health experts agree that psychotherapy is the first line of treatment for depression. Behavioral therapy, dialectical behavior therapy, interpersonal therapy, psychodynamic therapy, and cognitive behavioral therapy are just a few options to help treat depression.

Cognitive behavioral therapy, according to experts, can be particularly helpful in reducing brain fog in people with depression. Lifestyle modifications may also reduce brain fog and improve other symptoms of depression. Depending on your preferences or needs, these lifestyle modifications may include:

• Limiting your intake of caffeine, sugar, and alcohol
• Engage in daily physical activity, such as walking, yoga, or strength training
• Focus on a nutrient-dense diet
• Try to manage stress by engaging in meditation or deep breathing exercises

Brain fog can be a symptom of depression, manifesting differently for different people. You may experience difficulty remembering things, following instructions, or focusing. Treating your depression first may help get rid of brain fog. Work with healthcare professionals in order to get the help and support you need.
