What are the major Causes of Brain Fog?


Do you have difficulties in concentration? Understanding, focusing, and remembering information may be challenging if one or more of these processes are not functioning properly. Stress and mental exhaustion may result from it. Brain fog may cause your difficulties focusing or feeling as though you cannot think clearly. It is a symptom that can accompany several medical diseases or specific life events but is not in and of itself a diagnosis. When patients mention having brain fog, they typically refer to problems paying attention and concentrating. Learning about the causes of brain fog and trying to deal with it effectively is good. In this post, you will look at some of the major causes of brain fog:


Even while the word ‘stress’ may seem common and relatively harmless, prolonged stress can disastrously affect your body. Your body triggers the sympathetic nervous system (SNS), sometimes known as the fight-or-flight reaction when it detects a stressful circumstance. Epinephrine is released in response to the stressor, which ultimately directs energy away from your body’s normal processes and toward the stressor. Your brain may become exhausted, making it challenging to think effectively and concentrate. When your brain feels fuzzy, it may be helpful to learn to manage your stress over time with interventions like meditation, exercise, or dietary modifications. You can also use the DMSO spray, which helps to eliminate the brain fog and maximize your energy.

Hormonal changes 

A person’s hormone levels alter naturally throughout their lifespan. Changes in hormone levels are known as hormone fluctuations. Research from 2018 suggests hormonal changes can also cause brain fog. Progesterone and estrogen concentrations rise throughout pregnancy. Short-term cognitive impairment and memory loss are possible effects of this alteration. According to research, a decline in estrogen levels after menopause can also lead to forgetfulness, lack of focus, and foggy thinking. So, whenever there is a hormonal change, it may lead to brain fog.

Poor sleep 

Do you sleep regularly? If not, then you have to face various health issues. Sleeping late at night and waking at abnormal timing is bad for everyone. As a human, you must rest for 7-8 hours. Brain fog might happen if you are sleep deprived for an extended period or because of a persistent disease like insomnia or sleep apnea. According to experts, sleep deprivation may cause certain brain regions to enter sleep-like cycles when an individual is awake. They add that sleep-deprived may also affect how well certain brain regions communicate and cooperate, contributing to mental fogginess. Using the DMSO nasal spray will make you feel better and sleep better, which supports fighting against brain fog.


One of the major causes of brain fog is taking some particular medication. Few drug and over-the-counter medications can spoil thinking. Call your doctor if you take medication and discover that you aren’t thinking as clearly as you should be or that you have suddenly lost your memory. Make sure to disclose all the prescriptions you take to them. The medical world is divided on the idea that sensitivity to various substances, both natural and synthetic, might potentially result in brain fog. Additionally, cancer and cancer treatment also lead to brain fog. It is common to experience what is known as “chemo brain” during and after cancer therapy. Although other medicines might also be related, chemotherapy is most frequently associated with it.

Food sensitivities and dietary deficits

The central nervous system and the production of red blood cells are aided by vitamin B12. Because of this, a B12 shortage will inevitably lower your energy levels and make you feel generally worn out. A vitamin D deficiency may also cause brain fog since low vitamin D levels are linked to cognitive decline. An unexplained dietary intolerance may also bring on your current state of confusion. For instance, inflammatory pathways might cause cognitive impairment due to gluten intolerance. Suppose any of these could be causing your brain fog. In that case, it can be determined using advanced blood work that analyses your nutritional levels, an elimination diet, or testing for food allergies or sensitivities.

Wrapping it up: 

Brain fog indicates that your food and way of life need to change. People with brain fog may feel that their thinking, understanding, and memory functions are not functioning properly. Try not to trigger the brain fog and once you have noticed the presence of brain fog, try to cure it fast.
