BRAIN FOG
Confusion, forgetfulness, a lack of focus and reduced mental clarity
BRAIN FOG
What is “brain fog”? – A quick perusal of the www. yields more than one hundred posts on the subject, but none is of sufficient clarity to satisfy a would-be “scientist”. Evidently, it is an extremely common condition, because each of the health-related websites has a page devoted to it. However just as evidently, it is an ill-defined condition, which everyone seems to understand, but regarding which no one has a definitive definition.
No one has proven a cause of brain fog and no one, thus far, has been able to provide a solid proposal for eliminating it.
Characteristics of brain fog
Google says “Brain fog is characterized by confusion, forgetfulness and a lack of focus and mental clarity: this can be caused by overworking, lack of sleep, stress and spending too much time on the computer”. It also says “a deficiency in several fields would explain fog, including vitamin D, vitamin B-12, Iron, Omega-3 fatty acids, Magnesium, Vitamin C and Choline”.
Other sources state that the condition is typically characterised by issues like slow or sluggish thinking, difficulty concentrating, distraction and finding it difficult to put your thoughts into words.
Brain fog may interfere with work or school performance, making it more difficult to complete tasks.
Brain Fog is a temporary condition, which can be diagnosed, treated and eliminated.
Is brain fog a medical condition?
The Cleveland clinic says “Brain fog” is a term for “a range of symptoms that cause cognitive impairment”, affecting the ability to think clearly, focus, concentrate, remember and pay attention”. It continues: “Like its name, these symptoms cloud the mind and make it difficult to perform routine tasks like holding a conversation, listening to instructions or remembering the steps of something you’re doing.”
Everyday health, in what is perhaps, the best statement I found on the web, quotes Shehroo Pudumjee, PhD, a neuropsychologist at the Cleveland Clinic Lou Ruvo Center for Brain Health in Las Vegas, who says “Brain fog isn’t something doctors diagnose their patients with. Brain fog is a broad term used to describe some common cognitive symptoms that folks face. These can be varied, but generally center around the idea that your thinking or memory isn’t as efficient or effective as it used to be.”
Web MD says that “Brain fog” isn’t a medical condition. Its website suggests that “Some kinds of drugs -- over-the-counter and prescribed -- can cause brain fog” and it mentions confusion due to chemotherapy, menopause, chronic fatigue syndrome, depression, lack of sleep and various infectious conditions………….
Every other source I found on the web makes a similar statement, with differing terms, various etiologies (causes) and varying lists of symptoms; but none ventures a definitive opinion regarding etiology, investigations or therapy.
Etiology (the cause) of brain fog
On the web,opinions regarding the cause of brain fog, are as diverse and as poorly conceived as the descriptive statements: chronic stress, poor sleep, hormonal changes of menopause, vitamin deficiencies, dietary quirks, illness, chemotherapy, drug reactions, allergic reactions, chronic illness, vitamin deficiencies, heavy metal poisoning etc. are mentioned, but no proof is provided, no investigations are suggested and no therapy is proposed.
Some claim that the condition is related to “anemia, depression, diabetes, migraine, hypothyroidism, autoimmune diseases, like lupus, rheumatoid arthritis, Sjögren’s syndrome, and multiple sclerosis, dehydration and viral infections like COVID-19”.
No one however has placed a finger firmly upon any single etiology.
MY OPINION
It is time to sort this out: brain fog is such a ubiquitous complaint and is associated with so many conditions that the cause has to be aberration of some very basic metabolic function, disturbance of which can be triggered by a multiplicity of states and conditions.
