It’s often a symptom of something else, such as a viral infection or chemotherapy treatment. One root cause of brain fog could be inflammation, says Von Ah. Certain conditions can cause lots of ...
Brain fog is a common symptom in many illnesses where chronic pain is a major component. [26] Brain fog affects 15% to 40% of those with chronic pain as their major illness. [27] In such illnesses, pain processing may use up resources, decreasing the brain's ability to think effectively. [26]
This underlying cause is reversible if you quit the meds, but other reversible causes might not be so obvious. Depression or major stress could cause impairment to show up in testing, too, Boyle says.
Brain fog is not a condition in itself, but "is very likely to be a sign or symptom of another issue," says Dr. Freda C. Lewis-Hall, chief patient officer at Pfizer and co-editor of the book ...
Other symptoms include the feeling of pressure in the brain, mostly around the frontal lobe area, headaches or migraine headaches, ear pain, ear fullness and possibly tinnitus. [citation needed] Fluctuations in weather also affect sufferers, in particularly hot weather and barometric pressure changes.
The first publication to document a change in pain perception associated with the weather was the American Journal of the Medical Sciences in 1887. This involved a single case report describing a person with phantom limb pain, and it concluded that "approaching storms, dropping barometric pressure and rain were associated with increased pain complaint."
The foundation cited a 2023 study of more than 15,000 migraine sufferers in Japan that linked an increase in headaches during barometric pressure changes, humidity and rainfall.
A pH outside of the range the brain can tolerate will also alter LOC. [9] Exposure to drugs (e.g. alcohol) or toxins may also lower LOC, [3] as may a core temperature that is too high or too low (hyperthermia or hypothermia). Increases in intracranial pressure (the pressure within the skull) can also
