Brain Fog

April 17, 2015

Cognitive dysfunction
From Wikipedia

Cognitive dysfunction (or brain fog) is defined as unusually poor mental function, associated with confusion, forgetfulness and difficulty concentrating.[1][2] A number of medical or psychiatric conditions and treatments can cause such symptoms, including Heavy metal poisoning (in particular mercury poisoning),[3] menopause and sleep disorders (including disrupted sleep).[2]

The term brain fog is not commonly used to describe people with dementia or other conditions that are known to cause confusion and memory problems, but it can be used as a synonym for sleep inertia or grogginess upon being awakened from deep sleep.


Treatment generally involves correcting any underlying medical conditions. For example, if the patient is found to be suffering a form of thyroidism, the mental declining effects associated with thyroidism can be corrected with thyroid hormone replacement therapy. Additionally, occupational therapy may be helpful for some people. Neurofeedback can improve symptoms for some people.
