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,^[2] fibromyalgia 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,^{[citation needed]} but it can be used as a synonym for sleep inertia or grogginess upon being awakened from deep sleep.

[edit] Treatments

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.^{[citation needed]} Additionally, occupational therapy may be helpful for some people. Neurofeedback can improve symptoms for some people.^[4][5][6]
