 Cognitive dysfunction (also known as brain fog) is the loss of intellectual functions such as thinking, remembering, and reasoning of sufficient severity to interfere with daily functioning. Patients with cognitive dysfunction have trouble with verbal recall, basic arithmetic, and concentration. Cognitive dysfunction (also known as brain fog) is the loss of intellectual functions such as thinking, remembering, and reasoning of sufficient severity to interfere with daily functioning.

-According to the Marshall Pathogenesis, cognitive dysfunction is caused by microbes. More severe forms of cognitive dysfunction are seen in diseases such as Alzheimer's, diseases for which there is strong evidence of a bacterial etiology. Often associated with chronic fatigue syndrome,(({{pubmed>long:17605583}})) cognitive dysfunction is also seen in patients with multiple sclerosis,(({{pubmed>long:16847772}})) depression,(({{pubmed>long:17605583}}))  fibromyalgia,(({{pubmed>long:11286668}})) and dozens of others diseases.+According to the Marshall Pathogenesis, cognitive dysfunction is caused by microbes.

 Like all symptoms of inflammatory disease, cognitive dysfunction may temporarily increase during periods of immunopathology. Cognitive dysfunction can be managed using the [[home:mp:managing_immunopathology|generic strategies for managing immunopathology]], and should resolve over the course of the Marshall Protocol (MP). Like all symptoms of inflammatory disease, cognitive dysfunction may temporarily increase during periods of immunopathology.

-  * **cognitive and functional decline often follow severe sepsis** – The researchers focused their attention on 516 individuals who survived hospitalization for severe sepsis and 4517 who survived a nonsepsis hospitalization. The average age of survivors at hospitalization was 76.9 years. Following severe sepsis hospitalization, but not nonsepsis general hospitalization, there was a significant increase in the odds of developing both cognitive and physical dysfunction that persisted throughout the 8-year follow-up period, the researchers report.(({{pubmed>long:20978262}})) +  * **cognitive and functional decline often follow severe sepsis** – The researchers focused their attention on 516 individuals who survived hospitalization for severe sepsis and 4517 who survived a nonsepsis hospitalization.

-  * **aging immune cells in animal models** – The decline in brain function associated with disease and old age could be due to the decline in the function of immune cells, which is likely caused by infection. As described in New Scientist, prompted by studies suggesting immune responses can help repair the nervous system, Jonathan Kipnis and colleagues at the University of Virginia created mice that lack CD4 cells, a kind of T-cell. They found the mice performed extremely poorly in tasks involving learning and memory, but when they were injected with CD4 cells from healthy mice, their memories improved.(({{pubmed>long:15141078}})) Similarly, when he killed CD4 cells in healthy mice, their memory declined. Further animal studies by Kipnis and others show that learning new tasks triggers a mild stress response within the brain, which prompts CD4 cells to rally to the meninges, the membranes that surround the brain. Here, they release IL-4, which both switches off the stress response and tells brain cells called astrocytes to release brain-derived neurotrophic factor, a protein that enhances learning.(({{pubmed>long:20439540}})) Whether these animal studies are relevant to human learning and memory remains unclear, but there is some indirect evidence to support it. For example, many chemotherapy drugs suppress the immune system, which might explain why some people with cancer develop "chemobrain" - a term used to describe the cognitive problems and memory loss associated with chemotherapy. Sluggish immune cells might also explain why our brains slow down as we age. "The number one cell affected by ageing is the T-cell," says Kipnis. "I'm not saying it's the only factor leading to age-related dementia, but it could definitely be one of them."+  * **aging immune cells in animal models** – The decline in brain function associated with disease and old age could be due to the decline in the function of immune cells, which is likely caused by infection.
