What is the Origin of Neuroinflammation Signs?

The term is a compound of "neuro," referring to the nervous system, and "inflammation," the body's protective response to injury or infection, with "signs" emphasizing the clinical detectability of this process. This field emerged from the growing understanding that brain function is not immune to peripheral inflammatory processes and is central to chronic disease research.

What is the Mechanism of Neuroinflammation Signs?

Systemic issues, such as chronic gut dysbiosis, uncontrolled metabolic syndrome, or persistent stress-induced cortisol dysregulation, can trigger the release of inflammatory mediators that cross the blood-brain barrier. Once in the brain, these cytokines activate microglia, leading to a cascade of localized inflammation that impairs synaptic function and neuronal communication. Clinical assessment often involves measuring peripheral inflammatory markers as proxies for this central process.

Neuroinflammation Signs

Meaning

The clinical and biochemical indicators of an inflammatory response occurring within the central nervous system, characterized by the activation of resident immune cells, primarily microglia and astrocytes. These signs include elevated levels of pro-inflammatory cytokines in the cerebrospinal fluid or blood, which correlate with symptoms such as cognitive decline, persistent brain fog, and mood dysregulation. Neuroinflammation is a key pathway linking systemic health issues to neurological symptoms.
