Neuroinflammation and BrainFog – when inflammation becomes a cognitive veil
For many people with ME/CFS, brain fog is a central and burdensome symptom. It describes a state in which thinking, concentration, and memory are significantly impaired – as if a misty veil obscures cognitive clarity. Current research findings suggest that neuroinflammatory processes play a key role in the emergence of this cognitive fog. Belegt ✓
Microglia activation and pro-inflammatory cytokines
In the brain, microglia cells take on the task of immune surveillance. In ME/CFS, there is increased activation of these cells, accompanied by elevated release of pro-inflammatory cytokines such as interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α). Belegt ✓
Disruption of synaptic plasticity
Synaptic plasticity describes the ability of nerve cells to strengthen or weaken their connections depending on experience and activity – a fundamental prerequisite for learning and memory. The persistent presence of IL-1β, IL-6, and TNF-α can disrupt this plasticity by altering the signaling pathways between nerve cells and reducing the efficiency of synaptic transmission. Belegt ✓
Correlation with clinical complaints
These neurobiological changes offer a plausible explanation for why those affected report an ongoing sense of mental fatigue, confusion, and difficulty concentrating, despite adequate sleep and rest periods. Brain fog in ME/CFS is therefore not merely a subjective feeling, but can be correlated with objective inflammatory markers and functional changes in the brain. Plausibel ~
Outlook
A better understanding of the involvement of neuroinflammation in brain fog opens up new avenues for research. While current findings do not point to direct therapeutic recommendations, they underscore the importance of further investigation into immunomodulatory approaches and their potential influence on cognitive symptoms in ME/CFS.
