Hypothesis
Systemic inflammation may induce brain pathology.
Conclusion
Chronic systemic inflammatory diseases are associated with inflammatory changes in the brain of rodents and humans.
Supporting Evidence
- Risk factors for stroke include atherosclerosis, obesity, diabetes, and hypertension.
- Stroke risk factors are associated with peripheral inflammation.
- Corpulent rats and atherogenic mice show increased inflammation in the brain.
- Pilot data show that patients at risk of stroke may also develop brain inflammation.
- Chronic peripheral inflammation can drive inflammatory changes in the brain.
Takeaway
If someone has health problems like obesity or diabetes, their brain might get inflamed, which could lead to a stroke.
Methodology
The study used rodent models and PET imaging to assess brain inflammation and microglial activation.
Potential Biases
Potential bias due to small sample size and selection criteria for human participants.
Limitations
The clinical study had a very small sample size and only included patients without existing brain pathology.
Participant Demographics
Four subjects at risk of stroke with multiple risk factors and elevated CRP levels.
