A Neuroinflammatory Model for ME/CFS (a hypothesis)

Описание: Dr Angus Mackay talks with us about his theory that neuroinflammation is the cause of ME/CFS (and Long Covid related post-viral fatigue syndrome).
Presentation for MECFS Canterbury, 14th February 2024.

Angus hopes that as brain imaging techniques develop, the model will be used by researchers to explore and develop a better understanding of this debilitating disease.

The model revolves around a dysfunctional and inflamed hypothalamus, the master gland within the brain, and the stress-response centre within it, called the paraventricular nucleus (PVN), that responds to all significant stressors including viral and other shocks.

1:03:44 Questions
1:03:59 Is it a genetic susceptibility or does this susceptibility change over time? As many people report coping with many stressors, and then something similar happens that then triggers ME/CFS.
1:06:40 Example shared of a recent relapse caused by exposure to more sunlight when blinds were removed for cleaning.

1:13:35 Thank you Angus
1:15:18 We need researchers to explore and validate the model now
