neuro-immune to immune-deficiency
Just to further clarify, I think you are saying that a neuro-immune state can progress into an immune-deficiency stage? So then hang on? That would make sense to me, but just want to check to see if that's what you mean.
The neuroimmune problems may be the result of all the viral co-infections which creates a downward spiral: Immune deficiency allows viral infections which causes neural damage - some of which impacts the neuroimmune system. Neuralimmune issues further suppress normal immunity and then it's time to hang on! Shane
