I do think that right now in medicine there is a problem of not being able to see the forest for the trees. Our medical system is designed to break down and categorize disease by system (nervous, gastrointestinal, cardiovascular, etc.) Everyone is seeing one aspect of the illness, and missing the others. The immunologist sees an immune system problem, the infectious disease specialist sees an infection, and the neurologist sees neurological deficits. We need to look at the big picture - and we aren't good at that anymore.
