The Cerebro-spinal Fluid in Encephalitis Lethargica

Extract

Encephalitis lethargica, or epidemic encephalitis as it is now usually called, is becoming more generally recognized throughout the world, and while diagnosis is usually easy in those cases with a clear history, and who show the “encephalitic syndrome” to a marked degree, much confusion has arisen in the case of some patients who have shown clinical features which have led observers to arrive at a diagnosis of this disease when later investigations have shown that this conclusion has not been a correct one.
