Abstract

SUMMARYForty-seven cases of peripheral, spinal and cerebral diseases are reported in which metabolic deficiency as a pathogenic factor is either certain or highly probable. The concept of "avitaminosis" is enlarged to the idea of "neurometabolic crisis" which may be brought on not only by vitamin deficiency, but also by other factors involved in metabolism.Finally, high vitamin diet is recommended to be used in all cases of a similar nature, even with unknown etiology, and as an accessory treatment in cases with specific etiology.
