A prominent figure in modern holistic health, Edgar Cayce gave numerous psychic readings on the causes and treatment of epilepsy. In contrast to mainstream medicine that concentrates almost exclusively on the brain as the sole dysfunctional organ in epilepsy, the Cayce readings focus primarily on pathology in peripheral systems (especially endocrine glands, the autonomic nervous system, and the abdominal lymphatic system) which in turn cause or contribute to brain seizures. Treatment options flow naturally from this view of causation and pathology with physiotherapy, diet, and medicine forming the core of the therapeutic approach. However, even with the strong physical/biological emphasis in the readings, there is also an inherent holistic emphasis that includes spiritual and mental (i.e., soul) involvement in the causes and treatment of epilepsy.
