Devices such as the Fisher-Wallace CES (Cranial Electrostimulation) is essentially 100% safe and at a one time cost of $695, can replace multiple psychopharmacologic agents, each with it's own cost and constellation of unpredictable side effects. At this time, several well designed studies from Harvard, Columbia, and others are demonstrating the efficacy of treating PTSD and TBI (traumatic brain injury) in returning Vets from the Gulf War whose anatomic and psychic stability have been damaged. Mostly younger, this population is intolerant of typical SSRI and anxiolytic drug side effects (eg. libido, ED, etc), and the cost of the 5 year lifespan unit is equivalent to only a few months of typical polypharmacologic treatment of these difficult patients. I think we'll be seeing this, too, as part of the pharma sunset.
