Cranial Electrotherapy Stimulation (CES) is used in the treatment of anxiety, depression, insomnia, and drug addiction; via a low intensity electrical microcurrent.[citation needed] CES is an alternative to drugs, which attempt to affect the brain via chemical processes. In the United States, CES equipment must be prescribed by a licensed independent provider (i.e., medical psychologist, nurse practitioner, physician or physicians assistant).
Because of an early focus upon sleeping disorders, CES was originally known as electrosleep therapy. CES is sometimes written "Cranial-Electro Stimulation," "NeuroElectric Therapy," and "Transcranial Electrotherapy."

[edit] How CES Works
Research conducted in the 20th century has demonstrated that the brain makes use of electrical activity; thus, one can affect mental functions by affecting the organ's electrical activity.
During CES, an electric current is focused upon the hypothalamic region; during this process, CES electrodes are placed behind the ear at the mastoid, or clipped to the upper portion of the earlobe, near to the face. CES treatment promotes an increase in endorphins; note, scientists remain unsure why this occurs. The current results in an increase of the brain's levels of serotonin, norepinephrine, and dopamine, and a decrease in its level of cortisol. When CES is effective, users are in an "alert, yet relaxed" state, characterized by alpha brain waves. http://www.quackwatch.com/01QuackeryRelatedTopics/ces.html
[edit] History
"Electrotherapy" has been in use for at least 2000 years, as shown by the clinical literature of the early Roman physician, Scribonius Largus, who wrote in the Compositiones Medicae of 46 AD that his patients should stand on a live black torpedo fish for the relief of a variety of medical conditions, including gout and headaches. Claudius Galen (131 - 201 AD) also recommended using the shocks from the electrical fish for medical therapies.
Modern research into low intensity electrical stimulation of the brain was begun by Leduc and Rouxeau in France (1902); in 1949, the Soviet Union expanded research of CES to include the treatment of anxiety as well as sleeping disorders.
In the 1960s and 1970s, it was common for physicians and researchers to place electrodes on the eyes, thinking that any other electrode site would not be able to penetrate the cranium. It was later found that placing electrodes behind the earlobes was far more convenient, and quite effective.
Electroshock therapy effectively raises brain serotonin, and low-dose electroshock treatments for depression are making a comeback for the treatment of difficult cases.
[edit] New Competing Devices
Electrical devices in psychiatry have not caught on until recently. With the strong arm of the prescription medicine industry backing medication, and the stigma of electrical devices for use on the brain (which many relate to electroconvulsive therapy ) companies that developed such devices had a difficult time receiving financial support for needed research. Now that public sentiment is beginning to change new electrical devices are emerging for the treatment of psychological disorders such as transcranial magnetic stimulation and vagus nerve stimulation. These devices may prove to be effective, however, the makers of Cranial Electrotherapy Stimulation devices have been experimenting and using electrical devices for years to treat millions of patients.
[edit] Effectiveness
Most users report a decrease in anxiety during treatment, and many other report a decrease in anxiety as much as two days later. Some users report a euphoric feeling; they report that their bodies feel "lighter", their thinking is clearer, and that they are more creative.
A minority of users require five to ten treatments to achieve any effect.
CES has been cleared by the FDA and is becoming more available, even as at-home treatment, and affordable, with rent-to-own plans. It is not highly marketed, as companies providing it are still quite small compared to pharmaceutical ones.
