Cranial electrotherapy stimulation: a safe neuromedical treatment for anxiety, depression, or insomnia.To the Editor: The Institute of Medicine's To Err is Human "To Err is Human: Building a Safer Health System" is a groundbreaking report issued in 2000 by the U.S. Institute of Medicine which resulted in an increased awareness of U.S. medical errors. The push for patient safety that followed its release currently continues. made headlines by estimating that medical errors account for between 44,000 and 98,000 deaths annually in the United States. Together with the subsequent quality dimension report, Crossing the Quality Chasm, the Institute of Medicine has brought patient safety into the spotlight. (1) The greatest variance of adverse events in medicine probably is due to medication errors. Today's primary care physician has a multitude of electronic devices such as personal digital assistants, software, and newsletters designed to help minimize medication error and promote safe medication practices. (2) Electronic therapeutic devices can actively reduce the number of medication errors by reducing the amount of medication needed to treat anxiety, depression, insomnia, and pain. Among the electromedical devices available to the ordinary office practice of general medicine is the cranial electrotherapy stimulation cranial electrotherapy stimulation NET, neuroelectric therapy, TCET,
transcranial electrotherapy Psychiatry A maneuver in which electrodes are placed on or near the ears to pass low level–less than that used in electroshock therapy–electricity (CES) device. CES is the noninvasive application of low levels of microcurrent (less than 1 milliampere mil·li·am·pere

n ) stimulation applied transcutaneously to the brain for therapeutic purposes. Physicians associate these devices with pain treatment centers and the management of chronic, severe pain, but CES can be efficacious for other conditions.
CES is a treatment modality that has been neglected by mainstream medicine for the treatment of anxiety, depression, or insomnia. Selective serotonin reuptake inhibitors Selective Serotonin Reuptake Inhibitors Definition
Selective serotonin reuptake inhibitors are medicines that relieve symptoms of depression.
Purpose (SSRIs) are known as the gold standard for the treatment of depression. However, CES is now more relevant because of recent government warnings on SSRIs [http://www.fda.gov/cder/drug/antidepressants/AntidepressanstPHA.htm and http://www.cnn.com/2004/HEALTH/03/22/antidepressant.warning.ap/index.htm]. Thus far, CES has not demonstrated any of these adverse effects. There is no shortage of antidepressant antidepressant, any of a wide range of drugs used to treat psychic depression. They are given to elevate mood, counter suicidal thoughts, and increase the effectiveness of psychotherapy. research, but today's peer-reviewed literature has a relative dearth of CES reports. The companies that produce these devices are small and as yet unable to support high-budget standards of double-blinded, randomized ran·dom·ize

CES in the United States has received Food and Drug Administration marketing clearance for the treatment of anxiety, depression, and insomnia. CES devices are sold over the counter in Europe and other parts of the world. Mooddisordered alcoholics have shown increased activity of the enzyme MAO-B in the spinal fluid after 20 CES treatments. (3) Patients with treatment-resistant depression have shown significant (P < 0.0089) elevations in plasma serotonin. (4) Increases in cerebrospinal fluid levels of [beta]-endorphins up to 219%, plasma endorphins endorphins (ĕndôr`fĭnz), neurotransmitters found in the brain that have pain-relieving properties similar to morphine. There are three major types of endorphins: beta endorpins, found primarily in the pituitary gland; and enkephalins and up to 98%, and cerebrospinal fluid serotonin up to 200% have been demonstrated in normal volunteers receiving 20 minutes of CES. (5) A recent annotated bibliography of CES by Kirsch (6) details 126 human and 29 experimental animal studies of CES conducted over the past 40 years. More than half the studies cited are from the peer-reviewed literature. The majority of the studies were double-blinded and conducted at major American universities. In aggregate, there were 6,007 patients treated under varying research conditions, with 4,541 actually receiving CES treatment. One hundred twelve (89%) of the studies reported positive outcomes. Seventeen studies followed up the patients to assess any continued results after 1 week to 2 years, and all the patients showed at least some residual effect after one or a series of treatments.

Medications prescribed to relieve major depression. Classes of antidepressants include selective serotonin reuptake inhibitors (fluoxetine/Prozac, sertraline/Zoloft), tricyclics (amitriptyline/ Elavil), MAOIs (phenelzine/Nardil), and heterocyclics and other medications in today's Physician's Desk Reference Physician's Desk Reference (PDR),

The patient safety movement and burgeoning Internet resources are working to increase the number of patients more actively involved in their own care.

CES is not a miraculous modality, but it's definitely worth a try.
