Device used to perform CES

Cranial electrotherapy stimulation (CES) is a form of neurostimulation that delivers a small, pulsed, alternating current via electrodes on the head. [1] CES is used with the intention of treating a variety of conditions such as anxiety, depression and insomnia. [1] CES has been suggested as a possible treatment for headaches, fibromyalgia, smoking cessation, and opiate withdrawal, [1] but there is little evidence of effectiveness for many of these conditions and the evidence for use in acute depression is not sufficient to justify it. [2]

Medical uses

A 2014 Cochrane review found insufficient evidence to determine whether or not CES with alternating current is safe and effective for treating depression. [2] The FDA came to the same conclusion in December 2019. [3]

A 2018 systematic review found that evidence is insufficient that CES has clinically important effects on fibromyalgia, headache, neuromusculoskeletal pain, degenerative joint pain, depression, or insomnia; low-strength evidence suggests modest benefit in patients with anxiety and depression. [4]

Description

Electrodes are placed on the earlobes, maxilla-occipital junction, mastoid processes or temples. [5]

Despite the long history of CES, its underlying principles and mechanisms are still not clear. [1]

CES stimulation of 1 mA (milliampere) has shown to reach the thalamic area at a radius of 13.30 mm. CES has shown to induce changes in the electroencephalogram, increasing alpha relative power and decreasing relative power in delta and beta frequencies. [5] [ relevant? ]

CES has also shown to reach cortical and subcortical areas of the brain, [6] in electromagnetic tomography and functional MRI studies. [5] CES treatments have been found to induce changes in neurohormones and neurotransmitters that have been implicated in psychiatric disorders: substantial increases in beta endorphins, adrenocorticotrophic hormone, and serotonin; moderate increases in melatonin [7] [ better source needed ] and norepinephrine, modest or unquantified increases in cholinesterase, gamma-aminobutyric acid, and dehydroepiandrosterone, and moderate reductions in cortisol. [5]

History

Low intensity electrical stimulation is believed to have originated in the studies of galvanic currents in humans and animals as conducted by Giovanni Aldini, Alessandro Volta and others in the 18th century. Aldini had experimented with galvanic head current as early as 1794 (upon himself) and reported the successful treatment of patients with melancholia using direct low-intensity currents in 1804. [8]

CES was initially studied for insomnia and called electrosleep therapy; [9] it is also known as cranial-electro stimulation [10] and transcranial electrotherapy. [11]

Due to the rise of pharmaceutical treatments for depression, anxiety and insomnia, such as Prozac in the 1980s and Ambien in the 1990s, CES was not a well-known treatment for doctors and patients. During the mid-2000s, the combination of pharmaceutical brands becoming generic and Internet advertising caused CES devices to gain popularity. In 2011, the devices received media attention from the Wall Street Journal. [12]

Regulation

In the United States, CES technology is classified by the Food and Drug Administration (FDA) as a Class III medical device and must be dispensed by or on the order of a licensed healthcare practitioner, i.e., a physician, psychiatrist, nurse practitioner, psychologist, physician assistant, or occupational therapist who has an appropriate electrotherapy license, dependent upon state regulations. [13] The United States requires a prescription for CES devices from a licensed healthcare practitioner. The FDA says that there are 11 CES devices cleared for marketing in the United States. [14] [15]

In June 2014, the FDA announced that it "has determined that there is sufficient information to establish special controls, and that these special controls, together with general controls, will provide a reasonable assurance of safety and effectiveness for CES devices. In this action, FDA is withdrawing the proposed rule and proposed order to call for PMAs [premarket approvals] for CES devices. FDA plans to issue a proposed order in the future for the reclassification of the CES device into class II." [16]

In December 2019, the FDA announced that there is no valid evidence for CES as a treatment for depression, and request new trials to be made. "FDA concluded that the four studies published after January 1, 2016, through November 1, 2019, did not contribute sufficient information in the form of valid scientific evidence to demonstrate that the subjects met the criteria for any recognized depressive disorder, as defined in DSM-5" [3]

Electroconvulsive therapy (ECT) or electroshock therapy (EST) is a psychiatric treatment where a generalized seizure is electrically induced to manage refractory mental disorders. Typically, 70 to 120 volts are applied externally to the patient's head, resulting in approximately 800 milliamperes of direct current passing between the electrodes, for a duration of 100 milliseconds to 6 seconds, either from temple to temple or from front to back of one side of the head. However, only about 1% of the electrical current crosses the bony skull into the brain because skull impedance is about 100 times higher than skin impedance.

Transcranial magnetic stimulation (TMS) is a noninvasive form of brain stimulation in which a changing magnetic field is used to induce an electric current at a specific area of the brain through electromagnetic induction. An electric pulse generator, or stimulator, is connected to a magnetic coil connected to the scalp. The stimulator generates a changing electric current within the coil which creates a varying magnetic field, inducing a current within a region in the brain itself.

<span class="mw-page-title-main">Transcutaneous electrical nerve stimulation</span> Therapeutic technique

Transcutaneous electrical nerve stimulation is the use of electric current produced by a device to stimulate the nerves for therapeutic purposes. TENS, by definition, covers the complete range of transcutaneously applied currents used for nerve excitation although the term is often used with a more restrictive intent, namely to describe the kind of pulses produced by portable stimulators used to reduce pain. The unit is usually connected to the skin using two or more electrodes which are typically conductive gel pads. A typical battery-operated TENS unit is able to modulate pulse width, frequency, and intensity. Generally, TENS is applied at high frequency (>50 Hz) with an intensity below motor contraction or low frequency (<10 Hz) with an intensity that produces motor contraction. More recently, many TENS units use a mixed frequency mode which alleviates tolerance to repeated use. Intensity of stimulation should be strong but comfortable with greater intensities, regardless of frequency, producing the greatest analgesia. While the use of TENS has proved effective in clinical studies, there is controversy over which conditions the device should be used to treat.

Neurohacking is a subclass of biohacking, focused specifically on the brain. Neurohackers seek to better themselves or others by “hacking the brain” to improve reflexes, learn faster, or treat psychological disorders. The modern neurohacking movement has been around since the 1980s. However, herbal supplements have been used to increase brain function for hundreds of years. After a brief period marked by a lack of research in the area, neurohacking started regaining interest in the early 2000s. Currently, most neurohacking is performed via do-it-yourself (DIY) methods by in-home users.

Neuromodulation is "the alteration of nerve activity through targeted delivery of a stimulus, such as electrical stimulation or chemical agents, to specific neurological sites in the body". It is carried out to normalize – or modulate – nervous tissue function. Neuromodulation is an evolving therapy that can involve a range of electromagnetic stimuli such as a magnetic field (rTMS), an electric current, or a drug instilled directly in the subdural space. Emerging applications involve targeted introduction of genes or gene regulators and light (optogenetics), and by 2014, these had been at minimum demonstrated in mammalian models, or first-in-human data had been acquired. The most clinical experience has been with electrical stimulation.

Techniques such as transcranial magnetic stimulation (TMS) or transcranial direct current stimulation (tDCS) can be used.
