Prescription-Strength Technology

Manufactured by Fisher Wallace Laboratories, Circadia® uses precisely the same technology as the Fisher Wallace Stimulator® and works by comfortably stimulating the brain to produce serotonin and melatonin while lowering cortisol and modulating the default mode network. The majority of users experience results within the first two weeks of daily use (20 minutes, once or twice a day)Circadia® is strictly intended to help manage stress and sleep.

 

OUR HISTORY

Fisher Wallace Laboratories was founded in 2006 when entrepreneur Charles Fisher and addiction researcher Martin Wallace, PhD, acquired the patents to the Liss Cranial Stimulator®, a medical device invented by electrical engineers who worked in partnership with physicians and research scientists that received FDA-Clearance in 1990. The device was renamed the Fisher Wallace Stimulator® and by 2010, several hundred psychiatrists were finding the device to be effective with thousands of treatment-resistant patients. Additional clinical research was launched at Mount Sinai Beth Israel Hospital and Phoenix House, with a landmark study published in 2015. In 2017, after 30,000 patients had been treated with the device, the company launched its first wellness brand, Circadia®, that cloned the technology of the Fisher Wallace Stimulator® and was intended to manage stress and sleep, without a prescription.

Powerful Relief,
Yet Comfortable

Circadia® uses prescription-strength brain stimulation technology that is comfortable and easy-to-use. Users typically feel more relaxed within the first 10 minutes of stimulation.

Safer Than
Drug Therapy

Less than 1% of patients experience side effects, all minor, from using Circadia®. By comparison, more than 20% of patients experience side effects from using zolpidem, a common sleep medication.1

Is Transcranial Electrical Stimulation (TCES) a safe intervention for children with Cerebral Palsy?

Alon, G, Syron S, Smith G
Neurorehabil Neural Repair June 1998 vol. 12 no. 2 65-71

We tested the safety of transcranial electrical stimulation (TCES) applied to seven children (age range 2.5 to 7.5 years) with a confirmed diagnosis of cerebral palsy (CP). Adverse responses were assessed by negative changes in the gross motor function measure test (GMFM), the popliteal angle, and the occurrence of any undesired systemic responses such as seizure, nausea, vomiting, or sleep disruption. The tests first were given before the commencement of a physical therapy exercise (PTE) program combined with a home program of TCES. The tests were repeated after 8 weeks of PTE + TCES and once again after an additional 8 weeks of PT + TCES. One of the 8- week periods involved placebo stimulation in a double-blind design. Stimulator amplitude was 0.5 mA of peak current, phase charge was 0.0166 C, and the averaged RMS current was 249 microamperes. This level was below threshold of sensory nerve excitation, and the child did not perceive the stimulation. Electrodes were placed over the right and left temporal areas of the skull. The stimulation was applied by the parents for 10 minutes, twice a day, 7 days each week. The total goal GMFM scores were greater after both active and placebo stimulation. The popliteal angle improved irrespective of the stimulation intervention. No adverse systemic responses were reported. These results support the hypothesis that TCES as used in this study is a safe procedure.

Cognitive, mood, and electroencephalographic effects of noninvasive cortical stimulation with weak electrical currents.

Tadini L, El-Nazer R, Brunoni AR, Williams J, Carvas M, Boggio P, Priori A, Pascual-Leone A, Fregni F.
J ECT. 2011 Jun;27(2):134-40. doi: 10.1097/YCT.0b013e3181e631a8. (PubMed link)

OBJECTIVES:The use of noninvasive cortical electrical stimulation with weak currents has significantly increased in basic and clinical human studies. Initial, preliminary studies with this technique have shown encouraging results; however, the safety and tolerability of this method of brain stimulation have not been sufficiently explored yet. The purpose of our study was to assess the effects of direct current (DC) and alternating current (AC) stimulation at different intensities in order to measure their effects on cognition, mood, and electroencephalogram.
METHODS:Eighty-two healthy, right-handed subjects received active and sham stimulation in a randomized order. We conducted 164 ninety-minute sessions of electrical stimulation in 4 different protocols to assess safety of (1) anodal DC of the dorsolateral prefrontal cortex (DLPFC); (2) cathodal DC of the DLPFC; (3) intermittent anodal DC of the DLPFC and; (4) AC on the zygomatic process. We used weak currents of 1 to 2 mA (for DC experiments) or 0.1 to 0.2 mA (for AC experiment).
RESULTS: We found no significant changes in electroencephalogram, cognition, mood, and pain between groups and a low prevalence of mild adverse effects (0.11% and 0.08% in the active and sham stimulation groups, respectively), mainly, sleepiness and mild headache that were equally distributed between groups.
CONCLUSIONS: Here, we show no neurophysiological or behavioral signs that transcranial DC stimulation or AC stimulation with weak currents induce deleterious changes when comparing active and sham groups. This study provides therefore additional information for researchers and ethics committees, adding important results to the safety pool of studies assessing the effects of cortical stimulation using weak electrical currents. Further studies in patients with neuropsychiatric disorders are warranted.

Frequently Asked Questions

Is there anyone who should not use CIRCADIA®?

The only patients who are not qualified to use our device are those with implanted medical devices, such as an implanted nerve stimulator or pacemaker, as CIRCADIA® may interfere with the functioning of such devices.

The device is contraindicated for use on the body in patients who have demand or sensing type cardiac pacemakers. This device should not be used around the Carotid sinus. Patients with known or suspected heart disease should not be stimulated. Patients who react poorly to the idea of electrical stimulation of any kind should not use this device. Patients whose skin is irritated around either electrode site should discontinue use of this device.

Are there any potential side effects of using CIRCADIA®?

Less than 1% of CIRCADIA® users may experience a temporary headache, dizziness or skin irritation at the electrode sites. CIRCADIA® may be used safely in conjunction with any medication.

How does CIRCADIA® work?

CIRCADIA® works by comfortably stimulating the brain to produce serotonin, endorphins and melatonin while lowering the stress hormone cortisol, as demonstrated in published studies. A 60-subject study published in 1999 also demonstrated improved focus and concentration after low dose alternating current stimulation, and a 2012 study determined that low dose alternating current dampens the brain's Default Mode Network (DMN) which is active during periods of stress. Access our research Dropbox.

What's the difference between CIRCADIA® and the Fisher Wallace Stimulator®?

CIRCADIA® and the Fisher Wallace Stimulator® are identical technologically, but CIRCADIA® is defined as a general wellness device because it is intended to help people manage stress and sleep. CIRCADIA® is not intended to treat medical conditions. The Fisher Wallace Stimulator® is defined as a medical device because it is indicated to treat anxiety, insomnia and depression.

What does the stimulation feel like?

Most users will not feel the stimulation, while some may feel a mild tingling at the sponge electrode sites. Users typically feel more relaxed after the first 10 minutes of stimulation, as a result of neurotransmitter production.

CIRCADIA® is powered by two AA batteries which typically last for six months of daily usage.

Based on our scientific, clinical and market data, CIRCADIA® will help approximately 80% of daily users. Consistently using CIRCADIA® on a daily basis for the first 30 days is important to experience results; once you experience long-lasting benefit, CIRCADIA® may be used on a maintenance basis (3-4 times per week) or on an as-needed basis.

Based on over 10 years of patient monitoring and reporting associated with the Fisher Wallace Stimulator® (from which CIRCADIA® is technologically cloned), there are no long-term negative effects of using our technology.

We recommend using CIRCADIA® every day for the first 30 days. You may then continue on a daily basis, maintenance basis (3-4 times per week) or on an as-needed basis. There are no negative effects associated with abruptly ceasing its use.

Most users will feel more relaxed after 10 minutes of stimulation and will experience durable results after the first two weeks of daily use.
