tDCS (Transcranial Direct Current Stimulation) is a contemporary form of neurostimulation
(or neuromodulation) that delivers a constant low current to specific areas of the brain.
How does it work exactly and what are they for?
By applying a positive or negative current through electrodes to one area to help with the depolarization or hyperpolarization of neurons, in other words, increasing or lowering neurons’ threshold to send electrical pulses.
Originally, tDCS was developed and refined to aid patients with brain injuries or with neurological disorders, however, several scientific studies have demonstrated the effectiveness of tDCS in cognitive enhancement for the general population.
In layman’s terms, these are DYI devices for depression and anxiety treatment at home, and they also help treating sleeping disorders (I personally experienced deeper sleep sessions after using the FDA approved ActivaDose tDCS Starter Kit).
According to Google Trends, Denmark, USA, and Australia are the top three countries using tDCS, today. Denmark has admitted tDCS to public, private, and education hospitals, Australia has promoted tDCS as a non-invasive treatment, and the USA has validated tDCS technology on a large scale.
In this cozy safe space of mine, I rank the best tDCS devices to use for your disorders:
The Brain Driver, Muse 2 Headband, Caputron Activadose (scroll down for a special discount code), the Flow tDCS Headset and NeoRhythm by OmniPemt (PEMT technology) based on their features, cost, delivery time, and effectiveness, topped with real-life user reviews.
