tDCS technologies are the buzz word in the world of neuroscience. Positive reviews from the medical community, as well as users around the globe, have created a huge demand for tDCS devices in the market.
Transcranial direct current stimulation helps in modulating neural circuits. In other words, changes happen in the neuron’s threshold for creating electrical impulses. Stimulating different neural pathways has been known to effectively treat various neurological and mental health disorders like depression, anxiety, schizophrenia, Parkinson’s, Alzheimer’s, etc.
Additionally, there have been pieces of evidence to support the effectiveness of tDCS devices in cognitive enhancement as well.
Criteria for choosing tDCS devices
With a market that is flooded with multiple brands of tDCS devices, choosing a reliable one can often be overwhelming. Various factors like the stimulator type, accessories provided in the kit, FDA approval, current and voltage boosting systems, cost, customer reviews, etc are important to consider.
The Fisher Wallace Stimulator, Brain Stimulator v3.0, Apex Type A 18V, Activadose II, Caputron Activadose II tDCS Starter Kit, Soterix, Focus V3, Halo Sport and the Brain Driver v2 are some trending brand names available in the market.
All tDCS devices work on the principle of passing a small current through the brain tissue. The current is passed using electrodes which are placed on the scalp at suggested positions.
Considering the customer reviews before purchasing a device is highly recommended. The Brain Driver review for example, is significantly positive which can be attributed to its convenient features, ease of use, affordable prices as well as prompt customer service.
The technology and science behind tDCS devices
As mentioned earlier, the tDCS devices work by passing small currents through the brain tissue. The current amount is very small, sufficient only to excite the nerve cells and keep them in an excitable state to fire on receipt of the stimulus. The current hence passed also stimulates the production of hormones like dopamine and serotonin (mood enhancers).
So what do you get when you purchase a complete tDCS kit?
Most brands offer a complete package that contains a set of two sponges, electrodes, and a headband along with the stimulator device. You can manually set the time as well as the current level (by choosing from the 4 available levels).
Present-day tDCS devices are convenient for self-use within home settings. However, it is advisable to consult your healthcare provider (to check for various underlying health issues) before starting a brain zapping course.
Applications for mental health issues
Brain health issues have been a serious concern in the last few decades. While conventional drugs like antidepressants have been widely accepted and used, their side effects and limitations cannot be overlooked.
tDCS devices have gone through multiple clinical trials to show that the technology is safe to use with negligible side effects. Treatment of mental health concerns like depression, anxiety, PTSD, hyperactivity, insomnia, memory issues, etc can easily be managed using the tDCS devices.
Growing mental health issues, the need for new treatment lines, large scale approval from the user groups and positive medical trials are the reason for the huge market success of tDCS devices.
I am interested in all things technology, especially automation, robotics and tech that helps change how society will live in the future.
