tDCS treatment

What tDCS is

tDCS delivers a low-intensity continuous electrical current through electrodes placed on the scalp. The current does not trigger neuronal firing: it gently modulates the excitability of specific brain regions, increasing or reducing it depending on electrode polarity. It is non-invasive — no surgery, anaesthesia or needles — and generally well tolerated.

The HDCstim device

Mind Health distributes Newronika's HDCstim system in Brazil, a medical-grade direct-current stimulator. For therapeutic use, the current is up to 2 mA and sessions last about 20 minutes — higher currents or longer times are reserved for research contexts.

Most available clinical studies used research stimulators from other brands; the evidence is extrapolated by analogy, and no result should be attributed specifically to HDCstim.

Safety and tolerability

In the reviewed clinical literature (more than 1,300 individuals), no permanent or serious side effects were reported. The effects described are mild and transient — such as tingling, itching or redness at the electrode site and, less frequently, mild headache or fatigue.

There are rare signals to consider in clinical assessment, such as hypomania in people with bipolar disorder and rare skin reactions. Indication and contraindications must be assessed by a healthcare professional.
