Is tdcs a scam?

No. Tdcs is a safe and non-invasive neuromodulation technology, which regulates brain function by transmitting weak direct current on the scalp surface. Foreign studies show that tDCS can improve the clinical symptoms of schizophrenia, such as cognitive defects, depression, lack of pleasure, loneliness, laziness, etc., and it is not a scam. The project testing is in progress in China.
