Enhancement of cognitive insight and higher-order neurocognitive function with tDCS

The authors observed significant trends that tDCS ameliorated the severity of total and general psychopathology as measured by the Positive and Negative Syndrome Scale. No significant effects were observed for other psychopathological symptoms and psychosocial functioning. Cognitive insight as measured by the Beck Cognitive Insight Scale (BCIS) was rapidly enhanced by 10-session tDCS (F = 10.80, Cohen’s d = 0.44, p = 0.002) but the beneficial effect became borderline significant 1 month after stimulation.

I don’t have access, but it sounds as if the effect is relatively short lived if you don’t keep doing it. However, tDCS headsets aren’t expensive the way rTMS machines are (millions) so potentially an in office or home therapy at some unknown date in the future. If replicated, obviously.
