Researchers at Stanford University have developed an experimental depression treatment called Stanford accelerated intelligent neuromodulation therapy (SAINT), which uses high doses of magnetic brain stimulation to target individual neurocircuitry. In a controlled study, 79% of participants with severe depression experienced remission within days, with the effects lasting for months. The treatment was found to be effective and safe, with only temporary fatigue and headaches as side effects. The study's results suggest that SAINT could be a game-changer in the treatment of depression.
