Could a gentle zapping of the brain ease MS fatigue and brain fog?

This trial investigates whether a non-invasive technique called transcranial direct current stimulation (tDCS) can help with fatigue, depression, anxiety, and cognitive problems in people with multiple sclerosis (MS). tDCS uses a weak electrical current applied to the scalp to gently stimulate specific brain areas. The study includes 38 adults with relapsing or progressive MS who have had fatigue for at least six months. Each participant will receive both real tDCS and a sham (fake) treatment in a random order, and neither they nor the researchers will know which is which during the trial. The goal is to see if real tDCS reduces fatigue and improves mood and thinking more than the sham treatment.
