This study tested whether an optimized multichannel tDCS device can better ease depression symptoms compared to standard or sham (fake) tDCS. Sixty adults with moderate-to-severe major depression received one of the three tDCS types. Researchers measured mood changes using standa…

This study tested whether repeated electrical brain stimulation could improve mental health and cognitive function in people with multiple sclerosis (MS). Fifty-three adults with MS received either real or fake stimulation in a double-blind setup. The researchers measured quality…

This study tested whether mild electrical stimulation to the brain (tDCS and tRNS) could improve memory and thinking in 36 adults with schizophrenia. Participants completed thinking tasks after receiving different types of stimulation. The goal was to see if these safe, non-invas…

This study tested a painless, mild electrical current applied to the scalp (tDCS) to see if it could reduce obsessive-compulsive symptoms, improve mood, and sharpen thinking. Forty-two adults with OCD were split into three groups to compare real stimulation versus a sham (fake) v…

This study tested whether a gentle electrical current applied to the scalp at a specific frequency (40 Hz) could strengthen brain waves linked to memory in 30 healthy adults aged 50-80. Participants performed a memory task while receiving stimulation to different brain areas. The…

This study tested a new way to stimulate the brain using two techniques—magnetic pulses and mild electrical currents—to boost gamma brain waves, which are linked to memory and often weak in Alzheimer's disease. Thirty healthy adults aged 18–60 completed memory tasks while their b…
