This study tested an optimized multichannel tDCS (a non-invasive brain stimulation device) against standard and sham versions in 60 adults with moderate-to-severe major depression. The goal was to see if the new protocol better reduces depressive symptoms and improves memory and …

This completed Phase 1 trial tested transcranial direct current stimulation (tDCS) in 42 adults with obsessive-compulsive disorder (OCD). Participants received 10 sessions of either low-dose, higher-dose, or fake (sham) electrical stimulation over five days. The goal was to see i…

This study tested whether two types of mild electrical brain stimulation (tDCS and tRNS) could improve memory and thinking in 36 people with schizophrenia. Participants received both types of stimulation on different days to compare effects. The goal was to see if these safe, non…

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. Researchers measured changes in …

This study tested whether a gentle electrical current applied to the scalp at 40 Hz can strengthen brain rhythms linked to memory in healthy adults aged 50-80. Thirty participants received the stimulation while performing a working memory task. The goal was to see if this approac…

This study tested whether combining two non-invasive brain stimulation techniques (tACS and iTBS) can enhance gamma brain waves and working memory in 30 healthy adults. The goal is to develop better stimulation protocols that could one day help people with Alzheimer's disease. Pa…
