Electric shock therapy (also known as brain stimulation therapy) may have a positive effect on improving memory and cognitive function in some cases, but this therapy is usually performed in a strictly controlled medical environment and requires the guidance and supervision of professionals. The intensity, frequency, and application time of the current all need to be precisely evaluated and studied. Current research shows that non-invasive brain stimulation technologies such as transcranial direct current stimulation (tDCS) may help improve cognitive function in some cases, but the effects vary from individual to individual, and more research is needed to verify its long-term effects and safety. If you are interested in trying related therapies, it is best to consult a professional doctor or neuroscience expert rather than perform any form of self-treatment on your own.
