Electroconvulsive therapy (ECT) is primarily used to treat severe depression, bipolar disorder, and some forms of schizophrenia, not to improve memory. In fact, ECT can cause short-term memory loss and other cognitive side effects. There is some scientific research on the effects of electrical stimulation on memory, but this usually involves non-invasive brain stimulation techniques such as transcranial direct current stimulation (tDCS) or transcranial magnetic stimulation (TMS), rather than ECT. Research on memory improvement is still exploratory and the effects vary from person to person, so there is no consistent scientific conclusion. If you are interested in non-invasive brain stimulation techniques, you should consult a professional medical practitioner and have them performed in a professionally supervised and research facility. In addition, any form of electrical stimulation has potential risks and should not be performed on your own. For any health-related issues, especially those related to medical treatment, it is recommended to consult a doctor or professional medical staff for the most accurate and personalized advice.
