The concept of electroconvulsive therapy is a treatment method that applies a low-frequency electric current to the patient’s head, causing the patient to lose consciousness for an instant and short period of time, resulting in general rigidity, convulsions, and a transient loss of consciousness, and slowly waking up after a few minutes. This treatment can be applied to treat clinical patients in psychiatry, such as patients with extreme negativity, depression and mute, who can be treated with electroconvulsive shock, and patients with extreme excitement and extreme mania, who can also be treated with electroconvulsive shock. After several treatments of electroconvulsive shock, certain patients will play a significant role in improving clinical symptoms and outcome. For example, depressed patients who insist on committing suicide will also disappear and have their suicidal thoughts relieved after electroconvulsive treatment, and extremely depressed patients will also have some improvement through electroconvulsive treatment.
