Depression is mainly manifested as persistent and obvious mood depression. In severe cases, there may be negative suicidal behavior, catatonia, and other behaviors. For this type of depression, electroconvulsive therapy is mainly used, mainly through electroconvulsive therapy (ECT) and MECT. Currently, in clinical practice, MECT is mostly used. The difference lies in the treatment method, scope of application, adverse reactions, etc.

1, Electric shock therapy: By using a certain amount of current, it produces a stimulating effect after passing through the brain, causing the patient to have a grand mal seizure, loss of consciousness, and thus achieving the therapeutic purpose;

2, MECT: The spasm caused by the administration of anesthetic, muscle relaxants, and a mild electric current passing through the brain is shorter and easier to control than that of electroconvulsive therapy.

1, Electric shock therapy: For patients with severe depression, such as self-harm, suicidal behavior, catatonia, and those who are ineffective to antidepressants, it should be used with caution;

2, MECT: The scope of application is slightly broader than that of electroconvulsive therapy, and it can be used not only for the treatment of severe depression symptoms but also for patients with somatic diseases who cannot use antidepressants. The contraindications are fewer than those of electroconvulsive therapy and can be used for the elderly or pregnant women.

1, Electric shock therapy: When electricity is applied, it can cause seizures in the human body, which may lead to tongue bite injury, urinary incontinence, dilated pupils, and whole-body muscle tension. Excessive force may lead to joint dislocation and fracture;

2, MECT: Due to the use of muscle relaxants, it can significantly reduce the occurrence of adverse reactions such as joint dislocation and fracture. After anesthesia, there may be adverse reactions such as dizziness, nausea, and vomiting.
