Electroshock therapy side effects, the exact name of electroshock therapy, should be electroconvulsive therapy. Nowadays, modified electroconvulsive therapy is widely used in clinical practice, which is the treatment based on general anesthesia. This avoids the occurrence of muscle tonic spasm attacks, reduces muscle tonic twitching, causing physical risks, and reduces the pain caused to the patient during treatment. The overall safety of electroconvulsive therapy is guaranteed when it is performed under the precursor of a full assessment of the patient’s physical symptoms. However, adverse effects are inevitable. The more common ones are headache and nausea after treatment, and some patients may experience memory loss for a short period of time. Less common adverse reactions are that a small number of patients may develop complications of cardiovascular disease or adverse effects on breathing. These are fully assessed by healthcare professionals during treatment, and the risk of occurrence is generally not particularly high. Overall, electroconvulsive therapy is prescribed only after a physician has adequately assessed the patient’s physical condition when there is an indication for the treatment and the need to undergo it to minimize the risk of various adverse effects, but there is still a certain amount of risk associated with it.
