Electric shock therapy, also known as electroconvulsive therapy (ECT), is a medical treatment that involves the controlled administration of electric currents to the brain with the purpose of inducing a brief seizure. This procedure is primarily used in cases of severe mental illnesses, such as major depressive disorder, bipolar disorder, and certain forms of schizophrenia, when other treatments like medications and psychotherapy have not been effective or when the individual is in a critical condition.
Here's how the process generally works:
Preparation: Before undergoing ECT, the patient undergoes a comprehensive medical evaluation, including physical and mental health assessments, blood tests, and sometimes imaging studies. This helps to ensure that the patient is a suitable candidate for the procedure and that any potential risks are minimized.
Anesthesia and Muscle Relaxation: ECT is performed under general anesthesia to prevent the patient from feeling pain during the procedure. Muscle relaxants are also administered to prevent any convulsions from becoming overly severe and causing injury.
Electrode Placement: Electrodes are placed on specific areas of the patient's scalp to deliver the electric currents to the brain. The placement depends on the specific condition being treated and is usually determined by the treating medical team.
Electric Current Administration: A controlled electric current is then passed through the electrodes, leading to a controlled seizure in the brain. The seizure typically lasts for a short period, usually around 20 to 60 seconds. The exact mechanism by which ECT works is not fully understood, but it is believed to involve alterations in brain chemistry and neurotransmitter activity.
Recovery: After the procedure, the patient is closely monitored as they wake up from anesthesia. The effects of the seizure, such as confusion and memory loss (especially for events surrounding the treatment), may occur and are temporary in nature.
Treatment Schedule: ECT is usually administered in a series of sessions over several weeks. The exact number of sessions and their frequency depend on the patient's response to treatment and the severity of their condition. Maintenance ECT sessions might also be recommended to prevent relapse.
It's important to note that ECT has evolved significantly over the years. Modern ECT is carried out with advanced monitoring equipment, anesthesia techniques, and muscle relaxants, which have improved its safety and reduced the risk of adverse effects. However, like any medical procedure, ECT does carry some risks and potential side effects, including memory difficulties, confusion, headaches, and, in rare cases, physical injuries.
While ECT can be an effective treatment for severe mental illnesses, it is typically considered when other treatments have failed, due to the potential side effects and the need for careful consideration of the benefits versus the risks. The decision to undergo ECT is made by a multidisciplinary team of medical professionals, taking into account the patient's individual needs and circumstances.
