Electroshock devices, commonly known as electroconvulsive therapy (ECT) machines, are medical instruments used to deliver controlled electric currents to the brain. This treatment is primarily used for severe mental health conditions, such as depression and bipolar disorder, when other therapies have failed. The procedure is performed under anesthesia and is closely monitored by healthcare professionals. These devices work by inducing a brief seizure, which can help alleviate symptoms of mental illness. While the exact mechanism is not fully understood, it is believed that the electrical stimulation can reset brain activity and improve mood. Safety measures are in place to minimize risks and side effects.
