Seizures are electrically induced (in anesthetized patients) for therapeutic effect

The statement you provided seems to be referring to a medical procedure known as Electroconvulsive Therapy (ECT). Here's a step-by-step explanation:

1. ECT is a procedure, done under general anesthesia, in which small electric currents are passed through the brain, intentionally triggering a brief seizure.

2. ECT seems to cause changes in brain chemistry that can quickly reverse symptoms of certain mental health conditions.

3. ECT often works when other treatments are unsuccessful and when the full course of treatment is completed, but it may not work for everyone.

4. It is generally used as a last resort for severe depression that has not responded to other treatments.

5. The procedure starts with the patient being put under general anesthesia and a muscle relaxant is given to prevent the body from convulsing.

6. Electrodes are placed on the patient's scalp and a finely controlled electric current is applied. This current causes a brief seizure in the brain.

7. Because the muscles are relaxed, the seizure will usually be limited to slight movement of the hands and feet. The patient is carefully monitored during the treatment.

8. The patient wakes up after about 5 to 10 minutes after the procedure, does not remember the treatment or events surrounding it, and is often confused.

9. Multiple sessions are usually required, often given two to three times a week until the depression improves.

10. ECT can have side effects such as confusion and memory loss. Although these side effects usually improve within a few days after treatment ends, some people can have long-term problems, especially with memory.
