Has anyone ever done electroconvulsive therapy and retained memory?

Effective treatment. Electroconvulsive therapy (ECT) is administered to about 100, 000 people a year. It has been shown in many (but not all) studies to be an effective treatment for severe depression, acute mania, and some schizophrenic symptoms. It is also used with some suicidal patients who would like a quicker effect than is possible with some medications. Memory effects are short-term and very mild. It is safe.
