Final answer:
The false statement about ECT is that it is typically used as a first-line treatment for depression. It is instead used when other treatments have failed or in severe cases that require an immediate response.
Step-by-step explanation:
While ECT is a safe and effective treatment for severe depression, and memory loss is indeed a common side effect, ECT is generally considered only after other treatments have failed or when a rapid response is necessary due to the severity of the patient's condition. It is not the first treatment option that is chosen; initial treatments usually involve antidepressant medications and psychotherapy.
