What is electroconvulsive therapy used to treat?

Electroconvulsive therapy (ECT) is primarily used to treat severe depression, especially in cases where other treatments, such as medication and psychotherapy, have not been effective. ECT is particularly effective for individuals who are experiencing major depressive episodes or severe depression with psychotic features. This therapy involves the application of small electric currents to the brain, which can induce a brief seizure. The exact mechanism is not fully understood, but it is believed to lead to changes in brain chemistry that can alleviate depressive symptoms.

For those suffering from severe depression, especially when accompanied by suicidal ideation or when the disorder has become resistant to other therapeutic interventions, ECT can provide rapid improvement. This makes it a valuable treatment option in critical situations where immediate intervention is necessary.
