Which of the following therapy is given only when drugs are not effective in controlling the symptoms of the patient?

Electro convulsive Therapy

People with mental problems are sometimes given electric shocks. Electro-convulsive Therapy (ECT) is another form of biomedical therapy. Mild electric shock is given via electrodes to the brain of the patient to induce convulsions. The shock is given by the psychiatrist only when it is necessary for the improvement of the patient. ECT is not a routine treatment and is given only when drugs are not effective in controlling the symptoms of the patient.
