Balthazar's depression is being treated through a procedure in which electrodes are placed on both sides of his head and a brief current is turned on. the current triggers a seizure that lasts about a minute, causing his body to convulse. his treatment is known as:

Electro Convulsive Therapy (ECT)

Electroconvulsive therapy is a procedure, in which brief electric currents are passed through the brain to deliberately trigger a brief seizure. This procedure is performed under general anesthesia and using muscle relaxants to prevent convulsing during the seizure. ECT is mainly used for the treatment of severe, life-threatening depression and severe postnatal depression.
