The Cure is a brain surgery within the Delirium Trilogy that results in the said patient being incapable of love or strong emotions. It is the main combatant against Amor Deliria Nervosa (love) and is mandatory for everyone over eighteen. Those who have received the cure are known as cureds. Those who haven't yet are known as Uncureds.

Sixty-four years before Delirium began, the President of the United States and the Consortium identified love as a disease. A cure was sought and experimented for. Twenty-one years after this first announcement, a cure for love was perfected by Cormac T. Holmes and is eventually made mandatory for everyone over eighteen. Those who refuse the cure are either forced into the procedure or else killed.
The procedure of the cure is usually done in a government building (such as the labs in Portland) or a hospital. Not much is known about the actual procedure itself (although it seems largely implied that a portion of the brain is removed or else cut apart) but what is known is that the person is immobilized with a three-pronged instrument in order to administer the cure. This leaves a trade-mark three pointed scar on the person's neck that every cured has.
The cure has numerous side-effects including the inability to dream and an overall smothering of all emotions. Cureds usually have a filmy, distant look and they feel detached from the rest of the world. Lena Haloway mentions that the cure works differently on everybody and that her cousin, Marcia Tiddle, sometimes cried hysterically for no reason at all after she was cured. Other cureds seem to show sudden emotions without any warning as well.
Although the cure is said to be perfected, it has been shown to have some very unexpected results. There are some adults who are cured and yet still experience strong emotions such as Annabel Haloway. Other people have a total loss of mental function.
While most of those under eighteen are uncured, if they show signs of deliria they are cured regardless of age. This can lead to severe problems as anyone under eighteen who is cured usually has mental disabilities, paralysis, or blindness.
After a person has been cured, they can be married to their pair and no longer have to be segregated from the opposite gender.
- Invalids as members of the resistance have been known to fake the scar of the cure when living in towns and cities.
- Despite the fact that the cure is not safe for those under eighteen, the Deliria-Free America organization has been pushing for everyone to be cured, regardless of age.
