"Mental that one, I'm telling you."
Ronald Weasley giving his considered view of Hermione Granger.[src]

Insanity, also known as madness, is a general term for certain abnormal behavioural patterns, typically associated with those suffering from mental illness.[1] Those suffering from insanity often cannot interact with normal society, and frequently require long-term treatment in a medical facility such as St Mungo's Hospital for Magical Maladies and Injuries. Prolonged exposure to certain curses, such as the Cruciatus Curse or the Imperius Curse, may cause this condition. It can also be inflicted by certain types of potions, either temporarily or permanently, such as the Drink of Despair[2] and possibly Essence of Insanity. Listening to Fwooper song for a sufficiently long period can also cause this condition.[3] Shock Spells may be a treatment for this condition.

In 1991, as Vernon Dursley wildly drove the Dursley family and Harry Potter to various locations in the hope of shaking off following wizards, Dudley Dursley ventured the suggestion that he had gone mad.[4]

In his earlier years at Hogwarts School of Witchcraft and Wizardry, Ronald Weasley, particularly in the early stages of their association, often claimed that Hermione Granger was insane because she was clever, read excessively and for pleasure, and retained information which was never of adequate interest for him to notice.

Starting in the summer of 1995, the Daily Prophet, under pressure from the British Ministry of Magic, ran a smear campaign claiming, among other things, that Harry Potter's assertion that Lord Voldemort had returned was a sign that he had gone insane, which only ended when Voldemort's return was proven following the Battle of the Department of Mysteries. Albus Dumbledore, who was also a prime factor in an attempt to spread Harry's claim, was also considered insane for the duration. When Harry gave an interview to Rita Skeeter regarding these events on Valentine's Day 1996, he wondered how people would react to it, suspecting that for many people it would simply confirm that he was completely insane, "not least because his story would be appearing alongside utter rubbish about Crumple-Horned Snorkacks."[5]

Peeves made this claim of Remus Lupin with a tune to match. "Lupin! Loony, loony, Lupin!"
