Extreme variance from normal behavioral patterns.
Shock Spells (possibly)
Insanity, also known as madness, is a general term for certain abnormal behavioural patterns, typically associated with those suffering from mental illness. 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 and possibly Essence of Insanity. Listening to Fwooper song for a sufficiently long period can also cause this condition. Shock Spells may be a treatment for this condition.
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 it.
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.
Known insane individuals
- According to Albus Dumbledore, people have been driven to insanity attempting to realise the visions provided by the Mirror of Erised.
- As Uric the Oddball is known to have listened to Fwooper song for several months non-stop, as well as to have engaged in various eccentric behaviours, he was most likely insane. Also the look on his face and his jellyfish-hat lead to this belief.
- Frank and Alice Longbottom were driven insane due to prolonged exposure to the Cruciatus Curse by Bartemius Crouch Jr. and the Lestranges. They were resident permanently in the Janus Thickey Ward of St. Mungo's Hospital for Magical Maladies and Injuries, and no longer seemed to recognise their son.
- An old Muggle tramp Harry Potter saw when shopping with the Dursleys apparently was insane, as he was talking to a person who was not there.
- Bartemius Crouch Sr. became insane after continual usage of the Imperius Curse on him by his own son. When Harry Potter and Viktor Krum found him on the edge of the Forbidden Forest in 1995, he wildly shifted back and forth between coherence and statements to his surroundings, and believed it was several months earlier and he was dictating instructions to his assistant, Percy Weasley.
