 Hysteria ... Salvador Dalí  
In 1980 at age 76, Dalí's health took a catastrophic turn.
His right hand trembled terribly, with Parkinson-like symptoms.
His near-senile wife, Gala Dalí, allegedly had been dosing him with a dangerous cocktail of unprescribed medicine that damaged his nervous system, thus causing an untimely end to his artistic capacity.
In 1982, King Juan Carlos bestowed on Dalí the title of "Marqués de Dalí de Púbol" ("Marquis of Dalí de Púbol") in the nobility of Spain, hereby referring to Púbol, the place where he lived.
The title was in first instance hereditary, but on request of Dalí changed to life only in 1983.
To show his gratitude for this, Dalí later gave the king a drawing ("Head of Europa", which would turn out to be Dalí's final drawing) after the king visited him on his deathbed.
Gala died on June 10, 1982, at the age of 87.
After Gala's death, Dalí lost much of his will to live.
He deliberately dehydrated himself, possibly as a suicide attempt, with claims stating he had tried to put himself into a state of suspended animation as he had read that some microorganisms could do.
He moved from Figueres to the castle in Púbol, which he had bought for Gala and had been the site of her death.
In 1984, a fire broke out in his bedroom under unclear circumstances.
It was possibly a suicide attempt by Dalí, or possibly simple negligence by his staff.
Dalí was rescued by friend and collaborator Robert Descharnes and returned to Figueres, where a group of his friends, patrons, and fellow artists saw to it that he was comfortable living in his Theater-Museum in his final years.
There have been allegations that Dalí was forced by his guardians to sign blank canvases that would later, even after his death, be used in forgeries and sold as originals.
As a result, art dealers tend to be wary of late works attributed to Dalí.
In November 1988, Dalí entered the hospital with heart failure; a pacemaker had already been implanted previously.
On December 5, 1988, he was visited by King Juan Carlos, who confessed that he had always been a serious devotee of Dalí.
On January 23, 1989, while his favorite record of "Tristan and Isolde" played, he died of heart failure at Figueres at the age of 84.
He is buried in the crypt of his Teatro Museo in Figueres.
The location is across the street from the church of "Sant Pere", where he had his baptism, first communion, and funeral, and is only three blocks from the house where he was born.
The Gala-Salvador Dalí Foundation currently serves as his official estate.
The US copyright representative for the Gala-Salvador Dalí Foundation is the Artists Rights Society.
In 2002, the Society made the news when they asked Google to remove a customized version of its logo put up to commemorate Dalí, alleging that portions of specific artworks under their protection had been used without permission.
Google complied with the request, but denied that there was any copyright violation.

In 1999, Laurie Winn Carlson offered an alternative medical theory, that those afflicted in Salem who claimed to have been bewitched, suffered from encephalitis lethargica, a disease whose symptoms match some of what was reported in Salem and could have been spread by birds and other animals.
