That makes it sound like it has no connection to the other prizes.
It's awarded by the Royal Swedish Academy of Sciences, who also award the Physics and Chemistry prizes. Its winner is announced with the winners of the original prizes. The winner in included in the annual Nobel Prize Award ceremony in Stockholm, and receives a medal, diploma, and monetary grant award document from the King of Sweden at that ceremony. The Nobel Foundation counts it when they say their are 6 prize categories, and includes its winners on their lists of Nobel laureates.
It only differs from say the Chemistry prize in that it was established in memory of Nobel instead of by Nobel and the prize money doesn't come from Nobel's estate.
