Jill Price (née Rosenberg, born December 1965 in New York City) is able to recite details of all the days of her life since she was fourteen years old. She can recall various obscure moments of her life in high detail Price's condition is called hyperthymestic syndrome, characterized by a superior autobiographical memory. She appears to have enlarged parts of her brain associated with obsessive compulsive disorder (OCD). The first report on the study of her brain was published in 2006.She has written a book called The Woman Who Can't Forget: The Extraordinary Story of Living with the Most Remarkable Memory Known to Science...A Memoir (ISBN 1416561765), explaining her life with the condition.
The claim of Price's perfect memory has been contested as manifesting merely as an obsessive compulsion with herself and her own life and past, and she seems not to have any extraordinary ability to memorize things not related to them, and shows no signs of above-normal ability to memorize new data not related to her own life.
