A woman has lost her memory, prompting her husband to write a book detailing their love story, "I know I love you."

Steve Corto published the book, which tells the story of his love with his wife, Camry, the memory, according to the newspaper "Sky News".

Camry suffered a stroke during her birth and went into a 33-week absence, which eventually led to her total memory loss.

Doctors diagnosed Camry with pre-eclampsia, a condition that causes high blood pressure and reduces its flow to the brain, leading to a stroke that affects memory.
