Now Steve Curto, from Michigan in the US, has written a book for her titled But I Know I Love You in which he documents their love story, People reports.

The book comes seven years after Camre lost both her short and long-term memory as a result of a seizure and cataclysmic stroke, which she suffered when she was 33 weeks pregnant and which forced her into labour.

It was only after the first-time-mom awoke from an induced comma that doctors realised her stroke and seizure was as a result of undiagnosed preeclampsia – a pregnancy complication characterised by high blood pressure, Metro reports.

“As soon as she opened her eyes I thought, ‘Camre’s not there.’ She looked at me blankly as if I were a stranger,” Steve said about how he realised his wife had lost her memory.

He then wheeled her to the hospital’s intensive-care unit where their son was being kept and placed her hand on the incubator.

“She patted him distractedly and I realised she had no idea he was her son. It was heart-breaking,” the 38-year-old dad told the Guardian.

Doctors confirmed that Camre had lost all her memory from her childhood, including her wedding proposal and even her pregnancy. She also struggled to make new memories, Steve added.

“But one exhausting day, six weeks after Gavin’s birth, Camre looked at me on the sofa and said, ‘I don’t know who you are but I know I love you.’ ” Steve described this as a turning for both of them and it inspired the title of his book.

With the help of occupational therapy and by continually repeating daily activities Camre has been able to relearn household tasks. But while her short-term memory now extends to three to four days her long-term memory remains wiped out.

But I Know I Love You, which is self-published, was released on the couple’s four-year anniversary and follows the milestones they’ve achieved together with their seven-year-old since his birth, GoodMoringAmerica reports.
