In 1995 McCrum suffered a massive stroke. The devastating experience and his recovery is chronicled in My Year Off: Recovering Life After a Stroke. He had been married to Sarah Lyall, an American journalist, for only two months and the book includes diary entries made by his wife. He became a patron of the UK charity Different Strokes, which provides information and support for younger stroke survivors.
Sarah Lyall, who writes for The New York Times, lived in London from 1995 to 2013 and was the newspaper's London correspondent for many years. She returned to New York with the couple's daughters in 2013; Lyall and McCrum now have a transatlantic relationship.
