Some sad news over the weekend, the brother of Gabriel García Márquez says the author is suffering from dementia and can no longer write, reports The Guardian.

“He has problems with his memory. Sometimes I cry because I feel like I’m losing him,” Jaime García Márquez said. “Dementia runs in our family and he’s now suffering the ravages prematurely due to the cancer that put him almost on the verge of death. Chemotherapy saved his life, but it also destroyed many neurons, many defences and cells, and accelerated the process. But he still has the humour, joy and enthusiasm that he has always had.”

The 85-year-old Colombian writer won the Nobel Prize for Literature prize in 1982 and is best known for One Hundred Years of Solitude, Love in the Time of Cholera and Chronicle of a Death Foretold.
