A nine-year-old boy who underwent an emergency brain surgery, woke up sans his strong Yorkshire accent, and speaking in the Queen's English.
William’s mum Ruth McCartney-Moore revealed the effect the surgery had on her son.
"We noticed that he had started to elongate his vowels in words like 'bath' which he never did before. He no longer has short vowel sounds - they are all long. It's bizarre,” the Daily Mail quoted Ruth, as saying.
William was admitted in hospital after suffering a fit in March last year.
"It all began with a headache. William said his head really hurt above one eye and he had a high temperature. There was a bug going around school, so my husband and I didn't think it was any more than that. But a few days later he had a massive seizure,” she said.
Doctors discovered he had an abscess on his brain, known as a subdural empyema, which is caused by a rare strain of meningitis, and hence needed a life threatening operation to take away the fluid.
Following the operation William lost the ability to read and write and his memory was also affected.
After being discharged from hospital, William went on a family holiday to Northumberland with his parents and brothers Alex, 16, and Edward, 15.
"William was playing on the beach. He suddenly said, 'Look, I've made a sand castle' but really stretched the vowels out, which made him sound really posh,” Ruth said.
