Singer Susan Boyle has revealed that she has been diagnosed with Asperger’s Syndrome – after years of believing she had sustained brain damage at birth.

The former Britain’s Got Talent finalist – who has become a global superstar after finishing second in the 2009 series – told the Observer that she had been given the wrong diagnosis as a child.

“I was told I had brain damage,” explained Susan, who has previously revealed she suffers from learning difficulties.

“I always knew it was an unfair label. Now I have a clearer understanding of what’s wrong and I feel relieved and a bit more relaxed about myself.”

She added that the condition “would not make any difference to my life,” saying: “It’s just a condition that I have to live with and work through.

“I think people will treat me better because they will have a much greater understanding of who I am and why I do the things I do.”

Asperger’s Syndrome is a form of autism whose sufferers have difficulty dealing with social situations and other relationships.

Susan admitted that she was told she had the condition after seeing a Scottish specialist – who also confirmed her IQ was ‘above average’.
