Dan Aykroyd Tourettes Aspergers
In an NPR radio interview with Terry Gross in 2004, Aykroyd talked about his childhood struggle with neurological disorders Tourette and Asperger's Syndrome.
During the half-hour long interview, Gross asks the star whether he was diagnosed with schizophrenia aged 12 because he heard voices in his head.
It was his parents (his father was a civil engineer, his mother a secretary) who started Aykroyd on the acting path by enrolling him at an improvisational class.
They didn't particularly want him to be an actor, they just thought it would help calm their hyperactive son - he had been expelled from two schools for acting up and a psychiatrist had diagnosed Tourettes and mild Asperger's syndrome, because Aykroyd had a few tics and had shown signs of obsessive compulsive disorder.
