According to a Bahamian police report taken in February after his son Jett's death last year, Travolta acknowledged in his own words that "Jett suffered from a seizure disorder and was autistic." That's a big no-no in Scientology.
The report was obtained by the National Enquirer. Travolta's use of the term "autistic" seems to be a break from church doctrine, which teaches that pyschiatric diagnoses are fake ailments invented by Nazi psychiatrists so they can give people drugs to keep them from realizing their true potential of controlling the physical world with their minds.
Prior to Jett's death, his mother Kelly Preston attributed his problems to a rare disorder called Kawasaki disease and to "environmental toxins" from carpet-cleaners. She claimed that a Scientological detoxification regime had helped to ease his symptoms.
After Jett's death, Scientology representatives denied that the church has taken a stance on autism, saying, "It's medicine. The church deals with the spirit. If people have a medical problem or a physical ailment, they go to a doctor. It's church policy that they do so and they get that addressed." But autism is a psychiatric disorder described in DSM-IV, psychiatry's diagnostic bible. While a case could be made that Travolta was only using the term generally, to describe a disorder with physical roots that he thought could be explained, Scientology-style, by toxins, it's certainly unusual for a high-profile representative of the church to use the word.
