Kelly Preston discussed the circumstances surrounding her autistic 16-year-old son Jett Travolta's death in 2009 on medical chat show 'The Doctors'. 

The 'What a Girl Wants' actress and her Oscar nominated husband John Travolta have always maintained that their youngest son suffered with mental health problems which caused him to have a seizure and subsequently suffer a serious head injury after hitting his head on the bathtub during a family holiday to The Bahamas. When explaining the incident, Kelly said: 'He was autistic. He had seizures, and when he was very young, he had Kawasaki syndrome.' Kawasaki Syndrome is rare autoimmune disease with an unknown cause which causes blood vessels to become inflamed and can often be fatal, and Kelly believes that it was one of the factors that contributed to Jett developing autism. Other causes she described were complications in labour, taking antibiotics while breast feeding which led to her son developing thrush and chemicals and pesticides in food and cleaning products. 

The actress also claimed that medication taken to stabilise Jett's autism never worked but a healthy lifestyle looked to be a likely cure. 'We would try all different things, and I felt when we were able to keep certain things at a bare minimum and do as healthy as possible, he did so much better', she said. 'He was coming out of the autism.'
