Perhaps the autopsy will tell. But listening to the official version of events makes one's head spin:
Travolta and Preston said that their son, who appeared confused or unsure of his surroundings in public, had suffered as a young child from Kawasaki disease, brought on by chemicals used to clean their carpets.
They also said that he had a history of seizures which some doctors said could have been the product of brain damage as a result of Kawasaki, a treatable disease characterised by high fever, skin rash and swelling of the lymph nodes that usually affects children under five.
Unusual, to say the least. Members of the Super Adventure Club do not believe in treating mental illness with modern medicine.
