John Waite investigates why scientists say autism research receives a fraction of the funding invested in other conditions and that as a consequence, there are very few effective interventions to treat the disorder. Meanwhile, parents of autistic children say they face a long wait for treatment provided by their local authority, and have instead turned to unproven methods offered by nutritionists and psychotherapists.
