Since most of the ways we diagnose autism are based on behavior, we can't rely on biological, structural, or chemical findings to determine if a treatment is working. We primarily measure success based on a patient's change, or lack thereof, in behavior.

The behavioral changes produced by the few effective treatments make life in social settings (including the home) possible, but we have no idea whether they have any effect on the underlying cause (or causes) of autism or whether they even make severely affected patients feel better.

One method intended to help, "facilitated communication," is based on the idea that a sensitive facilitator will hold the hand of a patient over a kind of Ouija board. She will then help the patient respond to questions by sensing his intention and helping guide his hand to spell out answers. Rigorous studies have shown that the spelled-out answers come from the unconscious (or, worse, the conscious) mind of the facilitator. Nonetheless, the practice is still in use, and I know parents who are utterly convinced that it is valid and useful. Frankly, something important did happen when facilitated communication was introduced to my patients: They improved, they brightened, they became more social and more interactive, and they seemed, somehow, happier, even though facilitated communication didn't actually translate their thoughts into words. I'll come back to "why" in a minute.

Children’s Hospital & Research Center Oakland scientist and pediatric emergency medicine physician, Claudia Morris, MD says she has identified a syndrome which combines apraxia (a speech disorder) with symptoms often associated with autism. Many of these symptoms are precisely the ones that are pointed to by those whose children appear to benefit from biomedical treatments -- specifically Gluten and Casein-free diets and vitamin supplements.

The data clearly demonstrated a common cluster of allergy, apraxia and malabsorption, along with low muscle tone, poor coordination and sensory integration abnormalities. In addition, Dr. Morris was able to gather laboratory analyses in 26 of the children, which revealed low carnitine levels, abnormal celiac panels, gluten sensitivity, and vitamin D deficiency among others. All children genetically screened carried an HLA gene associated with gluten sensitivity and celiac disease.

Most significantly, the data indicate that the neurologic dysfunction represented in the syndrome overlaps the symptoms of vitamin E deficiency. While low vitamin E bioavailability may occur due to a variety of different causes, neurological consequences are similar, regardless of the initiating trigger. The study suggests that vitamin E could be used as a safe nutritional intervention that may benefit some children. Growing evidence support the benefits of omega 3 fatty acid supplementation in a number of neurodevelopmental disorders.

the brains of people with autism are structurally normal but dysregulated, meaning symptoms of the disorder might be reversible.

autism is a developmental disorder caused by impaired regulation of the locus coeruleus, a bundle of neurons in the brain stem that processes sensory signals from all areas of the body.

The new theory stems from decades of anecdotal observations that some autistic children seem to improve when they have a fever, only to regress when the fever ebbs.

A study published this week by Patricia Howlin of King’s College, London, reinforces this point. It suggests that as many as 30% of autistic people have some sort of savant-like capability in areas such as calculation or music.

Francesca Happé of King’s College, London, is one of them. As she observes, obsessional interests and repetitive behaviours would allow someone to practice, albeit inadvertently, whichever skill they were obsessed by. Malcolm Gladwell, in a book called “Outliers” which collated research done on outstanding people, suggested that anyone could become an expert in anything by practising for 10,000 hours. It would not be hard for an autistic individual to clock up that level of practice for the sort of skills, such as mathematical puzzles, that many neurotypicals would rapidly give up on.

Simon Baron-Cohen, a doyen of the field who works at Cambridge University, draws similar conclusions. He suggests the secret of becoming a savant is “hyper-systematising and hyper-attention to detail”. But he adds sensory hypersensitivity to the list. His team have shown one example of this using what is known as the Freiburg visual acuity and contrast test, which asks people to identify the gap in a letter “c” presented in four different orientations. Those on the autistic spectrum do significantly better at this than do neurotypicals. That might help explain Dr Happé’s observations about coins and raindrops.
