Evidence Basis
Complementary and alternative medicine often lacks support in scientific evidence, so its safety and efficacy are often questionable. Some therapists who advocate CAM may claim to cure many conditions or disabilities that are not diseases and therefore cannot be "cured".
While some experts encourage parents to be open-minded, others argue that treatments and services with no proven efficacy have opportunity costs because they displace the opportunity to participate in efficient treatments and services. According to Scott O. Lilienfeld,
many individuals who spend large amounts of time and money on ineffective treatments may be left with precious little of either. As a result, they may forfeit the opportunity to obtain treatments that could be more helpful. Thus, even ineffective treatments that are by themselves innocuous can indirectly produce negative consequences.
There is often little or no scientific evidence for effectiveness of alternative therapies. It may be difficult to separate the success of a specific treatment from natural development or from the benefits of the individual's positive attitude. Some phenomena to be considered when evaluating studies are the placebo effect, the Hawthorne effect and different types of attentional and motivational effects. Doubtless, people with disabilities may benefit from some alternative therapies, at least for relaxation, social interaction, personal development and self-esteem. This can be important because many children with learning difficulties suffer from low self-esteem.
For instance, a randomised controlled trial with dyslexic children was undertaken to evaluate the efficiency of Sunflower therapy which includes applied kinesiology, physical manipulation, massage, homeopathy, herbal remedies and neuro-linguistic programming. There were no significant improvements in cognitive nor literacy test performance associated with the treatment, but there were significant improvements in self-esteem for the treatment group. This study did not control for the placebo effect.

Famous quotes containing the words evidence and/or basis:
“In spite of the air of fable ... the public were still not at all disposed to receive it as fable. I thence concluded that the facts of my narrative would prove of such a nature as to carry with them sufficient evidence of their own authenticity.”
—Edgar Allan Poe (1809–1849)
“Knighterrantry is a most chuckleheaded trade, and it is tedious hard work, too, but I begin to see that there is money in it, after all, if you have luck. Not that I would ever engage in it, as a business, for I wouldn’t. No sound and legitimate business can be established on a basis of speculation. A successful whirl in the knighterrantry line—now what is it when you blow away the nonsense and come down to the cold facts? It’s just a corner in pork, that’s all.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
