Alternative remedies of ASD

[Guest guest]

My son was diagnosed as ASD later last year. He is high function, but

with lots of behavior issues (can't keep his hands to himself,

extremely perfectionist, not following directions, easily distracted

and many other).

After some conventional approaches, including social groups, special

education, occupational therapy, sensory therapies, there have not been

much progress. My wife started to try alternative approaches, such as

homeopathy, chelation, biomedical (Pfeiffer Treatment Center), cfgf

diet and many other things. My questions are what are the downsides of

these remedies, besides money and time invested which already put lots

of stress in the family, on top of my son's behavior issues.

Appreciate your thoughts and comments.
