Of course not everyone has a heavy metal problem. Others only have a slight mercury problem and will, over time, have more Hg moved into their brain like the rats in this study. http://onibasu.com/archives/am/74605.html
They won't associate the decrease in stress tolerance, coordination, memory, and increases in brain fog to the ALA. So they'll go back to the doctor for additional treatment$$$. Nice gig, huh?
I made a note of these reports that I've come across over the years.
Inappropriate use of ALA. Sometimes it takes a while for the effects of inappropriate use of chelators to be obvious to adults, let alone autistic kids. These are some examples from adults, some of whom actually had gains in some areas initially but then realized damage was being done, usually to the brain as Hg levels likely increased.
-I know a guy at work who has gotten nice improvement in his neuropathy from inappropriate use of ALA; however he looks really foggy and whifty even though he is obviously well educated. He reminds me of my foggy brain before I started to chelate. This is doubly sad because he has a 20-something high-level autistic son. The boy would likely benefit from appropriate use of ALA and the boy needs his aging father to be sharp and healthy to help him heal!
