But didn't find the word Thimerosol (Thimerosal) there, Chuck.

Rather, it says:

"What causes autism?
Scientists aren¹t certain what causes autism, but it¹s likely that both
genetics and environment play a role.    
Researchers have identified a number of genes associated with the disorder. 
Studies of people with autism have found irregularities in several regions
of the brain.  
Other studies suggest that people with autism have abnormal levels of
serotonin or other neurotransmitters in the brain. 
These abnormalities suggest that autism could result from the disruption of
normal brain development early in fetal development caused by defects in
genes that control brain growth and that regulate how neurons communicate
with each other.  
While these findings are intriguing, they are preliminary and require
further study.  
The theory that parental practices are responsible for autism has now been
disproved." 


Neither could I find Thimerosol (Thimerosal) in association with Autism when
doing a search either on:

Kaplan & Sadock's Comprehensive Textbook of Psychiatry

which is more concerned with a slow discontinuation of Thimerosal in
manufacturing vaccines against Hepatitis B.
 
Here it says that:
"The immunogen is suspended or dissolved in sterile water or saline, or in
more complex media such as tissue culture medium, which may contain
constituents from the biologic system used to produce the immunogen. Most
vaccines contain preservatives and trace amounts of antibiotics such as
neomycin to prevent bacterial overgrowth. Some vaccines contain adjuvants
such as aluminum hydroxide and aluminum phosphate that also help to retain
the immunogen at the site of inoculation for a prolonged time, thus
increasing antigenic stimulation. The theoretical cumulative toxicity of
mercury in thimerosal-containing vaccines has led to the development of
thimerosal-free vaccines. All vaccines routinely administered to children
are now free of thimerosal".
 
Regarding Autism, found this other interesting and short article:

Enjoy,
