"Early signs of mercury poisoning in adults are nervous system effects, including narrowing of the visual field and
numbness in the extremities. Exposure to mercury in utero and in children may cause mild to severe
mental retardation and mild to severe motor coordination impairment.

"Exposure to mercury can cause immune, sensory, neurological, motor, and behavioral dysfunctions similar to traits defining or associated with autism, and the similarities extend to neuroanatomy, neurotransmitters, and biochemistry. A review of medical literature and US government data suggests that: (i) many cases of idiopathic autism are induced by early mercury exposure from Thimerosal; (ii) this type of autism represents an unrecognized mercurial syndrome; and (iii) genetic and non-genetic factors establish a predisposition whereby Thimerosal's adverse effects occur only in some children." - Autism: A novel form of mercury poisoning
