Chelation Therapy
Description: A treatment that aims at lowering the levels of mercury, lead, or other heavy metals, in one’s body. The participant takes medication every other week or on some regular schedule until the urine levels are reported to stabilize. Then, the participant takes lipoic acid which chelates the metal that is tightly bound to the cells.
Research Summary: There have been no scientific studies of chelation therapy for individuals with autism spectrum disorders. It is doubtful that individuals with autism spectrum disorders have high levels of heavy metals or that chelating agents would be effective in reversing neurological damage from metal exposure (Levy & Hyman, 2005). Some forms of chelation therapy may cause severe side effects or even death (Kane, 2006). Thus, this therapy appears implausible and unacceptably risky; as such, it is an inappropriate treatment for autism spectrum disorders.
Recommendations: Chelation therapy is not recommended as a treatment for autism spectrum disorders.
