In the book Amalgam Illness by Andrew Hall Cutler the author has an excellent explanation on why ALA chelation is the only safe, effective means to remove mercury from the Brain and CNS.
In short: metalic mercury, organic mercury, methylmercury and ethylmercury are all processes by the body and can then be transformed into inorganic mercury.
When this happens in the brain and CNS the inorganic mercury is trapped. The body has no mechanism for getting it out past the Blood Brain Barrier.
Alpha Lipoic Acid is the only safe and effective chelator that we currently have available to us which can cross the blood brain barrier and remove inorganic mercury from the brain.
Mercury has the potential to cause many of the same behavioral symptoms seen in children with Autsim. If mercury is the root cause for the behavior and physical symptoms the person is suffering from, then appropriate, safe chelation has the potential to recover the person from the ailments they are experiencing.
In my opinion since ALA is a wonderful Antioxident when not in the presance of heavy metals and has the potential to offer relief if the symptoms are caused by metals it only makes sense to give it a whirl. See Safe Chelation for details.
