Omura reports on a non-invasive method developed to detect neurotransmitters, bacteria, metals, virus, and other abnormal molecules using an electromagnetic field resonance phenomenon through the pupil of the eye.
The researchers found that in autism the acetylcholine was reduced while certain Alzheimer’s markers were increased. They also detected elevated asbestos, titanium dioxide (TiO2), aluminum, and mercury, as well as decreased dopamine, serotonin, and GABA – up to on tenth of normal. Viral and bacterial infections were also detected accompanying the above abnormalities. Omura et al claim that more significant improvement is possible when these abnormalities are treated as early as possible, before damage to brain tissue becomes permanent.
NOTE: The authors say that titanium dioxide by itself may be less toxic, but in autism it appears to accumulate in the brain with asbestos, aluminum, and/or mercury. Some more studies on TiO2 listed in the References of this article:
