Research has shown that children with autism also have organic xenobiotics like ADHD children. It is found that functional liver detoxification testing – such as caffeine, acetaminophen, and aspirin clearance – may also be abnormal in autistic children. It is not definitive, but autism may be an indication of a primary neurotoxicologic disorder that stems from fetal and infant exposure to xenobiotics. The issue this presents at such a young age is that the blood-brain barrier is poorly developed and combined with potential inherited insufficiency of liver detox mechanisms, problems may arise. It is a possibility that autism and ADHD may be part of the same spectrum of disorders and share quite a few etiological features. What do you think of this?
