Autism / Autism Spectrum Support Group
Autism is classified as a neurodevelopmental disorder which manifests itself in markedly abnormal social interaction, communication ability, patterns of interests, and patterns of behavior. Although the specific etiology of autism is unknown, many researchers suspect that autism results from genetically mediated vulnerabilities to environmental triggers.
I am also not sure if Autism, in some cases, might not be caused by undiagnosed and untreated hypothyroidism of the mother during pregnancy.
The best thing overall is to get him tested. For me, though, maybe the reason I was overlooked as hypothyroid my whole life was because I have autoimmune attacks on my thyroid from both directions, one destroying it and the other stimulating it to produce more thyroid hormones.
It is also likely that he is stressed or embarrassed at the hair loss, and could be stressed by untreated hypothyroidism.
One thing I was surprised at when I was finally treated, was how a huge burden of bodily stress was lifted off of me.
