Excessive vitamin D supplementation: a risk factor for autism
Some of the biochemistry that typically characterizes autism:
1) Th2 skew to the immune system. http://www.ncbi.nlm.nih.gov/pubmed/9627004
2) Overproduction of monoamine neurotransmitters. http://www.ncbi.nlm.nih.gov/pubmed/7914177
3) Oxidative stress. http://www.ncbi.nlm.nih.gov/pubmed/15585776
4) Vascular damage. http://www.ncbi.nlm.nih.gov/pubmed/16908745
5) Excessive neuronal connectivity. http://www.cell.com/cell-reports/fulltext/S2211-1247%2813%2900570-6
6) Extreme male brain. http://cogsci.bme.hu/~ivady/bscs/read/bc.pdf

My name is Seth Bittker and my son has been affected by ASD. After thinking about his development and carefully weighing the evidence I have come to the conclusion that oral vitamin D was a factor in inducing autism in him and I believe the same is true of a number of others.
