Figures & data
Fig. 1. The pie chart illustrates the most likely risk factors for autism. At issue is the way in which these factors act either independently and/or though various interactions to produce autism. To date, much of this remains to be determined.
Fig. 2. Putative critical windows of developmental vulnerability for autism are shown based on reports involving potential environmental risk factors. Information is included from human studies as well as from animal data. References for each risk factor and window are as follows: Viral Infection—Hospitalization Citation92, Absence of Food Aversion and Vomiting Citation44, Misoprostal Citation70, Thalidomide Citation109, Valproic Acid Citation37, Bacterial Infection—Hospitalization Citation92, Murine Viral Infection Citation110, Generalized Maternal Stressors Citation102, Terbutaline Citation111, and Vitamin D Deficiency Citation77.
