Family history of Schizoid Disorders and Autism. What are my chances of having a disorder as well?

Your odds are probably high, sorry. Many believe it can be prevented though. The going thoughts among the docs who are treating those with autism, is that it's from immune stress overload, and of course, some are more sensitive to this than others. Kind of like if you give a certain amount of poison to rats. Some will die, but not all. So, we say that the ones who lived were more healthier than the others, or had better immunity and genetics for various reasons. What I know is what is reversing autism symptoms, to include Bipolar, ADHD, OCD, and even more. It's accomplished by rebuilding the immune system by ridding toxins, pathogens, special diets, and nutrients. Much more is also done to reduce neuro-inflammation and increase circulation, etc. Some believe that those who are ill now, are just those who are "weaker" in some way, and that this problem will continue on it's alarmingly increasing rate. Some think those who are showing these chronic symptoms genetically can't rid toxins as well, or have issues with absorbing Vitamin D correctly or something else that makes them weaker. Many believe that their immune systems are skewed by vaccines or another immune stressor that makes them not fight off intracellular pathogens (lyme, Bartonella, mycoplasma, Epstein-Barr and other viruses, protozoa, etc.) See www.heidinotes.com for some insight. And want to add that low homocysteine is correlated with high IQ as well as higher rates of autism. Homocysteine is used by the body to rid toxins. But, there is a lot to learn in this area. Each family has it's own unique reasons why they are more susceptible, but generally speaking, the big causes are toxins, pleomorphic and intracellular pathogens, and electrosmog. They all reportedly work together to cause the disease state. See also autism.com.
