There can be problems in the immune system of pregnant woman or developing child which might act as the root cause of autism. As when the autistic subjects are examined by doctors it comes to light that their immune system is also affected and functions at a lower level which serves to suggest that whatever causes autism disrupts the immune system to a large extent. While the idea of abnormality in the immune system as the cause of autism is one of many proposed theories and in the past the focus of the studies was adaptive immunity, such as production of anti-biotic to fight off invading viruses and the claims regarding the MMR vaccines in triggering autism fall in this category (Randerson.paraphrase). The results of some case studies suggested that paracetamol (acetaminophen, Tylenol) is also associated with the autistic disorder among children (Meadows and Mandel.paraphrased).
