Doctors at Johns Hopkins Hospital in Baltimore say that when the mother of an autistic child is pregnant her immune system develops antibodies that can attack the unborn baby's brain, just like antibodies do when they fight off a virus or infection.

They say these antibodies can go through the placenta and cause inflammation in the baby's brain. The study was done with human mothers' antibodies put in mice which caused the newborn mouse pups to act autistic.

Doctors in the study caution that they are comparing mice and humans, but still there was strong evidence that the pups were affected and had autistic traits. Since autism is so complex they say this may be only one of several factors involved in the condition. The study is in the April Journal of Neuroimmunology.

Also, if you suffer from fibromyalgia, ask your doctor about this new study: Stanford University doctors tested a drug that is used to treat drug and alcohol addiction on people with Fibromyalgia. They found that it helped relieve pain and fatigue by 30 percent in some patients. Some people even came off of all other medications and went back to work.

But the doctors caution it was a small study and they are moving into a bigger study on more people. The drug they are using in the studies is a low dose of Naltrexone.
