Asperger's (Causes)

Current research points to brain abnormalities as the cause of AS. Using advanced brain imaging techniques, scientists have revealed structural and functional differences in specific regions of the brains of normal versus AS children. These defects are most likely caused by the abnormal migration of embryonic cells during fetal development that affects brain structure and "wiring" and then goes on to affect the neural circuits that control thought and behavior.

Scientists have always known that there had to be a genetic component to AS and the other ASDs because of their tendency to run in families. Recent research indicates that there are most likely a common group of genes whose variations or deletions make an individual vulnerable to developing AS with varying severity and symptoms.
