Why does my child have episodes of anger and try to injure himself?

The aggressive behavior is often from underlying damage to the autonomic nervous system (ANS). When damaged, the ANS is often unable to regulate the proper flow and pressure of blood and oxygen into the brain causing the child to feel unusually anxious, fearful, angry, and aggressive. Over time the protocol will resolve this. **This is a complicated topic. You may want to read Chapter 13 in our book where I cover this in great detail.
