(NaturalNews) Many violent behaviors can be caused by brain abnormalities. In light of the Newtown mass shooting, people are asking, “What is the motive?” There is no motive. There is no rational reason. The actions are caused by brain chemistry that is imbalanced, and then something happens to trigger the scales into carrying out violent acts. Sadly, antidepressants and the very drugs prescribed for these individuals can be a trigger that set the bonfire in their brain ablaze.
