(Daily Beast) – You don’t have to be fighting in a war to suffer irrevocable brain damage from one. That’s the finding from a new United Nations report released this week showing that an estimated 87 million children under the age of 7 have lived their entire lives in conflict zones, an environment so stressful that it has the potential to significantly impact the development of their brains. The discovery stems from a report released by the United Nations Children’s Fund (UNICEF) Thursday, an organization that works to bring resources to children in the 22 countries affected by conflict worldwide. Earlier this year the organization released a report showing that one in four of the more than 100 million school-age kids living in these zones are not in school.
