During World War II, it was called shell shock. During the Vietnam War it was called the Vietnam Syndrome. It wasn't until 1980 that psychologists had an official term for the condition: Post-Traumatic Stress Disorder.
With the recognition of PTSD as a psychological condition, large-scale studies of the disorder began, said Dr. Rumi Kato Price, professor of psychiatry at Washington University School of Medicine.
"Now we have very well established evidence-based treatments for PTSD," said Price. "That took three decades (to develop)."
Florian Schulz has two passions. He is an award-winning wildlife photographer, but is equally dedicated to preserving the habitat of wildlife.
Schulz’s passions led him to the Arctic where he spent 18 months in search of breathtaking images documenting life in every season. The result is the book “To the Arctic” which is the companion to the IMAX film of the same name.
