The Knight Ridder news agency is reporting the Department of Veterans Affairs is on a pace to see nearly 20,000 new cases of post-combat stress this year among service members who’ve served in Iraq or Afghanistan. This is more than six times the number of cases that officials had expected. Meanwhile the Washington Post is reporting that thousands of Vietnam veterans are now seeking help for post-traumatic stress disorder–more than 30 years after their war ended. Experts say one reason appears to be harrowing images of combat in Iraq.
