According to the researcher, Jennifer J. Vasterling of the Southeast Louisiana Veterans Health Care System and Tulane University Louisiana it was found that soldiers returning from Iraq showed mild problems with mental functioning.
They suffered from subtle lapses in memory and had difficulty in focusing on a particular issue.
They suffered from this condition for more than two months after their return from Iraq.
They lacked the quick grasping capacity and were not able to remember information as quickly as they were accustomed to.
These changes though are not alarming but are quiet evident when the individual tries to perform demanding jobs such as a challenging civilian job.
The study results appear in the Journal of Medical Association.
