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.
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.
