A study by the Veterans Administration Medical Centre in San Francisco, CA, has determined that of 103,788 records of returning soldiers from Iraq and Afghanistan, 25 percent had a mental health diagnosis.
Of the 25%, half of that group had 2 or more distinct conditions. Furthermore, fully one third of the overall group being examined were affected by at least one psychological diagnosis, most frequently post traumatic stress disorder.
Researchers found little difference in prevalence of diagnoses between gender or ethnic groups, but did find that those aged 18 to 24 years had a significantly higher risk of receiving a mental health diagnosis than
those 40 years or older.
