A professor at the Indiana University of Medicine has been given a grant to research whether a nasal spray could safely deliver an anti-depressive chemical to the brain, helping curb suicidal thoughts.
The naturally-occurring chemical thyrotropin-releasing-hormone -- or TRH -- has trouble reaching the brain through pills or injection.
The military hopes a nasal spray will be a more effective delivery method.
The Army counted 38 confirmed or suspected suicides in July alone and at least 120 so far in 2012.
