In an article published today in The New England Journal of Medicine, two Army mental health researchers — Cols. Charles Hoge and Carl Castro — say the Pentagon and Department of Veterans Affairs “are overemphasizing mild traumatic brain injury among combat troops at the expense of other medical problems that are going untreated.” Castro and Hoge say “the military should scrap screening questions meant to uncover cases of mild traumatic brain injury (TBI) among troops returning from combat,” as “most troops who suffered a concussion in battle recovered within days of the injury.” Their article adds that symptoms blamed on TBI are more likely due to depression, PTSD, or substance abuse. Their article is the latest in a string of recent stories indicating that cases of PTSD are going largely unnoticed by the Pentagon. Last month, the Air Force Times reported that as many as 300,000 troops had PTSD but received inadequate care with only about half of all claims for the condition being approved. Just last week, Salon reported that, according to a secretly recorded audio tape, a psychologist told his soldier patient that many doctors are being pressured to not diagnose PTSD and diagnose anxiety disorders instead. Gen. Eric Schoomaker, the Army’s surgeon general, has been convinced by Casto’s and Hoge’s report and has said that the screening process should be changed.
