Testing for brain injury

It seems that our 21st century wars have produced a significant number of brain injuries. So, the military has been pushed to develop tests for brain injuries. Unfortunately, the test they use,  the Automated Neuropsychological Assessment Metric (ANAM), is not doing the job, per ProPublica. Here are their reasons why. My emphases.

  • The people who invented ANAM and stood to make money from it were involved in the military's decision to use it, prompting questions about the impartiality of the selection process. No other tests received serious consideration. A report by the Army's top neuropsychologist circulated last year to key members of Congress labeled the selection process "nepotistic."
  • The Pentagon's civilian leadership has ignored years of warnings, public and private, that there was insufficient scientific evidence the ANAM can screen for or diagnose traumatic brain injury. The military's highest-ranking medical official said the test was "fraught with problems." Another high-ranking officer said it could yield misleading results.
  • Compounding flaws in the ANAM's design, the military has not administered the test as recommended and has rarely used its results. The Army has so little confidence in the test that its top medical officer issued an explicit order that soldiers whose scores indicated cognitive problems should not be sent for further medical evaluation.
  • Top Pentagon officials have misrepresented the cost of the test, indicating that because the Army invented the ANAM, the military could use it for free. In fact, because the military licensed its invention to outside contractors, it has paid millions of dollars to use its own technology.
  • The military has not conducted a long-promised head-to-head study to make sure the ANAM is the best available test, delaying it for years. Instead, a series of committees have given lukewarm approval to continue using the ANAM, largely to avoid losing the data gathered so far.
