Description
Josef Finsterer argues, in a 2026 letter, that brain-wave reactivity tests cannot cleanly predict recovery after traumatic brain injury. The letter discusses a study of 40 patients. Reactivity of the brain-wave test to sound and pain was present in 45 percent. Its absence tracked poor outcome scores at three and six months.
The objection is dependence: a reactivity reading only means something if the pathways carrying sound and pain signals to the brain are intact. Head trauma patients may also carry spinal cord or nerve damage. A flat response might then reflect a broken wire, not a hopeless brain. The reverse error is possible too. Finsterer asks how many study patients had such accompanying injuries, and notes that traumatic brain injury itself lumps together very different kinds of damage, complicating any single predictor.
