Longer Amnesia Predicts More Brain Atrophy

Post-traumatic amnesia (PTA) has long been used as a predictor of outcome in those with TBI. A recent study (Wilde, EA, Bigler, ED et al. 2006) showed that a correlation between the duration of PTA in the existence of atrophy of brain tissue following an accident exists. The longer the period of PTA the higher the rate of brain tissue atrophy following an injury.
