Chronic Traumatic Encephalopathy (CTE) might appear even after head impact in the absence of concuss

Researchers have found that early evidence of CTE pathology not only persisted for long after a head injury but also spread through the brain even in the absence of concussion. The study conducted in unanesthetized mice and post-mortem brains of teenage athletes showed that pathological aggregation of tau proteins were not only detected immediately at the site of impact but also in distant brain regions after 5 months. The study should be able to shed light on the relationship between CTE, head impact and traumatic brain injury so as to develop better therapeutic and preventive strategies.
