A post-mortem examination shows a New Zealand professional rugby player who died by suspected suicide last year had advanced chronic traumatic encephalopathy (CTE), a brain abnormality linked to repeated concussions. The diagnosis was announced Thursday by Coroner Ian Telford who is conducting a preliminary hearing into the death of Shane Christie who died in August aged 39. Christie believed he was suffering from CTE and campaigned for greater understanding of the condition after the death of his friend and fellow rugby professional Billy Guyton, also by suspected suicide.
