Navigating CTE Claims: A guide for insurers

Chronic traumatic encephalopathy (CTE) is a neurodegenerative brain condition increasingly linked to repeated head injuries and concussions, particularly in elite sport.

As awareness of CTE grows, insurers are beginning to face a complex and evolving risk exposure, shaped by emerging medical research, developing case law and heightened regulatory scrutiny. Adding to this complexity, a definitive diagnosis of CTE is currently only possible following post‑mortem examination.

While known claims have to date been largely confined to elite sport, the CTE claims landscape is expected to develop rapidly as medical understanding advances and litigation expands in Australia and internationally. Insurers are therefore closely monitoring how liability, causation and quantum issues may unfold across a broader range of insured risks.

Prepared by Barry Nilsson’s national Insurance & Health team, this comprehensive guide provides an in‑depth analysis of CTE from an insurance and claims perspective, including:

• a medico‑legal overview of CTE and current medical understanding
• emerging CTE claims in Australia and key overseas developments
• the evolving legislative and regulatory framework
• potential exposure pathways and claimant cohorts, and
• practical implications for insurers across underwriting, claims and risk mitigation.
