[Chronic traumatic encephalopathy]

Area of Science:

• Neurology
• Neuroscience
• Sports Medicine

Background:

• Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease linked to repetitive head impacts, often seen in contact sports.
• Current diagnosis relies on post-mortem neuropathological examination, delaying identification.
• CTE symptoms include behavioral changes, cognitive decline, and motor deficits, often appearing years after exposure.

Purpose of the Study:

• To review the current understanding of Chronic Traumatic Encephalopathy (CTE).
• To emphasize the critical need for validated ante-mortem diagnostic criteria for CTE.
• To discuss the implications for early detection and management of CTE.

Main Methods:

• Literature review of existing studies on CTE.
• Analysis of neuropathological findings and clinical presentations.
• Discussion of diagnostic challenges and future research directions.

Main Results:

• Repetitive head impacts are a significant risk factor for CTE.
• Distinct neuropathological hallmarks are observed post-mortem.
• Clinical manifestations are diverse and progressive, impacting quality of life.

Conclusions:

• There is an urgent need for validated clinical and neuropathological criteria for ante-mortem CTE diagnosis.
• Developing reliable ante-mortem diagnostic tools is crucial for patient care and research.
• Improved diagnostic capabilities will aid in understanding CTE's progression and impact.
