ABSTRACT
Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease linked to repeated traumatic brain injury (TBI). This disorder is mainly observed in subjects at risk for brain traumatisms including boxers, American football and European football (soccer) players, as well as war veterans. Neuropathological findings are marked by abnormally phosphorylated tau accumulations at the depth of cerebral sulci, as well as TDP43, Aß and α-synuclein positive staining. It has been described 3 clinical variants the behavioural/mood variant, the cognitive variant and the mixed behavioural/cognitive variant. Cerebral MRI revealed signs of diffuse atrophy with abnormal axonal findings using the diffusion tensor imaging methods. Cerebral PET tau revealed increased standardised uptake value ratio (SUVR) levels in various brain regions of CTE patients compared to controls. The place of CTE among other neurodegenerative diseases is still debated. The focus of CTE management must be on prevention. The best way to prevent CTE in athletes is to put in place strict and appropriate measures by physicians. An individual with concussion should not be allowed to play again immediately (and sometimes never) in cases of abnormal neurological symptoms or imaging abnormalities.
