It is important to consistently characterize the consequences of such sports activities in order to better advise society on the real risks to the central nervous system. We present the case of a former boxer reporting cognitive and behavioral symptoms that began six years after his retirement as a boxer, evolving progressively with parkinsonian and cerebellar features suggestive of probable chronic traumatic encephalopathy (CTE). Using our case as a paradigm, we extended the range of differential diagnosis of CTE, including corticobasal degeneration, multiple system atrophy, vitamin B12 deficiency, neurosyphilis, frontotemporal dementia and Alzheimer’s disease.engAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Chronic traumatic encephalopathyDementia pugilisticaDifferential diagnosisFrontal lobe dementiaCorticobasal syndromeMultiple system atrophyEncefalopatia traumática crônicaDdemência pugilísticaDiagnósticos diferenciaisDemência do lobo frontalDegeneração corticobasalAtrofia de múltiplos sistemasArtigo10.1590/1980-57642018dn12-010014
