Dementia pugilistica

Dementia pugilistica (DP) is a type of chronic traumatic encephalopathy (CTE), a neurodegenerative disease with features of dementia. DP may affect amateur or professional boxers, wrestlers as well as athletes in other sports who suffer concussions. DP is also called chronic boxer's encephalopathy, traumatic boxer’s encephalopathy, boxer's dementia, chronic traumatic brain injury associated with boxing (CTBI-B), and punch-drunk syndrome. DP was historically considered equivalent to CTE but is now considered a subtype of CTE.
