abstract="The clinical symptomatology and pathogenic mechanisms of chronic traumatic brain injury associated with boxing (CTBI-B) is reviewed. This syndrome is also known as punch drunk syndrome or dementia pugilistica. Since even milder forms of CTBI-B are rare among amateur boxers, we make a distinction between amateur and professional boxing throughout the review. Focus is also set on the interesting similarities in neurochemical changes and pathogenic mechanisms between CTBI-B, acute traumatic brain injury (e.g. road traffic accidents) and Alzheimer's disease.",
