Experiencing a single traumatic brain injury could set off an Alzheimer's-like neurodegeneration, research has indicated.
Co-senior author Douglas Smith, of the University of Pennsylvania, said the results emphasise the seriousness of a single traumatic brain injury both in the long and short term.
Years after a single traumatic brain injury, researchers found both tau tangles and amyloid-beta plaques - Alzheimer's hallmarks - in the brains of survivors.
This suggests that an Alzheimer's-like process may be initiated or accelerated following a single traumatic brain injury.
"Plaques and tangles are appearing abnormally early in life, apparently initiated or accelerated by a single TBI," confirmed Mr Smith.
In other news, a study conducted at Loyola University Health System has indicated that former sportspeople could be at an elevated risk of mild cognitive impairment.
A group of NFL football players with an average age of 61 were assessed, and it was revealed that 35 per cent of players had possible mild cognitive impairment - a potential precursor to Alzheimer's disease.
