Chronic traumatic encephalopathy, abbreviated CTE, is a neurodegenerative disease due to repeated trauma.
The in the context of boxing it is known as dementia pugilistica; pugil is boxer in Latin.[1]
General
- Due to head trauma - usually repetitive.
- Seen in American football and boxing.
- May be associated with motor neuron disease.[2]
Microscopic
Features:[3]
- Wall-to-wall neurofibrillary tangles.
- Common in olfactory bulb, mammillary bodies, hippocampus.
- Usually perivascular around small blood vessels.
- Often superficial (unlike Alzheimer disease) and at the deep aspect of sulci.
- But not restricted to superficial regions of sulci (also deep in parenchyma).
- Staging according to Bienik et al.: NFT in <5 regions: low CTE, in 5 or more: high CTE.[4]
IHC
- Increased TDP-43 staining.
- p-Tau neuronal aggregates.
- +/. thron shaped-astrocytes.
- Usu. absence of beta-amyloid.
