*Abbreviated ''CTE''. | |||
===General=== | |||
*Due to head trauma - usu. repeated. | |||
**Seen in ''American football'' and ''boxing''. | |||
*May be associated with motor neuron disease.{{Cite journal | last1 = Daneshvar | first1 = DH. | last2 = Riley | first2 = DO. | last3 = Nowinski | first3 = CJ. | last4 = McKee | first4 = AC. | last5 = Stern | first5 = RA. | last6 = Cantu | first6 = RC. | title = Long-term consequences: effects on normal development profile after concussion. | journal = Phys Med Rehabil Clin N Am | volume = 22 | issue = 4 | pages = 683-700 | month = Nov | year = 2011 | doi = 10.1016/j.pmr.2011.08.009 | PMID = 22050943 }} | |||

*Wall-to-wall neurofibrillary tangles. | |||
**Common in olfactory bulb, mammillary bodies, hippocampus. | |||
**Usually perivascular. | |||
**Often superficial (unlike [[Alzheimer disease]]) and at the deep aspect of sulci. | |||
