TBI

An epidemiological association between traumatic brain injury (TBI) and Alzheimer's disease (AD) has long been established.  Interestingly, an increase in beta amyloid  (one hallmark of AD) directly following TBI has been observed.  In fact, it has been reported that with a greater level of TBI comes a higher risk of developing AD, or other neurodegenerative disorders, in the future.  Roberts et al first presented research that beta amyloid plaques found in TBI patients are very similar to those found in AD patients.
