Detection of brain amyloid β deposition in patients with neuropsychological impairment after traumatic brain injury: PET evaluation using Pittsburgh Compound-B

Abstract

The absence of Aβ deposition in many patients with chronic neuropsychological impairment after TBI does not support the premise that Aβ pathology progresses over time in the traumatized brain. Early and sequential (11)C-PIB PET examination may clarify the time course of Aβ deposition in the traumatized brain and the relationship between traumatic brain insult and subsequent neuropsychological impairment.
