Vascular brain injury may be linked to mild cognitive impairment, but the accumulation of beta amyloid protein does not seem to be connected to MCI, according to a study published in JAMA Neurology. There was also no indication that vascular brain injury and the buildup of beta amyloid protein, conditions that often occur together, are inter-related, the study said. Researchers used MRI to identify infarcts and PET imaging with Pittsburgh Compound B to assess beta amyloid. "If there is an association between vascular risk and beta amyloid, it does not appear to be mediated by vascular brain injury," researchers said.
