When dementia is caused by AD, we refer to it as dementia of the Alzheimer's Type (DAT). The greatest risk factor for Alzheimer's Disease (AD) and DAT is advancing age, but DAT is not a normal part of aging. Studies have shown that changes in the brain happen before full symptoms of DAT develop. These changes include a buildup of two proteins within the brain, called amyloid and tau. The two goals of this study are (1) to determine whether patients with mild cognitive impairment or dementia-Alzheimer's type (DAT) are able to demonstrate decisional capacity to engage in PET amyloid and tau disclosure after receiving education; and (2) to assess how patients and care partners react to PET amyloid and tau biomarker disclosure.
