The current study aims to validate several novel cognitive tasks expected to be sensitive to brain impairment in specific anatomic regions affected in preclinical Alzheimer's disease(pAD). The tasks are validated in 60 cognitively and clinically normal participants ages 60 - 85, inclusive, against reasonably well-established biomarkers of Alzheimer's disease, including 1) simultaneous positron emission tomography (PET) [18F]Flutemetamol amyloid and CT imaging and 2) to the extent data is available from other studies, participants' brain MRI and cerebral spinal fluid (CSF) amyloid and tau.

Eligibility | Inclusion Criteria: - Prior enrollment as a participant in the NYU Alzheimer's Disease Center (ADC) and completion of the ADC Clinical Evaluation within the past year. - Clinical diagnosis of "cognitively normal" or "amnestic mild cognitive impairment" based on recent (within 1 year) consensus meeting cross-referenced with standard neuropsychological scores. - Normal or corrected-to-normal vision and hearing (able to see images on computer screen and hear auditory events delivered through the computer speaker). Exclusion Criteria: - Significant history of mental illness, drug or alcohol abuse; severe trauma preventing normal use of dominant hand (needed to move the mouse cursor); clinical depression (unless medically controlled); other neurologic conditions (i.e. stroke), or learning disability; ophthalmologic/visual problems that prevent viewing a computer screen at a normal distance (such as legal blindness, detached retinas, occlusive cataracts). - Lack of capacity to give informed consent and no legally authorized representative to provide consent. - Having pacemakers, aneurysm clips, cochlear implants, or metal/foreign objects in body and therefore, unable to receive MRI. - Pregnancy, breastfeeding or planning to have a baby. |

Primary | Correlation of composite score on cognitive tests with biomarkers | The overall score on the cognitive tests will be correlated via a linear regression with biomarker data collected during the study. Each biomarker will be regressed individually. Biomarker data includes: MRI hippocampus (hipp) volume, entorhinal cortex (EC) volume, EC standard uptake value ratios (SUVRs), Hipp SUVR, precuneus (PCu) SUVR, PET-[18F] Flutemetamol SUVR, CSF Aß and tau levels, levels of diffusion tensor imaging mean diffusivity, and levels of fractional anisotropy. | 3 months | |
