Neurotrack Test Validation Protocol

The Neurotrack test has the potential to dramatically alter the current methods used for detecting cognitive deficits. Patients and research subjects could be screened for medial temporal lobe (MTL) impairment using inexpensive, widely available, safe, and non-invasive technology. Subjects will be elderly individuals who are participating in ongoing research at the NYU Alzheimer's Disease Center (ADC) and who have received the standard ADC clinical evaluation within the past year, including a medical-neurological evaluation, neuro-psychological assessment and structural neuroimaging (MRI). As part of the current study, all subjects will receive both the Neurotrack Visual Paired-Comparison (VPC) Task and MRI scans. The current protocol strictly for a research study and there will be no "standard care" provided. Participants will be asked to come in for two separate sessions. The first session will involve screening to confirm eligibility and administration of the cognitive testing procedures, while the second session will involve the MRI protocol.
