Biomarker videos

As research advances in the area of Alzheimer’s disease, greater emphasis is being placed on the study of biomarkers. These videos are designed to help you understand why we ask our Clinical Core research participants to undergo biomarker visits and offer a general overview of how the procedures are conducted. 

The first three videos describe an MRI (Magnetic Resonance Imaging) procedure, which is an imaging technique that uses a strong magnet, radio signal, and computer to produce detailed pictures of the inside of your body, as well as a lumbar puncture (LP), during which a clinician uses a needle to draw cerebrospinal fluid (CSF). The last two videos describe a PET (Positron Emission Tomography) scan, which is an imaging technique that uses a radiotracer and computer to create a detailed picture of what is happening inside the body. 

The information collected during these tests may one day help us learn how early Alzheimer's disease starts so that we can prevent and treat the disease.
