Summary

The Researchers are trying to test a MR imaging method for detection of Cerebral Spinal Fluid (CSF) flow in the brain to help diagnosis and better understand diseases that affect brain function.

Detailed description

The purpose of this research is to figure out if MR imaging can detect movement of CSF (fluid around the brain) to help better diagnosis and understand the cause of diseases that affect brain function. We are doing this research study to find out if movement of CSF is different between healthy adults and those with a disease that affects brain function.

Conditions

• Hydrocephalus
• Alzheimer Disease

Interventions

Type	Name	Description
OTHER	MRI screening form	Participants will be asked to complete a MRI screening form to check for the presence of metallic implants and materials. People with pacemakers, aneurysm clips, and cochlear implants, or metal/foreign objects in their eyes cannot have an MRI and will not be able to participate in the study.
DIAGNOSTIC_TEST	Urine pregnancy test	Pre-menopausal females will be asked if they think they may be pregnant. If yes, a urine pregnancy test will be performed.
DIAGNOSTIC_TEST	MR brain	You will be asked to lie down on the bed of the MRI scanner. Then a MRI coil/"antenna" will be placed over your head. This will allow us to get clearer pictures of the tissue of interest. The MRI machine makes loud knocking sounds. Because of this you will be asked to wear earplugs. You will receive a "squeeze ball" alarm in case you need urgent help. We will be able to talk with you and hear you during the MRI exam. The entire MRI scan will last about 45-60 minutes. The MR exam will include standard clinical images as well as the CSF flow imaging.
