MR Evaluation of Cerebrospinal Fluid (CSF) Dynamics

MR Evaluation of Cerebrospinal Fluid (CSF) Dynamics and Association of Intracranial CSF Flow With Brain Function

Sponsor

Mayo Clinic

Enrollment

50 participants

Start Date

Oct 31, 2019

Study Type

INTERVENTIONAL

Conditions

Alzheimer Disease Hydrocephalus

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.

Eligibility

Min Age: 18 Years

Inclusion Criteria3

A healthy control will be defined as an otherwise healthy person who does not have a medical condition that affects brain function or have problems with concentration, memory, balance, or coordination.
Patients who have a suspected diagnosis of altered CSF dynamics including but not limited to normal pressure hydrocephalus will be referred to Dr. Cogswell by their care team to be included in the study. Conditions of altered CSF dynamics include obstructive and non-obstructive hydrocephalus and may be associated with headaches and/or decreased cognitive function.
Similarly, patients with impaired cognitive function including but not limited to Alzheimer's disease will be referred to Dr. Cogswell by their care team to be included in the study.

Exclusion Criteria4

Subjects with non-MRI compatible devices
required sedation
women who may be pregnant will be excluded.
The first 10 subjects with normal pressure hydrocephalus will not have previously been shunted.

Interventions

OTHERMRI 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_TESTUrine 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_TESTMR 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.
