Overview
Brief 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.

Eligibility Criteria
Inclusion Criteria
- •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 Criteria
- •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.
Outcomes
Primary Outcomes
CSF flow measurement
Time Frame: At the time of MR exam, approximately one hour
CSF flow will be measured in participants and compared between those with unimpaired brain function and those with clinical diagnosis of a disease that affects brain function, such as Alzheimer's disease and normal pressure hydrocephalus.
Secondary Outcomes
- White matter disease(At the time of MR exam, approximately one hour)
- Volume of CSF spaces(At the time of MR exam, approximately one hour)
