Developing Advanced Blood-Brain Barrier Permeability Imaging for Early AD

January 29, 2024 updated by: NYU Langone Health

Developing Advanced Blood-Brain Barrier Permeability Imaging for Early Alzheimer's Disease

Aging is the primary risk factor in aging-related dementia. An important initiating factor for the development and progression of cognitive impairment is disruption of the blood-brain barrier (BBB). BBB plays an important role in maintaining normal brain homeostasis and protecting neural tissues from toxins. It is hypothesized that such changes known to be common in aging and can be an early process that precedes Alzheimer's Disease (AD). The microvascular changes related to subtle BBB disruption can be measured with permeability-surface area (PS) derived from GRASP DCE-MRI acquired less than 10 minutes, and the patterns of increased PS in normal and abnormal aging are different.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Healthy cognitively normal control subjects of both age cohorts will be recruited by the study coordinator from (i) a pool of established volunteer subjects at NYU Langone Health who previously participated in research and who have agreed to be contacted about future research, (ii) Health Insurance Portability and Accountability Act of 1996 (HIPAA)-compliant databases such as RedCap and DataCore, and (iii) individuals who have contacted NYU to express interest in participating in research as a healthy volunteer.

Subjects with aMCI will be recruited by Dr. Wisniewski from an ongoing NIH-funded large grant at NYU Barlow Center.

Description

Inclusion Criteria:

  • Subjects that have been diagnosed with aMCI ages 65-85

Exclusion Criteria:

  • Pregnant, planning to get pregnant, or nursing.
  • Claustrophobia
  • Cardiac pacemaker
  • Intracranial clips, metal implants, unremovable jewelries, metal in eyes.
  • History or presence of any other major medical, neurologic or psychiatric conditions, such as Alzheimer's diseases, Parkinson's diseases, and stroke.
  • Renal or liver disease as this may cause concerns related to Gad-based contrast agent
  • Allergy to the contrast agent Gadolinium
