BrightFocus Supports MarkVCID OCTA Biomarker Kit
The BrightFocus Foundation is teaming up with NINDS and MarkVCID to develop a novel OCTA Biomarker Kit. The kit seeks to use central retinal vessel density as a biomarker of susceptibility to small vessel VCID. Five MarkVCID research sites (USC, UCSF, JHU, UTHSCSA, and Rush) will participate in multi-site testing of the OCTA Kit, which is led by Dr. Amir Kashani at University of Southern California. The protocol was developed to assess an OCTA-based biomarker of retinal vessel skeleton density in the central macula.
Special acknowledgments to BrightFocus’ Vice President of Scientific Affairs, Diane Bovenkamp, PhD, for her guidance throughout the proposal process and to the donors of the Alzheimer’s Disease Research, Macular Degeneration Research, and National Glaucoma Research Programs at BrightFocus.

Alzheimer’s Disease-Related Dementias Summit 2019
MarkVCID investigators shared research and chaired sessions at the two-day Alzheimer’s Disease-Related Dementias (ADRD) Summit 2019 sponsored by the National Institute of Neurological Disorders and Stroke (NINDS) organized by NIH Lead Dr. Rod Corriveau and chaired by MarkVCID investigator Dr. Julie Schneider.
NINDS Director Walter Koroshetz in opening remarks emphasized research priorities including mixed and vascular dementias to assess the outcomes of the 2013 and 2016 ADRD Summits based on current science. Drs. Corriveau and Schneider followed with an overview of ADRD progress and updates to research recommendations.
Throughout the two days, MarkVCID investigators Drs. Myriam Fornage and Donna Wilcock presented and participated in panels discussing “Health Disparities in AD/ADRD” and “Vascular Contributions to Cognitive Impairment and Dementia” respectively. MarkVCID advisors Dr. Rebecca Gottesman and Ron Petersen also raised key topics including health disparities in AD/ADRD and strategies for identifying the needs of the research community.

GCBH discusses the Links between Vascular and Brain Health
Several MarkVCID principal investigators participated in the three-day 2019 Global Council on Brain Health (GCBH) Vascular Risk Issue Specialist Meeting, a collaborative effort of AARP. Issue specialists Drs. Charlie DeCarli, Sudha Seshadri, and Steve Greenberg discussed topics including the relationships between vascular and brain health, aging, and lifestyle to brain health. Drs. Marylin Albert and Ron Petersen (Mayo Clinic) served on the GCBH Governance Committee, and Dr. Debra Babcock served as conference liaison from the National Institute of Neurological Disorders and Stroke (NINDS).
The GCBH meeting aimed to assess vascular health by looking at current science and recommendations for maintaining and improving individual health. AARP will release a vascular health report shortly.

Alzheimer’s Association International Conference® (AAIC®) Previews MarkVCID’s First Wave of Biomarkers
NINDS Neurodegeneration Program Director & ADRD Program Lead Dr. Rod Corriveau presented MarkVCID's first wave of potential small vessel VCID biomarkers at AAIC that will be validated and prepared for large scale multi-site clinical research including interventional trials
Based on the Coordinating Center PI, External Advisory Committee, and NINDS leadership's review, five imaging-based and two fluid-based biomarker kits presented the most compelling rationale, scientific rigor, connection to small vessel disease, cognitive outcomes, and clinical trial readiness. After multi-site testing begins for the first wave, additional biomarker kits will be considered on a rolling basis.
To support the effort to identify and validate biomarkers, the Consortium has agreed to collaborate on a series of core MRI protocols, collect a core set of VCID-related clinical and cognitive data elements and biosamples, and adopt fluid sample collection best practices. Participating sites have also implemented sharing policies and procedures that ensure seamless cross-validation of biomarkers and exchange of data.
