News — January 19, 2022, CLEVELAND: Cleveland Clinic has launched a landmark study to better understand why millions of people around the world suffer from brain diseases, with the goal of pinpointing disease biomarkers early, well before clinical symptoms present themselves.  

The new – the largest clinical study ever for brain disease – will collect data from up to 200,000 neurologically healthy individuals over a 20-year period to identify brain disease biomarkers and targets for preventing and curing neurological disorders.

One in every six people around the globe has a neurological disease such as Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, stroke or epilepsy. While the medical community has learned to manage some symptoms of brain disorders, it remains challenging to predict who will become sick or how to cure – or even stop the progression of – these diseases once they are diagnosed.

Led by , and , of Cleveland Clinic’s Neurological Institute, the longitudinal multi-year study is an enterprise-wide undertaking, enlisting a multidisciplinary team of physicians and scientists from across the global health system. The study launched at Cleveland Clinic’s main campus in Cleveland and will expand to additional Cleveland Clinic sites over time.

“Disrupting neurological diseases is one of the greatest challenges of our time and motivates our clinicians and scientists every day,” said Dr. Machado, chair of the Neurological Institute and the Charles and Christine Carroll Family Endowed Chair in Functional Neurosurgery. “By launching a study of this magnitude, we have the potential to discover causes of neurological disorders and what happens before symptoms become obvious – the silent phase. Our hope is to change the course of neurodegeneration, with the long-term goal of curing diseases in their earliest stages, years before symptoms are even seen. Achieving this will be a great gift to our children and grandchildren. We can make neurological care better for the next generations.”

The initial phase of the study will enroll 10,000 volunteers over the first five years who will be examined and thoroughly investigated. This will include adults 50 years and older with no known neurological disorder or neurologically healthy adults age 20 and older who have a first-degree relative diagnosed with multiple sclerosis. Volunteers do not have to be current Cleveland Clinic patients. Participants will undergo yearly assessments including neurological examination, bloodwork, eye retina scans, brain MRIs, EEG and sleep studies and other cognitive function tests.

Using advanced computing tools, researchers will collect data points from the study volunteers. Collectively, these data points will form a trend line to capture the genetic risk factors, and invisible molecular, structural, neurophysiological and cognitive/memory changes in the brain over time. Researchers will seek “disease fingerprints” to help guide diagnostic and preventative medicines.

“By researching at-risk healthy individuals over the course of 20 years, we will learn what is happening to the brain and body before a neurological disease is diagnosed. This research will help understand the mechanisms of brain diseases and lead to the design of preventive treatment for neurological diseases. This is precision medicine in its best form,” said Dr. Najm, vice chair of the Neurological Institute for Strategy and Development and director of Cleveland Clinic's Charles Shor Epilepsy Center and the Joseph H. and Ellen B. Thomas Endowed Chair in Epilepsy. “We’re building a foundation to screen one person at a time – potentially with something as routine as a blood test – to diagnose brain disease on the spot and prevent it from happening altogether.”

Philanthropic contributions are funding the study in part, with gifts of all sizes pooled to support the research. Philanthropy is vital in the mix of funding that is launching the research and moving it forward.

About Cleveland Clinic

is a nonprofit multispecialty academic medical center that integrates clinical and hospital care with research and education. Located in Cleveland, Ohio, it was founded in 1921 by four renowned physicians with a vision of providing outstanding patient care based upon the principles of cooperation, compassion and innovation. Cleveland Clinic has pioneered many , including coronary artery bypass surgery and the first face transplant in the United States. U.S. Â鶹´«Ã½ & World Report consistently names Cleveland Clinic as one of the nation’s best hospitals in its annual “America’s Best Hospitals” survey. Among Cleveland Clinic’s 67,554 employees worldwide are more than 4,520 salaried physicians and researchers, and 17,000 registered nurses and advanced practice providers, representing 140 medical specialties and subspecialties. Cleveland Clinic is a 6,026-bed health system that includes a 165-acre main campus near downtown Cleveland, 19 hospitals, more than 220 outpatient facilities, and locations in southeast Florida; Las Vegas, Nevada; Toronto, Canada; Abu Dhabi, UAE; and London, England. In 2019, there were 9.8 million total outpatient visits, 309,000 hospital admissions and observations, and 255,000 surgical cases throughout Cleveland Clinic’s health system. Patients came for treatment from every state and 185 countries. Visit us at . Follow us at . Â鶹´«Ã½ and resources available at
