Our research team in the Aging & Brain Health Research (ABHR) Group is focused on developing new tools to determine individual risk for age-related neurological and psychiatric disorders, and to leverage this information to develop new prevention and treatment interventions.

Neurological and psychiatric disorders affecting the elderly are a major contributor to disability and mortality worldwide. The numbers describing this “epidemic” are truly sobering.

One person in three over the age of 65 will develop dementia in their lifetime. Three quarters of the approximately 800,000 strokes diagnosed in the US each year will affect people over the age of 65.

One in every fifteen individuals above age 65 suffers from depressive symptoms, with 20% of suicides occurring in this age category. We are committed to ensuring these numbers are drastically reduced over the next few years.

Our Mission: To transform brain aging and health through innovative scientific research.

Our mission

Our Research Philosophy

We urgently need new ways of diagnosing, preventing and treating conditions caused by abnormal brain aging. Our research group is focused on incorporating various scientific tools to study brain aging in the most comprehensive way possible.

We believe that these problems are far too large in scope and complexity to be addressed using only one (or a few) approaches.

Our research strategy incorporates aspects of neuroscience, genomics, public health, brain imaging, mathematics and computer science. We collaborate with many colleagues who bring additional expertise and different perspectives to our work.

We also recognize that brain aging research and medical care must, by necessity, be highly personalized to each individual.

For this reason we joined the nascent field of precision medicine, a revolutionary approach to clinical research that places individuals at the center of the scientific process.

Unlike traditional scientific efforts, precision medicine takes into account individual variability in genes, environment, and lifestyle for each person.

Our Group Values and Bywords (5 I’s):

Impassioned: We combine scientific integrity with steadfast dedication and advocacy for patients and families

Inclusive: We are dedicated to diversity and service to underprivileged groups in clinical care, research, recruiting and mentoring

Innovative: We apply cutting edge tools in both research and care delivery, and develop new ones to address unmet needs

Interconnected: We strive to communicate to the widest lay and scientific audiences possible, empowering our message and service

Interactive: We always seek to engage with patients, public and peers to reshape our grand strategic goals and research direction

Research Projects

Clinical Manifestations of Cerebral Small Vessel Disease (CSVD)

Cerebral Small Vessel Disease (CSVD) is a degenerative condition affecting the microscopic blood vessels of the brain, causing them to weaken over time. It is an extremely common condition among the elderly, and is responsible for a number of frequent disorders of brain aging, including hemorrhagic and ischemic stroke, depression, dementia and gait impairment.

The Healthy Brain Aging Research group is focused on identifying individuals at risk for each of these clinical manifestations of CSVD, with a specific focus on personalized risk profiles.

Cerebral Small Vessel Disease

Predicting Cognitive Impairment after Hemorrhagic Stroke

Intracerebral Hemorrhage (ICH) is the most common form of hemorrhagic (i.e. bleeding) stroke, and affects almost 80,000 patients in the US alone every year. As mentioned above, ICH is caused by rupture of microscopic blood vessels in the brain, leading to internal bleeding.

Patients that survive this acute neurological injury are at very high risk to develop cognitive impairment, up to and including dementia.

This project seeks to identify those patients at higher risk, and understand which factors increase or decrease the likelihood of developing dementia after and hemorrhagic stroke. We hope to use this information to prevent dementia among survivors of hemorrhagic stroke.

Vascular Depression Study

Vascular depression is a common form of depression affecting elderly individuals with vascular risk factors, especially those with high blood pressure and/or stroke.

The Aging & Brain Health Research Group is studying individuals with hemorrhagic stroke, one of the patient groups at high risk for vascular depression.

This project seeks to provide a comprehensive assessment of risk factors for vascular depression. In turn, better understanding of vascular depression will assist in patient counseling, guide researchers world-wide in developing more effective treatments, and may lead to strategies to prevent this common brain disorder of aging.

Research Positions

Visiting Scholar Program: We are enthusiastic about offering external scientists the opportunity to join us in our daily research work and exchange new ideas and perspectives. We welcome individuals at different levels of clinical/academic training, with specific focus on providing students and trainees (undergraduate and graduate students, medical students, residents, and fellows) with exposure to clinical research in the fields of neurology and psychiatry. Each application is handled and considered individually.
