Dr. Fong's area of clinical expertise is cognitive disorders related to aging, including dementia and delirium. Throughout her career, she has made significant contributions and advances in patient care and research. Her goal and the main focus of her work is to reveal causes and advance treatments of cognitive decline and dementia. Her clinical activities includes an outpatient clinic in the Cognitive Neurology Unit at Beth Israel Deaconess Medical Center where she evaluates and treats patients with Alzheimer's disease, diffuse Lewy body disease, fronto-temporal dementia, vascular dementia, and mild cognitive impairment.
Dr. Fong's investigative work was born from her many years of clinical experience. Her major research efforts are focused on the clinical outcomes of delirium, specifically the onset of mild cognitive impairment (MCI) or dementia following an episode of delirium in the SAGES study. Dr. Fong has conducted a SPECT imaging study in delirious patients (Journal of Gerontology, 2006), a study demonstrating the negative impact of delirium on cognitive trajectory in patients with Alzheimer's Disease (Neurology, 2009, featured article), and a study comparing two widely used dementia screening tests (Alzheimer's & Dementia, 2009). More recently, Dr. Fong researched the increased risks for poor outcomes, including institutionalization, cognitive decline, and death following hospitalization in patients with AD (Annals of Internal Medicine, 2012).
