Gad Asher Marshall, MD

I received my medical degree from Boston University School of Medicine in 2000. I subsequently developed my interest in Alzheimer’s disease during neurology residency in Pittsburgh, under the guidance of Drs. Daniel Kaufer, Nicolaas Bohnen, and Steven DeKosky, and dementia fellowship in Los Angeles, with Drs. Jeffrey Cummings and Harry Vinters as my mentors. This has led me to my current faculty position at Brigham and Women’s Hospital and Massachusetts General Hospital, where I have had the fortune of working with Drs. Reisa Sperling and Keith Johnson, focusing on clinical trials and neuroimaging biomarkers in the Alzheimer’s disease spectrum.

I am currently Associate Medical Director of Clinical Trials at the Center for Alzheimer Research and Treatment at Brigham and Women’s Hospital; Associate Neurologist at Brigham and Women’s Hospital; Assistant in Neurology at Massachusetts General Hospital; and Assistant Professor of Neurology at Harvard Medical School. I have been site principal investigator for multiple clinical trials of amyloid-modifying drugs in Alzheimer’s disease. My research has focused on clinical correlates of activities of daily living, apathy, and executive function with PiB and FDG PET and CSF biomarkers. Most recently, I have been exploring the association between instrumental activities of daily living, executive function, and PiB PET in mild cognitive impairment. Building on my previous work, I am now developing a new scale of complex activities of daily living that will detect the earliest functional deficits at the stage of preclinical Alzheimer’s disease.
