Gad A. Marshall
I have a long-standing interest in clinical-pathologic and imaging correlates in Alzheimer's disease. Most recently, I have been using PET imaging to assess the relationship between apathy, executive function and instrumental activities of daily living, in vivo amyloid deposition (PiB PET) and synaptic integrity (FDG PET) in mild cognitive impairment and mild Alzheimer's disease.
My other main research interest and involvement is in clinical trials for the treatment of Alzheimer's disease.
More Information: Marshall Profile
During my medical education at the Boston University School of Medicine, medical internship/neurology residency at the University of Pittsburgh and dementia fellowship at the University of California, Los Angeles, I developed both my clinical and research interests in Alzheimer's disease. Along the way, I have collaborated with multiple investigators who encouraged and nurtured my drive to better understand this devastating disorder and find effective treatments.
I currently work as a behavioral neurologist at the Brigham and Women's Hospital and the Massachusetts General Hospital, focusing on clinical trials and neuroimaging biomarkers in Alzheimer's disease and its precursor stages.
