Familial Dementia Neuroimaging Lab

The Familial Dementia Neuroimaging Lab is focused on the study of age-related cognitive and brain changes that may predispose individuals to develop dementia later in life


The Familial Dementia Neuroimaging Lab is focused on the study of cognitive and brain changes that may predispose individuals to develop dementia later in life. Understanding the pathophysiology of neurodegeneration and identifying preclinical biomarkers for early diagnosis of dementia, especially as measured by neuropsychology and neuroimaging, are fundamental goals for the lab.

Our research uses a variety multimodal neuroimaging types, including PET, sMRI, fMRI, DTI, and integrates genetic, molecular and neuropsychological data to characterize some of the earliest changes associated with dementia.

Our Research

We recently received funding from the National Institute of Health Office of the Director and the National Institute of Aging to investigate memory network dysfunction as an early marker of preclinical Alzheimer’s disease (AD). For this study, we are comparing a Colombian kindred with early-onset AD with a group of asymptomatic older individuals who are participants in the Harvard Aging Brain Study at Massachusetts General Hospital and are considered at high risk through molecular pathology imaging to develop late onset sporadic AD.

  • Yakeel T. Quiroz, PhD


    Dr. Quiroz is assistant professor in the Departments of Psychiatry and Neurology at Massachusetts General Hospital and Harvard Medical School, Boston, MA. She currently serves as director of the Mass General Multicultural Alzheimer’s Prevention Program (MAPP). She completed her PhD in clinical psychology at Boston University and her clinical internship and postdoctoral fellowship in neuropsychology at the Mass General. Dr. Quiroz’s research interests focus on studying the neural underpinnings of memory dysfunction in the preclinical stages of Alzheimer’s disease (AD).

    By applying her efforts to the world’s largest family with a single, early onset AD-causing mutation (E280A in PSEN1), her research has provided evidence of brain abnormalities in individuals at genetic risk for AD decades before their clinical onset. Her findings have helped the field to re-conceptualize Alzheimer’s as a sequence of changes that begins decades before cognitive decline, and which may be targeted by promising disease-slowing treatments at a time in which they might have their most profound effect. Her research work has resulted in several publications that have generated considerable discussion in the field, and has achieved recognition by colleagues at the regional, national, and international level.  Dr. Quiroz is the recipient of several awards, including the NIH Director’s Early Independence Award, the FABBS Foundation Early Career Impact Award, the National Academy of Neuropsychology Tony Wong Diversity Award, and the Exact, Physical and Natural Sciences Prize from the Alejandro Angel Escobar Foundation in Colombia.

    Dr. Quiroz also serves as clinical director of the Multicultural Neuropsychology Program (MUNDOS) at Psychology Assessment Center, and director of the Multicultural Neuropsychology training program. In her spare time she enjoys spending time with her family and friends, traveling to new places and listening to music.

She is passionate about advocating for patients with dementia and their families, promoting healthy brain aging and positive mental health and training the next generation of geriatric psychiatrists and clinician-researchers. In her spare time, she enjoys spending time with family and friends, cooking and sampling cuisines, being amused by her Russian blue cats, Cosmo and Whiskers, and pursuing the most beautiful beaches, near and far.

  • Liliana Ramirez, MD

    Dr. Ramirez Gomez is a neurologist at Mass General and provides clinical service to patients in the Memory Disorders, Comprehensive Neurology and Behavioral Neurology units. Dr. Ramirez Gomez completed medical school at the University of Antioquia in Medellin, Colombia, and neurology residency at the University of Southern California Keck School of Medicine, where she served as chief resident. She completed a fellowship in cognitive and behavioral neurology at the Memory and Aging Center at USC.

    Her work focuses on understanding preclinical and clinical markers of cognitive impairment that may aid in the diagnosis of dementia.  She has elucidated vascular contributions to cognitive impairment and dementia. In collaboration with Dr. Helena Chui at the University of Southern California, she studied how to differentiate among types of dementia using specific neuropsychological tests and neuroimaging.  She has also collaborated with the National Alzheimer Coordinating Centers to identify late vascular risk factors and Alzheimer’s neuropathology in individuals with normal cognition in late life. 

    Her specific goals in the lab are to determine whether changes in the ability to identify and remember odors can serve as a novel specific biomarker for early onset familial AD.  She also aims to understand the relationship between AD neuropathological changes and the onset of sleep disturbance and cognitive decline in preclinical stages of AD, decades before full-blown symptoms begin.  

    She enjoys spending time with family and friends, hiking and relaxing in nature.

Research Projects

Our lab is currently focused on two areas of research:

Preclinical markers of Alzheimer’s disease

The overall goal of this project is to study the impact of amyloid and tau pathology on memory function in preclinical stages of Alzheimer’s disease (AD) and their role in subsequent neuronal death and cognitive decline.

This project leverages our access to two extraordinarily rich preclinical AD groups:

  1. The Colombian kindred with Presenilin 1 E280A mutation
  2. A group of asymptomatic older individuals who are participants in the Harvard Aging Brain Study (HABS) at Mass General and are considered at high risk (by molecular pathology imaging) to develop late-onset sporadic AD

The primary goals of this research are to:

  • Investigate abnormalities of associative-memory processes as a possible cognitive marker of preclinical AD
  • Investigate brain hyper-activity/hyper- connectivity as a marker of early AD pathology
  • Examine the role of tau and amyloid aggregation in memory network dysfunction

Neuroimaging markers for the differential diagnosis of young-onset dementias

This project examines the role of white matter disease and genetic and molecular factors on subtle cognitive decline in preclinical early-onset Alzheimer’s disease, frontotemporal dementia and CADASIL (Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy).
