PIA Executive Committee:

Vascular Cognitive Disorders

 

Chair: Atticus Hainsworth, PhD 

I am a translational scientist working on cerebral small vessel disease and vascular contributions to cognitive impairment and dementia (VCID).


I am currently Reader in Cerebrovascular Disease at St George’s University of London. My first degree is from Cambridge (1985) and my PhD from Rush Medical Center, Chicago (1989). I have extensive experience of  neuropathology and in vivo experimental studies. I am Chief Investigator on the PASTIS trial, testing tadalafil for possible re-purposing in dementia. My long-term research goals are to understand the pathogenesis of small vessel disease, and to see a drug for in clinical use for vascular cognitive impairment.


I have been involved with the Vascular PIA for the past 7 years. Initially my role was to submit reports from other conferences for communication to V-PIA members. I have convened and chaired vascular sessions at AAIC 2015 and AAIC 2016 (with Donna Wilcock), at AAIC 2017 (with Eric Smith) and at AAIC 2019 (with Julie Schneider). I was elected Vice Chair of the Vascular PIA in 2017 and became Chair in July 2019. My goals for the vascular PIA are to
1. Engage the wider PIA membership, in particular reaching out to junior colleagues as the research leaders of the future;
2. Encourage more frequent contact across the PIA membership worldwide, via teleconference, webinars, Skype, WhatsApp and social media (my Twitter name is @AtticHains);
3. Activate the role of pharma industry in VCI. 

 

Vice Chair: Fanny Elahi, MD, PhD
Fanny Elahi is a clinician-scientist with training in neurology, fellowship in neurodegenerative disorders, and doctorate in neurogenetics. She is an Assistant Professor of Neurology at the University of California, San Francisco, Memory and Aging Center, where she evaluates and treats patients with brain degenerative disorders and conducts research on vascular contributions to cognitive impairment and dementia.

The Elahi lab uses a multi-modal approach, combining fluid biomarkers, deep clinical phenotyping, with brain and retinal imaging to investigate immuno-vascular contributions to neurodegenerative disease. A special emphasis of the lab is on the development of novel plasma and exosome-based biomarkers for vascular cognitive impairment and dementia (VCID). The goal is to improve diagnostic accuracy and capture early disease stages when therapies are most impactful. A set of exosome-based biomarkers for immuno-vascular dysregulation are currently being validated in MarkVCID, the NIH/NINDS funded consortium for the discovery of biomarkers of VCID, with the goal of developing clinical trial-ready biomarkers for VCID. 

Work in the Elahi lab is driven by the perspective that impactful discoveries and therapeutic interventions will emerge from synergistic expertise across academic disciplines and industry. Therefore, in light of the highly interdisciplinary nature of VCID research and the critical importance of validation of biomarkers, the Elahi lab partakes in multi-site studies and works closely with industry partners to develop new tools for more accurate quantification of disease and improved understanding of therapeutically targetable pathways in VCID.


Programs Chair: Claudia Satizabal, PhD
Claudia Satizabal is an Assistant Professor at the University of Texas Health Science Center and the Alzheimer’s Biggs Institute in San Antonio, and a Framingham Heart Study investigator. She has a broad interest to uncover the life-course and genetic factors influencing stroke, cognitive decline, and dementia. Her research has explored the role of circulating inflammatory markers, growth factors, and fatty acids in the burden of covert cerebrovascular disease and stroke, and dementia trends. As part of the MarkVCID consortium, she is actively involved in the identification and validation of biomarkers for vascular cognitive impairment and dementia. Claudia is part of several national and international collaborations to identify genetic determinants for stroke, neuroimaging markers of brain aging and small vessel disease, and dementia. Prior to joining the Biggs Institute, Claudia spent five years at Boston University where she started as a post-doc. She obtained a doctoral degree in Neuro-Epidemiology from the Pierre and Marie Curie University in Paris, and a Master’s degree in Epidemiology from Utrecht University.

 

Communications Chair: Whitney Wharton, PhD
I am a cognitive neuroscientist and clinical Investigator with expertise in the influence vascular risk factors and preclinical AD biomarkers in ‘at risk’ populations including individuals with a family history of AD, women, African Americans and the LGBT community. My research aims to understand the mechanisms that contribute to AD risk, in individuals most likely to be affected by AD directly via brain changes, and also individuals caring for those affected by AD. Toward this end, I design mechanism driven - lifestyle and pharmaceutical interventions targeting modifiable risk factors, in hopes of reducing AD risk factors, via novel interventions (art, Tango dance, hormone therapy, repurposing antihypertensives, adapting existing educational interventions to be applicable to underserved communities). Most studies enroll only, or an overrepresentation of African American women. I was a recipient of the NIA K01 Career Development award, which showed different AD biomarker levels (t-tau and ptau) as well as CSF and peripheral inflammation between middle-age, African Americans and whites with a parental history of AD and recently was awarded another R01, which will expand on our existing cohorts and biobanks of CSF, blood, and collect cognitive and sleep data over 2 years, in African American and white women with a parental history of AD. I have ample experience and expertise in enrolling underrepresented and minority populations into clinical research involving lumbar punctures, MRI and study medications. I am the Co-Leader of the Emory ADRC ORE Core and Co-Investigator of the Emory ADRC Minority Engagement Core (MEC).

Suvarna Alladi, Professor of Neurology, National Institute of Mental Health and Neurosciences, Bengaluru, India specialises in cognitive and behavioural neurology. Developing strategies to reduce burden of dementia due to stroke and neurodegenerative disease are priority areas of interest, especially in the context of a developing country like India. Her research includes studying dementia in populations characterized by socio-economic, educational and linguistic diversity. Her research group has adapted and harmonized cognitive tests across different Indian languages for diagnosis of vascular cognitive impairment. She established one of the first Memory clinics in India that works closely with a large Stroke registry and has demonstrated the pattern of vascular dementia in Indian context. Dr Alladi’s group also studies a longitudinal community cohort of elderly to explore the protective impact of lifetime experiences such as education, bilingualism, diet and physical activity on dementia using multi-modality evaluation. She co-founded the NGO- Alzheimer’s and Related Disorders Society of India, Hyderabad-Deccan that is committed to creating awareness about dementia and aims to develop meaningful models of care in Indian context. She has authored several publications in the field of dementia and stroke in journals that include Brain, Neurology, Stroke, Neuropsychologia and others.
