Stanford ADRC Clinical Core

The Clinical Core of the Stanford Alzheimer’s Disease Research Center (ADRC) recruits and follows patients with Alzheimer’s disease, Parkinson’s disease, dementia with Lewy bodies, and mild cognitive impairment; and healthy older volunteers without neurological disease or cognitive impairment.  Information that we collect supports innovative research on understanding fundamental causes of neurodegenerative disease and enabling early identification, effective treatment, and prevention.

We believe that research is most efficient when each volunteer is able to contribute multiple types of information. We refer to this strategy as “deep phenotyping.” Our research data come from neurological and neuropsychological assessments, brain imaging (PET scans and MRI scans), and molecular and genetic markers derived from blood, spinal fluid, skin fibroblasts, and stool.  All of these are ultimately tied to crucial diagnostic information obtained by brain autopsy through the ADRC Neuropathology Core.  Anonymous research data and some specimens and tissues are shared with researchers at Stanford and other universities.  Like other ADRCs, we provide Uniform Data Set measures to the  National Alzheimer’s Coordinating Center (Seattle, WA) and biological specimens to the National Centralized Repository for Alzheimer’s Disease and Related Dementias (Indianapolis, IN).  We maintain strict confidentiality. The Clinical Core is led by Dr. Victor Henderson and Christina Wyss-Coray (Clinical Coordinator) and by Dr. Kathleen Poston (Lewy body disease), Dr. Sharon Sha (clinical trials), and Dr. Maya Yutsis (neuropsychology).

Ami Bhatt, MD, PhD
Assistant Professor, Medicine and Genetics

Humans are now understood to live in complex symbiosis with microbes. While the majority of interactions between the host and microbiota are considered to be symbiotic, alterations of the microbiota are associated with various disease states. It is hypothesized that perhaps the patients most susceptible to adverse outcomes of microbiota dysbiosis are patients whose immune systems are challenged. The goal of the Bhatt lab is to understand the interplay between the microbial environment in immunocompromised patients, especially those with hematological malignancies (leukemia and lymphoma). The laboratory focuses on (1) the use of next generation sequencing to define the microbiome and host immunologic features in patients with hematological diseases and (2) developing custom computational tools for the identification of novel human commensals and pathogens in these immunosuppressed patient populations, and (3) using statistical and functional biological methods to understand the interplay between the human microbiome and the development of immunological diversity.
