About Me
Dr. Dushyant Purohit is a clinical and academic neuropathologist working as attending neuropathologist and holding a position of Associate Professor of Pathology and Psychiatry at Icahn School of Medicine at Mount Sinai. His research work on dementia had spanned for almost 30 years at Mount Sinai while working on multiple NIH grant-funded programs where he contributed in neuropathological characterization, clinicopathological correlation and phenotypic research on Alzheimer’s disease, movement disorders, ALS-Parkinson-dementia complex of Guam, schizophrenia and brain aging. He also carries out clinical diagnostic work in neuropathology in the Department of Pathology at Mount Sinai. Dr. Purohit offers teaching in the department’s Neuropathology Fellowship program providing 2-year training to two Fellows and to pathology residents and medical students.
Research on dementia and other neurodegenerative disorders: Just when Alzheimer’s Disease Research Center started, Dr. Purohit had joined Dr. Daniel Perl in developing Neuropathology Core of the Mount Sinai ADRC as also in comprehensive neuropathology research support to studies on neurodegenerative disorders under NIH-grant funded research programs including studies on brain aging, ALS-PD complex of Guam, schizophrenia and neurobiological research under the Conte Center program at Mount Sinai. Several studies attributed to Dr. Purohit’s research work included correlation of lesion loads of amyloid plaques, neurofibrillary tangles and Lewy bodies with levels of cognitive impairment, correlation of the risk factors of Alzheimer’s disease, (diabetes, hypertension, vascular injury, depression), studies on movement disorders, and brain changes in schizophrenia, ALS-PDC of Guam, traumatic brain injury and age-related cognitive loss in India. Dr. Purohit has also been providing data and consultation to NACC (National Alzheimer Center Consortium) and had participated in the CERAD group (1990). He participated in study sections for NIH grants.
Brain Banking: Dr. Purohit’s work in neuropathology research led him to engage in brain banking. In Mount Sinai/VA Neurodegenerative Disorders Brain Bank where over 2000 brain specimens have been banked as snapped frozen and formalin fixed specimens, and samples for molecular studies. This activity has recently morphed into a NIH NeuroBioBank center (2013- current), one of the six Brain Banking sites of the NIH directed and managed consortium that aims to make available to neuroscience researchers an unprecedented volume and varieties of brain tissue and other material in Sinai and in centers across the US and internationally. Recently a Mount Sinai for Neurodegenerative Disorders Brain Bank (NDBB) and Research Neuropathology Core established jointly in the Department of Pathology and the Friedman Brain Institute. Dr. Purohit participates as Co-Director for this newly established brain Bank. This endeavor has an additional focus on advancing neuroscience and clinical research by adopting the newer research and archival methods using digital pathology and machine learning.
Research development in the Low and Middle Income Countries: Dr. Purohit’s interest in dementia in developing countries led to his work as Principal Investigator for NIH-grant funded studies on cognitive loss in Indian population (years 2004-2012). This interest stems from his observation that in India, a typical LMIC, where apart from a few illustrious centers, dementia research has been very sparse. His attempt to set up research on dementia in India materialized when he was awarded R21 grant in 2004, and later a follow up R01, by NIH/Fogarty international Center. He is hoping to assist in similar future research programs. He has participated in WHO/WFN/IBRO cosponsored research symposia on dementia in developing countries held in Nairobi that are organized by Institute of Aging of Newcastle University in the UK

Research
The Neuropathology Laboratory and Brain Bank for Neurodegenerative Disorders provide neuropathology support to several federally funded grants for research projects on Alzheimer's disease, Parkinson disease and allied neurodegenerative diseases, and schizophrenia. The laboratory also offers specialized diagnostic reference facility for neurodegenerative disorders. The fully equipped laboratory conducts detailed descriptive studies to document the extent and distribution of various neuropathologic lesions in human brains obtained at autopsy from patients affected by a wide range of neurodegenerative diseases. The resulting characterization of morphologic lesions, diagnosis and clinicopathological correlation of the longitudinally studied cases become an integral part of several grant funded research studies. Our laboratory also has an extensive repository of study material of parkinsonism dementia complex (PDC) of Guam and the recently observed overlap of Alzheimer's disease in the Chamorro, the native inhabitants of Guam and other Marianas islands. Our study also involves the extent of overlap between morphologic changes encountered in other more common neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease and allied movement disorders, Lewy body dementia, vascular dementia and variants of frontal lobe degeneration. Recently, we have focused our research activity on age-related cognitive disorders in the population of developing countries (or low and middle-income countries, as defined by the World Bank Survey of world economies) under a federally funded clinical and pathologic study on dementia and ageing in India and carry out necessary research capacity building there.
Insurance Information
Physicians who provide services at hospitals and facilities in the Mount Sinai Health System might not participate in the same health plans as those Mount Sinai hospitals and facilities (even if the physicians are employed or contracted by those hospitals or facilities).
Information regarding insurance participation and billing by this physician may be found on this page, and can also be obtained by contacting this provider directly. Because physicians insurance participation can change, the insurance information on this page may not always be up-to-date. Please contact this physician directly to obtain the most up-to-date insurance information.
Insurance and health plan networks that the various Mount Sinai Health System hospitals and facilities participate in can be found on the Mount Sinai Health System website.

Industry Relationships
Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device, biotechnology companies, and other outside entities to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their outside financial relationships.
