Dr. Andreas Plaitakis received his M.D. and Ph.D. degree from the University of Athens Greece. He was trained in Internal Medicine and in Neurology at Mount Sinai Hospital, where he also completed his NIH post-doctoral fellowship in Neurochemistry. He then joined the Mount Sinai faculty and rose through the ranks to Professor of Neurology. After working at Mount Sinai for over 20 years, he became Chairman of the Department of Neurology at the newly established University of Crete, where for a decade he also served as Director of the Graduate Program in Neuroscience and as Dean of Graduate studies. Recently, he returned to Mount Sinai joining again the Neurology faculty.
Dr. Plaitakis has been the principal investigator of research projects funded by NIH for almost two decades. He has published over 150 original articles and book chapters, and two textbooks. He has been an invited speaker at many National and International Meetings. He is an elected member of the American Neurologic Association.
Dr. Plaitakis divides his time between Clinical Neurology and Basic Research. He has made original observations that linked metabolic abnormalities to human degenerative neurological disorders (Plaitakis, et al. Science, 1982). His observations on glutamate alterations in Amyotrophic Lateral Sclerosis was rationale behind the use of Riluzole, a glutamate-modifying agent, for treating this devastating disorder, the only effective treatment that is currently available.
At the basic Science level, his team cloned and characterized human proteins involved in the metabolism and transport of glutamate, a major excitatory neurotransmitter involved in a multitude of normal brain functions and in neurodegenerative processes. They also elucidated the evolutionary steps by which a novel glutamate-metabolizing enzyme acquired unique properties and a nerve tissue expression profile that may have contributed to traits, such as cognitive function, unique to humans.
Plaitakis also maintains a special interest in the clinical aspects and etio-pathogenesis
of movement disorders (Ataxia, Huntington’s disease, Parkinson’s disease, etc),
dementias and Multiple Sclerosis (MS). He and his co-investigators identified environmental
factors contributing to the rising incidence of MS among females. They also detected
brain hemodynamic changes at the earliest stages of MS that correlate with
cognitive dysfunction. In
addition, he is dedicated to the care of patients with diverse neurologic
conditions that fall within the full spectrum of general neurology.

LATEST PUBLICATIONS (2010-2014)
Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies 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 relationships with such companies.
Dr. Plaitakis did not report having any of the following types of financial relationships with industry during 2014 and/or 2015: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.
Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
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.
