Behavioral Neurology and Neuropsychiatry Fellowship at The Mount Sinai Hospital

The Behavioral Neurology and Neuropsychiatry Fellowship at The Mount Sinai Hospital is a one-year program accredited by the United Council for Neurological Subspecialties. Fellows receive clinical training in the assessment and management of behavioral neurology and neuropsychiatry disorders. Our faculty and program director are dedicated to fellows’ success, as reinforced in our one-on-one mentorship program, which supports fellows on patient care, career development, and research.

Based in the Estelle and Daniel Maggin Department of Neurology at the Icahn School of Medicine at Mount Sinai—the oldest neurology department in the United States—the fellowship offers a vast array of clinical, educational, and research opportunities that prepare fellows for advanced practice in this specialized field. Following completion of our program, fellows are eligible to apply for the certification examination by the United Council of Neurologic Subspecialties in Behavioral Neurology and Neuropsychiatry.

Meet the Director

Our fellowship offers comprehensive training in advanced behavioral neurology and neuropsychiatry. Fellows gain hands-on experience with innovative diagnostic and treatment approaches, including neuropsychological testing, advanced neuroimaging, neuropathology, the use and interpretation of biomarkers, and the administration of monoclonal antibody treatments. The Barbara and Maurice Deane Center for Wellness and Cognitive Health, one of the locations where our fellows train, provides access to multidisciplinary training alongside experts in behavioral neurology, geriatric psychiatry, geriatric medicine, neuropsychology, and additional related fields.

During weekly assigned clinic time, our fellows care for patients with a broad spectrum of cognitive and behavioral conditions, including Alzheimer’s disease and related dementias, Lewy body disease, vascular disease and frontotemporal dementia (behavioral variants and primary progressive aphasias), among others. Clinical training also includes the evaluation and management of the cognitive and behavioral effects of epilepsy, movement disorders, stroke, traumatic brain injury, and other non-degenerative neurological conditions. Optional additional clinical training is available during ad-hoc clinics staffed by an attending, designed for fellows interested in additional clinical exposure.

Throughout the fellowship, trainees also receive training and evaluate patients that are participating in the National Institute on Aging-Designated Alzheimer's Disease Research Center. Our trainees also engage in participation in patient research evaluations within the Mount Sinai ALL-Frontotemporal Lobar Degeneration Research Study, which offers national-scope research opportunities in frontotemporal lobar degeneration.

As part of curated monthly training experiences, fellows rotate across multiple services, including:

  • Geriatric psychiatry/consultation liaison psychiatry
  • Geriatric medicine/palliative care
  • Movement disorders
  • Neurocognitive rehabilitation medicine
  • Neuropathology
  • Neuropsychology
  • Neuroradiology
  • Other neurology or psychiatry subspecialties

In addition, our fellows may participate in in-patient consultations, home visits, education of residents and medical students, and didactic lectures at the rotating divisions. Elective time can be used as protected research time to support the learning of research methodology and early development of a research portfolio. The fellowship is a one-year program. A second year of fellowship may be available on a case-by-case basis, subject to availability and individual career development.

Finally, fellows also meet with the Program Director throughout the fellowship for progress review and mutual feedback.

The Behavioral Neurology and Neuropsychiatry Fellowship offers a wide range of educational opportunities outside of the curriculum, including conferences and didactics. A specific didactic program is created for each fellow depending on the rotation, including:

  • Division and interdisciplinary conferences with patient case presentations and discussions
  • Grand Rounds
  • Neuropsychology and Geriatric Psychiatry Journal Club
  • Movement Disorder Video Conferences
  • Clinicopathologic Conferences

Throughout the course of the fellowship, trainees that are interested in research are encouraged, with faculty support, to pursue individual interests and either develop new research or become involved with current ongoing research. Our physicians work with the Alzheimer's Disease Research Center to conduct clinical research and are engaged in laboratory research to understand the causes of these disorders and develop novel therapies. Each fellow will work on publishing at least one manuscript during their fellowship in a peer-reviewed journal.

We select one-to-two fellows each year. Applicants must have completed an Accreditation Council for Graduate Medical Education-accredited neurology or psychiatry residency program or equivalent and be eligible for licensure in the State of New York.

To apply, please submit the following to Georges Naasan, MD, Program Director, at georges.naasan@mssm.edu, and Geraldine Cera, Program Coordinator, at geraldine.cera@mssm.edu.

  • Application form
  • Curriculum vitae
  • Three letters of recommendation relevant to this training position
  • Personal statement

Applications will be reviewed by the selection committee throughout the year. We strongly recommend fellows send in applications 15-20 months before the intended start date.

“I am honored to be the first fellow to graduate from the Icahn School of Medicine’s Behavioral Neurology and Neuropsychiatry program. Throughout this training, I had the privilege of engaging in a rich array of rotations — including memory disorders, movement disorders, brain injury rehabilitation, epilepsy, neuropathology, neuropsychology, Alzheimer’s research, and complex neuropsychiatric care, while working alongside leading experts in the field. Each experience broadened my clinical expertise, deepened my understanding of the brain-mind connection, and strengthened my commitment to advancing patient care. I am proud to return to the department to serve as faculty.”
