Neurology Department at Westchester Medical Center
The Department of Neurology is comprised of multi-disciplinary teams of clinical experts that provide comprehensive neurological care for a wide range of neurological disorders affecting the brain, spine, nerves, and muscle. The conditions we treat range from neurologic emergencies, such as acute stroke or status epilepticus, to more chronic conditions such as headache/pain syndromes, epilepsy (seizures), neuromuscular (neuropathy, myasthenia gravis, muscular dystrophy), neuroimmunological (multiple sclerosis), as well as neurodegenerative (dementia) and movement disorders (Parkinson’s disease). All divisions are directed by highly qualified sub-specialists.
Compassionate Care and Excellent Outcomes
We seek to provide our patients with compassionate care and excellent outcomes while advancing current standards of care through clinical research. We emphasize effective and open communication with our patients and referring physicians.
Our physicians are supported by dedicated physician assistants, nurse practitioners, registered nurses, therapists, psychologists and social workers. The Neurology Department partners closely with other departments at Westchester Medical Center, including:
- Neurosurgery
- Radiology
- Emergency Medicine
- Internal Medicine
- Psychiatry
- Neuropsychology
- Neuropathology
- Social Work
- Chronic Pain Management.

Subspecialties and Conditions Treated
The following specializations distinguish the Neurology Department at Westchester Medical Center.


The Comprehensive Stroke Center at Westchester Medical Center
We are proud to be the only hospital in New York’s Hudson Valley region recognized by the New York State Department of Health as a Comprehensive Stroke Center.
The Center is dedicated to rapid intervention in the management of acute stroke and to the study of new and effective treatments. Our mission is to provide expeditious care to patients with acute strokes to limit stroke-associated brain damage.
In 2022, the Center earned the prestigious American Heart Association/American Stroke Association's Get with the Guidelines® Stroke Gold Plus Quality Achievement Award as well as the Target: Stroke Honor Roll Elite and Get with the Guidelines Target: Type 2 Diabetes Honor Roll.
The care we provide is multifaceted and our team is comprised of stroke experts such as emergency medicine physicians, vascular neurologists, neurointerventionalists, neuroradiologists, and neurointensivists. Working together, our highly synchronized team strives to facilitate the highest quality care for cerebrovascular disease.
Using advanced rapid diagnostic technology, such as tele-stroke, we can extend our expertise to distant sites miles away. Upon arrival to one of our sites, our RAPID CT perfusion technology allows us to quickly identify patients who are beyond the conventional therapeutic windows for neurointerventions. Finally, WMC is the first site in the country to utilize the FDA approved robotic transcranial doppler monitor for patients with subarachnoid hemorrhage.
