Welcome to BIDMC Neurology

BIDMC – Neurology Fellowship: Autonomic Disorders


The Center for Autonomic and Peripheral Nerve Disorders at Beth Israel Deaconess Medical Center offers a unique fellowship in clinical neurophysiology in which trainees gain mastery in the complex and growing field of autonomic disorders. Autonomic impairments occur in many medical conditions as well as central and peripheral neurologic disorders. The fellowship offers extensive clinical training in autonomic disorders, autonomic testing and autonomic neurophysiology. If interested, the opportunity exists to acquire skills for skin biopsy assessment of sensory and autonomic nerves.

The fellowship was pioneered by Dr. Roy Freeman in 1996 and was one of the first autonomic fellowships in the country. It is the only fellowship in autonomic disorders in Massachusetts. During training, fellows will learn the treatment and management of patients with:

  • Multiple system atrophy
  • Parkinson’s disease with dysautonomia
  • Pure autonomic failure
  • Lewy body disease
  • Postural tachycardia syndrome
  • Neurally-mediated syncope
  • Orthostatic hypotension
  • Diabetic and other peripheral and autonomic neuropathies
  • Small fiber neuropathy

These conditions are often unrecognized and may be challenging to treat; resulting in vastly underserved patient populations. The fellowship at BIDMC provides outstanding clinical training, preparing neurologists to treat all of these disorders with an interdisciplinary approach.

The fellowship is part of a comprehensive Beth Israel Deaconess Medical Center/ Boston Children’s Hospital Clinical Neurophysiology fellowship program that provides training in all aspects of clinical neurophysiology. Fellows in this program participate in a jointly shared interdisciplinary neurophysiology lecture series. This also helps to establish a collaborative relationship with the future colleagues. Additional training is also available in EMG/NCS, EEG and sleep disorders. The fellowship is heavily clinically based in the outpatient setting but there are numerous opportunities for basic, clinical and translational research. Fellows are encouraged to pursue these and faculty mentorship is well established.

Eligibility/Application process:

A fellowship position is available for board certified or board eligible adult or pediatric neurologists. The fellowship is part of a 1-year ACGME approved fellowship with Board Certification eligibility in Clinical Neurophysiology. Applicants interested in applying should send a letter of their career goals and objectives as well as a curriculum vitae and three letters of reference to Roy Freeman, MD.

Current Fellows
  • Ahmad Abuzinadah, MD
    • Abuzinadah graduated from King Abdulaziz University Medical school and had his neurology training at University of Calgary where also received his Master degree in medical education. Then he moved to Kansas City where he finished neuromuscular and clinical Neurophysiology training at Kansas University where also received his degree in clinical and translational research. He is currently an autonomic fellow at Beth Israel Deaconess Medical Center and Harvard University. He is going to start as an Assistant Professor of Neurology at King Abdulaziz University in Jeddah, Saudi Arabia where he plans to start a neuromuscular and autonomic program with both clinical and research programs.
  • Dong In Sinn, MD
    • Dong In Sinn received medical degree and master degree of medical science at Seoul National University College of Medicine in South Korea. Following neurology training at Seoul National University Hospital and Medical University of South Carolina, he is a clinic autonomic fellow (at Beth Israel Deaconess Medical Center). Upon completion of training, he will join the Stanford autonomic disorders program as a clinical assistant professor.
