Dr. Stacey L. Clardy MD PHD FAAN is both clinical and research faculty in the Division of Neuroimmunology within the Department of Neurology, as well as a Neurologist at the Staff Salt Lake City Veterans Affairs Health System, and a consultant at Primary Children’s Hospital. She holds an adjunct appointment in Population Health Sciences.

She established the Autoimmune Neurology Clinic at the University of Utah—one of just a few clinics in the United States focused on serving this group of patients, and the program houses the largest group of both pediatric and adult Autoimmune Neurology Fellowship-trained faculty in the country. Dr. Clardy is also the Founder/Director of the Autoimmune Neurology Fellowship program. Her clinical specialization and research focus is in the field of autoimmune neurology, which encompasses the evaluation and management of both autoimmune and paraneoplastic disorders of the nervous system. The spectrum of autoimmune and paraneoplastic neurological disorders intersects all traditional neurology subspecialties, including movement disorders, epilepsy, behavioral/cognitive, neuromuscular, autonomic, demyelinating, and neuro-oncologic.

Dr. Clardy is currently the principal investigator (PI) of an NIH U01 grant (via the NeuroNEXT Clinical Trials Network) supporting the ExTINGUISH Trial—the first prospective, international, and randomized clinical trial for NMDA receptor encephalitis, at over 37 sites, including 2 European sites, with enrollment ongoing. For more information, see this link.

Dr. Clardy and her mentees have received extramural research funding and competitive scientific awards from the NIH, the Department of Veterans Affairs, the Sumaira Foundation, the Immune Deficiency Foundation, and the Siegel Rare Neuroimmune Association and others.

She is devoted to the care of patients affected by antibody-mediated disorders of the nervous system, both autoimmune and paraneoplastic. Her areas of focus include autoimmune encephalitis, neurosarcoidosis, neuromyelitis optica spectrum disorder (NMOSD), myelin oligodendrocyte glycoprotein antibody disease (MOGAD), stiff-person syndrome, myelopathy/transverse myelitis, and central nervous system complications of rheumatologic disease.

She serves as the Chair of the Autoimmune Neurology Section of the American Academy of Neurology (AAN). She is the current Editor of the Neurology® Podcast and also the Editor of the Neurology Minute™ and a member of the Editorial Board of Neurology: Neuroimmunology & Neuroinflammation, as well as serving on the Publications Committee of the AAN. She is also the director of the biannual Western Intermountain Neurological Organization (WINO) Conference.

Patient Rating

4.8 /5
( out of 42 reviews )

The patient rating score is an average of all responses on our patient experience survey. The rating averages scores for all questions about care from our providers.

The scale on which responses are measured is 1 to 5 with 5 being the best score.

Patient Comments

Patient comments are gathered from our patient experience survey and displayed in their entirety. For the convenience of our visitors, some patient comments have been translated from their original language into English while preserving their original meaning as accurately as possible. Patients are de-identified for confidentiality and patient privacy.

Listened to me and helped me meet my needs to live with my illness in a way I want with the meds I need etc

CLINICAL NEUROSCIENCES CENTER

I honestly feel so fortunate to have been led to Dr. Clardy for my medical care. She is an outstanding provider and is truly at the top of her field. I can't recommend her enough.

CLINICAL NEUROSCIENCES CENTER

I like how Dr. Clardy takes her time with each patient

CLINICAL NEUROSCIENCES CENTER

It is very difficult to get help in the area of my need. Very fortunate to have someone within teach qualified to handle the situation.

CLINICAL NEUROSCIENCES CENTER

Doctor did an excellent job of clearly explaining situation. Suggested materials to learn about diagnosis.

CLINICAL NEUROSCIENCES CENTER

Zoom call with Dr Liu and Dr Clardy. They were very thorough, with pleasant and positive attitudes. I'm truthful about diagnosis and situationAnd expectations.

CLINICAL NEUROSCIENCES CENTER

I tried for 9 months to get answers regarding my health. My husband and I did our own research. We found Doctor Clardy at the U. We encouraged our Family Doctor to make a referral. After waiting several months to get in to her and many, many tests and blood work later, we finally received sone answers. I have been seeing Dr. Clardy since 2016. She has helped me tremendously. I would greatly recommend her for your medical needs.

CLINICAL NEUROSCIENCES CENTER

Dr Clardy, is amazing! She shows Compassion and empathy She's very straightforward with great medical knowledge. I sincerely appreciate her hard work.

CLINICAL NEUROSCIENCES CENTER

DR STACEY CLARDY IS THE VERY BEST. SHE IS EXTREMELY CARING. I TRUST HER COMPLETELY.
