About Brett Morrison
Primary Academic Title
Associate Professor of Neurology
Background
Dr. Brett Morrison specializes in neuromuscular disorders in adults including peripheral neuropathies, amyotrophic lateral sclerosis, myasthenia gravis and muscle diseases.
Dr. Morrison is currently the site principal investigator for clinical trials investigating new treatments for chronic inflammatory demyelinating polyneuropathy (CIDP) and painful diabetic peripheral neuropathy.
Dr. Morrison's research interests include investigations into the mechanisms of nerve regeneration and common peripheral neuropathies. Current research focuses on better understanding the role of the immune system in peripheral nerves and targeting these pathways for the development of new treatments.
Dr. Brett Morrison received his M.D. and Ph.D. from Mount Sinai Medical School in New York City. He completed his medical internship at the University of Maryland and residency in neurology at The Johns Hopkins Hospital. He then completed a fellowship in Clinical Neurophysiology at The Johns Hopkins Hospital.

Provider was good

Dr. Morrison is definitely top notch. He really cares about my health. I'm definitely not just a random patient. I have a problem with my pancreas, he's the doctor that diagnosed it. He did a follow up to see if I was able to get the meds. He also addressed my nerve pain and added a med. He listens better than most doctors.

Providers are the best. The nurse that took my vitals made me late for my appointment.

I was pleased with my first appointment. The doctor asked questions; he listened; he examined my legs and feet; he was thorough; he added a prescription that will hopefully be helpful to my feet. He ordered blood work and an EMG. He will talk with me in two weeks after going over the collected information.

- 5 out of 5 starsReviewed on 4/23/2024
Professional but was able to relate to my concerns. Very appreciative of the time he spent with me. Too many providers are on a 15 minute clock and do not spend adequate time with me. He listened and physically checked my health status.
