Faria Amjad, MD

Dr. Faria Amjad is director of the Spasticity Clinic at MedStar Georgetown where she manages spasticity affecting the upper or lower extremities using medications, botulinum toxin and intrathecal baclofen pumps. She is also the director of clinical trials involving autoimmune disorders affecting the nervous system.

Board-certified in neurology, Dr. Amjad completed her undergraduate degree, medical degree, neurology residency and fellowship in multiple sclerosis all at Georgetown. During her two-year multiple sclerosis fellowship, Dr. Amjad focused on how to diagnose and manage patients with MS and other autoimmune disorders affecting the nervous system.

Given her long standing affiliation with Georgetown and its core values of service, Dr. Amjad hopes to use her medical training and knowledge to make a meaningful impact on the lives of patients and their families affected with multiple sclerosis. She feels fortunate to practice at a time when physicians have so much hope to offer patients with multiple sclerosis a disease that is chronic and can be debilitating in terms of therapeutics and alternative medicine.
