ACTRIMS 2023 | Infectious mimickers of MS

Lorna Galleguillos, MD, Clínica Alemana de Santiago, Vitacura, Chile, discusses infectious mimickers of multiple sclerosis (MS). Some infectious diseases most commonly mistaken for MS include Lyme disease, Human T-cell lymphotropic virus-1 (HTLV-1), and syphilis. A proper diagnostic evaluation of suspected cases of MS should consist of a detailed clinical history of infections, vaccines, and physical exam, particularly any skin alterations or lesions, to facilitate the correct differential diagnosis. Laboratory tests can also help distinguish MS from infectious mimickers. Identifying typical MS lesions on magnetic resonance imaging (MRI) is crucial in ruling out other possible diagnoses. This interview took place at the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum 2023 in San Diego, CA.
