In this "Ask the Expert" episode, Krissy Dilger of SRNA interviewed Dr. Giovanna Manzano about neurosarcoidosis and rare neuroimmune disorders. They explored the definition of neurosarcoidosis, its symptoms, and the diagnostic process, emphasizing the challenges in identifying the condition due to its diverse manifestations. Dr. Manzano delved into the potential causes of neurosarcoidosis, highlighting immune system dysregulation and the formation of granulomas. Treatment options, including steroids and immune suppressants, were discussed, and the chronic nature of the disease was explored, with considerations for relapses and long-term effects. The conversation concluded with insights into patient advocacy, the importance of early diagnosis, and ongoing research efforts in the field. Giovanna S. Manzano, MD is a neuroimmunologist/MS specialist and neurohospitalist at the Massachusetts General Hospital and the Brigham and Women's Hospital in Boston, Massachusetts. She provides care to patients with neuroimmunologic diseases inclusive of CNS demyelinating disorders, autoimmune/paraneoplastic encephalitis and cerebellar degeneration, neurosarcoidosis, and neurotoxicities from oncologic therapies. Her research is focused on optimizing care delivery and approach to treatment of neuroimmunologic conditions by way of studies that emphasize patient reported outcomes, quality improvement, and clinical trial design.
