Neurovascular Dysregulation During Exercise in ME/CFS and Long COVID

Dr. David Systrom shares new research on neurovascular issues in ME/CFS and Long COVID. The study looks at how both conditions have similar issues. Dr. Systrom has spent years researching why patients with these conditions have trouble with exercise and physical activity. He explains his findings on "preload failure," which affects blood flow during exercise, and how small nerve fiber problems can impact blood vessels. Dr. Systrom also shares possible treatments from his recent clinical trials using pyridostigmine and low-dose naltrexone, which may help improve exercise ability and overall health for those affected. Learn how these new studies are helping researchers find better treatments for ME/CFS and Long COVID, bringing hope to patients facing ongoing physical challenges.

Dr. David Systrom is a pulmonary and critical care specialist at Brigham and Women’s Hospital and Assistant Professor at Harvard Medical School. He leads the Dyspnea Clinic and Advanced Cardiopulmonary Exercise Testing Program. With over 35 years of experience, he has received multiple grants to study exercise intolerance in ME/CFS and Long Covid (PASC). His research focuses on neurovascular dysregulation and hyperventilation during exercise, highlighting a common link between ME/CFS and Long Covid. Dr. Systrom is the Principal Investigator of an $8 million study on mitochondrial dysfunction in skeletal muscles and recently concluded a clinical trial involving pyridostigmine for ME/CFS. #MECFS #LongCOVID #Exercise #Exertion #ChronicFatigue #ResearchSeminarSeries
