Official title
Neural Correlates of Cognitive Dysfunction in Postural Tachycardia Syndrome
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Postural tachycardia syndrome (POTS) is one of the most common forms of chronic orthostatic intolerance in the United States. This is a disabling disorder characterized by an excessive increase in heart rate upon standing that is accompanied by symptoms such as dizziness and fatigue. One of the most under appreciated and bothersome symptoms of POTS is impaired cognition or "brain fog," which occurs to a level that interferes with daily activities such as work and education. Despite this high impact, the reasons why POTS patients have problems with cognition are not well understood. This project will test the overall hypothesis that "brain fog" in POTS is related to increased activation of cognitive brain regions during mental tasks when compared with healthy subjects, and that this activation is exacerbated by in the presence of orthostatic stress.
