Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include individuals aged 18 to 60 with a diagnosis of Long COVID or POTS who experience cognitive dysfunction.
✕Probably not a fit
Patients with overt causes for POTS or those unable to provide informed consent may not benefit from this study.

What this trial studies
This study investigates the effects of intravenous (IV) saline on cognitive dysfunction in patients diagnosed with Postural Orthostatic Tachycardia Syndrome (POTS) and Post-Acute Sequelae of COVID (Long COVID). Participants will receive either a 999 mL infusion of normal saline or a placebo of 50 mL saline to assess improvements in cognitive function, specifically targeting symptoms like brain fog and mental fatigue. The study aims to provide initial insights into the neurocognitive impairments associated with these conditions and evaluate the potential therapeutic role of saline infusions. By comparing cognitive performance before and after treatment, the researchers hope to establish a foundation for future studies on underlying mechanisms and treatments.
Why it matters
Potential benefit: If successful, this study could lead to improved cognitive function and quality of life for patients suffering from POTS and Long COVID.
How similar studies have gone: While there is limited research specifically on saline infusions for cognitive dysfunction in these populations, the study's approach is novel and aims to fill a significant gap in understanding.
