What Researchers Did
This study reviewed current concepts regarding the pathophysiology, prevalence, and treatment of long COVID-19 brain fog and postural orthostatic tachycardia syndrome (POTS).
What They Found
Researchers found that post-COVID-19 cognitive dysfunction affects 10% to 88% of patients, while the prevalence of long COVID-19 postural orthostatic tachycardia syndrome (POTS) remains unknown due to diagnostic variability. The underlying pathophysiology is likely multifactorial, involving immune dysregulation and microvascular dysfunction, with treatments largely supportive and offering marginal benefits for brain fog and symptom reduction for POTS.
Canadian Relevance
This study does not have a direct Canadian connection as it was not conducted in Canada, nor does it specifically reference Canadian data or populations.
Study Limitations
A significant limitation noted is the unknown prevalence of long COVID-19 postural orthostatic tachycardia syndrome due to referral bias and inconsistent definitions.
