Cognitive Dysfunction in Postural Tachycardia Syndrome

This study provides evidence for deficits in selective attention and cognitive processing in patients with POTS, in the seated position when orthostatic stress is minimized. In contrast, other measures of cognitive function including memory assessments were not impaired in these patients, suggesting selectivity in these deficits. These findings provide new insight into the profile of cognitive dysfunction in POTS, and provide the basis for further studies to identify clinical strategies to better manage the mental clouding associated with this condition.
