Neurocognitive Testing in POTS: A Pilot Study

Summary

The purpose of this study is to determine if POTS patients perform as well as healthy people on tests of cognition (thinking). The results of this study may help us to better understand if POTS patients' complaints of "brain fog" needs to be studied more carefully.

Postural Tachycardia Syndrome (POTS) is a disorder that features an inappropriate increase in heart rate upon standing in addition to chronic symptoms including lightheadedness, dizziness, mental clouding, and palpitations.

A common complaint among people with POTS is “brain fog” – a difficulty in concentrating. We are trying to learn more about this “brain fog”. To do this we are are conducting some tests of brain function (on paper and on computer). We are also measuring heart rates and blood pressures while lying down and standing up.
