What Is Dysautonomia / POTS?
Dysautonomia refers to a group of conditions in which the autonomic nervous system (ANS) does not function properly. This system controls automatic body functions such as heart rate, blood pressure, and digestion.
Postural Orthostatic Tachycardia Syndrome (POTS) is one of the most common forms of dysautonomia. It is characterized by:
Rapid heart rate when standing up

Dizziness or fainting
Chronic fatigue and brain fog
Exercise intolerance
Dysautonomia and POTS can be misdiagnosed for years. At CNS Center, we use precise testing methods to uncover the root cause of your symptoms and create an individualized treatment plan.
How We Test for Dysautonomia and POTS at CNS Center
Our neurology-led team performs comprehensive autonomic testing in our Chicago office:
Tilt Table Testing
Evaluates heart rate and blood pressure response to changes in posture, a gold standard test for diagnosing POTS
QSART (Quantitative Sudomotor Axon Reflex Test)
Measures sweat gland function to assess small fiber nerve and autonomic function.
Bloodwork & Laboratory Testing
Identifies underlying causes such as vitamin deficiencies, autoimmune disorders, or hormonal imbalances.
Neurological Evaluation
A thorough exam by Dr. Cohen to assess brain and nervous system function.
By combining these diagnostic tools, we can differentiate between POTS, other autonomic disorders, and neurological conditions that may mimic their symptoms.
