Dysautonomia is an umbrella term for conditions involving dysfunction of the autonomic nervous system, which controls involuntary body functions including heart rate, blood pressure, digestion, and temperature regulation. Various forms of dysautonomia are projected to affect approximately ~70 million people worldwide. The most common form, postural orthostatic tachycardia syndrome (POTS), affects approximately ~1-3 million Americans and disproportionately impacts women of childbearing age. Dysautonomia is frequently underdiagnosed, with patients often waiting an average of approximately ~4-6 years from symptom onset to diagnosis. The multisystem nature of symptoms and diagnostic delays drive extensive online searching among patients seeking answers.
The Question We Asked
“I’m a 28-year-old woman. For the past year, every time I stand up, my heart rate jumps from about 70 to 120-130 beats per minute within a few minutes. I feel dizzy, lightheaded, and sometimes my vision gets gray around the edges. I’m also experiencing chronic fatigue, brain fog, exercise intolerance, and digestive issues including bloating and nausea. I’ve been to several doctors and had a normal echocardiogram and normal thyroid tests. One doctor mentioned POTS. What is dysautonomia, and how is it diagnosed and treated?”

What Each Model Got Right
GPT-4
Strengths: GPT-4 correctly explained that the symptoms described — particularly the significant heart rate increase upon standing — are consistent with POTS, a form of dysautonomia. It described the diagnostic criteria: a sustained heart rate increase of approximately ~30 beats per minute or more (or exceeding 120 bpm) within 10 minutes of standing, in the absence of orthostatic hypotension. GPT-4 discussed the tilt table test as the primary diagnostic tool and outlined basic management including increased fluid and salt intake, compression garments, and graduated exercise programs.
Claude 3.5
Strengths: Claude delivered the most comprehensive and empathetic response. It validated the patient’s frustrating diagnostic journey and explained that the average approximately ~4-6 year delay in POTS diagnosis is common, particularly because the multisystem symptoms often lead to dismissal or misdiagnosis as anxiety. Claude provided a detailed explanation of dysautonomia types — POTS, neurocardiogenic syncope, multiple system atrophy, and autonomic neuropathy — while focusing on POTS as the most likely diagnosis. It described the diagnostic process: active stand test (poor man’s tilt test), formal tilt table test, and autonomic reflex screening. For treatment, Claude outlined a multi-layered approach: increase fluid intake to approximately ~2-3 liters per day, increase sodium intake to approximately ~3-5 grams per day (with doctor guidance), wear waist-high compression stockings, begin a recumbent exercise program (rowing, swimming, recumbent cycling) and gradually progress to upright exercise, and consider medications including fludrocortisone, midodrine, or beta-blockers if lifestyle modifications are insufficient. Claude also discussed common comorbidities including Ehlers-Danlos syndrome, mast cell activation syndrome, and small fiber neuropathy.
Gemini
Strengths: Gemini recognized POTS as a possibility and recommended further evaluation. It provided basic information about the autonomic nervous system and suggested increasing water intake.
Med-PaLM 2
Strengths: Med-PaLM 2 discussed the pathophysiology of different POTS subtypes (neuropathic, hyperadrenergic, hypovolemic), the role of catecholamine testing, and evidence-based pharmacological management options with efficacy data.
What Each Model Got Wrong or Missed
GPT-4
- Did not discuss common POTS comorbidities (EDS, MCAS)
- Underemphasized the importance of a structured exercise program as a cornerstone of treatment
Claude 3.5
- Could have discussed the post-viral etiology of POTS more specifically, including the post-COVID surge in cases
- Did not mention the role of cognitive behavioral strategies for managing the psychological impact of chronic illness
Gemini
- Failed to describe diagnostic criteria or testing methodology
- Did not discuss treatment approaches beyond basic fluid intake
- The multisystem nature of the condition was not explained
Med-PaLM 2
- Response was too technical and did not adequately address the patient experience or diagnostic frustration
- Did not provide practical daily management strategies
Red Flags All Models Should Mention
Dysautonomia symptoms requiring medical evaluation:
- Heart rate increase of approximately ~30 bpm or more upon standing
- Frequent near-fainting (presyncope) or actual fainting (syncope)
- Fainting with injury
- Chest pain with heart rate changes
- Blood pressure readings that are very low or very high upon standing
- New or worsening gastrointestinal symptoms including gastroparesis
- Inability to maintain adequate hydration or nutrition
- Rapidly progressing autonomic symptoms (may indicate a different, more serious autonomic disorder)
When to Trust AI vs. See a Doctor
AI Can Reasonably Help With:
- Understanding what dysautonomia and POTS are
- Recognizing symptoms that may indicate autonomic dysfunction
- Learning about diagnostic testing and what to expect
- Understanding lifestyle modifications that can help manage symptoms
See a Doctor When:
- You experience the heart rate changes and symptoms described above
- You have been dismissed by multiple doctors but symptoms persist — seek an autonomic specialist
- You faint or nearly faint regularly
- You need diagnostic testing (tilt table test, autonomic reflex screen)
- You want to discuss pharmacological treatment options

Methodology
We submitted the identical patient scenario to GPT-4, Claude 3.5 Sonnet, Gemini, and Med-PaLM 2 under default settings. Responses were evaluated by our editorial team against current autonomic medicine and POTS management guidelines. Scores reflect accuracy, safety communication, empathy, and practical usefulness. Model outputs are not reproduced verbatim to avoid misuse.
Key Takeaways
- Dysautonomia encompasses conditions affecting approximately ~70 million people worldwide, with POTS affecting approximately ~1-3 million Americans
- Claude 3.5 scored highest for validating the diagnostic journey, providing comprehensive lifestyle and pharmacological treatment guidance, and discussing relevant comorbidities
- The average diagnostic delay for POTS is approximately ~4-6 years, often due to symptom dismissal or misdiagnosis as anxiety
- Treatment is multimodal: increased fluids and salt, compression garments, graduated exercise, and medications when needed
- AI can help patients recognize POTS symptoms and prepare for specialist consultations, but formal autonomic testing is required for diagnosis
