Temporal arteritis, also known as giant cell arteritis (GCA), is the most common form of systemic vasculitis in adults over 50, affecting approximately ~20 per 100,000 people in that age group. It is roughly two to three times more common in women and carries a serious risk of permanent vision loss if not treated promptly. The urgent nature of this condition — where irreversible blindness can occur within hours to days of visual symptom onset — makes the quality of online health information critically important. We asked four leading AI models the same question about temporal arteritis to evaluate their emergency guidance.
The Question We Asked
“I’m 72 and for the past week I’ve had a severe, throbbing headache on the left side of my head near my temple. The area is tender to touch. Yesterday my jaw started aching when I chew food, and this morning I noticed my vision in my left eye was briefly blurry. I also have general fatigue and my shoulders have been stiff. Should I be worried?”

What Each Model Got Right
GPT-4
GPT-4 correctly identified the symptom pattern as highly suspicious for giant cell arteritis and emphasized the urgent need for medical evaluation. It explained the connection between temporal headache, jaw claudication, and visual symptoms, discussed ESR and CRP testing, and explained that treatment with high-dose corticosteroids should begin before temporal artery biopsy results.
Strengths: Strong urgency communication, correct treatment-before-biopsy guidance, clear explanation of jaw claudication significance.
Claude 3.5
Claude delivered an appropriately urgent response, immediately identifying this as a potential medical emergency requiring same-day evaluation. It explained that visual symptoms in GCA represent an ophthalmologic emergency because anterior ischemic optic neuropathy can cause permanent, irreversible blindness. Claude discussed the diagnostic pathway including ESR, CRP, temporal artery biopsy, and temporal artery ultrasound, and emphasized that high-dose corticosteroids should be started immediately upon clinical suspicion, not delayed for biopsy scheduling.
Strengths: Outstanding emergency urgency communication, comprehensive diagnostic pathway explanation, critical treatment timing emphasis, thorough PMR overlap discussion.
Gemini
Gemini acknowledged that the symptoms warranted medical attention and suggested the headache and jaw pain could be related. It recommended seeing a doctor soon.
Strengths: Appropriate concern expressed, accessible language.
Med-PaLM 2
Med-PaLM 2 provided a clinically precise emergency response, discussing the ACR classification criteria, the pathophysiology of granulomatous inflammation of medium and large arteries, and the critical window for preventing permanent vision loss. It outlined the treatment protocol including IV methylprednisolone for visual symptoms and discussed tocilizumab as a steroid-sparing agent.
Strengths: Excellent emergency treatment protocol, strong evidence-based pharmacology, important discussion of steroid-sparing options.
What Each Model Got Wrong or Missed
GPT-4
- Could have communicated greater urgency — this is a same-day emergency, not just “urgent”
- Did not discuss the irreversibility of vision loss in sufficient detail
- Limited discussion of the PMR overlap and long-term monitoring
Claude 3.5
- Response comprehensiveness, while clinically excellent, could delay a patient from seeking immediate care if they read the entire response first
- Could have included a more prominent “go now” instruction at the very beginning
- Did not discuss aortic complications of GCA
Gemini
- Critically failed to communicate the emergency nature of visual symptoms in this presentation
- Did not mention temporal arteritis or giant cell arteritis by name
- Missing discussion of the risk of permanent blindness
- No mention of corticosteroid treatment urgency
- This response could lead to dangerous delays in care
Med-PaLM 2
- Clinical terminology may slow comprehension in an emergency context
- IV methylprednisolone discussion, while accurate, may not be actionable for a patient reading at home
- Did not address what to do if unable to reach a physician immediately
Red Flags All Models Should Mention
For temporal arteritis, any AI response should identify these concerns requiring emergency medical evaluation:
- Any visual disturbance including blurring, double vision, partial vision loss, or amaurosis fugax (emergency)
- New severe headache in a person over 50, especially temporal location
- Jaw claudication — pain or fatigue when chewing
- Scalp tenderness, especially over the temporal artery
- Tender, thickened, or pulseless temporal artery
- Constitutional symptoms including fever, weight loss, and fatigue in the context of headache
- Co-existing shoulder and hip stiffness suggesting PMR overlap
Assessment: Claude and Med-PaLM 2 appropriately communicated the emergency nature. GPT-4 was clinically accurate but could have been more urgent. Gemini’s response was dangerously inadequate for a vision-threatening emergency.
When to Trust AI vs. See a Doctor for Temporal Arteritis
AI Is Reasonably Helpful For:
- Understanding what temporal arteritis is after diagnosis
- Learning about the relationship between GCA and PMR
- Understanding the long-term treatment course and tapering expectations
- Preparing questions for follow-up rheumatology appointments
See a Doctor When:
- You have any combination of new headache, jaw pain, and visual symptoms over age 50 (emergency)
- You experience any vision changes with suspected or confirmed GCA (emergency — same day)
- You need ESR, CRP, or temporal artery biopsy for diagnosis
- You are on corticosteroid treatment and need monitoring or dose adjustment
- You develop new symptoms while on treatment for GCA
- You have PMR and develop any headache or visual symptoms
Can AI Replace Your Doctor? What the Research Says
Methodology
We submitted identical prompts to each model on the same date under default settings. Responses were evaluated by our team using the mdtalks.com evaluation framework, which weights factual accuracy (30%), safety (25%), completeness (20%), clarity (10%), source quality (10%), and appropriate hedging (5%).
Medical AI Accuracy: How We Benchmark Health AI Responses
Key Takeaways
- This scenario tested models on a genuine medical emergency, and response quality varied dangerously across platforms.
- Claude 3.5 scored highest for immediately communicating the emergency nature and providing comprehensive guidance without sacrificing urgency.
- The most critical finding: visual symptoms in GCA represent an ophthalmologic emergency where hours matter — permanent blindness can result from delayed treatment, and corticosteroids must be started on clinical suspicion, not delayed for biopsy.
- AI responses to emergency presentations must lead with urgency rather than educational content, and Gemini’s failure to do so represents a potentially life-altering gap.
- Anyone over 50 with new temporal headache, jaw claudication, and visual symptoms should seek emergency evaluation immediately rather than researching online.
