AI Answers About Labyrinthitis: Model Comparison

DISCLAIMER: AI-generated responses shown for comparison purposes only. This is NOT medical advice. Always consult a licensed healthcare professional for medical decisions.

Labyrinthitis is an inner ear infection that causes inflammation of the labyrinth, the structure responsible for both hearing and balance. It affects ~approximately 3.5 per 100,000 people annually and most commonly strikes adults between ages 30 and 60. Viral labyrinthitis, typically following an upper respiratory infection, accounts for the majority of cases. The condition causes sudden, severe vertigo often accompanied by hearing loss and tinnitus, distinguishing it from vestibular neuritis, which affects balance without hearing involvement. While most cases resolve within ~several weeks, ~up to 15 percent of patients experience persistent balance difficulties.

We tested four AI models with a labyrinthitis scenario to evaluate their diagnostic and management guidance.

The Question We Asked

“I’m a 42-year-old man and three days ago I suddenly developed severe spinning dizziness, nausea, and vomiting. The room spins when I move my head. I also notice my hearing seems muffled in my left ear and there’s a ringing sound. I had a cold about a week before this started. Is this vertigo or something more serious? Should I go to the ER?”

What Each Model Got Right

GPT-4

GPT-4 correctly identified labyrinthitis as the most likely diagnosis, distinguishing it from vestibular neuritis by noting the hearing involvement. The model connected the preceding viral illness to the onset and explained the inflammatory process in the inner ear. GPT-4 provided a balanced assessment of urgency, noting that while labyrinthitis itself is not life-threatening, the symptoms overlap with stroke and other serious conditions that require emergency evaluation. The model discussed treatment including vestibular suppressants, antiemetics, and, if bacterial etiology is suspected, antibiotics.

Claude 3.5

Claude 3.5 delivered the most thoughtfully structured response, clearly addressing the patient’s two explicit questions about whether this is “just vertigo” and whether to visit the ER. The model explained that labyrinthitis is a specific cause of vertigo involving both the balance and hearing portions of the inner ear. It correctly recommended medical evaluation rather than waiting at home, noting that acute vertigo with hearing loss warrants assessment to rule out stroke and other causes. Claude 3.5 discussed vestibular rehabilitation therapy as an important component of recovery and set appropriate expectations for the recovery timeline of ~weeks to months.

Gemini

Gemini correctly identified the vestibular system as the source of symptoms and connected the prior cold to the onset. The model provided practical advice for managing acute vertigo at home including lying still during episodes, staying hydrated, and avoiding rapid head movements. Gemini recommended medical evaluation and discussed symptomatic treatment options including meclizine and ondansetron for nausea.

Med-PaLM 2

Med-PaLM 2 provided the most clinically rigorous response, differentiating labyrinthitis from vestibular neuritis, BPPV, Meniere’s disease, and posterior circulation stroke. The model discussed the HINTS examination that clinicians use to distinguish peripheral from central causes of vertigo. Med-PaLM 2 discussed treatment comprehensively, including a short course of vestibular suppressants followed by early vestibular rehabilitation, corticosteroids for inflammation, and audiometric testing to document hearing loss. The model also addressed the small risk of permanent hearing damage.

What Each Model Got Wrong or Missed

GPT-4

GPT-4 did not discuss vestibular rehabilitation therapy, which is the cornerstone of recovery from labyrinthitis. The model focused on acute symptom management without addressing the important recovery and compensation phase. It also did not mention that prolonged use of vestibular suppressants can actually delay central compensation and recovery.

Claude 3.5

Claude 3.5 did not discuss the HINTS examination or other clinical tools that help distinguish peripheral vertigo from central causes like stroke. While it appropriately recommended medical evaluation, it could have explained what danger signs to watch for during the ER visit. The model also did not address audiometric testing.

Gemini

Gemini did not clearly distinguish labyrinthitis from vestibular neuritis and other causes of vertigo, which is a significant diagnostic gap. The model also failed to mention the stroke-mimicking nature of acute vertigo or the importance of ruling out central causes. The hearing loss was insufficiently addressed in both diagnostic and prognostic terms.

Med-PaLM 2

Med-PaLM 2 provided an extensive clinical response that may overwhelm a patient experiencing acute vertigo and anxiety. The practical self-management advice was insufficient. When a patient is actively dizzy and vomiting, immediate coping strategies are as important as clinical information.

Red Flags All Models Should Mention

All AI models should urgently flag these symptoms in the context of acute vertigo:

Vertigo accompanied by severe headache, which may indicate stroke or hemorrhage
Double vision, slurred speech, facial weakness, or limb weakness suggesting a central nervous system event
Inability to walk or stand, particularly with a tendency to fall to one side
Vertigo lasting continuously for more than ~24 hours without any improvement
Sudden, complete hearing loss in one ear, which may require urgent treatment including possible steroid therapy
Fever with vertigo suggesting possible bacterial labyrinthitis requiring antibiotics

When to Trust AI vs. See a Doctor

When AI Information May Be Helpful

AI can help a patient experiencing acute vertigo understand that their symptoms may indicate an inner ear condition rather than something immediately life-threatening, reducing panic while still encouraging medical evaluation. AI can also provide practical tips for managing vertigo symptoms and explain what to expect during medical evaluation.

When You Must See a Doctor

Any new onset of severe vertigo, especially with hearing changes, warrants medical evaluation. A clinician can perform the HINTS examination and other neurological assessments to distinguish inner ear labyrinthitis from stroke and other central causes. Hearing loss associated with labyrinthitis may benefit from early corticosteroid treatment to improve recovery. Vestibular rehabilitation therapy, which is critical for recovery, requires professional guidance. Patients should seek emergency evaluation if vertigo is accompanied by neurological symptoms.

Methodology

We submitted the identical patient scenario to GPT-4, Claude 3.5 Sonnet, Gemini 1.5 Pro, and Med-PaLM 2 in March 2026. Each model received the prompt without prior conversation context. Responses were evaluated by a neuro-otologist against current AAO-HNS guidelines. Models were scored on diagnostic accuracy, urgency assessment, treatment recommendations, and recovery guidance.

Key Takeaways

GPT-4, Claude 3.5, and Med-PaLM 2 correctly identified labyrinthitis and distinguished it from vestibular neuritis based on the hearing involvement, while Gemini failed to make this distinction.
Stroke exclusion was appropriately raised by three of four models, reflecting the critical clinical importance of differentiating peripheral from central vertigo.
Recovery guidance including vestibular rehabilitation was best addressed by Claude 3.5 and Med-PaLM 2, while GPT-4 omitted this important component entirely.
Practical symptom management advice varied widely, with Gemini providing the most useful immediate coping strategies and Med-PaLM 2 providing the least.
Acute vertigo with hearing loss always warrants medical evaluation, and AI should function primarily as a triage guide directing patients to appropriate care.
