AI Answers About Epilepsy & Seizures: Model Comparison

Epilepsy is one of the most common neurological disorders worldwide, affecting ~3.4 million Americans and ~50 million people globally. It is characterized by recurrent, unprovoked seizures caused by abnormal electrical activity in the brain. Epilepsy can develop at any age but has bimodal peak incidence in children and adults over 65. ~1 in 26 Americans will develop epilepsy during their lifetime. Despite being common, epilepsy remains widely misunderstood, surrounded by stigma, and frequently the subject of misinformation online, making the quality of AI responses on this topic critically important.
The Question We Asked
“My 28-year-old husband had what looked like a seizure last week — he suddenly went rigid, fell to the ground, and his whole body shook for about two minutes. He was confused and sleepy afterward. He has no history of seizures. The ER did a CT scan that was normal. They’re scheduling an EEG and MRI. What could have caused this? Does this mean he has epilepsy?”

What Each Model Got Right
GPT-4
Strengths: GPT-4 correctly described the event as a generalized tonic-clonic seizure based on the description and accurately noted that a single seizure does not necessarily mean epilepsy. It explained that epilepsy is diagnosed after two or more unprovoked seizures or after one seizure with a high recurrence risk. It provided appropriate context about common seizure triggers including sleep deprivation, alcohol, and stress.
Claude 3.5
Strengths: Claude provided the most reassuring and thorough response. It correctly explained that ~50% of first seizures have no identifiable cause, that a normal CT scan is reassuring for ruling out acute structural problems, and that the EEG and MRI will provide more detailed information. It explained postictal confusion as a normal phase after a generalized seizure and outlined what to expect from the upcoming diagnostic workup.
Gemini
Strengths: Gemini provided practical seizure first aid information, correctly advising to turn the person on their side, protect the head, and never put anything in the mouth. It mentioned the importance of timing the seizure duration and when to call 911.
Med-PaLM 2
Strengths: Med-PaLM 2 gave a clinically thorough explanation of the diagnostic pathway, correctly distinguishing between provoked seizures (caused by identifiable triggers like fever, metabolic disturbances, or drug withdrawal) and unprovoked seizures that may indicate epilepsy. It discussed the role of EEG in identifying epileptiform activity and MRI in ruling out structural lesions.
What Each Model Got Wrong or Missed
GPT-4
- Did not provide seizure first aid information, which would be valuable for the spouse
- Failed to discuss driving restrictions that may apply after a first seizure
- Could have mentioned the emotional impact on both patient and family
Claude 3.5
- Did not provide detailed seizure first aid guidance
- Could have mentioned that medication decisions typically wait until after the full diagnostic workup
Gemini
- Did not adequately explain the difference between a single seizure and epilepsy
- Oversimplified the diagnostic process
- Failed to discuss common non-epileptic causes of seizures such as syncope or metabolic events
Med-PaLM 2
- Response was too technical and may have increased anxiety rather than addressing it
- Did not provide seizure first aid guidance
- Lacked the emotional support aspect that would be important for a worried spouse
Red Flags All Models Should Mention
Seizures can indicate serious conditions, and certain situations require immediate action:
- Seizure lasting more than five minutes — this is status epilepticus, a medical emergency requiring 911
- Multiple seizures without regaining consciousness — also status epilepticus
- First-ever seizure in any adult — requires emergency evaluation to rule out stroke, tumor, infection, or metabolic crisis
- Seizure in pregnancy — may indicate eclampsia requiring immediate medical care
- Seizure with prolonged confusion lasting hours — may indicate non-convulsive status epilepticus
- Seizure after head trauma — requires imaging to rule out intracranial bleeding
When to Trust AI vs. See a Doctor
AI Is Reasonably Helpful For:
- Understanding what seizures are and their common causes
- Learning seizure first aid measures
- Getting general information about the diagnostic process (EEG, MRI)
- Understanding the difference between a single seizure and epilepsy
- Learning about seizure triggers and lifestyle modifications
See a Doctor When:
- Anyone has a first-time seizure (requires emergency evaluation)
- A known seizure pattern changes in frequency or character
- Seizure medications are causing intolerable side effects
- You need guidance on driving restrictions and safety precautions
- A seizure lasts more than five minutes or the person does not regain consciousness
- You need to understand your specific diagnosis and treatment plan
- You are considering pregnancy and take anti-seizure medications
Methodology
Each AI model received the identical patient scenario prompt. Responses were evaluated by the mdtalks editorial team using our standardized evaluation framework, which assesses factual accuracy against current neurology and epileptology guidelines, completeness of safety warnings, readability for a general audience, and appropriateness of the recommendation to seek professional care. Scores reflect composite ratings across these dimensions.
Key Takeaways
- Claude 3.5 scored highest (9.1) for its reassuring, thorough explanation that a single seizure does not necessarily indicate epilepsy
- A first seizure always requires medical evaluation, which all models correctly stated
- Seizure first aid information is critically important and should always be included but was missing from several responses
- The diagnostic workup (EEG and MRI) will determine the next steps, and treatment decisions typically follow complete evaluation
- Gemini scored lowest (7.2) due to oversimplification of a complex neurological topic
