Chronic Epilepsy Management: Epilepsy Diagnosis Confirmed → Classify Seizure Type → Assess Patient Factors → Seizure Type? → Focal Seizure AEDs.
Pathway Overview
15 steps
Algorithm Steps
15 total
01Start 02Action Classify Seizure Type
ILAE 2017 Classification
- Focal onset (aware vs impaired awareness)
- Generalized onset (tonic-clonic, absence, etc.)
- Unknown onset
- Determines AED choice
03Action Assess Patient Factors
Influences AED selection
- Age and sex
- Childbearing potential (teratogenicity)
- Comorbidities (mood, migraine, weight)
- Drug interactions
- Cost and access
04Decision Seizure Type?
Focal vs Generalized
05Action Focal Seizure AEDs
First-line options
- Levetiracetam (broad, few interactions)
- Lamotrigine (good for women, slow titration)
- Oxcarbazepine (better tolerated than CBZ)
- Carbamazepine (older, effective)
- Lacosamide (newer, well-tolerated)
06Warning ⚠️ Women of Childbearing Potential
Avoid valproate
- Valproate: highest teratogenicity risk
- Prefer: lamotrigine, levetiracetam
- Folic acid 0.4-4 mg daily
- Preconception counseling essential
- Plan pregnancies
07Action Start Selected AED
Monotherapy first
- Start low, titrate slowly
- Target lowest effective dose
- Allow 2-3 months for steady state
- Check levels if available (PHT, VPA, CBZ)
08Decision Seizure Freedom at 2-3 Months?
Adequate response?
09Action Continue Current Therapy
Maintenance phase
- Regular follow-up (q3-6 months)
- Monitor for side effects
- Assess adherence
- Discuss driving restrictions
10Action Consider AED Withdrawal
If seizure-free ≥2 years
- Discuss risks/benefits
- Recurrence risk ~30-40%
- Lower risk: normal EEG, no structural lesion
- Higher risk: focal onset, abnormal EEG
- Taper slowly over months
11Outcome Long-Term Management
Ongoing care and monitoring
- Path rejoins step 11Shared downstream outcome
12Action Adjust Therapy
If breakthrough seizures
- Check adherence first
- Increase dose if tolerated
- Check drug levels
- Review for triggers (sleep, alcohol)
13Decision Still Uncontrolled?
Switch or add second AED
- Trial of 2-3 AEDs defines drug-resistant
- Switch: if first AED not tolerated
- Add-on: if partial response
14Warning Drug-Resistant Epilepsy
Failed 2 appropriate AEDs
- Refer to epilepsy center
- Consider surgery evaluation
- VNS, RNS options
- Dietary therapy (ketogenic)
- ~30% of epilepsy is drug-resistant
- Path rejoins step 11Shared downstream outcome
- Path rejoins step 08Shared downstream outcome
15Action Generalized Seizure AEDs
Broad-spectrum preferred
- Levetiracetam (first-line, broad)
- Valproate (very effective, teratogenic)
- Lamotrigine (good for women)
- Avoid: CBZ, OXC, PHT (can worsen absence)
- Ethosuximide for absence only
- Path rejoins step 06Shared downstream outcome

What guideline is the Chronic Epilepsy Management based on?
This algorithm is based on AAN/AES Practice Parameter: Treatment of New-Onset and Chronic Epilepsy (DOI: 10.1212/WNL.0000000000005940).
What are the limitations of the Chronic Epilepsy Management?
Known limitations include: Pediatric epilepsy has different considerations; Drug interactions complex - check always; Pregnancy requires specialized management; Status epilepticus covered separately. Individual patient factors may require deviation from these recommendations.
