Focal epilepsy — lamotrigine or levetiracetam preferred based on SANAD II trial
Drug selection considers seizure type, comorbidities, pharmacokinetics, teratogenicity, and tolerability
Monotherapy preferred — polypharmacy increases side effects and drug interactions
Drug-resistant focal epilepsy
Defined as failure of 2 appropriately dosed and tolerated antiseizure medications
Affects approximately 30% of focal epilepsy patients
Referral to epilepsy center for surgical candidacy evaluation is standard of care
Temporal lobectomy in appropriately selected mesial temporal sclerosis patients — 60 to 80% seizure-free at 2 years
Surgical considerations
Resective surgery — removal of seizure focus when MRI-visible lesion concordant with EEG
Laser interstitial thermal therapy — minimally invasive alternative for mesial temporal sclerosis
Vagus nerve stimulation — palliative 50% seizure reduction in approximately 50% of drug-resistant patients
Responsive neurostimulation — closed-loop system detecting and aborting seizures
Lifestyle modifications
Sleep hygiene — sleep deprivation is a major modifiable trigger
Alcohol avoidance or minimization — well-established seizure trigger
Medication compliance — most common preventable cause of breakthrough seizures
Ketogenic diet — considered for drug-resistant epilepsy; stronger evidence in pediatrics
Caffeine in excess may lower seizure threshold
Patient Discharge Instructions
copy discharge instructions
What happened and what to expect
You were evaluated for a seizure — a brief episode where your brain had abnormal electrical activity
After a focal seizure, confusion and fatigue for hours is normal and expected
You may not remember the seizure itself — this is typical and does not indicate a serious problem
Driving restrictions
You must not drive until cleared by your doctor — laws vary by province and state but typically require 3 to 12 months seizure-free before driving is permitted
Inform your family members and caregivers of this restriction
Contact your provincial motor vehicle authority if you hold a commercial driving license
Activity restrictions
Avoid swimming alone until seizure control is established
Avoid working at heights or operating heavy machinery
Take showers rather than baths to reduce drowning risk
Avoid situations where a sudden loss of consciousness would be dangerous
Medications
Take your antiseizure medication exactly as prescribed — do not miss doses
Do not stop your medication without speaking to your neurologist — abrupt discontinuation can trigger seizures
Watch for rash if started on lamotrigine — especially in the first 8 weeks; return to ER if rash develops
Watch for mood changes, irritability, or depression if started on levetiracetam
Lifestyle guidance
Get adequate sleep every night — sleep deprivation is a major seizure trigger
Minimize alcohol consumption — alcohol is a well-established seizure trigger
Avoid recreational drugs
Stay hydrated — avoid severe dehydration
Follow-up
Neurology appointment within 1 to 2 weeks — contact your family doctor or the neurology clinic directly
EEG (brainwave test) will be arranged as an outpatient
MRI of the brain may be arranged if not completed in the emergency department
Return to the emergency department immediately if
Another seizure occurs
A seizure lasts longer than 5 minutes or you do not wake up after the seizure
You develop fever, severe headache, or stiff neck
You develop new weakness, numbness, difficulty speaking, or vision changes
You develop a skin rash — especially if on lamotrigine
You are pregnant or may be pregnant
