Treatment of Seizures in Elderly Patients

First-Line Treatment Options

The American Academy of Neurology recommends levetiracetam and lamotrigine as first-line antiepileptic medications for elderly patients with seizures due to their favorable side effect profiles, fewer drug interactions, and good efficacy 1
Levetiracetam is preferred due to its minimal drug interactions, favorable side effect profile, and availability in both oral and IV formulations 1
Valproate is an effective option but requires careful monitoring for thrombocytopenia and is contraindicated in patients with liver disease 1

For status epilepticus in elderly patients, the American College of Emergency Physicians recommends first-line IV benzodiazepines, followed by second-line options such as IV levetiracetam or IV valproate if seizures persist 1, 2, 3
IV levetiracetam is preferred due to its minimal cardiorespiratory effects 1, 3
IV valproate is effective but contraindicated in liver disease 1, 2

The American Geriatrics Society recommends starting at lower doses (25-50% of standard adult doses) and titrating more slowly than in younger adults, and monitoring for adverse effects closely, particularly cognitive impairment, dizziness, and ataxia which can increase fall risk 1

The American Academy of Neurology recommends checking drug levels when appropriate, such as valproate therapeutic range, and monitoring for early seizure recurrence, particularly in patients with risk factors 4
Monitoring for adverse effects at each visit, with particular attention to cognitive function, balance, and coordination, is also recommended 4

The American Academy of Neurology recommends avoiding rapid titration of antiepileptic medications in elderly patients, and not using phenobarbital or phenytoin as first-line agents due to higher risk of cognitive impairment, drug interactions, and adverse effects 1

The American College of Emergency Physicians recommends administering IV benzodiazepines immediately as the cornerstone of acute seizure management, with lorazepam or midazolam as first-line therapy 5, 6

The 2024 ACEP guidelines establish that fosphenytoin, levetiracetam, and valproate have equivalent efficacy (45-49% seizure cessation at 60 minutes) for second-line therapy 5, 6
Levetiracetam is preferred in elderly patients due to minimal cardiorespiratory effects (0.7% hypotension, 0.7% arrhythmias) 6

Point-of-care glucose should be checked immediately, as hypoglycemia is rapidly reversible 7, 8
Electrolytes (sodium, calcium, magnesium) should be checked, as hyponatremia and hypocalcemia can present as new-onset seizures in elderly patients 7, 8
Non-contrast head CT should be performed urgently if focal neurologic deficits are present, or if the patient does not return to baseline within several hours 7, 8
The risk of structural lesions (stroke, tumor) is increased to 34-40% in patients over 60 years old 7, 8
