[2025-10-01T00:25:09.896091] [PI reasoning] **Selecting the best AED**

I need to answer a multiple-choice question about the best anti-epileptic drug (AED) for a 72-year-old with normal renal function and new-onset focal seizures. The preferred options for elderly patients are levetiracetam, lamotrigine, and gabapentin due to their favorable side effects and minimal interactions. Levetiracetam stands out as the best choice since oxcarbazepine might lead to hyponatremia, while sodium valproate and pregabalin are not first-line options for focal seizures. I'll gather supporting evidence to solidify this conclusion.
