Question: does gabapentin cause early dementia?
Answer: The greatest risk for Alzheimer's and dementia was observed with valproate. In contrast, medications with no known cognitive adverse effects, which include oxcarbazepine, vigabatrin, tiagabine, lamotrigine, gabapentin, levetiracetam, pregabalin, and lacosamide, did not correlate with an increased dementia risk.
