seizures
"Vimpat is highly effective at controlling my seizures. It causes dizziness at high doses, but this improves when lowering the dose of Lamictal, and greatly lowering the dose of primidone, which also causes dizziness. Vimpat is more effective at controlling partial seizures at high doses when it is nearly a primary medicine. My MD was the Director of Research in the Vimpat study. I have less dizziness at 600 mg/day when doses of other anti-epileptic drugs are lowered."
