5 year old. Focal Sensory? Treatment?

Our 5 year old has had a number of seizures since she is 3. They almost always happen within 2 hours of going to sleep. There seems to be a clear link to this happening when she has the flu/fever etc. She has had an MRI which was normal and 2 EEGs. We went to respected neurologist specializing in Epilepsy and he thought she has rolandic benign childhood epilepsy. However he didn't see this confirmed in the EEgs we brought him. He leaned towards not treating with medicine. Last week she had 2 more episodes, and she had a fever/flu. We filmed one of them and shared it with the doctor today. He called me to say that he is thinking we are looking at "focal sensory" rather than what he had thought. So he suggested we start with medicine - ospolot. Starting with 1/4 pill, building up to 1 a day before sleep. He told us that this medicine isn't used in the US (we are in Israel) but that in Europe it is used. So....this is all very new. I'm interested in knowing more about "focal sensory" seizures and/or ospolot. When he thought it was "rolandic benign" it was reassuring to hear that in most cases it is gone by age 16. what about with "focal sensory"? What can we expect etc? thanks
