Has the friend taken the dog for a Neurological consultation? I would think that this would be the first step in finding out what is going on with your friends dog. Most likely an MRI would be in order to help with a proper treatment plan. There are several members with dogs on anti-seizure medications (Alldogboots, 107Barney, Ladymom off the top of my head) and they all started the Dxing process with a Neuro visit. Maybe you could ask one of the above mentioned members for more information. From what I do know, seizures should be controlled by medication or there is a possibility of permanent neurological damage.
To answer your specific question, from what I have read the answer would be yes possibly.
