In Need Of Some Answers

My boyfriend, who is 26, was diagnosed with epilepsy roughly 3 years ago. Since we have been together I have been his caretaker. I have been documenting everything as of late, I had the idea to keep a journal. I'm looking for more answers for him. He has been to a sleep study and most of his activity is said to occur in the frontal lobe. That being said, I have seen him have what I think to be seizures with characterisitics from other areas of the brain. Has anyone else dealt with epilepsy being diagnosed later on in life and having different types of seizures. He has symptoms ranging from simple partial seizures all the way up to grand mal, sometimes a combonation of symptoms will occur. Most of the seizures I have witnessed have had what I call the extreme frown face and moaning noise, which I assume is due to vocal cord and muscle tension, but he will also have complex partial symptoms like trying to get up and wander. He has told me from nobody being around to witness previous seizures that he has in fact gotten up and wandered. I have also witnessed him during a recent hospital stay have what I believe are simple partial seizures. He will close his eyes and have visions with twitching movements he is unaware of but is not sleeping. He also experieced jamais vu(derealization) and visual distortion of the room being what he described as tilted. He was also on dilaudid for pain at the time(he had his seizure in the shower this time and cracked a rib), so I don't know if that would have been the cause of any of the visual distortion or visions. Any advice for me?
