Need help figuring out my Brother's Seizures.

It startd through the past couple of months, my brother would have those moments where he'd be working, communicating or just normally going about his day, but all of the sudden he'd need a moment to regain his senses, he's aware of them, he'd try and lean towards something to support him, tries to concenrate to get pass it, with a certain movement in his throat ( neck ) as if he's trying to swallow, but nothing exccesive. 

I talked to him about it and he said he'd feel like having a very unpleasant Deja-vu, feels quite upset and uncomfortable for those few seconds, then goes back to normal again. i thought they were panic attacks or something due to his stressful work. he expected it to stop if he managed to get himself less stressed. 

then a last week he was sleeping in my room because we had people over sleeping in his, and ive woken up twice to the sound of him doing a certain swollowing movement excessively - which i'm familiar with it having nose allergies when sometimes we feel like scratching the inside of our throats-  while his hands shook, i freaked out and asked to stop cause it'd hurt his throat, i was sleepy so can't remember if he had responded immidately, but i think he did. 

i got a little concerned but got to sleep eventually, then the next day i woke up to find him standing in front of the bathroom door, his hands posed as if he's eating something, shaking, and he was doing that swallowing thing again and it looked more like chewing, with blood & saliva dripping out of his mouth, i ran to support him but he was standing still, kept calling his name, held his face, looked at him but he wouldn't respond, so i basically watched him having his first seizures until he responded, led him to my bed and asked him if he remembers what just happened, he couldnt, then he was confused and upset and got back to bed. slept for a few minutes and went to the toilet again, had a shower, got dressed and went to work. 

i was completely frightened and broke down but then looked up these symptoms and got to understand what this was, eversince this happened i spend hours day searching into it to understand it more, because i live in a little town in egypt where i can't entirely trust Doctors. from what i gather i feel like his earlier condition looks like absence sezirues which he can contain/control. 

this is when i started ear-dropping on his room and constantly check on him, then ive started witnessing the seizures he has while asleep, it has a certain pattern as far as i noticed, starts by a loud groan, then he waked up frightened, half sits up and says little prayers to comfort himself from being afraid, then he goes into a 30/40 seconds seizures where he's do that swallowing throat movement excsseievly again, hands shaking slightly, stares, looks pained. then either wakes up or goes back to sleep, depends on whether i decide to wake him up make sure he's alright or not want to ditrupt hes sleeping patterns since i'm aware it could make it worse. 

next day he shows me a bite on his tongue and wonders how he's got it, i looked at him suggesting it's possibely caused by these seizures, i tend to joke about it to lessen his stress about it, we tend to call it "The Glitch", it cracks him up. but he feels bad for me for not being able to sleep since it all started to happen, i tend to either have naps when he's not around, but can't keep doing so since i've work to take care of. 

now it's been days and i'm aware of two seizures he has daily while asleep, one of them starts a couple hours after he falls asleep, and the other is about a couple hours before he wakes up, groaning, wakes up terrified, has his seizure, sleeps again. 

but these are only the symptoms i've witnessed, i never saw what happened when he groans loudly, and i wonder if he has them while being awake, i wonder if he ever hurts himself being unaware, this is why i'm trying to keep an eye on him, but it's becoming highly dificult since it terrifies me, but i'm trying to contain my fears to be able to help him being diagnosed accurately. 

so as far as i know he seems to have Nocturnal Seizures at night and perhaps Absence Seizures which he can controle day time, i sinccerely hope they don't devolop into something more severe. 

we're seeing a neurologist next week for a brain scan, Drs here would only recommend an EEG but i'll try to push him to do an MRI, and EEG, perhaps an out patient EEG as well ( as one of the lovely helping people here have suggested ) 

now my questions are as follows: 

1- does he need me around when he has his seizures or should i start learning to fall asleep at night avoiding running to his room constantly to check on him? ( he's not aware of those and they don't bother him but i wonder if it could devolop into something that might hurt him ) 

2- ive read too many articles about people struggeling with apilepsy for a long time with limited chances to be cured, and they're not as much as those who have mentioned not having seizures using meds, so i need a light of hope that my brother could at some point be Seizures Free?

3- would should he be doing to try and prevent them from happening, as in daily habits or sleeping habits to be changed?

4- is there any type of food or drinks that he should quit? or actually any type of food that helps soothing him and making him less stressed and more able to sleep ( of course aside of meds )? 

5- is it wrong to speak to him or try to reach him when he's having a seizure? should i comfort him afterwards or let him not be aware it happened? if he's aware of having them would that increase the possibilty of him being able to control them?

6- is there a chance he's harm himself or anyone else while having them?

7- is it true that some of the meds would make him gain more weight? he's a tad over weight already 

8- would working out help him?

and any advices that could help me to be less frightened at night and be able to cope with his new condition. 

thank you very much in advance. 

cheers.
