Syncopal episodes with convulsions

Having a tough time sorting out my girlfriends situation,
She has been having left sided head pain for some time, recently it has gotten worse with numbness to left sided extremities that comes and goes. Occasional left pupil diliation
Syncopal episodes happen four to five times a day, lasting moments up to 15 minutes. With in the last week she has been having convulsion, type activity, it is unlike the clonic/tonic type activity I have seen, and there is no postictal state after.
The convulsions seem non-rythmatic her face grimaces like she is in pain, and she contracts into a semi fetal position. These events happen while she is lying sitting or standing, and is normal tensive with a heart rate in the 80s throughout
She has had an MRI, and a head EEG for three days and all things came back "normal"
Her docotor says "I don't know what is wrong"
And thinks it's in her head. Any ideas on cause, I would like to get this sorted out, she has had three significant events while at work requring EMS be called.
Any help would be great thanks

Hello dear, welcome to the medhelp forum. I can understand your concern over your girlfriend’s health. These episodes could be a type of migraines, which are severe and run in families. The hemiplegic migraine is associated with an aura, presenting with temporary weakness or numbness on one side of body. Headaches follow up and these neurological symptoms may disappear. Migraines are caused by certain triggers like stress, lack of sleep, during a woman’s periods, eating chocolates and caffeine.
Did you ask her for any campy abdominal pain? Check with her if her periods are regular, flow normal or heavy? She needs to be examined by a gynecologist in detail to check for any torsion ovarian cyst or other gynecological conditions. An ultrasound abdomen would be required apart from history and clinical evaluation.
Migraines if confirmed need to be screened carefully. She will need to check for possible triggers from her routine, avoiding them, preventive drugs would include atenolol, nifedipine, anti convulsants like topiramate.  Painkillers like NSAIDS can be used to abort an attack, anti depressants like nortriptyline, fluoxetine and triptans like sumatriptan.
Consult a physician for these symptoms immediately.
You are welcome for any clarification.
Wish you all the best.
