After a concussion last year my friend developed a severe case of post concussion syndrome and was diagnosed with a MTBI. Subsequently she was knocked out twice in one evening; unconscious for about 2 hours in all.

Since then she started having fainting episodes, prolonged periods of loss of consciousness and seizure (tonic-clonic, myoclonic and absence) activity associated with her migraines; she now gets basilar and hemiplegic migraines in addition to the migraines with aura she had previously.

The migraines are really chronic; she's really light and noise sensitive, the aura symptoms are present almost constantly and any little thing triggers her migraines. CAT scan and 15 min EEG (no seizure activity occured during it and she was on a high dose of gabapentin at the time -prescribed for neuropathic pain) were clear but she's getting more minor concussions all the time because of the migraines/fainting etc.

She also has polycystic kidneys and polycystic ovary syndrome and prior to the concussions last year had experienced about 10 concussions. She had multiple admissions to ED but no one seems to know what is going on or causing the problems.  What is likely to be the cause of the problems and can they be treated?
