Help with daughter

two months ago, my 20 year old daughter had an "episode" where her left arm and leg went limp. Had CAT, MRI, EEG and nothing showed up. Same kind of episodes have been continuing. They differ somewhat each time, but mostly left arm and leg tingly and limp, slurred speech, sometimes seizure activity, sometimes confusion to the point of not knowing where she is, birthdays, age etc. pain and pulsating beat behind right eye, dizziness. A few times, there have been a headache in back right side, but not all the time. She went to cranial sacrial doctor and symptoms went away for 2 weeks, then gradually back. Also, going to a chiropractor. He did xrays and confirmed what the cranial dr said that her c1 is misaligned, and also c5 and c6. He believes it is a type of migraine. Sometimes hot compresses on her neck will relieve some of the symptoms. Also, if she pops her neck, it helps for awhile, but they usually return. These episodes can last for an hour or so to several hours or a couple of days off and on. Afterwards, she is very weak. Please tell me if anyone has experienced anything like this with migraines. The neuro is saying it is just stress and has dismissed her. I don't believe that since the symptoms get relieved with manipulation and heat. I do understand stress can be a trigger and not denying that. I am so worried and don't know where to turn. She gets dismissed at every turn. She has seen 2 psychiatrist and tried meds but NO help. She has been to counseling 2x but doesn't seem to get anywhere with it, but I suppose will continue. At this point, I am ready to try anything. Please HELP
