I know someone who is a 17 year old girl and is having major head problems. For over a year now she has basically had a constant headache. She went to a nuerologist a few months ago and he gave her medicine but it does nothing. She just went again today and they gave her more of the same thing and I doubt it will help. She goes back in two months and if this doesnt work then she has to take some kind of seizure medicine that is very bad and lowers your IQ and stuff.

Here is what she complains of:
Constant headaches,
sensitivity to light and noise at times,
memory loss,
trouble recognizing things at times (including myself who she sees almost every day),

she has had brain xrays and all kinds of stuff. i want to help her but i cant and i want to know what could be wrong with her. it is extremely stressful for her and it is making it difficult to live a normal life for a 17 year old girl.

other info:
she is light... probably about 5'8" and 100 pounds,
she gets sick very often and easily,
i cant think of anything else right now

any info or ideas would be great
thanks
