My daughter has been ill since January, 2011. Neurologist, Stanford doctors, Infectious Disease specialists have been unable to diagnose. Could Lyme Disease cause elevated IgE - total mid 500 s as well as non-specific brain lesions? Lesions in r frontal and l parietal lobes. Lumbar puncture normal, Immunoblot non-reactive, most labs w/in norm limits. Many sx mimic lyme. Removed 2 ticks, not sure how long before onset of sx, I m guessing w/in 1 month. Thank-you, Jill Stanley
