20 yr old daughter began to experience brain-fog and lapse in train of thought. She is at a University and is stressing this semester already because of increased difficulty in paying attention. And today her vision is affected where she s says she can t even see the chalk board. I m an MRI Tech and will do a brain scan this Friday. She also has an apt with eye doctor the week as. She is allergic to most every thing with asthma. We even went gluten free but she cannot tell if that s it. Her meds are 2 puffs Pulmicort Flexhaler twice a day. 180mcg 1 10mg montelukest sodium, and one over the counter allergy pill a day. Not Benadryl. She had blood work for slight weight gain that apparently came back normal. She is already suspecting a brain tumor.
