question: my daughter has a cavernoma in her occipital lobe. She had a fit when she was three, and I insisted her to have a MRI when she fainted twice, some months ago (she is now 21) because there are other 3 members of my family with cavernomas. Hers is syntomatic as she gets to see lights, spots when she is tired. After the fainting she saw those lights for almost a month. Her neurologist said that its cavernoma is asyntomatic, which obviously is not. We did not received further advised about lifestyle or medication, wheareas my niece (31) has been advised to avoid certain sports, has been medicated. She is planning to go to Peru, can altitude affect her condition?
