I recently had a seizure and had an mri that showed enlarged brain ventricles(hydrocephalus). My neurologist said there is no blockage so a shunt wont help me. I have head aches everyday now and dizzy spells. She is treating me for migranes. also a anti seizure medicine.I had encephalitus as a child and she says the enlarged ventricles are probably from that. I had a repeat mri 90 days later that was the same. she says its good that the ventricles are not getting larger and its probably been that way since i was a child. So why the sudden headaches and dizzy spells? ive never had migranes before. It seems to be a guessing game. im worried that the enlarged ventricles could be causing more damage. should i get another opinion or does this sound right?
