I have wondered the same thing, I heard they were but noone can tell me for sure. I had a brain aneurysm clipped on Feb. 15th 2001, my 9 year old daughter has complained about headaches for the last 6 months, I had her eyes checked and they are fine. I asked her Dr. about it and she said to write down the date and time of each headache and we'll take it from there. I hope and pray they are not hereditary. cathy
