My daughter had very mild episodes as a child. Mostly spacey episodes and a dislike of crowds. She functioned very well and was a competitive soccer player. At puberty she started to get severe migraines, mostly aura without headache. She did get headaches daily but not necessarily migraines. She had a particularly bad aura of upper right loss of visual field. It never went away and was diagnosis as a stroke. She went on to have a brain stem stroke or a complicated migraine in her brain stem with lost of strength on the left side, loss of taste on the left, ataxia, tachycardia, dizziness, expressive aphasia. altered temperature sensation, severe right upper abdominal pain, and more symptoms of dysautonomia. It turns out she had a PFO (patent foramen ovale) a hole in her heart that has been correlated to migraines. The hole was closed and her headaches disappeared immediately. She has not had anymore migraines but developed POTS. There is a disagreement between neurologists and all other doctors as to the cause, stroke vs. complicated migraine. She recovered slowly and was doing well until she had an ERCP and had her sphincter of Odi cut. That got rid of her severe pain but brought on horrible POTS. She is slowly getting better but still we live minute to minute with a daily array of dysautonomic symptoms. So which came first ... we don't know, but it all seems related. So after my divergence I guess her is born with it and trama combined.
