I also have idiopathic diagnosis. I suspect I had a Heinz variety before my first t/c when I was eleven. I think my brain was warming up! Have not had a t/c in 4 years, but have partials now that are relatively controlled with meds. Almost croaked 11 years ago went status. Nothing about this disorder susprises me. I try to be grateful but with age depression has been harder to combat...off to the gym I go!
