You mentioned Graves’ leading to mental illness…do you mean if left untreated?? I was under the impression that once euthyroid (really, really) that mental disturbances were no longer a factor. I know that untreated Graves’ can be misdiagnosed as schizophrenia, among other things. As far as I know, the women I know who were zapped with RAI 35 years ago are mentally stable people… I’d hate to think the mental stuff was possibly permanent or lead to mental deterioration even after treatment.
