I placed it in quotes because I see it as a disputed concept that not everyone considers to be valid, and which doesn't even have a consistent definition amongst those who do. The main problem being that it conflates knowledge of one's own sex with a desire to be the opposite sex. The brain scan research, like the paper you cited, seeks neural correlates for a very strong desire to be the opposite sex, such a strong desire that the subject seeks medical treatment to change their appearance - which isn't really the same thing as having a 'gender identity'. Interestingly, homosexuality is also linked to sex-atypical brain structures, and in studies where this factor is controlled for, the structural differences seen in brains of gender dysphorics all but disappear. Curiously, what is seen instead are alterations in brain networks that mediate body perception, somewhat like what is seen in anorexics (though, by contrast, we don't label them as having a dissonant 'size identity' or anything like that). I see women's rights as being distinct from and in conflict with 'trans rights', and don't really understand what you mean when you say they are the same on an ideological and philosophical level - could you explain further please?

Distinguishing this would require longitudinal studies, optimally from childhood onwards, which was beyond the scope of the present research. Nonetheless, there are reasons to believe that at least some of our observations reflect underlying factors rather than the effects of GD. One reason is that other conditions involving body rumination, such as anorexia nervosa (AN) and body dysmorphic disorder (BDD), are not associated with similar fronto-occipital changes. Although BDD, like GD, has an early onset and is also related to the congruity between body and identity, persons with BDD have been found to display thinner rather than thicker frontal and temporal cortices compared with controls (Buchanan et al. 2013). Among subjects with AN, compared with controls, their cortex has been found to be “thinner” bilaterally in the superior parietal gyrus and in the right inferior parietal and superior frontal gyri, and their FA values found to be lower for the left corona radiate, the posterior thalamic radiation, and the left superior longitudinal fasciculus, but not in the IOF tract, as in the present study (Via et al. 2014; Fuglset et al. 2016).
