I find it amusing my disability may come from a 'retro' virus (and transgender)
http://sacfs.asn.au/news/2009/10/10_11_xmrv_retrovirus.htm
Now of course its still early days. There's been other biological factors found for this illness still considered by many even in the medical profession as purely psychological.. yeah they can tell that to the blood tests where i was eating for three and my body still thought it was so starved that canabilising my muscles and bones seemed a good idea to it.
It's a big puzzle and with many complicated aspects, what is thought in one discovery to be causal may instead be consequential and vice versa. And it may well be the umbrella term covers more than one illness related causally or unrelated but for similarity of symptoms.
Seem familiar?
There are quite a few similarities between that and much in the Transgender world.
Of course even with the name conflicts between Chronic Fatigue Syndrome, Fibromyalgia and Myalgic Encephalomyelitus and whether or not fibromyalgia is a seperate similar maybe related illness or merely just the side of CFS that gets more muscle and joint pain compared to the exhaustion and cognitiove imapirment on the other with a false-divide with lots of people having a chunk from each camp and being difficult to shove into either box there has still not been in my experience any of the vicious vitriol and ad hominems amongst sufferers in these debates.
Unlike the TS anti-TG extremists who in the comments at Bilerico recently went on and on in attacks, but again fell silent when those with an ounce of scientific literacy challenged them and called their pseudo-science and cherry-picked science bluffs. (when oh when will they respond to the discoveries of cross-sexed brain neurology of gays and lesbians and the inclusion of non-ops in some of those studies they tout as proving their claims?)
There's lots of pseudo-science around CFS too.. people get desperate so some of those without conscience will try and fleece sufferers. Other sufferers try all sorts of things and if they are lucky enough to go into remission will celebrate whatever they were taking or doing at the time.. alas all too often theres no evidence it actually will help anyone else. Heck years ago one teenage girl was so desperate she trepaned herself.. drilled a hole into her own skull with a powerdrill to expose her brain!
For those used mostly to my posts being directly related to transgender issues its worth looking at the experience of people with CFS. I'm lucky that I can string written sentences together with a reasonable enough degree of coherancy that the cognitive impairment problems don't so often show.

And with CFS ignorance and bias amongst the medical fraternity ignoring the evidence, ignoring the science also kills

And of course there are lots of ways that society punishes the disabled.. centrelink is a minefield of ablist beaureucratic traps seemingly designed for no other purpose than to make disabled peoples lives more difficult or to find excuses to cut their pensions.
So there is good news.. but only another piece of the puzzle at the moment, no new treatments are available and there is only a chance this discovery will lead to some.
And its a good opportunity to think about the issue, and for those without disability to think about those around them whose quality of life and their very continued existence depends on society fulfilling the social contract and looking after them.. which all to often it's failing to do.

Missrepresentation of Science and transgender politics
You see despite basic scientific methodology people from several positions are making claims not supported yet by the data as if it were totally conclusive and using that as an attack on others.
What do we have? We have good leads from small studies of small sample sets that transsexuals have several brain differences from averages of their assigned birth sex that are closer to their self-identified sex-identity. Both in structure and in function. One gene so far has been found to be more common amongst TSs too. (Zoe's blog is a great source for this stuff)
But what about non-transsexual transgender? Well they haven't done the same studies on genderqueer, bi-gender, crossdressers etc yet. So as science goes it falls into the realm of 'maybe'. Actually 'maybe but we don't know yet'. That doesn't mean 'no' it doesn't mean 'yes' it means 'maybe'. It means that the simple testable hypothesis that the same or similar related phenomena exist in these others could be tested but hasnt yet and until its tested we dont know. Either way.
Thats plain ordinary scientific method, something I got taught in highschool and I would have thought everyone else would have got taught that too.
So what's the problem? Well some are claiming that the tests done thus far say things they do not. The tests needed to say that crossdressing is not biologically caused have not yet been done, yet some are claiming that because 'there's no evidence' that it is not so... but hang on, the neccessary tests havent been done! To test if the same cause causes both you have to do the same test on both! Not biological tests on one but only psychological tests on the other!
Others are claiming the studies done support only their version of the definition of transsexual or only binary-gender identity etc but the selection criteria for these studies didnt split the subjects up like that! To get those results all you have to do is seperate your test subjects into different catagories and compare the results of each catagory.. you likely need more test subjects though as you need a representative sample of specimens from each group, tricky when brain-dissection is one of the studies and expensive for FMRI scans. But doable.. but not yet done either!
Now some folk gave trouble with coping with ambiguity, with living with a maybe till the answer is found. Some even have trouble understanding that to say something is possible (and testably so but not yet tested) is not saying it is definately so, it is however saying that it is not yet definately known as not so.
Science works by refuting testable hypotheses not making stuff up, saying anything untested is true nor by saying that something cannot be so till its proved to be so.. thats all creation-science level nonsense. The stuff that was the laughing stock at the Dover evolution trial, in fact very much like Dembski's non-science.
Sure some people have been let down by the education system and are scientifically illiterate. Not their fault but if they want to use studies to validate their claims and invalidate others at least some basic undersanding of scientific methods a good idea and some self-education might be beneficial.
Other people though seem to play the same tune no matter how refuted, ignoring the facts of scientific method and continuing to make spurious claims. Mistakes happen, everyone gets things wrong sometimes, but to maintain such arguments constantly is falsehood, self deception at best and deliberate lying is definately possible.
It's a common enough tactic. The 'repeat the lie often enough' tactic of hate-groups religious and otherwise.
It's time these people were called out on them though. Gently at first, some will simply be mistaken. But certainly because allowing these myths to propagate unchallenged is often to allow manipulative divisive hate-speech to propagate unchallenged.
The deliberate anti-science, unscientific, unethical missrepresentation of science in order to denegrate others and propagate divisions and hate and various ideological positions is abominable.
Much more study needs to be done on transsexuals, on intersex, on crossdressers, genderqueer, bi-gender etc in verifiable sciences like neurology and genetics to rule that out first. Especially as psychology is a kind of speculation, like taxonomy before genetics, a simple attempt to explain complex systems with only a minute amount of data. It must cede to the physical sciences in all things at all times.
And last of all, from a Human Rights perspective even were there no biological causation for ANY of it, not even for any transsexual the hman rights claims would not diminish one iota. Because human rights are filled with choices at every level, choices of religion, expression, medical treatment as just some examples. Check out the Yogyakarta Principles on that. These attacks on others using missrepresentations of science involve at their heart a disregard for human rights of others in order to propagate their preferred (and usually self-serving) ideology.
It's time to call out missrepresentations of science used as tools of hate for what they are in transgender politics as much as GLB politics (including the anti's). Whether hatred of non-bianary folk or of binary folk, of gay-supporting Tgs or TG-supporting gays etc etc etc.

Crossdressing and Biological Causation, a lack of studies doesn't mean a lack of causation
But there's really a simple way to say it.
Some folk quite rightly disregard the past 'evidence' and 'theories' of psychiatry and psychology regarding homosexuality and transsexuality yet insist on still applying them to crossdressing/transvesticism and/or other parts of Transgender.
It's hypocracy, a clear double-standard.
For those arguing Transsexuals have a biological causation (which the science definately supports) they say rightly that the biological evidence is more valid than the psychiatric... unsurprising ad fairly safely valid.
But they often claim there is no evidence for a biological causation of crossdressing etc...
An archaeologist I know often says 'absence of evidence is not evidence of absence'. But importantly in this case... no-one has looked yet! Absence of Studies is not Absence of Evidence
Pretty simple notion.
Possibility 1. Crossdressing is caused by a mild case of the same cause as transsexualism.
How do you test it? Do the same tests on crossdressers thats found evidence for biological causation in TSs and see if you find milder versions of the same as predicted.
Possibility 2. Crossdressing is unrelated to the cause of transsexualism.
How do you test it? Do the same thing as testing possibility 1.
Posibility 3. Crossdressing is also biologically caused but from a different causation to TS.
How do you test it? First rule out 1 and 2 by doing that test. If that doesn't work then look for other biological causes, functional MRI scans and other brain examinations that have found biological factors in homosexuality etc may provide clues as to what else to look for.
Possibility 4. Crossdressing is not biologically caused but is purely psychological.
How do you test it? Rule out 1 and 2 with that test, then rule out 3 by searching for and not finding any biological cause.
So as those tests aint been done yet all those folk who say its purely psychological are full of it.
It doesn't matter how many psychological studies have been done on it either, that has no bearing on whether or not there is a biological factor, component or causation.
And the 'it's understood as psychological already' argument is full of manure too. Science regularly re-asseses old ideas and tests new explanations. The discovery of the bacteriological cause of stomach ulcers is a good example.
I keep running into anecdotal evidence that crossdressing is inherited. Crossdressers finding a parents clothes and book stash after their deaths I've heard of plenty through to one of the FtM CD friends of mine discovering a coworker is a closeted MtF CD whose brother also turned out to be a CD. Those sorts of cases alone suggest its worth looking into if these are just coincidences or whether incidence of CDs are far more common than usually assumed and whether it is an inherited trait.
And some of the scientists predict that the rest of TG is biologivally cuased. From one of the comments in the above link:
riki said...
I am doing a PhD on the political and social implications of the brain sex theory of trans. My assessment is that there is certainly more evidence for that theory than for any other, but that it is far from "proven", and that many biological hypotheses have been falsified on the past (EG the HY antigen in the 70s and 80s). The psychological theories have very little evidence to support them.I interviewed Dick Swaab, whose lab produced the BSTc research that is the strongest evidence for a neurological correlate for trans. It should be noted that one of the six MTF transsexual people in the original 1995 Zhou study had never transitioned, but insisted that they had a female gender identity. It sould also be noted that the 2002 Chung study found that the difference between males and females in the BSTc does not occur until after puberty, which poses some problems for a pre or early post natal hormonal causation theory.
Swaab thinks the BSTc is probably a part of a network in the brain involving the hypothalaumus and cortical areas.
"We only, by accident, hit on a little bit of it"
He also explicitly supported the idea that there is a biological causation for the whole range of gender identity variations:
"I think we talked about a scale like the Kinsey scale for sexual orientation – we should also have a gender identity scale. It is not either this or that; there is also something in between. The distribution will not be simple, but here will be people somewhere in the middle."
"So it is not the entire brain that is switching, it is some systems, and that may also be the explanation for the [gender identity] scale. Some systems do switch and others don’t and it depends on which systems have switched where you enter on the scale."
Other recent research (as reviewed by Zoe in earlier blogs) also supports the idea of certain sex differentiated brain areas being switched in ts or tg people while others are not.
So if that is the opinion of Swaab, perhaps the best qualified scientific researcher in the field, perhaps we can accept that tg is as likely to be biological as ts?
Now even if it's not the case that it's biologically caused we won't know for sure till we test for it! so everyone who keeps on about it being certain that CDing is unrelated causilly to TS need to STFU cause we don't know that cause the studies aint been done yet! And to the scientificly literate you look like either ignorant or lying.
Besides, even if it were to turn out to be purely psychological, which I doubt, it's still ethical. And as such should no longer be considered any less valid as homosexuality or any other ethical form of self-expression.
Absence of studies is not absence of evidence.
So it's about time people stop throwing the non-transsexual transgender folk under the bus too.
