Over the past year, and especially since the publication of Switched On by John Elder Robison, there has been a lot of attention around a therapy called TMS (or rTMS–Repetitive Transcranial Stimulation).

It’s something I have deep reservations about but others have written passionately and eloquently on the subject. What I want to consider is why somebody would choose to undergo such a therapy that literally changes their mind.

I’m no stranger to the negative feelings that arise when considering the gap between how I perceive myself and what I see when I look in the mirror: that’s a big factor in my gender dysphoria.

I also know first-hand how it feels to be teased and ridiculed for hand flapping, physical clumsiness, social awkwardness, unusual speech patterns and eclectic interests. I’ve had life-long difficulty making and maintaining interpersonal relationships, and I have times where I feel keenly the lack of people with whom I feel comfortable opening up about my problems and feelings.

I understand the drive to make physical changes to one’s body. After all, I’m in the process of seeking treatment to modify my own body, bringing it into closer alignment with what I see in my mind by erasing or concealing male characteristics and developing female ones.

There are two parts to my gender dysphoria. First there is my need to have other people respond to me as a woman, reinforcing my gender identity. Second there is my need to see my own body physically match the mental image I hold.

So as a trans woman I am actively seeking treatment to make changes to my body. This is in contrast to my feelings about my autism. Both my gender identity and my autistic identity go to the very heart of who I am.

The thing is, although I will happily modify the physical characteristics of my body I wouldn’t consider altering my mind. My neurology is inextricably tied to my identity: I feel that changing my mind would make me into a different person.

There’s a line there. I’ve put a foot over that line a few times, testing the water so to speak. I’ve experienced the effects of drugs that affect the workings of the brain: alcohol, marijuana, amphetamines, SSRIs (anti-depressant).

Some of them have positive aspects. For example, alcohol reduces my social anxiety. But there are negatives too: I make poor decisions under the influence of alcohol because it inhibits my self-control and risk-aversion: I’ve gotten myself into some dangerous situations as a result.

Speed (amphetamine) left me unable to concentrate, marijuana was relaxing but caused mild hallucinations and a degree of paranoia. The SSRIs reduced the intensity of my emotions, leaving me feeling numb: in the end I had trouble focusing and engaging with things in my life.

These were all temporary effects: my mind returned to its usual functioning state in time for which I was grateful. You see, I wasn’t myself when under the influence of any of these drugs.

I guess my point is that given the complexity of the human brain and the way its many regions interact it is not possible to adjust one aspect without affecting others. Just as a particular drug affects a small number of electro-chemical interactions in the brain with wider-reaching side-effects, so a therapy like rTMS that alters a small region must cause knock-on changes across the entire organ.

My opinion is that it is not like tuning an engine, a relatively simple system with a limited degree of interconnection and feedback between its components. It’s more like introducing a foreign species into an existing ecosystem. The effects can be slow to manifest, and predictions are error-prone due to the complexity and chaotic nature of the system.

There is no way to know what other effects rTMS would have. It might reduce my social anxiety, but even if that was all it did it would make me respond differently to people I interact with (like alcohol). And if my thoughts and behavior are changed then I’m no longer the same person.

I don’t want to change who I am: I’m comfortable with my identity as an autistic trans woman with all that entails. Changing my body doesn’t affect my personality, my thoughts: I remain me. Changing my mind makes me into somebody else. I would lose the essence of what makes me this particular unique individual, and the thought of that fills me with dread.

This leads me to suppose that for somebody to even contemplate such a thing they must not like who they are. Internalized self-hatred, blaming their neurology for what they see as their failings. It’s like body dysmorphia projected onto the ego, the sense of self. The antithesis of neurodiversity’s principles; an inability or refusal to accept one’s differences.

I see this as a result of thinking colored by the medical model of autism that sees it in terms of pathological deficits, as opposed to the social model which instead looks to society’s failures to provide suitable accommodations and acceptance as the causes of disability.

There’s nothing wrong with my mind: I have no reason to change it. I can’t say the same for the society I live in.
