I'm and emergency doctor and I'm an Aspie.
I was only diagnosed recently, and I've given a lot of thought to how I manage in a pressured environment dealing with a lot of people, both colleagues and strangers. Here's a few things to consider:
Medicine is good because it works on the apprenticeship model. When you're a student you frequently simply observe doctors interacting with patients. This gives lots of opportunity to mirror - pick the patterns of speech and behaviour that seem to work, and copy them.
You get a lot of instruction, like making eye contact with patients when you intruduce yourself. I still can't shake hands, unless the patient actually reaches out to me first, when I've learned to respond appropriately, but I give my name, smile, look at them for a few seconds, and then just remind myself to glance back at them every so often. Most patients seem quite happy with this, and the more you practice it, the easier it gets. making eye contact when you have a defined role is also easier - you both know the rules, so there's less anxiety.
You can ask people stuff you'd never ask in a social situation. I was surprised when I was in GP/family med for a while and all the depressed people started coming to me. I think it was because I've been depressed, as most Aspies have, pluys I would ask them 'are you depressed? How do you feel about yourself? what's going on at work/home? etc. I can't rely on the nonverbal stuff, and the discovery that people actually want to be asked these questions, want the space to tell you what's going on, was great. Because you're a doc, you don't have to hug them and be empathetic, you just have to be sympathetic, which is much easier.
It gives you space to test things out. Sometimes, when caring for someone really sick, if there was a pause while we waited for results, or something like that, I would put my hand on theirs. A lot of people, especially the old folks, immediately gripped my hand back. It was a bit alarming at first, but now I like doing it. I don't get any physical contact with anyone in my personal life, and so this occasional contact with patients has actually become quite important to me.
there's lots of opportunity to practise interacting with people as a medical student. You likely won't see these poeple again, and you're there to train, so there's less anxiety (for me at least) about each eisode. It's not like socialising at all.
Finally, I do think some aspects of the aloneness of being an Aspie are dangerous. I don't have a supportive family and most people don't 'get' me, so I spend my time away from work alone. Being surrounded by colleagues in the emergency department, being able to chat about complex cases, fool around a bit, and teach junior staff gives me the human interaction I need. I do think that picking a job that enables you to lock yourself away from other people isn't a good idea. Some aspects of HFA do get easier as you get more experienced at interacting with people. I can chat, now, and although I know people still see me as weird, I've worked in the same place for a number of years so I can look most of my colleagues in the eye, and I've even told a few of them I'm Aspie.
Feel free to ask me anything about being an aspie doctor...
